Published: August 2021

To investigate the mobility patterns of Neanderthals and modern humans in Europe during the Middle-to-Upper Palaeolithic transition period, we applied strontium isotope analysis to Neanderthal (n = 3) and modern human (n = 2) teeth recovered from the site of Fumane Cave in the Monti Lessini region of Northern Italy. We also measured a large number of environmental samples from the region, to establish a strontium ‘baseline’, and also micromammals (vole teeth) from the levels associated with the hominin teeth. We found that the modern humans and Neanderthals had similar strontium isotope values, and these values match the local baseline values we obtained for the site and the surrounding region. We conclude that both groups were utilizing the local mountainous region where Fumane Cave is situated, and likely the nearby Lessini highlands and Adige plains, and therefore the strontium evidence does not show differening mobility patterns between Neanderthals and modern humans at the Fumane site.

Background

Despite considerable efforts to promote condom use, sexually active people in sub-Sahara Africa still engage in risky sexual behaviours, with condom use relatively low. With this high vulnerability of these persons to HIV and sexually transmitted infections, research related to exposure to family planning messages to help curb this trend remains sparse. This study examined how exposure to family planning messages in the midst of some socio-demographic factors is associated with consistent condom use among sexually active never married men in Ghana.

Methods

Data were obtained from the 2014 Demographic and Health Survey (DHS) of Ghana. Only never married men (15–64 years) who have had sexual experience in the last 12 months were included in the analysis (N = 971). Frequencies, percentages, chi-square tests and binary logistic regression analyses were carried out. Results of the binary logistic regression analysis were presented using crude odds ratios (cOR) and adjusted odds ratios (aOR).

Results

The results showed that only 26.15% of sexually active never married men in Ghana consistently used condom during sex. Men who were exposed to family planning messages were 51% more likely use condom consistently compared to those who are not exposed [aOR = 1.51, CI = 1.04–2.18]. In terms of the covariates, the likelihood of consistent condom use among men in Ghana was lower among those aged 35 years and above compared to those aged 15–24 [aOR = 0.46 CI = 0.21–0.99]. The odds of consistent condom use among men increased with level of education, with men with higher level of education having the highest odds of consistent condom use compared to those with no formal education [aOR = 9.98, CI = 2.05–48.46]. Men of the richest wealth quintile were more likely to use condom consistently compared to those of the poorest wealth quintile [aOR = 2.62, CI = 1.30–5.27]. Higher odds of consistent condom use was found among men who dwelled in the Central, Northern, and Upper East regions compared to those of the Western region.

Conclusion

Our findings have established a strong association between exposure to family planning messages alongside age, educational level, wealth, and region of residence and consistent condom use. Men exposed to family planning messages were more likely to use condoms consistently. Designed programs should use intervention strategies that focus on interactive and participatory educational activities to improve sexually active men’s interpersonal communication on family planning messages, especially on consistent condom use with their sexual partners.
Are suspensory ligaments important for middle ear reconstruction?
Authors: Brister Eileen Y. , Withnell Robert H. , Shevchenko Pavel , Richter Claus-Peter
Published: August 2021

As the resolution of 3D printing techniques improves, the possibility of individualized, 3-ossicle constructions adds a new dimension to middle ear prostheses. In order to optimize these designs, it is essential to understand how the ossicles and ligaments work together to transmit sound, and thus how ligaments should be replicated in a middle ear reconstruction. The middle ear ligaments are thought to play a significant role in maintaining the position of the ossicles and constraining axis of rotation. Paradoxically, investigations of the role of ligaments to date have shown very little impact on middle ear sound transmission. We explored the role of the two attachments in the gerbil middle ear analogous to human ligaments, the posterior incudal ligament and the anterior mallear process, severing both attachments and measuring change in hearing sensitivity. The impact of severing the attachments on the position of the ossicular chain was visualized using synchrotron microtomography imaging of the middle ear. In contrast to previous studies, a threshold change on the order of 20 dB across a wide range of frequencies was found when both ligaments were severed. Concomitantly, a shift in position of the ossicles was observed from the x-ray imaging and 3D renderings of the ossicular chain. These findings contrast with previous studies, demonstrating that these ligaments play a significant role in the transmission of sound through the middle ear. It appears that both mallear and incudal ligaments must be severed in order to impair sound transmission. The results of this study have significance for middle ear reconstructive surgery and the design of 3D-printed three-ossicle biocompatible prostheses.
Facilitating departures from monolingual discourses
Authors: French Claire
Published: August 2021

This article locates and critiques monolingual discourses within applied performance praxis in the United Kingdom and South Africa, suggesting starting points for facilitating multilingual actors’ vast linguistic resources. Set out as a theorized reflection of praxis, I interrogate how the facilitator can draw from actors’ linguistic resources without perpetuating dominant and potentially damaging language ideologies, by which I refer to the socially shared beliefs about language that shape and are shaped by language use. I discuss the powerful language ideologies connected to so-called ‘standard’ English and constructed by dominant institutions to discover how they are reproduced in performance praxis. I also analyse performance examples engaging complex linguistic conditions related to both student and refugee groups in the United Kingdom and South Africa to discuss varied facilitation approaches in context. Through my reflection, I reveal the complexities and opportunities for the facilitator navigating the socio-culturally and politically fraught terrain of language.
Language acquisition and identity-making: Applied theatre as a mediating practice with Syrian refugees in Europe
Authors: Skeiker Fadi , Morris-Skeiker Myla
Published: August 2021

This article addresses the potential use of applied theatre in facilitating new language acquisition among refugees who are resettled in European countries such as Germany. The article charts the applied theatre work carried out by one of the authors with Syrian refugees in Europe, with a special focus on participant reactions to the host country’s expectations surrounding language acquisition and identity-making. The authors challenge current ‘integration’ practices that prioritize focused language learning as a major indicator for the refugees’ re-nationing process, arguing for higher consideration of the trauma surrounding displacement, especially when refugees have first arrived in their host community.
Community-based performances of harmonious diversity: Happy talk and utopian performativity in Playback Theatre
Authors: Snyder-Young Dani , Flassen Maren
Published: August 2021

In this article, we examine a Playback Theatre performance in which audience members perform their appreciation for living in a diverse community, engaging with the performativity of happy talk surrounding diversity. Happy talk is largely considered to support the status quo of White supremacy, letting those who benefit from dominant systems of power off the hook. However, in this event it appeared to operate instead as a utopian performative. The racially and ethnically diverse storytellers in the workshop narrate positive stories about the diversity in their community, and they do so for a reason. This article looks at the hope animating the event.
Research-based theatre across disciplines: A relational approach to inquiry
Authors: Shigematsu Tetsuro , Cook Chris , Belliveau George , Lea Graham W.
Published: August 2021

Research-based theatre (RbT) is an innovative research methodology that draws on theatre practices and conventions to engage in and share research. It is an inherently collaborative and relational methodology, inviting research participants, artists and researchers to take part in embodied data generation, analysis and knowledge-exchange activities. This methodology encompasses writing, rehearsing and performing a research-based monologue, scene or play. In this article, the authors share three recent examples from interdisciplinary projects where researchers and artists engaged with different communities to dramatize data using an RbT methodological approach. To add to literature in the field, the authors consider their experiences leading RbT projects in three disparate fields: theatrical, social and therapeutic. The authors explore the question of how RbT transforms relationships and how relationships transform RbT.
Young People as Legislators: Legislative Theatre and Youth Parliament
Authors: Elliott Matthew
Published: August 2021

Young People as Legislators is the result of a six-month Legislative Theatre project with Collective Encounters Youth Theatre, Youth Focus NW and Youth Parliament UK. The project formed part of a wider scheme of practice as research that explored youth theatre practice as political engagement for young people. Legislative Theatre practice was utilized to work alongside the Youth Parliament’s Make Your Mark scheme, an annual poll for young people to decide on campaigning issues. In this article, I consider three elements: tokenism in youth engagement, differing experiences between artistic process and product, and applied theatre’s inability to develop long-term effects. Employing the critical theories of Paulo Freire, the article regards the practice as a failed attempt to develop critical youth theatre practice. I argue that the Legislative Theatre project led to uncritical engagement and no political change due to partner organizations regarding the theatre practice as a service to satisfy their own targets and requirements.
Correlation of Angle SNA to Angle NSAR in Normal Occlusion, Class II Division I and Class III Malocclusion in Vidarbha Region - A Cephalometric Study
Authors: Jawalekar Rashmi , Hazare Pushpa , Kamble Ranjit H. , Jadhav Vikrant V.
Published: August 2021

BACKGROUND Facial prognathism may be because of prognathic maxilla, prognathic mandible or aggregate of both. Numerous studies performed to diagnose a single morphological feature commonly producing protrusive relationship, revealed that ‘a single morphological feature does not ordinarily produce a protrusive relationship. Existence of structural imbalance in one area also affects the nature of balance in other areas. A number of separate but inter-related cause and effect factors tend to augment each other in a cumulative and composite manner. Effect of marked discrepancy of an individual’s facial part could be cancelled or nullified by deviation of another part in opposite direction, ultimately resulting in good facial harmony. In this study by means of cephalometric roentgenography, the relation between Angle SNA and Angle NSAr was assessed in Vidharbhites, having normal occlusion, Class II division I and class III malocclusion. METHODS 40 individuals of normal occlusion, Class II division I and Class III Malocclusion, each between 16 and 25 years were analysed. These subjects were selected from patients reporting the outpatient department of Government Dental College, Nagpur. Statistically correlation between angles SNA and NSAr at level of significance 5 % was assessed. RESULTS After data collection a thorough observation & analysis was done and co-relation coefficient between SNA angle & NSAr (F--1.054 M--0.7981), also standard deviation of angular cephalometric measurement between males & females was found out in the population, leading to discussion on topic ‘Facial prognathism is due to maxillary prognathism, mandibular prognathism or combination of both’. In Females SNA was found to be 81 - 800 1.91310 and in males SNA was 82.1660 4. 380 respectively. CONCLUSIONS The results inferred that “Marked part of variation in Angle SNA can be explained by variation in Angle NSAr. KEY WORDS Angle SNA, Angle NSAr, Correlation
Diode Laser Has an Additional Benefit When Used with Conventional Scaling and Root Planning for Chronic Periodontitis Treatment - Comparative Analysis
Authors: Deswal Himanshu , Bhardwaj Amit , Grover Harpreet Singh
Published: August 2021

BACKGROUND Almost 47 % of the population over the age group of 30 is affected by chronic periodontitis. Although the first and gold standard therapy in periodontal treatment is scaling and root planing (SRP), which is a non-surgical approach towards treatment, yet another therapy for the treatment of chronic periodontitis is to irradiate the periodontal pockets with laser. The purpose of this study was to confirm as to whether the use of diode laser (800 – 980 nm) as adjunct to scaling and root planning (SRP) improved the results of conventional mechanotherapy in the treatment of chronic periodontitis patients. METHODS In this study we designed our groups in such a way that 40 patients (20 males and 20 females) with two deepest nonadjacent pockets ≥ 5mm in two different quadrants were selected. In this study each treatment group belonged to a separate quadrant of the mouth. One group was allotted to SRP group while the second one was allotted to SRP + Diode Laser group. Clinical parameters like (Probing Pocket Depth (PPD), Clinical Attachment Level (CAL), Bleeding on Probing (BOP) in chronic periodontitis patients were measured and evaluated at baseline, after 1 month and after 3 months of the treatment. Statistical analysis was also done intra group and inter group. RESULTS From this we infer that PPD was significantly reduced in SRP and SRP + Diode laser groups from baseline and post 1 month (P < 0.001), between baseline and post 3 months (P < 0.001) and between 1 month and 3 months (P < 0.001). There was also significant improvement in CAL in SRP and SRP + Diode Laser groups from baseline and post 1 month (P < 0.0001), between baseline and post 3 months (P < 0.0001) and between 1 month and 3 months (P < 0.0001). BOP also reduced in SRP and SRP + Diode Laser group from baseline. When SRP and SRP + Diode laser groups were compared they showed non statistically significant results but individually both the groups showed statistically significant results. CONCLUSIONS The results of the present study indicate that, comparison of SRP alone group which is a conventional method with SRP as adjunct to Diode laser group i.e., a non-surgical approach showed improvement of CAL and also reduction in PPD and BOP for the treatment of chronic periodontitis patients.

Comparative Evaluation of Necessity of Antibiotic Administration Following Dental Extraction among Population of Age Group 30-60 Years - Triple Blinded Randomized Controlled Trial
Authors: Sivakumar Sasidharan
Published: August 2021

BACKGROUND The use of antibiotics as prophylactic prescriptions remains a controversy in dentistry. The current study was done to evaluate the necessity of antibiotic administration following dental extraction among population of 30 – 60 year old age groups. METHODS This is a triple blinded trial with trial registry number CTRI / 2019 / 12 / 022342 in which the 60 study participants were randomized and allocated in a ratio of 1 : 1 : 1 to three groups A (amoxicillin 500 mg t.d.s), B (clindamycin 150 mg t.d.s as a mouthrinse), C (no antibiotic) by lot method. The study proceeded after ethical committee approval and informed consent from the participants. Medically compromised patients, patients in menstruation period, lactation and pregnancy period, test drug hypersensitive patients, tooth with abscess or cyst were excluded and patients of 30 – 60 years old reporting with the complaint to Best Dental Science College, Madurai, were included in the study. The tooth was extracted, and evaluated on 3rd, 7th and 14th day post-operatively. RESULTS The non healing parameters were observed in percentages of 9.7, 6.2 and 6.2 in group A, B and C group during the 14th day clinical evaluation. The presence of non-healing parameters was insignificant between three groups. CONCLUSIONS Prophylactic antibiotics following dental extraction is unnecessary until the patient is at a state of high risk of infection. Thereby, as a dentist we could combat a step towards a developing major public health problem, “Antibiotic Resistance”.

Published: August 2021

BACKGROUND Diabetes mellitus (DM) is associated with a number of ocular complications such as diabetic retinopathy, cataract, refractory deviations, oculomotor nerve palsy etc. Recently, problems involving the ocular surface, dryness in particular, have been reported with dry eye symptoms, indicating a clear role for tear film abnormalities. The objectives of this study were to estimate the prevalence of dry eye and dry eye related ocular surface changes in diabetic patients, and to study the association between diabetic dry eyes and its relation to age, sex, glycemic control, duration of disease and diabetic retinopathy METHODS A hospital based clinical study of 100 diabetic patients who presented to the Department of Ophthalmology, Al Ameen Medical College and Hospital, Vijayapur from November 2019 to November 2020 was conducted. Detailed history was recorded. Assessment of anterior segment via slit lamp biomicroscopy was done. The examinations for dry eyes included Schirmer's test, tear break-up time, fluorescein and rose bengal staining and a questionnaire. The retinopathy was examined by ophthalmoscopy and was recorded. RESULTS Of the 100 diabetic patients, 2 (2 %) were type I and 98 (98 %) were type II diabetes. The mean age of type I group was 30 ± 0 years and 57.55 ± 27.07 years in type II group. 50 % were males in type I group, and 51.47 % in type II. Fifty nine (59 %) patients had dry eye. The prevalence in type I was 100 % and in type II was 58.16 %. Dry eye prevalence was maximum in those between 51 to 60 years of age (55.77 %). A 2.65 fold increase was found in the odds for dry eye in those with > 5 years of diabetic duration. The association of dry eye among uncontrolled was statistically highly significant with P value less than 0.001. The tear break up time was found to be ≤ 10 sec in 26 % (26/100). Schirmers test was found to be ≤ 10 mm in 27 % (27/100). Stains (Rose Bengal and fluorescein stain) were found to be abnormal in 18 %. Retinopathy was seen in 100 % of type I and 9.18 % of type II group. Statistically highly significant association was found between retinopathy and dry eyes (P < 0.001). CONCLUSIONS Diabetes and dry eye appears to have common association. Highly significant statistical correlation was found between retinopathy and dry eyes. Examination for dry eyes should be an integral part of the assessment of diabetic eye disease. KEY WORDS Diabetes, Dry Eye, Diabetic Retinopathy

Published: August 2021

BACKGROUND Aesthetic concerns have plagued humans for ages, but now modern technology and science have presented us with various options to treat these concerns. One such aspect is gingival depigmentation which as a dentist, we often come across. A randomized controlled clinical trial was conducted to compare and evaluate the techniques of gingival depigmentation for the management of gingival hyperpigmentation. METHODS A total of 45 patients with gingival pigmentation were randomly allocated into 3 groups: Surgical scalpel (N = 15), Cryosurgery (N = 15) and 810nm Diode Laser (N = 15). Melanin pigmentation index (MPI), visual analogue scale (VAS), wound healing index (WHI) and colour intensity index were evaluated for all the groups at baseline, immediate postoperative, 1 week, 1 and 3 months postoperatively. Statistical analysis was done for the data obtained to test the significance between the variables. P value < 0.05 was considered significant. RESULTS MPI scores from baseline to the postoperative intervals were effective in the management of gingival hyperpigmentation without any statistically significant difference. Faster healing was noted with surgical scalpel than cryosurgery. VAS scores were higher for the surgical scalpel group and lower for the other groups. The colour intensity index, an increase in the red colour value and decrease in the blue colour value was indicative of effectiveness of all the three techniques in the management of gingival hyperpigmentation. CONCLUSIONS It can be concluded that all the three techniques are effective in the management of gingival hyperpigmentation.

Published: August 2021

BACKGROUND Visual selection by using shade guides is the most common but also the most subjective technique, influenced by factors such as the age of the observer and eye fatigue. Digital imaging provides a practical and consistent method of determining tooth colour. A suitable alternative for DSLR cameras may be a mobile phone camera. Recent smart phones have manual control which helps to manually adjust parameters. Female patients usually use lipstick, which may alter the tooth colour perception, but there is no clinical evidence showing the effect of lipstick on tooth shade. The purpose of this study was to evaluate the reliability of using phone camera and the effect of lipstick on the shade of the tooth. METHODS This study was conducted on 11 female individuals within the age of 18 - 25 years. Eight photographs were made of all 11 participants, using 3 different smart phone cameras and Nikon D3400 DSLR camera with twin flash and cross-polaroid filter was used as the control group. The parameters of all the cameras were standardized for every image. All digital photographs were evaluated with a Digital Colour Meter software, which gave the parameters in the RGB colour codes and CIE L, a*b* colour space. RESULTS There was no statistically significant difference in the L* and R* values between the control and the smartphone camera groups. There was no statistically significant difference in L* and R* values before and after applying lipstick in all the groups. There was no significant difference in L* and R* values in all the groups before and after applying lipstick. CONCLUSIONS Recent smartphone cameras with manually adjusted parameters including unprocessed or RAW images can be used as a reliable tool for shade matching. Shade matching can be done even after applying lipstick, as there was no difference seen in this study. KEY WORDS Esthetics, Shade, Lipstick, Spectophotometer, Shade

Published: August 2021

BACKGROUND Increased accumulation of dental plaque and inflammatory response during treatment is due to the appearance of new retentive places around the components of fixed appliances attached to the teeth. During bonding procedures, there is certain amount of adhesive left on the tooth surface invariably around the margins between bracket and enamel interface called excessive adhesive flash (EAF), which may act as a plaque retentive area. We wanted to evaluate and compare the effect of EAF formed from two different orthodontic bonding adhesives on clinical periodontal status of patients undergoing fixed orthodontic appliance therapy. METHODS 20 patients indicated for treatment with fixed stainless steel preadjusted edgewise appliance were selected for the study. A split mouth design was followed where each patient’s teeth were divided into 2 groups; Group A: Teeth of right side bonded with non-tooth coloured orthodontic adhesive resin (Transbond XT Plus) – 1st and 4th quadrants; Group B: Teeth of left side bonded with tooth-coloured orthodontic adhesive resin (Transbond XT) - 2nd and 3rd quadrants. Clinical periodontal status was assessed by measuring Muhlemann modified papillary bleeding index, Turesky Gilmore Glickman modification of Quigley Hein Plaque Index, and a modification of the Orthodontic Plaque Index, before bonding (T0) and 1 week after bonding the appliance (T1). RESULTS Readings at T1 had significantly increased compared to T0 indicating increased plaque retention. However, difference between the indices for both groups at T1 was not statistically significant. CONCLUSIONS The excessive adhesive flash is a site for increased plaque accumulation, irrespective of the composite being tooth coloured or non-tooth coloured. KEY WORDS EAF, Adhesives, Split Mouth

Published: August 2021

BACKGROUND There is a worldwide scarcity of cadaver for teaching as well as for research. Many private as well as government medical colleges relay only on unclaimed bodies, but this scarcity of cadaver cannot be replenished with the unclaimed bodies alone. Despite the importance of body donation for medical education, cadaveric donation remains suboptimal worldwide. Body donation programs are still in their infancy in our country. The success of these programs depends upon the ability of our health care professionals in motivating the society at large. Thus, it is crucial that our medical fraternity and health care professionals themselves support and favour this issue. Hence this study was carried out to know the attitude of medical fraternity towards body donation program. METHODS A cross-sectional survey was conducted among the faculties of Jawaharlal Nehru Medical College, Sharad Pawar dental college and Ayurvedic college at Datta Meghe Institute of Medical science, Sawangi Meghe, Wardha. Study duration was from July 2018 to July 2019. Inputs from all the study participants were obtained on the basis of questionnaire about the attitude towards body donation after taking their consent. The questionnaire was collected from the participants’ and the data obtained was assessed statistically. RESULTS The study revealed significant negative attitude of medical fraternity towards body donation. It was observed that 21.7 % male & 3.7 % female faculties from medical colleges, 11 % male and 5.71 % female faculties from dental colleges and 25 % male and 10 % female faculties from Ayurvedic colleges were willing for body donation whereas 96 % of faculties from medical colleges, 92 % from dental colleges and 89 % ayurvedic faculties were not willing to donate their bodies for dissection purpose because they had an awful experience in the dissection hall. They had witnessed the dishonoured condition of the cadaver in dissection hall. 95 % of faculties from medical college, 92 % dental faculties and 90 % ayurvedic faculties stated that to get dissected on the table was an atrocious feeling. CONCLUSIONS The success of body donation programs depends upon the ability of health care professionals in motivating the society for voluntary body donation. Negative attitude of medical fraternity towards body donation may interfere with this role. Developing the practice of respecting and honouring the cadaver, from the very beginning of the career will help to change the attitude of medical graduates towards body donation. Competency no AN82.2 from volume 1 UG curriculum, module no 1.5 from ATCOM module may help to change the attitude of budding doctors.

Published: August 2021

BACKGROUND Ameloblastoma is a rare, benign odontogenic neoplasm which is locally aggressive and mostly present with a painless swelling. The enigma about the diagnosis of proliferative ameloblastoma and ameloblastic carcinoma is still a debate because the diagnostic criteria is not standardized or quantified which has a direct correlation on its biological behaviour and prognosis. Despite numerous studies, correlation between the histological patterns of ameloblastoma and tumour behaviour has not been consistently established. The present study was done to compare the expression levels of Ki-67 between conventional ameloblastoma, proliferative ameloblastoma and ameloblastic carcinoma and to assess the usefulness of these markers for diagnostic differentiation. METHODS A retrospective study of total of 18 cases of ameloblastoma were retrieved from the archives of Department of Oral and Maxillofacial Pathology, Saveetha Dental College from 2012 till 2019, which included conventional ameloblastoma, proliferative ameloblastoma and ameloblastic carcinoma. Immunohistochemical (IHC) analysis was done using the marker Ki-67 and labelling index were determined for the same. RESULTS The results of the current study showed that the cellular proliferative activity assessed using Ki-67 in follicular ameloblastoma was (55 %), 4 cases of plexiform ameloblastoma (22 %), 17 % of proliferative ameloblastoma and 6 % of ameloblastic carcinoma showed negative expression. CONCLUSIONS Immunophenotyping using the marker Ki-67 may be a useful tool for histological typing of ameloblastoma. KEY WORDS Ameloblastoma, Ki-67, IHC, Immunophenotyping

Published: August 2021

BACKGROUND Advances in root canal instruments have led to lesser frequency of dentinal crack formation. Not many studies have been reported in literature that compare crack formation using instruments based on control memory (CM) and M wire technology. The study intended to evaluate and compare the prevalence of dentinal cracks formed by ProTaper Next (Dentsply Maillefer, Ballaigues, Switzerland), HyFlex CM (Coltene, Whaldent) and Wave One (Dentsply, Maillefer) reciprocating file systems at the apical and middle third of the mesiobuccal root canal of mandibular molars under scanning electron microscope (SEM). METHODS Forty-five extracted sound human mandibular molars were decoronated and mesial roots were retained followed by root canal instrumentation using ProTaper Next, HyFlex CM and WaveOne reciprocating files. Roots were then sectioned perpendicular to the long axis of teeth and viewed under scanning electron microscope to detect the presence of cracks. RESULTS ProTaper Next system produced more cracks compared with HyFlex and Wave One (P < 0.05) but there was no statistically significant difference between all the three groups. All the file systems showed more incidences of cracks in the apical third compared to middle third. CONCLUSIONS All the NiTi instruments produced cracks and the highest incidence of cracks was seen in the apical third compared to middle third region.

Published: August 2021

BACKGROUND The present study was taken up to study the clinical manifestations, complications, and outcome in patients with poisonous snake bites admitted to Vivekanand Hospital, Latur (Maharashtra). METHODS This was a longitudinal study. Adult snakebite patients admitted from December 2012 to November 2014 were studied. RESULTS Mostly males (71.4 %) in the age group 18 - 29 years (58.6 %) were affected. Farmers (71.4 %) in rural areas (87.1 %) are the major sufferers. The neurotoxic venom poisoning ptosis (100 %) was commonest manifestation and was found in all cases. Palatal and pharyngeal palsy, ophthalmoplegia, respiratory palsy were also seen. In hemotoxic poisoning, bleeding from the bite site (73 %) was the commonest manifestation followed by hematuria (48.6 %) and gum bleeding (24.3 %). Among complications of poisonous snakebites, cellulitis (86.5 %) was the most common followed by acute renal failure (47.6 %), disseminated intravascular coagulation (DIC) (23.8 %), respiratory paralysis (12.7 %) and shock (4.28 %). Adverse reactions to anti-snake venom (ASV) were noted in 16 (22.9 %) patients. Total 10 patients died (14.3 %) mostly were due to acute renal failure (26.6 %). CONCLUSIONS Snakebite is common among agricultural labourers. Mostly males in the age group 18 - 29 years were bitten during 12 noon to 6 pm. Peak incidence peaked in between May to October. Viper bites were more common than Elapidae in this study. In neurotoxic envenomation, ptosis was the commonest and earliest symptom while in hemotoxic envenomation, most common symptoms were bleeding from bite site and hematuria. The commonest complications were cellulitis, acute renal failure and DIC. Early hospitalization and timely ASV were the corner stone in the treatment of snakebite.

BACKGROUND Achieving profound pulpal anaesthesia with an inferior alveolar nerve block (IANB) in lower molars suffering irreversible pulpitis is difficult and quite challenging. In many instances, supplemental anaesthesia is required during endodontic therapy. The present study was done to evaluate the efficiency of 2 % lidocaine and 4 % articaine comparatively, as an inferior alveolar nerve block (IANB) and supplemental infiltration buccally in providing complete mandibular molar anaesthesia. METHODS This is a randomized double-blinded study. Sixty patients were categorized randomly into test group (n= 30) and control group (n= 30). Patients in the test group were anaesthetized with 4 % articaine (1:100,000 epinephrine dilution), and those in the control group were anaesthetized with 2 % lidocaine (1:80,000 epinephrine dilution). The Heft-Parker visual analog scale (HP-VAS) was utilized for rating patient’s pain during the treatment procedure. In case of pain after IANB, a supplemental buccal infiltration was given with the same anaesthetic used for IANB. Complete pain absence or mild pain was regarded as an anaesthetic efficacy, and moderate to severe pain was regarded as an anaesthetic failure. Recorded data was analyzed using the chi-square test and two proportion Z test. The set significance level was 0.05. RESULTS After an IANB, observed anaesthetic success was 56 % in the articaine (test) group and that in the lidocaine (control) group was 33 %. After buccal infiltration, it was 92 % in the articaine group and 75 % in the lidocaine group. The difference was not found significant between the two groups statistically following IANB and infiltration buccally. The overall success of articaine was 96 %, and lidocaine was 83 %. CONCLUSIONS Compared to 2 % lidocaine, 4 % articaine was found more efficient in achieving profound pulpal anaesthesia in mandibular molars suffering irreversible pulpitis after IANB and buccal infiltration though the difference was insignificant statistically.

Authors: Bhise Dhondiba Haribhau
Published: August 2021

BACKGROUND Hypertension or elevated blood pressure is a serious medical condition, obstructive sleep apnoea (OSA) is an important identifiable cause of hypertension. Early identification and treatment of sleep disordered breathing contributes to prevention of hypertension, and treatment of OSA may improve blood pressure control as well. This observational study was done to demonstrate the association of sleepdisordered breathing with patients who have systemic hypertension. METHODS Total 94 patients were included in this study. Out of ninety-four patients, eleven patients had mild sleep apnoea, nine patients had moderate sleep apnoea, and twelve had severe sleep apnoea. RESULTS In mild OSA there were four patients with blood pressure < 120 / 80 mmHg while seven patients with blood pressure of 121 - 140 / 81 - 90 and there were four patients with blood pressure 141 / 91. In moderate OSA there were 9, 3, 6 and 1 patients in the group of blood pressure < 120 / 80, 121 - 140 / 81 - 90, > 140 - 160 / 91 - 100 and > 160 / 100 mmHg respectively. In severe obstructive sleep apnoea there were 5, 7, 6 and 2 patients in the group of blood pressure < 120 / 80, 121 - 140 / 81 - 90, 141 - 160 / 91 - 100 and > 160 / 100 mmHg respectively. The severity of hypertension is strongly associated with apnoea-hypopnea index (AHI). CONCLUSIONS This study shows a statistically significant association of hypertension with obstructive sleep apnoea and increased severity of hypertension associated with the increased severity of obstructive sleep apnoea hypopnea syndrome (OSAHS).

BACKGROUND A smooth zirconia surface is necessary to protect the opposing natural dentition, to prevent plaque accumulation and to increase the survival rate of restoration by reducing the chances of failure by crack propagation. Surface roughness can be incorporated by routine dental procedures done in labs and clinics to adjust the restoration. It is unclear which surface treatment is most appropriate to achieve clinically acceptable zirconia surface. The purpose of this study was to evaluate the effect of grinding and subsequent various surface treatments on the surface roughness of full contour monolithic zirconia. METHODS In this invitro study 10 zirconia bars of final dimensions 20 x 4 x 2 mm & 40 zirconia bars of final dimensions 20 x 4 x 2.2 mm were milled and sintered. The zirconia bars with final dimensions 20 x 4 x 2mm were glazed and selected as samples for control group (Group C) (n = 10). Forty zirconia bars with dimensions of 20 x 4 x 2.2 mm were grounded using a standard straight cylindrical diamond point (105 – 125 µm) by placing them in a customized grinding apparatus till the dimensions became similar to that of control group i.e. 20 x 4 x 2 mm. After grinding and confirming the dimensions of each full contour monolithic zirconia bar using digital vernier caliper, zirconia bars were randomly allocated into 4 groups with 10 samples in each group (n = 10), namely (Group G: Grinding only, Group G+R: Grinding & Reheating, Group G+G: Grinding & Glazing, Group G+P: Grinding & Polishing) respectively. Surface roughness values were measured using a profilometer. Differences between groups were examined using one-way analysis of variance (ANOVA) (P ≤ 0.05) and Post hoc Tukey HSD test was done for multiple comparisons of surface roughness in between the groups using Statistical Package for Social Sciences (SPSS) software. RESULTS Group C showed the least surface roughness values. The maximum surface roughness values were seen in Group G. Surface roughness of Group G, Group G + H and Group G + G were statistically significant from Group C and Group G + P. There was no statistically significant difference in surface roughness values between Group C and Group G + P. CONCLUSIONS It can be concluded that polishing after grinding significantly reduced the surface roughness and re-established the surface smoothness of full-contour monolithic zirconia bars.

BACKGROUND Addition of adjuvants to the neuro axial blocked helps prolongate the duration and quality of analgesia and anaesthesia. The safety and efficacy of drugs dexmedetomidine and neostigmine have been less commonly studied. We wanted to compare post-operative analgesia, haemodynamics, and side effects if any in this study. METHODS Combined spinal - epidural anaesthesia was performed in 60 patients who underwent lower limb surgeries of less than 2 hrs. The patients were given the drug epidurally post-surgery. Group I, II and III were given 10 ml of 0.25 % bupivacaine alone, with 1 microgram per kg of neostigmine and with 0.5 milligram per kg of dexmedetomidine and 1 microgram per kg of neostigmine, respectively. 50 mg tramadol intravenous was kept as rescue analgesic. Parameters which predict haemodynamics, assessment of pain, period of analgesia, demand for rescue analgesia and the chances of side effects were noted over the next ten hrs. RESULTS To conclude, epidural analgesia is the most preferred analgesia these days in management of lower limb orthopaedic surgery’s post-operative pain. When bupivacaine was combined with neostigmine and dexmedetomidine as a neuraxial adjuvant, it prolonged the post-operative analgesia significantly without increasing the side effects of those drugs. The combination of two drugs proved better than the use of single drug alone. CONCLUSIONS Combination of neostigmine and dexmedetomidine when used as a neuraxial adjuvant, significantly prolonged the duration of post-operative analgesia by 274.13 4.539 in lower limb orthopaedic cases compared to neostigmine alone that was 176.23 ± 3.441.

BACKGROUND Infertility is a multidimensional health problem with social and economic consequences. Infertility affects about 10 - 15 % of reproductive age couples. 1 Hysterolaparoscopy is safe and effective method to diagnose infertility. The purpose of this study was to determine the role of diagnostic hysterolaparoscopy in the evaluation of infertility in Chalmeda Anand Rao Institute of Medical Sciences. METHODS A prospective hospital-based study was carried out in Chalmeda Anand Rao Institute of Medical Sciences over a period of 1 year from August 2019 to July 2020. Hysterolaparoscopy was done in 100 patients. Women aged 20 - 40 years with normal hormone profile without male factor infertility were included. RESULTS 100 patients with infertility were undertaken, 70 (70 %) women had primary infertility and the remaining 30 (30 %) had secondary infertility. Ovarian pathology (30 %), endometriosis (23 %), tubal pathology (14 %) and pelvic adhesion (14 %) were the most well-known anomalies recognized in laparoscopy in both primary and secondary infertility. Uterine septum was major intrauterine pathology seen in two gatherings. Out of 12 patients having uterine malformations, most regular uterine malformation in both the gatherings was 9 uterine septum and 2 unicornuate and 1 was hypoplastic uterus. CONCLUSIONS Combined hysterolaparoscopy is a safe, effective, and reliable method in comprehensive evaluation of infertility. It helps in the diagnosis of pelvic pathology which is missed by routine pelvic examinations and basic investigations done for evaluation of infertility. Hysterolaparoscopy gives the added advantage of doing a therapeutic procedure in the same sitting. Thus, hysterolaparoscopy may be considered as gold standard and definitive investigative day-care procedure for evaluation of female infertility. KEY WORDS Hysteroscopy, Infertility, Laparoscopy
