ABSTRACT

Introduction
One of the main factors in the successful treatment of fixed prosthodontics is preparation of the teeth such that proper retention of the crown is provided. The aim of the study was to compare the convergence angle in full-crown abutment teeth prepared by the preclinic and senior students in the Faculty of Dentistry, Tabriz University of Medical Sciences, Tabriz, Islamic Republic of Iran.

Materials and methods
A cross-sectional/analytical study was conducted on dental students in the Faculty of Dentistry, Tabriz University of Medical Sciences, Tabriz, Islamic Republic of Iran in 2016. The sample size was determined randomly at n = 30 for each group. Preparation angle for each specimen was measured and recorded by digital photographs and Autocad software. The results were analyzed with appropriate statistical tests.

Results
The results showed that preclinic and senior students prepared the anterior teeth with average values of 22.13 ± 9.59 to 18.53 ± 8.87° and 18.46 ± 11.08 to 14.6 ± 6.32° respectively, from the buccolingual and mesiodistal aspects. Concerning posterior teeth, preclinic and senior students prepared them with average values of 21.4 ± 10.24 to 22.46 ± 8.99° and 19.46 ± 8.09 to 21.13 ± 8.83° respectively. Although the average value of convergence angle in both aspects was higher for preclinic students than for the senior students, t-test for independent groups revealed no significant differences (p > 0.05).

Conclusion
Either preclinic or senior students prepared the teeth with a convergence angle, i.e., higher than ideal. However, all the recorded angles were within the range of previous studies.

Published: July 2019

ABSTRACT

Aim
To assess the impact of removable partial denture (RPD) on the quality of life in patients wearing RPD after 1 year of use.

Materials and methods
Observational study was conducted on a convenience sample of 50 patients who were delivered RPD in the Department of Prosthodontics. Oral health impact profile (OHIP-14) (translated to Tamil, but not validated) was used to measure the impact. Data were collected using telephonic interview at 6 months after the insertion of RPD (T1) and (T2) at the end of 1 year (time interval of 6 months) prospectively. Significant differences for prevalence, mean OHIP-14 scores, and extent were determined using t test.

Results
Increase in mean OHIP-14 scores and extent was observed at T1 and T2. Almost all the dimensions of OHIP-14 had higher scores at T2 except psychological discomfort. Physical pain, physical disability, and psychological disability were dimensions with significant differences (p < 0.05). A fivefold increase in proportion was observed for physical disability and psychological disability among those reporting impacts as “very often/fairly often.”

Conclusion
The RPD had detrimental effect on wearer's quality of life with significant impact for painful aching in the mouth, feeling a bit embarrassed, and difficulty in chewing. Wearing RPD significantly increases the extent of impacts within a short time span of 6 months.

Clinical significance
The RPD can have a considerable impact on quality of life, which can either ameliorate or deteriorate. Patients have to be counseled periodically at subsequent recall visits and their quality of life measured, which will enable clinicians to rectify, assess, and provide adequate care to improve the overall quality of life.

Authors: Nayak Sangeeta U , Kamath Deepa G , Pai K Keshava 
Published: July 2019

ABSTRACT

Introduction
Diabetes mellitus is one of the key public health issues worldwide. Diabetes mellitus and its related oral manifestations, particularly in the form of poor periodontal health, has impact on physical health along with emotional and psychosocial consequences. The current study was done to assess periodontal health and its impact of on the quality of life among type II diabetics.

Materials and methods
A total of 138 diabetic subjects (test group) and 128 nondiabetic subjects (control group) were included in the study. Periodontal parameters, such as plaque index, gingival index, and community periodontal index of treatment needs (CPITN) index were recorded. Oral health impact profile (OHIP-14) questionnaire was used to evaluate effect of periodontal health on quality of life.

Results
Plaque index and gingival index scores were greater among test group, but were not statistically significant. The CPITN score was statistically significant when compared with control and test groups. When the mean of OHIP-14 scores was compared among two groups, five of the seven subdimensions were statistically significant. A statistically significant difference was found when overall total OHIP score was compared among control and test groups.

Conclusion
Overall oral health and observed oral healthrelated quality of life were lower among diabetic subjects in comparison with nondiabetics. Periodontal health was poorer and needs more attention among diabetic patients.

Authors: Gupta Lokendra , Aparna IN , Dhanasekar B , Bhat Sujatha , Agarwal Priyanka 
Published: July 2019

ABSTRACT

Aim
The aim of this study was to evaluate the antifungal activity of heat-activated denture base resins modified with different concentrations of methacrylic acid (MAA).

Materials and methods
Methyl methacrylate (MMA) monomer of heat-activated resins was modified with different concentrations of MAA (0, 15, 20, and 25%) for the preparation of specimens to evaluate antifungal activity of heat-activated resins. Prepared specimens were stored in distilled water at 37°C for 1 day and 1 week before the evaluation of microbial adhesion. Microbial adhesion of Candida albicans cells to acrylic samples was examined under light microscopy after Gram staining of all the acrylic samples. Data were subjected to one-way analysis of variance followed by post-hoc Tukey's honest significant difference test. A value of p < 0.05 was considered to be statistically significant

Results
Addition of MAA to the MMA monomer was found to significantly reduce the adhesion of C. albicans for all the groups. Reduction of C. albicans cell adherence was found significant for all three groups (I, II, and III) as compared to control, both at 1 day (p < 0.001) and 1 week (p < 0.001) after storage in distilled water

Conclusion
Addition of MAA to conventional denture base formulations reduced the adhesion of C. albicans. This method of incorporating antifungal property to denture base resins can effectively be used to reduce denture stomatitis in elderly and immunocompromised patients.

Published: July 2019

ABSTRACT

Aim
The aim of this study was to investigate the root and canal morphology of maxillary first and second molars in Southern West Coastal Indian population using cone beam computed tomography (CBCT).

Materials and methods
Cone beam computed tomography images of (n = 143) maxillary first molar and (n = 139) maxillary second molar were obtained from Southern West Coastal Indian population. The number of roots, root canals, and presence of second mesiobuccal (MB2) canal were determined.

Results
Two roots were seen only in 1.4% of first molars and 8.6% of second molars. Three- rooted were the most common and seen in 98.6% of first molars and 89.9% of second molars. Single root was seen in 1.4% of second molars. The incidence of MB2 canal in the first molar is 64.1% and in second molar 23%. C-shaped canals were found in 1.4% of the second molars

Conclusion
Southern West Coastal Indian population showed features that were similar to other regions of Indian Population. The CBCT is a wonder tool for the study of root canal morphology and a reliable source of information for retrospective studies.

Diagnostic Panel of Markers CD45, CD20, CD3, CD138, and CD56 for Oral Solitary Plasmacytoma of Bone
Authors: Abraham Marin , Sagar Parimala 
Published: July 2019

ABSTRACT

Aim
The present case aims to emphasize on the role of immunophenotyping in plasmacytic malignancies.

Introduction
Solitary plasmacytoma of bone (SPB) is a rare entity often encountered in vertebrae and less frequently in long bones. Its presence in jaws is extremely rare, accounting for 4.4% of cases only. About 5% of patients with plasma cell dyscrasias present with SPB.

Case report
An elderly male patient reported with a chief complaint of growth in the anterior region of the lower jaw since 3 months. The histopathological features following an incisional biopsy were suggestive of pyogenic granuloma. Serological investigations revealed seropositivity for human immunodeficiency virus (HIV)-1 antibody with hypergammaglobulinemia and hypoalbuminemia. Histopathology of excisional biopsied tissue revealed a round cell malignancy with plasmacytic morphology. Further, to arrive at a specific final diagnosis, immunohistochemistry (IHC) was employed with a panel of markers CD45, CD20, CD3, CD138, and CD56. This panel enabled us to establish a final diagnosis of SPB with clinicopathologic correlation.

Conclusion
The present case posed a diagnostic dilemma as it presented with overlapping features of non-Hodgkin's lymphoma (NHL), multiple myeloma (MM), extramedullary plasmacytoma (EMP), and plasmablastic lymphoma (PBL). A thorough clinical, radiological, serological, and IHC panel helped to diagnose the present case. The CD56 enabled differentiation between SPB and PBL. Thereby, this article emphasizes on the need for a panel of IHC markers that permit definitive diagnosis of lymphopoietic malignancies.

Clinical significance
Timely diagnosis of malignant lesions is an essential concern for effective management. Thus, we emphasize that the IHC is a valuable investigative tool in the diagnosis of round cell tumors with plasmacytoid morphology.

Published: July 2019

ABSTRACTBackgroundGestational age estimation is one of the most important information conveyed by a sonologist when performing an obstetric ultrasound examination. The traditional fetal biometric parameters, such as biparietal diameter (BPD), head circumference (HC), femur length (FL), and abdominal circumference become increasingly unreliable for accurate gestational age estimation with advancing pregnancy, especially in 3rd trimester. This study was conducted to assess the role of fetal kidney length (KL) as an alternate parameter to assess gestational age in 2nd and 3rd trimesters.AimTo assess relationship between sonographic gestational age and fetal KL between 18 and 39 weeks of gestation.Settings and designProspective, cross-sectional, single operator study conducted over a period of 1 year in a medical college hospital.Materials and methodsThree hundred singleton pregnant women between 18 and 39 weeks of gestation were subjected to antenatal ultrasound. In addition to routine fetal biometry, measurements of fetal KL were made by noting distance between upper and lower poles of each kidney on a sagittal section of the fetal abdomen. The right and left KLs were averaged to obtain a single value for the purpose of statistical analysis.Statistical analysisStatistical analysis is done using SAS 9.2, SPSS 15.0, Stata 10.1, Med Calc 9.0.1, Systat 12.0, and R environment version 2.11.1. Fetal KL was expressed as mean ± standard deviation. Linear regression analysis was used to establish a relationship between sonographic gestational age in weeks and fetal KL. Level of significance was expressed as p value.ResultsA strong statistical correlation was found between sonographic gestational age and fetal KL. Nomograms and growth curves were constructed to correlate gestational age with fetal KL.ConclusionFetal KL measurements can be used as alternate method of estimating gestational age in women with uncertain last menstrual periods (LMPs) and presenting late in the gestation for safe confinement. In fetal macrocephaly, hydrocephalus, short-limb dysplasias, and when fetal head is engaged, these measurements are valuable alternate parameters to assess gestational age since they are simple, not time-consuming, easy to identify, and measure.How to cite this articleHemraj S, Abraham SM, Acharya D, Ravichandra G, Vinayaka US.

ABSTRACTAimTo evaluate the role of hysteroscopic endometrial injury and its timing prior to embryo transfer in patients undergoing IVF (in vitrofertilization) treatment.Materials and methodsA total of 133 patients who underwent hysteroscopy at CIMAR Fertility Centre at Kochi, between January 2013 and December 2014, and had normal hysteroscopic findings were enrolled for the study. These women subsequently underwent IVF treatment and were evaluated in three groups based on the timing of hysteroscopy before embryo transfer: Group I – hysteroscopy performed 50 days or less before embryo transfer (n = 54), group II – hysteroscopy performed between 51 days and 6 months of embryo transfer (n = 45), and group III – hysteroscopy performed more than 6 months before embryo transfer (n = 34).ResultsThe implantation rates were 21.8, 22.6, and 21.6% in groups I, II, and III respectively. Overall pregnancy rates were 44.4, 48.9, and 44.1%. Clinical pregnancy rates (CPR) were 40.7, 46.7, and 44.1% and live birth rates (LBR) were 30, 29, and 26% in groups I, II, and III respectively. Thus the implantation rate, overall pregnancy rate, and CPR were not significantly different in the three groups.ConclusionHysteroscopic endometrial injury prior to IVF does not improve the pregnancy rate in patients with normal hysteroscopic findings.Clinical significanceDue to the lack of definitive evidence regarding the role of hysteroscopic endometrial injury, ideal technique, and its timing prior to embryo transfer, it is necessary to evaluate the role of endometrial injury as a fertility treatment in women undergoing assisted reproductive technology (ART) cycles, as well as to present it in a way that supports clinical practice. At this stage, there is little evidence to support hysteroscopic endometrial injury prior to embryo transfer as a standard of care, and its use should be limited to selected cases after careful deliberation between the medical team and patient.How to cite this articlePillai A, Parasuram G, Thalakottoor FL, Gopinathan KK.

Severe Early-onset Ovarian Hyperstimulation Syndrome following Use of GnRH Agonist Trigger along with Low-dose hCG
Authors: Muthukumar K , Aleyamma TK , Thomas Sumi 
Published: July 2019

ABSTRACTControlled ovarian hyperstimulation, which is a key component of assisted reproductive technology (ART) treatment, can be excessive in certain cases and can lead to massive cystic enlargement of the ovaries and biochemical changes, leading to ovarian hyperstimulation syndrome (OHSS). Traditionally, human chorionic gonadotropin (hCG) has been used as ovulation trigger in ART cycles but its sustained luteotrophic effect is associated with an increased risk of OHSS in high-risk patients. Gonadotropin-releasing hormone (GnRH) agonist trigger can be used as an alternative to hCG in GnRH antagonist downregulated cycles. However, the use of GnRH agonist was associated with a lower pregnancy rate due to deficient luteal phase, and hence, use of low-dose hCG to rescue the deficient luteal phase has been used. Various studies showed that using lowdose hCG did not increase the risk of OHSS even in high-risk patients. Here, we present a case report of severe early-onset OHSS following GnRH agonist trigger with low-dose hCG.How to cite this articleThomas S, Kamath MS, Muthukumar K, Aleyamma TK.

Authors: Sharma Arpit , Dabholkar Jyoti , Virmani Nitish 
Published: July 2019

ABSTRACT

Introduction
Benign vocal cord lesions cause significant dysphonia by disrupting the normal vibratory function of the vocal fold mucosa. Multidimensional assessment of voice characteristics allows for an accurate analysis of voice impairment and can be used to assess the outcome of different treatment modalities.

Aims
To evaluate the outcome in patients treated for benign vocal fold lesions using multidimensional voice assessment

Materials and methods
Thirty adult patients with benign vocal fold lesions were treated according to standard protocols and followed up for 6 months. Voice was evaluated by visual analog scale (VAS), GRBAS (grade, roughness, breathiness, asthenia, strain) scale, maximum phonation time (MPT), S/Z ratio, and acoustic parameters using PRAAT. Pre- and posttreatment voice was compared.

Results
Benign lesions observed were vocal polyps (16), vocal nodules (7), vocal fold cysts (5), vocal cord papilloma (1), and sulcus vocalis (1). Mean VAS rating improved from 7.5 to 2 at 3 months and 1.6 at 6 months. Mean GRBAS score improved from 7.5 to 2.96 at 3 months and 2.3 at 6 months. Maximum phonation time increased from 9.43 seconds to 14.16 seconds at 3 months and 14.46 seconds at 6 months. S/Z ratio reduced from 1.37 to 1.16 at 3 months and 1.15 at 6 months. Jitter reduced from 1.81 to 1% at 3 months and 0.97% at 6 months; shimmer decreased from 6.07 to 2.19% at 3 months and to 2.03% at 6 months. Harmonic-to-noise ratio values improved from 8.01 to 10.78 dB at 3 months and 10.96 dB at 6 months; mean F0 increased from 207.27 to 217.89 Hz at 3 months and 219.65 Hz at 6 months.

Conclusion
A single measurement of voice cannot be used as a reliable outcome measure. Perceptual, aerodynamic, acoustic, and self-analysis together allow a multidimensional assessment of voice characteristics.

Dentoskeletal Effects of the Modified Tandem Appliance vs the Facemask Appliance in the Treatment of Skeletal Class III Malocclusion: A Single-center, Randomized Controlled Trial
Authors: Husson Amro H , Burhan Ahmad S , Salma Fadwa B , Nawaya Fehmieh R 
Published: July 2019

ABSTRACT

Aims
The aim of this randomized controlled trial was to compare the skeletal and dentoalveolar effects of the modified tandem appliance (MTA) vs the facemask (FM) with rapid maxillary expansion.

Materials and methods
Thirty-two patients, aged 7 to 9 years were recruited. Eligibility criteria included skeletal class III malocclusion that resulted from the retrusion of the maxilla. Randomization was accomplished to divide the sample into two equal groups to be treated with either MTA or FM. Lateral cephalometric radiographs were obtained before treatment and after 2 mm positive overjet was achieved. Intragroup comparisons were performed using paired-sample t-test, and intergroup comparisons were performed using two-sample t-test at the p ≤ 0.05 level.

Results
Thirty-two patients (16 in each group) were available for statistical analysis. The pretreatment variables of both groups were similar. Both treatment therapies showed similar significant increase in the SNA and ANB angles, accompanied by slight decrease in the SNB angle. The increase in the SN:GoMe angle, Bjork's sum, and the overjet were significantly greater in the FM group. The forward movement of upper dentition was similar in both groups. Although the lower incisors retrusion was significantly greater in the FM group than in the MTA group, the uprighting of the lower molars was significantly greater in the MTA group.

Conclusion
Both appliances showed similar effects apart from less clockwise rotation of the mandible, less retrusion of the lower incisors, and greater uprighting of the lower molars in the MTA group.

Clinical significance
Both the MTA and the FM groups are effective in treating class III malocclusion. The MTA group is more efficient in controlling the clockwise rotation and gaining some space in the lower arch.
