Published: July 2023

ABSTRACT

Introduction:
An instrumented and endodontically treated tooth may sometimes impede disinfection by trapping hard tissue as well as the other canal contents at the isthmus level of the canal. Thus, the current in vitro study was piloted to assess the competence of two irrigating systems.

Methods:
Twenty mandibular with two mesial canals convergent into a single foramen and joined by an isthmus of the human permanent teeth were compared for the two irrigation systems of continuous and intermittent ultrasonic (US) motions of the irrigation. The teeth were prepared by a single rotary system and were imaged using the “Scanning electronic microscopy-SCM”. The parameters were compared before and after the irrigation of the canal with the intended US systems for the removal of hard tissue debris. The appropriate statistical tools were used to find the significance, the value of which was kept at P < 0.05.

Results:
Significant percentage reduction of the hard tissue debris was achieved after the application of the supplemental irrigation protocols (P < 0.05). However between the groups, there was no significant difference.

Conclusions:
Comparable removal of the hard tissue debris was obtained in both the irrigation systems. Though not significant, the GentleWave performed better than the Irrisafe.

ABSTRACT

Introduction:
In edentulous individuals, single implant-retained mandibular overdentures are an effective substitute for double implant-retained overdentures. In this current research, the oral health-related quality of life (OHRQoL) was assessed for the immediate loading overdenture using the implants. The comparisons are drawn between the single and double implants.

Materials and Methods:
Forty subjects received single and double implants for the placement of the mandibular overdentures. Within a week days of implant insertion, they were loaded with overdentures. Using the Oral Health Impact Profile-14 (OHIP-14) questionnaire, the OHRQoL was measured before treatment, one month following treatment, and 12 months thereafter.

Results:
In both the single implant and double implant groups, participants’ mean OHIP-14 scores decreased statistically significantly for the different timelines. For the single implant group, the baseline total mean OHIP-14 score was 14.33, and for double implants, it was 19.15. Following therapy, it decreased to 8.55 in the single implant group and 9.48 for the double implant group at one month, and at 12 months, it further decreased to 3.25 in the single implant group while it was 5.15 in the double implant group.

Conclusions:
Single and double implants increase the QoL for older subjects who are edentulous at the 1-month and 1-year recall points. When two implants are used by older individuals, the single implant might offer an equivalent quality of life.

ABSTRACT

Introduction:
With the advent of mini-implants, Class II correction has become routine. The study’s goal was to compare the “Bone-Anchored Pendulum Appliance (BAPA)” to the “Bone-Anchored Intraoral Bodily Molar Distalizer (BAIBMD)” in terms of clinical efficacy.

Materials and Procedures:
Five boys and five girls were among the 10 patients in this split-mouth trial who had to have their molars distalized. On one side, BAPA Construction, and on the other, BAIBMD was piloted. A titanium mini-screw was used to secure both appliances to the bone since this was a spilled-mouth technique. The first molar bands to apply 200 g of force were used for both devices, as with all the other components that were similar for both appliances. For both sides, the nature, duration, and rate of tooth movement were compared. Using the Wilcoxon signed-rank test, descriptive statistics for several parameters were examined.

Results:
Distalization was accomplished on both sides with clinical success. The rate of distalization did not show any significant variation. Less time was needed for distalization with BAPA, as evidenced by the statistically substantial variances in treatment duration between the two groups. Molar tipping was noticed in BAPA, and it was statistically significant.

Conclusion:
While the pace of distalization was equal for both appliances, BAIBMD required more time than BAPA but resulted in a distal tooth movement that was mostly translatory in nature.

ABSTRACT

Introduction:
The orthodontic appliances have been known to accelerate enamel loss due to various reasons. Since there are few studies supporting the role of the nano-HAP in the mineralization of the demineralized tooth surfaces, the current study compared nano-HAP’s capacity to remineralize the demineralized enamel layer surrounding braces at various concentration levels.

Materials and Procedures:
This investigation involved 60 healthy permanent premolars that had just been excised. All specimens had 3M-Unitek brackets glued to their buccal surfaces. The samples were artificially demineralized and divided into three groups. The control group, Toothpaste ApaCare, and ApaCareTM varnish. Before and after remineralization, selected samples from each group were analyzed using a “Scanning Electron Microscope (SEM)” and evaluated using “Energy Dispersive X-Ray Analysis (EDAX).” Spectrometer and profilometer were used for the study of surface and the color. Statistics were used to analyze the outcomes. The threshold for significance was fixed at 0.05.

Results:
After remineralization by nano-HAP, there was a significant rise (P < 0.001) in both calcium and phosphorus levels. This was picked up by EDAX, and SEM verified it. When compared to the control group, the nano-HAP application greatly improved the color measurements in the study groups (P < 0.001), and it also resulted in a significant decrease in surface roughness (P < 0.001).

Conclusion:
Our study’s results showed that nano-HAP could be successful in restoring demineralized enamel around brackets, reducing the surface roughness and color of the enamel surface.

ABSTRACT

Introduction:
In many oral procedures that involve the implants, hair implantations, “Platelet-Rich Fibrin Membrane (PRF)” is commonly applied. The advantages are many. In this study, the mechanical resistance of PRF under resistance pull on a longitudinal axis was assessed and compared.

Material and Methods:
For the current in vitro study, 60 volunteers donated each 10 ml of their blood and hence a total volume of 600 ml of blood was procured that was analyzed for the current study. The total volume was grouped to three groups where they receive three resistance centrifugation forces of “F-200,600,800 m/s².” In each group, 20 samples were tested for each level of the G-resistance. Each group was further divided as two subgroups of different times of wait, where they were centrifuged at baseline time and after a stand of 30 minutes. On universal testing equipment, the PRF membranes were mechanically tensioned in order to determine each membrane’s resistance force. These values were compared for any statistical variance using appropriate statistical tools keeping P < 0.05.

Results:
Any applied force had no statistically significant effect on the centrifugation duration for membrane resistance. When the resistance was applied for the PRP samples immediately after they were procured, no significant variation was seen at all the grades of the centrifugation forces; consequently, the T30 group showed a statistically significant variance for the centrifugation forces applied (P = 0.04), with the highest value when the greatest force was applied. According to the results, the centrifugation waiting period could be determined based on the application requirement.

Conclusion:
For immediate membrane usage, the centrifugation had no effect on resistance; however, after 30 minutes, a membrane with greater resistance was produced by applying more force.

Published: July 2023

ABSTRACT

Introduction:
“Burnout syndrome (BS)” is a work-associated condition which is frequently observed in medical professionals, especially students. Extra-curricular activities (ECAs) are one of the coping techniques that students employ to deal with stress and exhaustion.

Goal:
The study’s goal is to evaluate dental students’ levels of burnout and how it correlates with their participation in ECAs.

Materials and Procedures:
In South India, a dentistry school conducted a cross-sectional questionnaire research with its students. Both the regular and supplemental batches of students from the first year through the fifth year (internship) were included. The “Maslach Burnout Inventory Student Survey”, which has 15 items in three areas—”Emotional Fatigue (EE), Cynicism (CY), & Professional Efficacy (PE)”—was used to assess burnout. A 5-point Likert scale was used to grade each response. Poisson log linear model and the Mann–Whitney U test were employed. The threshold for statistical significance was 5 out of 100.

Results:
Four hundred participants were finalized after the criteria. Over 80% of the participants were women students as in accordance with the routine proportion of the dental students. The participants’ average age was 22.1 ± 12 years. Burnout was seen in nearly 20% of subjects. Significant variation was seen for all the three domains of the burnout when they were compared against the ECA (P = 0.019(EE), 0.003(CY), and 0.005(PE)).

Conclusion:
It is safe to say that among the participants, burnout is a common occurrence. There is a need for early detection of burnout in dental students and prompt, efficient management.

ABSTRACT

Background:
In the clinical practice, one of the most common suspicious lesions that may be potentially malignant is oral leukoplakia. Globally, the rate at which it turns malignant varies. This study examines the levels of markers CD138 and 43 in oral leukoplakia.

Materials and Methods:
Twenty archival blocks of confirmed epithelial dysplasia were taken from the Department of Oral Pathology. These were processed for the identification of markers CD138 and 43 through Immuno Histo Chemistry (IHC). The blocks were divided equally for both the markers.

Results:
There was a noticeable difference in staining intensity between dysplastic tissue and nondysplastic epithelium. However, CD138 expression was low or weak in dysplastic epithelium. CD43 expression was negative in all nonhematopoietic tissues.

Conclusion:
Genes that are cancer associated have been found to have incredibly different impacts in numerous tissues during the multistep process of oral carcinogenesis. In tissues undergoing dysplastic changes, CD138 expression was shown to be decreased, which could point out the malignant changes initiated in the epithelium of the oral tissues.

Published: July 2023

ABSTRACT

Introduction:
The palatal rugae may alter their shape based on the various physical pressures that they had to endure. This study’s objective is to assess the various alterations in the palatal rugae parameters among the complete denture wearers.

Materials and Procedures:
Forty subjects in all were chosen for the study. The control group interventional groups had an equal number of participants who were further equally distributed based on gender. For all of the participants, mucostatic maxillary alginate imprints were taken, and gypsum castings were created. They were called at the scheduled intervals of 2, 6, and 12 months following the treatment. The models used during those recalls and all of the palatal rugae were examined under a microscope for quantity, length, form, orientation, and unifications. The unpaired t-test was used to statistically examine palatal rugae alterations.

Results:
Following the wear of the dentures, the experimental group’s primary, secondary, and fragmented rugae all gradually shrank in length. In terms of statistics, the alteration solely affected primary rugae and was significant (P < 0.001). After a year of wearing dentures, a minimal change in rugae’s form was noticed in the denture groups, but it was statistically not substantial (P > 0.05).

Conclusion:
Due to the prolonged mechanical stress the dentures placed on the palatal rugae, complete denture users saw a significant reduction in the length of their primary rugae. Rugae number, orientation, and unification were among the other criteria that did not change during the course of the study. Analysis of the palatal rugae may not be useful in identifying people wearing full dentures. However, in forensic investigations, rugae may act as an adjunct to other methods like fingerprints and DNA analysis.

Authors: Dutta Smita D. 
Published: July 2023

ABSTRACT

Introduction:
The practice of removing root canal fillings with solvent materials is frequently required to help an irrigation solution enter the tubules. The current research was aimed at assessing the antifungal properties specifically the candida albicans of the various solvent materials used for the gutta-percha (GP) material.

Materials and Methods:
Current research was aimed at as a lab method using the disk diffusion technique where the zone of inhibition (ZOI) was calculated. The materials that were analyzed were: orange oil, xylene, turpentine oil, chloroform, and eucalyptus oil. Candida albicans was the test organism employed in the investigation. The agar plates were covered with approximately 500 μL of the suspension. The sterile and empty disks were impregnated with 10 μL of pure GP solvents. These plates were incubated for one day at room temperature. The ZOI’s mean diameters were calculated for all five materials and quantified each solvent’s fungicidal activity. For intergroup comparison, ANOVA was utilized. P values < 0.05 were deemed substantial.

Results:
The maximum inhibition exhibited by the Eucalyptus Oil it was 19.01 ± 1.02 mm. This was followed by Xylene. The other three solvents Chloroform, Orange Oil, and Turpentine Oil exhibited a similar ZOI. When all the solvents were compared there was a significant variance of P < 0.001. However, there were significant variances for the Eucalyptus Oil and the Xylene to all the other solvents P < 0.001.

Conclusion:
This investigation showed that, in comparison to other solvents, the use of eucalyptus oil considerably reduced the levels of Candida Albicans.

Published: July 2023

ABSTRACT

Introduction:
Large chunks of the tissue are sacrificed during the surgical procedures for the treatment if oral cancers. Our goal was to assess the viability of “Buccal reconstruction using the anterolateral thigh (ALT) flaps, platysma myocutaneous (PM), and radial forearm free (RFF)”.

Material and Methods:
Sixty subjects were included in this investigation, and they were divided into 3 groups. The follow-up as accompanied for six months. Comparisons were made for the time for the operations, reduction in the width of the mouth opening and the survival rates of the flaps. The data that was collected for the above two parameters and compared for the significance using the ANOVA, keeping P < 0.05 as significant.

Results:
In the subjects with the PM, the width of the mouth opening reduced comparatively greater than that of the subjects who received other two flaps. The reduction in the mouth opening in the PM was significantly greater compared to that of the ALT and RFF. Survival was greater for the groups ALT and RFF compared to PM. Time of the surgery was the greatest for the ALT and least for the PF.

Conclusion:
The observations point to the fact that the PF requires more time than that of the other two flaps. The survival was however better for the ALT and RFF. Further research is suggested for suggesting an appropriative flap design.

Published: July 2023

ABSTRACT

Background:
To pursue further education in a particular specialty of dentistry, it is important for dental students to be aware of the “expectation” associated with any specific specialty in dentistry. Therefore students ‘attitudes’ towards ‘expectations’ of various specialties, to a large extent enables a meaningful understanding that facilitates appropriate planning in the dental sector for the community.

Materials and Methods:
A cross-sectional questionnaire based survey was conducted, which included, final year and dental interns studying in two dental institutions, in the State of Puducherry. It consisted of 27 questions that were graded using 5-point Likert scale. The responses for the attitude questions toward selecting Public Health Dentistry for post-graduation were categorized into three factors, negative attitude (includes score 0-21), neutral attitude (score 22-44), and positive attitude (score 45-64). Differences between groups were examined using t-test for proportions. The level of statistical significance was set at p < 0.05.

Results:
Among 221 respondents, 73 (33.0) were males and 148 (67.0) females. About (52.2%) of the respondents had positive attitude toward selecting Public Health Dentistry as their future career and (76.7%) had neutral attitude, around (5 %) had negative attitude towards the speciality for pursuing post-graduation in both the two institutions.

Conclusion:
Our study could highlight many factors namely gender, year of study etc which influence the attitude of students for selecting PHD as career choice. These specific factors could be kept in mind while course planning for government or private institutions so that maximum interest can be fetched among students.

Authors: Al Ghwainem Abdulhamid 
Published: July 2023

ABSTRACT

Aim:
The current research had an aim to evaluate the shear bond strength of two different pit and fissure sealants in deciduous teeth.

Materials and Methods:
Forty deciduous teeth were part of this research. Inclusion criteria were teeth having an unbroken occlusal surface, whereas samples having developmental defects/afflicted with caries were subjected to exclusion from this research. Each specimen tooth was assigned at random to one of the two groups constituting 20 specimens each by means of a computer-generated randomization with two alphabets (A, B). Group 1: Conventional sealant, Group 2: Self-adhering flowable sealant. Following sealant coating, a shear load was placed via a universal testing apparatus in a manner parallel to the bonded edge at a speed of 0.5 millimeter/minute till the occurrence of a breakdown. Bond strength was subsequently measured in Mega Pascals (MPa).

Results:
13.86 ± 0.23 was the mean shear bond strength of self-adhering flowable sealant versus 11.48 ± 0.52 Mpa of conventional sealants. Statistically significant differences amid both groups were noted.

Conclusion:
The current research arrived at a conclusion that self-adhering flowable sealants exhibited superior shear bond strength in comparison to conventional sealants.

Authors: Vengail Sukumaran , Chandrakar Dharamveer , Naik Ajit K. , Nayak Amiya K. , Mahajan Akriti , Dutta Priyanjali 
Published: July 2023

ABSTRACT

Introduction:
In emergency surgeries, open abdomen or laparostomy, especially with perforated viscus, has been used primarily to prevent delayed ventral hernia, burst abdomen, and abdominal compartment syndrome. In the present study, the clinical and resuscitative factors that are linked with open abdomen morbidity are evaluated.

Material and Methods:
A retrospective analysis was done for all the subjects who were admitted at the tertiary care center between May 2020 and May 2022 for the open abdomen surgeries. These patients were examined to see whether they needed more postoperative care than usual, including the need for resuscitative treatments and other critical clinical indicators. Patients were evaluated if they had any complications. The data that were collected were analysed for any variance using analysis of variance considering P <.05 as significant.

Results:
A total of 100 subjects were analysed in this study. Forty nine patients had intra-abdominal sepsis of the 100 cases examined from historical case records and 1 had entero-cutaneous fistulas. These patients did not necessitate additional actions for intensive care unit care, resuscitation, an chest infection, extended hospital stay, or any disabilities compared to those who did not undergo laparotomy during the same period. In this group of patients with open abdomens, the immediate postoperative period was not linked to an increase in resuscitation efforts or a load on clinical staff. Once patients are stabilized, early definitive abdominal closure is advised to prevent problems associated to laparostomies.

Conclusion:
The quantity of initial fluid revival and the coagulation factors at the time of admission are not related to intra-abdominal sepsis and enteric fistula following laparostomy after significant abdominal injuries.
