ABSTRACT
Introduction: Tranquility therapies have recently been more popular as a means of reducing anxiety amongst children in the course of painful diagnostic and therapeutic procedures. As a result, a variety of techniques (oral tranquility, intravenous (IV) tranquility) have been developed to assist practitioners in order to deal with such instances. The goal of this trial was to see how effective propofol could be in calming anxious youngsters during the course of dental therapy. The interventional investigation was undertaken at the Hazaribag College of Dental Sciences and Hospital in Jharkhand. Materials and Methods: To assess the outcomes of intravenous propofol on their performance in the course of therapy, 40 children within the age group of 3-6 years pursuing good physical health but uncooperative in nature (negative or definitely negative, bestowing to Frankel's performance scale) were comprised in the study. The performance rating scale was utilized to assess their performance throughout the therapy (BRS). In addition, the point of tranquility was assessed beforehand. Mann-Whitney U test was utilized to equate male and female points of performance along with gradations of drowsiness. The P value for significance was fixed at 0.05. Results: All participants' performance and point of tranquility in the course of therapy were promising, and therapy was accomplished for everyone. Mann-Whitney U test revealed no statistically significant differences in point of performance, or gradation of drowsiness amid males and females. Pearson's correlation coefficient revealed a strong positive association of therapy time with awakening time. Conclusion: Intravenous propofol deep tranquility in the presence of an anesthesiologist was found to be beneficial in restraining nervous and recalcitrant youngsters in the course of dental therapy.
ABSTRACT
INTRODUCTION: Pediatric dentistry has evolved from extraction acclimatized practice to prevention and preservation. Successful endodontic treatment is mandated for retention of pulpally involved primary teeth. AIM AND OBJECTIVE: To comparatively evaluate the obturation techniques namely lentulospiral and skini syringe with NaviTip in primary teeth using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: The study was carried out among children ranging between the ages of 4 years and 8 years of either sex with pulpal involvement of primary molars which were indicated for pulpectomy. The study population was divided into two groups according to the type of obturating technique used. Group I included samples obturated with lentulospirals while group II samples were obturated using skini syringes with NaviTip. Postoperatively, CBCT imaging was used to evaluate the quality of fill of both the obturation techniques by determining the presence of voids in the root canals. RESULTS: The total number of voids present in group I were 48, in which, 8 were in the coronal third, 16 in the middle third, and 24 in the apical third. On the other hand, the total number of voids present in group II was 21, out of which 7 were in the coronal third, 10 in the middle third, and 4 in the apical third. A statistically significant difference was noted between the two groups in terms of the overall voids present. CONCLUSION: Within the limits imposed by the conditions used in the present study, both techniques can be used for obturation in the root canals of primary molars. Voids were observed with both the techniques, but minimum in group II, i.e., skini syringe with NaviTip. HOW TO CITE THIS ARTICLE: Nezam S, Mukherjee CG, Shukla JN, et al.

ABSTRACT
AIM: To compare the dimensional accuracy of polyether, polyvinyl siloxane, and polyether polyvinyl siloxane hybrid impression materials using closed tray, open tray splinted, and open tray nonsplinted coping impression techniques and to find out the best suitable impression material and technique combination for implant impressions. MATERIALS AND METHODS: The sample size of the study was 45. The combinations of materials and techniques were divided into nine groups, namely polyvinyl siloxane with closed tray, polyvinyl siloxane with open tray nonsplinted copings, polyvinyl siloxane with open tray splinted copings, polyether with closed tray, polyether with open tray nonsplinted copings, polyether with open tray splinted copings, polyvinyl siloxane-polyether hybrid with closed tray, polyvinyl siloxane-polyether hybrid with open tray nonsplinted copings, and polyvinyl siloxanepolyether hybrid with open tray splinted copings. Five samples of each group were evaluated. A total of 45 impressions were taken. A stainless steel master metal framework with three internal hex implants was fabricated and used to generate the samples. A common condensation silicone putty spacer was applied over the impression copings attached to the implants, which was then duplicated. All trays were fabricated on this duplicated silicone die using light cure acrylic resin. Trays to be used for open tray techniques had their top removed for gaining access to screws of the impression copings. Splinting of coping for OS group was done using pattern resin. Impressions were poured, and master cast was generated. Interimplant distance was measured using stereomicroscope and an image analyzing software. RESULTS: Open nonsplinted technique resulted in significantly better replication of implant positions compared to open splinted and closed techniques. Hybrid impression material depicted significantly better dimensional accuracy than polyether and polyvinyl siloxane. Hybrid open nonsplinted depicted least mean difference in interimplant distance, followed by hybrid open splinted and polyether open splinted groups. Polyvinyl siloxane closed tray showed maximum difference in interimplant distance in comparison with other groups. CONCLUSION: Polyvinyl siloxane-polyether hybrid impression material and open nonsplinted technique gave best replication of implant positions on the master cast. CLINICAL SIGNIFICANCE: Accuracy of impressions and casts is of great importance for the fabrication and long-term clinical success of precisely fitting implant-retained prostheses.

BACKGROUND: Depression, a multi-dimensional disorder adversely affects the interpersonal, social and occupational spheres of students' life. It is the 11th leading cause of global disease burden. AIMS AND OBJECTIVES: To assess the prevalence of depressive symptoms among various professional course students including medical, dental, and engineering students in Patna, Bihar. MATERIALS AND METHODS: The present investigation was a questionnaire-based cross-sectional descriptive study. A total of 3,100 students attending government and private medical, dental, and engineering colleges in Patna were approached during the course of this study. Students were briefed about the study and questionnaire. BDI-II (Beck's Depression Inventory-II) was administered to the students and they were instructed to fill it. Beck's scores were recorded and a descriptive analysis performed. RESULTS: 2798 students out of 3,100 responded positively to the survey by completely filling out the form. The overall response rate was 90.25%. The overall prevalence of depressive symptoms was found to be 47.78%. Of the three streams, students belonging to the engineering stream (40.28%) showed a maximum prevalence of depressive symptoms followed by dental (38.50%) and medical students (34.74%). CONCLUSION: Our study showed an alarming prevalence of depression among professional course seeking students. This multi-dimensional disorder continues to affect student's performance and professionalism, thus, extending its negative impact to the community at large. This may carry out later in their lives, thus leaving a long-term negative impact. Considering the high rate of depressive symptoms, establishing a unit or facility to identify or diagnose it at an early stage and providing psychological support to students is recommended.
