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
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.
