ABSTRACT
Introduction: Many adjuvant methods have been researched to enhance the immediate implant success in the recent times. The study's goal was to compare the aesthetic and biological results of immediate dental implants in the aesthetic zone to standard tapered root form implants that had not undergone pre-treatment with platelet-rich plasma or photofunctionalization. Materials and Methods: The study used a randomized controlled trial as its design. Ninety subjects were chosen at random and placed into three groups: a control group, a case group, and a group that needed replacement of their maxillary anterior teeth right away following extraction. The interventional groups received the "Platelet-Rich Plasma (PRP)" or "Photofunctionalization (PF)" group before the implant placement. After the delayed loading approach, the prosthesis was given after 6 months. At the second and fourth weeks, as well as 2, 4, 6, and 12 months (P 0.05), follow-up was conducted. The success and survival rate, aesthetic, and biological outcomes were assessed. One-way ANOVA was used to compare outcomes, and repeated-measures ANOVA was used to assess intragroup variations over baseline and follow-up. Results: The distal, mesial, and mean marginal bone loss as well as the aesthetic scores for pink and white did not differ significantly between groups. The implant stability however was significantly higher in the PF and PRP groups as compared to the controls. A single implant failed in all the three groups. The success percentage was similar for all the groups. Conclusion: The stability of immediate dental implants pre-treated with PRP or PF differed statistically significantly than the subjects in the control group, while other parameters remained the similar between the groups.
ABSTRACT
Introduction: Surface roughness of the crowns is dependent on the pattern material used for the making as well as the procedure of investing. The study was aimed to examine the impact of various pattern materials and investment procedures on the surface roughness of nickel-chromium alloy raw castings. Materials and Methods: An in-vitro study was piloted at a tertiary care hospital. Eighty samples of inlay wax and pattern resin were divided equally. They were invested in phosphate-bonded investment material and kept under normal atmospheric pressure as well as invested under a pressure of 3 bars. The surface roughness was calculated with a Profilometer. The values obtained were compared using statistical tools keeping P < 0.05 as significant. Results: Lowest surface roughness was seen for the wax pattern invested under positive pressure. While the highest was seen for the resin patterns invested at room pressure. A significant variance between the wax 1 and wax 2 (P < 0.01); as well as between the wax 2 vs. Resin 2 specimens (P < 0.01) was noted. Conclusions: Wax patterns can be suggested as the material and method of choice because they showed the least amount of surface roughness when placed under pressure. Resin patterns when invested under pressure can also be suggested as an alternate as they also exhibited similar surface roughness as that of the wax.
ABSTRACT
Introduction: One of the hormones that are crucial in safe pregnancy is the Progesterone. Its defect may cause bleeding and abortion. Hence, in this study, we evaluated two different drug modalities of progesterone for their efficacy. Material and Methods: We piloted a prospective observational study among 100 pregnant women in their first trimester. They were divided to two equal groups to receive oral dydrogesterone and vaginal progesterone. The clinical and the demographic data with detailed history were taken and noted. The patients were followed up till the pervaginal bleeding stopped and till second trimester end. The comparisons were made between the groups using Chi square test deliberating P < 0.05 as significant. Results: The age, BMI, and the progesterone levels were comparable between the groups. No significant difference between the groups was seen for the adverse reactions and for the continuation of pregnancy till 24 weeks. However, there was a significant variation in the cessation of the pervaginal bleeding, with lower time for the oral dydrogesterone. Conclusion: Compared to the vaginal progesterone, oral dydrogesterone performed better in preventing the pervaginal bleeding and prolonging the viability of the pregnancy till the second trimester end.
ABSTRACT
Introduction: The most common for the replacement for the teeth are the partial dentures. Hence, in our study, we analyzed the failure rates of the fixed partial dentures (FPDs). Materials and Methods: We conducted a retrospective study from the institutional record and analyzed 150 subjects. The various factors for the FPD's failure were noted and analyzed for any statistical significance. Results: We observed a significant difference between the various factors of the failure caries, periodontitis, uneasiness, and pain. Conclusion: The chief cause for the failure of the FPDs was identified to be caries, periodontitis, uneasiness, and pain.
