RESUMO
Aim: This systematic review was conducted with the purpose of analyzing the effects of root-end sealers in endodontic re-treatment cases and comparing calcium-based sealers with sealers, which were resin-based. Methodology: We conducted this review based on the principles of Cochrane systematic type of studies and also based on guidelines of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). An exhaustive search was conducted across PubMed, Medline, and Embase databases for the studies, which were based on root end sealers in cases of endodontic re-treatments. The data were then analyzed statistically with the help of SPSS 25.0. Results: It was seen that when comparing pain levels in post-obturation cases with these sealers after 24 hours and 48 hours, not much of statistically noteworthy differences were evident. Mean difference (MD) values at 24 hours were -0.20 with confidence intervals between -0.44 and 0.07 and P value of 0.15, whereas in case of 48 hours, MD was -0.36, CI- 0.65, and P value was 0.03. However, the results were slightly better with calcium-based sealers. Conclusion: Calcium silicate-based root end obturation sealers had similar performance when compared to resin-based sealers when we compared variables like pain intensity, etc.
RESUMO
Aim: In this systematic review, we assessed whether the effects of the usage of various devices help with magnification in endodontics and whether they resulted in any significant changes in the clinical result of treatment. Materials and Methods: An exhaustive search was performed across MEDLINE and Cochrane Registers for various clinical studies, which were focused on comparing regenerative endodontic treatment based on the usage of magnification devices. Various terms were used to search these clinical trials such as microscope, regenerative endodontic surgery, apicoectomy, endoscope, and loupes. Results: After scrutinizing the studies, around three clinical trials based on magnification in endodontic surgeries were included in the present review. It was observed that no statistically noteworthy betterment of treatment outcome was seen in patients treated with either of the magnification devices such as loupes and microscope. Conclusion: It was evident that these magnification devices can alter the effectiveness of regenerative endodontic treatment in a very minimal way. However, we believe that more randomized clinical studies should be conducted in this area.
