This systematic review aims to compare the success rate of Endosequence bioceramic root repair material (BCRRM), mineral trioxide aggregate (MTA), and calcium hydroxide for apexification of necrotic immature permanent teeth. Indexed Journals such as Google Scholar, PubMed, Scopus, Cochrane, Research Gate, Wiley Online Library, and other related journals were hand searched from inception till November 2020 and articles were selected for review based on PRISMA guidelines. Of the 410 studies that were identified, 150 articles were selected after title/abstract reading. After full-text reading and based on inclusion and exclusion criteria, 9 studies were finalized for systematic review. Clinical, radiographic success, and the time taken for apical barrier formation were reviewed. All the three materials had almost similar success rate in terms of clinical symptoms, but the time taken for apical barrier formation and also single visit treatment makes MTA and Endosequence BCRRM superior to calcium hydroxide. Studies comparing EndoSequence Root Repair Material and MTA are very limited and need further evaluation in the future.

Purpose: The goal of this study is to look into several approaches to approaching damaged instruments in the root canal, as well as to show possible outcomes in terms of dentin thickness, fracture resistance, technique success, and clinical time. Methodology: PubMed, Cochrane, Lilacs, Web of Science, Scopus, grey literature, and manual searches were used to conduct the bibliographic research. The titles and abstracts of 506 papers were examined using the inclusion and exclusion criteria. Sixty items were chosen and read in their entirety. This systematic review includes fourteen papers. Results: The ultrasonic approach was the most extensively researched and yielded positive results in general. The more apically positioned the tool is, the more difficult it is to remove it, the more dentin is removed, and the poorer the tooth's fracture resistance. When removal is not possible, the bypass technique (bypassing) can be employed, and the GentleWave System approach can be used on weakened teeth or with little dental fragments. Conclusion: The data from laboratory investigations showing the curvature and root third in which instrument fractures originate is related to fracture resistance and success is presented in this comprehensive review.

Introduction: In oral and maxillofacial surgery, their clinical application has largely been restricted to soft tissue. Hence, the aim of this study was to assess the feasibility of erbium-yttrium aluminum garnet (Er: YAG) laser in bone cutting for removal of impacted lower third molar teeth and to compare its outcomes with that of surgical bur. Materials and Methods: The study comprised forty subjects requiring removal of impacted mandibular third molar, randomly categorized into two equal groups of 20 each, who had their impacted third molar removed either using Er: YAG laser or surgical bur as per their group, using standard methodology of extraction of impacted teeth. Clinical parameters such as pain, bleeding, time taken for bone cutting, postoperative swelling, trismus, wound healing, and complications were compared for both groups. Results: Clinical parameters such as pain, bleeding, and swelling were lower in laser group than bur group, although the difference was statistically not significant. However, postoperative swelling showed a significant difference in the two groups. Laser group required almost double the time taken for bone cutting with bur. Trismus persisted for a longer period in laser group. Wound healing and complications were assessed clinically and there was no significant difference in both the groups. Conclusion: Based on the results of our study, the possibility of bone cutting using lasers is pursued, the osteotomy is easily performed, and the technique is better suited to minimally invasive surgical procedures. The use of Er: YAG laser may be considered an alternative tool to surgical bur, especially in anxious patients.
