This meta-analysis is intended to evaluate the reliability of evidences published in current regenerative endodontic publications in a critical way. This meta-analysis is used to summarize and analyze the various clinical and radiographic findings associated with nonvital immature permanent teeth which have been treated with regenerative endodontic techniques. We also intend to significantly evaluate the worth of facts provided in the previous published literature. A structured electronic search by authors was undertaken in August 2020 using MEDLINE and PubMed search engine. The chosen parameters studied in this systematic review were presented in flowcharts and were summarized. We observed a good accomplishment rates in terms of survival of the treated tooth and also in resolution of any associated pathology in the apical areas; on contrary, our results in relation to apex closure along with constant root development, our findings from various studies were quiet variable. Regenerative endodontic procedures are constantly being restructured and enhanced to benefit present-day dentistry in all likely ways. Still, many factors that are important for the success of regenerative endodontic treatment outcomes still remain unexplained. There are still numerous gaps in our expertise at the present stage of this study.

Aim: Managing postoperative pain following maxillofacial surgery is an important task. Our study aims to compare this with regional anesthesia or IM diclofenac. Materials and Methods: This study included 30 patients who underwent bi-jaw orthognathic surgery between April 2016 and January 2020. Two groups were formed. Group A was administered inferior alveolar nerve block at the surgical site bilaterally using 0.5% ropivacaine and Group B were administered 75 mg intramuscular diclofenac just before extubation. Tramadol HCl 2 mg/kg body wt is used as a rescue analgesic. The pain was evaluated periodically at 2 nd , 4 th , 6 th , and 12 h postoperatively. Results: The mean Visual Analog Scale score was 2 in Group A and 5 in Group B. The mean duration of analgesia was 6 h 42 min, whereas in Group B, it was 8 h and 5 min. In 2 patients (13.3%) belonging to Group A and 3 patients (20%) belonging to Group B. There were no local complications in any group. Conclusion: It was observed that regional anesthesia in the form of intraoral nerve blocks was efficient than diclofenac (75 mg) administered intramuscularly for the management of immediate postoperative pain.

Aim: The purpose of the present study was to assess the efficacy as well as pain perception status in patients, who have been administrated Inferior Alveolar Nerve Block (IANB) for third molar extraction by both closed mouth as well as open mouth techniques. Methodology: 90 patients were enrolled in the present study. The patients were given inferior alveolar nerve block to extract mandibular third molar by three different techniques. They were divided in 3 groups of 30 patients each in which conventional open mouth, Fischer 123 technique, closed mouth Vazirani Akinosi technique were assigned with Group I, II, III respectively. Pain Perception (VAS), Speed of anaesthesia, Patient anxiety and Clinician expertise were measured. Results: The results show that intra-oral conventional technique is less technique sensitive as compared to Vazirani-Akinosi and Fischer's 123 techniques. Former is still the best in terms of less expertise required as well as pain perception by the patient. Conclusion: Conventional open mouth technique is still the most popular choice amongst clinicians and the pain sensitivity is also negligible amongst the patients with this classic intra-oral technique. Indirect as well as closed mouth technique requires more skilled expertise but can be used in cases with limited mouth opening.
