Background. Citation analysis has emerged to play a significant role in recognition of the most useful areas of research. Endodontic microbiology has been a topic of interest for endodontists as well as periodontists and oral surgeons. This bibliometric analysis is aimed at identifying and reporting the characteristics of the top 50 cited articles on endodontic microbiology. Methods. The articles were identified through a search on Web of Science (WoS), property of Clarivate Analytics database published on endodontic microbiology. The citation information of the selected articles was recorded. The Journal of Endodontics, International Endodontic Journal, Oral Surgery Oral Medicine Oral Pathology Oral Radiology and Endodontology, Dental Traumatology, and Australian Endodontic Journal were searched in the search title. Descriptive and bivariate analyses were performed using a statistical software package SPSS. Statistical analysis was performed using Shapiro-Wilk, Kruskal-Wallis, Post hoc, Mann-Kendall trend, and Spearman-rank tests. Results. The 50 most cited articles were published from 1965 to 2012 with citation count varying from 1065 to 103 times. The total citation counts of articles recorded were 11,525 (WoS), 12,602 (Elseviers’ Scopus), and 28,871 (Google Scholar). The most prolific years in terms of publications were 2001, 2002, and 2003, with five publications each, followed by 2005 with four. The year with most citations was 1998, with 1,330 citations, followed by 1965 and 2001, with 1,065 and 1,015 citations, respectively. A total of 136 authors contributed to the top 50 most cited articles with 27 corresponding institutions from 12 different countries. The most common methodological design was in vitro study, followed by clinic-laboratory study, literature review, systematic review and meta-analysis, and animal study. Conclusions. The present study provided a detailed list of the top 50 most cited and classic articles on microbiology in endodontics. This will help researchers, students, and clinicians in the field of endodontics as an impressive source of information.

Introduction: Direct pulp capping treatment (DPC) maintains pulp vitality by promoting healing or repair in dentistry, which can be attributed to the advent of bioceramic materials. Aim: This examination looked to evaluate the clinical and histological effectuality of Biodentine with Dycal for DPC. Materials and Methodology: In this study, 30 intact human orthodontic teeth undergoing therapeutic extraction were chosen to perform DPC. They were arbitrarily divided into two groups ( n = 15) and DPC with Biodentine and Dycal was performed. Composite resin was used as permanent restoration. After a period of 1 and 6 weeks, clinical as well as electric pulp tests were carried out. Asymptomatic patients were re-called after 6 weeks; follow-up radiograph was taken. Electric pulp testing and thermal testing was done to check the pulpal status of the teeth. This was followed by atraumatic extraction, and the teeth were sent for histological examination. SPSS Version 21.0. Armonk, NY: IBM Corp.was used for data analysis. Results: There was no pain and sensitivity in using Biodentine. Whereas, sensitivity and pain was noted when Dycal was used. The dentinal bridge was better with Biodentine when compared with Dycal. Conclusion: In accordance with the obtained results, it was concluded that on clinical and histological evaluation, Biodentine performed better as DPC agent. Subsequently, Biodentine is more dependable for the long-haul protection of dental pulp than Dycal.

Optimal tissue regeneration in the periapical region is essential following a periapical surgery. Literature shows that augmenting the osseous defect with artificial bone substitutes, growth factors, or barrier membranes acts as critical factors influencing the healing following surgical intervention. For the regeneration of tissues following periapical surgery, an essential requisite is progenitor/stem cells. Few studies have shown that simple use of a membrane barrier and/or bone graft following surgery might not produce adequate tissue regeneration. Literature clearly shows that few substitutes are capable of generating progenitor/stem cells and induce the undifferentiated mesenchymal cells to differentiate. Hence, this review is intended to throw light on whether tissue regeneration with the aid of bone grafts coupled with a membrane barrier will suffice or is there a need for recruiting progenitor/stem cells.

Aim and Objectives: The aim of this study is to evaluate the internal margin adaptation and integrity of Class 1 preparations using two composites types (bulk fill/conventional) with two placement methods (4/2 mm increments). Materials and Methods: Class 1 preparations of 4 mm × 4 mm dimensions were made on 30 extracted human mandibular molars. They were randomly divided into three groups; among them, in Group 1 ( n = 10), cavities were filled with SureFil SDR Bulk Fill, Group 2 ( n = 10) cavities were filled with Filtek Bulk Fill of 4 mm increments in both groups, and in Group 3 ( n = 10), cavities were filled with conventional composite Filtek Z350 with 2 mm increments. Samples were sectioned occlusogingivally. Then, dye was on internal margins, and images of each specimen were recorded using a digital camera to evaluate the marginal integrity and adaptation of restorative material to the tooth surface with image analysis software. Then, collected data were put under the statistical analysis with analysis of variance test and post hoc Tukey's test. Results: There was no significant difference in overall dye penetration in bulk fill and conventional (incremental fill) composite resins; however, when dye penetration was evaluated at different locations, within enamel and mid-dentin, significantly more gap-free margins were found than at the pulpal interface. Filtek Bulk Fill and conventional composite (Filtek Z350) showed comparatively more dye penetration toward the pulpal interface compared to SDR Bulk Fill. Conclusion: There were no significant differences in percentage of gap-free margins between fill types for any of the composite materials. The proportions of gap-free margin were less at the pulpal interface and mid-dentin portions and enamel when filled with 4 and 2 mm increments.
