Methods: Systematic literature review was performed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, on clinical case report / series and prospective / retrospective clinical studies that evaluated the healing of horizontal root fracture treated with various techniques in comparison to self-healing. This review was registered with PROSPERO database A literature search in Pubmed, Proquest, Open grey, Web of science, Cochrane database of systematic review and Cochrane central register of controlled trials databases. Results: The search retrieved 9360 articles from all the electronic databases. After elimination of duplicates and reading full texts, 56 case reports with more than 4 year follow up and Twenty retrospective and prospective studies were included based on inclusion and exclusion criteria. A total of 2409 teeth were assessed. Quality assessment was done using Newcastle-Ottawa Scale for observational studies and JBI tools for case report and case series. The clinical prospective and retrospective studies showed that the healing pattern was predominantly Type II for factors like tooth type (41%), root development (40%), fracture location (50%). Based on the treatment modality, splinting type (40%) and splinting duration also showed Type II healing (44%). Over-all, type II healing pattern (33%) was observed followed by type I (28%), IV (19%) and III (16%) after a HRF. However, the healing pattern observed in case reports showed 68% Type 1 healing pattern. Conclusion: Based on the analysis of clinical cases, hard tissue healing is observed in 68% of HRF. However, with prospective and retrospective studies show 33% connective tissue healing. The assessment of case reports needs to performed cautiously because of possibility of including publication bias of well healed cases and minimal publishing of negative results / failures. Abstract 2: Bibliometric analysis of articles published on use operating microscopes for endodontic surgery from 1992 to 2020 SARAVANAN POORNI, MANALI RAMAKRISHNAN SRINIVASAN Sri Venkateswara Dental College and Hospital, Chennai, Tamil Nadu, India Aim: Although there have been important developments in Endodontic Microsurgery in recent years, there is no current and comprehensive bibliometric analysis in the literature. Hence the current bibliometric analysis was done to analyse the number of research articles per year, active authors, organizations and the countries of the first authors involved in the research domain of Endodontic Microsurgery. Materials and Methods: Dimensions Database was used to search data published in Endodontic Microsurgery. Only article published between 1992 to 2020 were included for the study. The data from all the articles included in the study was extracted using Dimensions. VOS viewer was used to develop analysis tables and visualisation maps. Results: A total of 2560 publications were identified related to Endodontic microsurgery. Bibliometric analysis was performed for 1707 articles. There was a steady increase in the number of articles published every year from 1992 till 2020 and the year 2020 being the most contributing year. The most active countries in this field was United States. The most active authors were Euiseong Kim, Massimo Del Fabbro, Silvio Taschieri. Maximum number of articles in this domain was published in Journal of Endodontics and International Endodontic Journal. The authorship pattern showed an interdisciplinary and collaborative researches. Conclusion: The current analysis shows an increasing trend of published articles. However, it highlights the need for publishing quality data to promote availability of quality evidence for clinical practice. Abstract 3: Comparative evaluation of the effect of mixing and placement techniques on physical, mechanical, and chemical properties of mm-MTA and manually mixed MTA KALAISELVAM RAJESWARI, RUDRA KONINDALA, G. ARATHI, KANDASWAMY DEIVANAYAGAM, RAMESH SESHAN RAKKESH Sri Ramachandra Dental College, Chennai, Tamil Nadu, India Aim: To evaluate the effect of mixing and placement techniques on sealing ability, push out strength and calcium release, alkalinity and solubility in open apex situations. Materials and Methods: One twenty human maxillary anterior teeth with mature roots extracted for periodontal reasons were selected to analyse the sealing ability and push-out strength at the root dentin-material interface. The teeth were decoronated with a diamond disc standardizing the root length to 15mm. To simulate immature open apices, the apical 3mm of the roots were removed and canals were widened with Gates Glidden drills size 4 to obtain 0.5-1.5mm dentinal walls. After shaping and cleaning the canals, the teeth were assigned to four experimental groups. Mechanically mixed MM- MTA and manually mixed MTA were placed using the manually or ultrasonically agitation technique. Sealing ability was analysed by measuring the depth of Rhodamine B dye penetration and Push-out strength was measured using the universal testing machine at the root dentin-material interface. Sixty plastic moulds of 5mm length and 5mm diameter were prepared. MM-MTA and MTA were manually or ultrasonically placed as per the assigned groups. After filling, the moulds were weighed to check the standardization of the amount of material in each mould. The moulds were split open and each specimen was immediately immersed in tubes containing 10 ml of deionised water at 37°C throughout the study period. The pH was measured using a pH meter, atomic absorption spectrophotometry was used to quantify the calcium release and the solubility was volumetrically analysed by weighing the percentage of weight loss at 3, 24, and 168 hours. X-ray diffraction analysis was performed to confirm the presence of added accelerators such as calcium carbonate in MM-MTA. The results were statistically analysed using the One-way ANOVA and Tukey's HSD test. Results: MM-MTA placed using ultrasonic agitation technique (Group A) performed significantly better when compared to other groups in terms of sealing ability, push out strength, amount of calcium release, pH and solubility of the material. Conclusion: The inherent composition of the MM-MTA, encapsulation and ultrasonic placement leads to superior properties and chemical Abstract Comparative evaluation of depth of penetration of using using study KANDASWAMY College and and Ramachandra of Dental Sri Ramachandra of Higher Education and Research, Chennai, Tamil Nadu, India Aim: This study to the depth of penetration of using and dentinal at the and apical of the root canal by using Materials and Methods: Sixty extracted teeth were selected and were decoronated at the and were performed using with The used was with Rhodamine B The were assigned four groups I II III and IV were at and from the apex in and were analysis was done using ANOVA with Tukey's to penetration the dentinal in the and apical of the root Results: The with showed the statistically depth of penetration of at the and apical of the root canal compared to the other and ultrasonic Conclusion: showed better depth penetration of in the dentinal of root canals, to the the dentinal root canal Abstract of Dental College and of Higher Education and Research, Chennai, Tamil Nadu, India in have the of and tissue have up to is an to – it a as a to an by with and that by – is of of the that to from the and placed a This review the of the recent and to a quality of Abstract Comparative evaluation of the of and using study Sri Ramachandra Dental College and Hospital, Chennai, Tamil Nadu, India been well in the endodontic literature that is an when used at from to in endodontic with the increasing with the increase in The of this was when with the been to increase the effect on Hence of this study was to analyse the of and at various by the of Materials and Methods: The were from and for hours. in well and for The and and with the groups were added to the groups of well and for hours. the was added to each and in for for the of of each well using the based on at Results: there was in an increase in when of all the of and there was no in and Conclusion: significantly increase the of of the There is a for the use of in non-surgical root canal and in in teeth with immature by of increase in Abstract of various root canal techniques on of – study ANISHA Dental College, Chennai, Tamil Nadu, India Aim: To evaluate the effect of various root canal techniques on of using study.
