Perception of the clinical endodontic practice of Dentistry graduates in their first years in the job market in southern Brazil

Introduction: Knowledge about the clinical endodontic practices of dental school graduates in the first years of their professional life may contribute to the discussions about Dentistry teaching. Methods: An online questionnaire with seven open and closed questions hosted on the Google forms platform was applied to dentists trained in the first half of 2019 in a School of Dentistry in southern Brazil. The questionnaire is structured to analyze how clinical Endodontics has been practiced in the labor market. The data collected in the questionnaires were transferred to an Excel® spreadsheet and analyzed as absolute and relative frequencies for closed questions and descriptions for open questions. Results: Molars and two-rooted teeth are the dental groups most frequently treated endodontically (64.3% and 35.7%). Both retreatment and conservative treatment of the pulp corresponded to up to 25% of all procedures in the graduates' clinical practice. The endodontic protocol learned in their dental school was used by 64.3% of the graduates who provided endodontic treatments, and 42.9% reported the occurrence of at least one accident. The difficulty in access reported by the participants suggests that more training should be provided for this operative stage. Conclusions: After two years in the job market and having faced the initial difficulties existing in any profession, more than half of the graduates still performed endodontics in their dental clinical practice and used the same protocols learned in dental school.

THE POST TRANSFIXED IN THE CORONAL CAVITY INCREASES THE FRACTURE RESISTANCE OF WEAKENED AND DIRECTLY RESTORED TEETH? A SYSTEMATIC REVIEW

Introduction: The objective of this systematic review was to answer the question: Does the intraradicular post transfixed in the dental crown increases the fracture resistance of weakened and directly restored teeth? Methods: Electronic databases (MEDLINE/PubMed, LILACS, SCOPUS, EMBASE, Scientific Electronic Library Online - SCIELO, and Central Register of Controlled Trials - CENTRAL) were searched until March 2021, without language or year restriction. Grey literature was also searched through Google scholar and OpenGrey repository. Only in vitro stud-ies were included that evaluated the influence of the use of intraradicular post trans-fixed in the crown in the buccopalatal/lingual direction in the fracture resistance of the dental crown. Relevant results were summarized and evaluated. The risk of bias was also assessed in the studies. Results: Initial screening of databases resulted in 249 studies, of which 109 were excluded for being duplicates. Of 140 eligible pa-pers, fourteen studies met the inclusion criteria and were selected for full-text read-ing. Of these, two studies were excluded for not having access to the full article. All selected articles were classified as low risk of bias. Conclusion: Based on the studies, it is possible to conclude that the use of a transfixed post in the crown increases the fracture resistance of weakened and directly restored teeth.
