Background. This research aimed to investigate and compare the amount of apically extruded debris after root canal preparation using ProTaper Next, ProTaper Gold, and TruNatomy systems. Methods. Forty-five extracted mandibular premolar teeth with single canals with similar lengths were used. The root canals were prepared using ProTaper Next (Dentsply Maillefer, Ballaigues, Switzerland), ProTaper Gold (Dentsply Maillefer, Ballaigues, Switzerland), or TruNatomy (Dentsply Maillefer, Ballaigues, Switzerland) files. Apically extruded debris during preparation was gathered into preweighed Eppendorf tubes. Then the Eppendorf tubes were incubated at 70°C for five days. The Eppendorf tubes were weighed again to determine their final weight plus the extruded debris. Results. The TRN system resulted in significantly less debris extrusion than the PTN system (P0.05). Conclusion. All the instrumentation systems caused apical extrusion of debris. However, the TRN system resulted in significantly less debris extrusion than the other systems.

Aim: To determine the current status and trend of endodontic research in Türkiye.Materials and Methods: A comprehensive literature survey was conducted using the Clarivate search engine. Keyword selection was as follows: “Endodontics” and “Türkiye”. All publications until May 2022 were included. The search was restricted to endodontics. Title, first author, country/institute, journal name, publication year, citation, abstracts, and keywords were recorded. VOSviewer version 1.6.10 software was used to map the bibliometric network of the exported data that has an automatic term identification algorithm.Results: A total of 672 articles between 1985-2022 years were included. The scientific contribution rate of Türkiye was found 4.12% in the field of Endodontology. The highest number of publications is in the category of ‘Dentistry Oral Surgery Medicine’ with 588 articles and 384 (73%) published by Journal of Endodontics.Conclusion: This bibliometric analysis highlights Türkiye’s contribution to the field of Endodontology. Research articles have been contributed by various authors and institutions.

Aim: The aim of this study was to determine level of knowledge and awareness of the dentists in Turkey about the endo-perio lesions.Materials and Methods: 225 dentists who answered the questionnaire from 387 dentists were included in the study. In the survey consisting of two parts, 12 questions were asked on demographic information, risk factors and the definition of the disease. The data obtained were analysed with Minitab 17 statistical software using T test, Chi-square test and Mann-Whitney U test.Results: Endodontics (p=0.001) and periodontists (p<0.001) were found to be significantly aware of EPL. It was observed that general practitioners did not have significant awareness about EPL (p<0.001)Conclusion: The level of awareness about EPL in specialist dentistry other than endodontists and periodontologists was found to be lower in non-specialist dentists.

The objective of the current survey was to assess the awareness of the dental professionals according to the principals described by the Turkish Dental Association (TDA). A questionnaire including the socio-demographic data, specialties/academic degree, institutions/affiliations, the knowledge about COVID-19, the number of patients examined and dental treatments performed during the COVID-19 pandemic, the knowledge of protection based on the guidelines described by TDA, contamination with COVID-19 and the psychological complaints has been used. A total of 947 (63.1%) dentists enrolled the study. The results showed satisfactory knowledge about the COVID-19 etiology, mode of transmission and the pre-procedural cautions as the majority of them had a fair level of knowledge with significantly higher knowledge among specialized respondents. The participants have also recorded a good judgment towards performing the emergency dental treatment during the current COVID-19 pandemic which corresponds with the guidelines determined by TDA. Considering the updates on the transmission of COVID-19 and protective strategies, there is an urgent need for improvement of dentists’ knowledge about risk assessment via training programs. The incidence of positive testing among dental professionals also necessitates immediately testing of asymptomatic Turkish dental professionals.

Objective: The purpose of this study is to describe oral health behaviour of the individuals and determine the relationship level of knowledge of the participants about dental health and procedures and their personal variables. Methods: The total number of participants who answered the questionnaire was 575. Oral health behaviours were assessed according to tooth brushing frequency, dental floss or interdental brush use, when was the last time he/she went to dentist and their reason for going to the dentist. Also, the eight dental health knowledge items were selected to determine the individual’s dental health knowledge status. Results: There was no statistical difference between the ages of the participants and the knowledge levels of dental health and procedures (p=0.089, p>0.05). There was statistical difference between level of education and the knowledge levels of dental health and procedures (p=0.001, p<0.05). There was statistical difference between level of family income and the knowledge levels of dental health and procedures. (p=0.001, p<0.05). There was statistical difference between dental floss or interdental brush using and the knowledge levels of dental health and procedures (p=0.001, p<0.05). Conclusion: The findings of the present study showed that Oral hygiene habits and oral and dental health knowledge level is insufficient in our society. Preventive and educational programs should be developed in order to both improve and inform individuals about oral care.
