Investigation of the coronal restoration preferred endodontically treated teeth of dentists in Turkey

It is a proven fact that the upper restoration of endodontic treated teeth can affect the outcome of endodontic treatment. The purpose of this study, treatment of root canal dentist in Turkey to investigate the top choice in dental restorations. In the current study, the questionnaire created to collect data includes 30 questions. In the first part of the questionnaire, 7 demographic questions about the general characteristics of the participants (age, gender, specialty experience, graduation program, institution, scientific congress, seminar or presentation participation), in the second part, multiple choice questions were asked by dentists to determine the type of upper restoration of endodontically treated teeth. In order to determine the timing, preferred material and treatment protocol, 15 questions and 8 questions questioning restoration preferences through various cavity drawings were included. The majority of the 311 participants who answered the questionnaire stated that they did the upper restoration themselves and preferred to complete it immediately after endodontic treatment. Participating physicians stated that they mostly used composite resin as the post material and fiber post as the post material most frequently and adhered with adhesive resin cement. Most of the participants reported that the ferrule effect increased fracture resistance in endodontically treated teeth (p <0.5). Participants' rate of using rubber dam was found to be quite low; stated that they preferred it most frequently in the lower molar tooth group when they used it (p <0.5). While a great majority of the participants stated that they did not get help from magnifying devices during endodontic treatment, it was determined that the use of loop was higher than dental operation microscope and endoscope (p <0.5). As a result of the present study, it was determined that the participating physicians were aware of the immediate upper restoration after endodontic treatment. However, it was determined that the preference of adhesive applications is increasing. Within the limitations of this study, it was found that there were deficiencies in the evaluation of the upper restoration preferences of physicians for endodontically treated teeth. For this reason, it is thought that courses and trainings on upper restorations in endodontically treated teeth are necessary in order to eliminate this deficiency.
