Knowledge and clinical experiences of pediatric dentists and endodontists regarding regenerative endodontic procedures

Aim: Pediatric dentists and endodontists perform regenerative endodontic procedures (REPs) on immature permanent teeth with necrotic pulp. The aim of this survey was to gather information about the knowledge and clinical experiences of pediatric dentists and endodontists regarding REPs. Material and Methods: A 23-question survey was formed and a participation link was sent via e-mail. The questions were prepared based on AAE guide. The survey consisted of various types of questions to obtain information about the physicians' age, gender, education information, previous regenerative endodontic therapy (RET) experiences and preferred REPs clinical protocols. Results: A total of 207 volunteers, 101 pediatric dentists and 106 endodontists participated in the study. RET was chosen by 68.1% of participants as their first choice in incisors, 50.2% in premolars and 40% in molars. The most important criterion is the stage of root development (44.8%) to decide between RET or apexification; 53.5% of the participants learned about REPs during residency training; 70.5% of the participants had applied REPs before (pediatric dentists (77.2%), endodontics (64.1%)). Most of the physicians stated that a candidate suitable for RET in the future would encourage them to practice. Discussion: The majority of pediatric dentists and endodontists do not adequately follow published standard clinical protocols. However, conducting studies under standard conditions is very important in evaluating the results of clinical protocols. This is very thought-provoking that even specialist physicians who can treat patients in this regard are confused. Therefore, physicians should be informed about this issue and a common protocol should be adopted in treatments.
