A bstract Background One of the cardinal points to be considered during endodontic procedures in children is the measure of postoperative pain. Aim and objective To evaluate the quality of obturation and its effect on postoperative pain with three file systems in primary mandibular molars during 1 week follow-up. Materials and methods The study was conducted as a double-blinded randomized controlled trial. The participants between 6 years and 9 years old requiring a pulpectomy were recruited for the trial. Forty-five primary mandibular molars were randomly allocated into 15 teeth each in Hand K-files; Kedo-SH and Kedo-SG Blue groups. Wong Baker's FACES Pain Rating Scale was used for assessing the postoperative pain in the children for 1 week. Pearson's Chi-square test, Kruskal–Wallis test, and Mann–Whitney U test were used for analyzing the data statistically. Results Optimal fillings were observed more in the Kedo-SG Blue group (80.0%) compared to the other two groups ( p < 0.017). On intergroup analysis, the Kedo-SG Blue group reported less postoperative pain compared to Kedo-SH group on day 1 while on day 7 no postoperative pain was experienced in either of the groups. Less postoperative pain was reported by the children in whom the canals were optimally filled compared to overfilling and underfilling. Conclusion Kedo-SG Blue resulted in less postoperative pain when compared to Kedo-SH and hand K-files, whereas optimally filled children experienced less postoperative pain compared to overfilling and underfilling. Clinical significance A felicitous pediatric dental practice includes appropriate assessment and management of postoperative pain in children. Hence, the present study is important in highlighting the affiliation of postoperative pain with quality of obturation following an endodontic intervention in children.

Treating children under general anaesthesia (GA) has become an essential phase of dentistry. However, it is of paramount importance for the general dentists (GDs) and specialist practitioners (SPs) to have adequate knowledge regarding the necessary treatment criteria and guidelines laid down for treating children under GA. The present study aims to assess the knowledge and practice regarding the treatment criteria used for treating children under GA among GDs and SPs. A convenient sample of 200 participants were enrolled, and the study was conducted among GDs and SPs in three different dental colleges and hospitals in India. A validated questionnaire was used to evaluate the knowledge, attitude and practice about the treatment criteria and guidelines followed for treating children under GA among the participants. A significant correlation was outlined between the different age group of practitioners and an increase in the number of GA cases performed by them in the last ten years (p= 0.011), where more number of participants in the age group of 20-25 years reported an increase in the number of GA cases performed by them in the last ten years. Another significant correlation was observed between the years of experience of practitioners and the number of GA cases performed by them in the last ten years (p= 0.048). It was found that an increased number of participants in their initial years of practice (i.e., 0-5 years) preferred treating children under GA which eventually increased the number of GA cases performed by them in the last ten years. The clinical practitioners should strictly follow the necessary treatment criteria and guidelines laid down for treating children under GA in their routine practice. An increasing trend of performing GA in dentistry have encouraged more of clinical practitioners for treating children under GA.
