AI Article Synopsis
- Pulpotomy is a recommended treatment for deep caries and reversible pulpitis in children's teeth, but there’s a lack of extensive studies on its long-term effectiveness, particularly beyond two years.
- This study focused on comparing the long-term success rates of two materials, mineral trioxide aggregate (MTA) and iRoot BP Plus, used in pulpotomy performed under general anesthesia in primary molars.
- Results showed that iRoot BP Plus had significantly higher success rates than MTA at both 24 and 36 months, with the type of material used impacting the outcome, while other factors like age and gender did not significantly affect success.
Article Abstract
Background: Pulpotomy is a widely recommended treatment for deep caries and reversible pulpitis in primary teeth. However, there is a significant lack of large-scale clinical studies evaluating the long-term efficacy of pulpotomy in primary molars, especially in studies with follow-up periods extending beyond a two years.
Aim: This study aimed to evaluate the long-term efficacy of mineral trioxide aggregate (MTA) and iRoot BP Plus for pulpotomy in primary molars performed under general anesthesia and to investigate factors influencing the success rate.
Methods: In this retrospective study, a total of 942 primary molars from 422 children who met the inclusion criteria underwent pulpotomy. Propensity score matching method (PSM) was used to match the MTA and iRoot BP Plus groups in a 1:1 ratio based on covariates. Efficacy was assessed using the Zurn & Seale criteria. Kaplan-Meier survival analysis and Cox proportional hazards model were performed to analyze the outcomes.
Results: PSM resulted in 266 pairs of matched teeth from 532 teeth of 291 children (mean age: 4.64 ± 1.07 years, ranging from 2 to 8 years). Long-term clinical and radiographic evaluations revealed higher success rates for iRoot BP Plus (24-month: 99.54%/97.25%; 36-month: 97.22%/95.83%) compared to MTA (24-month: 94.76%/95.29%; 36-month: 92.50%/91.25%). Survival analysis indicated a statistically significant difference between two groups ( = 0.0042). Age, gender, tooth position, and decayed tooth surface showed no significant impact on pulpotomy success, whereas the choice of pulp capping materials significantly influenced the outcome (HR [95% CI]=0.3745[0.1857-0.7552], = 0.006).
Conclusion: Clinical and radiographic evaluations support the use of iRoot BP Plus for pulpotomy in primary molars.

Background: Binaural beat is created by presenting two different pure-tone sine waves with less than a 30Hz difference dichotically. In dental settings, children listening to familiar music during treatments gain control over the anxiety caused by tools like the airotor or syringe, creating a comforting, familiar environment.
Aim: To evaluate and compare anxiety level during restorative treatment using No Music, Music of choice and Binaural Auditory Beats as Audio distraction behaviour guidance technique in children aged 6-12 years.

Aim: The objective of the present study is to assess and compare the effectiveness of two different anesthetic agents, namely, 4% articaine and 2% lignocaine, in the extraction of primary molar teeth in children.
Materials And Methods: The study included 25 children requiring bilateral extractions of primary molar, with extraction performed on one side with 4% articaine and the contralateral side extraction with 2% lignocaine at two separate appointments. The anesthetic efficacy was evaluated objectively by assessing pain and the child's behavior at baseline, during injection and during extraction using the sound, eye, and motor (SEM) scale objectively, and subjectively using the faces pain rating scale (FPS).

Objective: To analyze the clinical application and limiting factors of the Hall technique (HT) preformed metal crowns in caries of primary molars and to provide reference for its clinical application based on a questionnaire survey.
Materials And Methods: From June to December 2022, a questionnaire was distributed to pediatric dentists through the WeChat platform using "Questionnaire Star" to analyze the clinical application and influencing factors of the HT preformed metal crowns in caries of primary molars.
Results: A total of 700 survey questionnaires were distributed, and 650 valid questionnaires were recovered, with a effectiveness rate of 92.
