Abstract: Objective: To evaluate the effectiveness of the Hall Technique for managing carious primary molars and discuss the influence factors correlate to the success rate through a cohort study. Methods: From March 2020 to June 2022, 31 patients (31 teeth) with carious primary molar were selected. All the molars were treated with the Hall Technique. The patients were re-examined 12 to 39 months after operation and the outcomes were evaluated by symptoms of TMJ and teeth, clinical examination, and periapical radiograph. Kaplan-Meier survival analysis was used to calculate the success rate, and influence factors correlated to the success rate were analyzed by Log-Rank test. Results: Totally thirty patients [average (4.9±1.5) years old from 3.3 to 8.2 years old,21 males and 9 females] received the follow-up examination more than 12 months. The overall success rate was 93.3% and the cumulative probability of survival at 1 year and 2 years were 96.7% and 92.3%. Age, tooth position, cavity shape, and ICDAS coronal caries lesion radiographic score had no significant correlations with the success rate (P>0.05). Conclusion: The Hall Technique was effective in treating carious primary molars. Age, tooth position, cavity shape, and the depth of caries had no significant correlations with the success rate.
