Clinical Efficacy of Carious Primary Molars Treated with Hall Technique
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 fe-males]received the follow-up examination more than 12 months.The overall success rate was 93.3%and the cu-mulative 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.
