Risk Factors of Root Canal Treatment Among Children with Irreversible Pulpitis in Primary Molar: A Retrospective Study

doi:10.13701/j.cnki.kqyxyj.2024.12.007

Abstract

Abstract: Objective: To explore the risk factors and evaluate survival rates in patients undergoing root canal treatment for irreversible pulpitis in primary molars under local anesthesia through clinical follow-up data. Methods: Clinical follow-up data of patients aged 3-8 years old diagnosed with irreversible pulpitis and treated with root canal therapy on primary molars between April 2018 and June 2022 at the Children's Stomatology Department of Hefei Stomatology Hospital were collected. Kaplan-Meier method and Cox regression analysis were employed for survival analysis. Results: A total of 255 patients with 377 primary molars were included in the study. It was found that the older the children, the greater the risk of treatment failure(hazard ratio: 1.688, 95% confidence interval: 1.059 - 1.889). Maxillary primary molars had a higher success rate compared to mandibular primary molars. Glass ionomer cement (GIC) filling was associated with a higher failure risk, while differences in success rates were not statistically significant in treatment times and gender (P>0.05). Conclusion: Age, tooth position, and restoration materials are important factors affecting the success rate of root canal treatment in deciduous molar teeth.
