Aim:
To clinically and radiographically assess the efficacy of photodynamic therapy (PDT) as a novel technique in the root canal treatment (RCT) of primary molars.
Materials And Methods:
Sixty primary mandibular molars were selected from children aged between 4 and 7 years, each presenting with clinical and radiographic criteria of pulpal necrosis. They were randomly divided into three groups (n = 20): Group I-conventional RCT; group II-PDT; and group III-modified PDT. Participants underwent clinical and radiographic assessments over a 15-month follow-up period at 5-month intervals (5, 10, and 15 months). The results were analyzed using the Chi-square test with a level of significance set at p < 0.05.
Results:
Considering the clinical and radiographic success, no statistically significant difference (p > 0.05) was found between the three groups during the follow-up periods. However, PDT and Modified PDT groups showed less root resorption with a statistically significant difference (p < 0.05) with the RCT group at the end of the 15-month follow-up period.
Conclusion:
Photodynamic therapy and modified PDT showed effective and comparable clinical and radiographic outcomes to those of conventional root canal therapy in primary molars.
Clinical Significance:
Photodynamic therapy can be effectively utilized in the endodontic treatment of primary teeth through simple and minimally time-consuming procedures, making it particularly suitable for children.
