TI  - The Quantitative Method for Following Radiologic Healing in Endodontic Retreatment; 1-Year Follow-up Study
AB  - Objectives: This study aimed to quantitatively evaluate the changes in the internal bone structure at the periapical bone regions after retreatment in endodontics using fractal analysis method on periapical radiographs. Materials and Methods: In this retrospective study, 29 single-rooted, asymptomatic, single-visit retreatment teeth with apical lesion were included. All teeth included in the study were selected from the maxilla anterior region. Periapical radiograph (T0) was taken for baseline diagnosis at the start of retreatment. Second periapical follow-up radiograph (T1) of the patients was taken at the end of 1 year. The first evaluation phase of the 1-year results of endodontic retreatment is based on the periapical index (PAI). Fractal dimension (FD) was calculated by box-counting method. Comparing T0 and T1 FDs was done using the paired-sample t-test. To compare FD changes between the gender, the independent samples t-test was used. The significance level was set to 0.05. Results: PAI scores were found to be statistically significantly decreased in T1 radiographs compared to T0 (p<0.001). The mean FD value increased statistically significantly in T1 radiographs compared to T0 radiographs (p<0.001). No significant difference was found in the T0 and T1 radiographs of FDs in gender comparison (p>0.05). Conclusion: At the end of the 1-year follow-up, FD increased in the periapical lesion area, which is interpreted as the healing of the lesions. Fractal analysis is recommended as a method that will benefit clinicians in the follow-up of retreatment recovery.
