Frequency of posterior teeth that presented with pulpal calcifications after orthodontic treatment; a retrospective radiographic assessment.

Abstract

Objective: To assess the pulpal calcification that was presented on radiographs after the completion of orthodontic treatment. Study Design: Retrospective Observational study. Setting: Department of Orthodontic, Ayub Medical College Abbottabad. Period: October 2023 to November 2023. Methods: Following the inclusion and exclusion criteria, the current study was carried out on patients who had reported and registered for orthodontic intervention within the previous five years and had case records from the orthodontics department available. A total of 670 case records were assessed for selecting 191 cases as per sample size. Results: Among 191 patients, 30.4% were male and 69.6% were female. The highest percentage belonged to the 14-16 age group (32%), followed by 20-22 (28.3%), 17-19 (26.2%), and 23-25 (12.6%) age groups. Pre-treatment calcification was 17.8% (n=34), rising to 28.3% (n=54) post-treatment. Pulp calcification significantly increased after orthodontic treatment (p<0.05). No significant differences were found between gender and age groups regarding pulp calcification (p>0.05). However, a significant association existed between pulp calcification and treatment duration (p<0.05). The 25-30 months treatment duration had the highest occurrence (n=27), followed by 31-36 months (n=19). Mandibular teeth had a higher prevalence of pulp calcification (53.7%) than maxillary teeth (46.3%), with tooth number 36 having the highest prevalence (25.9%). A significant relationship was observed between the left and right sides of the dental arches, with the left side exhibiting greater tooth calcification (68.5%) than the right side (31.5%). Conclusions: The present study concluded that there was an increase in the frequency of pulpal calcifications in the observed posterior teeth after orthodontic treatment. Pulpal calcifications were significantly more prevalent in the posterior teeth of the mandibular arch compared to the maxillary arch. Moreover, the likelihood of pulpal calcification increased over the duration of orthodontic treatment.
