Abstract
Objective: The aim of this retrospective study was to evaluate the effect of orthodontic treatment on pulp stone formation.Methods: The sample population comprised 504 patients (182 males, 312 females) with a mean age of 17.7 ± 2.9 years that underwent orthodontic treatment. The pre-treatment and post-treatment panoramic radiographs of the patients were evaluated to detect pulp stones before and after orthodontic treatment. The data were analyzed using Mc Nemar, Chi-square and Fisher Exact tests.Results: The statistical analysis showed that pulp stone numbers increased significantly after treatment (p˂0.05) and there was no statistically significant difference between the sexes in terms of pulp stone enhancement. The increment of pulp stone numbers after treatment was found to be significantly higher in molars than other teeth (p˂0.05). In canine teeth, the increase in pulp stones was statistically higher in females than in males (p˂0.05).Conclusion: The results of this study showed that pulp stone numbers increased at different percentages after orthodontic treatment in all tooth groups. It may be concluded that orthodontic treatment can affect calcification metabolism of the pulp and orthodontic forces may increase pulp stone formation.
