Orthodontic Treatment and Pulp Stone Formation: Is There a Relationship?

Abstract

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.

Pulp stones following orthodontic treatment: a case-control study

“…Assessment of presence of calcifications after orthodontic treatment, by analyzing panoramic radiographs, was performed by Ertas et al (2017), Jena et al (2018), and Korkmaz et al (2019), showed an increase in the incidence of post-treatment PS, which does not corroborate our findings.…”

“…In this study, orthodontic treatment was not associated with PS incidence. With a varied and not yet fully elucidated etiopathogenesis, orthodontic movement has proven to be a relevant factor associated with the development of PS according to other authors (ERTAS et al, 2017;JENA et al, 2018;KORKMAZ;AYDIN;SARIOGLU, 2019).…”

“…Initially, an active search was carried out for panoramic radiographs of patients who were treated at a private clinic specializing in orthodontic treatment, in Curitiba, PR, between the years 2000 and 2020 (n = 2124). Individuals of both sexes were included, aged between 14 and 26 years at the beginning of treatment (JENA et al, 2018) and who had good quality radiographic examinations in the pre-and post-orthodontic treatment periods (ERTAS et al, 2017;JENA et al, 2018;KORKMAZ;AYDIN;SARIOGLU, 2019). All patients had a record of using fixed orthodontic appliances.…”

“…In the literature, the possible causes for the occurrence of PS are trauma (LAZZARETTI et al, 2014), chronic irritations due to caries or restorative materials (ERTAS et al, 2017, SEZGIN;SÖNMEZ;KAPLAN, 2021), nanoparticles and nanobacteria (ZENG et al, 2011), systemic diseases (SATHEESHKUMAR et al, 2013;TALLA et al, 2014), and genetic factors (ERTAS et al, 2017). In this context, orthodontic movement seems to be part of the possible causes of occurrence of PS (ERTAS et al, 2017;JENA et al, 2018;KORKMAZ;AYDIN;SARIOGLU, 2019).…”

“…Several investigations focused on identifying development of PS after orthodontic treatment look into the method used to analyze panoramic radiographs (ERTAS et al, 2017;JENA et al, 2018;KORKMAZ;AYDIN;SARIOGLU, 2019), which is part of the justification for carrying out this research. Therefore, the present study aimed to investigate incidence of PS after orthodontic treatment in patients attending a private clinic in Curitiba, PR, Brazil.…”
