Could idiopathic osteosclerosis have correlations with palatally impacted maxillary canines?

Abstract

Aim: To investigate the association between palatally impacted maxillary canines (PIC) and idiopathic osteosclerosis. Methods: A sample of 54 subjects (28 females and 26 males, mean age of 12.98±1.59 years) with PIC was selected from the records of 1,650 orthodontic patients treated at the Discipline of Orthodontics clinics at the Dental School of the Pontifical Catholic University of Paraná (PUCPR), in Curitiba, PR, Brazil. A control group of 54 subjects with normally erupted canines was also selected from the same files (mean age of 12.93±1.58 years). Panoramic, lateral skull, postero-anterior skull, periapical and occlusal radiographs, as well as stone casts of the patients were examined. The Kolmogorov-Smirnov test revealed a normal distribution of gender and age in the groups. The results were analyzed with the Chi-square test (α=0.05). Results: There were no statistically significant differences (p>0.05) between the groups. Four patients from each group had idiopathic osteosclerosis (7.41%), a rate that falls in the prevalence range reported in the literature. Conclusions: No correlation was observed between palatally impacted maxillary canines and idiopathic osteosclerosis.

Idiopathic osteosclerosis mimicry of a tooth: case report

“…Marques‐Silva et al claimed that idiopathic osteosclerosis may cause changes in tooth position or problems during orthodontic treatment, and reported a case of tooth resorption caused by ectopic eruption rote caused by idiopathic osteosclerosis 14 . However, idiopathic osteosclerosis is usually considered a developmental variation of normal bone architecture unrelated to local stimuli, 1,5,8,13 a viewpoint with which the authors of the present study agree.…”

“…7 However, the incidence of IO has no correlation with other dental anomalies such as palatally impacted canine. 8 We report the unusual cases of two orthodontic patients who presented with idiopathic osteosclerosis which mimicked a buccally impacted canine and a retained root, respectively.…”
