ABSTRACT
Aim: To investigate the association between palatally impacted maxillary canines (PIC) andidiopathic osteosclerosis. Methods: A sample of 54 subjects (28 females and 26 males, mean ageof 12.98±1.59 years) with PIC was selected from the records of 1,650 orthodontic patients treatedat the Discipline of Orthodontics clinics at the Dental School of the Pontifical Catholic University ofParaná (PUCPR), in Curitiba, PR, Brazil. A control group of 54 subjects with normally eruptedcanines 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 ofthe patients were examined. The Kolmogorov-Smirnov test revealed a normal distribution ofgender 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. Fourpatients from each group had idiopathic osteosclerosis (7.41%), a rate that falls in the prevalencerange reported in the literature. Conclusions: No correlation was observed between palatallyimpacted maxillary canines and idiopathic osteosclerosis.
