RELATIONSHIP OF PALATALLY IMPACTED CANINE WITH SKELETAL AND DENTAL ANOMALIES IN ORTHODONTIC PATIENTS

Abstract

Objective: To determine the relationship of palatally impacted canine with skeletal and dental anomalies in orthodontic patients.

Material and Methods: This retrospective study involved a total of 94 participants, with 47 cases with PICs and 47 controls. The inclusion criteria were high-quality orthodontic radiographs including lateral cephalograms and panoramic radiographs and dental casts. Exclusion criteria involved patients with incomplete orthodontic records, medical pathologies, syndromes, history of head and neck radiotherapy or surgery, and previous orthodontic treatment. The dental anomalies investigated in this study focused on upper lateral incisor anomalies, while skeletal anomalies included sella turcica bridging and ponticulus posticus. The extent of sella turcica bridging and ponticulus posticus was evaluated using a standardized scoring system developed by Leonardi et al. Association was determined using the Chi-square test.

Results: The mean age of the participants in this study was 27.30±7.14 years. Among the cases, there were 28 females (59.57%), while among the controls, there were 27 females (57.45%). Significant associations were found between sella turcica bridging and maxillary impacted canine (p = 0.005), indicating a strong relationship. Additionally, there was a marginally significant association between ponticulus posticus and maxillary impacted canine (p = 0.042), suggesting a weaker but still noteworthy association. On the other hand, the association between anomalous lateral incisors and palatally impacted canine did not reach statistical significance.

Conclusion: There is a significant association of the bridging of sella turcica and ponticulus posticus with palatal canine impaction. However, no statistical association was found between anomalous lateral incisor and palatal impaction of canine.
