Objectives: This study aims to evaluate the relationship between follicular width, apical development, and angulation of impacted maxillary canines and the resorption of adjacent teeth.
Methods: 3D CBCT images of 127 patients were analyzed. Maxillary canine apical development was classified using the Demirjian chart. Follicular widths and angles between impacted canines, the midpalatal suture, and resorbed adjacent teeth were measured. Resorption severity in lateral incisors, central incisors, premolars, and deciduous canines was compared.
Results: Impacted canines were more prevalent in females (62.2%). Premolar resorption was more common in males (52.6%), whereas resorption of lateral incisors (66.4%), central incisors (64.9%), and deciduous canines (51.4%) was more frequent in females. Central incisors (24.3%) and premolars (26.3%) exhibited higher rates of absent resorption, while severe resorption was most common in deciduous canines (62.9%).
Follicular width did not significantly impact resorption severity in central incisors, lateral incisors, or premolars (p > 0.05). However, a significant positive relationship was observed between follicular width and resorption severity in deciduous canines (p < 0.05). Positive correlations were identified between the canine-midline angle and the angles of adjacent lateral, central, and deciduous canines (p < 0.001). The canine-premolar angle was not significantly correlated with the canine-midline angle (p > 0.05).
A significant negative relationship between the canine-premolar angle and resorption severity (p < 0.05) suggests that increased angles may reduce resorption risks. No significant correlations were noted between resorption severity and angles of lateral incisors, central incisors, or deciduous canines (p > 0.05).
Conclusions: Follicular width influences resorption severity in deciduous canines. Angular relationships, particularly the canine-midline angle, play a critical role in assessing impacted canines. Certain angular configurations, such as a larger canine-premolar angle, may reduce resorption risks, offering valuable insights for clinical treatment planning.
