The Analysis of Intermolar Width and Skeletal Base Class as a Predictor of Potential Maxillary Canine Impaction in Permanent Dentition: A Cross-Sectional Study.

Objectives. This study aimed to analyze the inter-molar width and skeletal base class to predict maxillary canine impaction in permanent dentition. Methods. This cross-sectional study was carried out between September 2021 to March 2022. Patients aged between 13 and 20 years were recruited. These patients' cone-beam computer tomography(CBCT), lateral cephalogram, and dental casts were collected and analyzed. For statistical analysis, T -test and Chi-square tests were applied. Results. A total of 92 patients were enrolled in this study. Inter-molar width was significantly decreased in patients with impacted canine( P  < .001). The skeletal base classification was statistically significant when compare with intermolar width( P  < .05). The location of impaction ( P  = .060), type of impaction( P  = .435), and side of impaction( P  = .239) were determined to be statistically insignificant. Conclusion. The Inter-molar width was decreased in patients with impacted canine; therefore, it may be a potential risk factor. The skeletal classification was found to affect inter-molar width in impacted canine patients.
