Every ST was evaluated for its forms, morphology, position, eruption status, closeness to neighboring roots, and associated complication. The chi-square or Fisher's exact tests and multivariate logistic regression were used.

Among the most prevalent were premolars (38.8%), lateral incisors (21.4%), mesiodens, and canines (15.3% each). The mandible (19.0%) and left side (20.5%) had slightly higher ST rates than the maxilla (16.2%). The majority had impaction (73.5%), inclined position (37.8%), and supplement morphology (51.0%).
