The purpose of this study was to evaluate the incidence and several radiographic features of dilacerated teeth in 2132 full month radiograms in Korean. The results were as follows: 1. The occurrence was revealed to 2.7% in total examined teeth, and these anomalies were occurred in maxilla (52.4%) more than in mandible (47.6%). 2. There was a predilection for occurrence of dilaceration in female, which included 12.8% of the female compared to 11.3% in male. 3. The frequency of dilaceration in male, which included 40.5% in maxilla and 59.5% in mandible. The frequency of dilaceration in female, which included 52.4% in maxilla and 47.6% in mandible. 4. The order of frequency of dilaceration was second premolar, first premolar, lateral incisor, canine in maxilla, and first premolar, second premolar, canine, lateral incisor, central incisor in mandible. 5. In classifying of dilacerated teeth into 3 types by following appearances such as root curvature. Distal dilaceration was by far most common containing 65.8% of the cases. The least frequent was mesial dilaceration, which included 6.5% of the cases.
