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 odder 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 65% of the cases.
