Anterior interdental space and dental rotation are of great importance, as far as bite injury or dental mark as criminal evidences on site are concerned, and different interracially. Here is presented the interracial comparative study of anterior interdental space and Winging status with impression taken in Ghana in March 1996. The subjects comprised 197 male and 187 female inhabitants in Ghana between 15-39 years of age. Interdental space was taken to be that more than 1 mm by inspection. Winging was determined by Dahlberg's classification. Of 384, interdental spaces were identified in 182 (47.4 %), more than 36.5 % in the Japanese. As for region, maxillary intercentral incisor spaces were most frequently revealed (28.9 %), and bilateral spaces between mandibular lateral incisor and canine amounted to 26.1%. Median mandibular spaces were found in 11.5%, more than 1.3% in the Japanese. One space per one jaw amounted to 12.5% in maxilla and 7.6% in mandible, both were the most frequent. With interdental space existing, both the length and width of anterior dental arch were increased in the Ghanaian, as oppose to only length increment in the Japanese. Bilateral Winging was shown to be 13.8% more than 3.0% in the American White and 9.7% in the Japanese.
