| Abstract |
|
Authors have made a study on the prevalence of the dental caries of distal surface of the lower 2nd molar adjacent to the lower wisdom tooth turned anteriorly. The total number examined was 893 including 542 cases of male and 351 cases of female from the 10s to the 60s. This was taken from the diagnostic charts and intraoral standard films in the infirmary of the college of dentistry, Seoul National University from Jan. 1974 to Aug. 1976. The results are as follows: 1. The caries incidence rate in male was higher than that of female (p<0.01), but the difference between right side and left side was not significant statistically(p>0.1). 3. The Incidence rate of the periapical lesions considered by dental caries of the distal surface of the lower 2nd molar was 3.9%. |
