 AB : The author had measured the alveolar bone level of periodontal disease on 50 cases of orthopantomogram to detect the degree of alveolar bone resorption of both sexes of Korean.
 The results were obtained as follows;
 1. Alveolar bone resorption of mesial and distal portion was similar in same patient.
 2. The order of alveolar bone resorption was mandibular anterior region, posterior region, canine and premolar region of both jaws.
 3. The degree of alveolar bone destruction was severe in shorter root length than longer one.
 4. The degree of alveolar bone resorption was severe in fourth decades.
