The geographical distribution, the number, and the type of malocclusion of orthodontic patients was statistically analyzed from patient records covering a five year period from January 1977 to December 1981, following a previous report (part 1). The following results were obtained: 1. The number of patients totaled 623, consisting of 210 male and 413 female patients. The ratio of male to female was ronghly 1:2. 2. The present geographic distribution of patients showed that more patients came from areas closer to the hospital. 3. The number of patients has been increasing irregularly for 5 years. 4. The average number of patients for each month was highest in the order of September, March, October, May and June. 5. In the type of malocclusions, it was indicated that anterior crowding is the remarkable increasing tendency in both males and females. 6. In terms of the different age groups of patients, 6～11 year old school children continned to comprise about 60% of the total number of patients, as found in the part 1 report. 7. More female patients than males were observed in all different age groups. An increased number of both males and females over 15 years old patients was seen. 8.
