 note = {application/pdf, The statistical analysis of district distribution, number, and type of malocclusion in orthodontic patients at Matsumoto Dental College Hospital has been reported upon every five years during the period from 1972 to 1986. The current study analysed records of the most recent five year period of January 1986 through December 1991 and then compared the findings with those of previous reports. The results obtained were as follows: 1. 942 patients, consisting of 344 males and 598 females were examined to show a 4:6 ratio of males to female. 2. The district distribution of patients showed that most patients came from the local area to our clinic. 3. The number of patients were almost equal to that of the previous five years. 4. The number of patients was highest in the month of March. 5. With regards to the distribution of malocclusion types, the percentage of mandibular protrusion and anterior crowding increased for both sexes. This trend was also observed in previous reports. 6. The age distribution showed that more than 30% of the total number of patients were pupils between 9 and 11 years old. 7. In the present survey, females were more than males in all age groups. Also, the second peak of patient's increase was observed in older than 15 years paticularly in females.},
