[A comparison of whole- and partial-mouth recording methods in an epidemiological survey of periodontal disease].

This study was performed to examine the relationship between the partial recording method of six representative teeth by Ramfjord and the entire dentition recording method for pocket depth, remaining bone level and tooth mobility. Subjects were 150 periodontal patients aged 18 to 62, averaged 36.3 years, 59 males 91 females, who visited our hospital from 1982 to 1984. Moreover the relationship between the mean of each group (7 6 6 7, 5 4 4 5, 3 3, 2 1 1 2, 7 6 6 7, 5 4 4 5, 3 3, 2 1 1 2) and the mean of the represantative individial tooth in each group was assessed. From the fact described above the following results were gained in this study. 1. Statistically significant difference was not observed between the six selected teeth discribed by Ramfjord and the entire dentition for every items. 2. Statistically singificant difference was not observed between the mean of the each group and the mean of the represantative tooth in each group. 3. Ramfjord's method was a reliable partial recoding method, and if the represantative tooth was missing in each group another tooth was avaiable for the represantative tooth.
