| Research Abstract |
In order to evaluate and establish the evidence concerned to the morphological characteristics around the mouth in Japanese, the basic methodology was discussed among the investigators. According to the basic standard, a questionnaire, intraoral and occlusal examinations and standardized facial photographs of general people, students, doctors, staffs and patients were taken in ten universities as the basic materials, respectively (Total number of data were around four thousands). Many defined lengths angles and its proportions on the facial photographs were measured using the customized cephalometric computer software. The measured data were analyzed statistically and basic statistic data base using a large group sample in Japanese were established. The relation among the results of the basic examination, the intraoral and occlusal examinations and the measurements concerned about the standardized facial photographs were investigated and evaluated.
As a results of these investigations, reliable data base of morphological standards in Japanese were established. The basic statistical data about the morphological characteristics around the mouth clearly revealed the characteristics in Japanese (For example: concave or straight profile type as a skeletal class III tendency or protrusion around the mouth as bialveolar protrusions). The difference between the data of the general group and the dental concerned group was not existed except the experiences about orthodontic treatment.
