The author examined bone changes from 1274 polytomographic images of 182
temporomandibular joints which showed symptoms of temporomandibular disorder and
the fallowing results were obtained;
1. The number of temporomandibular joints which showed bone changes were 64
(35.2%) among 182 joints.
2. The age and sex distribution of 64 joints which had bone changes showed the
prevalence of female (90.6%) and third decade (25.0%) followed by fourth (21.2%) and
second decade (17.2%).
3. The 252 images which showed bone changes consisted of 56 images from lateral
side (22.2%), 118 images from center (46.8%) and 78 images from medial side (30.9%).
4. The most frequently observed bone changes were flattening (22.7%) fallowed by
sclerosis (19.3%) and cortical unsharpness (19.3%)
