Abstract

著者는 嶺牙周團組織疾患患者 200例를 對象으로 計測用 Grid를 附着하여 全顎撮影한 口
內 X-線寫眞像을 年齡 및 性別齒牙部位에 따른 齒槽骨吸收度를 撮影하여 다음과 같은 結
論을 얻었다.
1. 同一한 患者(同人)의 上下顎骨에 있어서 齒牙別齒槽骨吸收度는 一般的으로 相違하였
다.
2. 上下顎各各前領部의 齒槽骨吸收度는 臼齒部의 齒槽骨吸收度보다 甚하였다.
3. 性別에 있어서 男性이 女性보다 齒槽骨吸收度가 甚한 傾向을 보였다.
4. 齒槽骨吸收度는 年齡의 增加에 따라 甚하였고 50代에서 가장 甚하였다.
5. 計測用 Grid를 口內標準필림에 附着시켜 撮影하여도 像은 鮮明하였으며 길이 計測에
利點이 있었다.
#초록#
The author had performed the measurement of the various teeth regions on 200 cases
of Full-mouth roentgenogram taken with the measurable Grid to detect the degree of
alveolar tone resorption, aged from 20 to 60 years of Koreans and to verify the effective
result of measurable Grid as a new device which enables the observers to determine the
correct length of images on the periapical standard film.
The results were obtained as follows.
1. It was found that the degrees of alveolar bone resorption were different in the
various teeth regions.
2. As a whole, alvolar bone resorption of anterior teeth regions was more severe than
that of posterior teeth regions.
3. Alveolar bone resorption of mandibular region was more severe than that of
maxillary region.
4. In sex difference, alveolar bone resorption of male is more severe than that of
female and it was increased with aging.
5. Measurable grid can be used as an adjunct of evaluation of alveolar bone resorption
and of calculating the tooth length.
