아래턱뼈의 질적, 양적 상태를 알 수 있는 형태계측적 자료는 턱을 시술할 때 매우 중요하며, 아래턱뼈의 뼈상태를 예측할 수 있다면 임상적으로 유용하게 활용할 수 있다. 이에 저자들은 아래턱뼈에서 치아유무에 따라 아래턱뼈 단면에서 나타나는 겉질뼈와 해면뼈의 두께, 아래턱뼈 뼈밀도를 측정하여 형태계측적자료를 제공하기 위해 본 연구를 실시하였다. 한양대학교 의과대학 해부∙세포생물학교실에 고정된 시신 61구의 아래턱뼈(남자 32구, 여자 29구, 평균나이66.72세)에서 턱뼈각, 작은어금니와 큰어금니 사이, 앞니부위, 아래턱뼈 전체의 뼈밀도를 이중 에너지 방사선 흡수계측기(dual energy X-ray absorptiometry)로 측정하고, 첫째와 둘째큰어금니를 지나는 아래턱뼈의 단면에서 11가지 항목의 뼈두께와 길이를 계측하여 남녀, 연령별, 치아유무에 따라 나누어 SPSS 12.0 프로그램의 One-Way ANOVA를 이용하여 통계적 유의성을 검증하고 상관관계를 분석하여 다음과 같은 결과를 얻었다. 아래턱뼈에서 뼈밀도는 위치마다 차이가 있었고, 아래턱뼈에서 뼈밀도는 겉질뼈의 뼈두께와 상관관계가 높았으며, 가장 높은 것은 볼쪽과 혀쪽 겉질뼈 두께의 합(상관계수 r=0.622)이었다. 아래턱뼈 단면에서 겉질뼈의 두께는 남자가 여자보다 유의하게 컸으나 어금니 주변의 뼈밀도와 뼈두께 사이의 상관계수는 여성에서 더욱 크게나타났다. 아래턱뼈에서 아래턱 전체 뼈밀도, 혀쪽 겉질뼈 두께, 바닥쪽 겉질뼈 두께와 이틀돌기의 높이는 큰어금니가 모두 있는 경우에 통계적으로 의미 있게 컸다. 이상의 결과를 종합하면 아래턱뼈의 뼈밀도는 성별, 연령, 치아유무에 따라 차이가 있었으며, 아래턱 겉질뼈의두께와 상관관계가 높은 것을 알 수 있었다.
Abstract
The morphometric data which reflect the quality and quantity of the mandible are very important to the surgeon for the mandible. It is very useful clinically to predict the status of the mandible indirectly by other medical examinations. This study was undertaken to clarify the correlations of the mandible and dentition to predict the thickness and bone mineral density of the mandible. Sixty-one mandibles (32 M/29 F, mean age: 66.72 years) obtained from the collection of the Department of Anatomy and Cell Biology of Hanyang Medical College were analyzed. The bone mineral density was measured by dual energy X-ray absorptiometry. In the mandible, bone mineral densities at the mandiblular angle, between molars and premolars, around incisors and the thickness, and the length at the sections through the 1st and the 2nd molars were measured. The data were analysed with SPSS 12.0 program (One-Way ANOVA) according to age, gender and dentition,to verify the statistical significance and the correlation between the thickness and bone mineral densities. The obtained results were as follows. 1. The bone mineral density in the mandibular areas were variable, but statistically insignificant except incisor area. The bone density of the mandible was highly correlated with the thickness of cortical bones and the highest correlation coefficient was shown in sum of the thickness of buccal and lingual cortical bone (correlation coefficient,r=0.622)2. The thickness of cortical bones at the sections through the molars in the man were greater than those in the woman. The correlation coefficient between the thickness and bone mineral density at the molars were greater in the woman. 3. The bone mineral density of whole mandible, the thickness of lingual and basal cortical bones and the height of alveolar ridge were significantly higher in the specimens with both of the 1st and 2nd mandibular molar teeth. The results of this study represents the significant differences of bone mineral density in the mandible according to gender and dentition and also the significant correlation between the bone mineral density and the thickness of cortical bone.
