成年型牙周炎大臼齒區鄰接面齒槽骨破壞量之研究
A Cross – Sectional Radiographic Study of Proximal Alveolar Bone Loss in Molars with Adult Periodontitis
摘要
本研究樣本由高雄醫院附設中和紀念醫院牙科門診部牙周病科，收集1992年1月到1994年6月間所有以標準平行法所拍攝的全口根尖X光片，以219名20~65歲的成人型牙周炎患者為研究對象，透過幻燈機將X光片放大20*20倍後，針對大臼齒區鄰接面之齒槽骨破壞情形進行探討。結果顯示：1.上顎第一、二大臼齒的平均鄰接面齒槽骨破壞量分別為38.4%與33.5%。下顎第一、二大臼齒的平均鄰接面齒槽骨破壞量則為34.8%與31.6%。除下顎第一大臼齒外，其它三組大臼齒的平均鄰接面齒槽骨破壞量皆會隨年齡的增加而有顯著的增加。2.不論是上顎或下顎，皆以第一大臼齒平均鄰接面齒槽骨破壞量顯著大於第二大臼齒。上顎第一大臼齒平均鄰接面齒槽骨破壞顯顯著大於下顎第一大臼齒；上、下顎第二大臼齒的平均鄰接面齒槽骨破壞量則無差異性存在。3.右側及左側齒弓，皆以第一大臼齒的平均鄰接面齒槽骨破壞量顯著大於第二大臼齒。而左、右兩側的大臼齒間平均齒槽骨破壞量則無顯著差異。4.四組大臼齒中，以上顎第一大臼齒的近心面平均齒槽骨的破壞量最大（39.4%）；下顎第二大臼齒的遠心面破壞量最小（31.5%）。不論男、女性，皆以下顎第一大臼齒的遠心面平均齒槽骨破壞量顯著大於近心面，其它的大臼齒近、遠心面間齒槽骨的高度閱無差異性存在。

The purpose of the present study was to document the mean proximal alveolar bone loss of molars. The samples consisted of 219 subjects receiving of full mouth radiographs by standardized paralleling technique from Jan, 1992 to Jun, 1994. All the radiographs of 219 individuals suffered from adult periodontitis at age between 20 and 65 years old were measured, and were assessed mean proximal alveolar bone loss of molars and associated contributing factors. The main results indicated that (1) the mean proximal alveolar bone loss of the maxillary first and second molars accounted for 38. 4% and 33.5%, respectively, whereas the mardibular first and second molars were 34.8% and 31.6%, respectively; (2) within the same dental arch, mean proximal alveolar bone loss of the first molars was significant greater than that of the second molars, while the bone loss in the maxillary first molars was significant greater than that of the mandibular first molars. There was no difference between mean proximal bone loss of the maxillary and mandibular second molars; (3) mean alveolar bone loss of the first molars was significant greater than second molars in the same side of the dental arch. There was no significant difference in the mean proximal alveolar bone loss between right and left side molars. (4) average bone loss was the greatest (39.4%) at the mesial surfaces of maxillary first molars, whereas the least mean alveolar bone loss appeared at the distal surfaces of mandibular second molars. A significant difference of mean proximal alveolar bone loss was found between mesial and distal surfaces in mandibular first molars.
