• 中文摘要： 本研究目的乃在探討及比較流血與不流血牙齦上皮下浸潤結締組織體積之異同；並與立體顯微鏡檢查之結果比較、分析其中之關係。本實驗材料源自三十三位患者共五十一例牙齦標本，先以立體顯微鏡檢視，再經組織處理後以光學顯微鏡觀察上皮下浸潤結締組織之體積。結果顯示流血牙齦浸潤結締組織之體積顯著較不流血牙齦為大，但浸潤結締組織體積之差異卻與牙齦溝側表面血管之立體顯微鏡觀察結果無關。由此可知增加浸潤結締組織體積反映在臨床上可預測牙齦將有探測流血之結果，但卻與立體顯微鏡下之血管表現無關。
• 英文摘要： The present study was carried out to evaluate and compare the volumetric densities of subepithelialinfiltrated connective tissue (ICT) geographically in bleeding and non-bleeding gingivae with specialreference to comparisons of the relationships with their corresponding stereomicroscopic findings. A totalof 51 biopsies (25 bleeding and 26 non-bleeding gingival specimens) was obtained from 33 patients. Afterstereomicroscopic examinations, tissue sections were obtained with H&E stain. On each section, the densityof ICT was calculated by volumetric analysis. The results showed that the volume of ICT in bleeding.gingiva was significantly greater than that in non-bleeding gingiva. However, there was no specific relation-ship between the ICT of gingiva and the visibility of vasculature by stereomicroscopy. These results suggestthat increased infiltrated inflammatory volumes of gingiva may play a role in the presenting of bleedingon clinical probing, but appear not to be related to the visibility of vasculature by stereomicroscopy.
