| Abstract |
|
The purpose of this study was designed to evaluate the existence of the junctional epithelia on the tooth surface in periodontal pocket, and what were the morphologic differences between the junctional epithelia on the healthy and advanced periodontitis tooth. Fifteen premolar teeth from patients of Yon Sei University, Dental Infirmary were selected for this study. After extration, the teeth were prepared and examined in Scanning electro microscope. The results were as follows. 1. The junctional epithelia from healthy tooth surface were irreguraly round, oval, polygonal and slightly elongated while those from periodontal pocket were so elongated that difficult to distinguished the individual cell boundary. 2. There were a lot of round space so called 'HOLE or WHORL' which seemed tunnel in periodontal pocket with advanced periodontitis. 3. Microvilli were going to destructed and disappeared on surfaces of junctional epithelia in periodontal pocket with advanced periodontitis. 4. There were a lot of Filopodia on Junctional epithelia from healthy surfaces. %. Junctional epithelia from periodontal pocket with advanced periodontitis contained more inflammatory cells than healthy junctional epithelia did. |
