Comparison of scanning and transmission electron microscopy of the epithelial pocket wall in juvenile and XXXX .

@entity1 @entity32 @entity6730 @entity7278 @entity6223 @entity79 @entity258
Using scanning (SEM) and transmission (TEM) electron microscopy, this study compared fine structural features of the pocket walls in both juvenile and @entity7278 ( @entity6223 and AP, respectively) in 40 cases. Gingiva was also obtained from a control group consisting of periodontally noninvolved teeth. Clinical parameters were assessed in both @entity6223 and AP @entity1 as well as in controls. Clinical findings showed @entity258 , marked periodontal tissue destruction and less @entity32 in @entity6223 . @entity79 and @entity6730 were more marked in @entity6223 than in AP. AP had a higher plaque index and more evident @entity32 . SEM observations of @entity6223 as compared to AP showed gross distortions in pocket walls, an increased beaded appearance of microridges, and separation between pocket epithelial cells. TEM showed partially desquamated and separated superficial epithelial cells, but only in @entity6223 were fine granular precipitates observed in the intercellular spaces. The observations demonstrated structural features indicative of more prominent degenerative changes in @entity6223 than in AP. Also, these features were coincidental with a higher plaque index in AP than in @entity6223 , where clinical features (including a low plaque index) were not proportional to the epithelial destructive changes present.
