A scanning electron microscopic study of dentinal tubules in dead tracts.
It is generally accepted that a certain change occurs in teeth containing a vital pulp as a response to such injuries as caries, attrition and abrasion. In these cases dentinal tubules are filled with gaseous substances. In ground sections the groups of dentinal tubules, appearing black in transmitted light, have been named dead tracts by FisH[1-3]. However, there are few reports on the observa...
متن کاملDentinal tubules at the root ends of apicected teeth: a scanning electron microscopic study.
Two groups of teeth, one of which contained teeth of known age, were examined by scanning electron microscopy to ascertain the presence of a potential pathway for leakage at the root ends of apicected teeth. At a point approximately 3 mm from the apex, a level chosen as being typical for apicectomy, and half-way between the root canal and the dentine-cementum junction, there were found to be, o...
متن کاملScanning electron microscopic evaluation of dentinal tubule penetration of Epiphany in severely curved root canals
OBJECTIVE The purpose of this study was to compare the depth of dentinal tubule sealer penetration in the apical thirds of severely curved root canals obturated with Resilon/Epiphany self-etch (SE) or gutta-percha/AH Plus using scanning electron microscopy. MATERIALS AND METHODS A total of 34 extracted human mandibular molars with 25-40° curvature of the mesial root canal were selected for th...
متن کاملScanning electron microscopic study of dentinal pulpal walls in relation to age and tooth area.
A study was conducted to observe the surface morphological changes of human dentinal pulpal walls in specific areas of the tooth at various ages. Thirty-two extracted human non-carious teeth with single root canals were used. The teeth were divided longitudinally in the bucco-lingual plane and prepared for scanning electron microscopy (SEM). The specimens were divided into two groups (younger a...
متن کاملScanning Electron Microscopic Analyses of the Effects of Different Disinfectant Methods on Dentinal Structure
The purpose of this study was to evaluate the prepared dentin surface and to determine whether or not it is possible to seal the dentinal tubules, after different cavity disinfectant applications. Thirty mandibular molars were sectioned parallel to the occlusal plane to expose the midcoronal dentin. All of the teeth were divided into five groups (n = 6 per group): (1) in group OZ, the dentin su...
