Comparative evaluation of NovaMin desensitizer and Gluma desensitizer on dentinal tubule occlusion: a scanning electron microscopic study
PURPOSE In this study, the effect of calcium sodium phosphosilicate (NovaMin) desensitizing agent, which is a powder-based system, and hydroxyethyl methacrylate and glutaraldehyde (Gluma desensitizer), which is liquid-based system, on dentinal tubule occlusion was analyzed by scanning electron microscope. The effects of the above two along with one control group were compared to determine the m...
متن کاملEffects of desensitizing agents on dentinal tubule occlusion.
The aim of this study was to evaluate the features of dentinal tubules occlusion following application of three commercially available desensitizing agents: potassium oxalate-based / Oxa-Gel (OX), HEMA and glutaraldehyde-based / Gluma Desensitizer (GD) and acidulated phosphate fluoride-based / Nupro Gel (AF). Buccal cervical areas of twenty-four extracted human third molars were smoothed and we...
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 کاملIn vitro and in vivo analyses of the effects of desensitizing agents on dentin permeability and dentinal tubule occlusion.
This study was done to assess the influence of the topical application of two different desensitizing agents on dentin permeability and dentinal tubule occlusion. Twenty-one rats provided 84 teeth: 36 for the in vitro and 48 for the in vivo investigation. The following agents were tested: Group 1, 2% potassium nitrate plus 2% sodium fluoride gel; Group 2, 5% sodium fluoride varnish; Group 3, 3%...
متن کاملA 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...
