Short-term evaluation of resin sealing and rebonding on amalgam microleakage: an SEM observation.
AIMS The aim of this study was to evaluate the effect of two different sealing agents on the microleakage of Class V amalgam restorations with and without resin rebonding. METHODS AND MATERIALS Sixty extracted premolars were divided into six groups with ten teeth in each group. Class V cavity preparations were prepared on the facial surfaces of each tooth with the coronal margins placed in en...

متن کاملEnamel of primary teeth--morphological and chemical aspects.
Enamel is one of the most important structures of the tooth, both from a functional and esthetic point of view. Primary enamel carries registered information regarding metabolic and physiological events that occurred during the period around birth and the first year of life. Detailed knowledge of normal development and the structure of enamel is important for the assessment of mineralization de...
متن کاملA comparison of the marginal adaptation of retrograde techniques: a scanning electron microscopic study.
An investigation of the most popular retrograde technique for their marginal adaptation to dentin was attempted. Forty extracted maxillary central incisors were instrumented and obturated, and various apical procedures were performed. The scanning electron microscope was used to record the results. Retrograde amalgam, heat-sealed gutta-percha, and the apicoectomy control showed average marginal...
متن کاملSurface morphological changes in human enamel following bleaching: an in vitro scanning electron microscopic study.
OBJECTIVE The purpose of this study was to evaluate, using scanning electron microscopy (SEM), the morphological and structural changes of the enamel induced by three bleaching agents namely old McInnes solution, modified McInnes solution and 10% carbamide peroxide gel at different time intervals. MATERIALS AND METHODS Fifteen freshly extracted noncarious human central incisors with intact en...
