many investigators use bone matrix gelatin for bone induction but it is used rarely for repair of teeth defects. this study was designed to evaluate secondary dentin formation by endochondral bone matrix gelatin (e-bmg) in rabbit. e-bmg was prepared from tibia and femur of 4 deutsche-poland rabbits with average ages of 4-6 months. the prepared e-bmg was implanted in right incisor teeth pulps of...

OBJECTIVES The present study evaluated the microtensile bond strength and caries formation on adhesive/dentin interfaces before and after dynamic chemical formation of secondary caries. METHODS Restorations were prepared on the dentin surface of 80 bovine incisors using four adhesive systems: two fluoride-free (Single Bond and Clearfil SE Bond) and two fluoride containing (Optibond Solo Plus ...

According to LESTER and BOYDE [1], the VON KORFF fibers which were described in detail by VON KORFF in 1905 were later confirmed by WEIDENREICH in 1925 in connection with the formation of mantle dentin but they were not observed at the stage of circumpulpal dentin formation. These findings of WEIDENREICH have been endorsed by recent studies using the electron microscopy [1, 2, 3]. However, opin...

This study evaluated the histological pulp responses of four different adhesive resin systems placed directly on exposed pulp tissue. Gap formation between the respective resin and cavity walls was observed and correlated to the pulpal response. Occlusal cavity preparations creating mechanical pulp exposures were prepared in molars of wistar rats. Preparations were filled using one of the follo...

The most visible repair response to pulp injury is the deposition of a tertiary dentin matrix over the dentinal tubules of the primary or secondary dentin. Tertiary dentin is distinguished as reactionary and reparative dentin, depending on the severity of the initiating response and the conditions under which the newly deposited dentin matrix was elaborated. Transforming growth factor beta (TGF...

Introduction: Dentin dysplasia is a rare autosomal dominant inheriting disturbance of dentin formation characterized by normal enamel formation, but atypical dentin with abnormal pulpal morphology. There are two major patterns: type I and type II. Amelogenesis imperfecta is an autosomal dominant. X-link inherent disease that is classified by clinical manifestation into hypoplastic, hyp...
