Objective To evaluate solubility and sealing ability of Mineral Trioxide Aggregate (MTA) and root-end filling materials. Material and Methods The materials evaluated were: MTA, Calcium Silicate Cement with zirconium oxide (CSC/ZrO2), and zinc oxide/eugenol (ZOE). Solubility test was performed according to ANSI/ADA. The difference between initial and final mass of the materials was analyzed afte...

The most commonly prescribed medication for autoimmune disorders is Azathioprine (AZA), which negatively affects renal function and tissue structure. aim of this work was to measure the therapeutic impact Zingiber officinale L. extract (ZOE) on improving structure AZA-induced damaged tissue.
 Methods: 70 rats with a weight range 200±10 g an age 95±5 days were chosen experimental study. ani...

OBJECTIVE Zinc oxide eugenol (ZOE) under composite restorations should be covered with a suitable material in order to prevent the harmful effect of ZOE on the composite. The aim of this in vitro study was to evaluate microleakage of composite restorations in pulpotomized primary molars with different bases for covering the ZOE layer and to assess the distance between different layers. MATERI...

OBJECTIVE The purpose of this study was to evaluate, by shear bond strength (SBS) testing, the influence of different types of temporary cements on the final cementation using conventional and self-etching resin-based luting cements. MATERIAL AND METHODS Forty human teeth divided in two halves were assigned to 8 groups (n=10): I and V (no temporary cementation); II and VI: Ca(OH)2-based cemen...

PURPOSE The purpose of this study was to repeat a 1997 survey of current pulp therapy practice. METHODS The directors of dental school predoctoral pediatric dentistry programs (N=56) and board certified pediatric dentists (N=1200) were surveyed in 2005. RESULTS More dental schools (83%) taught indirect pulp therapy (IPT) compared to 1997. Significantly more used glass ionomer for IPT with m...

OBJECTIVE Re-examining the well accepted concept that Zinc-Oxide-Eugenol bases (ZOE) have a negative effect on composite restoration materials microhardness, in light of the advancement in composite materials and newer publications. METHODS Five modern composite restoration materials were used, including hybrid (Xtra-fill and Z250), micro-fill hybrid (G-aenial and Gradia-direct) and methacryl...
