While it is reasonably well known that certain dental procedures increase the temperature of the tooth's surface, of greater interest is their potential damaging effect on the pulp and tooth-supporting tissues. Previous studies have investigated the responses of the pulp, periodontal ligament, and alveolar bone to thermal irritation and the temperature at(More)
PURPOSE This study was conducted to evaluate the effects of different phosphate monomer-containing primers on the shear bond strength between yttria-tetragonal zirconia polycrystal (Y-TZP) ceramics and MDP-containing self-adhesive resin cement. MATERIALS AND METHODS Y-TZP ceramic surfaces were ground flat with #600-grit SiC paper and divided into six(More)
BACKGROUND This study aimed to investigate the microshear bond strength of universal bonding adhesives to leucite-reinforced glass-ceramic. METHODS Leucite-reinforced glass-ceramic blocks were polished and etched with 9.5% hydrofluoric acid for 1 min. The specimens were assigned to one of four groups based on their surface conditioning (n = 16): 1) NC:(More)
OBJECTIVE The aim of this study was to evaluate the temperature change at various sites within the composite and on the pulpal side of dentin during polymerization of two composite increments. MATERIALS AND METHODS Class I cavities prepared in third molars were restored in two composite increments (n = 5). Temperatures were measured for 110 s using eight(More)
Biomaterials science is in the midst of the largest transition in its history in terms of refocusing and embracing new and exciting technologies. " For older academics or clinicians, this change might be viewed as the death of conventional dental materials, but for most others, this is the birth of true biomaterials " (1). Mineral trioxide aggregate (MTA)(More)
OBJECTIVE To evaluate the microshear bond strength (μSBS) of self-adhesive resin (SA) cement on leucite-reinforced glass-ceramic using silane or universal adhesive. MATERIALS AND METHODS Ceramic blocks were etched with 9.5% hydrofluoric acid and divided into three groups (n = 16): (1) negative control (NC) without treatment; (2) Single Bond Universal(More)
PURPOSE Salivary fluid formation is primarily driven by Ca(2+)-activated, apical efflux of chloride into the lumen of the salivary acinus. The anoctamin1 protein is an anion channel with properties resembling the endogenous calcium-activated chloride channels. In order to better understand the role of anoctamin proteins in salivary exocrine secretion, the(More)
Genetic information such as DNA sequences has been limited to fully explain mechanisms of gene regulation and disease process. Epigenetic mechanisms, which include DNA methylation, histone modification and non-coding RNAs, can regulate gene expression and affect progression of disease. Although studies focused on epigenetics are being actively investigated(More)
