    The effects of hemostatic agents to color change of dental tissue
    (2012) Yalçin M.; Karaarslan E.Ş.; Umar I.; Cebe M.A.
    Objectives: The aim of this study was to investigate the effects of hemostatic agents to the color change of dental tissues. Materials and Methods: 40 extracted human third molars which are not affected by caries used in this study. Occlusal surfaces removed to obtain flat dentinal surfaces and teeth mounted acrylic. Specimens were divided into four groups of 10 to be tested four different hemostatic agents. Prepared tooth groups were aplied hemostatik agent (Hemoban, Sultan®, USA; Hemospad, Dentsply, Germany; Ankafert Blood Stopper©, Ankafert, Turkey; Hemostatic solution, WP dental, Germany). Before and after application of hemostatic agents to flat surface of teeth, L*a*b* values were measured with a colorimeter (Easyshade® Compact, VITA, Germany), and ?E*ab values were calculated. Data were compared using Kruskall-Wallis H ve Mann-Whitney U tests (p=0.05). Results: The highest color change were found with Hemoban hemostatic solution. The lowest color change was observed with Hemospad hemostatic agent (p<0.05). There were statistically significant differences amoung groups according to color change (p<0.05). Conclusions: As a result, hemostatic agents used in dentistry as a hemostatic can cause color change over the dentine tissue. Therefore, when solutions which are used as a hemostatic agent are used, should be careful to avoid contact these solutions with the open dentine tissue.

    Influence of caries detection dye on composites bond strength of carious affected dentin
    (Cumhuriyet University Faculty of Dentistry, 2014) Yalçin M.; Cebe F.; Cebe M.A.; Dündar A.; Öztürk B.; Şengun A.
    Objectives: The aim of this in vitro study was to evaluate effect of three different caries detecting dyes on shear bond strength of a self etch adhesive to caries affected dentin. Materials and Methods: 60 extracted human third molars which are affected by caries used in this study. Occlusal surfaces removed to obtain flat dentinal surfaces and teeth mounted acrylic. Specimens were divided into four groups of 15 to be tested three different caries detecting dyes. First group is control and others Caries Detector, Quadrant Cari Test, Sable Seek groups. In control group decayed dentine tissues remowed with silicon carbite papers (300 gride) and in others groups caries detectors applied and carious dentine tissues remowed with silicon carbite papers. Than dentin bonding systems Clearfil SE Bond applied and specimens restorated with composite resin. All products were used according to manufacturer's instructions. Bond strengths were tested and data were statistically analyzed one-way Analysis of Variance (ANOVA) and Tukey tests. Results: As results of this study, Quadrant Cari Test group showed lower bond strength than other detecting dyes groups. While bond strengths of Caries Detector and Sable Seek groups were similar, their bond strengths were significantly higher than Quadrant Cari Test group (p<0,05). Conclusions: According to the results of this in vitro study caries detecting dyes may lead to increased shear bond strength values obtained.
