Kanama durdurucu ajanlar n dental dokular n renk de i ikli i üzerindeki etkileri

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 ΔE*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.
