This study aimed to evaluate the effects of a new haemostatic agent (Ankaferd Blood Stopper, ABS) on the microtensile bond strength (mu TBS) of self-etch and etch and rinse adhesives to dentin. Flat dentin surfaces were divided into four groups per adhesive according to contamination procedures: group 1 (control): no contamination; group 2: blood; group 3: ABS; group 4: blood and ABS. Specimens were tested for mu TBS and data were analysed using analysis of variance and Tamhane tests. All groups showed lower mu TBS than the control group (p<0.05). The mu TBS in groups 3 and 4 was significantly higher than in group 2 (p<0.05). No statistically significant differences were observed in the mu TBS of the adhesives (p>0.05). The mu TBS of the ABS groups was lower than the mu TBS of the control groups but higher than the mu TBS of the blood contaminated groups. These results indicate that ABS application may be recommended after blood contamination during restorative procedures.
