Abstract
Aim: To measure the bad effects of different root canal irrigating solutions on bulk-fill composite bonding to coronal tooth structure by Micro-tensile bond strength evaluation.
Method: 15 human permanent lower molars were selected for the present study. To standardize, every tooth has decoronated to 4 mm coronal to cementoenamel junction using diamond disc bur for standardization, and making sure that the hight of the pulp chambers wall is 3mm from pulp chamber floor. All teeth prepared by ProTaper rotary instruments up to size F3, ProTaper obturators #F3 were used to fill the root canals and resin sealer (ADSEAL) were used for filling the canals via the lateral condensation method. 2 mm apically of the coronal gutta percha was removed to make a space for liner material. Glass ionomer restorative was used as liner material over the gutta percha to the level pulp chamber floor. The obturated teeth were then randomized divided into three identical test groups Group A (Sodium hypochlorite), Group B (Chlorhexidinle), and Group C (EDTA) of 5 molars each in accordance with the final irrigation solution used in the pulp chamber. Each test group was received 1ml from the tested irrigation solution according to the groups for 1minute and received ultra sonic irrigation for 20 seconds. These steps were repeated 4 times to reach 5 minutes final. then pulp chamber walls irrigated by saline for 1 minutes. The dentin surface was coated with a self-etch adhesive technique. A 3mm Single layer of composite resin 3M™ Filtek™ One Bulk Fill Restorative were bonded on the treated dentin surfaces. Micro-tensile bond strength test was used to measure the bond strength of bulk-fill composite bonding to coronal tooth structures.
Results: The highest mean value of micro tensile bond strength was recorded in group B (Chlorhexidine) 19.80 ± 1.42 with statistically significant difference (P value = 0.015) in comparing with the other two test groups, the group A (Sodium hypochlorite) recorded 14.38 ± 0.91, while group C (EDTA) recorded the lowest values of micro tensile bond strength 12.95 ± 1.38.
Conclusion: Chlorhexidine has less hazards effects on Micro-tensile bond strength of composite bond to coronal dentine when comparing to Sodium hypochlorite and EDTA.
