Effects of different pretreatment agents on primary tooth dentin bonding durability
Objective To explore the effects of different pretreatment agents on primary tooth dentin bonding durability. Methods Forty-two retained primary molars were selected, 24 of which were cut along the mesial and distal directions; thus, 48 samples were obtained for shear bond strength tests, and the ot...

| description | Objective To explore the effects of different pretreatment agents on primary tooth dentin bonding durability. Methods Forty-two retained primary molars were selected, 24 of which were cut along the mesial and distal directions; thus, 48 samples were obtained for shear bond strength tests, and the other 18 teeth were used for nanoleakage tests. According to different pretreatments, both experimental samples were divided randomly into three groups (Group A: distilled water pretreatment group; Group B: 2% chlorhexidine pretreatment group; Group C: 10 mg/mL resveratrol pretreatment group). The test specimens were prepared, the shear bond strength was tested, and interfacial nanoleakage evaluation and scanning electron microscope observation were performed to evaluate the effects of different pretreatment agents on the bonding interface immediately and after aging for one hour with 10% sodium hypochlorite aqueous solution. Results The immediate shear bond strength results showed that there was no significant difference among the three test groups. After aging, the shear bond strength of Group C was significantly higher than that of Group A and Group B (P<0.05). After aging, the shear bond strength of Group A was significantly lower than the immediate shear bond strength (P<0.05), whereas there was no significant difference in shear bond strength before and after aging in Group B and Group C (P>0.05). For Group C, there was no significant difference in interfacial nanoleakage before and after aging. In addition, among the three groups, Group C had the lowest interfacial nanoleakage (P<0.05). Conclusion Both chlorhexidine and resveratrol pretreatment can improve the adhesion durability of deciduous dentin, but the effects of resveratrol are better than those of chlorhexidine. |
