Background and Aim: Effective composite bonding to primary teeth is crucial. Cold plasma treatment could enhance this bonding. This study investigated the effect of cold atmospheric plasma on dentin microshear bond strength (µSBS) of primary anterior teeth.
Materials and Methods: In this in vitro study, 84 eligible primary anterior teeth were randomly assigned to six groups: (I) Adper Single Bond 2 fifth-generation bonding agent, (II) fifth-generation bonding agent + 15-second plasma treatment, (III) fifth-generation bonding agent + 30-second plasma treatment, (IV) Single Bond Universal adhesive, (V) universal adhesive + 15-second plasma treatment, and (VI) universal adhesive + 30-second plasma treatment. The µSBS test was then performed. Fracture mode was determined under a stereomicroscope. Scanning electron microscopy (SEM) and stereomicroscopic assessments were also performed. Data were analyzed by one-way and two-way ANOVA, and Tukey and t tests.
Results: The universal adhesive group had a significantly higher µSBS (39 MPa) than the fifth-generation bonding group (13.5 MPa). A significant difference existed between the no plasma and 30-second plasma treatment groups (P=0.001). In the universal groups, significant differences were noted between no plasma and both 15-second and 30-second treatments (P<0.05). Universal adhesive outperformed the fifth-generation bonding agent in the no plasma and 15-second treatment groups (P=0.007). Adhesive failures predominated in all groups, and SEM analysis showed distinct differences in dentinal tubules among the bonding systems.
Conclusion: It is recommended to use Single Bond Universal adhesive without plasma, and consider plasma treatment to enhance bonding in Adper Single Bond 2 fifth-generation system.
