Abstract
This study investigated the physicochemical and mechanical properties of a 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP)-based self-adhesive luting cement (Smart Ortho) in comparison with a conventional orthodontic bonding system (Transbond XT). The evaluation focused on polymerization behavior, mechanical performance, and thermal stability. Depth of cure, degree of conversion, flexural strength, shear bond strength, adhesive remnant index, and thermogravimetric analysis were assessed. Metal and ceramic brackets were bonded to bovine enamel under different surface treatment conditions, with or without primer application and with or without thermocycling. Statistical analyses were performed at a significance level of α = 0.05. No significant differences were found between the two materials for depth of cure, degree of conversion, flexural strength, shear bond strength, or adhesive remnant index (P > 0.05). Thermogravimetric characterization revealed similar thermal degradation profiles for both materials. A higher residual mass was observed for Transbond XT (74.89%) than for Smart Ortho (48.20%), suggesting a greater proportion of inorganic filler in the former material. Despite this, Smart Ortho demonstrated equivalent polymerization efficiency, mechanical resistance, and adhesive performance. The inclusion of 10-MDP likely contributed to stable chemical interaction with enamel, even in the absence of primer. These findings highlight the potential of Smart Ortho as a simplified alternative for orthodontic bonding procedures. Further long-term studies under clinical conditions are recommended to confirm its performance.
•10-MDP cement showed performance comparable to Transbond XT.•No differences in conversion, strength, or depth of cure.•Thermocycling (20,000 cycles) did not affect bond strength.•Primer use did not influence Smart Ortho bond performance.•Transbond XT showed higher inorganic filler content.
