Gluma bond strength to the dentin of primary molars.
The purposes of this study were to measure and compare etching patterns, tensile bond strengths and fracture patterns of Gluma/Lumifor system to the buccal dentin of primary molars following application of Gluma cleanser and 37% phosphoric acid. The tensile bond strength of Gluma/Lumifor to the buccal dentin following application of Gluma cleanser averaged 5.53 +/- 3.27 (x +/- SD MPa) which is significantly greater than bond strength following application of only 37% phosphoric acid 2.04 +/- 0.67. Etching ground buccal dentin surfaces with 37% phosphoric acid has no significant different effect on the bond strength of Gluma/Lumifor combination. Gluma cleanser showed effective removal of the smear layer and partial plugging of the dentinal tubules, while 37% phosphoric acid showed complete removal of the smear layer creating opened dentinal tubules.
