Abstract

PURPOSE:

This study compared fluoridated bonding resin adhesion to primary enamel (Group 1), primary dentin (Group 2), permanent enamel (Group 3), and permanent dentin (Group 4).

METHODS:

The buccal surfaces of 24 primary molars and 24 premolars were used. The bonding system and resin composite used in this study were Imperva Fluorobond and Lite-Fil IIA (Shofu Inc., Kyoto, Japan). Effects of tooth surface conditioning by FB primer were observed using SEM (N = 2/group). Shear bond strengths (SBS) were tested, and the test surfaces of enamel, dentin, and resin specimens were observed using SEM (N = 10/group). Data was statistically analyzed using one-way ANOVA with subsequent post hoc Duncan's new multiple range test at P < 0.05.

RESULTS:

Effects of tooth surface conditioning by FB primer were appropriate to dentin but low to enamel. Means and standard deviations of the SBS for each group were: Group 1 (16.34, 5.53 MPa), Group 2 (15.06, 7.02 MPa), Group 3 (14.39, 6.52 MPa) and Group 4 (15.45, 5.35 MPa). There was no significant difference of SBS among Groups 1, 2, 3, and 4.

CONCLUSION:

Imperva Fluorobond system gave the same level of bond strength to primary enamel, primary dentin, permanent enamel, and permanent dentin.
