Comparison of Gluma bond strength to primary vs. permanent teeth
1Department of Pediatric Dentistry, Medical College of Georgia, Augusta.
Abstract:
The purpose of this study was to measure the shear bond strength of Gluma/Lumifor (Gluma and Lumifor--Columbus Dental, St. Louis, MO) to the occlusal dentin of primary first and second molars, permanent first and second molars and premolars. The data were examined for differences using a one-way analysis of variance and Duncan's Multiple Range test. The shear bond strength, (kc/cm2, x +/- SEM) to primary molars was 85.6 +/- 13.7, to permanent molars was 110.1 +/- 9.3, and to premolars was 124.0 +/- 9.3. Gluma/Lumifor provides moderately good bonding to dentin. The bond strengths of Gluma/Lumifor to primary molars was statistically significantly lower than to permanent teeth.

Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons from...
