Bracket Bond Strength Effects Of Incorporation Of Novamin Into An Orthodontic Bonding Resin, Jeffrey Waterhouse
Bracket Bond Strength Effects Of Incorporation Of Novamin Into An Orthodontic Bonding Resin, Jeffrey Waterhouse
Master's Theses (2009 -)
Despite advances in caries research and the development of protective mechanisms and materials, orthodontic white spot decalcification remains a significant problem. Increased plaque buildup around orthodontic appliances, combined with inadequate hygiene and a susceptible patient, can lead to unesthetic demineralized lesions in enamel.
Relatively new to the arena of caries prevention, NovaMin, a bioactive glass, has shown some promise in areas of remineralization of early lesions, protection against acidic challenge, and has demonstrated antiplaque properties. This study explored a new application of the material, incorporation into an orthodontic bonding composite resin. Objectives of the study were: to determine if the …

The objective of this study was to compare the shear bond strengths (SBS) of orthodontic brackets bonded with self-etching primer using different enamel surface preparations.
A 2-by-2 factorial study design was used. Sixty human premolars were harvested, cleaned and randomly assigned to four groups (n=15/group). Teeth were bathed in saliva for 48 hours to form a pellicle. Treatments were assigned as follows: Group 1 was pumiced for 10 seconds and pre-etched for five seconds with 37% phosphoric acid before bonding with self-etching primer (Transbond Plus). Group 2 was pumiced for ten seconds before bonding. Group 3 was pre-etched for five …
