Abstract:

BACKGROUND: Enamel demineralization happened easily in the process of orthodontic treatment. Fluoride application can inhibit the incidence of demineralization and promote enamel remineralization.
OBJECTIVE: To observe the effects of different concentrations of K2TiF6 on the adhesion property of dental enamel bonding resin.
METHODS: First premolars 80 teeth with orthodontic extraction from maxillary were randomly divided into five groups. Enamel with no K2TiF6 was as control group, and in the other four groups, enamel bonding resin containing 5%, 10%, 15%, 20% K2TiF6 was bonded edgewise brackets respectively.
RESULTS AND CONCLUSION: The result showed that shear bond strength and bond material adhesive remnant index of brackets in 20% K2TiF6 group were both decreased compared with the control group (P < 0.05), but there were no significant differences between the other three different concentration groups and the control group(P < 0.05). It suggests that when the K2TiF6 concentration in dental enamel bonding resin is no more than 15%, K2TiF6 does not affect the shear bond strength of brackets.
