Comparison of shear bond strength of self-etching fluoride releasing adhesives with and without pumice prophylaxis

Abstract

Fluoride releasing adhesives combined with antibacterial monomer can play a vital role in reducing white spot lesions by enhancing the cariostatic effect especially in noncompliant\medically compromised patients.

Evaluation of the Effects of Topical Fluoride Varnish and Fluoride Releasing Adhesive on Shear Bond Strength of Orthodontic Brackets: An In Vitro Study

“…Available literature reports 2.86–7.59 MPa as an ideal bond strength necessary to resist orthodontic force. 9 All bonding materials, when evaluated in our study, presented SBS values ranging from 9.48 to 12.3 MPa. The results of ANOVA showed a statistically insignificant difference between groups I, II, and III ( p = 0.091).…”

“… 4 – 6 Therefore, preventive measures independent of patient compliance have been developed; these include bonding materials having fluoride-releasing properties that discharge additional fluoride near the brackets. 7 , 8 These materials follow a typical pattern of fluoride release, with the largest amount of fluoride being released within the first few days of application, followed by a quick decline to lower levels due to the small amount of incorporated fluoride—a phenomenon called “burst effect.“ 9 …”

“… 10 , 11 These have become popular because of their ease to use and the lack of dependence on patient cooperation. 9 It has been observed that fluoride varnishes decrease enamel demineralization around brackets, but the requirement of their reapplication during the treatment results in high cost and increased clinical chair time. 12 – 15 …”
