Abstract
Context: Despite the advances in orthodontic material and treatment mechanics, the placement
of fixed appliances increases the risk of enamel demineralization. The development of fluoride
release adhesives has attracted considerable interests because the combined use of antimicrobials
and fluoride enhances the cariostatic effect.
Aim: To compare the shear bond strength (SBS) of fluoride release adhesives with established
orthodontic adhesives and assess failure mode using adhesive remnant index (ARI).
Settings and Design: The present study included 80 maxillary premolars which were randomly
divided into four groups (n = 20) and were further subdivided into two subgroups A ‑ Pumice
prophylaxis (PP) and subgroup B ‑ No PP (n = 10).
Materials and Methods: Stainless steel brackets were bonded with Transbond XT, Transbond
plus (TP) color change adhesive, Light Bond, and Clearfil protect bond. After debonding, the
ARI was used to assess the mode of bracket failure.
Statistical Analysis: The data were analyzed using two‑way analysis of variance, Post‑hoc Tukey
Honest significant differences test, and Chi‑square test.
Results: The mean SBS of Group 4 was comparably higher regardless of PP. Brackets bonded
with TP showed a comparable SBS to conventional Transbond XT. The ARI scores were
predominately 2.
Conclusions: 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.
