PurposeFluoride-containing adhesives for enamel sealing are commonly used for the prevention of white spot lesions during fixed orthodontic treatment. Thus, we examined whether enamel sealing with L.E.D. ProSeal (R) (Reliance Orthodontic Products Inc., Itasca, IL, USA) before bracket bonding increases the rate of bond failure during orthodontic treatment.MethodsIn 20adolescents (11-16years, 10male/10female) at the start of fixed therapy, self-ligating SmartClipSL3 metal brackets (3M Unitek, Monovia, CA, USA) were bonded to cleaned and conditioned (40% H3PO4, 30s) buccal enamel surfaces of all permanent teeth except molars using Transbond XT (3M Unitek). In asplit-mouth design, either L.E.D. ProSeal (R) (1st/3rd quadrant) or Clinpro XT Varnish (2nd/4th quadrant; 3M Unitek) was applied to enamel surfaces before (ProSeal (R)) or after (Clinpro XT Varnish) bracket bonding (200 teeth each; light curing: 20s, Ortholux Luminous, 3M Unitek). Cumulative bond failure as total number of teeth with bracket detachment since start of therapy was documented every3months for atotal of 12months.ResultsCumulative bond failure was higher for enamel sealing before bonding from 6months onward reaching significance at 12months (34/200) compared to sealing after bonding (24/200): p=0.038; Cramer'sV =0.488; odds ratio (OR)=1.5; relative risk (RR)=1.4. The higher loss rate was limited to the lower arch, but evident within 3months reaching significance at9 and 12months (p=0.019/0.011, V=0.636/0.630; OR=1.7/1.75, RR=1.5/1.6). In general, cumulative bond failure at 12months was higher in the lower arch, but this was only significant for teeth sealed before bonding (p=0.001, V=0.303, OR=3.4, RR=2.8).ConclusionsEnamel sealing with L.E.D. ProSeal (R) should be performed after bracket bonding to prevent increased bond failure and bracket loss in the lower dental arch.
