In vitro lingual bracket evaluation of indirect bonding with plasma arc, LED and halogen light Orthod Craniofac Res 2010; 13 :48–55 Structured Abstract Authors – Magno AFF, Martins RP, Vaz LG, Martins LP Objectives – Evaluate the shear bond strength (SBS) and the adhesive remnant index (ARI) of indirect bonded lingual brackets using xenon plasma arc light, light‐emitting diode (LED) and conventional quartz‐tungsten‐halogen light. Material and Methods – Lingual brackets were bonded indirectly to 60 premolars divided to three groups according to the curing light used: Group 1, plasma arc for 6 s; Group 2, LED for 10 s; and Group 3, halogen light for 40 s. After bonding, the specimens were subjected to a shear force until debonding. The debonding pattern was assessed and classified according to the ARI scores. The mean shear bond strengths were accessed by anova followed by the Student‐Newman‐Keuls test for multiple comparisons. ARI scores were assessed using the chi‐square test. Results – The three groups showed significant differences ( p < 0.001), with the averages of group 1 < group 2 < group 3. Groups showed no differences regarding ARI scores. Conclusion – Bonding lingual brackets indirectly with plasma arc, during 60% of the time used for the LED, produced lower SBS than obtained with the latter. Using LED during 25% of the time of the halogen light produced lower SBS than obtained with the latter. These differences did not influence the debonding pattern and are clinically acceptable according to the literature.
