ABSTRACT
PURPOSE:
During orthodontic treatment with fixed appliances, demineralization around brackets often occurs. The aim of this in vitro study was to investigate the effect of the caries-protective self-assembling peptide P114 (SAP P11-4) on the shear bond strength of metal brackets.METHODS:
In all, 45 extracted human wisdom teeth were available for the study. The teeth were randomly divided into 3 groups (each nâ¯= 15) and pretreated as follows test group 1 application of SAP P114 (Curodont Repair, Windisch, Switzerland) and storage for 24â¯h in artificial saliva; test group 2 application of SAP P114; control group no pretreatment with SAP P114. A conventional metal maxillary incisor bracket (Discovery, Dentaurum, Ispringen) was adhesively bonded to each buccal surface. The shear bond strength was tested according to DIN 13990. After shearing, the Adhesive Remnant Index (ARI) was determined microscopically (10â¯× magnification). Analysis of variance (ANOVA) was used to check the groups for significant differences (αâ¯= 0.05). The distribution of the ARI scores was determined with the χ 2 test.RESULTS:
There was no significant difference in shear forces between the groups (pâ¯= 0.121) test group 1â¯= 17.0⯱ 4.51â¯MPa, test group 2â¯= 14.01⯱ 2.51â¯MPa, control group 15.54⯱ 4.34â¯MPa. The distribution of the ARI scores between the groups did not vary (p-valuesâ¯= 0.052-0.819).CONCLUSION:
The application of the caries protective SAP P114 before bonding of brackets did not affect the shear bond strength. Therefore, pretreatment of the enamel surface with SAP P114 shortly before bracket insertion can be considered.Palavras-chave
