Comparison of the enamel surface roughness before bonding and after debonding by diamond, tungsten carbide and fiber reinforced composite burs under AFM an in-vitro study
Journal Title: IP Indian Journal of Orthodontics and Dentofacial Research - Year 2018, Vol 4, Issue 3
Abstract
Introduction The bonding of orthodontic attachments directly to etched enamel surface is an example of clinical application of a simplified procedure With modifications of the acid etch technique and resin systems the removal of the directly bonded attachments and finishing of the underlying enamel have become an acute clinical problemAims and Objectives To evaluate the enamel surface roughness observed under atomic force microscope AFM in following methods 1 Before bonding 2 Removal of residual resin after debonding with 3 different burs Fine diamond bur Tungsten carbide bur Fiber reinforced composite burMaterials and Methods Sixty premolar teeth were divided into 3 equal groups and the buccal surface were subjected to AFM to obtain Ra Rq Rmax initial roughness values The brackets were bonded with a lightcured adhesive and debonded with posterior debonding plier Residual resin was removed with different burs in 3 groups respectively and subjected to final AFM measurements Results of roughness were analysed with the use of repeated measurement analysis of variance and independent ttest respectivelyResults It was found out that parametric values were statistically insignificant with P value 0001 in prebond condition statistically significant after resin removal with P value 0Conclusion Fiber reinforced composite bur created smoother surface after debonding when compared to diamond and tungsten carbide burKeyword Fine diamond bur Tungsten carbide bur Fiber reinforced composite bur Residual resin AFM
