Qualitative and quantitative evaluation of human dental enamel after bracket debonding: a noncontact three-dimensional optical profilometry analysis

Abstract

Morphological changes in the topography of dental surfaces, especially if related to enamel loss and roughness, are of considerable clinical importance. The quantitative evaluation method used herein enables a more comprehensive understanding of the effects of orthodontic bonding on teeth.

Enamel loss following ceramic bracket debonding: A quantitative analysis in vitro

“…Similar results have been reported for metal brackets after debonding and cleanup. 13,15,16 Both volume (product of area and depth) and mean depth were determined for ceramic brackets in this study, but depth is more clinically relatable. Since enamel thickness is in the range of 1500 to 2000 mm and a prophylaxis procedure using bristle brush or rubber cup causes enamel loss between 7 and 14 mm, 20 enamel loss of about 20-to 30 mm mean depth may be considered comparable with prophylaxis after dental cleaning.…”

“…[13][14][15][16] For metal brackets, adhesive remnants were reported after debonding as well as 20-to 50-mm enamel loss after removing the residual adhesive. 13,14 The aim of this study was to investigate two current-generation ceramic bracket systems and to quantify enamel surface changes after debonding.…”

A new method for the assessment of the surface topography of NiTi rotary instruments

“…, Ferreira et al . ). Recently, optical profilometry was also used to identify changes in physical properties of dentine surfaces after performing different endodontic regeneration protocols (Yassen et al .…”

Evaluation of shear strength of brackets with different dental composites and enamel roughness

“…Thus, the enamel roughness found after finishing is acceptable. Furthermore, residual adhesive could be removed with minimal damage to the enamel by the careful use of a tungsten carbide bur [47]. Considering the biochemical factors involved in dental caries development, higher concentrations of insoluble polysaccharides can cause a shift in demineralization [48].…”
