Light-Embrittled Dental Resin Cements Containing Photodegradable Polyrotaxane Cross-Linkers for Attenuating Debonding Strength [PDF]

ACS Applied Polymer Materials, 2020
Abstract Notwithstanding the progress of dental material adhesion on tooth surfaces in the past several decades, debonding strongly adhered restorative materials from tooth surfaces remains a challenging issue. Herein, we propose the use of photodegradable polyrotaxanes (PRXs), which are supramolecular-interlocked polymers comprising ...

Mechanical and Electrothermal Debonding: Effect on Ceramic Veneers and Dental Pulp

American Journal of Orthodontics and Dentofacial Orthopedics, 1997
This study compared the ability of three orthodontic debonding techniques for the removal of brackets from ceramic veneers without creating veneer damage. Three experimental groups included metal brackets debonded by either Howe pliers, lift off debonding instrument (LODI, 3M Unitek), or electrothermal debonder (ETD, "A" Company), as well as a group of

Effects of a flash-free system on dental plaque accumulation and bonding-debonding process: A clinical study

American Journal of Orthodontics and Dentofacial Orthopedics, 2023
The objectives of this study were to evaluate the effects of a flash-free (FF) System on (1) the amount of plaque accumulation around the braces on buccal surfaces of the teeth, (2) the time required for the placement of brackets, including the clean-up of the flash, (3) the amount of adhesive left on the tooth after debonding, and (4) time required ...

Comparative Study of Dental Enamel Loss After Debonding Braces by Analytical Scanning Electron Microscopy (SEM)

Microscopy Research and Technique, 2017
AbstractClinical procedures when shear forces are applied to brackets suggest adhesion forces between 2.8 and 10.0 MPa as appropriate. In this study dental enamel was evaluated by scanning electron microscopy (SEM) before and after removing the brackets.

Correlation between dental enamel chemical composition and bracket debonding, comparing adhesive systems through a scanning electron microscope

Microscopy Research and Technique, 2022
AbstractLiterature reports indicate that during bracket removal there can be enamel damage. We compare the shear bond strength (SBS) and tooth enamel loss of four adhesive systems and identify the Ca/P ratio. Then a total of 20 premolars were divided into four groups of five each.

Surface Treatment, Chemical Characterization, and Debonding Crack Initiation Strength for Veneering Dental Ceramics on Ni-Cr Alloys

Materials
Despite aesthetic trends, metal–ceramic restorations continue to be widely accepted due to their durability, and variations in surface preparation process can significantly influence bond strength outcomes. The purpose of this study was to determine whether there are differences in the bond strength depending on three surface treatment protocols for ...

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

Clinical Oral Investigations, 2013
The aim of this study was to undertake a qualitative and quantitative evaluation of changes on enamel surfaces after debonding of brackets followed by finishing procedures, using a high-resolution three-dimensional optical profiler and to investigate the accuracy of the technique.The labial surfaces of 36 extracted upper central incisors were examined.
