Effects of Acidic Environments on Dental Structures After Bracket Debonding

open access: yesInternational Journal of Molecular Sciences, 2022
Brackets are metallic dental devices that are very often associated with acidic soft drinks such as cola and energy drinks. Acid erosion may affect the bonding between brackets and the enamel surface. The purpose of this study was to investigate the characteristics of brackets’ adhesion, in the presence of two different commercially available drinks ...

The Influence of Dental Loupes on the Quality of Adhesive Removal in Orthodontic Debonding [PDF]

open access: yesJournal of Orofacial Orthopedics, 2011
Bracket bonding has been a major advance in orthodontic treatment. However, the method of debonding can lead to diverse problems such as enamel fractures, enamel loss and enamel scratching. In this clinical investigation we aimed to evaluate the influence of wearing dental loupes on enamel damage during the debonding procedure.22 consecutive patients ...

Finite Element Analysis of Thermo-Debonding Mechanism in Dental Composites

Biomaterials, 2000
Finite element method (FEM) has been extensively used for evaluating interfacial status inside biomaterials. This study using FEM was designed to evaluate the thermal stress behavior of a filler-matrix interface. The results were then compared to those of a previous study obtained by a laser thermoacoustic technique (LTAT). The experimental systems (75/

Thermotransduction and Heat Stress in Dental Structures During Orthodontic Debonding

Journal of Orofacial Orthopedics, 2016
Recent studies have indicated possible thermal damage to pulpal tissue during orthodontic debonding. This study aimed to analyze the thermal loads acting upon dental structures and their transfer to the pulp during orthodontic debonding. Specific goals were to analyze temperature changes in local dental tissues, thermotransduction to the pulp cavity ...

Debonding Time and Dental Pulp Temperature With the Er, Cr: YSGG Laser for Debonding Feldespathic and Lithium Disilicate Veneers [PDF]

open access: yesJournal of Lasers in Medical Sciences, 2019
Introduction: The removal of ceramic veneers is a time-consuming procedure in a dental office. Little research has been done in alternative removal techniques for ceramic veneers. The objective of this study was to evaluate the removal of feldspathic and lithium disilicate reinforced glass ceramic veneers by Er, Cr: YSGG and to measure debonding time ...

Survival and Debonding Resistance of Posterior Cantilever Resin-Bonded Fixed Dental Prostheses for Moderately and Severely Worn Dentition During Thermomechanical Loading

Dental Materials, 2023
The purpose of this study was to investigate the survival rate, the debonding resistance, and the failure modes of different occlusal veneer designs when used as a retainer for posterior cantilever, resin-bonded fixed dental prostheses (RBFDPs) at two tooth wear levels.Four test groups were assigned: two groups with occlusal-proximal preparation (PT1 ...
