Fluorescence‐aided composite removal during lingual bracket debonding

Abstract

Objective: This report describes the fluorescence-aided composite removal during lingual bracket debonding with an ultraviolet light emitting diode flashlight. The purpose of this technique is to help clinicians in composite removal without enamel surface damage. Clinical considerations: The bracket debonding requires clinical attention in order to remove all composites and resins without enamel surface damage. Different protocols can be used in order to minimize the enamel damages and the excess bonding remnants. The fluorescence-aided composite removal permits to have an immediate visualization of the composites and adhesives, especially for the uneven lingual surfaces, of which the interindividual morphological variability is greater than the buccal surfaces. Conclusions: The fluorescence-aided composite removal during lingual brackets debonding minimizes the risks described in literature and it is an easier, more accurate, reliable, noninvasive, inexpensive, and time-saving method. Clinical significance: The application of this technique allows, with inexpensive flashlights, to remove all the composite on the lingual surfaces during debonding, without damaging the tooth and saving time.

Fluorescence-aided removal of orthodontic composites: an in vivo comparative study

“…FIT can simplify the orthodontic debonding procedures [ 13 , 15 – 17 , 25 ]. It is even more effective during the lingual brackets debonding, when distinguishing enamel and resins is even more complex for the less accessibility and for the greater interindividual morphological variability of lingual surfaces [ 16 , 26 ].…”

“…This study describes the fluorescence-aided adhesive removal with an ultraviolet (UV; 395 nm wavelength) light-emitting diode (LED) Veetop (Indialantic, Florida) flashlight, already used in a previous article [ 16 ].…”

“…Furthermore, several studies have reported that auxiliary devices are useful for removal of fluorescent residue after bracket debonding, allowing the selective removal of adhesive and preserving the dental tissue [ 13 – 15 ]. Thus, fluorescence-aided composite removal can be used in orthodontics not only during lingual and buccal bracket debonding, but also during the removal of attachments in clear aligner therapy [ 16 , 17 ].…”

Efficacy of Bracket Adhesive Remnant Removal by a Fluorescence-Aided Identification Technique with a UV Light Handpiece: In Vitro Study

“…e fluorescence-aided identification technique (FIT) has been developed to facilitate the visualization of differences in fluorescence levels between the tooth structure and the dental material [14][15][16][17]. Recently, the method was adapted for the recognition of orthodontic adhesives [18][19][20][21][22]. Fluorescence is defined as the property of absorbing short wavelength light and emitting longer wavelength light, which can or cannot be seen [23].…”

“…is phenomenon occurs in natural teeth [24,25], and for sound enamel, the range of light emission is 430-450 nm, which is usually in a different color or intensity from dental material, making it possible to distinguish the fluorescence emission of the tooth structure from the material [16,26]. erefore, when fluorescent emission is used to detect adhesive remnants, it is desired that the bracket adhesive shows a fluorescent level higher than the intact tooth [13,[18][19][20][21][22][27][28][29]. In this way, some manufacturers developed special bracket adhesive materials with high fluorescence levels to facilitate their detection using FIT.…”
