Professor and Head of the Department, Department of Public Health Dentistry, SRM dental college, Ramapuram, Chennai, India Abstract:- Flash-free adhesives, as an alternative to the process of Flash cleanup, which used to be a major part of conventional adhesive applications, apart from being an additive step, also tend to leave uneven clumps with the need for extreme technical expertise.To establish the status of Flash-free adhesives as an alternative to conventional adhesive systems for Orthodontic brackets. A literature search was performed using PubMed, Google scholar, Science direct, Lilacs and Grey literature using MeSH terms- Flash-free adhesives, Orthodontic brackets, fixed appliances. Out of 91 articles, 30 full-text articles were assessed for eligibility, and then four were taken for systematic review. This review was then reported according to the PRISMA guidelines. While compared to conventional adhesives, Flash-free adhesives are more effective in treating orthodontic brackets because of a reduction in the accumulation of plaque control and demineralization. The study concludes that it reduces the extent of accumulation of plaque control by eliminating excess adhesive and reducing bracket failures. The use of flash- free adhesives is more effective in the treatment of orthodontic brackets. Keywords:- Flash-free adhesives, Orthodontic Brackets, Conventional adhesives, Flashcleanup. I. INTRODUCTION Successful orthodontic treatment ensures the patient's comfort throughout theduration of the treatment. As Kirk A Davis highlights the importance of chair time, being the King in orthodontics, he mentions how with the significant reduction of chair time, they were able to complete more cases and remove the painstakingly long bonding appointments from their schedule [1]. Application of orthodontic brackets forms a core part of most of its treatment territory [2]. An ideal procedure for the application of an orthodontic bracket involves the safety of providing minimal damage to the surface during debonding [3]. Thus, judging on the given scenario, it posed a challenge to how this specific process could be made simpler, paving the way to the world of flash free adhesives. As Kirk A Davis mentions, free adhesives show how exhausting flash removal is in the bonding process, highlighting its dependence on fine motor skills, constant concentration and visual focus[1]. Flash-free brackets significantly reduce the application time and provide notable retention, protecting the enamel from demineralisation during treatment. Apart from the time factor, flash-based adhesives also show a high preference for white spot lesion formations. Greek et al. found that WSL occurred at least once post- fixed orthodontic treatment[4]. Other studies range an incidence range of around 2-96% [5,6]. The cause has been identified as the persistence of excess adhesive flash, which acts as gingival irritation, thus amplifying the chances [7] of bacterial colonisation, thus contributing to the increased incidence[8,9]. Conventionally, flash, the excessive adhesive that flows around the base of the bracket, forms a hotspot for plaque accumulation contributed by enamel demineralisation, making oral hygiene practices for the patient troublesome. When flash free adhesives placed on the tooth it decompresses at the base of the bracket[10]. When orthodontic treatment is completed, the removal of the attachments, as well as the residual adhesive, produces clouds of visible dust, aerosols formed by agglomeration or a chemical reaction of vapours, classified by the mass median aerodynamic diameter (MMAD) produced, which splatters into the air surrounding the patient as well as the operator[11]. When discussing bond failure, bond strength comes to play, and among the articles testing it, 3 of them show high bond strength using flash-free adhesives[12,13.14]. However, one must remove this adhesive from the tooth surface, which takes up the maximum chunk of time for both the clinician and the patient during an appointment. A significant reduction of time in the flash removal process was seen in three studies. [15,16]. The result of a flash-free adhesive is equal, whenattached at the final step of cleaning
