Comparative evaluation of effect of different polishing systems on surface roughness of composite resin: An in vitro study

Abstract

Aims and Objectives:Satisfactory composite restoration depends upon its smooth finish, quality of polishing agents, type of composite material used, and its composition. The present study evaluated the effect of different polishing systems on the surface roughness of composite resin.Materials and Methods:Forty discs of composite were prepared and equally subjected to different finishing and polishing procedures; (i) unpolished control group, (ii) sof-lex discs, (iii) diamond tips, and (iv) Astrobrush groups. Later, the surface roughness for the entire specimen was evaluated using Profilomotor. Data were tabulated and statistically analyzed using analysis of variance and Tukey's test at significance level of 0.001.Results:Composite surface roughness after polishing was statistically significant between the groups. Sof-lex group produced lesser surface roughness compared to control, Astrobrush, and diamond group.Conclusion:The present study indicated that diamond tips can be used to remove rough surface whereas sof-lex can be used for final finish and polish of the composite restoration.

Aesthetic Rehabilitation of Enamel Hypomineralization with Microabrasion and Direct Composites (18 Month-Follow-up Report)

“…The resin used in this case has supra-nano-size inorganic fillers, that give high mechanical resistance, low polymerization shrinkage value, good polishing and optical properties to the material (24)(25)(26). Polishing is a clinical key step to maintain color stability as well as the surface roughness of the restoration (27)(28)(29). Interdental polishing and surface polishing of the restorations were done with recently developed diamond embeded interdental strips and spiral rubber discs in the case presented.…”

Emprego De Restaurações Indiretas Em Cerâmica Para Mascaramento De Substrato Dentário Escurecido: Caso Clínico

“…etapa de procedimento origina ainda muita controvérsia, em relação ao momento da sua realização, se será feita de imediato logo ao término da restauração ou após o período de uma semana, devido a deformação plástica dos compósitos (YADAV et al, 2016). O polimento nesse caso foi realizado imediatamente ao término da restauração, apesar de muitos profissionais pregarem a sua realização apenas na sessão seguinte, para evitar manchamento injúrias ao material restaurador, há estudos que provam o efeito inverso do polimento imediato (CHOUR et al, 2016;LINS et al, 2016). Lins et al (2016), demonstrou que a taxa de microinfiltração nas resinas com o polimento realizado de forma imediata é bem inferior.…”

Minimally invasive aesthetic rehabilitation in composite resin: report of two clinical cases

“…In this context, the finishing and polishing techniques used are important steps to enhance both the esthetics and longevity [2,22]. According to Chour et al, diamond polishing paste can be used to remove rough surface whereas sof-lex for final finish and polish of the composite restoration, increasing longevity of restorations [23].…”

“…The existing restorations were removed with a spherical diamond bur #1014 (KG Sorensen, Barueri, Brazil), used under constant water irrigation (Figure 6b). Then, adequate isolation was performed using a rubber dam isolation modificated (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) (Figure 6c). After the teeth preparation, the same adhesive protocol and materials applied in case 1 were performed.…”
