In terms of composite resin restorations, nine studies concluded that it is "beneficial" [18,19,21,24,27,34,38,40,44], one described it as "probably beneficial" [35], and two concluded that this material had "no effect" [5,32]. Additionally, four studies evaluating indirect restorations and full coverage crowns concluded that this treatment is "beneficial" [16,39,45,46]; four studies assessing stainless steel crowns also concluded that this treatment is "beneficial" [15,17,36,43]; while two studies that evaluated microabrasion, whitening and infiltration of resin concluded as that these are "probably beneficial" [20,25].…”
