Surface roughness and microhardness of enamel white spot lesions treated with different treatment methods

ObjectiveTo analyse the surface roughness and microhardness of artificial enamel white spot lesions before after WSL formation, treatment (Opalsutre™ microabrasion, Sylc® bioactive glass, ICON® resin infiltration), pH cycling with help profilometer tester digital Vickers tester.Materials methodsSeventy-five extracted molars were used to acquire one hundred specimens. 50 specimens randomly assigned five groups (n = 10) for study: 1) Sound group, 2) 3) micro abrasion (MA; Opalustre, Ultradent, South Jordan, UT, USA), 4) glass 45S5 Sylc powder (Sylc; Denfotex Research Ltd, Inverkeithing, UK), 5) ICON infiltration (ICON; DMG, Hamburg, Germany). An additional 25 obtain slabs study, which also same groups. All underwent a final stage cycling. Surface measurements performed at different stages all groups.ResultsRegarding roughness, significantly reduced compared Opalustre Sylc, no significant difference between Sylc. In terms microhardness, showed highest improvement, followed by then Opalustre. Both affected demineralization, partially improved treatment, regressed cycling.ConclusionICON infiltrant can be considered as superior option improving while demonstrated relatively poorest performance other options. It is noteworthy that procedure had an adverse impact irrespective used.
