| Abstract | ||||
| Objectives: To assess remineralization of enamel white spot lesion by application of different materials with different application technique by measuring surface micro hardness and surface roughness Methods: A total number of 108 specimen obtain from 54 of sound freshly extracted human molar teeth were used in this study. The Specimens were randomly divided into three main groups according to type of varnish used with 36 specimens each, where (A1) demineralized enamel treated with Fluoride remineralizing varnish, (A2) demineralized enamel treated with CPP-ACP remineralizing varnish and (A3) demineralized enamel treated with TCP remineralizing varnish. Each treated group were further divided into four subgroups (B) according to the applied remineralizing paste with 9 specimen each, where (B0) represent no paste application, (B1) represent fluoride paste application, (B2) represent CPP-ACP paste application and (B3) represent TCP paste application Results: Microhardness recovery, where the highest recovery recorded by TCP Varnish with TCP Paste (95.26%) and the least recorded Fluoride varnish only (15.96%) .Where the highest mean surface roughness recorded by Fluoride Varnish and TCP Paste (0.2535±0.0004) and the lowest mean surface roughness recorded by Fluoride Varnish and Fluoride Paste (0.2513± 0.0011). Conclusions: 1. TCP varnish is the most effective among other tested varnishes in remineralization of early enamel caries. 2. The Combination of TCP and ACP-CPP paste with different tested varnishes enhance enamel remineralization compared to varnish only. Clinical significance: All application techniques of remineralizing agents can improve enamel surface roughness but not all can improve enamel surface micro hardness | ||||
