| Abstract |
| The aim of this study is to evaluate the effect of three treatment modalities for white spot enamel lesion namely; resin infiltration, remineralization and micro-abrasion on enamel surface roughness and micro-hardness. Artificial white spot lesions were produced in enamel surface from a sixty intact extracted human permanent premolars were selected for the study. The selected teeth were divided into two groups according to variables to be tested (30 teeth for each group); surface roughness measuring and micro-hardness measuring. Each group was further sub-divided into three subgroups according to methods of treatment of white spot lesion (10 teeth each); resin infiltration, micro-abrasion and remineralization. For both surface roughness and micro-hardness, the assessment was done three times; prior to WSLs productions (baseline) after WSLs production (pretreatment phase) and after treatment (post treatment phase). Data base line and post treatment phase for each parameter will be recorded and tabulated. Statistical analysis was done using one way Anova . The results of the current study showed that after treatment of WSLs the surface roughness improved significantly in all tested groups but there was no statistically significant difference between all treated groups. Also, the results of the current study showed that after treatment of the WSLs the microhardness increased in all groups . The three tested modalities for the treatment of white spot lesions could improve the surface roughness and the micro-hardness of the treated enamel but the Opalustre® and Tooth Mousse™ were equally effective in improving the microhardness® and more effective than Icon. |
