Clinical Evaluation of White Spot Lesions Treated by S-PRG Material and Composite Sealants in Comparison With ICON

Study Overview
=================
Brief Summary
-----------------
Dental caries is the primary cause of tooth loss and oral diseases. Dental decay is a continuous pathological process with loss of tooth minerals, demineralization, which involves the destruction of tooth structure from acids. The first sign of early active demineralization is white spot lesions (WSLs) on the tooth surface, meanwhile, subsurface active mineral decomposition.

Detailed Description
-----------------
Deposition of minerals depends on the equilibrium between demineralization and remineralization which may happen as a natural repair mechanism. The aim of this trial is to comparatively evaluate the efficacy of surface pre-reacted glass filler (S-PRG) Barrier Coat coating material against the Icon resin infiltration in the ability to improve the caries lesion state of the WSLs along 1 year. Laser fluorescence was used to compare the two materials to evaluate the caries progression. PRG Barrier Coat group showed immediate significant improvement in LF scores in demineralization progress and inhibition of caries progression with a significant improved effect. S-PRG Barrier Coat was clinically successful strategy in inhibition of caries and improve remineralization.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessments of caries lesion state of WSLs: | Assessing of carious lesions state of WSLs, was performed by using Diagnodent pen to record the progression or regression of caries by time. The assessment of the WSLs demineralization condition took place before intervention (baseline) [T0], immediately after intervention [T1], 3 months later [T2] ,6 months later [T3] and 1 year later [T4]. | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assessment of color change of WSLs: | The difference in color of the WSLs were performed by Vita Easyshade V at the five distinct times: before intervention (baseline) [T0], immediately after intervention [T1], 3 months later [T2] ,6 months later [T3] and 1 year later [T4]. | 1 year |
