To evaluate the remineralization potential of PRG Barrier Coat versus fluoride varnish in white spot lesions in permanent anterior teeth of children.
Children aged 8-14 years with good health according to the American Society of Anesthesiologists (ASA-I).
Have at least one white spot lesion with International Caries Detection and Assessment System (ICDAS II) score one or two
Has not used any remineralizing agent in the former three months.
Parents who accept to sign informed consent.
Patients have caries or restorations in the labial surface.
Extrinsic or intrinsic stains.
patients under active orthodontic treatment.
Uncooperative patient.
Parallel
5% NaF fluoride varnish
Other interventionBefore the application of the varnish, teeth were cleaned using a prophylaxis polishing past with a low-speed cone brush in a contra angle low-speed handpiece. It will be dried with air and isolated using cotton rolls. Package will be unpacked, and the application guide will be used to display the contents and mix to avoid the separation of sodium fluoride components. After isolation, a thin layer of the varnish will coat . The participants will be asked to keep their mouths closed to allow the varnish to set in the presence of saliva. Rinsing or suction was not allowed immediately after the application of the varnish. The participants will be asked to avoid consumption of rough and viscid food or hot drinks for two hours after application of the varnish. For the rest of that day, participants will be asked to eat soft food and stop tooth brushing (Ezzeldin et al., 2024).
PRG Barrier coat
Other interventionBefore the application of the varnish, teeth were cleaned using a prophylaxis polishing past with a low-speed cone brush in a contra angle low-speed handpiece. It was then dried with air and isolated using cotton rolls. \| P a g e 13 According to the manufacturer's instructions, the application of PRG barrier coat varnish a drop of the active will be mixed with the base using the attached brush. After isolation with cotton rolls, the brush will be used to smear the WSLs with the mix. I will be undisturbed for at least three seconds, then cured for 10 seconds using the visible-light curing unit (Ezzeldin etal.,2024). And there will be no post operative instruction to patient after application (light cured resin material).
Remineralization potential ΔE: will be recorded by the differences in color perception by Spectrophotometer
The name of measurement: CIELAB parameters, which will record the difference in color perception. The CIELAB, or CIE L\* a\* b\*, color system represents quantitative relationship of colors on three axes. The measurement tool: spectrophotometer. (L\*a\*b\* values) L\*: denoted the tooth lightness. 1. : indicated hues change across the red-green axis. 2. : represents hues difference across the yellow-blue axis.
ΔE 2000 will be recorded by Spectrophotometer
ΔE 2000 will evaluate color difference. kL, kC, and kH are parametric coefficients that allow users to adjust the weighting of lightness, chroma, and hue differences, respectively. kL: This coefficient controls the weighting of the lightness difference (ΔL\*) component in the color difference calculation. kC: This coefficient controls the weighting of the chroma difference (ΔC\*) component. kH: This coefficient controls the weighting of the hue difference (ΔH\*) component.
