Summary

White spot lesions (WSL) are characterized by an apparently intact outer surface and a demineralized subsurface, and are considered the first clinical sign of dental caries. Aim of this study is to determine the treatment potential of self-assembling peptide (P11-4), casein phosphopeptide-amorphos calcium fluoride phosphate (CPP-ACFP) and resin infiltration technique to reverse or arrest the WSLs in the same oral environments in pediatric patients using visual assessments and laser fluorescence investigation.

Detailed description

White spot lesions (WSL) are characterized by an apparently intact outer surface and a demineralized subsurface, and are considered the first clinical sign of dental caries. These lesions are characterized by white chalky appearance. As caries is reversible under favorable conditions, many approaches have focused on treating it as soon as possible1. Aim of this study is to determine the treatment potential of self-assembling peptide (P11-4), casein phosphopeptide-amorphos calcium fluoride phosphate (CPP-ACFP) and resin infiltration technique to reverse or arrest the WSLs in the same oral environments in pediatric patients. This will be achieved using visual assessments and laser fluorescence investigation. The proposed study is a randomized controlled clinical trial with split-mouth design. Included are forty positive patients aged 9-17 years, with at least four visible WSL on smooth surfaces in permanent teeth, requiring non-operative treatment. WSL will be assessed visually by ICDAS II, Nyvad criteria and laser fluorescence (LF pen). The lesions are randomly assigned into 4 groups (n = 40): Gr NT (no treatment, control group), Gr CR (Curodont Repair), Gr V (MI Varnish), Gr I (Icon) groups. Lesions will be assessed by International Caries Detection and Assessment System, Nyvad caries activity criteria and laser fluorescence at baseline and follow-up period after1, 3, 6 and 12 months. Data will be analyzed with intention-to-treat concept by Student T-test for paired samples, Wilcoxon signed rank test, P\< .05. Pre-test on 20 subjects resulted in n=41 patients sample size.

Conditions

• White Spot Lesion of Tooth

Interventions

Type	Name	Description
DRUG	Self-assembling peptide (P11-4)	Prior to application, teeth are isolated by cotton rolls and gently air dried. The surface of the lesion is conditioned with a 2% sodium hypochlorite solution for 20 s and then rinse with water. Application of 35% phosphoric acid etching gel for 20 sec followed by rinsing with water-air spray for 30 sec. Drying the surface with compressed oil-free air for 60 sec. Curodont Repair is dissolve in 0.05 ml of distilled water and applied to the surface and allowed to work for about 5 min. Participants will receive oral hygiene instructions.
DRUG	CPP-ACFP	Prior to application, teeth are isolated by cotton rolls and gently air dried. Application of fluoride varnish with a brush applicator on the surface of the teeth for 5 minutes. Patients is advising not to brush their teeth or chew food for at least 4 h after treatment. Participants will receive oral hygiene instructions
DRUG	Resin infiltration	The validated ICON Vestibular (DMG) infiltration lesion infiltration protocol is applied. Icon Etch (DMG) etching gel containing 15% hydrochloric acid is applied for 120 seconds using an applicator. It is then removed by rinsing thoroughly with water-air spray for 30 seconds. Then follows application of pure alcohol - Icon Dry (DMG) for 30 seconds for complete drying of the lesion and additional drying compressed oil-free air for 40 sec. Application of Icon Infiltrant (DMG) using a microapplicator allows it to penetrate for 3 minutes, during which, if necessary, it is reapplied several times. Excess material is removed with dry microbrushes and followed by light curing for 40 seconds. Re-applying of the infiltrate for 1 minute, removal of excess material, light curing for 40 seconds. Participants will receive oral hygiene instructions
OTHER	Control Group, No Treatment	Everyday oral hygiene instructions Subjects will receive non-prescription fluoride toothpaste (1400 ppm Fluoride, Elmex junior) and oral hygiene instructions. The dosage will be 1/2 inch strip of paste 2x/day for 8 weeks. Subjects will apply paste to a toothbrush and brush teeth thoroughly for at least 1 minute then expectorate and rinse.
