Remineralization Potential of Pearl Powder Compared to CPP-ACP on Enamel White Spot Lesions

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to evaluate the remineralization potential of pearl powder on early ('white spot') lesions in enamel in orthodontic patients compared to casein phosphopeptide-amorphous calcium phosphate.

Detailed Description
-----------------
The aim of this study is to evaluate the remineralization potential of pearl powder on early ('white spot') lesions in enamel in orthodontic patients compared to casein phosphopeptide-amorphous calcium phosphate. The remineralisation potential will be assessed both visually and by standardised photographic image analysis. the follow up will be up to 12 months.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Cpp-acp<br>MI paste Self-administration of the product by the patient once in the evening. A pea-size amount of the product should be applied per arch, using a dry finger or cotton pellet to distribute it evenly across all teeth and to work it into the interdental spaces. The product was then retained in the mouth for 1-3 min, and manipulated around the teeth using the tongue, before being expectorated and patient should not rinse it until 30 min. | Drug: Cpp-Acp<br>* Remineralising agent<br>* Other names: MI paste;|
| Experimental: Pearl powder<br>Pure pearl powder in the form of gel Self-administration of the product should be used once daily (in the evening), after a 2 min manual tooth brushing. .Participants were explicitly instructed to apply the gel by his finger allover the teeth and not to rinse their mouths after application and not to eat or drink for at least 30 min. | Other: Pearl powder<br>* Natural product<br>|
