Effectiveness of Different Remineralizing Strategies on the Management of Early Carious Lesions in Primary Teeth

Early Phase 1

Completed

• Conditions: White Spot Lesion
• Interventions: Drug: Casein phosphopeptide amorphous calcium phosphate; Drug: 5% sodium fluoride varnish; Drug: self assmbling peptide p11-4 combined with 0.05% fluoride

• Registration Number: NCT06566833
• Lead Sponsor: Alexandria University

Brief Summary

the primary aim of the study is remineralization of early carious lesions in primary teeth using different remineralizing agents of different remineralizing strategies when applied in an intensive mode. The secondary aim of the study is to compare their antibacterial effect against streptococcus mutans and their effect on reducing the size of the lesions.

Detailed Description

The primary aim of the study is to compare the effect of curodont repair fluoride plus (self-assembling peptide p11-4 with 0.5% sodium fluoride) with MI varnish (casein phosphopeptide amorphous calcium phosphate fluoride) and Colgate fluoride varnish (5% sodium fluoride) in remineralization of early carious lesions in primary anterior teeth. The study sample is consisted of 66 patients aged 3-6 years old with at least 2 white spot lesions in their primary anterior teeth who are assigned into control group (n=22): colgate fluoride varnish, test group 1(n=22): MI varnish and test group 2 (n=22) :curodont repair fluoride plus. Each material is applied once every 2 weeks for 3 times (intensive mode of application). The secondary aim of the study is to determine the antibacterial effect of each material against streptococcus mutans is compared by obtaining a plaque sample at baseline then after application by 48 hours, 1 months and 3 months and culturing using disk diffusion method for determining the log count of streptococcus mutans at each time point. Another secondary aim is to determine the change in lesion size at baseline and after 6 months and 12 months using standardized photographs with a digital camera.

Arm && Interventions

Group	Intervention	Description
CPP-ACPF varnish	Casein phosphopeptide amorphous calcium phosphate	casein phoshphopeptide amorphous calcium phosphate fluoride (CPP-ACPF )
5 % sodium fluoride varnish	5% sodium fluoride varnish	5% sodium fluoride varnish
curodont repair fluoride plus	self assmbling peptide p11-4 combined with 0.05% fluoride	self-assembling peptide (p11-4) with 0.05% sodium fluoride

Primary Outcome Measures

Name	Time	Method
Assessing the remineralization of early carious lesions in primary teeth	3,6,9 and12 months	comparing the remineralization effect of different remineralizing agents both qualitatively by comparing the change in ICDAS -11 criteria and quantitatively by using laser fluorescence scores using kavo DIAGNOdent classic after intensive mode of application of the different remineralizing agents

Secondary Outcome Measures

Name	Time	Method
comparing the antibacterial effect of different remineralizing agents against streptococcus mutans	3 months	Supragingival plaque samples will be collected at baseline then after 48 hours, 1 months and 3 months of application of the materials in an intensive mode. log count of streptococcus mutans is determined using disk diffusion method using mitis salivaris agar plates
comparing the change in esthetic appearance of early carious lesion before and after treatment	12 months	comparing the change in lesion size using standardized photographs quantitatively by calculating pixel size of the lesion before treatment and after 6 and 12 months of intensive mode of application of the different remineralizing agents using ImageJ software program for image analysis. Assessing the esthetic appearance of the lesions will be done subjectively by using a visual analogue scale score from 1 to 7
