Comparative Analysis of Caries Lesions of Two Groups of Children By Clinical Examination with Laser Fluorescence

Background: Varnish, when brushed onto the teeth, provides a highly concentrated dose of fluoride and maintains prolonged contact with enamel to inhibit caries. Objective: Our study aims to evaluate the effect of mineralizing fluorine varnish on the progression of initial caries of enamel in temporary dentition by laser fluorescence. Material and Methods: Object of observation. 1 group 100 children aged 3, 4, 5 and 6 years treated with Clinpro TM White Varnish with TCP (Tri-Calcium phosphate) (3M) – CV. Two groups 100 children aged 3, 4, 5 and 6 years without treatment with varnish CV. Location of the study University Medical Dental Center Varna, Clinical Halls for Children's Dentistry, Faculty of Dental Medicine – Varna. Units of observation: Temporary teeth, Caries lesions at level d1 and d2. After processing the results and determination of the highlights was conducted by actual survey data processing package for mathematical and statistical analysis SPSS v 20.0. Results: A significant difference was found between the average lesion scores in the control and experimental groups after treatment with CV (t = 4.206, p = 0.001), whereas the children in the experimental group had a significant reduction in the lesions of the temporary central incisors. In the four-year-old children, we found a significant difference between the mean values of the treated children before and after non-invasive treatment with CV (t = 2.043, p < 0.01). The analysis of temporal canine lesion values in four-year-old children showed a significant difference between both the control group and the pretreatment group (t = 2.357, p = 0.001). Conclusion: 1. After the first week, DIAGNOdent pen scores improved from less than three steps for d1b and d2 lesions and improved by two steps for d1a lesions. 2. Increased therapeutic efficacy of dental agents for noninvasive treatment is achieved by enhancing them with fluorides.
