Aim: To evaluate the index (OHI-S) of two groups of children from 4 to 6 years of age after application of solution and gel for oral hygiene.

Material and Methods: Object of observation – N= 300 children from the city of Varna aged 4 to 6 years, distributed equally in standardized age groups, with the same number of boys and girls. They were divided into two groups for determination of OHI-S(PLI) of Greene-Vermilion for 1 - control group (N=91), against determination of OHI-S(PLI) of Greene-Vermilion for 2 - study group with Oroben(Aboca) fluid and gel (N=209). The study was conducted at the Faculty of Dental Medicine, Varna, 2021, with informed consent from each parent. The choice of children is random. All carious (d), missing (m) and filled teeth (f) are recorded. The presence of plaque after staining on the respective surfaces of the representative teeth was recorded. The STATISTICA 10.0 package specialized for statistical analyzes was used.

Results: The results of the t-test for statistical significance of the difference between the mean values of OHI-S(PLI)were measured after 8(weeks)and showed that OHI-S (PLI) = 1.590 for the control group versus OHI-S(PLI) = 0.723 for the study group with Oroben. A statistically significant difference was found in the mean values for OHI-S(PLI) as p-level=0.0000001<0.05 i.e. the hypothesis of equality of means is rejected at a significance level of 0.05.

Conclusions: The variables dft and OHI-S(PLI) influence one another directly and proportionally and also depend on the age factor of the patients.
