Behavioral and socio-demographic risk factors for the development of dental caries in children from 3 to 6 years of age

Dobrinka Damyanova


Introduction: The risk profile is a general concept that includes different ways of assessing oral health. It can be made at several levels: public or group for a given population; individually; locally for certain teeth.

Aim: To identify the main risk factors for temporary teeth caries in the examined group of children, through a survey of their parents.

Materials and Methods: Assessment of standard risk factors for development of dental caries was conducted, as well as an assessment of the individual specific risk factors of each child. The objects of observation were parents of children from Varna and Varna district. The survey volume was 100 individuals. The units of observation were patients from 3 to 6 years of age requiring prophylaxis and treatment of dental caries of the temporary dentition.

We have identified the correlation between oral hygiene index (OHI), risk, age and decayed/missing/ filled teeth (DMFT) in temporary teeth - the Pearson Correlation Index. After processing the results and de-termining the highlights, the actual study was conducted by processing the data with a mathematical and statistical processing package SPSS v 20.0.

Results: Incidence of cariogenic plaque biofilm covering temporary teeth and surfaces was found in 100.0% of the children included in the study. From behavioral factors related to dental caries (r =-0.44 p<0.001), the use of carbohydrate (sugar) foods and beverages (r = 0.51 p <0.001) had moderate to strong influence on caries development. Of socio-demographic factors, only social status showed reverse proportional moderate dependence on the risk of caries development (r =-0.39 p<0.001). The lower the education of parents was, the higher the risk of developing caries was.

Conclusion: The analysis in our study demonstrates the strong impact of carbohydrate consumption and poor oral hygiene on the development and pro-gression of the carious process in the temporary dentition. Through all the factors examined, we found that children had a high risk of dental caries.
