Background. Today dental caries remains the main reason for seeing a dentist.
Aim. The aim of the study was to identify Risk Factors (RF) for Cervical Caries (CC) of teeth in young patients, their detailing and analysis.
Materials & Methods. There were examined 272 patients (mean age 24.3±6.9 years) whose biophysical parameters of Oral Fluid (OF) and level of personal anxiety were determined. Data on potential RF were collected using a questionnaire. To assess the strength of the correlation between the studied factors and the outcome, there was used the indicator of Odds Ratio (OR), for which the 95% Confidence Interval (95% CI) was determined. Univariate and multivariate logistic regression analysis were used to identify RF. The work was carried out within the framework of the dissertation research of the first author.
Research Ethics. The research was carried out based on the principles of World Medical Association Declaration of Helsinki (1964–2024), Order of the Ministry of Health of Ukraine No.690 of September 23, 2009, the conclusion of Bioethics Commission of Donetsk National Medical University No.43 of January 21, 2021. All participants gave a written informed consent in the study.
Results. Independent RF of development of CC of teeth were determined as salivary flow rate less than 0.5 ml/min, buffer capacity of OF less than 6.5 arb. u.; pathological type of bite and shortened frenulum of tongue; habit of adding lemon to tea; clinical markers occlusal abrasion and cracks in tooth enamel. Factors-modifiers of development of CC of teeth were average daily consumption of more than 0.25 portions of acidic foods and more than one glass of green tea; high level of personal anxiety; musculoskeletal dysfunction of temporomandibular joint lasting more than a year. Consumption of fruit in an average amount of 2.5 pieces and more than one cup of coffee per day had OR<1 that indicates their potential protective effect. The existence of confounding was determined for predictor "frequency of tооth brushing" more than twice a day. Independent RF of progression of CC of teeth were presence of three or more malpositioned teeth and a history of digestive diseases. However, in univariate analysis, both variables showed wide CI indicating instability of assessment.
Conclusions. The combination of logistic regression analysis methods allowed to distinguish between independent and latent predictors as well as to identify potentially protective factors and a confounding factor.
