Determining the relationship between the use of food supplements and tooth decay based on DMFT Index

Abstract

Tooth decay has become one of the widespread problems in today's society. Therefore, paying attention to oral and dental health and identifying factors affecting its health has become one of the biggest challenges in the field of dentistry. Therefore, this research investigates and determines the relationship between the consumption of food supplements and tooth decay based on the DMFT index, using the data obtained from the statistical population of the Azar cohort. The statistical population of the study includes people aged 70-35. From the population of 15006 people of Azar cohort, taking into account the entry and exit criteria, 8495 people were included in the study. Among them, there are 3969 men and 5026 women, where men make up 46.7% of the volume of Monet and women make up 53.3% of it. The nature of this research is cross-sectional-analytical and the required data were obtained through questionnaires and self-reports. Data analysis was done with SPSS software version 22. The accepted significance level was considered below 0.05. For descriptive analysis, mean and standard deviation were used for quantitative variables, and frequency and percentage were used for qualitative variables. Comparison of average DMFT based on variables of consumption of nutritional supplements was done using T-test and regression. Variables such as age, gender, socio-economic status, education level, frequency of brushing teeth, smoking, alcohol consumption, body mass index (BMI), diabetes, cardiovascular diseases, respiratory diseases and fatty liver are also used to moderate the effect. Confounding factors were also analyzed by regression to increase the level of confidence in the research findings. The findings indicate that there is a significant relationship between the consumption of folic acid and iron supplements with the DMFT index, but no significant relationship was observed between the consumption of multivitamins, minerals, zinc, calcium, vitamin D and omega-3. Therefore, based on the findings, it can be said that the inclusion of some supplements in people's diet can lead to a decrease in the DMFT index, while other supplements are also useful in terms of nutritional value. At the end, suggestions were presented for use in the executive fields of health and hygiene.
