Effect of Nutritional Habits on Oral Microbiota in Adolescents

Oral microbiota; While it is associated with systemic diseases such as obesity, diabetes and cancer, it is also associated with oral diseases such as oral cancers, tooth decay and gum diseases. Nutrition is seen as an important factor in maintaining oral health. In particular, the amount and frequency of sugar consumption, the type and consistency of food, the frequency of eating, the consumption of cariogenic foods with other foods and the duration of carbohydrates remaining on the teeth are among the factors that affect oral health. The aim of this study is to examine the relationship between oral microbiota and eating habits, sleep quality and hedonic hunger in adolescents. The study is planned to be carried out in 4 stages. First stage; A survey form will be filled out that questions general information about children, oral health practices, nutritional habits and frequency of food consumption. In the second stage; Children's anthropometric measurements (body weight (kg), height (cm), waist circumference (cm) will be taken and bioelectrical impedance analysis (BIA) results will be recorded. In the third stage, oral examinations of the children will be performed. In the final stage, saliva samples of the children will be collected. Bacteria Logarithmic values will be used when comparing the concentrations between groups. The suitability of the parameters to normal distribution will be evaluated with q-q graphs and Shapiro-Wilk test. Student t test will be used for variables that comply with normal distribution and Mann Whitney U test will be used for changes that do not comply with normal distribution. The relationship will be evaluated with the Spearman or Pearson correlation test according to the normality distribution. IBM SPSS (Statistical Package for Social Sciences) 22.0 package program will be used when evaluating the data obtained as a result of the study. While examining the hypothesis tests, α = 0.05 and accordingly the confidence interval will be determined as 95%. It will be evaluated at p<0.05 level. In order to enable healthy adolescents to reach a good standard of living, there is a need for a more accurate understanding of the relationship between oral microbiota, nutrition and sleep. As a result of this study, it is aimed to reveal the relationship between oral microbiota and eating habits, sleep quality and hedonic hunger in adolescents.
