Objective: This study was planned with the aim of investigation of the effects of nutritional habits on oral health and lactobacillus species in oral flora in school aged children.

Study design/ methodology: This study was carried out with the participation of 112 children aged 6-14 and their parents who applied to the Pedodontics Clinic Dental Faculty of Marmara University. An evaluation questionnaire was used as a data collection tool and 24-hour recall food consumption records of participants were collected. Saliva samples were collected from participants who had anthropometric measurements. Dental examinations were performed with children participated in the study.

Findings: 44,6% of the children were male and 5,4% were female. While 56,3% of the children had normal BMI, 36.6% were overweight-obese and 7.1% were weak. When children's dietary qualities were evaluated according to the Healthy Eating Index, it was found that 89,3% were "poor diet" and 10,7% were "moderate diet". It was determined that 11,6% of the children could not have a toothbrushing habit. It was determined that 85,7% of the children participating in the study had at least one decay, 88,4% had at least one filled and 6,3% had at least one missing teeth. Median of the DMFT index were 6,0 and there was no significant difference between boys and girls (p>0,05). There was a positive correlation between the DMFS index and the number of main meals in children (p<0,05). Average of DMFS index of children who consumed fruit as a snack was higher than children who do not consume fruit (p<0,05). There was a negatively weak correlation between the BMI of children and the number of caries (p<0,001) and DMFS index (p<0,05). Lactobacillus was detected in 5% of children receiving saliva, and the number of decay in children who were lactobacilli was higher in saliva samples than in children without lactobacilli (p<0,05).

Results: Unhealthy snacks that cause excessive weight gain and increased BMI in children should be restricted to high calorie food consumption and children should be encouraged to have healthy eating habits.
