INVESTIGATION OF THE EFFECTS OF NUTRITIONAL HABITS ON ORAL HEALTH AND SALIVARY PORPHYROMONAS GINGIVALIS AND BIFIDOBACTERIUM SPECIES IN CHILDREN
Objective: This study was planned to investigate the effects of nutritional habits on oral health and Porphyromonas gingivalis and Bifidobacterium species in children.
Study design/ methodology: 130 children aged between 9-14 years who applied to Marmara University Pedodontics Clinic were included in the study. Anthropometric measurements and oral examinations were performed. A questionnaire on nutritional habits and oral hygiene habits was applied, 24 hour diet records was taken and saliva samples were collected.
Findings: While 64.6% of the children had normal BMI, 19.2% were overweight and 10.8% were obese. It was seen that 22.3% of the children skipped meals and breakfast was the most skipped meal. There was a negative correlation between the number of primary teeth caries, dft/ dfs indexes with body weights/ height of the children (p<0,001). Gingival index scores were higher in children who consumed carbonated beverages (p<0,05). A negative correlation was found between total fiber intake and plaque index scores of children (p<0,05). There was a negative correlation between daily intakes of thiamine and vitamin B6 with DMFT index (p<0,05). While none of the children had Porphyromonas gingivalis in their saliva, 3.1% of the children had salivary Bifidobacterium. Children who had Bifidobacterium in their saliva had higher number of decayed primary teeth, dft /dfs indexes than children without salivary Bifidobacterium (p<0,001).
Results: Lifestyle habits such as healthy eating and limiting high energy snacks in childhood is important for the maintanence of oral health as well as general health.
