Master Title

Correlation between body mass index and severe early childhood caries in a group of preschool children in Ismailia city

Master Abstract

Summary This study was conducted to investigate possible correlation between body mass index (BMI) and severe early childhood caries (S-ECC) in a group of preschool children in Ismailia city. 2356 preschool children were examined. According to the inclusion criteria, only 405 preschool children were included, 221 boys and 184 girls. 196 children were from nurseries, 148 were from kindergartens of 4 private schools & 61 from kindergartens of 3 public schools. Their age ranged from 24 to71 months. Those children were examined for dental caries which was identified using (dmfs) index. Diet history questionnaires were distributed among the examined children. From the charts the number of snacks/day were calculated then correlated with dental caries experience. Additional information were obtained using questionnaires, investigating about oral hygiene habits as brushing frequency & age of beginning tooth brushing; the mother’s education level as an indicator of the socioeconomic level of the family and history of the child’s feeding. Anthropometric measurements (weight and height) were taken and the body mass index (BMI) was calculated. The calculations were plotted on the age and gender specific Egyptian growth charts 2002 (2-21 years) and the children were categorized into 4 BMI groups (underweight, healthy weight, overweight and obese). The results of this study showed that the BMI was not correlated with (dmfs) scores of preschool children with S-ECC. The distribution of children in BMI categories was: 3% underweight (N=12); 66.7% normal weight (N=270); 19.8% overweight (N=80) and 10.6% obese (N=43). The caries prevalence was increasing with age and boys had higher caries scores (dmfs) than girls. It was found that children who had brushed their teeth (1or 2 times/ day), had the fewest dmfs scores compared to those who had occasionally or never brushed their teeth. There was no statistically significant correlation between the frequency of snacks intake and the caries prevalence.

Clinical, Radiographical and Microbiological Evaluation of Chitosan as Irrigating Solution for Pulpectomy in Non-Vital Primary Teeth

PHD Abstract

Summary The aim of this study was to evaluate chitosan as irrigating solution for pulpectomy in non-vital primary teeth (clinical, radiographical and microbiological study). The 45 non-vital primary molars were randomly divided into 3 equal groups. Each group involved 15 molars either primary first or second molar. Group I (control group), the teeth were irrigated by 2 ml of 1% NaOCl after each file. Group II, the teeth were irrigated by 2 ml of 1% NaOCl after each file then with 5 ml of 0.2% chitosan and left in the canal for one minute. Group III, the teeth were irrigated by 2 ml of 1% NaOCl after each file then with 5 ml of 0.2% chitosan and left in the canal for 3 minutes. Clinical evaluation was done after 1,3,6,12 months follow up intervals and the following parameters were evaluated: spontaneous pain, pain on percussion, abnormal mobility, any changes at the muco-buccal fold. Radiographical evaluation was done at 3,6,12 months follow up intervals using standardized periapical radiographs and analyzed using Image J program. One-way ANOVA followed by Tukey post hoc test was used to compare between more than two groups in non-related samples. Two-way ANOVA test were used to test the interactions between different variables. The significance level was set at P = 0.05. Statistical analysis was performed with IBM® SPSS® Statistics Version 20 for Windows. It was found that sodium hypochlorite followed by 0.2% chitosan as a final irrigation for 3 minutes, has more efficacy to eradicate Enterococcus faecalis in comparison with sodium hypochlorite alone regarding microbiological evaluation. Although the Chitosan 0.2% significantly increase the antibacterial ability against Enterococcus faecalis when used as supplementary irrigation with sodium hypochlorite in pulpectomy in deciduous molars, there was no significant difference between groups regarding the clinical and the radiographical success.
