Table 2. Testing of mean deft between NSC-330507 adjacent age groups. The greatest contribution to the deft index was untreated caries, which varied from 2.04 for two-year-olds to 6.37 for five-year-olds. Six-year-old children showed a slight decrease (6.09) (Table 3). Table 3. The deft structure of preschool children. The 1,237 examined preschool children revealed an early childhood caries (ECC) prevalence of 17.6% (179 children). The mean deft value for children with ECC was 10.6 (Table 4). Table 4. ECC prevalence by gender in preschool children and its comparison. Even though boys had a higher ECC prevalence, we did not find any statistically significant differences in the ECC prevalence between genders (T-test=1.664, p=0.096). The percentage of caries-free children (DMFT=0) at the age of six was 13.

3%, and as expected, this decreased with increasing age. At 14 years old, only 0.9% were caries-free. The mean DMFT index was 4.86 for all school children. The increase in the mean DMFT was related to age, increasing from 2.36 for 7-year-olds to 6.91 for 14-year-olds. There was no significant difference between the genders for any age group (Table 5). Table 5. Caries prevalence, mean DMFT and comparison of mean DMFT between genders in school children. The mean DMFT of school children increased with age, with a statistically significant difference between the age groups tested with ANOVA (F=290.83, P<.001). The differences between adjacent age groups showed a difference for 7-year-olds vs. 8-yearolds, 9-year-olds vs. 10-year-olds, 10-year-olds vs.

11-year-olds, 11-year-olds vs. 12-year-olds, and 12-year-olds vs. 13-year-olds (P<.0001). There was no difference for 8-year-olds vs. 9-year-olds (P>.05) or 13-year-olds vs. 14-year-olds (P>.05) (Table 6). Table 6. Testing of mean DMFT between adjacent age groups. The greatest contribution to the DMFT index was untreated caries, which varied from 2.10 for 7-year-olds to 5.00 for 14-year-olds (Table 7). Table 7. The DMFT structure of school children. First permanent molars were the most decayed teeth with a high prevalence (97%). The DMFT index related to the first permanent molar was 3, where 82.4% were decayed, 8.3% lost due to decay, and only 9.3% were treated (Table 8). Table 8. Caries prevalence and DMFT structure for first permanent molar (M1).

The interview involved 446 school children and 418 preschool children (with the help of the parents or teachers). The results from the questionnaire showed that 73% of the children have had a dental visit at least once in their lifetime. The most common reason for Dacomitinib that visit was a toothache (69%), and 66% of the children had a bad experience while visiting the dentist. Oral health classes were not organized at any of the schools, even in those with existing dental offices. Concerning the consumption of sweets, 58% of the children responded that they consumed sweet snacks at least twice a day.
