Oral health in Latvian 15-year-olds.

Oral hygiene, caries and periodontal conditions were assessed in a representative sample of 15-year-old Latvian schoolchildren, comprising 506 subjects. Caries, diagnosed on the cavity level, was detected in 97.6% of the population. The mean DMFT and DMFS were 8.1 and 14.1, respectively. Although 91% of the children had had restorative treatment, the D component accounted on average for 33% of the DMFS score. Visible dental plaque was found in 98.4% of the children; in a majority (88%) abundant plaque deposits were recorded. Community Periodontal Index of Treatment Needs (CPITN) was assessed by standard WHO methods. Deviation from periodontal health was observed in 90.7% of the children. Calculus was recorded in 26.1% and gingival pockets in 25.9% of the sample. Additionally, 38.7% of the children had gingival bleeding. The mean number of sextants with healthy periodontal conditions was 2.5. Calculus and pocketing averaged 0.6 and 0.4 sextants, respectively. Attachment loss, recorded in 11.7% of the subjects, did not exceed 3 mm. The results showed high caries prevalence, considerable need for treatment and virtual absence of oral hygiene.
