Dental examination was carried out in 840 children aged from 5 to 11 years according to generally accepted indices. Among them 208 (24.8%) had precocious eruption of secondary teeth. Coccal flora (in 58.8%), less often Neisseria (in 13.7%), fungi of the genus Candida (in 11.4%) and lactobacilli (in 10.5%) were discharged from the dental plaque of these teeth. With regular oral hygiene of children, the amount of oral microflora significantly (P <0.05) decreases.
Preparation of deep fissures of precocious erupted permanent teeth with Er: YAG laser beams followed by sealing them with a light-cured composite sealant "X-flow" results in a reduction of caries in 93.4% of children, when using «Fis-Seal» sealant - in 79.7% of children.
