Целью настоящего исследования было сравнить начало прорезывания первого молочного зуба у недоношенных детей различной массы тела на прорезывание зубов. Обследованы 120 младенцев — 81 недоношенных и 39 доношенных детей в возрасте от 5 до 36 месяцев, обоих полов.Резульаты были проанализированы с учетом биологического возраста и возраста после зачатия,или скорректированного возраста, который представляет собой гестационный возраст плюс хронологический возраст младенца в месяц прорезывания первого молочного зуба.

The purpose of this study was to compare the onset of eruption of the first milk tooth in premature infants (<37 weeks) with term infants (38 and 42 weeks) with normal birth weight (2900 g),low birth weight (<2900 g) and very low birth weight (<1499 g) to assess whether preterm labor and low birth weight may affect teething. Neonatal records and the time of first deciduous tooth eruption were recorded in 120 infants — aged 5 to 36 months, both sexes. All of them were being treated in the pediatric department of the RSNPMC. The results showed that,taking into account chronological age, teething in premature infants and very low birth weight infants is significantly delayed. However, when adjusted for age, no statistically significant differences were found between groups.
