The effect of an infant's environmental conditions and state of health on the teething of the primary incisors.

The objective of this research was to determine the relationship between the time when an infant’s first incisor teething occurred, the infant’s state of health and selected environmental and living conditions. 483 infants participated in this research and their health development was monitored monthly in a local hospital in Wroclaw. The teething of the infants was studied from the time of their birth until the age of 18 months. The descriptions of the infants’ living and environmental conditions and their developmental stages were analysed on the basis of 10 standardised characteristics. The results of this study showed that there were strong relationships between the teething of infants’ incisors, their living conditions and individual progress in health development.
