Introduction. Reproductive period in women begins with the occurrence of the first menstruation and ends with the cessation thereof. The latter occurs at different age of women, depending on many factors such as race, geographical or living conditions and so on. At this time, many processes affect the condition of mineralized tissues in a woman’s body.
Aim. The aim of the study was to investigate the influence of reproductive period (fertility, lactation, age of menopause) on the parameters of bone tissue and hard tissues of teeth in peri- and postmenopausal women.
Material and methods. The study involved 112 women aged 45-74 years. There was conducted a survey and a clinical study. Patients were asked about the number of pregnancies and offspring, the duration of lactation in case of each child, the age at which the menopause occurred. Periods of pregnancies and lactation were recorded in months. The bone mineral density, the number of teeth present in the mouth were also evaluated, and the DMFT index was calculated.
Results. In the studied groups of women a significant correlation between the bone mineral density and the T-score and the age at which menopause occurred was observed. Also, a significant correlation between the number of offspring and the number of the DMFT index, the number of offspring and component MT of the DMFT index and the number of offspring and the number of teeth present in the mouth during the study. A significant positive correlation between the duration of pregnancies and lactation and the DMFT index, the component MT and the number of teeth present in the mouth during the study, was observed.
Conclusions. In the studied population of peri- and postmenopausal women, a possible impact of reproductive period on the parameters of the state of the bones and teeth – the longer the total duration of pregnancy and breastfeeding and early age of onset of menopause concerned worse parameters of mineralized tissues – with the higher number of DMFT index and lower bone mineral density were observed.
