The effects of maternal use of medicines during pregnancy on tooth development has scarcely been studied; only negative effects of tetracycline on tooth germs are known (irreversible tooth discoloration and enamel hypoplasia).
The aim of this study was to investigate whether antibacterials and anti-allergic and anti-asthma medicines, being the most frequently used medicines during pregnancy, are associated with deciduous molar hypomineralisation (DMH) and, if so, which specific medicines.
Materials and Methods
To clarify this possible association, the participants of the Generation R Study, a population-based prospective cohort study from fetal life until young adulthood, were studied. Data on medicine use during pregnancy were retrieved from pharmacies. Clinical photographs of the second primary molars, which were scored for DMH, were taken with an intra-oral camera in 6,690 children (mean age 6.2 years, standard deviation [SD] ± 0.53; 49.9 % girls).
During pregnancy, 20.3 % of the mothers used antibacterials, 12.3 % anti-asthma medicines and 5.4 % anti-allergic medicines. The prevalence of DMH was 9.0 % in the study group. There was no association between the use of anti-asthma medicines, anti-allergic medicines (odds ratio [OR]: 0.97 [95 % CI 0.61-1.54]; OR: 1.04 [0.54-2.03]) or antibacterials (OR: 0.73 [0.49-1.09]) during pregnancy and DMH (all p-values >0.05). The study had sufficient power (80 %) to detect significant associations.
Maternal use of antibacterials, anti-allergic medicines or anti-asthma medicines during pregnancy is not associated with the development of DMH in the offspring.
