Abstract
OBJECTIVE: To determine the association between maternal age at delivery and caries in offspring. MATERIALS AND METHODS: = 65,259) was examined to determine caries experience (deft scores) at 7 years of age. Age of mother at childbirth was retrieved from the patient histories. Data were analysed using linear regressions. RESULTS: The lowest mean deft occurred in children born to mothers aged 25-34 years. The final model - adjusted for sex, income, educational level, migration background, family situation, smoking, obesity, small for gestational age, and number of siblings - found that young mothers and older mothers were significant risk indicators for caries experience at 7 years of age. CONCLUSIONS: The present study found a U-shaped relationship between maternal age at childbirth and caries experience in the offspring at age 7 years. The offspring of mothers under 25 or over 34 years of age are at greater risk of having more teeth with caries experience.
