Abstract

Subjects The subjects in this cohort study were derived from a population of 67,355 pregnancies recruited to the Norwegian Mother and Child Cohort Study (MoBa) from January 2000 to April 2007. The final sample available for analysis included 48,989 women with a mean age of 29.6 years (SD 4.5). Information regarding health, education, marital status, alcohol consumption, smoking habits, and body mass index (BMI) for the pregnant women was obtained from a questionnaire that was completed by the study subjects at the 17th week of pregnancy. The self-assessed number of teeth and number of teeth with amalgam fillings were obtained in the 30th week of pregnancy, in addition to information regarding dental X-ray examination and dental restorative treatment during the first 30 weeks of pregnancy. Key Risk/Study Factor A number of exposure variables were evaluated, including age, education, smoking habits, alcohol consumption, and BMI to identify risk factors potentially associated with amalgam fillings in pregnant women. Main Outcome Measure The primary condition was self-report of number of teeth with amalgam fillings measured at the 30th week of pregnancy using a questionnaire. For the purposes of analysis, the outcome was a dichotomy0 to 12 teeth and more than 12 teeth. Main Results With respect to the outcome, statistically significant odds ratios were found univariately for age, education, BMI, and smoking. The level of significance increased for increasing ages, decreasing education, increasing BMI, and increasing smoking frequency. In a multivariate model, the same exposure variables were found to be independently significant. The validity of the self-assessment was measured through an external sample of 97 women whose self-assessments were compared with those from dental examinations. The results showed a high level of validity across levels of numbers of teeth with amalgam fillings. Conclusions The authors concluded that age, education, smoking habits, and BMI were associated with the number of teeth with amalgam fillings.
