Objectives: To estimate the prevalence and severity of dental caries along with the treatment needs; to determine the factors that influence dental caries status among pregnant women attending a district maternity hospital in Udaipur, India. Study design: Study sample comprised of 206 pregnant women attending a district maternity hospital in Udaipur, India. Clinical data were collected on dental caries by DMFT and treatment needs as described in World Health Organization Dentition status and Treatment needs. Results: The overall caries prevalence was 87%. Mean caries experience differed significantly among women in various trimesters, it was found to be 3.59 and 3.00 in 1st and 2nd trimester subjects respectively while it was greatest (4.13) among those in 3rd trimester. One surface filling was the most predominant treatment need. Age and occupation of husband explained a variance of 6.8% and 4.2% for decayed and filled components respectively while the only predictor for missing teeth and DMFT that explained a variance of 9.6% and 5.7% respectively was trimester of pregnancy. Conclusions: Dental caries experience and the need for one surface restoration increased with age. Trimester of pregnancy was a significant predictor for missing teeth and DMFT, while decayed teeth and filled teeth were influenced by age and socio-economic level respectively.
