Abstract

Objectives: The purpose of this study was to evaluate objective and subjective perception of oral health status, oral hygiene behaviors, and salivary mutans streptococci(MS) levels of pregnant women in Korea. Methods: The subjects of this study who attended programs of pregnant woman were collected from Dec. 2004 to Nov. 2005 in Daegu city. Questionnaire survey was also performed for subjective oral health perception, oral hygiene behaviors, and utilization of dental clinic. The status of decayed, missing, and filled teeth(DMFT), community periodontal index(CPI) were assessed by clinical oral examinations. The MS and S.mutans levels of stimulated saliva were evaluated using Mitis Salivarius Bacitracin selective media. Results: There were a total of 109 subjects in this study. The sixty-six percents of subjects reported that they did not have good oral health. The fifty-five percents of subjects brushed their teeth over 3 times per day. The eighty-four percents of subjects did not visit the dental clinic within 6 months. The mean DMFT and DMFS were 7.7 and 15.8 respectively. For these subjects, dental calculus(50.5%) and gingival bleeding(34.3%) were most frequent. Severe periodontal condition were relatively rare. The salivary CFUs of MS and S.mutans were 6.9×106 CFUs/㎖ and 0.8×106 in MSB media. There were 32.1% of subjects who had CFUs of MS between 1×105 and 1×106 CFUs/㎖ with a peak value. There were 56.9% of subjects who had CFUs of S.mutans under 5×104 CFUs/㎖ with a peak value. Conclusions: The gingival bleeding was prevalent in the pregnant. The pregnancy would increase the risk of gingival bleeding and periodontal disease.
