SUMMARY

The aim of the study was to determine the efficiency of the applied preventive measures during pregnancy and to improve oral health status to pregnant women. Material and Methods. Oral health status of 180 pregnant women was determined according to WHO criteria (WHO: Basic methods, 1997). Dental caries prevalence, DMF-T and DMF-S were evaluated. Gingival status was estimated according to Silness-Loe (GI) index. Women were asked about tooth brushing frequency; oral hygiene was evaluated according to Green-Vermilion (OHI-S) index. Participants were divided into test (89) and control (91) groups. During pregnancy, the following preventive measures were applied to the test group: fluoride varnish applications, mouthrinsing with 0.12 % chlorhexine digluconate, professional oral hygiene. Results. Oral health status was evaluated three times during pregnancy. Reduction in dental caries increment of the test group was 56.25 % in comparison with the control group. The periodontal status has improved, oral hygiene index (OHI-S) has decreased from 1.48±0.05 to 0.94±0.06 in the test group, and from 1.49±0.06 to 1.9±0.06 in the control group. Conclusion. Results of the study showed that selected dental caries preventive measures were effective and significantl
