ABSTRACT
The purpose of this feasibility study was to investigate the correlation of a salivary occult blood test (SOBT) with traditional periodontal measures to assess the feasibility of the SOBT as a measure of periodontal inflammation in a population of women during pregnancy. Considering the limitations of the previous SOBT studies, this study evaluated correlation of the Perioscreen Sunstar SOBT with traditional measures from a full mouth periodontal examination. Data were collected 3 times during pregnancy (12-14, 24-28, and 36 weeks) from women participating in an ongoing study of pregnancy and inflammation. Descriptive statistics and correlations were generated for SOBT scores with periodontal measures. Preliminary data were analyzed from 7 women with 3 visits, 7 with 2, and 9 with 1 visit. For these 44 visits' data, the mean percent of sites with bleeding on probing (BOP) for SOBT scores = 0, 2, and 5 was 58% ± 18%, 68% ± 14%, and 72% ± 19%, respectively. Correlations for percent of sites with BOP and continuous SOBT score was 0.301, P-value = 0.0469 and dichotomous SOBT was 0.32, P-value = 0.0339. Results for feasibility, measured as recruitment of participants, acceptance of protocols, distribution of periodontal inflammation and preliminary correlations, support SOBT as a correlated marker of periodontal inflammation in this population of pregnant women.
