Abstract :Purpose Understanding how increased level of salivary cortisol contributes to the development of dental biofilm during pregnancy can help inthe prevention of dental caries and periodontal diseases. This study aims to evaluate the relationship between salivary cortisol level and dental biofilm formation in pregnant women. Patients and Methods This descriptive-analytic study was conducted in Hamadan, Iran in 2011. Forty consecutive pregnant women with no history of abortion, stillbirth, or any known physical or psychological disorders at weeks 25 and 33 of gestation were included. Salivary samples were collected for measurement of cortisol levels by Enzyme Linked Immunoabsorbent Assay insert ignore into journalissuearticles values(ELISA); method. The amount and extension of dental biofilms were determined by using a disclosing agent. Data were analyzed using descriptive and analytical statistics in SPSS version 16. Results The mean levels of salivary cortisol at weeks 25 and 33 of gestation were respectively, 2.45 ± 1.56 µg/dl and 5.24 ± 4.07 µg/dl which demonstrates a significant difference insert ignore into journalissuearticles values(P<0.001);. Evaluation of dental biofilm at two time intervals revealed a significant increase in amount of dental biofilm at week 33 of gestational period insert ignore into journalissuearticles values(34.65 ± 10.9% vs. 42.45 ± 12.35%, P<0.001);. Elevated levels of dental biofilm were significantly correlated with salivary cortisol levels at week 33 insert ignore into journalissuearticles values(r=0.494, P=0.001);,however, it was not significant at week 25 of gestation insert ignore into journalissuearticles values(r=0.148, P=0.361);. Conclusion The findings suggested that increased levels of salivary cortisol can predict dental biofilm formation and accumulation in pregnant women in the last weeks of gestation.
