Abstract:Objective To study the association between oral hygiene status and oral cancer among non-smoking and non-drinking women. Methods We recruited 162 non-smoking and non-drinking female patients who were postoperatively pathologically confirmed as oral cancer in Department of Oral and Maxillofacial Surgery, the First People’s Hospital of Yibin City from October 2012 to September 2017. And 214 non-smoking and non-drinking healthy women were simultaneously selected from health examination center in the same hospital to serve as the control group. Oral hygiene related variables included the frequency of teeth brushing, number of teeth loss, poor prosthesis, regular dental visits and recurrent oral ulceration. Multivariate logistic regression model was used to analyze the association between the score of oral hygiene and the incidence of oral cancer in non-smoking and non-drinking female patients. Results Daily teeth brushing less than twice (OR=1.49, 95%CI:1.09-2.08), teeth loss more than or equal to 5 (OR=1.80, 95%CI:1.16-2.84), having poor prosthesis (OR=1.51, 95%CI:1.04-2.23), irregular dental visits (OR=1.74, 95%CI:1.16-2.57) and suffering recurrent oral ulceration (OR=7.29, 95%CI:3.98-13.35) were risk factors for oral cancer in non-smoking and non-drinking women (all P<0.05). Multivariate logistic regression analysis showed that the score of oral hygiene was associated with the occurrence of oral cancer in non-smoking and non-drinking female patients. The higher the score, the higher the risk (χ2=24.179, P<0.001). Conclusions There is a relationship between the status of oral hygiene and the occurrence of oral cancer in non-smoking and non-drinking women.
