ABSTRACT
Objective:To study the risk factors of salivary occult blood in Tianjin public security police, and to explore feasible oral preventive and health care measures for police officers.Methods:The public security officers from all districts and counties of Tianjin who had physical examinations at the Health Examination Center of Tianjin Public Security Hospital from March 2012 to November 2012 were selected as the research objects. A stratified cluster random sampling method was used to draw samples of 388 cases. The salivary occult blood test paper was used to detect salivary occult blood. Then the self-designed "Tianjin public security police periodontal health questionnaire" was used to collect the relevant data of the subjects, and univariate analysis and multivariate unconditional Logistic regression analysis were carried out.Results:The univariate analysis result showed that salivary occult blood was significant correlated with age, police species, history of gingival bleeding, history of halitosis, history of alcohol consumption, family history and soft food preference (all P<0.005), but it was not correlated with education level, a regular oral examination, times of brushing teeth every day, time of brushing teeth every time, smoking history, hard food preference, sweet tooth preference and carbonated drinks preference(all P>0.05). Multivariate unconditional Logistic regression analysis result showed that criminal police, age, history of gingival bleeding, halitosis, smoking history were risk factors for periodontal disease, and brushing time of 2~3 minutes was protective factor for periodontal disease. Conclusions:The public security police lack the knowledge of oral health care and have not formed good daily oral health habits. Medical workers should carry out targeted oral health education to improve the awareness of the prevention and treatment of periodontal disease.
