RESUMO
PURPOSE: To investigate the oral health and hygiene behavior of chronic renal failure(CRF) patients in Shenzhen, so as to provide basis for formulating education for them. METHODS: The history of renal failure, oral health status and oral health care behavior of 336 patients with chronic renal failure(CRF) in the hemodialysis center of Shenzhen Second People's Hospital were investigated by questionnaire and oral examinations. RESULTS: At an average, dialysis was required for 3.2 years. The main cause of renal failure was glomerulonephritis in 49.11% of patients, hypertensive kidney lesion in 19.35% and diabetic nephropathy in 15.77% of patients; 77.8% of them kept brushing teeth two or more than two times every day; 72.9% patients suffered from oral problems such as toothache in recent 12 months. The rate of visiting a dentist when having complaints was 21.7%. CONCLUSIONS: The state of oral health of CRF is worse than the general population of comparable age in China, while their hygiene behavior is better than the corresponding reference general population. However, their consciousness of dental treatment is poor. Therefore, health education for CRF patients should include knowledge about oral diseases complicated with CRF and correct medical philosophy.
