|
Objectives: The aims of this study were to examine the oral malodor status, and relationship of oral malodor to socio-demographic factors, dental health behavioral characteristics and dental conditions in Vietnamese dental patients.
Materials and Methods: The subjects were 243 patients aged 30 to 60 years who visited the National Hospital of
Odonto-Stomatology in Hochiminh City. Oral malodor was measured by the organoleptic method and using Oral
ChromaTM. The socio-demographic and dental health behavioral characteristics were investigated by a questionnaire. Oral examination including dental and periodontal conditions, oral hygiene status, and saliva were examined.
Results: Prevalence of oral malodor diagnosed by the organoleptic method was 69.2%. The risk factors related to oral malodor were level of education (OR=3.18), dental visit behavior (OR=4.97), deep pockets (OR=5.35), gingival bleeding
(OR=3.37), thickness of tongue coating (OR=4.44), salivary flow rate (OR=4.80) and pH of saliva (OR=3.93).
Conclusion: There was a high prevalence of oral malodor, which was associated with oral and behavioral factors in Vietnamese dental patients. The effective treatment of periodontal disease, improvement of oral hygiene condition and appropriate oral health education are all important to ameliorate oral malodor and improve oral health.
