Objective: The objectives of this study was to assess oral malodor in edentate elderly who wear and do not wear dentures, and to analyze its association with socio-economic status, oral health, oral and denture hygiene.
Methods: One hundred eighty-four edentate elderly who lived in Phitsanulok, Thailand (39 male, 145 female, mean age= 71.28±6.06 years), were participated in this study. Oral malodor was assessed using the organoleptic test (OT) and Oral ChromaTM. Oral examination and salivary flow rate were conducted. Participants were given a self-administered, structured questionnaire to collect sociodemographic status, educational level, economic status, medical history, oral and denture hygiene behaviors.
Results: The prevalence of oral malodor by OT, H2S, CH3SH, (CH3)2S criteria were 69.6%, 58.2%, 17.4%, and 74.8%, respectively. Subjects who wear dentures were more likely to have a higher prevalence and higher concentration of H2S and (CH3)2S than those who do not wear dentures. Logistic regression analysis showed that the tongue coating was related with OT and H2S in both group of subjects. Quality of dentures was associated with OT and (CH3)2S (p＜0.05). Dentures worn overnight was associated with OT and H2S (p＜0.05). Systemic disease and intake of medicine were associated with (CH3)2S (p＜0.05).
Conclusion: Wearing a denture was a significant source of oral malodor especially poor quality dentures and the overnight use. Professional care to ensure quality of dentures and self-care for oral and denture hygiene education is important in this age group for preventing oral malodor.
