Abstract

Halitosis seriously affects the quality of life as well as social interaction of patients. The prevalence of halitosis in Vietnamese people is about 45%. Objective: Describe the current situation and some factors related to halitosis in patients aged 15 and over at Hanoi National University Hospital in 2023. Methods: A cross-sectional descriptive study was conducted on 140 patients aged 15 and over examined at the Dental and Maxillofacial Clinic from March to April 2023. The main variables were halitosis assessed by the breath perception index (OSI) and H₂S gas measurement using the Breath Checker. The results were analyzed and presented as frequencies and prevalence rates. Patients voluntarily agreed to participate in the study. Results: The prevalence of halitosis was 80%. Factors associated with halitosis include gingivitis (81.25%), poor oral hygiene (82.08%), and tongue plaque (84.38%). Moderate and severe levels of H₂S gas accounted for 34% and 26%, respectively. Factors such as smoking, drinking alcohol, drinking coffee, and eating odorous foods were significantly associated with halitosis. Conclusion: Halitosis is very common among patients treated at the dental clinics and hospitals, the main causes being poor oral hygiene, gingivitis, and tongue plaque, along with some factors related to the patient's lifestyle.
