Introduction:
There is a notable lack of scientific data on the prevalence and risk factors of halitosis among monastic populations. This study aimed to determine the prevalence of halitosis and its associated risk factors among monastic residents in Vietnam.
Methods:
A cross-sectional study was conducted in four monasteries, enrolling 47 monks and 71 nuns. Data on demographics, oral hygiene behaviors, and clinical oral health status were collected through questionnaires and dental examinations. Halitosis was assessed using both organoleptic evaluation and self-reported measures. Logistic regression was used to identify predictors of halitosis.
Results:
The prevalence of halitosis was 50.8% by organoleptic test and self-report. Higher debris index, calculus index, and tongue coating were the strongest predictors of halitosis, while periodontal parameters showed weaker associations. Poor oral hygiene practices, including infrequent brushing and neglecting tongue cleaning, were also associated with increased halitosis.
Conclusion:
Oral hygiene factors, particularly plaque, calculus, and tongue coating, are the strongest predictors of halitosis among Vietnamese monastic residents. Improved oral hygiene education and regular professional care are essential to reduce halitosis in this population.
