Abstract

ABSTRACT
Objective: Tongue coating is a common aetiology of oral malodour which affects the social, psychological and
social wellbeing of an individual. Despite the potential negative impact of tongue coating on the individual, its
management is still far from the ideal. It is therefore necessary to critically assess the level of coating of the
tongue. The objective of the study was to determine the prevalence of tongue coating and oral malodour
among University of Benin undergraduate students and the age/ gender variation in their level of coating and
oral malodour.
Methods: This observational cross-sectional study was carried out using 425 undergraduate students of the
University of Benin. An interviewer-administered questionnaire was used to elicit information on the
participants' demographic characteristics, perceived oral malodour, tongue cleaning aids and frequency of
tongue cleaning. Tongue coating assessment was done using the Kojima index of tongue coating and
organoleptic assessment was used to measure participants' level of oral malodour.
Results: The prevalence of tongue coating was 13.9%. Majority of participants with tongue coating (66.1%)
had thin coating of more than one third but less than two thirds of the tongue or a thick coating of less than one
third of the tongue dorsum. The age and gender distribution of tongue coating was not statistically significant.
The prevalence of oral malodour among the study participant was also 17.9%. Only 34.2% of cases of
malodour were not self- perceived. More of the study participants (55.6%) in the age group > 30 years had
barely noticeable malodour, 36.4 % in the age group 24-30 years had moderate oral malodour while 38.9 % in
the age group 15-23 years had slight but noticeable oral malodour (P=0.005). More persons among the males
(41.0%) and females (37.8%) had barely noticeable malodour (P= 0.886)
Conclusion: The prevalence of tongue coating and oral malodour among the studied undergraduate students
is low. There was no statistically significant relationship between age/ gender and the level of tongue coating
of the study participants but the variation in the level of malodour across the age groups in this study was
statistically significant.
