title: A cytologic study of the effect of Kolanut on the keratinization of the palatal mucosal of Nigerian smokers.
abstract: An exfoliative cytologic study of the palatal mucosa was undertaken in 96 Nigerian male volunteers aged between 17 and 65 years. The volunteers were categorised into the following four groups: Group 1--Smokers, kolanut chewers; Group 2--Smokers; Group 3--Kolanut chewers; and Group 4--Non-smokers, non-kolanut chewers, Variation in the degree of palatal keratinization was evaluated using karyopyknotic indices. Statistical analysis based on one way analysis of variance showed that smoking and kolanut chewing had a statistically significant influence (P less than 0.05) on the variation of palatal keratinization among the volunteers. Distribution of karyopyknotic indices among groups was such that Group 1 greater than Group 2 greater than Group 3 greater than Group 4. Observation from this study suggests a potentiation of the cigarette smoking-induced palatal keratinization by kolanut.
