Abstract
The purpose of this study was to determine the periodontal status and treatment needs, using the CPITN index, in a population aged 7 to 60 years residing in the fluorosis area of Khouribga and the non-fluorosis area of Beni-Mellal, Morocco. A total of 2378 subjects was studied. In the youngest age groups, more subjects and sextants from Khouribga than from Beni-Mellal were free of periodontal diseases. Conversely, in Beni-Mellal, subjects in the youngest age groups presented a higher mean number of sextants with calculus than those from Khouribga. In combining the 2 areas, 1.3% of the 2319 dentate subjects examined needed no treatment and 98.7% needed at least oral hygiene instructions (TN1). The present study, based on the CPITN index, demonstrated in both areas a high prevalence of gingivitis, and a relatively low prevalence of deep pocketing, occurring on the average in less than half a sextant in the total populations.
