    Assessment of periodontal status and treatment needs of a disabled population using the CPITN
    (1999) Bamjee, Y.; Chikte, U. M. E.; Cleaton-Jones, P. E.
    The Community Periodontal Index of Treatment Needs (CPITN) was used to assess the periodontal status of 213 handicapped persons attending seven institutions in Johannesburg. Fewer than 2% had healthy mouths, 8% had bleeding only, followed by calculus (46%), shallow pockets (40%) and deep pockets (4%). The mean number of sextants with bleeding or higher score was 5.9. Oral hygiene instruction was indicated for 98% and prophylaxis for 90% of the participants. The CPITN was easily used in the disabled population but may overestimate treatment need in view of the current understanding that periodontal disease does not automatically progress from a low CPITN level to the next. A more appropriate measure of treatment need in handicapped persons is required

    Use of DI-S and CPITN as predictors in dental caries studies in the primary dentition
    (1991) Cleaton-Jones, P.; Hargreaves, J. A.; Beere, D.; et al.
    The DI-S (simplified oral debris index), CPITN (Community Periodontal Index of Treatment Needs) and dmfs (dental caries experience in the primary dentition were recorded in 395 5-year-old black children living in rural and urban areas of Southern Africa. The DI-S and CPITN were grouped, independently and together, to examine their use as simple field methods of predicting dental caries. For each grouping the sensitivity, specificity and positive and negative predictor values were calculated. A CPITN grouping of 0 or of two or more sextants with bleeding, provided the most convenient specificity, sensitivity and predictor values. It is recommended that this simple method should now be used in prospective studies of caries activity.
