An analysis of the community periodontal index of treatment needs. Studies on adults in France. V. Presentation of CPITN data in cross-tabulations.
A total of 1005 subjects were examined using the CPITN and DFT indices. CPITN data were modified in their presentation in order to be suitable for cross-tabulation. Two different methods were considered. One, described previously by Roland et al. (1984), classified subjects according to the combination of their highest CPITN score and the mean of the highest scores of every nonedentulous sextant. The other consisted of multiplying the above mentioned mean by the individual's highest CPITN score. A critical analysis of the methodology showed that the two number system developed by Roland et al. (1984) was impractical. The new method provides a linear array of values from 0 to 16. Very little overlapping of values was observed, which means that a relatively precise periodontal condition is characterised by each value. With this transformation the CPITN can be used as an index that quantifies periodontal conditions instead of treatment needs.
