Degree of correlation between two periodontal indices in the Croatian rural population

The clinical study was performed in order to compare the periodontal status in patients measured by two indices - the Community Periodontal Index (CPI) and the Loss of Attachment (LA). The degree of correlation between them was determined. From a sample of 367 persons (1535 dentate sextants), patients 15+ years of age from two rural areas in Croatia, the Community Periodontal Index (CPI) and the Loss of Attachment (LA) was determined. The analytic units were person, sextant and jaw. Partial correlation between the CPI and LA indices was found. Cumulative for all age groups, sextants with a CPI code 0, 1 and 2 most often appeared with a LA 0-3mm (CPI 0 - 90%, CPI 1 - 88, 53%, CPI 2 - 63, 20% of sextants). Shallow pocket sextants (4-5mm) in 64, 04% also correlate with the loss of attachment values 4-5 mm. In deep pocket sextants (6-8 mm), a deviation from our expectations was found. They appeared more often with a LA 9-11 mm (46, 24%), rather than with an LA 6-8 mm (34, 41%). Very similar results were found between distribution per sextant, person and jaw in CPI codes 2, 3, 4 and cumulatively. In conclusion, the CPI itself is not sufficient for periodontal status assessment, especially for the 35+ years of age, and even more so for the 65+ group, and also for the CPI code 4 in all ages.
