Aim: The aim of this study was to assess the periodontal condition of a group of 35-44 years old patients from the Iasi region
of Romania using the CPITN index and to see if there were any correlations with the income level of the patients assessed.
Method: A cross-sectional study was conducted in dental clinics in rural and urban areas of Iasi in 2006-2007 and a sample
of 928 people (age 35-44 years old) was examined according to the CPITN index criteria by two calibrated examiners.
Their income level was then assessed as high, medium or low. Data were analyzed using the SPSS statistical program package.
The Spearman correlation was used to compare the differences in prevalence and the correlation between CPITN
scores and income. The study was approved by the Department of the Trust who gave ethical approval. Results: Of the 928
patients 311 (43.5%) were in the highest income level group, 437 (47%) were in the middle income group and 180 (19.5%)
were in the lowest income group. Only 84 patients (9.1%) were assessed as CPITN 0. Afurther 201 (21.7%) were assessed
as having a CPITN score of 1. The majority (504 Â– 54%) were assessed as CPITN 2 and 141 (15.2%) as CPITN 3 or 4 (having
a pocket or pockets of 3.5mm or deeper). Only 24 patients (2.4%) had a pocket or pockets of 5.5mm or deeper (CPITN
4). None of these 24 patients came from the group with the highest income. When statistically tested, the Spearman correlation
confirmed an association between the presence of a pocket or pockets deeper than 3.5mm and income level (r=-0.3,
p=0.001). Conclusions: In Iasi county, in the 35-44 year-olds who were studied, the majority had a CPITN score of 2. Just
over 15% had a pocket or pockets deeper than 3.5mm and only 2.5% had a pocket or pockets deeper than 5.5 mm. Income
level was a risk factor which correlated with the presence of periodontal pockets.
