Relative influence of calculus and overhangs of fillings on the frequency of score 2 of the CPITN.
Periodontal treatment needs of 895 dentate subjects aged 25, 35, 50 and 65 yr were studied according to the Community Periodontal Index of Treatment Needs (CPITN). The relative influence of calculus and overhanging margins of restorations on the need for professional debridement of shallow (less than or equal to 3 mm) pockets was calculated. The mean number of sextants per person scoring CPITN Code 2 decreased from 2.6 in the 25-yr group to 1.1 in the 65-yr group. Overhangs of fillings alone were detected in 0.8 sextants of the 25-yr-olds and in 0.1 sextants of the 65-yr-olds. The mean number of sextants containing calculus with or without overhangs decreased from 1.8 in the 25-yr group to 1.0 in the 65-yr group. The relative influence of calculus was higher in the aged than in the young population. The recording of overhangs is important for accurate assessment of periodontal treatment needs in populations with a high caries experience.
