The purpose of the present study was to estimate the lost attachment surface area (LAS) and the remaining attachment surface area (RAS) of molars from a combination of clinical and radiographic measurements. Clinical and radiographic measurements on 32 maxillary and 26 mandibular molars were correlated with the post‐extraction measurements of LAS and RAS. The results indicate that linear models may increase the precision of the estimate of LAS by a factor of 1.2 for maxillary molars and 1.4 for mandibular molars when compared to estimates of LAS using only attachment level measurements. A diagnostic model for RAS predicts the square root of the remaining attachment surface area with the information obtained from the remaining radiographic attachment area and a gingivitis index. It is concluded that modeling of periodontal data may provide a method for predicting lost and remaining periodontal attachment area of molar teeth.
