An objective method of assessing the periodontal condition in human skulls

An objective method is described for estimating the periodontal state of human skulls. Two measurements were made for each tooth from the alveolar crest to the amelo‐cemental junction and, from the average of these for the whole mouth, an estimate was calculated called the Tooth Cervical Height‐Index. It was found possible to repeat measurements with a considerable degree of precision. When forty skulls with varying degrees of periodontal disease were examined a significant correlation was recorded between the T.C.H.‐index and the periodontal state as estimated using clinical criteria (after Russell).
