Five-year review of tooth mortality in a selected population in Leeds, U.K.

Abstract

The results of survey of tooth mortality, in a group of 1,507 patients attending the Conservation Department of a dental teaching hospital in Leeds, U.K., are reported. Comparisons are drawn with the results of a previous study carried out in 1964-65 and with a survey of a general population. The results suggest that there is a general tendency for tooth mortality to be lower in the present survey and this change is particularly noticeable for maxillary incisor and canine teeth. The significance of these results is discussed and various hypotheses are suggested to explain them.
