Tooth mortality in different age groups in Alexandria province

ABSTRACT

The tooth mortality of 400 Egyptian persons aged 15 years and older was studied in terms of missing teeth as well as teeth requiring extraction. The mean number of missing teeth per person was 7.1. A pattern relating actual tooth loss and tooth loss adjusted to take account of teeth needing extraction was observed. Such adjustment increased the mean number of missing teeth per person by about one or two teeth and this difference was constant over the various age groups excepting the oldest category, the mean missing teeth per person increased by about four teeth. The age specific pattern of tooth loss was calculated. The age specific tooth mortality for Egyptian group was consistently less than for people in several western countries
