A total of 170 adults aged 30-69 yr from the Zanzibar and Pemba Islands (Tanzania) were examined for tooth loss, dental caries and loss of periodontal attachment. The cause of tooth loss was recorded from information given by the examinee to a Kiswahili-English interpreter. Dental caries were recorded according to the depth of the lesion, i.e. involving enamel, dentin or pulp, respectively. Loss of attachment was measured as the distance in mm from the CEJ to the bottom of the pocket. The most severely affected surface determined the state of the tooth. The mean number of teeth present ranged from 29.5 in the youngest to 23.9 in the oldest age group. The mean number of teeth missing due to dental caries ranged between 2.1 and 7.0 teeth, and exceeded by far tooth loss due to periodontal breakdown which was only observed in the two oldest age groups. In all age groups the molars were the teeth most frequently missing and also the teeth most frequently affected by dental caries. Although a substantial number of the teeth in the older age groups demonstrated an extensive loss of attachment only a few teeth, mainly mandibular incisors, were lost due to periodontal breakdown within the age range examined.
