Abstract
The aim of this study was to determine the frequency, distribution and extent of dental caries and tooth wear in a Byzantine population in Sa'ad, to compare these with modern Jordanians, and to draw inferences about their lifestyle. Dental caries and tooth wear were examined in 1159 permanent teeth using direct vision and dental explorer. The location and extent of the lesions were recorded and evaluated according to defined criteria. The overall caries prevalence was 16.8% (nโ=โ1159). Most of the carious lesions (13. 9%, nโ=โ1159) were present in the tooth crown, on occlusal or proximal surfaces; 2.9% of teeth displayed root caries alone. The upper and lower central incisors exhibited the lowest coronal caries frequency, while molars showed the highest frequency. Attrition with moderate dentine exposure was evident in most teeth. Some teeth (9.8%) demonstrated oblique abrasion and 9 (0.78%) teeth exhibited cupped occlusal surfaces. The prevalence of caries was within the range reported for other Byzantine populations and lower than that of modern Jordanians. The attrition seen in most teeth and the cupped occlusal surfaces might be due to eating abrasive food, drinking wine or acidic beverages. Oblique abrasion on the facial and palatal surfaces reflects their business or craft, such as basket making and leather processing. Copyright ยฉ 2008 John Wiley & Sons, Ltd.
