Root caries among Benghazi patients.

A total of 420 Benghazi patients were clinically examined for root caries. Root caries was not limited to older patients and the proportion of root caries among young adults was similar to that of the older age groups. Most of the lesions were located proximally and underneath restorations rather than labially or lingually. Our results may serve as baseline data for further studies on root caries in the Libyan Arab Jamahiriya.
