Abstract
This study covered 250 subjects aged 21–60 yr subdivided into four age groups. Oral hygiene status and dental care habits were above average and the number of teeth remaining was high in all age groups (range 24.1–27.3). All subjects were radiographically examined by means of an intraoral full mouth survey. From the radiographs periapical lesions and root fillings were recorded. A total of 117 subjects (46.8%) presented with one or more periapical lesions distributed between 294 roots (2.9%) or 229 teeth (3.5%). Two-thirds of the periapical lesions were related to endodontically treated roots. Of all endodontically treated roots 28.8% were associated with a periapical lesion. Irrespective of the relative length 17.2% of the homogeneous and 37.9% of the inhomogeneous root fillings were associated with a periapical lesion. It is concluded that periapical lesions although rare in these subjects were most frequent in root filled teeth.
