The aim of this study was to investigate the thickness of alveolar lamina dura and
alveolar bone height by the change of periodontal status. The periapical radiograms of
the 853 cases were taken by paralleling technique.
The conclusions from this study were as follows:
1. In the normal periodontal status, the alveolar lamina dura was the thickest at
alveolar crest, followed by apex, midroot, and the average thickness of the posterior
teeth was thicker than that of the anterior teeth.
2. In Russel's Periodontal Index 0 and 1, no significant differences of thickness were
found to be 3 areas. In Russel's Periodontal Index 2 and 6, the thickness of alveolar
lamina durra at alveolar crest was decreased, only.
3. In Russel's Periodontal Index 0 and 1, distance from the cemento-enamel junction
to the alveolar crest was within 1.5mm. In Russel's Periodontal Index 2 and 6, the
distance was increased over 1.5 mm.
