A radiographic survey of periodontal conditions in Greece.
The present study used radiographic assessments to evaluate the pattern of destructive periodontal disease ina rural and an urban sample of 25-64 year old Greek adults. The rural sample (A) comprised 190 subjects and the urban sample (B) 400 subjects. 13% of the subjects in sample A and 8% in sample B were edentulous. Full-mouth intraoral radiographs were obtained from the 503 dentate subjects and were examined with respect to (i) number and type of teeth present, and (ii) alveolar bone level (ABL), i.e., the distance between the cementoenamel junction and the alveolar bone crest at the approximal tooth surfaces. The results revealed that alveolar bone loss was ubiquitous in both samples. Pronounced bone loss, however, (i.e., a subject mean ABL of > or = 6 mm) affected 18% (sample A) and 8% (sample B) of the individuals. Although an ABL of > or = 6 mm was scored at 7.2 sites/subject in sample A and at 4.5 sites/subject in sample B, more than 10 such sites were found in 23% (A) and 11% (B) of the examined subjects. 25% of the subjects in the rural sample (A) and 12% in the urban sample (B) accounted for 75% of the total number of tooth sites with pronounced bone loss. Multiple regression revealed that age and number of remaining teeth were the parameters most strongly correlated with the amount of bone loss on both the individual subject and the tooth site level. The present findings (i) demonstrated a high prevalence and severity of destructive periodontal disease in these 2 samples. and (ii) confirmed the skewed distribution of advanced disease in the population.
