Marginal alveolar bone height in an adult Swedish population

Abstract

The purpose of the present cross-sectional epidemiologic study was to assess the interproximal alveolar bone level within the dentition of 732 randomly selected adult individuals, stratified according to gender and age. Full mouth series of periapical radiographs were used for the assessments of the relation alveolar bone height/root length (B/R). A computer/digitizer recording method was utilized for the assessments. The results were presented as (i) mean values per age group and gender, (ii) mean frequency of subjects with sites exceeding certain thresholds of bone loss and (iii) cumulative frequencies of subjects with various number and percentual proportion of sites in relation to different B/R-ratio intervals. The results showed a reduction in mean alveolar bone/root ratio with age. The women had a significantly more favourable mean B/R-ratio than men in the ages above 40 years; the women had, however, more missing sites above age 60 years. By older age, there was observed an increased variation between individual mean B/R-ratios. Only a few subjects had a mean B/R-ratio less than or equal to 50%. A subfraction of the subjects in the different age groups had greater than 20% of their sites below a B/R-ratio of 60%. This fraction increased with age.

“…of age in the present comparison group (Table 3) did not seem incompatible with that of Salonen et al (21). Furthermore, both prevalences are within the boundaries of worldwide estimates for periodontal highrisk groups.…”

“…The coronal level of the tooth-supporting tissues is usually situated at some distance from the CEJ (9, but there is no generally accepted standard against which to estimate (2,21). In the study by Salonen et al (21) the bone level was considered to be intact when 80% or more of the root was supported by bone.…”

Validity and limitations of self‐reported periodontal health

“…The differences in the cut-off points are based on the knowledge that periodontitis increases with age (24,25) and therefore a higher cut-off point was chosen for the oldest group. In order to do a cross-tabulation; the material was divided into one group with severe gingival inflammation and one with mild.…”

Maxillofacial cone beam computed tomography (CBCT) : aspetcs on optimisation

“…Diagnostic information on the marginal bone level has usually been obtained from 2D radiography (periapical and/or panoramic) (Björn et al, 1969;Albandar et al, 1985;Salonen et al, 1991). However, there are shortcomings associated with these 2D imaging methods even when efforts are made to obtain periodically identical radiographs or to compensate for image distortions.…”
