Radiographic quantification of alveolar bone level changes: Predictors of longitudinal bone loss

Abstract

The purpose of the present study was to determine the relative importance of a set of predictors for the radiographic change in alveolar bone level over 2 years in a group of 180 subjects and to assess the fit of the applied multivariate model. The included predictors were age, sex, initial bone level, type of initial lesion, tooth type, proximal tooth surface, calculus, and the presence of metal crowns or proximal fillings. The multivariate method of choice was multiple classification analysis. The results indicated that in descending order tooth type, initial bone level, and age were the most important predictors. Sex, calculus, and crown and filling margins also showed significant direct effects (beta) on longitudinal bone loss (p less than 0.05). However, their relative importance was far less than that of tooth type, initial bone level, and age. Proximal side showed no significant direct effect. Using seven predictors, the applied multivariate model explained 20% of the variance in longitudinal bone loss.

Disease progression in periodontally treated and untreated patients – a retrospective study

“…Group average values. The annual loss rate of 0.07 mm bone height in group A is somewhat lower than the rates given in the literature: Lavstedt et al (1986) reported a progression ol 0.16 mm/year in 38-year-old periodontally untreated subjects; Papapanou et al ( 1989) and Albandar et al ( 1987) found over 0.15 mm and 0.16 mm, respectively, in 50year-olds. The statistically significantly higher bone loss among patients who discontinued treatment suggests the conclusion that, as a rule, systematic periodontal treatment with regular followup care protects compliant patients from further progression of the periodontal destruction.…”

Utility of radiographic crestal lamina dura for predicting periodontitis disease‐activity

“…However, radiographs for periodontal disease assessment often only confirm information obtained from clinical evaluations of probing depth and clinical attachment level (Goodson et al 1984). Radiographic analysis of angular bony defects (Pontoriero et al 1988, Heins et al 1989, Steffensen & Weber 1989, Papapanou & Wennstrom 1991, alveolar bone height (Albandar et al 1987) or interdental bone width (Heins et al 1990) generally provides limited or no insight into the future status of the periodontium, similar to most clinical periodontal parameters (Haffajee et al 1983, Halazonetis et al 1989, Badersten et al 1990, Vanooteghem et al 1990 or narrowly-based microbiological assays (Wennstrom et al 1987, Slots et al 1988, Listgarten et al 1991. In order to expand the diagnostic yield of conventional dental radiographs, the predictive capability of radiographic crestal lamina dura for detecting periodontal breakdown was tested.…”

Validity and reliability of alveolar bone level measurements made on dry skulls

“…However, the long debated issues of validity and reliability of this method are yet unsolved (Listgarten 1980, Badersten et al 1984, Watts 1987. On the other hand, radiographic methods have been used for similar purposes (Selikowitz et al 1981, Rohner et al 1983, Albandar et al 1986, 1987, and different techniques have been proposed to improve the reproducibility of intraoral radiographs (Eggen 1969, Renggli et ai. 1971, Rosling et al 1975.…”
