Abstract

The aim of the present study was to assess the cumulative radiographic alveolar bone loss (CRABL) and yearly radiographic periodontal attachment loss (YRABL) of periodontal disease groups over 5 years or more. A total of 53 subjects, who had taken two sets of full-mouth standardized paralleling radiographs with separated periods of 5 years or more in Kaohsiung Medical University Hospital during 1981-2001, were collected for the past 20 years.


The radiographic alveolar bone levels at mesial and distal aspects of teeth were assessed by measuring the distance between cemento-enamel junction and alveolar bone crest using an electronic digimatic caliper (EDC) under a 3.5X magnified radiographs.


The results revealed that 1) patients with a periodic recall (3-4 times/yr.) showed a significantly lower loss rate than patients without periodic recalls; 2) mean CRPAL was highest in the generalized aggressive periodontitis (GAgP) group (5.52±3.27mm), then the chronic periodontitis (CP) group (4.82±3.47mm), and the localized aggressive periodontitis (LAgP) group (4.47±3.47mm) followed, and lowest in the periodontal healthy (PH) group (1.05±0.59mm); 3) mean YRPAL was the highest in the LAgP group (0.26±0.25mm/yr.), then the GAgP group (0.20±0.13 mm/yr.), and the CP group (0.12±0.09 mm/yr.) followed, and lowest in the periodontal healthy group (0.07±0.06 mm/yr.).


It was concluded that: 1) sites with more advanced alveolar bone loss are more likely to undergo further breakdown; 2) patients with a periodic recall showed a significantly lower alveolar bone loss rate and bone gain, irrespective disease groups; 3) mean CPBLs was highest in the GAgP group; mean YRABLs was highest in the LAgP.
