Implication

Retrospective study reveals accelerated alveolar bone loss and tooth mortality with advancing age in adults, highlighting uneven disease progression across individuals and tooth types.

Key Points

To measure the rate of periodontal disease progression and tooth loss over a 10-year period across different age groups, individuals, and tooth types.
Randomly selected 283 patients aged 25–70 who had full-mouth radiographs taken in 1974–1976; 201 subjects (71%) returned for follow-up radiographic examination in 1985–1986.
Assessed periodontal bone height at the mesial and distal aspects of all teeth by measuring the distance from the cemento-enamel junction to the alveolar bone crest.
Mean tooth loss over 10 years was 3.8 teeth (SD 4.6), with tooth mortality increasing with age (2.9% to 28.5%), molars exhibiting the highest loss rate, and 7 individuals (3%) becoming edentulous.
Mean annual alveolar bone height reduction ranged from 0.07 to 0.14 mm in subjects aged 25–65, but reached a statistically significant higher rate of 0.28 mm per year in baseline 70-year-olds.
Approximately 75% of subjects experienced ≥0.5 mm mean bone loss and 7% lost ≥3 mm over 10 years, with 15% of participants accounting for half of all sites exhibiting severe bone loss (≥6 mm).
