Summary
Vertical defects, a sign of severe periodontal destruction, were studied in dentally aware individuals. Prevalence and severity increased with age, though multiple defects remained rare.
Area of Science:
- Dentistry
- Periodontology
- Radiology
Background:
- Vertical (angular) defects signify advanced periodontal destruction.
- Understanding their prevalence and severity is crucial for dental health assessment.
Purpose of the Study:
- To investigate the prevalence and severity of vertical defects in a dentally aware population.
- To assess changes in vertical defect occurrence between 1982 and 1992.
Main Methods:
- Radiographic assessment of 251 individuals in 1982 and 247 in 1992 (ages 21-70).
- Defined vertical bone defect as > or = 2 mm one-sided interdental marginal bone resorption with angulation.
- Assessed defects adjacent to up to 28 teeth per person.
Main Results:
- Prevalence in 1982 was 38% (11% in 21-30 yrs, 64% in 51-70 yrs), decreasing to 27% in 1992 (7% to 47% in same age groups).
- Defect prevalence and severity increased with age; most had 1-2 defects, with only 5% severely affected.
- Defects were more common posteriorly and showed symmetry between left and right sides in both jaws.
Conclusions:
- Vertical defects appear relatively rare in dentally aware individuals, with multiple defects uncommon.
- Both the occurrence and severity of vertical defects demonstrate a clear increase with advancing age.
