Cervical enamel projections as an etiologic factor in furcation involvement
Journal of the American Dental Association (1939)
|August 1, 1976
Summary
Cervical enamel projections (CEPs) in molars occurred in 32.6% of teeth. Severe CEPs (grades 2 and 3) were linked to periodontal furcation involvement, suggesting a potential etiologic role.
Area of Science:
- Dental Anatomy
- Periodontology
- Oral Pathology
Background:
- Cervical enamel projections (CEPs) are variations in enamel formation at the tooth's crown-root junction.
- The association between CEPs and periodontal disease, particularly furcation involvement, requires further investigation.
Purpose of the Study:
- To determine the incidence, location, and grade of CEPs in East Indian molars.
- To investigate the relationship between CEPs and furcation involvement.
Main Methods:
- Examination of 2,000 molars from 200 East Indian skulls.
- Assessment of CEP occurrence, location (buccal/lingual), and grading (1-3).
- Correlation analysis between CEP presence/grade and periodontal furcation status.
Main Results:
- CEPs were present in 32.6% of molars, with variations across tooth types (highest in mandibular second molars, 51.0%).
- Grade 1 CEPs were most common, frequently found on buccal surfaces.
- A significant positive correlation existed between Grade 2 and 3 CEPs and periodontally involved furcations.
Conclusions:
- CEPs are a common finding in molars, with specific patterns related to tooth type and location.
- Severe CEPs (grades 2 and 3) are associated with furcation involvement, suggesting they may be an etiologic factor.
- A physiological relationship between bone and CEPs is observed, with the alveolar crest adapting to CEP morphology.
