Clinical features of Chronic Apical Periodontitis
Common features of Chronic Apical Periodontitis are :
- Chronic periodontitis is a low-grade infection. It may follow an acute infection that has been inadequately drained and incompletely resolved.
- The tooth is non-vital and may be slightly tender to percussion but otherwise symptoms may be minimal.
- Frequently, chronic periodontitis is first recognised as a rounded area of radiolucency at the apex of a tooth (an ‘apical granuloma’) in a routine radiograph .
- The area is usually about 5 mm in diameter and has well-defined margins.
A distinct cortex is sometimes interpreted as early cyst formation, but this cannot be confirmed without a biopsy.
Possible complications of chronic apical periodontitis
- Periapical granuloma formation
- Radicular cyst formation
- Suppuration and sinus formation
- Acute exacerbations
