Summary
The most common peri-radicular lesions of the jaws are inflammatory lesions caused by infection of the dental pulp. Peri-apical granuloma, chronic peri-apical abscess, peri-apical pocket cysts, radicular cysts, extra-radicular infections, foreign body reactions and fibrous scar tissue typically present as unilocular peri-apical radiolucencies of varying size and degrees of circumscription. The need to differentiate can only be based on a careful history taking, clinical signs and symptoms and equivocal pulpal sensibility testing followed by commencement of nonsurgical root canal treatment to tip the balance in favour of healing.
