Etiology • A mass of inflamed granulation tissue • Forms secondary to pulp necrosis of the associated tooth • May develop following periapical abscess formation or may
form as pulpal death eventuates without abscess precursor
Clinical Presentation • Usually asymptomatic • With acute exacerbation, pain and sensitivity develop. • Tenderness at root apex on palpation • Pain on biting or percussion of tooth
Radiographic Findings • Radiolucency at apex of tooth • Size ranges up to 1 to 2 cm in diameter • Root resorption not uncommon
Diagnosis • Radiographic features • Demonstration of nonvital pulpal component

Radiographic Findings • Radiolucency at apex of tooth • Size ranges up to 1 to 2 cm in diameter • Root resorption not uncommon
Diagnosis • Radiographic features • Demonstration of nonvital pulpal component
Differential Diagnosis • Periapical cemental dysplasia • Periapical cyst
Treatment • Conventional endodontic therapy • Apical curettage/root end amputation if above measures fail • Extraction of involved tooth
Prognosis • Excellent
