Tooth-associated lesions may be character-ized as periapical (around the apex of the tooth), interapical (between apices of two adjacent teeth), or pericoronal (around the crown of the tooth). Pericoronal lesions may arise from the ectoderm-derived components of the enamel or-gan (ameloblasts). Periapical lesions commonly Se hela listan på pocketdentistry.com • PERIAPICAL SCAR : in teeth that have been endodontically treated for granulomas and cysts and are assumed to be well sealed, a persistent, asymptomatic non enlarging radiolucency is mostly a periapical scar • Mostly occurring in the region of anterior maxilla • It is composed of dense fibrous tissue and situated at the apex of pulpless tooth. An apical scar is a small, asymptomatic, and well- circumscribed radiolucency. When observed radiographically over the years, it will either remain constant in size or diminish slightly. Fig. 7-16 Apical scar is an area at the apex of a tooth that fails to fill in with osseous tissue after endodontic treatment.

Most common at apex of 1 or more vital mandibular incisors (77%) but can form anywhere • Early stage: Entirely radiolucent • Intermediate stage: Gradual deposition of pearl-like cemental masses within radiolucency • Late stage: Uniformly radiopaque, sometimes crescent-shaped masses cupping apex of tooth • ± hypercementosis of involved tooth • Radiographically, epicenter is located approximately at the apex of a nonvital tooth. Well-defined cortication surrounds the periphery of radiolucency. Due to continuous increase in size, it often causes displacement and resorption of the roots of adjacent teeth.

Periapical and bitewing radiographs pointed to a large “unilocular” lucency in the furcation area of tooth No. 19. The lucency extended almost the entire length of the roots from the furcal aspect. Tooth No. 19 had a previous root canal treatment that the patient noted had taken place approximately 10 years prior.
