Flow chart in next column representing the pathogenesis.

Periapical Granuloma Clinical Features

• Tooth is often asymptomatic.
• Previous history of prolonged sensitivity to heat or cold.
• Deep caries, a deep restoration or history of trauma.
• Tooth is often tender to percussion.
• Fail to react to thermal or electrical stimulation (because the pulp is nonvital).

Periapical Granuloma Radiographic Features

• Earliest sign: Thickened PDL space at the root apex
• Well-circumscribed radiolucency: Somewhat rounded and surrounding the apex of the tooth

Clinical Features of Periapical Granuloma

• Thin radiopaque hyperostotic border.

Radiographic Features Of Periapical Radiolucencies

Periapical Granuloma Microscopic Features

• Proliferating endothelialcells, capillaries, young firoblasts, collagen, chronic inflammatory cells, lymphocytes, plasma cells, macrophages.
• Nests of odontogenic epithelium, Russell bodies, foam cells, cholesterol cleft.

Periapical Granuloma Treatment

• Extraction of the involved tooth.
