Condensing osteitis is a periapical inflammatory disease that results from a reaction to a dental related infection. This causes more bone production rather than bone destruction in the area, most commonly near the root apices of premolars and molars. The lesion appears as a radiopacity in the periapical area hence the sclerotic reaction. The sclerotic reaction results from good patient immunity and a low degree of virulence of the offending bacteria. The associated tooth may be carious or contains a large restoration, and is usually associated with a non-vital tooth. It was described by Dr. Carl Garré in 1893.
