If the cemental union between affected teeth is slight, the teeth may separate during extraction of one of the teeth and may never be noticed. If the union is large or firm, the planned extraction of one of the teeth may inadvertently result in the removal of its mate. A clinician’s awareness of the

The postinflammatory pattern frequently involves carious molars in which the root ends (apices) overlie the roots of impacted third molars, most common with the distally angulated third molars. The resultant large pulpal exposure often permits pulpal drainage, leading to a resolution of a portion of

The exact cause of concrescence is unknown. However, it may develop during root formation (true/primary concrescence) or after root formation (acquired/secondary concrescence). Factors that may cause concrescence include injuries (trauma), crowding of teeth, inflammation, or infection. Concrescence

Post-inflammatory concrescence must be kept in mind whenever extraction is planned for non-vital teeth with apices that overlie the roots of an adjacent tooth. Significant difficulties with extraction can be experienced during removal of a tooth that is unexpectedly joined to its neighbor.
