Evaginations

Evaginations are morphological anomalies where the pulp has made an extension towards the tooth surface. Dentine and enamel follow the pulpal extension which may be seen as an extra cusp or enamel pearl on the tooth surface. Evaginations are rare, and are usually seen in lower premolars. They typically cause occlusal interference. If eliminated by grinding in one appointment, pulpal exposure and damage will follow. Gradual grinding of 0.1 mm per month before occlusal contact is established may help to avoid pulpal inflammation.
