Mandibular Cuspid

Mandibular cuspids usually have only one root but in rare cases may have two separate roots. Teeth with one root may have Type I, II or III configuration. These teeth are usually the longest of the mandibular teeth but have greater length variation than do maxillary cuspids. The root canal is thin mesio-distally but wide labio-lingually. The cervical cross section is oval and so is the endodontic access cavity outline. This tooth usually has a slightly labial axial inclination of the crown. Therefore, the access is directed towards the lingual surface. However, always remember that if in case two canals are present, an access preparation that is wider bucco-lingually should be used.
