  2. What are tooth dilacerations • a developmental problem which involves the malformation of a tooth either at the crown or root portion. • This results in a tooth having sharply angulated roots. • * Also common to have crown dilacerations but root dilacerations are more common.

  3. Cause of tooth dilacerations • Distortion of HERS ( Hertwig’s epithelial root sheath) due to an injury or pressure. • HERS = membrane that shapes the root(s) by inducing dentin formation in the root area so that it is continuous with the coronal dentin. • Can occur in any group of teeth during tooth development.

  4. complications • Bend in root is so pronounced that teeth may fail to erupt. • cause problems during extraction and endodontic therapy.

  5. How to prevent tooth dilacerations • Hard to avoid because accidents may happen at any time • * Do NOT replace baby teeth if they are knocked out. Replaced tooth may disturb permanent teeth from growing in or bacteria may infest the socket.

  6. Treatment/Role of the dental team • Surgical extraction or repositioning • Root canals • * In case root canal or extraction is needed, the patient should be referred out to see an oral surgeon. • These treatments are a common practice but commits the patient to extensive future restorative care.
