Endodontic management of dilacerated and bayonet shaped roots

Successful root canal therapy requires a thorough knowledge of root anatomy and root canal morphology which may be quiet variable. The significance of internal root canal morphology has been emphasized by studies demonstrating that variations in canal morphology may affect the endodontic outcome. Consequently, in treating each tooth the clinician must assume that complex anatomy occurs often enough to be considered normal. Root dilaceration is one of the variations that may complicate the endodontic therapy. It is important for a clinician to have complete knowledge of internal anatomy relationships, careful interpretation of radiographs; proper access preparation and a detailed exploration of the interior of the tooth to achieve a successful treatment outcome. This paper reports successful endodontic therapy of severe dilaceration of the root of mandibular first molar and bayonet shaped root of maxillary first premolar and highlights the clinical considerations to be followed during the endodontic procedures to get the successful outcome.
