Description

Presented here is a case where 8 canals were located in a mandibular first molar. A patient with continuing pain in mandibular left first molar even after completion of root canal treatment was referred by a dentist. Following basic laws of the pulp chamber floor anatomy and under magnification, 8 canals were located with 3 in mesial root and 5 canals in distal root. At 1 month follow-up patient was asymptomatic .The story emphasizes how understanding the rules of pulp chamber anatomy and following them when looking for extra canals might help to avoid missing canals.
