title: A study of the dental pulp cavity of mandibular first permanent molars in the Kuwaiti population.
abstract: This study documented the complexity of the root canal system in the mandibular first permanent molar. Forty-nine plastic replicas were used from mandibular first permanent molars obtained from young Kuwaitis. Results revealed that the tooth had 2 canals, 3 canals, and 4 canals 6.1%, 67.4%, and 26.5% of the time, respectively. The number, distribution, and apical exit of the canals were compared with the results of previous related reports. Several recommendations were given to aid in the diagnosis and treatment of extra root canals.
