Abstract
Fifty mandibular second premolars were studied by a serial cross-section histologic technique. The mandibular second premolar was found to be single-rooted in all cases, but in 6% of the teeth it was seen to bifurcate or trifurcate. Several common features of furcated teeth as seen in the histologic and clinical material were noted.
Accessory canals were present in a higher incidence (66%) than reported previously by other investigators. These canals occurred most often in the apical one-third and were present as commonly in groups of four or more as they were singly. Ramifications from the main canal and calcifications in many forms were observed to further complicate the root canal system.
Age or reason for extraction did not appear to be important considerations in choosing teeth for this study. However, further research is needed to prove this before a guide for selecting teeth for the study of accessory canals can be established.
The accuracy of the histologic technique employed in this study may be responsible for the higher incidence of accessory canals reported and would suggest that investigations not using such a technique be reevaluated for other teeth in the dental arch.
