Canal Orifice: In the mandibular first premolar teeth one canal orifice was found in 1teeth (8) and two canal orifices were found in teeth (1) The shape of the canal orifice was found to be round in teeth (3), oval in teeth (5) and flattened ribbion in teeth (1) ( Table ). Root canal anatomy increases in complexity as you go distal from the midline. Multiple roots and canals occur with increasing frequency in posterior teeth. Looking For Lower Premolar ? We Have Almost Everything On eBay. Certain types of teeth ( lower incisors, upper premolars, molars) and even specific tooth roots (mesiobuccal roots of upper first molars, distal roots of lower 1st molars) are well known for having the potential to have additional canals.
