Abstract: 

The aim of this case report is to present an unusual maxillary first molar with a single root and a single canal. The significance of this case is that, according to most endodontics and dental anatomy textbooks, the human maxillary first molar usually has three roots and three or four canals. Based on our literature search, this case report is the second reported maxillary first molar with single root in the world and the first in Iran. A 42 years old lady with acute pulpits of the left maxillary first molar was referred to our clinic. The probability of the presence of single root and single canal of the first molar was considered based on her panoramic view. Access opening revealed a single wide canal orifice extending from buccal to lingual side. The presence of a single root and canal was proved by preparing several periapical radiographs with different horizontal angulations during root canal therapy.
