Pulp space is complex, root canals may divide and rejoin. In the simplest form each root with one canal and single apical foramen is not observed always, other canal configurations are present which exit the root with two, three or more foramen. Several classifications have been proposed to describe root canal configurations for communication. With the advent of three dimensional imaging technique researchers are reporting newer configurations which cannot be classified using current system. Hence, newer classifications are proposed by each researcher. It is difficult to retain all classifications. Secondly, these newer classification are not the continuation of previous ones. Also, similar terminology has been used by different researchers for different configurations. Hence, in this paper instead of grouping root canal configurations into types, nomenclature system is proposed to identify each configuration individually.
