Abstract
Background: There is paucity of literature on the determination of the root canal length of Bantu subjects in dental professional practicing in Africa and Democratic Republic of Congo in particular. Aims: The aim of the present study was to determine the root canal length of teeth of Bantu patients extracts attending the Teaching Hospital of Kinshasa University. Methods and Material: Prospective cross-sectional study was carried out in the service of Conservative Dentistry. The patients suffering with pulpitis of permanent teeth which were selected for root canal treatment during the period of January 2014 to December 2016 were included. All patients whose main root canals were inaccessible, teeth carrying prosthesis, teeth with large coronal decay, teeth having periapical periodontitis, supernumerary teeth, wisdom and primary teeth were excluded. Results: The upper canines presented some significant longer canals compared to the lower canine (23.4 ± 2.3 mm and 21.6 ± 1.8 mm). Palatal canals of the first and second molar were respectively longer as compared to the superior teeth canals (21.5 ± 1 mm, 21.3 ± 2 mm). The distal canals of the first and second molar were the longest in the mandibular arch respectively measuring 20.7 ± 2.0 mm and 21.5 ± 1.7 mm. Conclusion: Data obtained from Bantu patients show slightly shorter roots compared to some European populations, but longer than some Asian populations.

This study was carried out to determine the root canal length of people of Bantu origin consulting in the Teaching Hospital of Kinshasa University
The upper canines are anterior teeth having a large root canal length followed by upper central incisors with 23.4 ± 2.3 mm and 21.8 ± 1.6 mm’ instead respectively (Table 2)
Summary
Endodontics is the discipline regarding prevention, diagnosis and treatment of diseases of the pulp and periapical area. The majority of studies in literature has been reported estimation of root canal length mentioned in the subjects of Caucasian origin [3] [4] [5] [6] or Asian origin which stated by an anthropologist that taller individual generally has longer teeth than shorter individuals and later studies concluded that the teeth of Caucasians are longer than these of Asians population. These values are presently regarded as reference standards.
