Canal configuration of the mesiobuccal root of the maxillary first molar. Study in senegalese population. - ROS - 2006 - Tome 35 - N°3

Objectives: The aim of this study was to determine the percentage of anatomical canal configuration of the mesiobuccal root (MBR) of the maxillary first molars from Senegalese patients.
Methodology: one hundred and fourteen teeth were obtained from general dentists who knew absolutely that they were extracted from Senegalese patients. After standard access preparation, distobuccal and palatal roots were removed for radiographic convenience. Preoperative radiographs were taken of the remaining crown and mesiobuccal root (MBR) from mesiodistal and buccopalatal directions for each tooth. Canal orifices of MBR were located and explored with size 08 files to the apical foramen. In 104 teeth, all MBR canals were negotiable to the apex and enlarged up to size 15 file. If another canal opening was found at the apex, a file was inserted into and passed coronally. For each tooth, mesio-distal and bucco-palatal angle radiographs were taken with the files in place.
Results: According to Weine's classification, 46.2% of the teeth had been found of type I, 31.7% of type II, 19.2% of type III and 2.9% of type IV.
Conclusions: The prevalence of two canals in the mesio-buccal root of maxillary first molar from Senegalese patients was similar to that found in other ethnic population.
