Canal configuration in the mesio-buccal root of maxillary first molar teeth of a Jordanian population.
The purpose of this study was to investigate the canal configuration in the mesio-buccal root of maxillary first molar teeth of a Jordanian population using a clearing technique. One hundred extracted maxillary first molars were collected from Jordanian patients. After a standard access preparation, canals were stained, decalcified, dehydrated, and then rendered clear. The prevalence of a second canal in the mesio-buccal root was 77.32%. Types IV and II canal systems were the most common types with prevalence of 35.05% and 27.83%, respectively. Additionally, 28.86% showed lateral canals mostly located in the apical third and 37.11% had intercanal communications, mainly in the middle third of the root. It was concluded that the prevalence of mesio-palatal canals was high and Types IV and II canal systems were the most prevalent.
