A 26-year-old male patient reported to the Department of Endodontics, with a chief complaint of pain in the upper right quadrant, plus unfinished restoration in the first premolar. The clinical and radiographic findings and vitality tests led to a diagnosis of asymptomatic irreversible pulpitis of the right maxillary first premolar, necessitating endodontic therapy [Table/ Fig-1a].The right maxillary first premolar was anaesthetized and isolated with rubber dam and the endodontic access was prepared. In the floor of the first premolar, only two orifices were detected. The access was modified in a cavity with a T-shaped outline and the three canals were detected. The mesiobuccal, distobuccal and the palatal canals were explored with a size 15 Flexofile (Dentsply). The working length was established with an apex locator and cleaning and shaping were performed using ProTaper Next rotary instruments (Dentsply) under abundant irrigation with 5.25% sodium hypochlorite. Final irrigation was done with 17% EDTA plus three periods of 20 seconds passive ultrasonic irrigation with sodium hypochlorite. The root canals were dried with paper points and obturated with laterally condensed gutta-percha and Sealapex sealer. (Sybron Endo) [Table/ Fig-1b]. the glide path, Protaper Next (Dentsply) files were used to shape and finish the canals under abundant irrigation of sodium hypochlorite. Calcium hydroxide was used as an intracanal medicament and after one week, obturated with cold laterally condensed guttapercha and Tubliseal sealer [Table /Fig-2b]. Case 3A 30-year-old mexican male with non-contributory medical history sought treatment, and his chief complaint was pain in the upper left back teeth region. A diagnosis of symptomatic irreversible pulpitis was made and endodontic treatment was planned in 24. Lingual and buccal canals were scouted using a 15 Flex R file. The buccal end of the access was extended mesio-distally using an Endo Z bur. A distobuccal orifice was located and working lengths were confirmed with apex locator. The canals were cleaned and shaped with Light Speed LSX Endo files and sodium hypochlorite. Canals were obturated with standardized gutta-percha points by lateral condensation technique [Table/ Fig-3a,3b].
