Abstract

Aim. To report a case of maxillary second premolar with four roots and four separate foramina and the use of CBCT to help identify the root canal system configuration. Summary. A 45-year-old female patient with a no significant medical history was referred for treatment tooth #15. The tooth was diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis.

Root canals treatment was carried without complication under dental operating microscope using a rotary system and continuous wave obturation.
