Maxillary molar (MM) teeth often have three separate roots. These teeth may present a single-root or two-root morphology depending on the fusion between the roots, while additional roots are very rare. The reporting of this case aims to present a case of maxillary second molar with additional mesiobuccal roots in A 42-year-old female patient presented to the dental clinic complaining of pain and bad halitosis in her mouth. The patient’s medical history was obtained and revealed no significant abnormalities. Vital signs were recorded as follows: blood pressure 125/65 mmHg, heart rate 65 beats/min, body temperature 36.2 °C, and respiratory rate 18 breaths/min. Clinical examination showed that tooth #26 had an occluso-mesial restoration. A periapical X-ray of tooth #26 revealed a previously endodontically treated tooth with substandard root canal treatment. Cone beam computed tomography (CBCT) was taken for further evaluation for tooth #26, and incidentally it was found that tooth #27 had four roots. The extra root was located in the mesiobuccal area and was named an additional mesial root (MB2 root). It was separated in the middle to apical third of the mesial root. The previous case report shows a rare case of extra root in maxillary second molar, this report done to increase the awareness of such cases and to avoid complications during dental treatment.
