Case: DT06
A Patient came to for Root Canal treatment, 2nd lower premolar to be precise. So logically the anatomy of the lower 2nd premolar is as following:
[quote align=”center” color=”#999999″] Investigators reported that only 12% of mandibular second molars studied had a second or third canal. Vertucci also showed that the second premolar had one canal at the apex in 97.5% and two canals at the apex in only 2.5% of the teeth studied.[/quote]
