Comment: Need I say anything?
Usually a "3rd canal" goes into either the mesial lingual or mesial buccal canals on a lower molar.
Occasionally, there are 3 separate canal systems in the mesial root of lower molars.
If you have properly cleaned the mesial lingual and mesial buccal canals and they are dry,
but there is exudate between the two, it usually means a 3rd canal is present.
