Hi doctors, was just wondering what is an mo and an ml in dentistry work?

Surfaces: There are different surfaces on the teeth: mesial, occlusal, lingual, buccal, distal. The letters describe the surfaces where the filling was placed.

Dental Anatomy: MO = Mesio-occlusal, and ML = Mesio-lingual is terminology referring to the surfaces of the teeth.

Descriptions: Excellent question.Both refer to restorations(fillings) that involve two surfaces of the tooth.An MO involves the mesial and occlusal surfaces of a back tooth.That is the chewing surface(occlusal) and the in between surface closest to the tooth in front of it.An ML is a mesial lingual restoration on a front tooth which involves the tongue side(lingual) and the in between side closest to the middle
