Mesial, Distal, Lingual (or Palatal), Buccal (or Facial), and Occlusal (or Incisal)
In the front of the mouth, the biting surfaces are referred to as incisal edges. In the back of the mouth, the biting surfaces are reffered to as occlusal surfaces (occlusion is a dental term for how the teeth come together).
Those surfaces would be called the Occlusal surface of the posterior teeth.
It is a Ring-shaped enlargement of the gingival margin on the vestibular surface (buccal or labial) of canines and premolars. It may be associated with occlusal trauma. DR ROBIN SRIVASTAV M.D.S (Perio)
occlusal table means the area bounded by the cusp ridges and marginal ridges
Its basically a large filling. A three surface filling can be described in example as "MOD Filling" which would the the mesial, occlusal, facial surfaces, if indeeed, that is the 3 surfaces the filling is going. Mesial and distal represent the different sides of the tooth, and occlusal is the top - center surface of the tooth. So MOD would be a filling ranging across the top of the tooth. The entire top wont be gone, but there will be a noticable filling.
In primary teeth, the ideal occlusal scheme is
1- tips of cusps 2- crests of marginal and crossing ridge 3- inclined plane of cusps and ridge 4- occlusal ,incisal,facial and lingual embrasures 5- facial or lingual surfaces (occlusal or incisal )to the height of contour except pits if present 6- axial angles of teeth
Mesial Occlusal
A lingual pit on the lingual surface of a maxillary molar is at an increased risk for cavities, due to both increased biofilm retention and thinness of enamel forming the walls of the pit. Enamel sealants are recommended to be used on the lingual surfaces of erupting teeth, although sealants have been shown to not bond as easily on lingual surfaces as they do on the occlusal surfaces.
Marinal ridge - Round, raied border on the mesial and distal portions of the lingual surfaces of the anterior teeth and the occlusal table of posterior teeth.
Class IVFound on the proximal surfaces of incisors and canines, but also will involve the incisal edge.
