Tooth #14 MO Preparation

Tooth #14 MO Preparation - Occlusal View

Note the rough cavosurface edges on the buccal aspect of the preparation. 

Clearance of the adjacent tooth was achieved, although not adequately displayed in the picture. 

Further Considerations:
External Form
- Occlusal outline centered over central grove
- Slightly atypical outline form

Outline and Convenience Form
- Margins are visually free of contact with tooth at buccal and lingual
- Gingival floor depth - clearance of 0.5 mm on gingival margin to adjacent tooh

Resistance Form
- Slightly acute or obtuse cavosurface margins

Refinement
- Cavosurface margins and walls of preparation are slightly rough or unfinished

Operative Environment
- No rubber dam remaining, operative field appears clean.
