Practical #2: #14 MO preparation and #12 MOD restoration

#14 MO Preparation 

The preparation was made using a 330 bur for the outline and a 244 bur to open the box. A green FenderWedge was placed in between 13 and 14 for damage protection.
Good Features: 
Isthmus Width: CD0 condenser will just fit and CD1 will not
Proximal: Margins visually free of contact with a gingival floor depth clearance of .5mm
Pulpal Floor: Ideal 1.5-1.7mm depth
Axiopulpal line angle: Beveled

Features that need improvement: 
- Cavosurface margins: slightly rough
- Occlusal: atypical outline form
- Axial Floor Depth: slightly shallow


#12 MOD Restoration-Composite 

Good Features: 
- Occlusal Anatomy: Major grooves, pits and marginal ridges stimulate normal anatomical functions
- Margins: No flash
- Proximal Contact: No shredding of floss and proximal contour mimics anatomical shape
- Surface Finish: Smooth and shiny
- Typodont is clean

Features that Need Improvement
- Occlusal Anatomy: Slightly undercontoured and marginal ridge is not even with 11
- Margins: Slight deficiency on mesial
- Contact: Slight variation
- Proximal: Slight overhang on mesial box
