Sample Data
| Front | What is the endo-access shape for:Maxillary 1st Molars? |
| Back | - Triangular or Rhomboid (depends on canals + orifices)- Triangular form = in mesial border of tooth, base on buccal part and apex is lingual- Mesial border is found by line connecting 2 mesial cusps- Buccal wall is parallel to line connecting MB & DB orifice, distally reaches the oblique ridge- Pulp chamber has rhomboid shape at cervical level, with such angles:1. Acute angle = mesiobuccally2. Obtuse angle = distobuccally 3. Right angle = lingually
 |
| Front | What is the endo-access shape for:Maxillary 2nd Premolars? |
| Back | - Oval (ovoid)- Wider bucco-lingually- Narrow mesio-distally
 |
| Front | What is the shape of the endo-access cavity prep for:Maxillary Lateral incisors? |
| Back | - Oval or more Rounded triangular shape- Depends on pulp chamber prominence
