| Question | Answer |
|---|---|
| TRUE OR FLASE: BPA is found in some composites and has not been proven to have any health side effects when its cured. | TRUE |
| Why does a composite restoration require incremental filling? To allow for precise placement So the restoration doesn't get wet To allow the patient to relax To help eliminate composite shrinkage | To help eliminate composite shrinkage |
| TRUE OR FALSE: When using a traditional composite material a large composite restoration does not need to be incrementally filled. | FALSE |
| TRUE OR FALSE: Hybrid composites are considered the standard composition for composites due to their polish-ability, abrasion resistance, and strength. | TRUE |
| How can the oxygen inhibited layer be removed from a newly cured composite restoration? It doesn't need to be removed Wiping with 2x2 Pumice slurry It will wear off within 24 hours | Pumice slurry |
| The following are all associated with macrofill composites possess EXCEPT: Weak Abrasion resistant Large filler particles Poor esthetics | Weak |
| TRUE OR FALSE: Coefficient of thermal expansion is the lack of expansion by the restorative material? | FALSE |
| What are two substances that make up composites? Filler particles and BIS-GMA Matix and macrofill particles Nanofilled particles and a coupling agent Filler particles and its matrix | Filler particles and its matrix |
| Percolation is ___________________. A result of a high coefficent of thermal expansion A result of poor composite placement due to composite having BIS-GMA in it An effect of polishing | A result of a high coefficent of thermal expansion |
| Maxilary molars have have how many occlusal pits? 4 2 3 5 | 3 |
| How many roots do most maxillary molars have? 4 3 2 1 | 3 |
| What is NOT an example a complication due to pin placement? Perferating the outside wall of the tooth Better filling retention Poor pin placement resulting in pulp trauma (ie root canal) | Better filling retention |
| TRUE OR FLASE: Light cure and self cure are examples of composite polimerization. | TRUE |
| _____ is thought to be the standard depth that a curing light can cure composite. 3mm 1mm 4mm 2mm | 2mm |
| TRUE OR FLASE: Hydrophobic materials hates water and hydrophilic materials loves water. | TRUE |
| Functional Occlusion is: How teeth contact during normal chewing and swallowing How an individual bites when their tongue is to the roof of their mouth Is created my a dentist performing an occlusal adjustment Is different for everyone | How teeth contact during normal chewing and swallowing |
| TRUE OR FALSE: When checking occlusion, protrusive movements the mandible should not jut forward farther than the alignment of the upper and lower incisal edges (edge to edge). | TRUE |
| TRUE OR FALSE: When checking occlusion, lateral excursive movements the mandible should not move forward farther from side to side then the alignment of the upper and lower canine cusp tips | TRUE |
| TRUE OR FALSE: When checking occlusion, a donut shaped mark on natural tooth would be unacceptable if it were located on a new restoration, or at the margin of a new restoration (half on tooth half on filling). | TRUE |
| What is the correct order when checking occlusion? Identify high marks, reduce, dry, repeat Reduce, dry, identify high marks, repeat Dry, reduce high marks, repeat, identify high marks Dry, reduce, identify high marks, repeat | Dry, reduce, identify high marks, repeat |
