Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Vibrational mvmt of a tooth under occ function






2. Posterior; no horizontal overlap






3. ____ is not a sign of occl trauma






4. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






5. Horizontal distance of anterior teeth in crossbite






6. Contact between maxillary incisors does not line up with contact of mandibular incisors






7. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






8. Anterior or posterior; bilateral or unitlateral - anterior more common






9. Mesially - Labially






10. Radiographically - the PDL space is wider at the coronal third of the root






11. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






12. Maxillary - Mandibular - Facial






13. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






14. When no teeth are contacting on this side






15. Maximal intercuspation or contact of the max and mand teeth






16. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






17. Relationship of the teeth in opposite arches; static position






18. Prognathic profile






19. Mandibular molars more distal than maxillary molars






20. Starts around the mesial of the 1st molar






21. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






22. Above occlusal plane






23. Guidance for protrusive occ should be on the






24. Buck teeth are common and are considered






25. Tongue thrusting; thumb sucking - pacifiers






26. What is not affected by occ trauma






27. Teeth are misaligned when biting together






28. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






29. #10 & #23






30. Widening of the PDL in areas under pressure results due to






31. Malposition - crowded anterior teeth - protruded or retruded max incisors - anterior/posterior crossbite - mesial drift






32. Functional occlusion






33. Abnormal contacts; occlusal habits - and neuroses






34. During protrusive occ - ______ is considered undesirable






35. Maximum interlocking of cusp






36. Primary teeth set ___________________ for permanent






37. Curved alignment of the occlusal plane when looking from a lateral view(distal to mesial)






38. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






39. II (mal)occlusion






40. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






41. Starts closer to the posterior of the 1st molar






42. Maximum touching of max and mand






43. Vertical






44. Relationship of the arches bone to bone;






45. Tooth extracted






46. Excessive deposition of cementum around the apex - due to excessive occlusal forces






47. The way you normally bite your teeth together when not chewing






48. Crowns tipped lingually - roots tipped laterally






49. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






50. Mb cusp of max 1st molar-buccal groove of mand 1st molar
