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.

14. Both sides






15. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






16. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






17. Crowns tipped lingually - roots tipped laterally






18. Usually indicative of moderate to sever perio and secondary occ trauma






19. Teeth are misaligned when biting together






20. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






21. Tooth positioned more facial






22. Maxillary anterior teeth stick out labially from tongue thrusting






23. What is not affected by occ trauma






24. Mandibular molars more distal than maxillary molars






25. Above occlusal plane






26. During a left working movement - the right side is known as the






27. 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






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






29. The permanent molars erupt posterior to the primary teeth and push them all mesially






30. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






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






32. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt






33. During selective grinding - occlusion should be adjusted In what four relationships






34. Curved alignment of the occlusal plane when looking from a posterior view(right to left)






35. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip
