1. Assessment of the supporting tissue of the 12. In mesioangular impaction, what part of the primary bearing area is important. The clinician bone has the most reduction; should evaluate; ascending ramus soft tissue scar after alveoloplasty distobuccal bone 2. The early treatment of maxillary sinusitis is 13. The technique of labial frenectomy with wide directed towards; vestibular base; relief of breathing v incision 3. In a study conducted on dentoalveolar injuries, 14. The following are soft tissue abnormalities the most affected individuals were children aged except; 0-5 years and the prevalent etiology; labial frenum Falls 15. Early treatment of maxillary sinusitis requires 4. In the treatment of intrusion, this procedure may the use of; lead to serious pulpal and periodontal problems; nasal spray with vasoconstrictor surgical repostioning and splinting orthodintic forces 16. Characterized by episodes of sinus disease that respond initially to treatment only to return or that 5. Treatment for concussion; remain symptomatic in spite of treatment; relieve tooth from occlusion chronic maxillary sinusitis 6. In crown fractures with exposed pulp, the 17. Preprosthetic procedure uses alloplastic treatment of choice are the following except; material to recontour alveolar rideges; apicoectomy removal of buccal exostosis removal of mandibular bony undercuts 7. Displacement of tooth in mesial or distal direction, usually into missing tooth space; 18. After delivery of the impacted tooth, the cavity is lateral displacement inspected of the following except; operculum 8. Displacement of tooth into its socket usually associated with compression fracture of the socket; 19. In distoangular impaction, bone reduction is Intrusion directed towards the; ascending ramus 9. The main advantage of marsupialization is; patient is bothered by a cavity 20. The second step in the removal of impacted it is a simple procedure tooth is the reduction of overlying bone. The goal of this step is; 10. Indication for aspiration biopsy; Expose the crown lesions with fluids 21.Contraindications for impacted tooth removal 11. Indication for incisional biopsy; are the following except; small lesion patient on asa 2 category extensive lesion 22. Dentigerous cyst is categorized as; odontogenic cyst 23. Characteristic of a lesion with a suspicion of 37. The objective of recentouring alveolar ridges is malignancy; to provide this for prosthesis support while surrounding tissue is firm to touch maintaining as much bone and soft tissue as possible; 24. An example of a lesion with soft consistency; best tissue contour Lipoma 38. In the removal of a horizontal impaction, the 25. Health history is an important consideration crown is sectioned from the roots and delivered when lesions are discovered because of the from the socket. Then the roots are delivered following except; together or independently by; it is a routine procedure in dental treatment cryer elevators 26. Positive Babinski Reflex is; 39. 3 cornered flap is indicated in this case; always positive in infants class 3 position b 27. In computed tomography scan the best view to 40. Step 1 is the surgical removal of impacted tooth examine dentoalveolar fracture is; is reflecting flaps for accessibility. The ideal flap axial cut design is; envelop incision 29. Good prognosis may be achieved if the horizontal root fracture is located at; 41. In considering the size of the cyst for apical third enucleation, this may be a contraindication; risk of jaw fracture 30. Best treatment for extrusion; splinting 42. An indication of marsupialization followed by enucleation; 31. Lateral displacement of tooth can be treated by if the dentist desires to examine the lesion repositioning and splinting histologically 32. Milk is a good alternative medium for avulsed 43. In the technique of enucleation, the cyst is teeth prior to repositioning because; separated more readily from the bone cavity this it is free of bacteria pressure is maintained; Intracystic 33. In alveolar fracture, reduction may be done by; digital pressure 44. In treatment planning for preprosthetic surgery, evaluation of supporting bony tissues should 34. In replanting avulsed tooth, good prognosis will include the following except; be achieved if tooth is replanted within; auscultation 30 minutes 45. Characteristic of the best denture support; 35. Properly contoured alveolar ridges are secured adequate form and tissue coverage by closing the wound with; continuous suture 46. When removing vertical impaction, tooth is sectioned into; 36. Elevation of mucoperiosteal flap is facilitated mesial and distal with the use of; mucoperiosteal elevator 47. Factor that make odontectomy easy; 60. For patients older that 35, impacted tooth incomplete root formation removal is unfavorable because; there is decreased flexibility of bone 48. Factor that make odontectomy difficult; absence of follicular sac 61. Factors to be considered in root morphology for impacted tooth removal except; 49. The size of the follicular sac will determine the thin periodontal ligament space amount of bone removal; true 62. Compromised medical status is a contraindication for odontectomy. One of the 50. Impacted tooth is above the cervical line of the following conditions is an example; second molar with sufficient anteroposterior space; acquired coagulopathy class 1 position b 63. If pain originates from the retromolar region, the 51. Impacted third molar completely embedded in clinician should check this condition; bone with a distally oriented crown; temporomandibular joint disorder class 3 distoangular 64. An indication for odontectomy wherein removal 52. Concussion is and injury to the tooth supporting may result in the salvage of adjacent tooth by structures and is also called; cemental repair; Sensitivity - 53. Bleeding at area of the mastoid bone; 65. battle sign 66. A surgical procedure wherein the continuity 54. The most important factor in the physical between the cyst and the oral cavity is maintained assessment of a patient with dentoalveolar injuries; after evacuation of cystic contents; maintenance of patent airway decompression 55. In the examination of patients who suffered 67. In cleaving the cystic lesion from the bone, what dentoalveolar injuries, the following should be surface of the curette should always face the bone; considered except; concave lost teeth must be accounted 68. An important consideration in the examination 56. The main cause of dentoalveolar injuries in of oral lesion is its color. A bluish swelling that adults; blanches on pressure may indicate; physical assault vascular lesion 57. Studies showed that the incidence of 69. In examining ulcer base, a sign of malignancy is dentoalveolar. injuries decreased with; the presence of; age fungating wound 58. Dentalveolar injuries may result from; 70. When multiple areas of ulceration are found direct trauma to the teeth within the mouth, this procedure is done; differential diagnosis 59. Dentoalveolar injuries occur as a result of; bicycle accidents 71. In the examination of oral lesions, this indicates 87. Onset is usually described by the patient as a that the muscles of deglutition or the contents of the rapidly developing sense of pressure, pain or floor of the mouth or parapharyngeal areas are fullness in the vicinity of the affected sinus; involved; acute maxillary sinusitis dysphagia 88. Clinical examination of the maxillary sinus is 72. performed primarily by; palpation 73. 89. The volume of the maxillary sinus; 74. 15cc 75. 90. Its apex extends laterally in the zygomatic process of the maxilla; 76. maxillary antrum 77. Macroscopic accumulation of keratin; 91. The sinus is lined by; scale pseudostratified ciliated columnar epithelium 78. Large palpable mass, elevated above the 92. Midface fracture that involves the maxilla and epithelial surface; called a "floating jaw" nodule Le fort 1 79. Dried or clotted serum protein in the surface of 93.
