1. which of the following bacteria do not invade host tissue cell F.Nucleatum P.gingivalis P.intermedia T.denticola 2. Not a part of RED complex: Actinomycetemcomitans P denticola P gingivalis P forsythus 3. In horizontal alveolar bone loss, the pathway of inflammation is perivascularly, into the marrow spaces of the crestal bone through the epithelial attachment. through the cortical bone of the alveolar process. through the periodontal ligament. 4. Bacteria associated with Acute Necrotizing Ulcerative Gingivitis (ANUG): Leptospira Porphyromonas Prevotella Neisseria 5. Which interleukin (IL) is important in the acti- vation of osteoclasts and the stimulation of bone loss seen in periodontal disease? IL-1 IL-10 IL-2 IL-8 6. Which of the following organisms is not implicated in the etiology of periodontal diseases Neisseria Eikenella Bacteroides Wolinella 7. Apical migration of the epithelial attachment with corresponding recession of the marginal gingiva results in Gingival pocket formation Infrabony pocket formation Periodontal pocket formation A shallow sulcus 8. The specific plaque hypothesis was delineated by: Walter Loeshe Sigmund Socransky Robert Koch Schroeder HE 9. Modes of attachment of calculus to the tooth surface include all of the following, EXCEPT Mechanical locking into surface irregularities Close adaptation to unaltered cementum Penetration of calculus bacteria into cementum Attachment by means of an inorganic pellicle 10. which of the following is true in case of AIDS patients acute pain diffuse red lesion of the attached gingiva gingival itching gingiva covered with pseudomembrane 11. Mechanisms involved in enamel pellicle formation include all of the following, EXCEPT: Electrostatic mechanisms Van der Waals forces Hydrophilic forces Hydrophobic forces 12. In GCF, ratio ofT:B Lymphocytes is: 3 isto 1 1 isto 2 2 isto 1 1 isto 3 13. purulent exudation from the gingival sulci is an indication of shallow pocket severe periodontal attachment loss deep pockets nature of the inflammatory changes in the pocket wall 14. The following periodontal fibres are most resistant to periodontits Transgingival Intergingival Transseptal Circular 15. Diabetic patient with periodontitis have significantly higher level of ______________ in GCF All PGE2 TNF Interleukin-1 16. Corncob formations in plaque have been observed between.- Rods Cocci None of the above Rods and cocci 17. blood supply of the buccal marginal gingiva is through the supraperiosteal vessels transalveolar vessels subperiosteal vessels branches of internal carotid artery 18. Periodontitis can be associated with all of the following except: Attachment and bone loss that is not progressing Bleeding upon probing Elevated sulcular temperature Increased gingival exudates 19. PMA index is used to record the status of: Periodontal disease Carious teeth Gingival disease Root caries 20. which radiographic technique gives three dimensional view of the alveolar bony defects orthopantamograph intra oral radiograph digital intraoral radiograph spiral computed tomography Loading … Question 1 of 20
