RAD TCDHA FINAL EXAM NEWEST 2024 ACTUAL EXAM 100 QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS) |ALREADY GRADED A biologic width - answer-space on the tooth surface occupied by the junctional epithelium and the connective tissue fibers a mature plaque biofilm - answer-is more pathogenic than the biofilm that first developed on the tooth surface: - types of bacteria in biofilm change as biofilm matures. plaque maturation - answer-plaque biofilm allowed to grow undisturbed= mature as it matures- colonized with gram negative periodontal pathogens Effects of Food Impaction - answer-Can strip gingival tissues away from the tooth surface. Can lead to alterations in gingival contour =interdental areas difficult for patients to clean. trauma from occlusion - answer-excessive occlusal forces that cause damage to peridontium signs of trauma from occlusion - answer-Tooth mobility Sensitivity to pressure Migration of teeth Enlarged, funnel-shaped PDL space Alveolar bone resorption Parafunctional Occlusal Forces - answer-Can exert excessive force on the teeth and to the periodontium -result from tooth- to-tooth contact when not in the act of eating therapy- occlusal adjustment/ night guards Functional occlusal forces - answer-normal forces produced during the act of chewing food Primary occlusal trauma - answer-injury to the sound periodontium (with no previous history of periodontal breakdown) from excessive occlusal forces - High restorations. - Excessive force on abutment teeth from partial dentures. - Changes: wider PDL, tooth mobility,pain. - Changes are reversible if trauma is removed Lateral Occlusal Forces: Primary Trauma - answer-Tipping of the tooth within the socket due to lateral occlusal forces: Secondary occlusal trauma - answer-injury to the periodontium that was previously damaged by periodontitis from normal/excessive occlusal forces may result in rapid bone loss/ pocket formation Clinical Periodontal Assessment - answer-a fact-gathering process to provide a picture of the patient's periodontal health status. info gathered forms: -Periodontal diagnosis - Individualized treatment plan Periodontal Screening Examination - answer-quick process to determine if a more comprehensive assessment is needed Comprehensive Periodontal Assessment - answer-intensive and in-depth information-gathering process Components of the Periodontal Assessment - answer-Gingival inflammation • Level of free gingival margin • Recession of the gingiva • Level of mucogingival junction • Probing depth measurements • Bleeding on probing • Presence of exudate • Tooth mobility • Furcation involvement • Presence of calculus deposits on the teeth • Presence of dental plaque biofilm FGM slightly coronal to the CEJ - answer-normal positio
