During radiographic evaluation for periodontal disease, which projection provides the most accurate image for assessing interproximal bone levels?
Answer: Bitewing radiograph
Bitewing radiographs minimize distortion and provide the most accurate view of interproximal alveolar bone levels due to their standardized angulation.
Which finding during periodontal evaluation is most consistent with a diagnosis of necrotizing periodontitis?
Answer: Interproximal necrosis with cratering and fetid odor
Necrotizing periodontitis is characterized by interproximal necrosis, crater-like defects, spontaneous pain, and fetid odor caused by specific anaerobic pathogens.
In evaluating tooth prognosis, which factor carries the MOST negative weight according to the McGuire and Nunn prognosis system?
Answer: Furcation involvement Class II
Class II furcation involvement is one of the strongest negative prognostic factors because it significantly reduces long-term tooth survival, especially on maxillary molars.
A patient is evaluated 6 months after successful periodontal therapy. Full-mouth bleeding on probing is 8% and plaque score is 12%. How should this patient be classified for maintenance recall?
Answer: Low risk — every 12 months
BOP <10% and plaque score <20% combined with successful therapy indicate low periodontal risk, supporting an annual recall interval.
Which examination technique is used to evaluate the width of keratinized gingiva during a mucogingival assessment?
Answer: Measuring from the gingival margin to the MGJ
The width of keratinized gingiva is measured from the free gingival margin to the mucogingival junction, representing the total band of keratinized tissue.
During evaluation of gingival recession, the Cairo classification RT1 is defined by which characteristic?
Answer: Recession without loss of interproximal attachment
RT1 recession has no loss of interproximal clinical attachment or bone, offering the best prognosis for complete root coverage.
When evaluating the degree of tooth mobility, which classification system is most commonly used in periodontal practice?
Answer: Miller mobility index (I, II, III)
The Miller mobility index (Class I: 2 mm or vertical movement) is the most widely used classification in periodontics.
