Periodontics questions for the ADC written exam.
Periodontics in the ADC written examination covers periodontal anatomy, aetiology and risk factors, diagnosis using the 2017 classification, non-surgical and surgical treatment, peri-implant disease and supportive care. Candidates should be able to assess risk, plan treatment and recognise when a patient should be referred to a specialist periodontist.

Key facts to remember.
High-yield periodontics points to revise before the exam.
- 1
Necrotising periodontal diseases present with painful, bleeding, necrotic interdental papillae and are associated with stress, smoking, poor nutrition and immunosuppression.
- 2
Furcation involvement is assessed by horizontal probing, for example with a Nabers probe, and worsens the prognosis of multirooted teeth.
- 3
Peri-implant mucositis is reversible soft-tissue inflammation without bone loss, whereas peri-implantitis also involves progressive loss of supporting bone.
- 4
Supportive periodontal therapy is usually provided at intervals of about 3 to 6 months, tailored to the patient's risk.
- 5
Periodontitis and diabetes have a two-way relationship, and periodontal treatment can produce a modest improvement in glycaemic control.

Questions, answered
Consider referral for advanced or rapidly progressing periodontitis, disease that has not responded to thorough non-surgical treatment, complex furcation or regenerative needs and patients with significant medical complications. Referral criteria vary between practices and guidelines, so focus on the clinical reasoning. In most cases, initial non-surgical therapy and reassessment come first unless the case is clearly complex.
Peri-implant mucositis is treated with improved plaque control and professional mechanical debridement and usually resolves. Peri-implantitis is managed with non-surgical debridement first and often surgical treatment, together with control of risk factors such as smoking, poor plaque control and a history of periodontitis. Regular maintenance with monitoring of probing depths and bone levels is essential for all implant patients.
