Assigning a risk level

The diagram below shows a simplified illustration of the risk assessment process

Modifying Factors for Periodontal Diseases.

These modifying factors are associated with the development of periodontal diseases and should be considered when determining the risk-based frequency of recall for dental prophylaxis or supportive periodontal therapy.

• Bone loss observed on sequential radiographs
• BPE scores of 3, 4, or * in patients under 35 years of age
• Concurrent medical factor that is directly affecting the periodontal tissues (e.g. diabetes, stress, certain medications)
• Evidence of generalised chronic gingivitis
• Family history of chronic or aggressive (early onset/juvenile) periodontitis
• Family history of early tooth loss due to periodontal disease
• High percentage of sites which bleed on probing in relation to a low plaque index
• Poor level of oral hygiene
• Presence of plaque-retentive factors
• Previous history of treatment for periodontal disease
• Rapid periodontal breakdown >2 mm attachment loss per year
• Root morphology that affects prognosis
• Smoking 10+ cigarettes a day
