Questions and Answers

Which of the following best describes horizontal bone loss?

2024 BOH1: Radiology and Periodontal Patterns of Bone Loss

  • Presentation by Eduardo Delamare BDS, MSc (DMFR)
  • Email: [email protected]
  • Contributors: Dr Antonia Scott and Dr Malcolm I Coombs

Adult Patient: History and Examination

  • Complete a thorough history and clinical examination of the tooth-bearing areas before taking any radiographs
  • Seek originals or copies of radiographs taken elsewhere, if relevant
  • Do not perform screening or routine radiographs.
  • Avoid taking new radiographs without examining existing ones.
  • Avoid panoramic radiographs for all patients
  • Do not use a single protocol for all patients

Reading Radiographic Images

  • Angulation (horizontal, vertical)
  • Orientation
  • Soft tissue shadows
  • Magnification

Periodontal Conditions

  • Indications for intraoral radiographs:
    • Bone level assessment
    • Alveolar crest condition
    • Furcation area bone loss
    • Periodontal ligament width
    • Local irritating factors increasing periodontal disease risk (e.g., calculus)
    • Poorly contoured or overextended restorations
    • Analysis of root length and morphology/crown-to-root analysis
    • Open interproximal contacts (potential food impaction)
    • Maxillary sinus position relative to periodontal deformity
  • Prescription of radiographs: Bisecting vs Paralleling in Periodontics
  • Periodontal Patterns of Bone Loss

Periodontal Classification (Table 20.1)

  • Categorizes periodontitis based on several criteria (stage, severity, complexity)
  • Includes I, II, III, and IV stages, considering radiographic bone loss, probing depths and complexities of different types of bone loss (e.g., Maximum probing depth, horizontal bone loss)

Periodontal Conditions: Recommendations

  • Generalized pocketing (up to 4-5mm or greater than 6mm)
  • Horizontal bitewings
  • Periapicals with paralleling technique (or vertical bitewings)
  • Health vs Affected X-rays (identification of affected vs healthy teeth)
  • Localized vs Generalized Patterns
  • Types of bone loss (horizontal, vertical, furcation involvement)

Periodontal Patterns of Bone Loss: Horizontal Bone Loss

  • Extension: coronal 1/3, mid 1/3, apical 1/3
  • Health vs. Coronal 1/3 (identification of bone loss in coronal 1/3 of the tooth)

Periodontal Patterns of Bone Loss: Vertical Bone Defects

  • Types: three-walled, two-walled (craters)*

Periodontal Patterns of Bone Loss: Vertical Bone Loss

  • One-walled (description)

Periodontal Patterns of Bone Loss: Furcation Involvement

  • Early vs Moderate/Severe

Periodontal Patterns of Bone Loss: Local Irritating Factors

  • Calculus
  • Defective restorations

Prescription of Diagnostic Imaging

  • Bitewings
  • Vertical bitewings
  • Periapical radiographs (paralleling)
  • OPG (overview of teeth)
  • CBCT (Cone Beam CT) scanning

Periodontal Conditions: Recommendations

  • CBCT not routinely used for periodontal bone support
  • Periapical with Paralleling for indicated lesions
  • Panoramic, supplementary periapicals, or complete series of periapicals for comprehensive assessments
