Study Notes
Justification of Radiographs
- It is essential the benefits of taking radiographs to outweigh the harm caused to the patient.
- This ensures patient safety while allowing for diagnoses and appropriate treatment.
Learning Outcomes
- Students can explain the principles of interpreting dental radiographs.
- Students can differentiate between various types of dental radiographs.
- Students can identify radiographic anatomy and assess changes in common diseases.
GDC Learning Outcomes
- 1.1.2; 1.2.5; 1.2.7; C1.15, C1.17, C2.1.4, C2.1.8, C2.3.1
Important Considerations
- This lecture focuses on interpreting dental radiographs and does not cover other aspects relevant to dental radiology.
Radiographic Film Types
- Analog or chemical processed films.
- Photostimulable phosphor plates.
- Solid state detectors.
Diagnosis
- Clinical Exam: It is important to assess a patient’s history and determine what can be observed clinically.
- Medical History: This information regarding a patient’s past health can influence the justification for taking a radiograph.
- Dental History: Previous dental treatments or problems should be considered.
- Social History: Lifestyle habits such as smoking or alcohol consumption can affect dental health.
- Special Tests: Tests such as a cold test can help assess pulp vitality.
- Severity: Determining the level of the problem.
- Radiological Examination: Analyzing the radiographic images.
Principles of Interpreting Dental Radiographs
- Recognizing types of radiographs and their anatomy: This includes recognizing variations and anomalies in anatomy.
- Assessing lesions: This entails considering:
- Location
- Description
- Shape
- Size
- Symmetry
- Borders
- Relationship to other structures
- Linking interpretation to clinical evaluation: This includes recording findings and using these findings as visual aids during treatment.
Types of Radiographic Views
Bitewing (BW)
- Horizontal Bitewing:
- Horizontal view of upper and lower posterior teeth.
- Covers the posterior of the canine to the first molar.
- Used to assess:
- Proximal carious lesions.
- Depth of carious lesions.
- Pulp horn and chamber.
- Alveolar bone crest.
- Vertical Bitewing:
- Vertical view of upper and lower posterior teeth.
- Covers the posterior of the canine to the first molar.
- Provides a specific view of a particular area.
- Used to assess:
- The same reasons as horizontal BW.
- Root morphology.
- Furcation regions.
- Unerupted permanent successors.
Periapical (PA)
- Provides a view of the whole tooth, including the root and underlying supporting alveolar bone structure.
- Used to assess:
- Root morphology.
- Apical pathology.
- Position of underlying structures.
- SLOB rule (Same Lingual Opposite Buccal).
DentoPanTomograph (DPT) or OrthoPantomoGraph (OPG)
- Provides an overview of the lower half of the skull, including the maxilla and mandible.
- Used to assess:
- Position of objects in relation to other structures.
- Broad overview of the maxilla and mandible.
- View of the condyles.
Occlusal
- View of anterior teeth, including root morphology and apex, usually used for uncooperative children and trauma cases.
- Used to assess:
- Underlying developing permanent successors in pediatric cases.
- Can be an alternative to multiple PA views.
Cephalometric
- Lateral view of the skull.
- Used to assess the position of teeth in relation to the jaw and other fixed landmarks of the skull.
Lateral Oblique (Bimolars)
- Provides a view of posterior teeth.
- Used when patients cannot cooperate for BW or DPT.
Other Radiographic Views
- Specialised radiographs for implant placement and endodontic treatment.
- High Radiation levels require these procedures to be conducted with caution.
Key Terms
- Radiolucency: A dark area on the radiograph that indicates a less dense tissue.
- Radiopaque: A white area on the radiograph that indicates a dense tissue.
Important Considerations Regarding Radiographic Interpretation:
- Image quality should be diagnostically acceptable.
- Establishing a viewing routine ensures consistency and helps avoid missing details.
- It's vital to understand "normal" anatomy, variations of "normal" anatomy, anomalies, lesions, and artifacts.
- A systematic approach to radiographic interpretation is essential.
- It's crucial to consider clinical information alongside radiographic findings for accurate interpretation.
