What are the 3 grades of radiographs?
What information is recorded in a radiographic report?
Grade 1 = excellent
Grade 2 = diagnostically acceptable
Grade 3 = unacceptable
Radiographic report; Type of radiograph and teeth shown Symmetry Margins Bone consistency
Dentition present; Heavily///minimally restored Restoration defects Caries Pathology

Summary
Treatment proposals
What information is recorded when observing peri-radicular changes?
Location
Size
Margins
What the changes signify
What is a radiolucency?
Loss of previously opaque material
Includes bone, teeth, caries and pathology
What is a radiopaque region on a radiograph?
Increased attenuation of material
Can be due to increased density, thickness
What is the radiological sieve for diagnosis?
Normal Developmental Traumatic Inflammatory Cystic Neoplastic Osteodystrophy Metabolic Idiopathic Iatrogenic Foreign body Artefact
Give examples of why a CBCT may be requested for a patient?
Implant planning Impacted teeth Pathology Orthognathic surgery Hypodontia Cleft palate Dental abnormalities Endodontic problems Autotransplantation
What is the general principle for selection criteria of radiographs?
A history and clinical examination are the only acceptable means for determining that the most appropriate and necessary radiographs views are requested
This ensures that all exposures will benefit the patient and will normally provide new information to aid the patient’s management or prognosis (justification)
What are the EADMFR basic principles on the use of a CBCT?
Use only when question cannot be answered adequately with a lower dose method
If evaluation of soft tissue is required
Use smallest volume compatible with clinical situation
Choose resolution compatible with area being examined
