Study Notes
Diagnostic Records in Orthodontics
- Diagnosis is defined as identifying the nature and cause of a disease/injury, as well as the opinion derived from that evaluation.
- Orthodontic diagnosis requires a comprehensive database of patient information, considering both patient perceptions and doctor observations.
- A problem-oriented approach, crucial in medicine and dentistry, ensures thorough consideration of all aspects of the patient's condition.
- Orthodontic diagnostic records originate from interviews, clinical examinations, and evaluation of records.
- Diagnostic records are used for diagnosis and treatment planning, monitoring growth and treatment, medico-legal records, patient communication, and audit/research.
- Orthodontic diagnostic records include radiographs, photographs, and study models.
Radiographs
- Radiographs carry a low risk; clinical justification is crucial before prescribing.
- Radiographs can provide information on the presence/absence of teeth, stage of permanent dentition development, root morphology, and presence of ectopic/supernumerary teeth.
- Radiographs commonly used in orthodontic assessment include: dental panoramic tomography (DPT/OPG), cephalometric lateral skull radiographs, upper standard occlusal radiographs, periapical radiographs, and bitewing radiographs.
- Orthopantomographs (OPG) are crucial for detecting pathologies in general, determining tooth number/size/shape, eruption status of succedaneous teeth, tooth material dimensions, and medicolegal purposes.
- Advantages of OPG include large anatomical area visualization, low radiation, and minimal interoperator variation.
- Disadvantages include specialized equipment requirements and potential distortions/magnifications of structures.
- Intraoral periapical radiographs (IOPA) are still used.
- Bitewing radiographs are ideal for detecting proximal caries and interdental bone.
- Occlusal radiographs view incisor region, assessing root form, and detecting ectopic canines.
Computed Tomography (CT)
- Cone-beam computed tomography (CBCT) is a faster, more compact version of traditional CT with a lower radiation dose, producing 3-D views.
- CBCT is useful for accurate location of impacted teeth, assessing alveolar bone coverage/height/volume, and TMJ/airway analysis.
- CBCT is used in complex orthodontic cases and when conventional radiography isn't sufficient.
Photographs
- Extraoral photographs are essential for before and after treatment, and assessing craniofacial relationships/proportions.
- Extraoral photos include frontal facial (relaxed/smiling), facial profile (relaxed), and three-quarter views.
- Intraoral photographs document teeth and soft tissue health. They include a frontal view with teeth in maximum intercuspation, two lateral (right/left) views, and two occlusal views (maxillary/mandibular with retracted tongue).
Study Models
- Study models are accurate plaster reproductions of teeth and supporting tissues, crucial for comprehensive occlusal and dentition analysis.
- Ideal study models are symmetrical, accurate, and have smooth, bubble-free surfaces.
- Study models are essential for treatment planning, identifying discrepancies, understanding changes during treatment, and medicolegal purposes.
