Study Notes
Modified Dental Anxiety Scale (MDAS)
- Assesses anxiety levels about specific dental procedures
- Uses a 5-point Likert scale.
- Scores range from 1 (not anxious) to 5 (extremely anxious).
- Scores are interpreted based on sum score divided by 25.
- A score greater than 15 indicates dental anxiety, and greater than 19 indicates high dental anxiety.
- Any individual question with a score of 5 indicates anxiety.
Dental Fear and Avoidance Scale (DFAS)
- Assesses both fear and avoidance of dental treatment.
- Uses separate scales for both fear and avoidance.
- Scores range from 1 (no fear/avoidance) to 10 (extreme fear/avoidance).
- Scores are interpreted separately for fear and avoidance:
- 1-4: no/low fear/avoidance
- 5-7: moderate fear/avoidance
- 8-10: extreme fear/avoidance
Dental Belief Survey (DBS)
- Assesses patient beliefs and attitudes towards dental care and providers.
- Considers 3 dimensions: professionalism, communication, and lack of control.
- The number of questions varies between 14 to 28.
- Scores range from 1 (never) to 5 (nearly always).
- Sum scores are interpreted based on a range of 24 (highly positive) to 120 (highly negative) beliefs.
Index of Dental Fear and Anxiety (IDFA)
- Assesses anxiety associated with specific dental stimuli and situations.
- Measures anxiety about procedures, emotions, and provider behavior.
- Uses a 5-point Likert scale ranging from 1 (not at all) to 5 (very much).
- Higher scores indicate greater anxiety.
State-Trait Anxiety Inventory (STAI-State)
- Measures state anxiety as an emotional state.
- Assesses temporary feelings of tension, apprehension, and nervousness.
- Is used to assess the impact of situational factors on anxiety.
Attenuation
- Radiolucent areas appear darker on radiographic images as they are less dense and less mineralized.
- Radiopaque areas appear whiter on radiographic images because they are more dense and more mineralized.
Radiolucent Examples
- Air
- Depressions
- Foramina & canals
- Sutures
- Fossae
- Fissures
- Meati
Radiopaque Examples
- Spines
- Tubercles
- Tuberosities
- Prominences
- Septa
- Teeth
- Foreign body material
Intraoral Images
- Periapical Images capture a single tooth, showing the crown and root (anterior and posterior).
- Bitewing Images show the crowns of both upper and lower teeth, used to identify interproximal caries.
- Occlusal Images capture a full arch, showing the occlusal surfaces of the teeth (anterior and standard maxillary & mandibular occlusal).
Extraoral Images
- Panoramic images capture a wide view of both arches, showing the teeth, supporting structures, and surrounding anatomy.
- Focal trough is the curved area where the x-ray beam focuses, ensuring accurate image formation.
Teeth
- Crown is the visible part of the tooth above the gumline.
- Root is the portion of the tooth embedded in the bone.
- Enamel is the hard, outer layer of the crown, the most mineralized tissue in the body.
- Dentin is the layer beneath the enamel, a harder but less mineralized tissue.
- Pulp Chamber is the central part of the tooth containing the pulp, blood vessels, and nerves.
- Root Canal is the continuation of the pulp chamber in the root of the tooth.
Supporting Structures
- Trabecular/Cancellous bone is the spongy, porous bone found within the jawbone.
- Cortical bone is the dense, outer layer of bone surrounding the trabecular bone.
- Alveolar Crest is the highest point of the bone around the teeth, where the periodontal ligaments attach.
- Periodontal Ligament Space is the space between the tooth and the alveolar bone, containing the periodontal ligament fibers.
- Lamina Dura is the thin, dense layer of bone lining the tooth socket.
- Crestal Soft Tissues refer to the gingiva or gum tissue.
Trabecular Bone Variations
- Anterior Maxilla: Fine trabecular pattern with thin, numerous trabeculae and small, numerous marrow spaces.
- Posterior Maxilla: Fine trabecular pattern with thin, numerous trabeculae and numerous, larger marrow spaces compared to the anterior maxilla.
- Anterior Mandible: Coarser trabecular pattern with thicker, fewer, horizontal trabeculae than the maxilla and larger marrow spaces.
- Posterior Mandible: Horizontal trabeculae typically larger than in the anterior mandible, with larger marrow spaces, while fewer trabeculae are found inferior to the teeth.
Other Structures
- Restorative Materials include amalgam, composite, porcelain fused to metal, gutta-percha, and implants.
- Air appears radiolucent, allowing visualization of spaces and structures.
Attenuation Summary
- Most Radiopaque: Metal
- Radiopaque: Composite, Enamel, Bone
- Radiolucent: Soft tissues, Air
- Most Radiolucent: Air
