Study Notes
Dental Film X-ray
- Functions as an image receptor for recording dental X-rays by exposing film to x-radiation or light.
- Four basic components of dental film include:
- Film Emulsion: Increases film sensitivity to radiation.
- Film Base: Made of flexible polyester plastic, resistant to heat, moisture, and chemicals.
- Adhesive Layer: Bonds the emulsion to the film base.
- Protective Layer: Thin transparent coating that safeguards the emulsion from damage.
Types of Dental X-ray Film
- Extraoral Films:
- Positioned outside the mouth during exposure to examine wider areas like the skull and jaws.
- Examples include:
- Panoramic Films: Capture full panoramic view of teeth and jaw.
- Cephalometric Films: Analyze dental structures in relation to the head.
- Intraoral Films:
- Positioned inside the mouth for more localized imaging.
- Types include:
- Periapical Film: Focuses on entire tooth structure including roots.
- Bitewing Film: Captures the crowns of upper and lower teeth.
- Occlusal Film: Large film for examining extensive areas of maxilla or mandible.
Parts of Dental X-ray Film
- Outer Package Wrapping: Soft vinyl or paper that protects against light and saliva exposure.
- Paper Film Wrapper: Black protective sheet that shields the film from light leaks.
- Lead Foil Sheet: Positioned behind the film, it prevents back scattered radiation that can cause film fog.
X-ray Film Processing
- Involves two main solutions:
- Developer: Initiates the development of the image.
- Fixer: Stabilizes the developed image to prevent further exposure.
History of Dental X-rays
- Key figures in dental radiography:
- Wilhelm Conrad Roentgen: Discovered X-rays in 1895.
- Dr. Otto Walkhoff: First dental X-ray exposure of a living patient (1896).
- Dr. Edmund Kells: Achieved the first intraoral X-ray of a patient.
- William Rollins: Developed the first dental X-ray unit.
- William D. Coolidge: Invented the "hot cathode" X-ray tube.
Uses of Dental Radiographs
- Detects lesions, diseases, and conditions not visible clinically.
- Confirms or classifies suspected diseases.
- Localizes lesions or foreign objects.
- Provides crucial information for dental procedures like root canal therapy.
- Evaluates growth and development.
- Illustrates changes over time in dental structures.
