  1. Define a dental radiograph.
  2. Identify several types of radiographs commonly used in dentistry.
  3. Describe safety procedures used during radiographic procedures.
  4. Describe procedures for taking periapical radiographs, bitewing radiographs, and occlusal radiographs.
  5. Discuss how amalgam is mixed.
  6. Discuss the mixing of cements.
  7. Discuss how impression material is mixed.

  9. Identify several ways to foster long-term relationships with a dental laboratory.
  10. Identify some common pieces of laboratory equipment.


Radiographs, or x-rays, are an important diagnostic tool in dentistry. They can help the dentist detect dental problems that are not visible during a clinical exam. Several types of radiographs commonly used include bitewing, full-mouth series, panoramic, and periapical. Dental assistants must wear personal protective equipment during all radiographic procedures to ensure safety. This course describes several ways to minimize exposure during radiographic procedures. It also discusses the purpose of several intraoral procedures, including periapical, bitewing, and occlusal radiographs. This course describes radiograph surveys for: dentulous and edentulous adults, and children with primary and mixed dentition. Procedures are described for mixing amalgam, cements, and impression materials. It’s very important to work well with dental laboratories. Several guidelines are offered for fostering long-term relationships with dental laboratories. Common laboratory equipment is defined.
