viewed through ceiling lights.
7) The dental radiographer should always mount films _____ after processing.

• Divide the class into 5 groups, and assign each group one of the 5 reasons why a film mount is
used in dental radiography. Have each group summarize and provide detailed examples of
their reason. Have the students present their findings to the class.

necessary information on the film mount. Check the students’ work for accuracy.
• Appropriate Settings: Traditional classroom, flipped classroom
• Utilize the mounted films from the previous exercise; remove the films from the mount. Divide
the class into small groups, and have each group remount the films using the identification dot
to orient the films into the mount. Provide feedback as necessary.
