      The purpose of this investigation was to investigate intraoral radiography in regards to the frequency of errors, the types of error necessitating retakes, and the relationship of error frequency to the teeth area examined and type of x-ray cone used. The present study used 283 complete mouth radiographic surveys made by junior dental students. A total of 6,763 exposures were made, and 890 radiographs were found to be clinically unacceptable for one or more errors in technique. Thirteen and one-tenth errors per one hundred radiographs were found in this study. The three major radiographic errors occurring in this study were incorrect film placement (49.9 percent), cone-cutting (20.8 percent), and incorrect vertical angulation (12.5 percent).
