Sweet Solutions: How Fruit Roll-Ups Can Improve Panoramic Radiography Quality

Fruit roll-ups aren’t just for kids’ lunches anymore! A new study shows that using these sweet treats can significantly reduce errors in panoramic radiography, ensuring clearer images and better dental diagnostics.

Panoramic radiography (PR) is a widely used diagnostic tool in dentistry, offering a fast and cost-effective method to examine dentofacial structures. However, various positioning errors can compromise image quality, potentially leading to misdiagnoses and the need for repeated radiographs, which increases radiation exposure for patients and technicians.

Patient positioning errors are the most frequent issues encountered during PR, occurring in nearly 95% of cases. These errors include improper head position, patient movement, and, most commonly, the failure to keep the tongue against the palate. This specific error creates a palatoglossal airspace (PGA) artifact, appearing as a dark band under the hard palate, which can obscure critical diagnostic regions.

Given the high incidence of PGA errors and the lack of practical solutions, a study, published in the Journal of Medical Radiation Sciences, evaluated the effectiveness of using celluloid matrix tapes and edible strips (fruit roll-ups) to ensure proper tongue positioning during PR, thus reducing the occurrence of PGA artifacts.


The study involved 270 patients divided into three groups: a control group receiving standard instructions to press their tongue against the palate, a celluloid strip group, and an edible strip group (using fruit roll-ups). The strips were placed on the tongue to help maintain contact with the palate during imaging. Radiographs were assessed blindly by an oral radiologist for the presence of PGA errors and categorized as excellent, diagnostically acceptable, or unacceptable.


The results showed significant differences among the groups:

  • Control Group: Highest frequency of unacceptable images.
  • Edible Strip Group (Fruit Roll-Ups): Highest frequency of excellent and diagnostically acceptable images, with the lowest occurrence of PGA errors.
  • Celluloid Strip Group: Effective but less so than the edible strip group.

Statistical analysis revealed no significant relationship between gender or age and the incidence of PGA errors. However, the type of strip material significantly influenced the quality of the radiographs, with fruit roll-ups proving most effective.

The study highlights the practical benefits of using fruit roll-ups to improve PR quality. The sourness of the fruit roll-ups helps stimulate salivation and muscle engagement, maintaining the tongue’s position against the palate more effectively than celluloid strips or standard instructions. Additionally, the opacity of the edible strips positively impacts image quality by minimizing the PGA artifact.


This study suggests that using fruit roll-ups during panoramic imaging can significantly reduce PGA errors, leading to clearer, more reliable radiographs. As an accessible and inexpensive solution, fruit roll-ups offer a practical alternative to traditional methods, enhancing diagnostic accuracy in dental practice.

Future research should explore similar innovative techniques to further minimize positional errors in dental radiography, potentially extending these findings to younger age groups under age 15. By improving patient cooperation and positioning accuracy, such methods can reduce the need for repeat radiographs and the associated radiation exposure, ultimately benefiting patient health and safety.
