Positional Errors in Orthopantomograph – A Comparative Systematic Review with analysis of 1014 additional cases
European Journal of Molecular & Clinical Medicine,
2020, Volume 7, Issue 9, Pages 1711-1723
The purpose of our systematic review was to investigate the most common errors in the panoramic radiography and their impacts on the resultant radiographic film. The knowledge about the common positioning errors and the ways to rectify the errors, will benefit in producing high quality radiograph.
Material and methods
PubMed, ProQuest, Google scholar, Science direct and Scopus were screened for studies. Article selection and data extraction was done by one investigator and other investigator confirmed its accuracy.
Four hundred and seventy articles were initially identified from which eleven articles were full-text reviewed and included in the review. Additional 1014 radiographic cases were retrieved from the department of oral radiology and was assessed for various errors. Out of the eleven studies, the most common panoramic error encountered was, the tongue not placed on the palate and on the radiograph, it appeared as radiolucent band on the apex of the maxillary teeth.
To produce high quality radiograph, it is necessary for the operator to have a better communication with the patient and also to know about proper patient positioning.
