Association Between Dental Restorations and Artifacts on the Head MRI Images of Pediatric Patients
Objectives: Magnetic resonance imaging (MRI) has become an important diagnostic tool for pediatric patients since MR images are made with non-ionizing radiation. Limited information is available regarding the association of dental restorations and artifacts in MRI images. This study aimed to investigate the relationship between dental restorations and artifacts presented on the head MR images in children.
Methods: This retrospective study retrieved the clinical records of pediatric patients who underwent dental examinations and had a head MRI scan at Ramathibodi Hospital in Bangkok, Thailand. Information on the type of dental restorations was collected by a dentist. Two calibrated radiologists assessed the presence (yes/no) and location (oral cavity/maxillary sinus/brain) of the artifacts. Chi-square test was used to investigate the association between the artifacts and dental restorations.
Results: A total of 94 medical and dental records of pediatric patients aged 3-15 years old were reviewed. Approximately half (53%) of the children were male, and 90% of them were scanned with a 3 Tesla MRI machine. Among them, 26% and 47% had at least one stainless steel crown (SSC) and dental fillings, respectively. There was a statistically significant association between the presence of artifacts and the type of restorative materials (p<0.001). All children with SSC developed the artifacts located in the oral cavity (100%), in the maxillary sinus (92%), and in the cerebellum (4%). None of those with dental fillings had artifacts. The presence of artifacts was not associated with the child’s gender and type of MRI machine.
Conclusions: Artifacts are significantly associated with the type of dental restorations in children. The presence of SSC is highly related to the development of artifacts in the oral cavity and maxillary sinus.
