Artifacts Of MRI In Oromaxillofacial Region-Systematic Review And Meta Analysis

Abstract

Introduction: In order to determine whether the artifacts interfere with accurate diagnosis in the head and neck region, current systematic review searched the literature for severe unintended consequences of dental materials in magnetic resonance imaging (MRI).

Methodology: This study covered clinical papers demonstrating the severity of artifacts dental materials can produce in head and neck MRIs, including their impact on diagnostic precision. The searches were done manually in the reference lists of papers that passed the full-text reading screening and in four electronic databases. The " Robvis (visualization tool for risk of bias assessments in a systematic review)" was used to evaluate bias risk. The GRADE system was used to grade the strength of the evidence.

Results: 19 studies, were chosen for full reading, were deemed appropriate for this review. It is generally known that orthodontic appliances can produce artifacts, and in MR imaging of the head and neck, stainless steel brackets are the materials most prone to do so. There was a dearth of literature on dental implants and restorations. Affected diagnoses included those of the mouth, the brain, and the craniofacial tissues.

Conclusion: Orthodontic artifacts may interfere with the diagnosis of craniofacial and oral structures. Data on prosthodontic restorations and dental implants were inconclusive. Dental material characteristics, position in the oral cavity, and magnetic resonance parameters all affect how severe MRI artifacts are and how they affect diagnosis.
