OBJECTIVE: This study evaluates artifacts generated by orthodontic brackets in CBCT images. METHODS: Cadaver heads with restoration free dentitions were prepared. CBCT scans with four orthodontic bracket materials utilizing thermoplastic carriers and a control were compared in three phases. RESULTS: Stainless steel brackets caused statistically significant (P<0.0001) differences from the control in the three phases. CONCLUSION: These observations support the hypothesis that metallic and nonmetallic orthodontic brackets interfere with the diagnostic quality of CBCT images.
