Abstract

Introduction: Metal artefact is the most common type of artefact in computer tomography (CT) imaging which can affect the diagnostic image quality. Objective: To evaluate the artefact intensity from different types of orthodontic brackets (stainless steel, titanium, monocrystalline, ceramic) in craniofacial CT scan. Methodology: This is a prospective in-vitro cross-sectional study. Four types of orthodontic brackets were bonded to the tooth surfaces (from right second premolar to right central incisor for both arches) on a human cadaveric skull consecutively. All scans were done by a single operator using same CT machine (TOSHIBA CGGT-032A) following a standard scanning protocol (kvp-120, exposure time-500, x-ray tube-200, slice thickness 1mm). Artefact intensity for images were measured by calculating their maximum, minimum & mean grey values by using ImageJ software (ImageJ version 1.50i). One-way ANOVA post hoc analysis was used for the data analysis. Result: From this study, the artefact intensity for stainless steel bracket revealed a higher mean value compared to the other three types of the brackets. The mean values of the artefact intensities are: stainless steel bracket (1.64), titanium (1.56), monocrystalline (1.49) and ceramic (1.47). A significant difference (p=0.007) of artefact intensity between stainless-steel and ceramic bracket was observed. Conclusion: A difference in artefact intensities were observed depending on the types of the brackets. Stainless steel bracket showed more artefact compared to other type of brackets.
