CNR and SNRs were also in favor of CBCT, though CBCT examinations exhibited significantly more beam hardening artifacts that diminished the advantages of the superior semi-objective image quality. These artifacts were believed to occur more often in children due to numerous bone-cartilage transitions in open growth plates and may have led to a better subjective diagnostic certainty rating (<jats:italic>p<\/jats:italic>\u00a0=\u20090.001). Motion artifacts were infrequently, but exclusively observed in CBCT.
