Final answer:
The incorrect statement regarding the cut ligature pigtail is B. Tuck toward the occlusal, as the correct method is to tuck the pigtail toward the gingiva to prevent patient discomfort.
Step-by-step explanation:
The statement that is incorrect regarding the cut ligature pigtail is B. Tuck toward the occlusal. In orthodontic treatments, after tying the archwire to the bracket using a ligature, the excess wire (the pigtail) is typically trimmed and then tucked in to prevent irritation to the patient's mouth. The correct procedure is to tuck the pigtail toward the gingival (gum) and make sure it's placed in the interproximal space, which is between two teeth. After tucking the pigtail, it's recommended to run a finger over them to check for comfort to ensure that it does not cause discomfort or injury to the patient's cheeks, lips.
