Certain dental procedures require patients to be without their removable partial dentures. This can be a great inconvenience and psychologically difficult for some patients. This procedure permits duplicating existing removable partial dentures so that patients will not have to be without prostheses.
Parallax error is found to be another pitfall in pinhole thyroid scintigraphy, i.e., a substernal goiter may appear between the thyroid cartilage marker and the suprasternal notch marker. Unless one is aware of this pitfall, a substernal extension of the thyroid may not be realized or be seriously underestimated in its size and extent. We illustrated the parallax error using a thyroid phantom. An illustrative case is shown.
