Quality assurance of indirect restorations should be performed by the dental laboratory before delivering the prosthetic parts to the clinician. Ultimately, it is the clinician’s responsibility to inspect and ensure, within the limits of clinically available technical and technological means, the quality of the prosthesis prior to insertion. Transillumination techniques in dentistry have been described as an aid in diagnosis as well as during the execution of various clinical procedures, including those for interproximal caries detection,1 endodontic visualization of dentinal defects,2 surgical localization of retained roots,3 location of the maxillary sinus floor and septa during sinus augmentation procedures,4 diagnosis of occult submucous cleft palate,5 and as a facilitator during arthroscopic puncture.
