ChemoRT With and Without Dental Stent for Taste Protection in NPC Patients

Dental stent is personalised device for tongue depressing and immobilisation during RT. The aims are to reduce unnecessary RT doses to adjacent non-target healthy tissue, including the tongue, adjacent oral mucosa, parotid glands/ submandibular glands, and temporomandibular joints. Dentists will take impression of the teeth on moulds, and measure the height to raise the bite, the stent is then fabricated as methyl methacrylate resin in the dental laboratory. The resin base extends to the tongue and a flat plate depresses the tongue. This device will be placed before each RT fraction.

No dental stent used during chemoradiation treatment
