Is acupuncturing effective in controlling the gag reflex during dental procedures? A review of literature.

Traditional acupuncture has been introduced more than 2500 years ago which provides an alternative and complementary option during clinical practices. Its main mechanism is based on stimulating the nerves by altering the processes and perception of pain transmitters. It facilitates releasing natural pain relievers such as endorphins and serotonin. Its success for various dental procedures has been proved earlier. However, its effects on controlling the gag reflex seem to be overlooked. The gag reflex is recognized as a protective reaction for stopping the entrance of any foreign bodies into the oropharynx. Pronounced gag reflexes can have negative impacts on the quality of dental procedures. Many techniques have been suggested for managing this reflex and acupuncturing is one of those which seems to be overlooked recently. The aim of this paper is reviewing the published high-quality researches about the efficacy of this technique for eliminating the gag reflex during dental procedures.
