Acupuncture, Anesthetic Spray, or Masking Tape for Gagging
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests three methods to reduce the gag reflex: acupuncture, anesthetic spray (a numbing agent), and masking tape. The goal is to assess how each method affects the gag response when triggered. It is ideal for individuals who frequently experience gagging, particularly during dental visits, and have a strong gag reflex when a swab touches the back of the mouth. Participants should belong to the Tufts dental community and have a noticeable gag reflex. As an Early Phase 1 trial, this research aims to understand how these methods work in people, offering participants a chance to contribute to pioneering solutions for managing gag reflexes.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but if you are using anticoagulants (blood thinners), you cannot participate.
What prior data suggests that these techniques are safe for reducing gag reflex?
Research has shown that acupuncture, particularly at a point called CV-24, can safely and effectively manage the gag reflex. This quick and non-invasive method takes just a few minutes, and studies indicate that most people tolerate it well.
In contrast, anesthetic sprays, often containing benzocaine, present some safety concerns. Benzocaine can rarely cause methemoglobinemia, a serious condition affecting how blood carries oxygen. Ensuring no allergy to benzocaine or similar substances is crucial.
Using masking tape is a simple and non-invasive method to help manage the gag reflex by acting as a physical barrier, and no significant safety issues have been reported with its use.
Each treatment has its own safety considerations, so weighing options or consulting a healthcare provider is important.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for gag reflex management because they offer non-traditional, innovative approaches that could provide new options for patients. Unlike standard methods like desensitizing agents or behavioral techniques, acupuncture at the mentolabial fold (CV-24) uses a novel application technique with an endodontic file, which may offer a unique reflex modulation. The anesthetic spray provides a quick, direct application to the throat, potentially offering fast-acting relief. Meanwhile, applying masking tape to the mentolabial fold is an unexplored method that might offer a simple mechanical solution to reducing gag reflex. These diverse strategies could revolutionize gag management by offering alternatives that are potentially quicker or more accessible than current treatments.
What evidence suggests that this trial's treatments could be effective for reducing gag reflex?
This trial will compare the effectiveness of acupuncture, anesthetic spray, and masking tape in reducing the gag reflex. Research has shown that acupuncture at a specific point, called CV-24, can quickly reduce the gag reflex during medical procedures. Participants in this trial may receive acupuncture as one of the treatment options. Anesthetic sprays, another treatment option, have proven effective, as evidence indicates they greatly reduce gagging compared to not using them. Specifically, one study found that people who used an anesthetic spray had a much lower gag reflex than those who did not. As for masking tape, the third treatment option, specific data on its effectiveness in reducing the gag reflex is limited, but it is being explored as a possible method.12678

Are You a Good Fit for This Trial?
This trial is for individuals aged 18 or older who are part of Tufts SDM and have a strong gag reflex, scoring at least a 2 on the Gagging Severity Index. Participants must react to cotton swab stimulation in their mouth. Pregnant women, those allergic to xylocaine, using anticoagulants, with bleeding disorders, or unable to consent due to cognitive impairment cannot join.Inclusion Criteria
