简要总结
The purpose of this study is to test photobiomodulation (PBM) with a non-invasive light device for reducing discomfort during dental treatments in children. We plan to conduct a series of three clinical studies in 200 school-aged children requiring routine dental treatment. The first study aims to test if PBM works for tooth and soft tissue by assessing response to cold testing and probing of gums. The second study aims to test if use of PBM on soft tissues before injection reduces discomfort. The third study aims to test if PBM can be used to do simple dental fillings in baby teeth without numbing injection.
详细描述
Dental anxiety and fear of pain during procedures are major barriers to oral health care, especially among children. Traditional local anesthesia injections can be distressing for pediatric patients. The fear of needle and dental pain are perhaps among the top reasons for avoidance of dental care. Photomodulation (PBM) is a promising non-tissue penetrating (i.e. minimally invasive) approach for achieving tooth and soft tissue anesthesia/analgesia in dental patients.Investigators plan to use an intra-oral PBM device with a tip comprising of a series of photonic emitters with specific wavelengths that can go through the tooth structure and bone, blocking the nerve conduction like local anesthetics. Research has shown that one burst of light application (for about 20 second) can provide up to 15-20 minutes of pain relief. This could significantly reduce dental anxiety and facilitate access to care and the implications of such an alternative to needles will be a gamechanger especially in pediatric dentistry. The proposed randomzied clinical trials will evaluate if photobiomodulation (PBM) with the near-infrared device produces dental analgesia comparable to local anesthetic injection in pediatric patients. This will be a series of three prospective, clinical studies in 200 school-aged children aged 6-12 years requiring routine dental procedures. The first trial will test the effectiveness of PBM in tooth and soft tissue analgesia by assessing response to diagnostic approaches such as cold pulp testing and gingival probing. The second trial will assess the pre-emptive analgesic effect of PBM on soft tissues at the site of injection prior to local anesthesia infiltration to reduce the discomfort of injection, and the third trial will assess effectiveness of PBM in providing tooth analgesia (compared to routinely used topical anesthesia/local infiltration) for simple restorative procedures in primary teeth.

结局指标
主要结局
Study 1- Response to Cold Pulp (Pulp sensibility) testing
时间窗: during the intervention (application of cold stimuli)
Name of measurement: Response to cold pulp testing. Measurement tool: Child's acknowledgement of cold sensation. A small amount of cold spray (Endo Ice/Ethyl Chloride) will be sprayed onto a cotton pellet, and gently place the cotton pellet on the middle third of the buccal surface of the tooth for a few seconds or until the child indicates a sensation. Child will be asked to raise their hand when they feel a cold sensation. Unit of measurement: Response will be noted (Yes/No), if the cold sensation is felt by the child on application of cold stimulus. Difference in cold pulp testing between PBM and no PBM group.
