Researchers looked at data from 1,519 patients undergoing dental and facial procedures. They compared a light therapy called photobiomodulation to other methods, such as no treatment or a placebo, to see if it helped reduce pain when a needle is used to deliver local anesthesia.
The analysis found that patients who received the light therapy reported lower pain scores across several different measurement scales. However, the researchers noted that the evidence is not very strong. There was a lot of variation in how the studies were conducted, and the quality of the data was rated as very low by the experts.
Because the evidence is limited, it is not yet clear how much this treatment will help in a typical dental office. It may be a helpful extra step for patients who are anxious or for children, but more high-quality research is needed. You should talk to your dentist about whether this option is right for your specific needs.
Common questions
Can light therapy help with dental needle pain?
The study suggests that preemptive photobiomodulation therapy may reduce pain scores during needle punctures. While the results show a reduction in several pain scales, the evidence is currently rated as very low certainty. This means while it shows promise, more research is needed to confirm its effectiveness.
Who is this treatment most helpful for?
This noninvasive light therapy may be particularly helpful for patients who are anxious or for children. It could improve comfort and cooperation during dental and craniomaxillofacial procedures. You should discuss your concerns about needle pain with your dental provider.
Is this treatment safe for dental patients?
The study did not report any specific adverse events or safety concerns regarding the light therapy. However, because the evidence is limited and the study quality was low, you should consult your healthcare provider to discuss the best way to manage your comfort during procedures.
