A Comparative Study Between Manual vs. Electric Dental Anesthesia

Electric Dental Anesthesia (EDA) defined as a technique that achieving a local anesthesia by applying of “Transcutaneous Electrical Nerve Stimulation” (TENS). TENS first discovered in 1970s and introduced as “alleviate chronic pain” (intractable cancer pain, Phantom pain, back pain, …) and the acute pain in addition to find the utilities in areas of the sports medicine. The study aims to compare the effectiveness, onset time, and patient comfort levels between manual and electric dental anesthesia. It is hypothesized that electric anesthesia provides faster onset, lower pain perception, and higher patient satisfaction compared to manual methods. Despite the benefits, electronic anesthesia may have limitations including cost, equipment availability, and operator training requirements. However, its potential to improve patient experience and reduce failure-related complications justifies further investment and adoption in clinical practice.
