TENS, or Transcutaneous Electrical Nerve Stimulation, is a technique that is used to manage pain. It is generally safe when used correctly, but it is not suitable for everyone. If you are considering using TENS for back pain, it is important to speak to your doctor first. Your doctor may advise against using TENS if you have a pacemaker or if you are in the first few weeks of pregnancy. Local anesthesia is an important part of pain management in dentistry, especially when it comes to children's dentistry.
A review of four studies that compared TENS with placebo showed conflicting evidence, making it difficult to determine if TENS is effective in reducing back pain. During a TENS treatment, electrodes are placed on the skin over the affected area on the back. A conventional TENS device typically produces low intensity pulsed currents with a high frequency. When it comes to children's dentistry, the solution is deposited supraperiosteally and infiltrates through the alveolar bone until it reaches the apex of the root. This is because the alveolar bone in children is more permeable than in adults.
