[TENS as an alternative analgesic treatment in dental settings]

The use of electrostimulation using low-intensity and very high frequency current, as an Electronic Analgesic (EDA) has aroused enormous interest during the last few years in Dentistry. Thanks to its use, good results have been obtained especially in the treatment of caries. This technique is suitable for several types of patients as those who have previously shown anaphylactic-anaphylactoid reactions to local anaesthetics, those who are afraid of needle, those who underwent to coronaric by-pass or have had myocardial infarction, those who employ omeophatic therapy and refuse traditional drugs and those who are in anticoagulant therapy, where it is preferable to avoid injection trauma. This technique offers a rapid disappearance of the effects and makes it possible to work in the same sitting on more than one quadrant of the mouth. The application of the technique instead shows relative or absolute contraindications in patients with pace-maker or with an history of alteration of rhythm, cerebral ictus or TIA.
