There is abundant literature on electrosurgery dating back more than a century. During the past three decades, a substantial increase in minimally invasive surgery and microvascular surgery prompted greater use of electrosurgery. Although this surge in utilization has resulted in new applications, equipment features, problems and solutions, the use of electrosurgery in the field of restorative dentistry has remained relatively unchanged.

And even though both of these procedures are applied within several medical specialties, they are quite different in terms of both tools used and method of application. The electricity used is a form of alternating current similar to the that used to generate radio waves. This ensures that the current passes through the patients tissue as opposed to producing an electric shock effect.
The electrode selection depends upon and intended outcome.. These instruments can be used to cut, coagulate , or even to fuse tissue. It is not used to pass the current through tissue, but rather is applied directly onto the targeted area of treatment. Using this technique, heat is passed through a resistant metal wire which is used as an electrode. This use of electricity is typically applied in superficial situations encountered by dermatologists, ophthalmologists, plastic surgeons, urologists, and related specialties.
The bottom line here is that electrosurgery is not synonymous with electrocautery, despite their mutual use of electrical current to deliver their respective treatment goals. Download Our Free eBook: Understanding Electrosurgery Electrosurgery Applications Since the electrosurgery procedure is somewhat more complex than electrocautery, a bit of confusion over how it is used persists, even after the distinction between the two is understood.
There are two principle methods of employing electrosurgery: monopolar and bipolar procedures. In order to properly perform monopolar electrosurgery,.
The key difference between the two being that monopolar uses a grounding plate to direct the current, while bipolar employs opposing electrode points to accomplish the same thing.
Bovie Medical is proud to manufacture both electrosurgery and electrocautery products.

However, they are different from the standpoints of hemostasis, healing time, cost of instruments, width of the cut, anesthetic required and disagreeable characteristics, such as smoke production, odor of burning flesh and undesirable taste. Pre-operative picture shows fracture of teeth and gingival overgrowth. There is abundant literature on electrosurgery dating back more than a century. The waveform is chosen according to the desired periodonitcs of the tissue.

In human patients such stimulation may cause acute pain, muscle spasms, and even cardiac arrest. Sensitivity of the nerve and muscle cells to electric field is due to the voltage-gated ion channels present in their cell membranes. Stimulation threshold does not vary much at low frequencies so called rheobase -constant level. However, the threshold starts increasing with decreasing duration of a pulse or a cycle when it drops below a characteristic minimum so called chronaxie. Typically, chronaxie of neural cells is in the range of 0. Note that frequency of the alternating electric current is an inverse of the duration of a single cycle. Operation at higher frequencies also helps minimizing the amount of hydrogen and oxygen generated by electrolysis of water.
