This study investigates the success rate of pulpotomy using electrosurgery operated on a primary molar in caries. The pulpotomy using electrosurgery was done on 253 primary molars of 111 young patients from 2 to 9 years old during the period of the first day of January 2011 to the last day of December 2015. After the amputation of pulp and hemostasis of primary molar were done using electrosurgery, MTA as pulp capping material was applied to the primary molar and the tooth was restored with the stainless steel crown. The follow up period after the treatment ranged from 4-46 months. The clinical and radiographic success rate ranged from 92.1 - 94.3%. Which is comparable to formocresol and ferric sulfate pulpotomy. Due to its non-pharmacological characteristic, electrosurgery can minimize harmful effect on the pulp tissue. Its fast bleeding control makes it easy and safe to use in pediatric and disabled patients in comparatively simple manner. Electrosurgery can be an alternative for pulp therapy considering the side effects of pharmacological ways.

Electrosurgery has been widely used in surgical procedures for many years. The surgical procedure using radiofrequency power generated occasionally sparks causing electrical stimulations. According to a paper of commercialized APC (Argon Plasma Coagulation) in the gastrointestinal endoscopy, Patients treated by APC had experienced pain and neuromuscular stimulation. This study aimed to investigate the electrosurgery sparks. In this experiment, current threshold of electrosurgery using rf was investigated. Sparks analogous to surgical situation was generated and measured the I-V figure. Asymmetric current, observed by other researchers, was also measured. This could be explained by difference between positive phase and negative phase. Furthermore, a method was developed to remove asymmetric current and to make safer device for surgical field.

Electrosurgical technique have been used in dentistry as an aid to soft tissue management for nearly 60 years. However, it was not until the late 1960s that the principles of electrosurgery were understood and improved equipment became available. Electrosurgery is a surgical procedure performed on soft tissue utilizing controlled high frequency electricaI(radio-frequency) currents in the range of 1,500,000 to 7,500,000 cyclesper second. The radio-frequency energy used in electrosurgery is able to cut and coagulate tissue because it focuses the energy at the small, active electrode. Advantages of electrosurgery for soft-tissue management during dental procedures include improved hemostasis, ease of tissue modification, improved visibility and so on, but adverse healing responses-including necrosis of soft tissue and sequestration of alveolar bone-have been reported. The present report provides examples of treatment of soft tissue and pulp tissue of primary teeth by electrosurgery. The results are as follows; 1. Electrosurgical techniques can be used for various procedures in pedodontics. 2. Electrosurgical procedures provide improved hemostasis and visibility in the operating field, which enable to remove, reshape, and contour soft tissues easily. 3. In pulpotomy technique, it was difficult to expect the variable pulpal response based on the degree of heat accumulation and the conditions of pulp tissues. Therefore, electrosurgical pulpotomy could not be considered as a method superior to formocresol pulpotomy. 4. A greater degree of dexterity and experiences in manipulation of the electrode is required compared with the conventional scalpel surgery.

Background: Selective health benefit was introduced for decreasing economic burden of patients. Medical devices with economic uncertainty have been covered as selective health benefit by National Health Insurance since December 2013. We aimed to analyze impact of selective health benefit to medical expenditure and provider behavior focused on electrosurgery (ultrasonic shears, electrothermal bipolar vessel sealers) for gastric cancer patients covered since December 2014. Methods: We used the National Health Insurance claims data of 2,698 patients underwent gastric cancer surgery between August 2014 and March 2015. Medical cost and patient sharing per inpatient day were analyzed to verify that covering electrosurgery increased medical expenditure and changed provider behavior from open surgery to endoscopic or laparoscopic surgery. Additionally, we analyzed the claim rate of medical device or goods relating gastric endoscopic and laparoscopic surgery. Results: Medical cost and patient sharing per inpatient day were increased after covering electosurgery as selective health benefit (39,724/1,421 won). However, there were no medical expenditure increases after adjusting claim of electosurgery and patient sharing was decreased 1,057 won especially. The coverage of selective health benefit did not increase the claim rate of medical device or goods related endoscopic or laparoscopic surgery, either. Conclusion: Covering electosurgery decreased patient economic burden and did not change of provider behavior. Expanding selective health benefit is needed to decrease economic burden of severe patients. Further study should evaluate the long term effect with accumulated data.
