The purpose of this study was to contrast histologically the pulp response to formocresol with the response to electrosurgical pulpotomy in a primate model. Both the primary and permanent incisors and molars were treated. Coronal pulp amputation was accomplished mechanically. The remaining pulp stumps were treated by either formocresol or momentary electrosurgery exposure. Results were evaluate...

INTRODUCTION: Ultrasonic energy surgical cutting devices are used to simultaneously cut and coagulate soft tissue and vessels. However, the extent of nerve damage that may result from their application in close proximity to a nerve is not clear. Hence, the purposes of this study were to determine the effects of ultrasonic (US) energy surgical cutting devices on sciatic nerve function when appli...

Introduction Soft tissue surgical lasers have many advantages over traditional scalpel surgery, cryosurgery, and electrosurgery. However, not all lasers are equally efficient at both cutting the soft tissue, coagulating, and hemostasis because light absorption in the soft tissue varies with wavelength.1-3 As illustrated in Figure 1, some dental laser wavelengths (around 1,000 nm, such as diodes...

A 32-year-old female American flamingo (Phoenicopterus ruber) was presented with a squamous cell carcinoma of the middle digit of the right foot. No clinical, hematologic, or radiologic evidence of metastasis was present. Salvage amputation of the digit resulted in complete cure, whereas previous electrosurgery and radiation therapy were unsuccessful. Three years later, another squamous cell ca...

Historically, oral soft tissue surgery on infants and young children was completed in the operating room under a general anesthetic agent. Many children were referred to an oral surgeon and required a physician's physical examination and medical clearance for a hospital admission. potentially placed a child at risk during the use of a general anesthetic for an elective procedure, which may not ...

Colorectal polypectomy is an effective method for prevention of colorectal cancer. Many endoscopic instruments have been used for colorectal polypectomy, such as snares, forceps, endoscopic clips, a Coagrasper, retrieval net, injector, and electrosurgery generator unit (ESU). Understanding the characteristics of endoscopic instruments and their proper use according to morphology and size of the...

Electrosurgery, laser ablation, and ultrasonic scalpel dissection create a gaseous by-product commonly referred to as surgical smoke or plume. Smoke evacuation devices have been shown to be effective in limiting exposure to the noxious odor and potential health hazards of smoke and plume; however, these devices have not been used routinely and consistently in many ORs. This article reviews five...
