Objective: Implantable cardiac pacemakers and cardiac defibrillators (ICDs) have been introduced in the care of patients with cardiac dysrhythmias. Most dental practitioners demonstrate extreme caution when treating patients with ICDs. This paper presents a review of the available literature on these devices and how they interact with dental electrosurgery and ultrasonic device use. Results: Based on the analysis of the literature, this view is not corroborated by the current clinical data, and appears to be misguided. While further in-vivo studies are needed to truly determine the true level of risk, the evidence suggests that there is no contraindication for electrosurgery or ultrasonics use in patients with ICDs. Conclusion: Using the precautions stated in this analysis, the risk of any deleterious effect on ICD function is minimal.
