What equipment is commonly used for suctioning during surgical procedures?

The use of a saliva ejector or suction tip is essential during surgical procedures for a few key reasons. These devices help maintain a clear and dry surgical field by removing saliva, blood, and other fluids that can obstruct visibility and hinder the surgeon's ability to operate effectively. The suction tip can efficiently remove larger volumes of fluid, making it especially useful in surgical contexts where precision is critical.

In contrast, other equipment mentioned does not serve this purpose. A low-speed handpiece is typically used for removing decay or polishing teeth rather than suctioning fluids. An infrared camera might be employed for diagnostic or imaging purposes but is not relevant to the immediate needs of suctioning during surgery. Lastly, an orthodontic scaler is specialized for removing calculus and debris from teeth, not for suctioning fluids during procedures. Therefore, the saliva ejector or suction tip is the most suitable choice for maintaining the surgical environment.
