INSTRUMENTS FOR PROVIDING SUCTION
To provide adequate visualization, blood, saliva, and. irrigating.solutions must be suctioned from the operative site. The surgical suction is one that has a smaller orifice then the type used in general dentistry so that the tooth sockets can be suctioned in case a root tip is fractured and adequate visualization is necessary. Many of these suctions are designed with several orifices so that the soft tissue will not become aspirated into the suction hole and cause tissue injury (Fig. 6-31, A).
The Fraser suction has a hole in the handle portion that can be covered as the requirement dictates. When hard tissue is being cut under copious irrigation, the hole is covered so that the solution is removed rapidly. When soft tissue is being suctioned, the hole is uncovered to prevent tissue injury (Fig. 6-31, B).
