Improving patient care: alternative rubber dam isolation methods

setembro 7, 2012

Adhesive techniques are more sensitive than conventional techniques and it is mandatory to isolate the operatory field. To accomplish this goal, rubber dam isolation is the gold standard procedure. In root canal treatment, use of a rubber dam is found to be the standard of care, however, it is usually abandoned by professionals as time progresses from graduation to professional life, since the prevalence of rubber dam use is found to be low in many studies. To increase the use of rubber dams, adaptations of traditional techniques have been suggested.  One possible way of reducing gingival trauma and pain promoted by isolation clamps during rubber dam usage would be the application of a thin layer of a soft material between the clamp and the tooth/gingival tissue. Objective: The purpose of the present work is to present alternative methods of rubber dam isolation, thus improving patient care. Description: Two methods are described: 1- Dam Coverage Method- Clamping the rubber dam over the tooth (putting the clamp over the dam and the teeth at the same time, without including the clamped tooth in the operatory field); 2- Silicone Coverage Method: Inter positioning of a heavy (high viscosity) silicone impression material between the tooth and the clamp. Conclusions: The current authors purposed two simple methods for absolute operatory field isolation using a rubber dam. These methods reduce sensitivity, provide little or no gingival trauma and better comfort to the patient during rubber dam isolation as well as in the postoperative period, thus improving patient care.
