Access and isolation problem solving in endodontics: posterior teeth

Through the pictorial presentation of case studies, this paper explores the versatility of alternative methods of retention as a means of improving overall access to the endodontically-involved tooth. Successful endodontics is the result of precise biomechanical instrumentation and involves procedural manipulations that depend on a complete and unobstructed approach to the working field. This paper is aimed principally at those practitioners who would ordinarily reject rubber dam isolation in cases where the clinical pretreatment conditions are anything but ideal.
