Access and isolation problem solving in endodontics: anterior teeth.

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