As the literature review will establish, it is regarded by most investigators as bacterial in origin, but with many other local and possible systemic conditions altering the progress of the disease. The study of pulpal form and anatomy has been of interest to the dental profession since the beginning of modern dentistry. The possible sequela and relationship to periodontal and pulpal interaction is not new to the literature, although there has been a revitalized interest in this area within the last decade. The presence, incidence and location of accessory pulpal canals have been studied by various techniques with varying results.
