Polyethylene tubes, closed at both ends with casting wax and with four perforations in the middle, were implanted subcutaneously in rats and evaluated as a research model simulating the root canal. As controls, wax bars and unperforated tubes were im

Summary. The root canals of 97 extracted, single-rooted teeth were prepared and filled by thermomechanical compaction of gutta-percha and an additional 17 teeth were used unfilled as controls to observe dye penetration. By varying the size of the mas

Two series of experiments were conducted on the reactions of the living organism when in contact with dead and fixed dead tissue. The inflammatory reaction to necrotic tissue was less severe than the reaction to fixed necrotic tissue. The results led

Searching for an experimental model simulating the root canal, a two-stage procedure was evolved using polyethylene tubes implanted subcutaneously in rabbits. The reaction to the model was histologically evaluated, and the rate of release of macromol

Polyethylene tubes closed at both ends and with four perforations in the side walls were filled either with isologous muscle tissue or with formaldehyde-fixed or glutaraldehyde-fixed isologous tissue, and then implanted subcutaneously in rats. As con

Root canal length was measured in an experimental model composed of the severed halves of porcine mandibles, using an electronic device for locating the apical foramen. The measurements, each taken independently by two or three observers, were compar

The review presented here covers metastatic local and systemic disease secondary to the accumulation of plaque or the formation of other pathogenic microbial depots in the mouth. At least 3 pathways may link oral infection to secondary disease, to wi

Standardized specimens of young, autologous connective tissue were implanted in rabbits. The changes occurring in the implants were followed, and the reactions of the draining lymph nodes were studied by using light microscopy and immunofluorescence

The action of endotoxin on subcutaneous connective tissue was examined in an experimental model simulating the dental root canal. The local Shwartzman reaction was used as a tool to detect slight tissue alterations that might otherwise go unobserved.
