1. 1. Four paper points were used to wipe out and culture the root canals of each of 95 single-canal teeth. 2. 2. The quantitative effects on the culture samples were recorded. Comparisons were made regarding the following aspects of the quantitative effects: (a) variations in culture results in tubes from the same tooth, (b) variations in culture results from vital and nonvital teeth, (c) results of cultures in teeth with canals open to saliva, and (d) results of 48 hours' and 7 days' incubation. 3. 3. A comparison was made of the four culture points are analyzed (a) individually, (b) according to results of the first two points combined, and (c) according to results of the third and fourth points combined.

We have conducted an experimental study in which dentine disks and Whatman paper were used to test discoloring effects of disinfectants, antibiotics, and flushing solutions used in endodontics. Each of the chemicals was tested alone and in the presence of a 1 per cent suspension of human erythrocytes in saline solution. Polyantibiotic and disinfectant pastes were used as dressings on recently extracted teeth, which were then split open to show discoloration. The most severe discoloring action was exhibited by the two N2 pastes and by polyantibiotic pastes containing Terramycin and Declomycin.

The article presents research examining the culture broth contamination by residual paraaminotoluene sulfonamide (PATS) in endodontal therapy. Particular attention is paid to the relation between carry-over of residual medicament and culture growth inhibition when PATS is used as an endodontal antiseptic. Results found that endodontal bacterial growth was not inhibited in infusion broth where PATS concentration was as high as 10 mg.

A method for the isolation of anaerobic bacteria from endodontic specimens under Continuous anaerobiosis is described. A mobile anaerobe unit supplies a gentle stream of oxygen-free gas over the tooth when the bacteriologic sample is taken. The paper-points are then, under oxygen-free gas, immediately transferred to prereduced, anaerobically sterilized roll tubes. The different isolated anaerobic bacteria are typed with biochemical tests, antibiotic susceptibility testing and gas chromatographic analysis of volatile fatty acids and alcohols.

SILVER amalgam may be used for the obliteration of apical canals by a coronal approach, or for the retrograde settling of apical canals and for the repair of those accidental perforations of the root which allow adequate access for direct instrumentation. The technique of filling the apical third of a root canal with amalgam either before or after apicectomy has been fully covered in earlier publications (Messing 1958, 1960, 1965), but in this paper the methods used to prepare and fill perforations and apical cavities will be discussed, and the use of amalgam for sealing the apices of teeth destined for re-implantation will also be described.

An experimental study is described of the apex formation and structure in immature permanent teeth alter vital amputation, vital extirpation and after the treatment of teeth with necrotic pulp. Experiments in young dogs suggest that after vital amputation of the coronal part of the pulp, root formation was continued through the process of changed odontogenesis. In cases where the pulp had been completely extirpated or after the treatment of pulpless teeth, the process of normal odontogenesis was interrupted and the apex was completely closed by non-homogeneous vital calcified tissue. On the basis of studies of the structure of the calcified tissue, it was concluded that it was a product of the formative activity of cells originating from the successive differentiation of fibroblasts in the young granulation tissue. The experiments suggest that following vital amputation of the pulp in children, further root odontogenesis is possible. In the treatment of pulpless teeth, the basic target should be stimulation and preservation of the formative activity of the granulation tissue cells n the apical part of the root canal to allow the possibility of calcified callus forming in the wide apical opening.

Autografts were performed on rhesus monkeys. After standard endodontic procedures and reimplantation the monkeys were killed at one week intervals. Elastic, reticulin, collagen, and oxytalan fibers were studied histologically in the periodontal ligament and transseptal regions. Ankylosis and fiber degeneration may be related to the quality of the regenarted fibers and the lack of functional stimulation during fiber regeneration. [ABSTRACT FROM AUTHOR]

In odontometric studies, root divergence can be expressed in terms of the ratio of the projected root length to the actual root length (cosine) or as the actual angle itself. Since the distribution of the cosines is skewed and the distribution of the angles is rather symmetrical, the angle measurement is preferable. Various types of significance tests with either measurement will generally not differ greatly, because of the insensitive (robust) nature of these tests. [ABSTRACT FROM AUTHOR]

Without a stop to control the depth of pene tration of the root canal file in the canal dur ing endodontic treatment, periapical irritation and an overfilled canal that may not be her metically sealed may result. The new stop discussed in this paper and the new point of reference, the floor of the pulp chamber, en able the dentist to use standardized instru ments with greater accuracy, efficiency, and convenience. Successful endodontic treatment demands respect of the periapical tissues during biomechanical in strumentation and a properly prepared canal to receive the filling material. There have been many attempts to develop a stop to control the depth of penetration of the root canal file in the canal. This paper describes a new concept that uses the pulpal floor of the chamber as a point of refer ence and a new stop developed as a result of thig concept. The importance of the root canal instrument stop in endodontics has been well established. Many types are in use today, indicating its im portance and the fact that a stop has not been developed to satisfy most dentists. Root canal stops in use need perfecting be cause they are bulky and cumbersome; adjust ment of the depth of penetration is time-consum ing; the dentist’s vision is usually obscured, and his tactile sense is impaired; the predetermined depth may change while the instrument js in use; most root canal stops are expensive; some are difficult to sterilize properly; some can be used only on the anterior teeth, and all root canal stops

Some of the presently available root canal medicaments were studied with the hope of combining and altering them so as to retain their antimicrobial activity while reducing their inflammatory potential. In the laboratory phases of the study, antimicrobial activity was measured by means of the filter-paper disk technique. The rabbit eye was used in tests for inflammatory potential. The following compounds and combinations were tested in both the laboratory and the clinic: (1) dichlorophene, (2) hexachlorophene, (3) camphorated monochlorophenol, (4) hexachlorophene plus camphorated monochlorophenol, (5) thymol 5 per cent plus camphorated monochlorophenol, in equal parts of Xylocaine ointment, plus hexachlorophene 1 per cent. The last combination seemed to have the most desirable properties of all the compounds tested. It had excellent antimicrobial activity; it was almost completely free of inflammatory potential when tested in the clinic and in the rabbit's eye in the laboratory; it had excellent residual activity in the root canal; and it was easy to use.
