1. 15 patients, whose therapy with the anticoagulant Coumarin was not discontinued, were observed for bleeding following dental extractions. 2. There was no significant bleeding in these patients as compared to 15 others whose Coumarin therapy was temporarily interrupted. 3. Patients with prosthetic heart valves should preferably be hospitalized for dental extractions. but Coumarin/anticoagulant therapy need not be discontinued. The procedures can safely be done within a therapeutic range of 20-30% P.T.

The bending strength of heat-cured resin samples was found to be 49% higher than that of autopolymerizing resin samples cured under room conditions. Curing the latter resin in a pressure vessel at 32psi and 30 degrees C increased its strength by 4.5%. For this reason and because a less porous material is obtained, pressure-curing may be employed with advantage for the preparation of various appliances from S.C. resin. The effect of pressure-curing in increasing the strength of the repaired samples was not significant. It would also appear that pressure affects the porosity of small quantities of repair material less than when appliances are made from S.C. resins only. The increase in strength achieved by pressure-curing repairs, in which only small quantities of S.C. resin are used, is therefore questionable.

Cores, dowels and pins provide retention and support for restorations and protect the residual tooth substance. Their use is essential in restorative dentistry.

A method of temporary permanent splinting has been presented which enables the clinician to stabilize anterior teeth aesthetically and rigidly without resorting to cast restorations. The method utilizes an acid-etch composite technique with T.M.S. Pins and has shown itself to be a rapid, cosmetic and durable alternative to either the temporary intra-coronal wire ligation or the more permanent gold prosthesis.

Pulp exposure remains a source of great frustration to the dental practitioner, because the outcome of any pulp capping procedure is marked with uncertainty. The clinician is often unaware of the coexistence of possible pulp pathology at the time of damage to the pulpal wall. Until a more accurate clinically and histologic diagnosis can be made, pulp capping as a clinical treatment, can only be rendered on an empirical basis.

The purpose of the present study was to obtain current information regarding periodontal diseases. The study was conducted in Israel among ninth to twelth grade students, 14 to 18 years of age, residing in Jerusalem, Tel Aviv and Ramat Gan. A total of 725 school children were examined. During the examination only periodontal status was checked. Periodontal status was recorded according to Russell's Periodontal Index (PI). The mean PI found was 0.52. The results indicate an increase in the mean PI with age. Significant difference was found in the mean PI values between girls and boys. Girls constantly scored lower mean PI values than boys. No significant differences were found in the mean PI scores when studied according to country of origin.

Denture-induced changes of the oral mucosa comprise, besides denture stomatitis and inflammatory papillary hyperplasia, the so called folds and redundancies in sulci and flabby ridges. The present article deals with these two tissue reactions which are associated with chronically ill-fitting dentures.
