On the Densest Packing of Polycylinders in Any Dimension.

Using transversality and a dimension reduction argument, a result of Bezdek and Kuperberg is applied to polycylinders, showing that the optimal packing density of [Formula: see text] equals [Formula: see text] for all natural numbers .

The labial endodontic access: a rational treatment approach in anterior teeth.

Labial endodontic access is an alternative to the conventional lingual endodontic access in permanent teeth. The labial approach facilitates visibility and provides direct access to the root apex. Current restorative procedures offer improved methods to overcome the esthetic impairment resulting from this approach.

A prosthesis fabrication technique for the edentulous maxillary resection patient.

A technique for making final impressions, registration of jaw relations, and positioning of anterior teeth with the same record bases during the fabrication of an obturator prosthesis is described. By using this technique, a more predictable result may be attained with respect to jaw relations, obturator height, and lip position, all of which may be compromised in the edentulous patient with a postsurgical maxillary defect.

Assessing the dental treatment needs of an adult Israeli military population.

The dental treatment needs of an adult population (career army personnel, Israeli Defence Forces, aged 20 to 46) were determined. A method is described for quantitating total restorative, endodontic, oral surgical, periodontal, and prosthetic treatment needs. The amount, and in some categories the complexity, of treatment required per person increased in proportion to age.

A new type of mobile dental clinic developed following the Lebanon War, 1982.

A two-tier emergency dental services delivery system was developed following the October 1973 War, based on large mobile dental clinics (definitive restorations) and portable field units (emergency treatments). The increased demand for definitive restorations at the front lines, the mountainous terrain, and the extreme climatic conditions encountered during the Lebanon War, 1982, necessitated the development of a third alternative. A standard, compact module, either truck-mounted or helicopter-lifted, was outfitted as a fully equipped dental clinic according to Dental Corps specifications.
