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. Labial access is especially beneficial for patients with limited mandibular opening. Other indications are in Angle's class II division 2 dentitions or in teeth with resin-bonded cast restorations. Anatomic studies for the single tooth that corroborate the labial endodontic approach are reviewed.

Use of an Adams clasp for a cast unilateral removable partial denture.

A unilateral complete dentition with tight intercuspal contacts complicates the design of the interocclusal retentive elements of a cast removable partial denture. Use of an Adams clasp, which is connected to a predesigned retentive mesh in the metal framework, is suggested as a conservative and economical treatment option in this situation. Guidelines for minimizing the risk of breakage of the Adams clasp are presented.

Selective-pressure impression technique for nasal prostheses.

An impression technique for nasal prostheses that places pressure in the superior regions of the nasolabial sulci is described. The pressure is delivered through a U-shaped frame embedded within the impression. Better adaptation and camouflage of the finished prosthesis is achieved and the improved esthetics enhances the confidence of the patient using a nasal prosthesis.

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. The estimated time required per adult (all ages) to complete all dental treatments was approximately 10.5 h, including 1 h for dental hygiene therapy. These data permit calculation of cost and professional personnel needed to treat this population.

A technique for the fabrication of the open obturator.

Obturator prostheses are often large and heavy. As an alternative to a lighter hollow obturator, a technique for fabrication of the open obturator has been presented. Use of a removable silicone core facilitates processing, recovery, and polishing of an obturator that is open superiorly.

Prosthodontic management of postsurgical soft tissue deformities associated with marginal mandibulectomy. Part I: Loss of the vestibule.

1. Marginal mandibulectomy patients with a postoperative obliteration of the vestibule were treated prosthodontically in accordance with the "denture space" concept. 2. All patients presented displayed adequate form and function with the prostheses during a period ranging from 2 to 6 years without being subjected to preprosthetic surgery. 3. The most important factor when considering prosthesis stability is the interrelationship between form and function of the orofacial structures rather than the mechanical factors of maximal bone coverage by the prosthesis.

Prevalence of taurodontism found in radiographic dental examination of 1,200 young adult Israeli patients.

The prevalence of taurodontism was studied radiographically in 1,200 young adult Israeli patients. In order to differentiate taurodont teeth from normal teeth, three types of taurodontism (meso-, hypo- and hypertaudodontism) were defined in biometric terms, using radiographic features of molar morphology. All three types according to Shaw's classification were seen. Taurodontism was found to occur in 5.6% of 1,200 individuals and in 1.5% of the 10,204 molar teeth examined. The mandibular second molar was found to be the most prone, being involved in two thirds of all cases found. Hypertaurodontism was found only in three cases, in the third molars. The conditions was seen to involve single and multiple teeth, both unilaterally and bilaterally, with the latter being most predominant.

Preservation of occlusal vertical dimension in overdentures.

The preextraction record is used to reestablish the occlusal vertical dimension in immediate and in later overdentures. A colored dot on the denture can be used to verify the occlusal vertical dimension after the dentures have been inserted.

Taurodontism. Report of sixteen cases in Israel.

Taurodontism is generally considered a very rare dental anomaly in modern man. Sixteen new cases of taurodontism in Israel are described in patients presenting for routine treatment in a dental center. The majority of affected teeth occurred singly, and the mandibular second molar was the tooth most frequently involved. It would appear that taurodontism is a great deal more common than was previously thought. The clinical aspects of the condition are discussed with regard to endodontic and periodontal therapy.
