Volunteering in Dental Peer Review: Differences Between Volunteers and Practitioners at Large

This report characterizes dzfferences among early and late volunteers, and non-volunteers for personal characteristics and situational determinants of volunteering in an experimental dental peer review study. Differences were found jor volunteers/nonvolunteers for some items representing subject interest, expectation of a favorable evaluation, sociability, and achievement motivation.

Staining porcelain-bonded-to-metal restorations

Abstract Esthetic porcelain-fused-to-metal restorations are dependent primarily upon sound tooth preparation, careful color selection, and proper manipulation of materials. Discrepancies in color of porcelain fused to metal do occur. However, the use of stains can eliminate many of these deficiencies. Indications, techniques, and precautions in staining porcelain bonded to metal have been described.

Indirect technique for making porcelain inlays

Abstract An indirect porcelain inlay technique has been described whereby a new refractory investment eliminates the need for a rigid die and a platinum matrix. The simplicity of this procedure should place the porcelain inlay within the capability of any dentist who finds a need for this fine restoration in the treatment of his patients.

Indications and cavity preparation for porcelain inlays

Abstract Indications and cavity preparation for class III and class V porcelain inlays have been described. In addition, variations of these cavity preparations have been discussed. Because of the use of a combination of a refractory investment and elastic impression materials, the problem of placing durable and esthetic porcelain restorations in anterior teeth can be resolved with satisfaction.
