A technique for fabrication of a model to aid in teaching surgical management and suturing is presented. The model, which simulates dentition, supporting periodontium, and gingival soft tissue, can be made inexpensively in a dental laboratory.

The choice of suture materials should be based on sound scientific knowledge. This concluding section of a two-part article discusses the use of nonabsorbable sutures and suture needles, and examines issues related to suture materials, such as suture diameter (gauge), tissue reactivity, knot and knot security, workability, and tensile strength.
Scanning electron microscopy was used to examine factory-sharpened, dulled, and resharpened scalers. The following observations were made: 1. The factory sharpened scalers exhibited metallic extensions from the lateral surface (wire edges). 2. The machine-resharpened instruments resulted in nonfunctional wire edges from the facial surface. Honing produced an exact meeting of facial and lateral surfaces. 3. Hand sharpening, using an Arkansas stone (grit 500) against the lateral surface away from the cutting edge, effected an exact meeting of the facial and lateral surfaces and no evidence of wire edges. 4. From this study an optimum cutting edge for a scaler is characterized as having a smooth, contiguous meeting of the facial and lateral surfaces free of wire edges. If a wire edge is present, it should be functional.
