COSMETIC DENTISTRY: The Two-Step Approach for Minimizing Excessive Gingival Display; Correct esthetic proportions are the foundations for successful results; however, other factors, such as the extent of gingival display while one is smiling, are important as well. The article describes a simple, two-step approach for minimizing gingival display when the basic esthetic proportions are correct. The first step is surgical crown lengthening, the second shortening incisal edges. Emphasis is on sound biologic and mechanical principles.

COSMETIC DENTISTRY: Adhesive Dentistry in the New Millennium; Advances in adhesive technology have occurred at a remarkable pace over the past 10 years. It seems as though every month brings a “new” and “better” bonding system onto the market. Clinical protocol is constantly changing. Just when clinicians have mastered one technique, they find it has been supplanted by another. This often creates confusion and suspicion on the part of the dental practitioner. There are, however, some fundamental concepts and principals applicable to all adhesive systems. This paper attempts to present a lucid and comprehensible review of some of these concepts. More importantly, how we can apply these concepts to the practice of clinical dentistry. Many of the latest innovations, such as one step systems and self-etching primers, are discussed. This paper is by no means intended as a comprehensive review of all aspects of adhesive dentistry. It is my hope that readers will come away with a basic understanding of where we are, and may be going, in the constantly evolving field of adhesive dentistry.
