Oral findings in glassblowers.

Oral changes related to the occupation of glassblowing have been examined in 74 Danish glassblowers, consisting of 44 active glassblowers (Group 1) and 30 past glassblowers (Group 2). In addition, 15 non-glassblowers (Group 3) were examined. All three groups worked in the same department of mouth-blown glassware in Holmegaard's Glassworks. White patches of the buccal mucosa occurred in 23% of active glassblowers, but did not occur among past or non-glassblowers. Histologically, the white lesions revealed morsicatio buccarum-like changes. The lesions are reversible and should be distinguished from leukoplakias. The term "glassblower's white patch" is suggested. Furthermore black discolorations of vermillion border and front teeth occured in 30% and 62%, respectively, of active glassblowers. Tooth fractures, mostly enamel fractures, caused by the blowpipe were found in 43% of active glassblowers and 19% of past glassblowers.

Aesthetic treatment of discoloration of nonvital teeth.

Attempts to treat discoloration in nonvital teeth were first reported a century ago. This article discusses two potential causes of nonvital tooth discoloration-trauma and endodontic treatment-along with a step-by-step clinical procedure for treatment of the discoloration. In trauma, hemoglobin is released into the tissues; iron oxides, formed by oxygen and iron in hemoglobin, cause discoloration and swelling that infringes on pulp space, forcing the pulp to recede with a potential loss of tooth vitality. After endodontic treatment, either hemorrhaging, materials used, or incomplete removal and breakdown of necrotic tissue may cause staining. The learning objective of this article is to review the causes and the prevention/treatment of discoloration in nonvital teeth.

Zirconium oxide post and core system for the restoration of an endodontically treated incisor.

Due to their enhanced optical properties (eg, translucency, value, chroma), ceramic systems can provide natural aesthetics for restorations placed in the anterior segment. In endodontically treated teeth with stained dentin, however, the use of translucent ceramic materials may be contraindicated unless the underlying discoloration can be masked. This article describes the use of a zirconium oxide post and core system with an all-ceramic crown for the restoration of an endodontically treated anterior tooth. This contemporary system allows optical and mechanical requisites to be resolved simultaneously.

Single anterior tooth restoration using a self-etching adhesive system and a reinforced microfill composite.

Treatment for a single discolored anterior tooth may involve placement of a direct composite veneer to enhance a patient's smile and mask underlying discoloration. Among the challenges clinicians may face in this endeavor are the selection of suitable composite materials, application of an adhesive bonding system, and re-creation of the natural shade variations inherent in natural teeth. This article discusses the characteristics and placement protocol for a recently introduced self-etching adhesive system and a reinforced microfill composite when they are used to restore a single discolored central incisor.
