Cosmetic or esthetic dentistry?
This article, through presentation of case studies, defines differences and suggests separate definitions for the terms cosmetic dentistry and esthetic dentistry. Dentistry strives to emulate harmonious form and function for therapy, and modification of appearance is an integral part of dental treatment. Cosmetic dentistry suggests a certain accommodation and is a compromise of current technology. Cosmetic dentistry is commonly selected as an interim procedure that does not necessarily function ideally and does not always emulate the pristine state of a natural dentition. Esthetic dentistry requires less accommodation, incorporates acceptable biologic technology for long-term survival, functions suitably, and mimics the pristine state of the natural dentition. Cosmetic and esthetic dentistry are different in definition, concept, and execution.

Bond strength of photocured composite resin facings: clinical versus laboratory procedures.
The tensile strengths of laboratory versus clinical photocured composite resins have been investigated. Metal surfaces were bonded to photocured composite resin by either retentive beads, Sebond or Silicoating. The bond strengths were measured by an Instron machine and the fracture sites observed. Following repair with the adhesives Dentacolor Opaquer, Fusion and Cover up 2, the Instron measurements were repeated. The metal/facing bond strength was the highest in samples fabricated by the Silicoating technique, the bond strength exceeding the cohesive forces in the composite resin facing. The tensile strengths of metal/facing bonded by Sebond and retentive beads were similar. Fractures that include the facing and partially reveal the metal are the least resistant to tension after repair. Renewal of the Opaque layer and completion of the facing is superior to any of the repair methods used in this paper. The original fracture point is the weakest after repair. All the repair kits tested were inferior to the original restoration materials.

Fourth molars: a clinical study.
Supernumerary teeth may be found in both the primary and permanent dentition, although they are more common in the permanent dentition. Presence of a fourth molar is rare, and such a tooth is almost invariably impacted. Dental practitioners should be aware of the possibility of encountering this rare supernumerary, its diagnosis and treatment. The authors of this article conducted a survey of patients in Montreal, looking specifically at the prevalence, aetiology, diagnosis, pathology and treatment of fourth molars. Their findings are reported here, and compared with data from the literature over the past 15 years.

Nifedipine-induced gingival hyperplasia. A comprehensive review and analysis.
A comprehensive review of the literature and analysis of the clinical history, mechanisms, pathogenesis, histology, and management of nifedipine-induced gingival hyperplasia is reported. A correlation to age, gender, drug, dosage, duration of drug therapy, location, and mode of treatment is discussed. The case report presented provides a model for management of nifedipine-induced gingival hyperplasia and other drug-induced gingival hyperplasia.

Pemphigus vulgaris in adolescence. A case presentation and review of the literature.
Pemphigus vulgaris, a chronic autoimmune vesiculobullous disease, affects people in their fifth or sixth decade of life. Involvement in adolescence is rare with only about 30 cases reported in the last 35 years. This article presents a case of adolescent pemphigus vulgaris in a 15-year-old girl with oral and skin lesions. The patient has been free of lesions with a maintenance dosage of 10 mg of prednisone every other day. The mean age of the 31 patients, including our patient, was 14 years. Skin involvement was reported in 87% of patients, oral involvement in 87%, and skin and oral lesions in 81% with oral lesions preceding skin lesions. Early diagnosis of adolescent pemphigus vulgaris is important to eliminate or reduce the severity of further intraoral or extraoral involvement. The term adolescent pemphigus vulgaris is suggested when the onset is between 12 and 18 years of age.

Clinical procedures in fabricating post and core restorations: case reports.
In this series of case reports, unusual clinical procedures in the implementation of post and core restorations are demonstrated and their difficulties are discussed. First a method for preparing an immediate post and amalgam core, while utilizing the provisional self-curing acrylic resin crown as a matrix for the condensation of amalgam, is presented. The second technique is the fabrication of a cast post and core restoration that fits an abutment root as well as the existing crown of a four-unit fixed restoration. The third case illustrates the clinical procedures involved in preparing an immediate post and core restoration through an opening in the crown, when the extended fixed restoration cannot be removed.

Clinically versus laboratory photocured facings.
Acrylic and composite resin facings may fracture or become detached from the metal framework. Insufficient retention, abrasion and trauma are among the causes of these phenomena. Clinical and laboratory techniques have been developed to fabricate facings by means of light-curing composite systems such as the Dentacolor (Kulzer, Inc.) system. The effect of different polishing methods, obtained in both techniques using the same material, was studied with SEM on samples. Finishing and polishing procedures were accomplished using fine finishing diamonds, diamond burs and sof-lex discs. Smooth and lustrous surfaces were obtained with finishing discs, in contrast to techniques using other finishing instruments. Little or no difference in surface texture was observed between samples finished by clinical and those finished by laboratory techniques.

Oral epidermolysis bullosa in adults.
A rare case of epidermolysis bullosa in an adult is reported and the English-language dental literature of the last 20 years is reviewed. Special dental management is suggested. Early detection because of potential malignant transformation is discussed.

Oral osteomyelitis: pre-AIDS manifestation or strange coincidence?
A bizarre and unexplained localized osteomyelitis was discovered in the mandible of an otherwise apparently healthy 36-year-old man. This strange oral manifestation was followed 2 years later by a diagnosis of Pneumocystis carinii pneumonia, which indicated full-blown AIDS. Could osteomyelitis of the mandible be an alarming oral manifestation of AIDS before the disease is manifested in other ways?

Implant-supported overdenture rehabilitation and progressive systemic sclerosis.
Progressive systemic sclerosis, or systemic scleroderma, is an autoimmune multisystemic disease associated with vascular abnormalities, connective tissue sclerosis, atrophy, and autoimmune changes. The complex oral problems that may develop in patients with the disease and the difficult oral access necessitate extreme care in preventing dental disease. The oral management of a patient with an edentulous mandible and progressive systemic sclerosis, using an overdenture supported by osseointegrated implants, is presented and discussed.
