A technique for using flowable composite resin for making interocclusal records in cases involving fixed prosthodontics is described. The precise relation of maxillary and mandibular casts is an essential step in developing accurate occlusion in fixed prosthodontics. This technique consists of direct intraoral fabrication of transfer copings and an interocclusal record using flowable, light-activated composite resin. The technique is simple, does not require advance preparation and can be done during the final impression appointment

Oral mucosal desquamation is a common manifestation of a number of pathologic conditions. The differential diagnoses may range from chemical and electrical burns to conditions such as allergic reactions, hormonal disorders, and mucocutaneous conditions. This article reports two cases of oral mucosal reactions that became a diagnostic challenge at the time of examination. Both subjects had chronic extensive desquamative stomatitis and gingival ulcerations. Following a careful review of their medical and dental history, the use of oral health care products was projected as a possible cause of their mucosal condition.

This case report describes severe mucosal injuries following misuse of an undiluted over-the-counter mouthwash with a high alcohol content (70%), oil of peppermint and arnica. The mouthwash was to be diluted 5:1 with water. The patient used undiluted solution to better treat her self-diagnosed "contagious gum infection." She experienced burning sensation with each rinse and developed severe mucosal injuries subsequently. Her oral condition improved within 48 hours following discontinuation of use of the mouthwash and application of a mixture of Benadryl Elixir, Maalox Plain, and 2% viscous Lidocaine. A detailed history and review of a patient's medical condition will help to differentiate self-induced mucosal injuries from those caused by an allergic reaction or skin diseases.

Autoimmune progesterone dermatitis is a rare clinical condition associated with variable cutaneous and mucosal eruptions such as urticaria, erythema multiforme, and eczema. Exacerbation is influenced by hormonal changes of the menstrual cycle. The patient described in this report had recurrent cyclic lesions on the skin, oral mucosa, and lips that appeared just before regular menstruation and persisted until a few days after. During each cycle, the eruptions appeared at the previously affected sites, mimicking the clinical feature of a fixed drug eruption. This rare phenomenon is attributed to an autoimmune reaction to female sex hormones. The condition failed to respond to therapy with prednisone, but improved with the use of an antiestrogen drug, tamoxifen. This medication suppresses ovulation and the post-ovulation rise in endogenous progesterone levels.

Gingival enlargement is caused by some local and systemic pathologic conditions. Clinical manifestations vary and depend on the underlying defects. Diagnosis of these abnormalities and their relationship to underlying systemic conditions is essential prior to establishment of any treatment. Several gingival overgrowth conditions resulting from various causes are included in this review. Some conditions are rare and appear with clinical features interesting to both dentists and dermatologists. A brief review of causes, pathogenesis, and differential diagnosis is presented.

Cutaneous vascular abnormalities are frequently detected on initial examination of newborns. Many of these lesions are common variations of normal lesions such as nevus simplex and strawberry hemangiomas. Some of the vascular abnormalities, however, are a feature of a number of syndromes with multisystemic involvement. These syndromes have been described under the heading of neurocutaneous diseases. Ataxia-telangiectasia is a neurocutaneous syndrome that appears with progressive cerebellar ataxia, oculocutaneous telangiectasias, and abnormalities of many other organs. Oral mucosa is also affected. Current concepts on the pathogenesis of ataxia-telangiectasia and one case of the disease are presented in this article.
