Herpes zoster infection as a differential diagnosis of acute pulpitis.

Many diseases can cause orofacial pain, and the diagnosis must be established before final treatment. This case report presents a patient with orofacial pain that was diagnosed as an acute pulpitis. However, there was no evidence of this problem on examination. After 4 days, the patient showed multiples vesicles on the face, and a herpes zoster viral infection was diagnosed. The patient was treated with acyclovir and, after 2 yr, she still complains of facial sensitivity.

Laminin and collagen IV distribution and ultrastructure of the basement membrane of the gingiva of the rat incisor.

The continuous growth of the rat incisor is associated with renovation of the junctional epithelium and resorption of the periodontal ligament. The circumdental papilla separates the connective tissue suffering resorption from the rest of the gingiva. Laminin and collagen IV were detected by the immunoperoxidase technique on the basement membrane of all regions of the gingival epithelium of the rat incisor, except the internal basal lamina and the internal surface of the circumdental papilla. The internal basal lamina is formed by a granular electron-dense material, without the organization of a typical basal lamina. Areas of the internal surface of the circumdental papilla, negative for laminin and collagen IV, lack the basal lamina. These data suggest that these molecules are not components of the dento-epithelial junction of the distal surface of the rat incisor. In addition, the basal lamina is absent or fragmented on the internal surface of the circumdental papilla, adjacent to the areas of the connective tissue undergoing resorption.

Oral mucosal health and disease in institutionalized elderly in Brazil.

During the last decade, many studies in Europe and North America have evaluated oral conditions and dental needs in the elderly. Similar information does not exist in Brazil. The aim of this study was to determine the prevalence of oral health and disease in elderly persons living in an institution in the city of Piracicaba, State of São Paulo, Brazil. Of 350 elderly persons, 134 males and 136 females were interviewed and clinically examined. Less than one half had healthy mouths. 58.9% of the examined individuals showed one or more lesions in the oral mucosa, the most frequent being denture-induced stomatitis (20.0%). Fibrous hyperplasias (11.8%) and angular cheilitis (9.3%) were fairly common. Gender, use and degree of hygiene of the denture were factors statistically significantly contributing to prevalence of denture stomatitis. Precancerous lesions such as leukoplakia (3.0%), actinic cheilitis (2.6%) were uncommon but three cases of squamous carcinoma (1.1%) were revealed. This study emphasizes the need for regular oral examinations of the elderly by personnel trained in oral diagnosis.

[Denture stomatitis--presence of bacteria and yeasts].

The presence of yeasts and bacteria was studied in 26 patients with denture stomatites, and the results compared with the data of the normal mucosa foi edentoulous patients, who used or not upper dentures. The use of dentures caused an increase in the amount of yeasts, and there was a correlation with the severity of the stomatitis. Gram positives cocci and bacilus predominated in all studied groups, but in cases of stomatitis there was an increase in the amount of Gram negative cocci and filamentous. These results suggest that besides yeasts, modifications of the bacteria flora can be relevant for the development of denture stomatitis.
