Oral lesions in psoriatic patients.

Psoriasis is a chronic, recurrent, inflammatory disease of the skin. The occurence of psoriatic lesions in oral mucous membranes is a subject of controversy, and some investigators have stated that such lesions do not occur at all. In the present investigation 100 psoriatic patients were examined for the presence of oral lesions. No patient exhibited oral lesions of psoriasis; however, there was a relatively high incidence of angular cheilosis (11 per cent), fissured tongue (6 per cent), and benign migratory glossitis (5 per cent). The possibility that benign migratory glossitis is an oral manifestation of psoriasis is discussed.

Hand, foot, and mouth disease.

Hand, foot, and mouth disease, also known as vesicular stomatitis with exanthem, is a vesicular disorder affecting both skin and oral mucosa. The disease is usually caused by Coxsackie virus A-16 and affects mainly children. The oral lesions may require differential diagnosis from other conditions, such as herpetic gingivostomatitis, aphthous stomatitis, and herpangina. Hand, foot, and mouth disease should not be confused with foot-and-mouth disease of cattle, which is rare in human beings and is not caused by Coxsackie virus.

Eosinophilic bodies in the epithelium of oral inflammatory hyperplastic lesions. Histopathologic and histochemical study.

Four hundred twenty-three specimens of inflammatory hyperplastic lesions of the oral cavity were examined for changes in the epithelium. Amorphic eosinophilic material was found in the superficial layers of the epithelium in 12 per cent of the cases. The incidence and severity of the changes were related to the intensity of the inflammatory reaction in the underlying tissue. Histochemically, the material contained protein, disulfide and sulfhydryl groups, tryptophan, and carbohydrate.

Taurodontism. Report of sixteen cases in Israel.

Taurodontism is generally considered a very rare dental anomaly in modern man. Sixteen new cases of taurodontism in Israel are described in patients presenting for routine treatment in a dental center. The majority of affected teeth occurred singly, and the mandibular second molar was the tooth most frequently involved. It would appear that taurodontism is a great deal more common than was previously thought. The clinical aspects of the condition are discussed with regard to endodontic and periodontal therapy.

Calcifying odontogenic cysts with intracellular amyloid-like material.

Intracellular deposits of amyloid as defined by positive Congo red staining with green polarization birefringence and standardized toluidine blue staining with pink-red polarization birefringence were observed in the epithelial lining of three cases of calcifying odontogenic cysts. It is suggested that this material is not true amyloid but, rather, a dengenerative product of the epithelial cells as has been described in calcifying epithelial odontogenic tumor (Pindborg tumor).

Roentgenologic study of the mental foramen.

Locating the mental foramen in periapical radiographs is of great clinical importance. One thousand full-mouth intraoral radiographs were examined, and the location of the mental foramen in both the horizontal and the vertical planes was registered. In the horizontal plane 70 per cent of the mental foramina were found to be located between the two premolars, and 22 per cent were in the apical area of the premolars. In the vertical plane the highest percentage of mental foramina was found to be located superior to the level of the apices of the premolars.

Amyloid-like material in odontogenic tumors.

Various types of odontogenic tumors (epithelial, mesodermal, and mixed tumors) were studied for the presence of amyloid material. Highman's Congo red and Wolman's standard toluidine blue methods were used for diagnosing amyloid. Of all types of odontogenic tumors studied, only the calcifying epithelial odontogenic tumors contained material that might be interpreted as amyloid-like.

Ultrastructural study of focal epithelial hyperplasia.

Biopsy material from two young Israeli patients with focal epithelial hyperplasia revealed acanthosis, papillomatosis, and the presence of many epithelial cells with a clear cytoplasm in the basale and stratum spinosum. Many of the inclusions seen with the electron microscope had the morphologic appearance of lysosomes, but definite identification must await cytochemical evidence.

In vitro cultivation of adult human gingiva I. primary epithelial outgrowth from gingival explants.

The in vitro behavior of human gingiva was studied using a simple tissue culture technique. Gingival explants from adult patients undergoing periodontal surgery were cultivated in three different media for periods up to three weeks. It was demonstrated that primary epithelial cell cultures can be obtained under simple and predictable conditions. The migrating cells were compact and uniform in shape and resembled the spinous cell layer of a squamous stratified epithelium. Mitotic activity was regularly observed all over the outgrowth, which continued to grow throughout the entire experimental period.
