[The importance of direct immunofluorescence in the diagnosis of oral lichen planus. A clinical study and proposal of new diagnostic criteria]

A series of 40 lesions of various kinds as lichen planus are examined using samples stained with trichromic test. HLA-DR expression with immunoperoxidase technique and direct immunofluorescence using the standard techniques. The aim of the study was to discover the usefulness for diagnosis of direct immunofluorescence, above all in histologically uncertain cases. The results suggest the view that direct immunofluorescence is essential for diagnosis of lichen planus, in all clinical aspects. The author concludes with description of clinical proceeding for differential diagnosis between white and erosive lesions of mouth.

[Cyclosporin in a bioadhesive formulation in the therapy of oral erosive lichen planus. A clinico-experimental evaluation]

This study illustrates the possible topical therapy of OLP with cyclosporine A under bioadhesive gel formula. The treatment was carried out on 6 patients for 8 weeks in much lower (48 mg/day) than those used by other authors. The novelty of this study lies in the use of a bioadhesive formula with carbosymethylcellulose which allows CsA to remain on oral mucosa for about two hours. The remarkable results have shown a reduction ranging from 50 to 80% of oral lesions, thus proposing its specific use in all the forms resisting usual therapy.

HLA-DR expression with immunoperoxidase technique and direct immunofluorescence using the standard techniques. The aim of the study was to discover the usefulness for diagnosis of direct immunofluorescence, above all in histologically uncertain cases. The results suggest the view that direct immunofluorescence is essential for diagnosis of Lichen planus, in all clinical aspects. The author concludes with description of clinical proceeding for differential diagnosis between withe and erosive lesions of mouth.

[A proposal of a new histological method for the dynamic diagnosis of the disease stage in oral lichen planus]

The paper describes a histological fixing and staining technique capable of identifying the stage of disease in oral lichen planus. This is based on staining the nuclei on the basal stratum blue instead of red-orange as normally occurs using Mallory's technique. Under particular conditions of increased cellular protein synthesis these become a typical blue colour.

[The pathogenesis of lichen planus. Experimental research on the significance of HLA-DR antigenic expression by keratinocytes]

The incidence and distribution of keratinocytes expressing the major histocompatibility complex antigen HLA-DR were determined in lesions of oral lichen planus. The authors examine the condition, but its functional significance remains unknown.

[Class II cavity for amalgam. Proposed new modifications related to material characteristics]

The Authors study conservative preparation designs for Class II amalgam restorations, with and without an occlusal dovetail. They propose the use of a high-copper filing admix allow in Clas II preparation with occlusal dovetail and the use of high-copper spherical alloy in box only restorations.

[Experimental verification of the content of premeasured capsules of four different dental amalgams]

The Authors examine the problem of exactness of measure of weight in amalgam capsules and precision of ratio metallic powder-mercury. They study four materials and in some cases they found big want of precisione in dosing of capsules.

[Regeneration of old gutta-percha cones]

Aged gutta-percha filling cones become brittle and unsuitable for use; a technique was published for reducing their fragility, thus "rejuvenating" them. The Authors study this technique in five different cone brands, but only 30% of cones made usable.

[Oromaxillofacial teratogenic effects of heavy and light drugs]

Effects of drugs administration on the growth and development of the cervical-maxillar-facial region were studied. Drugs as ASA are possible etiological factors in embryo-fetal deaths and fetal facial malformations in animals.

[Principal immunohisto-chemical methods applicable to oral biopsies]

The AA. describe the most commonly used immunohistochemical techniques and their applications, discuting the problems relating to retention of tissue immunoreactivity and specificity of mono- or poly-clonal antibodies.

[The immunological basis of vaccine prophylaxis of carious disease. Maternal-fetal relations. Defense factors specific to the host]

The authors discuss of the relation between mother-phoetus from an immunological point of view and the real protection at birth because of the passing through the placental philter of maternal immunoglobulins. Then the Authors discuss of oral tolerance and of the possibilities of administering by oral-enteric way and the immunity of the guest.

[Immunoprophylaxis of carious disease. Historical outline, location of research groups, current status of anticaries vaccine use]

The authors after giving some historical hints of vaccino-prophylaxis outline the various attempts made during the last twenty years, the present situation and the actual risks connected with the ways of administering of the antigen, in case of vaccination from a "public-health" point of view.

[Prophylaxis of carious disease. Outline of dietetic and pharmacological prophylaxis]

The authors schematically describe the possibility of specialistic sanitary intervention in prevention, primary secondary and tertiary. They, furthermore, discuss of the real possibility of dietetical and pharmacological prophylaxis with special regard to the proper use and on the mechanism of action of fluorine and other chemical antiplaque agents.

[Hyperbaric oxygen therapy in the treatment of osteoradionecrosis: a review of its use and efficiency]

In this work, the AA. speak of the use of hyperbaric oxygen therapy in the treatment of osteoradionecrosis, with particular reference to enforcement of this therapeutic technique in the mandibular necrosis caused by irradiation of tumour of cervical-facial region.

[Gingival hyperplasia associated with the therapeutic use of nifedipine: review of clinical cases]

The AA., starting point for some clinical cases occurred to their observation, deal with gingival hyperplasia by calcium-antagonists, showing that, not with standing the unlike aetiology, the clinical and histological picture is like the anticonvulsive or immunedepressor gingivitis.

[Marcus Gunn phenomenon. "Jaw winking"]

The A.A. describe the clinical characteristics of the Marcus Gunn phenomenon, and delineate the main etiopathogenetic hypotheses, as well management therapeutics.

[Burning mouth syndrome]

The analysis of etiopathogenetic and clinical aspects of burning mouth syndrome, allow to suppose the participation of more factors in the determinism of disease. Consequently, also the therapy, might to require the presence of many specialist.

[Orofaciodigital syndrome]

The AA. behaving the orofaciodigital syndromes, describe the main peculiarity of the etiology, anatomo-pathology, clinical features, diagnosis to the light of the late acquisitions about these.
