[Electromyographic and computerized magnetic gnathokinesiographic studies of normal subjects].

The authors used electromyographic and computerised magnetic gnathokinesiographic equipment to examine habitual mastication and electromyographic activity of the masseter and anterior temporal muscles in two subjects with complete dentition, physiological functional occlusion and with no history or clinical records of cranio-mandibular disorders (CMD). The results obtained show the presence of common models of masticatory movement and electromyographic activity which conform to previously published data.

[Electromyography and computerized magnetic gnathokinesiography in the diagnosis and therapy of craniomandibular disorders].

The paper describes the material and methods used to examine two subjects with cranio-mandibular disorders (CMD), one of a predominantly articular type and the other of a prevalently muscular type. Both patients presented significant and specific alterations of masticatory movement and electromyographic activity before treatment, and this enabled a differential diagnosis between the articular and muscular forms of CMD to be made. On the contrary, at the end of definitive occlusal treatment, kinesiographic and electromyographic parameters in the two subjects were normal and physiological, thus confirming the resolution of clinical symptoms.

[A clinico-statistical study of the anatomico-clinical and immunohistochemical correlations in chronic lesions of the oral cavity].

A series of 191 biopsies of the oral cavity (epulides, cysts and granulomas) carried out in 1975-76 (104 cases) and 1985-86 (87 cases) is reported. Data regarding age, sex, site, histopathological diagnosis, dimensions of the lesions and type of operation were processed on an AT mod 280 computer in a file specially created using an Ashton Tate DB 111 Plus. Percentage values relating to epulides proved substantially unchanged. Those regarding cysts showed a particularly evident increase in males, while those relating to granulomas showed a decline in both sexes. From the immunopathological viewpoint, angiomatous epulides, prevalent in the female sex, presented a structural framework different to that of plasma cellular epulides, testified by the presence of vessels lined with endothelia reactive to fucose and with scanty plasmocyte immunoglobulin component.

[Dimensional stability of impression materials studied with Talysurf 10].

The dimensional stability of certain modeling elastomers was investigated. In order to obtain a complete picture, 2 samples of each elastomer class on the market (polysulphuric, polyether, silicone additives, condensation silicone), a total of 8 products, were tested according to the criteria outlined in ADA 19. In contrast with ADA 19 recommendations, measurements were taken using a Talysurf 10, a roughness meter that can also check for straightness, which was chosen as being equally efficient as other methods while offering highly reliable objectively verifiable data.

[In vitro enamel fluoridation using an ultraviolet laser].

28 samples of human enamel have been studied in order to measure fluoride absorption after treatment with ultraviolet radiations. Samples treated with topical application only presented limited fluoride absorption in enamel surface (up to 0.5 microns deep). The absorption rate was higher, using an U.V. lamp. In samples treated with "excimer" laser, fluoride absorption was much higher in the surface layer and occurred also deeper (3 microns).
