[The role of stabilometry in assessing the correlations between craniomandibular disorders and equilibrium disorders].

We examined three groups: 29 patients suffering from balance disorders and craniomandibular disorders but from vestibular disease; 21 patients suffering from balance disorders, craniomandibular disorders and vestibular disease; 26 patients suffering from craniomandibular disorders but not from vestibular disease or balance disorders. All cases were examined by the odontologist and otoneurologist and tested by computerized stabilometry; they were reexamined after six months of therapy by an occlusal stabilization splint. The static analysis of the results show a significative reduction of the postural oscillations in all patients.

[The use of computer-assisted stabilometry in the diagnosis of craniomandibular disorders].

The aim of this study was to evaluate the influence of the cervical region and the stomatognathic system on the balance control. We examined 35 healthy subjects and 201 balance disorder patients; of the 201 patients 60 suffered also from craniomandibular disorders (CMD) and 40 from cervical rachis disease. All cases were tested by computerized stabilometry executed in Romberg position: with closed eyes, retroflexed head and two cotton roles between the dental arches.

[Biochemical study of the dental pulp in the calf].

A biochemical study of dental pulp of calves has been performed concerning: a) peroxydability b) A, E, C vitamins content c) glutation (GSH) content d) presence of paramagnetic compounds e) phosphorylation ratio The dental pulp from incisors of 5-months-old calves has been preserved. Immediately after decapitation the pulp was immersed in liquid nitrogen. Chromatographic (HPLC) and spectroscopic (NMR-ESR) techniques have been used.

[Handicapped patients. General anesthesia or sedation?].

The Authors consider the problems involved in dental treatment of the handicapped patients. Accuracy in diagnosis of the handicap factor, knowledge about its consequences on pathophysiological status and about chronically assumed drugs are the first step: in fact these patients may be affected by a wide variety of physiopathologic and mental diseases. Failure of cooperation requires general anesthesia or sedation techniques.

[Morphological research on the dental pulp of the calf].

Morphological researches have been carried out through histological studies with fine and semifine sections at the electronic scan microscope on the dental pulp of calves. The general aim was to identify the antioxidant properties of pulp and study cellular density and microfibrillar architecture. The dental pulps of calves of 5-6 months taken immediately after slaughtering were used with immersions into the fixing liquid.

[Evaluation of fluoride content in Modena water].

The Authors confirm the importance of fluoroprophylaxis in the prevention of Dental caries. They analyze the main methods of fluoroprophylaxis pointing out the systemic fluoroprophylaxis, effected by means of water fluoruration, as the best one for a valid prevention of dental caries on a large scale. In view of such a kind of fluoroprophylaxis in our country the Authors considered quite interesting to effect a research about the amount of fluoride in the waters of the district of Modena.

[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).
