[Cervical trauma in the pathogenesis of cranio-cervico-mandibular dysfunctions].

A sudden cervical extension-flexion (whiplash) can cause a temporomandibular pathology with a direct and indirect mechanism of action. A total of 24 patients of both sexes who had undergone acute cervical trauma, which had led to masticatory dysfunction of a meniscal or algomyo-facial type, were examined. The most frequent signs and symptoms were regional pain, a qualitative and quantitative change in movements, cephalea, and articular noise. A complete condylo-meniscal block was observed in three cases. Concomitant radiographic tests using a trans-cranial projection confirmed clinical findings. A multidisciplinary individual therapeutic approach ensured complete functional recovery; prognosis varied with regard to cephalalgia which is related to the individual's psycho-behavioural substrate. The paper stresses the importance of early diagnosis and targeted treatment in order to prevent symptoms from becoming chronic thus making the disorder a disability which is difficult to treat.

[Correlation between serum glutathione reductases and bone densitometry values].

Free radicals, because of their marked chemical activity, have often been found to be involved in many human diseases. Enzymatic antioxidant systems, namely glutathione-reductase, present both in red blood cells and in serum, have been demonstrated to play a key role as free radicals scavengers. The present work has been carried out in order to evaluate the possible role played by free radicals in the demineralization process of the bone matrix. Glutathione-reductase activity, assayed by a slightly modified Horn's method, was related to bone density measurements. All the subjects with reduced densitometric values showed reduced glutathione-reductase levels. Our results seem to support the hypothesis of a strict relationship between low activity of antioxidant systems and demineralization process of the bone, in consequence of enhanced free radical levels.

[Morphology of the upper arch in unilateral posterior crossbite].

The Authors have studied 81 patients, age 4 to 14 years, who exhibit unilateral posterior cross-bites. In the study it was found that the morphology of the maxillary arch can be symmetrical, contracted or expanded on the side of the cross-bite. Of the symmetrical maxillary arches, 79.3% occluded with a mandibular arch on symmetrical bone. Of the arches constricted on the side of the cross-bite, 81.0% occluded with a mandibular arch on asymmetrical bone. Of the arches expanded on the side of the cross-bite, 81.0% occluded with a mandibular arch on asymmetrical bone. From this study we can also say that it is possible to obtain diagnostic data concerning the morphology of the mandibular bone from the morphology of the maxillary arch. Statistical analysis of these data reveals this to be particularly true when the maxillary arch is expanded on the side of the cross-bite.

[Vertical dentobasal changes induced by the lip-bumper: clinical study].

37 patients aged between 8 and 11 years old, were treated with the application of a lip bumper in order to explore the effects on the lateral sites after 1 year of treatment. Patients were been divided into two groups, depending on age (8-9 and 10-11) subdividend depending on typology and compared with similar control group. After one year the dental basal height was measured and resulted to be 0.90 mm higher in treated patients than in the control groups.

[Morphology of the cranial base in a group of Campania school children].

The A.A. analysed the cranial base morphology on 14 school-children in the eastern part of Naples, to establish if the most used cephalometric values were useful for Campanian people. The values found out resulted superimposed to those referred in the considered analysis.

[Medico-legal aspects of orthodontics].

The deep technological innovations undergone by the medical profession, the changed relationships between physician and patient, the ever-growing attention given by public opinion to sanitary problems, as well as the growing expectation for the positive results of all me actions have determined, specially in these last years, medico-legal problems connected to the different spestic medico-surgery activities, so that also the ortodo is called to a constant comparison not only with ethical deontological problems, but with the juridical ones too.
