Rhythmic variations of P100 component of pattern-reversal visual evoked potentials.

Pattern-reversal visual evoked potentials (EPs) were recorded in seven adult subjects to assess the existence of rhythmic variations in processing visual information at a primary stage. During a session of two hours, sixty EPs were recorded on the left and right cerebral hemispheres. The amplitude of N75-P100 component was measured. Remarkable variations were found with a periodicity from 15 to 60 min in six out of seven subjects. No hemispheric differences were found in the rhythmic variations. The results are in agreement with the behavioral data which show ultradian variations in visual performance depending on a general activation oscillator.

[Deciduous dentition and orthognathodontic prevention. 2].

One of the main factors in the prevention of malocclusion is the preservation of healthy primary dentition until the time of normal shedding. By this contribution the Authors describe the restorative procedures and the pulp and canal treatments to be applied in deciduous dentition as well as the clinical and therapeutic problems connected with the early loss and the abnormal persistence of deciduous teeth. These therapeutic measures, in addition to caries prevention, have a very important role in the promotion of the normal development of occlusion.

[Role of the lip-bumper in nonextraction orthodontic therapy: clinical-statistical study].

The purpose of this study is to investigate the morphologic and dimensional changes of lower arch that might occur in patients undergoing treatment with the lip-bumper. After a brief examination of the clinical applications of lip-bumper, we report the results of a research concerning 20 children in the mixed dentition period. The effect of this simple orthodontic appliance has been an expansion of the mandibular dental arch, with a real increase of arch length and transverse dimension. Therefore the lip-bumper can be used in non-extraction treatment of malocclusion, in order to obtain a space recovery in lower arch.
