Due to high cariostatic activity, glass ionomer are irreplaceable component in restorative armamentarium. Clinician needs to stock several types of material since characteristics (film thickness, radiopacity, viscosity, colors, ecc.) are adapted for specific uses.
This study reports the results of the evaluation after three years of total amalgam restorations, made on molars and premolars vital and devitalized. The clinical parameters examinated were: 1) anatomic form and axial contour 2) marginal integrity 3) recurrent caries 4) occlusal contacts 5) interproximal contacts 6) pulpar or periodontal complication. To each of these parameters was given a degree of judgement expressed by Alpha, Bravo, Charlie, Delta. Alpha is the best evaluation, Bravo expresses a lower degree but clinically acceptable, Charlie and Delta are worse. Considering for each parameter the sum of the evaluations Alpha + Bravo, the clinically acceptable rate per cent of results has been quite good.

The authors report on 16 cases of recent traumatic diaphragmatic lesions in polytraumatized patients referred to them over the period 1979-86. After examining the diagnostic problems relating to this type of lesion, the authors describe the anatomico-topographical, clinical and therapeutic aspects. They conclude by stressing the need to explore the diaphragmatic cupulae systematically in the course of surgery for blunt abdominal trauma.
