[Total amalgam reconstruction. Clinical evaluation after three years]

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.
