Abstract
The authors have performed a clinical study - 175 crown obturations of class II, II, V and cavities have been analyzed in 125 patients, following their impact on the marginal periodontium and a radiological study - consisting of the analysis of 108 proximal amalgam obturations and of their negative effects on the profound periodontium. The results showed alarming percentages (over 80% in the clinical examination and 87% in the radiological examination of improper restorations, which generated periodontal alterations, from gingivitis to chronic marginal progressive periodontitis. The percentage of 59.26% obturations that triggered different degrees of osseous lysis imposed the need of knowing the negative effects of direct restorations on the periodontium and also the importance of applying the specific preventive measures.
