Periodontal health is essential before and after a prosthetic restoration. Thus, the most accurate reproduction of the size and shape of dental crowns with that of natural teeth is the key to maintain a normal relationship between the joint and the occlusal relief and to maintain the integrity and health of periodontal tissues. Maintaining the periodontal health of the teeth with prosthetic restorations, with the placement of the margins in contact with the marginal gingival tissue, is a challenge, because the odonto-periodontal unit is constantly affected by microbial flora and the bacterial plaque accumulation can be stimulated by the presence of dental restorations. The objective of the present study was to analize the effects of fixed dental prostheses on periodontal inflammatory status and hygiene. After ethical approval, patients were clinically examined, their data was recorded and statistically processed. The results showed the existence of significant differences or correlations between the plaque, calculus or gingival indices and the characteristics of dental prosthesis in some situations. In conclusion, the presence of prosthetic restorations could influence the oral hygiene and be associated wih periodontal changes.
