Abstract

Objective: To evaluate the effectiveness of types of dental materials (all-porcelain andporcelain -fused to metal crowns) using to make crownsinfluence on the  gingival tissuesaround crowns. Material and methods: 20 patients with the upper maxillary molars had been root canal treatment at the Clinical Department  3, Faculty of Odonto Stomatology, University of Medicine and Pharmacy, Ho Chi Minh City, recruited in the study. The subjects were divided into 2 groups, included 10 -subject group was treated with all-porcelain crowns and 10 -remain group treated with porcelain-fused to metal crowns. Periodontal parameters were recorded immediately after crown cementations, 45 and 90 days subsequently. Results: The periodontal clinical parameters at the time of crown cementations, 45 and 90 days after fixed crowns showed no statistically significant differences between two groups using all-porcelain crown and porcelain – fused to metal crowns. Crown prostheses caused to lightly increasing the plaque index and gingival index in both groups but there were no statistically significant differences (p > 0.05). Conclusion: There were  no significant  differences in the effects of using all-porcelain or porcelain -fused to metal crowns which influence  on the gingival tissue  parameters .
