Abstract
The objective of the present study was to determine the effect periodontal disease on the bond strength of fiberglass posts, different adhesive systems and resin cements. Ninety human maxillary central incisors roots extracted due to periodontal disease or prosthetic reasons were endodontically treated and divided into six experimental groups: NPD-ARC – no periodontal disease/RelyX ARC and Adper Single Bond 2; NPD-PF – no periodontal disease/Panavia F and ED Primer; NPD-U – no periodontal disease/RelyX U100; PD-ARC – periodontal disease/RelyX ARC and Adper Single Bond 2; PD-PF – periodontal disease/Panavia F and ED Primer; and PD-U – periodontal disease/RelyX U100. Specimens were subjected to push-out test and data were analyzed by two-way ANOVA and Tukey’s test (p = 0.05). The periodontal disease groups showed that the Panavia F/ED Primer group presented no significantly higher mean values compared with RelyX U100, and that both presented significantly higher mean values when compared with RelyX ARC/Single Bond 2 group. These results were also observed in roots with no periodontal disease. There were no differences in bond strength mean values of roots related or not to periodontal disease.

Summary
A persistent problem in clinical dentistry is associated with fractures occurring in endodontically treated teeth [1]. Restoration of these teeth, in some cases, can be a complicated process because of extensive structural defects resulting from caries, cavity access and the excessive removal of radicular dentin during endodontic treatment [2,3,4]. Numerous restoration techniques for endodontically treated teeth have been advocated with criteria for success dependent upon variations in length, diameter, shape and surface configuration, quantity of dentinal structure, and materials and techniques used in reconstruction [6,7,8]. The post functions primarily to aid the retention of the restoration and to protect the tooth by dissipating or distributing forces along the tooth [11]
