1. Resistance to compression of weakened roots subjected to different root reconstruction protocols

OBJECTIVE: This study evaluated, in vitro, the fracture resistance of human non-vital teeth restored with different reconstruction protocols. MATERIAL AND METHODS: Forty human anterior roots of similar shape and dimensions were assigned to four groups (n=10), according to the root reconstruction protocol: Group I (control): non-weakened roots with glass fibe

2. Resistência à fratura de raízes fragilizadas restauradas com resina composta e pinos de fibra de vidro submetidas à ciclagem mecânica / Resistance to fracture of weakened roots restored with composite resin and glass fiber post submitted to cyclic loading

The preservation and restoration of severely weakened pulpless teeth is a difficult and unpredictable procedure. This study evaluated the resistance to fracture and fracture patterns of weakened roots after restoration with glass fiber post, filling core of composite resin and total metallic crown submitted to cyclical and compressive load. Thirty upper cani

3. Reforço intra-radicular de raizes debilitadas

The aim of this study was to evaluate the fracture resistance of seventy inferior bovine incisors, weakened and restored with different intra-root retention systems: cast post and core; cast post and core with composite resin reinforcement; Flexi-Post; Flexi-Post with polyethylene fiber - Ribbond; Luscent Anchors post; and intra-root retention with Ribbond.
