Abstract Scope Dentin-composite disks (ϕ5 mm × 2 mm) made from bovine incisor roots were subjected to diametral compression under: (1) fast fracture, (2) cyclic loading with a constant amplitude and (3) cyclic loading with a continuously increasingly amplitude. Prior to testing, the samples were stored in either deionised water or lactic acid solutions of pH 4.5 for 24, 48 and 120 hours at room temperature. The fracture data were then analyzed by using the Weibull probabilistic failure model. Low pH reduced both the Weibull modulus (from 8.2 to 5.6) and mean bond strength (from 16.6 to 12.2 MPa) of the dentin-composite disks under static and cyclic loading. The longer the challenge, the greater the reduction. The fatigue parameters produced by tests with an increasing load amplitude were similar to those produced by tests with a constant amplitude. This validated the accelerated fatigue test method.
