    Efecto del espesor y material Cad/Cam en la resistencia a la fatiga de molares tratados endodónticamente restaurados con carillas oclusales

    Endodontically treated teeth lose a certain amount of healthy dental tissue to make the preparations, which must comply with the thicknesses indicated by the manufacturer to guarantee their resistance. General Objective: To evaluate the influence of the thickness and type of material on fracture resistance in endodontically treated teeth (ETT) restored with occlusal veneers (OV). Materials and methods: 60 dental organs extracted by orthodontics or periodontics were included and divided into control group, Cerasmart 0.5-0.6mm group, Cerasmart 1.5-1.6mm group, Celtraduo 0.5-0.6mm group and Celtraduo 1.5-1.6mm group. The experimental groups were prepared according to the aforementioned thicknesses. A Kruskal-Wallis test was performed, for post hoc data the T3 Dunnett test was performed. Results: The experimental group that presented the highest value was G. CeltraDuo 1.5- 1.6mm with 618.21 newton, followed by Cerasmart 1.5-1.6mm with 579.14 newton. Between the control and CeltraDuo 0.5-0.6mm groups there was a significant difference p=0.025. Conclusion: Evaluation of restoration thickness revealed that increased restoration thickness does not influence the fracture resistance of endodontically treated premolars.
