Article Synopsis
- The study systematically reviewed literature to evaluate how managing tooth wear affects the Oral Health Related Quality of Life (OHRQoL) in adults.
- Researchers followed established guidelines to select relevant studies and assess the quality of evidence, focusing on adult patients with moderate to severe tooth wear who received restorative treatments or counseling.
- Results showed that restorative treatment generally improves OHRQoL, while counseling had little to no impact; however, there were concerns about study biases, especially in non-randomized trials.
[Root canal post for build-up restorations: necessary or redundant?].
Ned Tijdschr Tandheelkd
February 2024
The purpose of root canal posts is to obtain additional retention for build-up restorations of endodontically treated teeth so they can be functionally reconstructed. Due to developments in adhesive dentistry and a lack of clinical evidence, root canal posts are used less and less. Currently, the advice of the European Society of Endodontology is to use a root canal post only in front teeth and premolars in the absence of remaining coronal dentine walls.

Methods: A prospective, randomized controlled trial, with equivalent parallel groups was designed. Eighty-two teeth were randomly allocated to the metal-ceramic or composite resin groups.
Article Synopsis
- The study investigates how the stiffness and presence of a composite core affect the fracture strength and failure modes of endodontically treated molars restored with ceramic or composite materials.
- Sixty depulped molars were tested using different restoration designs, including monolithic endocrowns and crowns with separate cores, to see how they hold up under simulated chewing conditions.
- Overall, no significant differences in fracture loads were found among the different restoration types, but the type of restoration and material did influence how they failed when subjected to stress.
Biomechanical properties of different endocrown designs on endodontically treated teeth.
J Mech Behav Biomed Mater
April 2023
Objective: To compare the biomechanical properties of different endocrown designs on endodontically treated teeth with an extensive defect in the mesial wall using a three-dimensional finite element method (3D FEM).
Methods: Four finite element analysis models were designed and built up based on different endocrown configurations in a mandibular molar. One model was designed as a butt joint preparation with 2 mm occlusal thickness(control), the other three models were butt joint designs with different distances between the bottom of the mesial wall preparation and the cemento-enamel junction (CEJ): 2 mm, 1 mm and 0 mm respectively.
