The aim of this general article is to present an overview of the current knowledge about composition and structural changes and also about specific biomechanical alterations related to vitality loss or endodontic therapy. For a long time, these issues have been controversially approached from a clinical standpoint and are therefore still confusing for many practitioners. Vitality loss or endodontic procedures seem to induce only negligible changes in hard dental tissue moisture. Physico-chemical properties of dentin can be modified by some of the endodontic chemical products used for chemo-mechanical debridement. On the other hand, tooth biomechanical behavior is affected, since tooth strength is reduced proportionally to coronal tissue loss, due to either pre-existent carious/non-carious lesions or cavity acces preparation, besides restorative procedures. The related literature shows the lack of accepted clinical standards and consensus regarding the optimal way of approaching the specific tooth biomechanics following endodontic therapy.read more

TL;DR: The induction of DNA double-strand breaks (DSBs) by ChKM and monochlorophenol compounds was tested in human gingival fibroblasts and an additive DNA toxicity was found for 4-CP in combination with camphor in the ChKm solution, compared to the 4- CP alone.

Peri-Cervical Dentin (PCD) : A New Paradigm for Endodontic Success
TL;DR: The treatment planning should integrate principles of Conservative Endodontic Cavity, minimally invasive endodontics,biomimetic endodentic shaping and biomimetic reinforcement and restoration to ensure that sufficient PCD is preserved and further reinforced as well.

Reduction in tooth stiffness as a result of endodontic and restorative procedures.
TL;DR: Results on 42 teeth indicate that endodontic procedures have only a small effect on the tooth, reducing the relative stiffness by 5%.

The Mechanical Properties of Human Dentin: a Critical Review and Re-evaluation of the Dental Literature:
TL;DR: A critical re-evaluation of the literature indicates that the magnitudes of the elastic constants of dentin must be revised considerably upward, and the large coefficients of variation cited in all strength studies can be understood in terms of a distribution of flaws within the dentin specimens.

Ferrule design and fracture resistance of endodontically treated teeth.
TL;DR: One millimeter of coronal tooth structure above the crown margin substantially increased the fracture resistance of endodontically treated teeth, whereas a contrabevel at either the tooth-core junction or the crownmargin was ineffective.
