Insights into the reinforcement role of peritubular dentine subjected to acid dissolution

4D microstructural changes in dentinal tubules during acid demineralisation

“…In summary, observations made with this technique, such as those made in the present study, could lead to the establishment of reliable numerical models of dentine demineralisation and the subsequent effects on the mechanical properties of dentine [35].…”

“…Furthermore, one of the drawbacks of the current experimental set-up was that the lactic acid solution was not directly agitated throughout the experiment. The result was that the released ions could have produced a so-called "Nernst diffusion layer" where the acid solution near the mineralised dentine surface became saturated and formed a protective layer, preventing further demineralisation [35]. Agitation of the acid solution would disrupt this layer and enable the demineralisation process to continue [36].…”

Finite Element Modelling and Experimental Validation of the Enamel Demineralisation Process at the Rod Level

“…FEM methods are nowadays employed in a number of numerical analyses and simulations to solve differential equations in complex shaped domains. Due to its great versatility, FEM fields of application span from structural to biological, from thermal to optical and so on [22] , [23] , [24] , [25] , [26] , [27] . Often, a multiphysics approach is sought by coupling and solving problems governed by different physics as well.…”

The Preliminary Investigation of the Effect of Caries on the Extension of Dentin Cracks

“…The effect of dental caries on the toughening mechanism of dentin was investigated from the perspective of stress distribution. After the occurrence of caries, the stress distribution gradually shifts from the PTD to the ITD, which leads to a significant increase in the risk of ITD destruction (Hu, 2020).…”
