“…Some studies showed that wear tests conducted under acidic conditions lead to a higher enamel wear than tests carried out in neutral solutions [ 39 ]. Contrarily, others found lower enamel wear when tested in the presence of acidic media [ 40 , 41 , 42 , 43 , 44 ]. In fact, Wu et al [ 41 ] found that the influence of acids on enamel wear depends on reduction of hardness that these induce on the enamel surface.…”

This review focuses on the wear mechanisms of natural and restorative dental materials, presenting a comprehensive description and analysis of the works published in the last two decades on the wear at the interface of occlusal surfaces. Different groups of tribological pairs were considered: tooth-tooth, tooth-restorative material (tooth-ceramic, tooth-resin-based-materials, and tooth-metal), and restorative-restorative materials. The lack of standardization of the wear tests impairs the direct comparison of the obtained results. However, it was possible to infer about the main wear mechanisms observed on the different classes of dental materials. Concerning ceramics, their toughness and surface finishing determines the wear of antagonist tooth. Abrasion revealed to be the main wear mechanisms at occlusal interface. In the case of resin-based composites, the cohesion of the organic matrix and the nature, shape, and amount of filler particles greatly influences the dental wear. The protruding and detachment of the filler particles are the main causes of abrasion of antagonist enamel. Metallic materials induce lower wear on antagonist enamel than the other classes of materials, because of their low hardness and high ductility. Most of the studies revealed plastic deformation and adhesive wear as the main wear mechanisms. Overall, more research in this area is needed for a better understanding of the mechanisms involved at the occlusal surfaces wear. This would be essential for the development of more suitable restoration materials.

“…37 When tooth wear progresses, it exposes the underlying soft dentin, which is more susceptible to the deleterious effects of wear. 38 Wear patterns do not appear to reflect the etiology suggested and many diagnostic indices do not properly reflect the morphological defects. Besides, there is little international standardization for such indices.…”

“…As acknowledged in the literature, wear of teeth in the oral environment is generally due to different wear processes and/or their interplay with one dominating the other. 38 Acid environment was found to accelerate the wear rate; pH was then monitored. Mean pH values were in agreement with Aframian et al, 33 and showed that volunteers nearly maintained mean pH values in the tested period of 45 days.…”

Two-dimensional profilometry is an inexpensive well-established technique to identify indicators of tooth wear. Four surface parameters ( Ra, Rq, Rsk, and Rku) were selected in this work to evaluate worn dental surfaces using two-dimensional profilometry. Eight subjects with dental wear were molded four times with a 15 days interval. To verify data correlation, a mixed-effects model was adjusted. The results indicated that Ra, Rq, Rsk are time dependent, while Rku remained constant. Rsk and Rku values were useful to identify surfaces. Skewness had oscillatory variations and Rku was tending toward a constant rate for a longer period. Two regimens were suggested: (1) transient and (2) self-limiting. Final variation rates indicated that, although enamel wear transiently modifies the surface, it maintains its isotropic characteristic: symmetrical and approximately normal asperities distribution.

Las lesiones dentales no cariosas comprenden un conjunto de procesos que se caracterizan por la pérdida o el desgaste pa- tológico de los tejidos duros del diente, como ser el esmalte y la dentina. En la etapa inicial es difícil el diagnóstico, cuando la lesión va en aumento y si no es tratada a tiempo ni se modifican los factores de riesgo pueden llegar afectar de manera progresiva la pulpa dental. Estas lesiones han aumentado en los últimos años, debido al mayor tiempo de dien- tes en boca, acompañado de hábitos parafuncionales y dietas altamente acidas, a esto se le agrega el estrés que también provoca perdida de estructura dental. Por lo que no toda perdida de tejido mineralizado de los diente es provo- cada por una carga bacteriana. Estas lesiones no cariosas difieren en su etiología, se debe ser muy minucioso en su evaluación clínica y descripción, ya que muchas características clínicas pueden generar un diagnóstico erróneo y por ende un tratamiento no predecible, se debe tomar en consideración la existencia de combinaciones entre lesiones. Objetivo: Conocer la etiología y características clínicas propias de cada lesión, para poder realizar un diagnóstico oportuno y seguro. La revisión se realizó por medio de una búsqueda en internet en los buscadores de Hinari, Science Direct, Google académico, revisando artículos originales y revisiones bibliográficas entre los años de 2014- 2019. Conclusiones: Las lesiones dentales no cario- sas tienen etiologías multifactoriales, características clínicas diferenciales y puede haber una combinación de varias patologías.
