Dental ‘Erosion’ Revisited

The influence of occlusal loads on stress distribution of cervical composite resin restorations: A three-dimensional finite element study

“…The stress pattern in the same area is changed continuously from compressive to tensile, especially underneath the enamel, since dentin appears to be substantially stronger than enamel when under lateral forces. Thus, the cyclic occurrence of compression and tension may reach the fatigue limit and lead to rupture of the chemical bonds between the hydroxyapatite crystals 5,27,28) . Posterior teeth were more likely to exhibit NCCLs, possibly owing to the fact that greater occlusal forces and more lateral forces are exerted in the posterior teeth.…”

Prevention. Part 3: Prevention of tooth wear

“…The patient may also show other signs of more severe bruxism. A particular diagnostic problem is the condition sometimes termed abfraction where cervical erosions occur in several teeth thought by some authors 19,20 (Type 4) to be caused by lateral occlusal forces acting in an acidic environment. These conditions may be found in a patient with bruxism who also has gastric reflux or who consumes acidic foods or beverages frequently.…”

Análise quantitativa e qualitativa da condutividade hidráulica da dentina após tratamento com diferentes agentes dessensibilizantes. Estudo in vitro

“…Sua ocorrência tem sido cada vez mais frequente na população, afinal essa região, devido à menor espessura do esmalte, torna-se a mais vulnerável ao desgaste com a maior permanência dos dentes na boca (PEGORARO et al, 2005;GRIPO;SIMRING, 1995). Assim, a exposição da dentina cervical é mais frequente na face vestibular dos dentes, principalmente nos caninos e premolares, e sua prevalência aumenta com a idade e em pacientes com boa higiene bucal (ADDY; WEST, 1994;TAR et al, 2002).…”
