Comparative Study
Comparative tensile strengths of preceramic and postceramic solder connectors using high-palladium alloy.
It is not known whether different high-palladium alloys of similar composition possess comparable tensile strength properties associated with connector soldering. ⋯ Rx Naturelle Plus solder connectors provided better strength with the preceramic as opposed with the postceramic connectors. For postsolder connectors, Rx Naturelle Plus alloy had less acceptable strength and a wider variation, suggesting it is more technique sensitive than Option alloy connectors.

There is no consensus on the association between occlusion and temporomandibular disorders (TMD). ⋯ Occlusal features showed a low predictive value to detect muscle disorders of the stomatognathic system. Multifactorial complex pathologies, such as TMD, should be studied using multivariate statistical analyses, as univariate models may overestimate some resulting associations.

Comparative Study
The association between wear facets, bruxism, and severity of facial pain in patients with temporomandibular disorders.
It is unclear whether patients with temporomandibular disorders (TMD) who report high levels of bruxism have more severe signs and symptoms of TMD and more advanced tooth wear than patients with TMD who report lower levels of bruxism. ⋯ In this TMD population, tooth wear factors did not differentiate patients with bruxism from those without. The amount of bruxism activity was not associated with more severe muscle pain and was associated with less pain in the TMJ on palpation.
