[A survey on biomarkers and early diagnosis in Alzheimer's disease].

Given the potential use of biomarkers in the diagnosis of Alzheimer's disease (AD) in early stages, new ethical and communication dilemmas appear in everyday clinical practice. The aim of this study was to know the opinion of health professionals (HP) and general public (GP) on the implementation of early diagnostic techniques in AD and the use of biomarkers for this purpose. A survey with multiple choice answers was elaborated in two versions: one for HP and the other for GP.

Effect of saliva contamination on bond strength with a hydrophilic composite resin.

Objective: To evaluate the influence of saliva contamination on the bond strength of metallic brackets bonded to enamel with hydrophilic resin composite.

Methods: Eighty premolars were randomly divided into 4 groups (n = 20) according to bonding material and contamination: G1) bonded with Transbond XT with no saliva contamination, G2) bonded with Transbond XT with saliva contamination, G3) bonded with Transbond Plus Color Change with no saliva contamination and G4) bonded with Transbond Plus Color Change with saliva contamination. The results were statistically analyzed (ANOVA/Tukey).

Blood contamination effect on shear bond strength of an orthodontic hydrophilic resin.

Objective: The aim of this study was to assess the impact of blood contamination on shear bond strength (SBS) and bond failure pattern of metallic brackets bonded using a new hydrophilic resin.

Material And Methods: Eighty human premolars were randomly allocated into 4 groups (n=20) according to the bonding material and contamination pattern. GI: brackets bonded with the Transbond XT conventional system without contamination; GII: brackets bonded with the Transbond XT conventional system with blood contamination; GIII: brackets bonded with the Transbond Self Etching Primer and Transbond Plus Color without contamination; GIV: brackets bonded with the Transbond Self Etching Primer and Transbond Plus Color with blood contamination.

Mild behavioral impairment and risk of dementia: a prospective cohort study of 358 patients.

Background: Mild cognitive impairment (MCI) is a transitional state between normal aging and dementia, at least for some patients. Behavioral symptoms in MCI are associated with a higher risk of dementia, but their association with dementia risk in patients without MCI is unknown. Mild behavioral impairment (MBI) refers to a late-life syndrome with prominent psychiatric and related behavioral symptoms in the absence of prominent cognitive symptoms that may also be a dementia prodrome.

Root formation of an autotransplanted tooth.

Traumatic injuries with loss of anterior teeth occur more frequently in children. Treatment of the dental trauma is complex and requires a comprehensive and accurate diagnostic and treatment plan. It is also important to consider the biological, functional, esthetic, and economic aspects.
