Experimental composites containing quaternary ammonium methacrylates reduce demineralization at enamel-restoration margins after cariogenic challenge.

Objective: This study evaluated the influence of experimental composites containing quaternary ammonium monomers (QAM) at different concentrations and alkyl chains on demineralization at enamel-composite margins after cariogenic challenge.

Methods: Standardized 4×4mm cavities were cut into 35 bovine enamel blocks, which were randomly divided into seven groups (n=5) and restored with the following experimental composites and commercial materials: (G12.5) - 5% dimethylaminododecyl methacrylate (DMADDM) with a 12-carbon alkyl chain (G12.

Does flavoured dentifrice increase fluoride intake compared with regular toothpaste in children? A systematic review and meta-analysis.

Background: Toothpaste manufacturers encourage through aggressive marketing strategies the overconsumption of fluoridated dentifrices. There are conflicting results regarding fluoride intake from toothpastes in children.

Aim: The aim of this systematic review and meta-analysis was to determine whether dentifrice flavour increases fluoride ingestion by children.

Homeopathic therapy for sleep bruxism in a child: Findings of a 2-year case report.

Living better or living longer? Perceptions of patients and health care professionals in oncology.

Background: Cancer can influence the views of patients on treatment goals and make them different from those of health care professionals (HCPs). It is crucial to understand patient expectations regarding cancer treatment.

Methods: We performed a cross-sectional survey of patients with cancer and HCPs to evaluate their perceptions about treatment priorities and to analyse variables that might influence their opinions.

Treatment priorities in oncology: do we want to live longer or better?

Objectives: Despite the progress achieved in the fight against cancer over the past several years, assessing the needs, goals and preferences of patients with cancer is of the utmost importance for the delivery of health care. We sought to assess priorities regarding quantity versus quality of life among Brazilian patients, comparing them with individuals without cancer.

Methods: Using a questionnaire presenting four hypothetical cancer cases, we interviewed cancer patients, oncology health-care professionals and laypersons, most of whom had administrative functions in our hospital.
