Objective: To investigate the association between periodontitis and self-reported halitosis among young adults, and whether there is an interaction between the effects of smoking and periodontitis on halitosis.
Methods: Data from the 1982 Pelotas birth cohort, Brazil, were used. The controlled direct effect of periodontitis on self-reported halitosis, not mediated by tongue coating, was estimated using marginal structural modeling.
Purpose: Assess the influence of anxiety symptoms on oral health related-quality of life in young women from a cohort study in Southern Brazil.
Methods: A sample of 535 young mothers were analyzed. Interviews and psychological evaluations were carried out by trained psychologists.
Aim: To systematically review the literature in order to investigate a potential association between periodontitis and halitosis.
Methods: Electronic searches were performed in four different databases: PubMed, Scopus, Web of Science and Scielo. Population-based observational studies that tested the association between periodontitis and halitosis were included.
Objective: This study aims to conduct a systematic review to determine the prevalence of halitosis in adolescents and adults.
Methods: Electronic searches were performed using four different databases without restrictions: PubMed, Scopus, Web of Science, and SciELO. Population-based observational studies that provided data about the prevalence of halitosis in adolescents and adults were included.
Purpose: This study investigated the effect of diamond bur grit size on the repair bond strength of fresh and aged resin composites.
Materials And Methods: Blocks of microhybrid composite (Opallis, FGM) were stored in distilled water at 37°C for 24 h (fresh composite) or subjected to 5000 thermal cycles (aged composite). The surfaces were roughened using diamond-coated, flame-shaped carbide burs with medium grit (#3168), fine grit (#3168F), or extra-fine grit (#3168FF).
Introduction: The capability of Halimione portulacoides, Spartina maritima, and Sarcocornia fruticosa (halophytes very commonly found in salt marshes from Mediterranean areas) for enhancing remediation of tributyltin (TBT) from estuarine sediments was investigated, using different experimental conditions.
Methods: The influence of H. portulacoides on degradation of the butyltin compounds was assessed in two different ways: (1) a 9-month ex situ study carried out in a site of Sado River estuary, center of Portugal, which used polluted sediments collected at other nonvegetated site from the same estuary; and (2) a 12-month laboratorial study, using both plant and sediment collected at a relatively clean site of Cávado River estuary, north of Portugal, the sediment being doped with TBT, DBT, and MBT at the beginning of the experiment.
