Article Abstract
Objective: This study aimed to assess the oral impact on daily performance and its association with sociodemographic characteristics, tooth pain, need for prosthesis, and periodontal disease of adults in the state of São Paulo, Brazil.
Methods: This was a cross-sectional epidemiological study with secondary data obtained from the Oral Health Conditions Project- 2015 conducted in 163 municipalities in the state of São Paulo with the participation of 17,560 individuals. This study evaluated adults in the age-range between 35-44 years (n = 5,855), selected by means of probabilistic cluster sampling in two stages. The outcome variable was the OIDP (Oral Impacts on Daily Performances), obtained by using this instrument to assess daily activities (eating, speaking, oral hygiene, relaxation, sports practice, smile, study/work, social contact, and sleep). The independent variables were collected and grouped into three blocks: Block 1 (sex, age group, and ethnic group); Block 2 (household income and education); and Block 3 (tooth pain, need for prosthesis, bleeding, calculus, and periodontal pockets). A hierarchical multiple logistic regression analysis was performed considering the complex cluster sampling plan. Each observation was assigned a specific weight, depending on the location, which resulted in weighted frequencies adjusted for the effect of outlining.
Results: the female sex (p<0.0001), ethnic group black/mulatto (p<0.0001), low household income (p = 0.0112), up to 8 years of education (p<0.0001), tooth pain (p<0.0001), presence of bleeding (p<0.0001), and presence of periodontal pockets (p<0.0001) had greater oral impact on daily performance.
Conclusion: sociodemographic characteristics, tooth pain, and presence of periodontal disease were associated with oral impact on daily performance of the adult population in the state of São Paulo, Brazil.

Although the association of polyols/polyphosphates/fluoride has been demonstrated to promote remarkable effects on dental enamel, little is known on their combined effects on biofilms. This study assessed the effects of solutions containing fluoride/sodium trimetaphosphate (TMP)/xylitol/erythritol on dual-species biofilms of and . Biofilms were grown in the continuous presence of these actives alone or in different associations.
The skin serves a substantial number of physiological purposes and is exposed to numerous biological and chemical agents owing to its large surface area and accessibility. Yet, current skin models are limited in emulating the multifaceted functions of skin tissues due to a lack of effort on the optimization of biomaterials and techniques at different skin layers for building skin frameworks. Here, we use biomaterial-based approaches and bioengineered techniques to develop a 3D skin model with layers of endothelial cell networks, dermal fibroblasts, and multilayered keratinocytes.
Observations from the South Africa node of the Korea Microlensing Telescope Network (KMTNe-SAAO) were analyzed using the open source Photometry Pipeline (PP). PP can identify serendipitously observed asteroids in the observation fields which led to the extraction of 53 asteroid lightcurves. Rotational periods for 49 of these targets could be determined and are presented here.
