The Brazilian validation of a health literacy instrument: the newest vital sign.

Objective: This study aimed to perform the cross-cultural adaptation and validation of the NVS for Brazilian Portuguese.

Material And Methods: Two hundred and fifty adults responded to the adapted version of the NVS, the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30), ten questions of the National Functional Literacy Index (NFLI), and a questionnaire about demographic and oral health-related aspects. Statistical analysis determined the internal consistency, stability, difficulty of items, and convergent/discriminant/predictive validities of the NVS.

Determining acceptable limits for water sorption and solubility of interim denture resilient liners.

Statement Of Problem: Specifications for determining acceptable limits of water sorption (WS) and solubility for interim denture resilient liners are lacking.

Purpose: The purpose of this in vitro study was to evaluate the WS and solubility of interim resilient materials throughout their lifespans.

Material And Methods: Specimens (n=10) of 7 tissue conditioners, Coe-Comfort (CC), Softone (ST), Rite-Line (RL), Dura Conditioner (DC), Hydrocast (HC), Dentusoft (DS), and Visco-gel (VG) and 2 interim resilient liners, Trusoft (TS) and Coe-Soft (CS), were submitted to desorption until weight stabilization.
