Introduction : Nanohybrid composite resin is a restorative material that often used because of its aesthetics and adequate mechanical properties. One the properties nanohybrid resins diametral tensile strength, which affects strength when receiving chewing loads in oral cavity. The value can be influenced by several factors, namely food, drink, saliva. Human saliva has different pH levels alway...

O comportamento do biomaterial Co-Cr-Mo (usado em próteses dentárias) em saliva artificial (AFNOR S90-701), saliva artificial com temperatura e pH modificados e contendo fluoreto foi estudado por técnicas eletroquímicas (potencial de circuito aberto e polarização potenciodinâmica) e de análise de superfície (Microscopia Eletrônica de Varredura (MEV) e Espectroscopia de Energia Dispersiva (EED))...

BACKGROUND Human immunodeficiency virus (HIV) causes severe immunosuppression due to progressive decrease in the CD4 T lymphocyte cells during the course of the disease and this affects all the body systems including glandular secretions. A number of lesions affecting the salivary glands have been noted in HIV infection. The objective of this study was to evaluate the salivary pH and the buffer...

Cylindrical specimen (20 mm x 5 mm, n = 5) consisting of commercially pure titanium ASTM/grade 2 (Ti2 – Dentaurum J.P. Winkelstroeter KGPforzheim, Germany) were casted in the Rematitan system (Rematitan, Dentaurum J.P. Winkerstroeter KG, Pforzheim, Germany) by Vaiazzi Dental Laboratory (São Paulo SP, Brazil). All specimens were cold mounted with epoxy resin and then received the standard metall...

Preparations containing organic and inorganic fluorine compounds are used for oral hygiene. Fluoride ions contained in these preparations display high bioactivity and can alter the environment of the mouth. The aim of the study was to determine the effect of preparations containing aminofluorides, commonly used in oral hygiene, on the activity of salivary cathepsin C (EC 3.4.14.1). The research...

OBJECTIVES To evaluate the salivary flow rate (SFR),  pH, and buffer capacity (BC) among healthy shammah users (SU) in comparison with healthy non-shammah users (NSU). Methods: This case-control study was conducted at the College of Dentistry, Jazan University, Jazan, Kingdom of Saudi Arabia between March 2016 and May 2017. A sample of 27 SU and 30 NSU were recruited. Unstimulated saliva was co...
