Effect of contemporary retraction agents and cleaning with hydrogen peroxide on the polymerization of elastomeric impression materials.

The aim of the study is to investigate the polymerization inhibition of elastomeric impression materials vinylpoly siloxane (VPS) and polyether (PE) when used in combination with retraction materials with and without subsequent cleaning with hydrogen peroxide (HO). Seven stainless steel specimens were fabricated. Four hundred and twenty impressions were made with three different elastomeric materials (140 each) as follows: group 1: VPS-Panasil; group 2: VPS-Express; group 3: PE-Monophase.

Assessment of framingham cardiovascular disease risk among militaries in the Kingdom of Saudi Arabia.

Objectives: To measure the risk factors for cardiovascular disease (CVD) among militaries in the Kingdom of Saudi Arabia and to assess their Framingham CVD risk.

Methods: A nationwide survey included 10,500 active military personnel selected by multistage stratified random sampling representing various ranks in the army forces of 5 regions. The study used the World Health Organization STEPwise approach to chronic disease risk factor surveillance (STEPS) in the design of data collection tool.
