Dental instruments are the tools that dental professionals use to provide dental treatment. They include tools to examine, manipulate, restore and remove teeth and surrounding oral structures.
Standard instruments are the instruments used to examine, restore and extract teeth and manipulate tissues.
Dental braces (also known as orthodontic braces, or braces) are devices used in orthodontics that align and straighten teeth and help to position them with regard to a person's bite, while also working to improve dental health. They are often used to correct underbites, as well as malocclusions, overbites, cross bites, open bites, deep bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws.
To assume a brace or crash position is an instruction that can be given to prepare for a crash, such as on an aircraft; the instruction to brace for impact is often given if the aircraft must make an emergency landing over land or water.
Wal-Mart has been subject to criticism by numerous groups and individuals. Among these are labor unions, community groups, grassroots organizations, religious organizations, environmental groups and Wal-Mart customers. They have protested against Walmart, the company's policies and business practices, including charges of racial and gender discrimination. Other areas of criticism include the corporation's foreign product sourcing, treatment of product suppliers, environmental practices"." USA Today., the use of public subsidies, and the company's security policies. Wal-Mart denies any wrongdoing and maintains that low prices are the result of efficiency.
In 2005, labor unions created new organizations and websites to influence public opinion against Wal-Mart, including Wake Up Wal-Mart (United Food and Commercial Workers) and Walmart Watch (Service Employees International Union). By the end of 2005, Wal-Mart had launched Working Families for Wal-Mart to counter criticisms made by these groups. Additional efforts to counter criticism include launching a public relations campaign in 2005 through its public relations website, which included several television commercials. The company retained the public relations firm Edelman to interact with the press and respond to negative media reports, and has started interacting directly with bloggers by sending them news, suggesting topics for postings, and sometimes inviting them to visit Walmart's corporate headquarters. In November 2005, a documentary film critical of Wal-Mart (Wal-Mart: The High Cost of Low Price) was released on DVD.
