How would a dental office decide which dental materials to use? 1. Use samples. 2. Analyze publications. 3. Dentists preference. 4. Patient treatment needs. a. 1, 2, 3, 4 b. 1, 2, 3 c. 1, 2 d. 1 ANS: A The American Dental Association advocates the use of evidence-based dentistry to choose which dental materials are best utilized in the assessment of which dental materials best represent the needs of the dental practice. This evidence is based on scientific information published in professional publications. Other considerations including the use of samples provided by manufactures representatives, the dentists preference related to properties and handling, as well a materials selected for a patients individual treatment needs.

Which of the following restorative techniques was first introduced in 1955? a. Cast gold inlays b. Cohesive gold foil c. Acid-etch technique d. Synthetic resins for denture bases ANS: C The acid-etch technique was introduced in 1955. Cohesive gold foil, which could be condensed directly into the cavity preparation, was introduced in 1855. In 1907, Dr. William Taggart demonstrated a casting method to produce gold inlays. Synthetic resins were introduced in 1932; these resins soon replaced rubber as the denture base of choice. Around this time, synthetic resins also became a popular tooth-colored alternative, and, together with the introduction of the acid-etch technique, they have evolved into composite resin, one of the most popular restorative materials.

What is Dr. Frederick McKay credited with? a. Developing an acceptable formula for silver dental amalgam. b. Demonstrating a casting method to produce gold inlays. c. Noting dental fluorosis in Colorado Spring. d. The introduction of dental cements. ANS: C Dr. Frederick McKay is credited with noting dental fluorosis in Colorado Springs in 1901. Together with G.V. Black, he determined that drinking water was the factor. These caries-free but mottled teeth prompted Dr. McKay to suggest changes in the water supply, leading to the first community water fluoridation programs in 1945.

Since 2005, the American Dental Association (ADA) Seal of Acceptance is awarded to _____ products. a. both professional and consumer b. professional but not consumer c. consumer but not professional d. neither professional nor consumer ANS: C Since 2005, the American Dental Association (ADA) Seal of Acceptance is awarded to consumer but not professional products. Although strictly a voluntary program, more than 1300 consumer dental products carry the Seal of Acceptance. Most common among these are toothpaste, toothbrushes, mouth rinses, floss and other interdental cleaners, sugar-free chewing gum, and denture adherents and cleansers.

Food and Drug Administration b. Drug Enforcement Administration c. Centers for Disease Control and Prevention d. Department of Human and Health Services ANS: B Dental materials considered devices, as well as over-the-counter products sold to the public, are subject to control and regulation of the Food and Drug Administration Center for Devices and Radiological Health. The original Food and Drug Act of 1906 did not include provisions to ensure medical and dental device safety or claims. In 1976, the Medical Device Amendment was signed to give the Food and Drug Administration regulatory authority over medical and dental devices, which are now classified and regulated according to their degree of risk to the public.

It helps consumers make informed decisions about the safety and efficiency of products. c. The ADA Seal is usually awarded for the life of the product. d. Once a product has been accepted, it does not need to be reevaluated if its composition changes. ANS: B Consumers and dentists rely on the ADA Seal to assist them in making informed decisions regarding a product’s safety and efficiency. Not all dental products qualify for the Seal. The ADA Seal is usually awarded for a period of 5 years, at which time the product is reevaluated. Products that have been previously accepted are also reevaluated anytime their composition changes.
