Week 3 Flashcards
Disease in which there is severe chest pain because the heart muscle is deprived of oxygen. Painful but does not lead to death or permanent heart damage.
Angina
Federal agency charged with establishing guidelines and regulations regarding worker safety.
OSHA ( occasional safety and health administration)
Fainting
Syncope
Interruption of blood flow to the brain lasting long enough to cause damage to the brain and resulting in loss of brain function. Cerebrovascular accident (cva)
Stroke
Blood borne viral disease. Attacks and weakens or destroys the immune system.
HIV (human immunodeficiency virus)
Also known as lockjaw. Often fatal caused by spore forming bacillus found in soil dust or animal feces. Usually introduced into the body though a wound or break in the skin.
Tetanus
Forms that provide health and safety information regarding materials that contain chemicals.
Msds medical safety data sheet
The hard glistening tissue covering the anatomic crown of the tooth. The outermost layer of the coronal portion of the tooth that overlays and protects the dentin.
Enamel
An allergic reaction characterized by sudden collapse, shock, or respiratory and circulatory failure from the presence of an allergen.
Anaphylaxis
An infectious disease caused by mycobacterium tuberculosis and characterized by the formation of tubercles in the tissue. It is the leading cause of death worldwide from infectious disease.
Tb tuberculosis
A form assumed by some bacteria that is resistant to heat, drying, and chemicals. They represent the most resistant form of known life.
Spores
Tapered end of each root tip
Apex
A rotary cutting instrument of steel or tungsten carbide, supplied with cutting heads of various shapes.
Bur
Virus that causes serious disease that may result in prolonged illness, liver cancer, cirrhosis of the liver, liver failure and even death. It is a blood borne disease that is transmitted by other bodily fluids including saliva.
Hepatitis b
A shaft on which a working tool is mounted, as in a dental drill.
Mandrel
Food poisoning. Spread from person to person by putting something in your mouth that has been contaminated with the stool of someone with virus. A vaccine is available.
Hepatitis A
No vaccine. Transmitted through blood exposure. Needle sticks. Percutaneous (through skin) this disease progresses to chronic hepatitis in up to 50% of patients acutely affected.
Hepatitis C
Causes reoccurring sores on lips. Fever blisters or cold sores. Healing begins in 3 days and illness is usually over in 7 to 14 days. After infection in childhood the virus lies dormant and reappears later in life as familiar reoccurring fever blisters or cold sores.
Herpes simplex type 1
Also known as genital herpes. One of the most common sexually transmitted disease in the United States.
Herpes virus type 2
Carried in the blood and body fluids of infected individuals and can be transmitted to others
Blood borne transmission
Area around the apex
Periapical
Designed to protect employees against occupational exposure to blood-borne disease causing organisms such as hepatitis B virus hepatitis C virus and human immunodeficiency virus. Requires employers to protect their employees from exposure to blood and other potentially infectious materials in the workplace and provide proper care to an employee should an exposure occur.
Blood-borne pathogen standard (BBP)
Requires employers to inform their employees about the identity and hazardous chemicals that they use in the workplace. Also known as employee right to know law.
Hazard communication standard
Used to carry amalgam to the prepared tooth (filling)
Restorative instrument.
Amalgam carrier
Often referred to as straight hand piece because of it’s straight-line design. 25,000 revolutions per minute (rpm) don’t want to hit nerve going through dentin so doctor uses this. Contra angle attachment and straight attachments.
Low-speed hand piece
Speeds of 450,000 RPM. The bulk of the tooth structure is removed using this device. Equipped with Waterspray device to cool tooth and remove debris. May have fiber optic light
High-speed handpiece
Removes soft dentin, debris and decay from a tooth. A versatile instrument. Tooth preparation instrument.
Excavator
Holds newly mixed amalgam. Is placed and retrieved. Accessory instrument.
Amalgam well
Types of hand instruments
1 examination instruments
2 tooth preparation instruments
3 restorative instruments
4 accessory instruments
Smoothes and burnishes the amalgam before the material hardens. Restorative instrument.
Burnisher
amalgam, bonded,
a composite of tooth-colored acrylic resin and finely ground glass-like particles that is bonded or adhered to the tooth during dental restoration. The advantage is that less of the tooth structure needs to be removed during the restoration, resulting in a smaller filling compared with traditional amalgams.
2. a composite filling.
Condenser
commonly used in dentistry, as vessels for mixing dental medicaments or fillings
Dappen fish
Fainting
Syncope
Heart attack
Myocardial infraction
Too much oxygen
Hyperventilation
Unconsciousness that can occur when patient assumes upright position too quickly.
Postural hypotension
Contain health and safety information about every chemical in the office
Material safety data sheets MSDS
Contaminated needles, scalpel blades, orthodontic wires endodontic instruments go here. Close-able leak proof container
Sharps
