Chapter 8 - Oral Pathology Flashcards
What is the science that reads the nature, causes, and development of oral diseases?
Oral pathology
Salivary glands secrete about how many ml of saliva on a daily basis
1,500 ml
Microscopic counts in saliva show an average of how many microorganisms per milliliter?
750 million
What can be defined as any pathological or traumatic disorder of tissue that creates a loss of function of the area affected?
Oral lesions
What is a localized collection of pus in a specific area of soft tissue or bone that is commonly caused by a bacterial infection?
Abscess
What is a enclosed pouch or sac containing fluid or semi-solid material?
Cyst
What are a disruption of the superficial covering of the mucosa or skin caused by biting, denture irritation, toothbrush injury, viruses or other irritants?
Ulcers
What disease is caused by a microbial process that starts on the surface of the teeth and leads to the breaking down of the enamel, dentin, and cementum. The surface is noted as roughened when dental explorer point is passed?
Dental Caries
The process that destroys the hard surfaces of the tooth is called what?
Decay
The cause of tooth decay has been linked to a group of bacteria called what, and other acid producing bacteria that are in the oral cavity?
Streptococci
If the tooth surface has an area that has not progressed past the decalcification stage, this type of carious lesion is called what?
Incipient
What are decay processes that occur underneath existing dental restorations?
Recurrent Caries
What refers to pain in the dental pulp and commonly occurs after s restoration has been placed in a tooth. May become sensitive to touch, temperature changes, sweet or sour foods. Pain may increase when lying or walking upstairs?
Pulpalgia
What is an inflammation of the dental pulp, caused by a bacterial infection resulting from dental caries or fractured teeth. Build up of pressure in the canal?
Pulpitis
What results when the pulp has become inflamed and a small pus-like abscess forms in the pulpal canal. Patient may feel tooth is “high” when biting. May appear like a “grape” in X-Rays?
Periapical Abscess
The death of tissue is called what? It occurs as a result of untreated pulpitis from a traumatic injury.
Necrosis
What is the most prevalent chronic disease of humankind?
Periodontal disease
What is an inflammation involving the gingival tissues?
Gingivitis
What is the most common type of gingival disease that is the result of poor oral hygiene?
Marginal Gingivitis
What is an inflammation of the gingiva around a partially erupted tooth? the mandibular third molars are most often affected and has a “gingival flap”.
Pericoronitis
The most common of all the herpetic HSV-1 lesions is what?
Herpes labialis
The recurrent HSV-1 lesions take about how many days to resolve?
7 to 10
What is the main cause of acquired immunodeficiency syndrome (AIDS)?
Human Immunodeficiency Virus (HIV)
What is the loss of substance of a tooth from a wearing away process caused by teeth against teeth, for example mastication of food?
Attrition
What results in the loss of tooth structure secondary to the action of external agents (biting foreign objects such as pipe stem, thread, bobby pins)?
Abrasion
What is the loss of tooth substances from a chemical process that does not involve bacteria? Usually occurs on the facial surfaces at the gingival third of the crown and often involves the maxillary incisors.
Erosion
Some ties of lesions are called what because the factors producing this condition are unknown or may occur from a known acid source such as people who have bulimia, an eating disorder characterized by binge eating and self induced vomiting?
Idiopathic erosion
What is referred to as Vincent’s infection, but it is commonly known as trenchmouth? It has the characteristics of white or grayish tissue around the teeth, unpleasant odor and a foul taste in the mouth, and a “punched-out” appearance.
Necrotizing Ulcerative Disease (NUG)
