allergy an unwanted bodily response to a substance or organism
allergic reaction The hypersensitive response of the immune system of an allergic individual to a substance

When an allergen enters the body, it causes the body's immune system to develop an allergic reaction in a person with an allergy to it. This reaction can occur when the immune system attacks a normally harmless substance (the allergen). The immune system calls upon a protective antibody called immunoglobulin E or IgE to fight these invading substances. Even though everyone has some IgE, an allergic person has an unusually large army of these IgE defenders -in fact, too many for their own good. This army of IgE antibodies attacks and engages the invading army of allergic substances of allergens. As is often the case in war, innocent bystanders are affected by this battle. These innocent bystanders are special cells called mast cells. When a mast cell is injured or irritated, it releases a variety of strong chemicals, including histamine, into the tissues and blood that promote allergic reactions. These chemicals are very irritating and cause itching, swelling, and fluid leaking from nearby cells. These allergic chemicals can cause muscle spasm and can lead to lung airway and throat tightening as is found in asthma and loss of voice. They are also what leads to the familiar hay fever or allergic rhinitis and common pink eye

alveolar bone the bone surrounding the roots of teeth
Alveolus A opening in your jaw-bone in which a tooth is attached
amalgam the most common material used for fillings, also called silver fillings; a mixture of mercury (app 50%), silver, tin, copper and zinc used for fillings

Clostridium welchii the most common cause of the dreaded gas gangrene,
E. coli, the common peaceful citizen of our colon and, upon occasion, a dangerous agent of disease, and
Streptococcus, the bacterium that causes the important infection of the throat strep throat. The term bacteria was devised in the 19th century by the German botanist Ferdinand Cohn (1828-98) who based it on the Greek bakterion meaning a small rod or staff. In 1853, Cohn categorised bacteria as one of three types of microorganisms -- bacteria (short rods), bacilli (longer rods), and spirilla (spiral forms). The term bacteria was preceded in the 17th century by the microscopic animalcules described by Antony van Leeuwenhoek (1632-1723).
Small living organisms, or microorganisms, that live in the bodies of animals, humans, and plants. Some types of bacteria cause disease
bad breath

Many things can cause bad breath. A major cause is decreased saliva. Saliva has a cleaning action that helps reduce or eliminate bad breath. When saliva decreases, bacteria can grow, causing bad breath. Everybody has bad breath from time to time, especially first thing in the morning. You also may have bad breath when you are hungry, when you are dieting, or after eating foods with a strong odor, such as garlic, onions, or pastrami.

bone Bone is the substance that forms the skeleton of the body. It is composed chiefly of calcium phosphate and calcium carbonate . It also serves as a storage area for calcium, playing a large role in calcium balance in the blood.
The 206 bones in the body serve several other purposes. They support and protect internal organs (for example, the skull protects the brain and the ribs protect the lungs). Muscles pull against bones to make the body move. Bone marrow, the soft, spongy tissue in the center of many bones, makes and stores blood cells.

The extensive procedures involved in complex rehabilitation require an extraordinary amount of time, effort, skill and laboratory collaboration for a successful outcome
composite common bonding mix of plastic and glass/ceramic particles; usually cured with light or chemicals
Coronal dentin dysplasia Coronal dentin dysplasia is a rare inherited dental defect that is also known as dentin dysplasia, type II. It is characterized by abnormal development (dysplasia) of the hard tissue (i.e., dentin) that is beneath the enamel, surrounds the pulp, and forms the major part of the teeth. In those with coronal dentin dysplasia, the baby teeth (primary or deciduous teeth) are brownish blue with a translucent "opalescence." (Opalescence refers to a milky, opal-like display of colors in reflected light [iridescence].) However, the permanent teeth appear normal in color.
As seen on dental x-ray imaging, the pulp chambers of the primary teeth--or the natural cavities that contain living pulp in the exposed portion of the teeth (crowns)--are obliterated by abnormal dentin. In addition, the pulp-containing canals within the roots of the teeth (root canals) are smaller than normal. The permanent teeth also have distinctive abnormalities of the pulp chambers. Coronal dentin dysplasia is transmitted as an autosomal dominant trait.
cosmetic dentistry aesthetic improvement of the color and shape of teeth performed by a general dentist
crown The part of your tooth above your gum: Also a crown is a dental appliance that replaces and covers the entire part of a tooth above the gum line. A crown may be made of gold, porcelain, or a combination of other man-made materials.
Crowns are used to:
* Repair teeth that have broken or decayed so much that they can no longer be treated with a filling.
* Improve the appearance of front permanent teeth (incisors) that are properly spaced but are rotated and look crooked.

filling

A filling is a substance that dentists use to replace a decayed or broken portion of a tooth. Commonly used substances for fillings include metal, alloy, plastic, porcelain, or a combination of materials (composite). Composite resins are made from plastic materials (glass and resin) and are usually similar to tooth color. They are often used on the front teeth where a natural appearance is important. Composite resins can sometimes also be used on the back teeth.

fistula tunnel conducting pus from one infection to the site of another; a mouth fistula is called a gum boil
Focal sclerosing osteomyelitis (condensing osteitis).This entity may be considered a true lesion of endodontic origin (LEO). The involved tooth will have an etiologic factor for low-grade, chronic inflammation such as a necrotic pulp, extensive restorative history or a crack. The patient may be asymptomatic or demonstrate a wide range of pulpal symptoms. EPT and thermal tests may or may not be responsive. Percussion and palpation testing may or may not be sensitive. Radiographically, the involved tooth will present with increased radiodensity and opacity around one or more of the roots. Evidence supporting consideration as a LEO is that 85% of these periradicular radiodensities resolve after endodontic therapy if they have a pulpal diagnosis of irreversible pulpitis.11
Focal osteopetrosis (periapical osteosclerosis).This entity is not a LEO. The patient will be asymptomatic. EPT and thermal testing are responsive and normal. Percussion and palpation testing will typically be non-sensitive. The involved tooth is usually a virgin tooth or has a normal pulp. Radiographically, the tooth will present with increased radiodensity and opacity around one or more of the roots. No treatment is necessary and the tooth should simply be monitored at periodic recall

Laser Dental Treatment

Laser dental treatment involves generating a beam of light into your mouth. The light enables your dentist to eliminate infected areas with accuracy. Sterilizing the affected area, the beam of light also closes off blood vessels. In most cases, patients rarely need anesthesia, meaning your dental visit will be relatively short.
Since the 1960s, lasers have been used on teeth and gums and because of technological advancements, lasers are now used globally. Laser dental treatments ensure low-power, meaning the device is gentle on the mouth. Most commonly used for removing old composite fillings and fumigating infected root canals, lasers can also be used for crown lengthening, bone shaping and oral surgery.
Benefits of Laser Dental Treatment
- Less noise than drilling
- Faster healing process
- Decreased risk of infection
- Less need for anesthesia
- Less need for multiple dental appointments
- Decreased sensitivity

local anesthesia elimination of the sensation of pain, in one part of the body by the surface application or regional injection of an anesthetic drug
mangaed care program whereby patient-dentist assignment and dentist reimbursement are administered by a separate, external organization
malocclusion

Malocclusion (often called crooked teeth or a “poor bite”) is the improper fit and alignment of the teeth and jaws. A common cause of malocclusion is teeth that have too much or too little room in the jaw.
Inherited traits, such as tooth and jaw size, mostly determine how well your teeth fit together. The most obvious sign of malocclusion is crooked or protruding teeth.
During the childhood and early teen years, orthodontists may straighten the teeth by changing the formation of the jaw, removing (extracting) selected teeth, or using fixed braces or removable appliances.
In adults, treatment with braces can straighten crooked teeth caused by a jaw problem, but any restructuring of the jawbone must be done with surgery, sometimes in combination with orthodontic treatment.

common term for tooth pulp which is the sensitive innermost portion of a tooth

nervous system

The sum total of the tissues that record and distribute information within a person, and does so by electrical and chemical means.

The nervous system has two distinct parts -- central and peripheral. The central part is made up of the brain and spinal cord. Together they are the central nervous system (CNS). The peripheral part of the nervous system is said to be peripheral because it is outside the CNS. The function of the peripheral nervous system is to transmit information back and forth between the CNS and the rest of the body.

The human nervous system contains approximately 10 billion nerve cells. These neurons are the basic building blocks of the nervous system. Neurons consist of the nerve cell body and various extensions from the cell body. These extensions, or processes, are the dendrites (branches off the cell that receive electrical impulses), the axon (the electrical wiring and conduit tube that conducts impulses), and specialized endings (terminal areas to transfer impulses to receivers on other nerves or muscles

nightguard plastic device that covers all of the upper or lower teeth; used to prevent wear caused by tooth grinding during sleep

Pain An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia . Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors.
Pain is also a term specifically used to denote a painful uterine contraction occurring in childbirth. The word "pain" comes from the Latin "poena" meaning a fine, a penalty

periodontal maintenance A series of simple measures performed by a dental professional that helps limit the effects and further development of periodontal disease. Some components of periodontal maintenance include soft tissue examination, plaque removal, and polishing of the teeth
periodontal pockets Toxins in plaque destroy the gum and connective tissues beneath the teeth, forming a pocket (space). As the disease progresses toward the bone, the pocket fills with plaque and infection. If not treated, the bone and connective tissue surrounding the tooth may become so severely damaged that the tooth will fall out or need to be extracted.
periodontal sites The areas around the tooth where deep pockets have formed
periodontist diagnoses and treats diseases of the tissues supporting and surrounding the teeth, especially periodontal, gum, disease
periodontitis

Periodontitis is an advanced form of gum disease in which the tissues and bones that support the teeth are damaged by the buildup of bacterial plaque. If periodontitis is not treated, teeth can become loose and may fall out or need to be removed. Treatment for periodontitis includes a cleaning method called root planing and scaling that removes plaque and tartar buildup both above and below the gum line. Antibiotics may be needed to help get rid of the infection. If gum disease is severe, surgery may be required.

permanent teeth the thirty-two adult teeth
Periradicular Tissues - Normal Normal periradicular tissues will be non-sensitive to percussion and palpation testing. Radiographically, periradicular tissues are normal with an intact lamina dura and a uniform periodontal ligament (PDL) space
Acute periradicular periodontitis Acute periradicular periodontitis occurs when pulpal disease extends into the surrounding periradicular tissues and causes inflammation. However, acute periradicular periodontitis may also occur as the result of occlusal traumatism. The patient will generally complain of discomfort to biting or chewing. Sensitivity to percussion is a hallmark diagnostic test result of acute periradicular periodontitis. Palpation testing may or may not produce a sensitive response. The PDL space may appear normal, widened, or there may be a distinct radiolucency
Chronic periradicular periodontitis When bacteria or bacterial products from a necrotic pulp or pulpless tooth slowly ingress into the periradicular tissues, the patient’s immune system may become involved in a chronic conflict. The resultant inflammatory process causes periradicular bone resorption that manifests as a periradicular radiolucency on the radiograph. Clinically, the patient is asymptomatic. Percussion and palpation testing produce non-sensitive responses
Subacute periradicular periodontitis (chronic periradicular periodontitis with symptoms). The patient will present with mild to moderate symptoms that may include spontaneous pain or discomfort on biting or chewing. The tooth may present with any pulpal diagnosis. Percussion testing produces a mild sensitive response and palpation testing may or may not be sensitive. Clinical symptoms are not as severe as acute periradicular periodontitis. Radiographically, the tooth will present anywhere from a normal periradicular appearance to a distinct radiolucency. These patients must receive endodontic treatment in a timely manner because the condition can quickly progress into acute periradicular periodontitis or an acute periradicular abscess
Acute periradicular abscess In this situation, bacteria have progressed into the periradicular tissues and the patient’s immune response cannot defend against the invasion. It is characterized by rapid onset, spontaneous pain, pus formation, and often swelling of the associated tissues. Depending upon the location of the apices of the tooth and muscle attachments, a swelling will usually develop in the buccal vestibule, on the lingual/palatal, or as a fascial space infection. Percussion testing produces a response that is usually exquisitely sensitive. This exaggerated response can help differentiate between acute periradicular periodontitis and the early stages of acute periradicular abscess. Palpation testing produces a sensitive response. Radiographically, the PDL space may be normal, slightly widened, or demonstrate a distinct radiolucency. This periradicular pathosis can occur with a necrotic pulp or a pulpless tooth that has been partially or definitely endodontically treated if continued bacterial contamination and/or leakage occurs
Chronic periradicular abscess (suppurative periradicular periodontitis). An inflammatory reaction to pulpal infection and necrosis characterized by gradual onset, little or no discomfort and intermittent discharge of pus through an associated sinus tract. Clinically, the patient is usually asymptomatic because the sinus tract allows drainage of any exudate from the periradicular tissues. EPT and thermal testing are non-responsive. Percussion and palpation testing usually produce non-sensitive responses. Radiographically, a periradicular lesion is associated with the involved tooth. This entity can also occur with a pulpless tooth that has been partially or definitely endodontically treated if continued bacterial contamination and/or leakage occurs
pit a small defect in the tooth enamel, usually found on the back teeth
placebo a treatment that works because of the patient's belief in it, not because of the actual physical change it produces
Pocket depth The size (depth) of a periodontal pocket, usually measured in millimeters
plaque

Soft deposits of bacteria and debris that collect on teeth. Plaque is a clear, sticky substance produced by the mouth. Plaque contains bacteria that produce acids and other chemicals that can damage the teeth, gums, and surrounding bone if the plaque is not removed. Plaque forms constantly, but it can be controlled by proper brushing and flossing.

pulp the nerves, blood vessels and connective tissue inside a tooth
pulp - normal A normal pulp is symptom free and will normally be responsive to the electric pulp tester (EPT). When evaluated by thermal testing, the normal pulp produces a positive response that is mild and subsides immediately when the stimulus is removed
Pulpless tooth A tooth from which the pulp has been removed. For example, a tooth with previous pulpotomy/pulpectomy/root canal debridement or previous root canal therapy should be recorded as a pulpless tooth for the pulpal diagnosis
pulp chamber the center or innermost portion of the tooth containing the pulp. Also knowl as pulp canal
PULPAL DIAGNOSIS Normal pulp - A clinical diagnostic category in which the pulp is symptom free and normally responsive to vitality testing.
Reversible pulpitis : A clinical diagnosis based upon subjective and objective findings indicating that the inflammation should resolve and the pulp return to normal
Irreversible pulpitis:A clinical diagnosis based on subjective and objective findings indicating that the vital inflamed pulp is incapable of healing.
Additional descriptions: Symptomatic,Lingering thermal pain, spontaneous pain, referred pain
Asymptomatic: No clinical symptoms but inflammation produced by caries,caries excavation, trauma, etc.
Pulp necrosis: A clinical diagnostic category indicating death of the dental pulp. The pulp is non-responsive to vitality testing.
Previously Treated: A clinical diagnostic category indicating that the tooth has been endodontically treated and the canals are obturated with various filling materials, other that intracanal medicaments.
Previously Initiated Therapy: A clinical diagnostic category indicating that the tooth has been previously treated by partial endodontic therapy (e.g. pulpotomy, pulpectomy).
Pulpal necrosis Necrosis is a histologic term that denotes death of the pulp. Teeth with total pulpal necrosis are usually asymptomatic unless inflammation has progressed to the periradicular tissues. The pulp will not respond to the EPT and if using a digital EPT, this result should be reported as no response (NR) over 80. The pulp will not respond to thermal tests. The dental record entry for this pulpal diagnosis should be pulpal necrosis

pulp cap a medicated covering over a small area of exposed pulp
pulpitis inflammation of the pulp; a common cause of a toothache
pulpitis - reversible Caries, cracks, restorative procedures or trauma may cause a pulp to become inflamed. The patient’s chief complaint is usually of an exaggerated response to thermal stimulus but once the stimulus is removed, the discomfort does not linger. EPT results are responsive
pulpitis - irreversible If the inflammatory process progresses, irreversible pulpitis can develop. Patients may have a history of spontaneous pain and complain of an exaggerated response to hot or cold that lingers after the stimulus is removed. EPT results are usually responsive. The involved tooth will often present with a history of an extensive restoration and/or caries.
In certain cases of irreversible pulpitis, the patient may arrive at the dental clinic sipping a glass of ice water or applying ice to the affected area. In these cases, cold actually alleviates the patient’s pain as the dental pulp has developed allodynia and is hyperalgesic. Normal body temperature is now causing the nociceptors in the pulp to discharge.10 Removal of the cold causes return of symptoms and can be used as a diagnostic test.
Irreversible pulpitis can also present as an asymptomatic condition. Internal resorption and hyperplastic pulpitis (pulp polyp) are examples of asymptomatic irreversible pulpitis

Sjögren's syndrome

is a disease in which the immune system attacks the body's moisture-producing glands. This disease may cause the tear and saliva glands to become scarred and damaged, and can cause exceptional dryness in the eyes and mouth.
Sjögren's syndrome is most common in women who are older than 40.
People with Sjögren's syndrome usually have a dry mouth that makes swallowing difficult and dry eyes that cause eye pain. In severe cases, they may have scarring of the covering of the eye (cornea). Sjögren's syndrome may also cause fatigue, joint pain, and problems with the function of vital organs.
Although there currently is no cure for Sjögren's syndrome, treatment of symptoms can offer relief for many people. For example, artificial tears can be used to moisten the eyes, and mouth lubricants and saliva substitutes can help to moisten the mouth and throat.

Strep throat

Strep throat is a bacterial infection of the tissues in the back of the throat (pharynx) and the tonsils or adenoids. The tissues become irritated and inflamed, causing a sudden, severe sore throat
Symptoms of strep throat include a sore throat with:
* Fever of 101° F (38.3° C) or higher.
* Pain and difficulty swallowing.
* White or yellow spots or coating on the throat and tonsils.
* Swollen lymph nodes in the neck.
In children, strep throat may also cause body aches, headache, stomachache, nausea, vomiting, or listlessness. Strep throat does not occur with cold symptoms, such as sneezing, runny or stuffy nose, or cough.
While strep throat usually resolves on its own in a few days, it is treated with antibiotics to prevent complications, such as rheumatic fever, from occurring.

Tissue A tissue in medicine is not like a piece of tissue paper. It is a broad term that is applied to any group of cells that perform specific functions. A tissue in medicine need not form a layer. Thus,The bone marrow is a tissue;

Connective tissue consists of cells that make up fibers in the framework supporting other body tissues; and Lymphoid tissue is the part of the body's immune system that helps protect it from bacteria and other foreign entities.

Tooth

The structures within the mouth that allow for biting and chewing. Teeth have different shapes, depending on their purpose. The sharp canine and frontal teeth allow for biting, while the flattened, thick molars in the back of the mouth provide grinding surfaces for masticating food. All teeth have essentially the same structure: a hard crown above the gum line, which is attached to two or four roots by a portion called the neck. The roots are covered with a very thin layer of bone, and keep the tooth embedded in the bones of the jaw. The exposed exterior of the tooth is covered with tough enamel. Under the enamel is a thick layer of dentin, and in the center is the pulp. Blood vessels and nerves are found within the pulp

tooth bud early embryonic structure that becomes a tooth
tooth decay

the combination of bacteria and food causes tooth decay. A clear, sticky substance called plaque that contains bacteria is always forming on your teeth and gums. As the bacteria feed on the sugars in the food you eat, they make acids. The acids attack the teeth for 20 minutes or more after eating. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay. Tooth decay is the process that results in a cavity (dental caries).If not treated, tooth decay can cause infection and tooth loss.
