D

Deep Sedation–a drug-induced depression of consciousness during which patients cannot be easily aroused but respond purposefully following repeated or painful stimulation. The ability to independently maintain ventilatory function may be impaired. Patients may require assistance in maintaining a patent airway, and spontaneous ventilation may be inadequate. Cardiovascular function is usually maintained.
DDS – Doctor of Dental Surgery.

G

General Anesthesia–a drug-induced loss of consciousness during which patients are not arousable, even by painful stimulation. The ability to independently maintain ventilatory function is often impaired. Patients often require assistance in maintaining a patent airway, and positive pressure ventilation may be required because of depressed spontaneous ventilation or drug-induced depression of neuromuscular function. Cardiovascular function may be impaired.
Gingiva – The soft tissue that covers the jawbone. Also referred to as the gums.
Gingivectomy – The surgical removal of gingiva (gum).
Gingivitis – An inflammation or infection of the gingiva (gum tissue); the initial stage of gum disease.
Gingivoplasty – A surgical procedure to reshape or repair the gingiva (gum).
Gluma – Gluma is a desensitizing chemistry for treating and preventing dentinal hypersensitivity. Gluma’s patented (Heraeus Kulzer) glutaraldehyde/HEMA (2-hydroxyethyl methacrylate) formula acts in seconds to seal dentinal tubules, preventing the fluid shifting recognized as the primary cause of localized hypersensitivity. Gluma also inhibits the growth of bacteria, which are also indicated as a cause of sensitivity. Gluma’s patented formula works within the dentinal tubule complex by reacting with protein fluids to form a physiological seal within the tubules. No surface layer is formed, making Gluma ideal for use under all indirect restorations.
Graft – A piece of gum tissue or synthetic material placed in contact with tissue to repair a defect or supplement a deficiency.
Gum – See “Gingiva.”
Gum disease – See “Periodontal disease.”

H

Hypersensitivity – Typically refers to tooth pain that is caused very easily and with a stimulus that normally would elicit no feeling.

I

Immediate denture – A denture constructed for immediate placement after removal of teeth.
Impacted tooth – An unerupted or partially erupted tooth whose complete eruption is unlikely.
Implant – An artificial device, usually made of a metal alloy or ceramic material, that is implanted within the jawbone as a means to attach an artificial crown, denture, or bridge.
Incisal edge – The biting edge of front teeth. Compare to occlusal surface.
Incisors – The four front teeth referred to as central and lateral incisors, located in the upper and lower jaws and used to cut and tear food. The central incisors are the two teeth in the middle of the mouth and the lateral incisors are next to the central incisor, one on each side.
Indirect pulp cap – A procedure in which the nearly exposed pulp is covered with a protective dressing to protect the pulp from additional injury and to promote healing and repair via formation of secondary dentin.
Indirect restoration – Restorations in dental terminology refer to repairs of teeth, like fillings; however, there are many ways to repair teeth in addition to fillings. Fillings, whether they are gold foil, silver/amalgam, or tooth-colored composite fillings are all placed directly into teeth and are completed as one continuous procedure – these are direct restorations. Indirect restorations include inlays, onlays, and crowns. These types of restorations are made after the tooth has been shaped (also called prepared), and are cemented or bonded in as a separate procedure – these are indirect restorations.
Inlay – A strong, durable material made outside the mouth used to replace part of a tooth (can be metallic or tooth-colored) and is cemented or bonded once it is constructed. Compare to a filling which is packed into the tooth. An inlay is an indirect restoration.
Interproximal – The area between two adjacent teeth.
Intracoronal – The area inside the crown of a tooth.
Intraoral – The inside of the mouth.
Intravenous – A technique of administration in which the anesthetic agent is introduced directly into the patient’s venous system.

L

Labial – The area pertaining to or around the lip.
Laser Cavity Detection – A laser diode provides pulsed light of a defined wave-length that is directed onto the tooth. When the light meets a change in tooth substance, it stimulates fluorescent light of a different wavelength. This is translated through the handpiece into an acoustic signal, and the wavelength is then evaluated by an appropriate electronic system.
Lingual – The area pertaining to or around the tongue. Also referring to the tongue-side as opposed to the cheek-side. See “Buccal, Facial.”
Local anesthetic – The injection given in the mouth to numb the areas where a tooth or area requires a dental procedure. Often referred to as Novocain.

M

Malocclusion – The improper alignment of teeth.
Mandible – The lower jaw.
Maryland bridge – The name that has become synonymous with any resin bonded fixed partial denture (bridge). Typically, a Maryland bridge does not require as much shaping for the anchor teeth like a conventional bridge.
Mastication – The act of chewing.
Maxilla – The upper jaw.
Mesial – Refers to the side of tooth, between teeth, towards the front. See “Distal.”
Metals, classification of – The noble metal classification system has been adopted as a more precise method of reporting various alloys in dentistry commonly used in crowns, bridges and dentures. These alloys contain varying percentages of gold, palladium and/or platinum.
high noble contains 60% or more of gold, palladium, and/or platinum (with at least 40% gold) noble contains 25% or more of gold, palladium and/or platinum predominantly base contains less than 25% gold, palladium and/or platinum Molars – The broad back teeth, used for grinding food are considered the largest teeth in the mouth. In adults there are a total of twelve molars (including the four wisdom teeth, or third molars), three on each side of the upper and lower jaws. Ideally, a healthy mouth usually does not include wisdom teeth.
Minimal Sedation – A minimally depressed level of consciousness, produced by a pharmacological method, that retains the patient’s ability to independently and continuously maintain an airway and respond normally to tactile stimulation and verbal command. Although cognitive function and coordination may be modestly impaired, ventilatory and cardiovascular functions are unaffected.
Moderate Sedation–a drug-induced depression of consciousness during which patients respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation. No interventions are required to maintain a patent airway, and spontaneous ventilation is adequate. Cardiovascular function is usually maintained.

N

Nitrous oxide – A controlled mixture of nitrogen and oxygen gases (N2O) that is inhaled by the person in order to decrease sensitivity to pain and/or anxiety. Also referred to as laughing gas.
Novocain – A generic name for the many kinds of anesthetics used in the dental injection, such as Xylocaine, Lidocaine, Novocain and other local anesthetics. Novocain has not actually been used for decades. See “Local Aanesthetic.”

O

Occlusal x-ray – An intraoral x-ray taken with the film held between the teeth in biting position.
Occlusal surface – The chewing surface of the back teeth. Compare to incisal edge.
Occlusion – Any contact between biting or chewing surfaces of upper and lower teeth.
Onlay – A strong, durable material made outside the mouth used to replace part of a tooth, including one or more points or cusps of the tooth, (can be metallic or tooth-colored) and is cemented or bonded once it is constructed. Compare to a filling which is packed into the tooth. Also compare to an inlay, which does not replace a cusp. An onlay is an indirect restoration.
Oral surgery – The removal of teeth and the repair and treatment of other oral problems, such as tumors and fractures.
Orthodontics – A specialized branch of dentistry that corrects malocclusion and restores the teeth to proper alignment and function. There are several different types of appliances used in orthodontics, one of which is commonly referred to as braces.

Retrograde filling – A method of sealing the root canal by preparing and filling it from the root tip, generally done at the completion of an apicoectomy.
Root – The part of the tooth below the crown, normally encased in the jawbone. It is made up of dentin, includes the root canal, and is covered by cementum.
Root canal – The hollow part of the tooth’s root. It runs from the tip of the root into the pulp.
