Detailed Dental Terminologies Dr Noor Al Murtada Complete denture  Is a removable dental prosthesis that replaces all the natural teeth and their associated structures. Also called full denture. Partial denture  Is a removable dental prosthesis that restores one or more, but less than all, of the natural teeth and is supported by the teeth or the soft tissue.  There are different designs for partial dentures according to the places of missing teeth for each patient. Dental crown Is a fixed tooth-shaped "cap" that is placed over a prepared tooth.  It covers the prepared tooth to restore its shape and size, strength, and improve its appearance.  A dental crown may be needed in the following situations:  To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth  To restore an already broken tooth or a tooth that has been severely worn down  To cover and support a tooth with a large filling when there isn't a lot of tooth left  To hold a dental bridge in place  To cover severely discolored teeth  To make a cosmetic modification Bridge  Is a fixed prosthesis that consists from two teeth or more. Dental bridges usually is created by one or more missing teeth  It is made up of two or more crowns for the teeth on either side of the gap (missing tooth).  These two or more teeth are called abutment teeth.  There are different types of the bridges. Dental implant  Is a surgical component that interfaces (osseointegrate) with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, and denture.  Cavities (caries): Bacteria attach and damage the enamel and deeper structures of teeth. Most cavities occur on molars and premolars.  Tooth decay: A general name for disease of the teeth, including cavities and caries. Periodontitis vs Gingivitis  Gingivitis: Inflammation of the surface portion of the gums, around and between the crowns of the teeth. Plaque (A sticky, colorless film made of bacteria and the substances they secrete. Plaque develops quickly on teeth after eating sugary food, but can be easily brushed off) buildup can lead to gingivitis.  Periodontitis: Inflammation of the deeper structures of the teeth (periodontal ligament, jawbone, and cementum). Poor oral hygiene is usually to blame and accumulation of tartar (If plaque is not removed, it mixes with minerals to become tartar, a harder substance). Orthodontics  Is the specialty of dentistry that is concerned with the treatment of improper bites and crooked teeth.  It can help fix the patient's teeth and set them in the right place.  It usually use braces (usually made from metal (fig 1) or plastic (fig 2)) or clear aligners (invisalign in fig 3) to set the patient's teeth.  Invisalign aligners are the clear alternative to metal braces for adults and teens. These clear aligners are the virtually invisible way to improve the smile Fig 1 Fig 2 Fig 3 Dental filling  Is a material that the dentist uses to fill a cavity after removing any tooth decay.  Different materials are used for filling. Amalgam (silver metal) usually for posterior teeth, and tooth coloured filling for anterior teeth or posterior. Inlay Night Guard  Is customized, worn daily for Bruxism.  Like any personal care item, it requires regular cleaning to prevent damage to the appliance and growth of bacteria.  Bruxism: is a condition in which you grind, gnash or clench your teeth.  If you have bruxism, you may unconsciously clench your teeth when you're awake (awake bruxism) or clench or grind them during sleep (sleep bruxism). Sleep bruxism is considered a sleep-related movement disorder. Mamelons, why? Where? Primary (deciduous) vs Permanent (adult) Dentition The anatomy of primary teeth is very much similar to the permanent except:  They are whiter  The crowns are shorted  They are smaller  Roots are longer and slender Note:  Permanent teeth consists of 8 incisors, 4 canines, 8 premolars and 12 molars  Some teeth have either one root, two roots, or three roots  Contact area or contact point: area or point where that touches the adjacent tooth in the same arch; contact point in the anterior teeth, and contact area in the posterior teeth.
