The first of these, the deciduous or milk dentition, occupies the same position in the dental arch as the subsequent successor teeth. semi-precision attachment: A laboratory fabricated rigid metallic extension of a fixed or removable partial denture that fits into cast restoration, allowing some movement between the components; attachments with plastic components are often called semi-precision attachments. It is intended to control local irritational factors. sealant: A resinous material designed to be applied to the occlusal surfaces of posterior teeth to prevent occlusal caries. Sequence of eruption of the primary dentition. The mandibular and maxillary first molars emerge between 16 and 19months, and the baby has a smile with gaping holes in the four corners of his mouth, imitating an older adult who would be partially edentulous. Centric Relation P3 and P4. Hyuk-Jae Edward Kwon, Rulang Jiang, in Reference Module in Biomedical Sciences, 2018. (American College of Prosthodontics; The Glossary of Prosthodontic Terms). A wad of chewing tobacco is sometimes wedged between the cheek and the buccal surfaces of the molars of American baseball players. Complete Dentures Single Dentures Opposing Natural Dentition In gingival health, the coronal portion of the sulcular epithelium may also be keratinized. temporary: a restoration or prosthesis placed for a shorter time interval for use while a definitive restoration or prosthesis is being fabricated see interim and provisional. WebCentric occlusion refers to a position of maximal, bilateral, balanced contact between the cusps of the maxillary and mandibular arches. The development of the human dentition evolves in a predictable pattern that can be divided into six different stages, starting from birth and ending with the complete adult dentition. bounded tooth space: See tooth bounded space. There is nothing wrong with the correction of an acquired malocclusion, but the doctor and clinic staff will not be an accomplice to fraud. The canine usually projects beyond the occlusal plane of the regular tooth row and a diastema is frequently evident between the upper lateral incisor and the canine. odontogenic cystCyst derived from the epithelium of odontogenic tissue (developmental, primordial). Webn. comprehensive oral evaluation: See evaluation. keratin: A protein present in all cuticular structures of the body, such as hair, epidermis and horns. Current Dental Terminology (CDT): The ADA reference manual that contains the Code on Dental Procedures and Nomenclature and other information pertinent to patient record keeping and claim preparation by a dental office; published biennially (e.g., CDT 2020). Click a letter to jump to that section. It is based on quadrants and identifies each tooth individually as to class (denoted by a single letter) and order of its location for that class (denoted by a number). panoramic radiograph: An extraoral projection whereby the entire mandible, maxilla, teeth and other nearby structures are portrayed on a single image, as if the jaws were flattened out. site: A term used to describe a single area, position, or locus. inlay: A fixed intracoronal restoration; a fixed dental restoration made outside of a tooth to correspond to the form of the prepared cavity, which is then luted to the tooth. fixed prosthesisNon-removable dental prosthesis which is solidly attached to abutment teeth, roots or implants. graft: A piece of tissue or alloplastic material placed in contact with tissue to repair a defect or supplement a deficiency. discectomy: Excision of the intra-articular disc of a joint. The primary dentition consists of 20 teeth (Figure 1). bilateral: Occurring on, or pertaining to, both right and left sides. Although cognitive function and coordination may be modestly impaired, ventilatory and cardiovascular functions are unaffected. Dental floss often gets stuck in interproximal areas. decay: The lay term for carious lesions in a tooth; decomposition of tooth structure. canal: A relatively narrow tubular passage or channel. orthognathic: Functional relationship of maxilla and mandible. rubber dam: A barrier technique used to prevent the passage of saliva or moisture, or to provide an isolated operative field. clenching: The clamping and pressing of the jaws and teeth together in centric occlusion, frequently associated with psychological stress or physical effort. cleft palate: Congenital deformity resulting in lack of fusion of the soft and/or hard palate, either partial or complete. on the periodontally-borne, fixed section of the restoration (mainly in the form of crowns or bridges on teeth and implants). Tim D. White, Pieter A. Folkens, in Human Osteology (Third Edition), 2012. pontic: The term used for an artificial tooth on a fixed partial denture (bridge). Anchorage is resistance to unwanted tooth movement.4 The object is to create a platform from which an orthodontic force may be exerted that will move the active tooth and only minimally move the anchorage tooth or teeth (unless one also wants to move the anchorage). As already indicated, the number of premolars in each quadrant is not constant for all higher primates but divides into two distinct patterns along evolutionary lines. adhesion: State in which two surfaces are held together by chemical or physical forces or both with or without the aid of an adhesive. Webopposing arch, in the buccolingual or labiolingual direction. arch evulsion: Separation of the tooth from its socket due to trauma. anxiolysis: See definition under anesthesia. The stellate cellular shape is maintained in areas of secondary fibrosis10 In the mandibular myxoma, the nuclei were ovoid and vesicular, with one or more indistinct nuclei, and the mitotic rate was low.26 In malignant neoplasms, there is higher cellularity, with larger, more pleomorphic tumour cells.10 No areas of bone or cartilage formation should be noted.10,11 Extensive resorption of adjacent bone may be seen, i.e. The noble metal classification system has been adopted as a more precise method of reporting various alloys used in dentistry. The most common form is a mesiodens, which forms between the two maxillary central incisors (Hyun et al., 2009), but supernumerary teeth can also be found in the premolar and at the posterior end of the dentition (Hyun et al., 2008; Kawashita and Saito, 2010). The anterior portion of molar and premolar crowns and the medial parts of canines and incisors are called the mesial parts of these teeth. transosteal (transosseous): Device with threaded posts penetrating both the superior and inferior cortical bone plates of the mandibular symphysis and exiting through the permucosa. In the adult, note the number of premolars in each quadrant, the diastema between the lateral incisor and the canine, and the cusp pattern of the molars. supernumerary teeth: Extra erupted or unerupted teeth that resemble teeth of normal shape. extracoronal: Outside the crown of a tooth. scaling: Removal of plaque, calculus, and stain from teeth. therapeutic: Of or pertaining to therapy or treatment; beneficial. Complete Dentures Single Dentures Opposing Natural Dentition These studies (Swindler, 2002) have shown that premolars are lost from anterior to posterior along the tooth row and that the premolars retained in living primates are the last of the original premolars. operculum: The flap of tissue over an unerupted or partially erupted tooth. 39501984 Dentistry Designation System for Tooth and Areas of the Oral Cavity) is designed to identify areas of the oral cavity as well as uniquely number permanent and primary dentition. May involve the placement of an artificial apical barrier prior to nonsurgical endodontic obturation. Removable restoration saddles are often connected by a metal base (frequently fabricated using CrCo), in the upper jaw possibly using a large connector (transverse connector) and in the lower jaw using a lingual bar. These agents are added to graft material or used alone to effect acceleration of healing or regeneration in hard and soft tissue surgical procedures. As indicated here the deciduous cheek teeth are premolars even though they are frequently called molars. The sequence and age of dental eruption are discussed with growth and development (see also Dental and skeletal maturation above). The interim period of time for a restoration, a prosthesis or a procedure, is determined by the clinical and professional judgment of the dentist. The innervation and vascular supply to the teeth as well as the morphology of the supporting gingival and periodontal structures are similar in all primates, including humans. Figure 2.2.

Various versions of partial restorations supplement existing teeth and/or implants. Delivery of an anesthesia inducing agent by a dentist or other health care practitioner is regulated by state dental boards. local anesthesiathe elimination of sensation, especially pain, in one part of the body by the topical application or regional injection of a drug. complete series: A set of intraoral radiographs usually consisting of 14 to 22 periapical and posterior bitewing images intended to display the crowns and roots of all teeth, periapical areas and alveolar bone crest (source: FDA/ADA radiographic guidelines). direct restoration: A restoration of any type (e.g., filling; crown) fabricated inside the mouth. allogenic: Belonging to the same species, but genetically different. core buildup: the replacement of a part or all of the crown of a tooth whose purpose is to provide a base for the retention of an indirectly fabricated crown. Blood vessels enter the pulp cavity through an apical opening. behavior management: Techniques or therapies used to alter or control the actions of a patient who is receiving dental treatment. A few rare syndromes are associated with premature eruption of the primary dentition. ScienceDirect is a registered trademark of Elsevier B.V. ScienceDirect is a registered trademark of Elsevier B.V.

See exostosis. 9-3, A) (requires light force). The canine tooth is abbreviated C and since there is only one canine in each quadrant it is written either C or C1. The primary teeth are smaller and have a shallower anatomy than their successors. See precision attachment. TMJD: See temporomandibular joint dysfunction. reimplantation, tooth: The return of a tooth to its alveolus. Extrusion: tooth is moved out of the alveolus (Fig. transplantation of tooth: Transfer of a tooth from one socket to another, either in the same or a different person.
