The pulp has a background similar to that of dentin because both are derived from the dental papilla of the tooth germ. During odontogenesis, when the dentin forms around the dental papilla, the innermost tissue is considered pulp. [8] SDEO: Dental pulp of a stained and decalcified tooth. [9] There are 4 main stages of tooth development: Bud stage
A cusp is an elevation on an occlusal surface of posterior teeth and canines. It contributes to a significant portion of the tooth's surface. Canines have one cusp. Maxillary premolars and the mandibular first premolars usually have two cusps. Mandibular second premolars frequently have three cusps--- one buccal and two lingual.
Gingival sulcus, also known as gingival crevice, refers to the space between the tooth surface and the sulcular epithelium. At the free gingival margin, the sulcular epithelium is continuous with the gingival epithelium. Both the attached gingivae and the free gingivae are included as part of the gingival epithelium.
Radiographs recommended: periapical and occlusal exposures (to rule out the possible presence of a root fracture or a luxation injury) Radiograph of lip or cheek to search for tooth fragments or foreign materials; Enamel-dentin fracture A fracture is confined to enamel and dentin with loss of tooth structure, but exposing the pulp
In vertebrates, an odontoblast is a cell of neural crest origin that is part of the outer surface of the dental pulp, and whose biological function is dentinogenesis, which is the formation of dentin, the substance beneath the tooth enamel on the crown and the cementum on the root.
When space exists between the contacts of the maxillary central incisors, the condition is referred to as a diastema or "gap tooth." One frequent cause of the space is the presence of a large labial frenum from the upper lip extending near the teeth. Treatment depends upon the cause and extent of the gap.
Alveolar mucosa, the lining between the buccal and labial mucosae. It is a brighter red, smooth, and shiny with many blood vessels, and is not connected to underlying tissue by rete pegs. [6] Buccal mucosa, the inside lining of the cheeks; part of the lining mucosa. Labial mucosa, the inside lining of the lips; part of the lining mucosa. [7]
The partial scoring system is based on the surface area affected. Within a sextant (i.e. teeth in mouth divided into 6 parts), the most severely affected tooth surface (buccal, occlusal or lingual/palatal)(see dental terminology) is recorded according to the severity of the wear (see Table 1). A cumulative score is then matched to a risk level ...
