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.
The diameter and density of the tubules are greatest near the pulp. [10]: 152 Tapering from the inner to the outermost surface, they have a diameter of 2.5 μm near the pulp, 1.2 μm in the middle of the dentin, and 0.9 μm at the dentino-enamel junction. Their density is 59,000 to 76,000 per square millimeter near the pulp, whereas the density ...
In dental anatomy, the gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for groove ) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin .
There frequently are three pulp horns in this tooth. [11] In nearly all maxillary central incisors, there is one canal with one apex. [16] During root canal therapy, access into the pulp is frequently located centrally on the lingual surface between the incisal edge and the cingulum.
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
Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic occlusion refers to occlusal contacts made when the jaw is moving. [ 1 ] The masticatory system also involves the periodontium , the TMJ (and other skeletal components) and the neuromusculature, therefore the tooth contacts should not be looked ...
In the posterior teeth, both in upper and lower jaw, the lingual height of contour is found at the middle third of the inner surface of the tooth. The lower second premolar proposes an exception as its height of curvature in inner surface is located in the occlusal third of the inner surface. In addition, the curvature of CEJ is more pronounced ...
