Gomphosis: Gomphosis, also known as the dental-alveolar joint, is a joint that binds the teeth to bony sockets (dental alveoli) in the maxillary bone and mandible. The fibrous connection between a tooth and its socket is a periodontal ligament.Human tooth: The human teeth function in mechanically breaking down items of food by cutting and crushing them in preparation for swallowing and digestion. There are four different types of teeth, namely incisors, canines, molars and premolars.Alveolar osteitisUtkal Prantiya Marwari Yuva ManchTooth loss: Tooth loss is a process in which one or more teeth come loose and fall out. Tooth loss is normal for deciduous teeth (baby teeth), when they are replaced by a person's adult teeth.Cingulate cortex: The cingulate cortex, also known as limbic cortex, is a part of the brain situated in the medial aspect of the cerebral cortex. The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the cingulate sulcus.Neonatal line: The neonatal line is a particular band of incremental growth lines seen in histologic sections of a deciduous tooth. It belongs to a series of a growth lines in tooth enamel known as the Striae of Retzius.Apical delta: Apical delta refers to the branching pattern of small accessory canals and minor foramina seen at the tip or apex of some tooth roots.Talon cuspOcular prosthesisIntraosseous eruption: Intraosseous eruption involves the formation of root of a tooth which allows the tooth to being eruption from the bone. This phase precedes the Supraosseous Eruption phase which consists of Infragingival eruption and Supragingival Eruption.
