The side of a tooth adjacent to (or the direction toward) the oral cavity, as opposed to buccal, labial or vestibular, which refer to the side of a tooth adjacent to (or the direction toward) the inside of the cheek, lips or vestibule respectively. Oral includes both palatal and lingual.
Taurodontism is defined as the enlargement of pulp chambers with the furcation area being displaced toward the apex of the root of a tooth. It cannot be diagnosed clinically and requires radiographic visualization since the crown of a taurodontic tooth appears normal and its distinguishing features are present below the alveolar margin.
Cementum is a specialized bone like substance covering the root of a tooth. [15] It is approximately 45% inorganic material (mainly hydroxyapatite), 33% organic material (mainly collagen) and 22% water. Cementum is excreted by cementoblasts within the root of the tooth and is thickest at the root apex. Its coloration is yellowish and it is ...
The tooth bud (sometimes called the tooth germ) is an aggregation of cells that eventually forms a tooth and is organized into three parts: the enamel organ, the dental papilla and the dental follicle. [3] The enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium. [3]
Resorption of the root of the tooth, or root resorption, is the progressive loss of dentin and cementum by the action of odontoclasts. [4] Root resorption is a normal physiological process that occurs in the exfoliation of the primary dentition .
The impact from the primary tooth will be transferred to the permanent tooth that may have its roots formed, thus causing a bend or curvature of the permanent tooth root. [5] It is noted that rather than the force of the impact, the direction in which the impact occurs has a more significant effect on dilaceration formation.
Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain. One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament ...
The system uses two numbers to define each tooth. One to specify the quadrant, and one to specify the tooth within that quadrant. Orientation of the chart is traditionally "dentist's view", i.e. patient's right corresponds to notation chart left. The designations "left" and "right" on the chart below correspond to the patient's left and right.
