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 deciduous maxillary second molar is the most likely deciduous tooth to have an oblique ridge. In the universal system of notation, the deciduous maxillary second molars are designated by a letter written in uppercase. The right deciduous maxillary second molar is known as "A", and the left one is known as "J".
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. Maxillary molars have two buccal cusps and two lingual cusps. A fifth cusp that may form on the maxillary first molar is known as the cusp of Carabelli ...
For maxillary first molars, the mean root trunk length is 3-4 mm on the buccal aspect, and 4-5 mm on the mesial aspect and 5-6 mm on the distal aspect. [2] As with mandibular molars, the root trunk lengths for maxillary second and third molars are either the same or slightly greater than for first molars, although the roots may be fused.
A tooth that has experienced trauma may become loose due to the periodontal ligament becoming damaged or fracture to the root of the tooth. Splinting ensures that the tooth is held in the correct position within the socket, ensuring that no further trauma occurs to enable healing. [37] A splint can either be flexible or rigid.
A cusp is a pointed, projecting, or elevated feature. In animals, it is usually used to refer to raised points on the crowns of teeth. The concept is also used with regard to the leaflets of the four heart valves. The mitral valve, which has two cusps, is also known as the bicuspid valve, and the tricuspid valve has three cusps.
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
An enamel fracture is when the outermost layer of the tooth is cracked, without damaging the inner layers including the dentine or pulp. This can happen from trauma such as a fall where the teeth are impacted by a hard object causing a chip to occur. Enamel fracture of tooth 11 on the incisal, biting, surface
