Dentistry has several systems of notation to identify teeth. In the universal system of notation , the deciduous maxillary central incisors are designated by a letter written in uppercase. [ 3 ] The right deciduous maxillary central incisor is known as "E", and the left one is known as "F".
Discoloured teeth - teeth may be amber, brown, blue or opalescent Bulbous shape to the tooth crown due to cervical constriction Tooth wear /Non-carious tooth surface loss (NCTSL) - due to the poorly mineralised dentine, the enamel of the tooth is unsupported and subsequently shears or chips off as it is subjected to biting forces.
Relative incidence of odontogenic cysts. [1] Dentigerous cyst is labeled at top right. A dentigerous cyst, also known as a follicular cyst, is an epithelial-lined developmental cyst formed by accumulation of fluid between the reduced enamel epithelium and the crown of an unerupted tooth.
Triangular ridges are those that project from the cusp tips of premolar and molars to the central groove. Transverse ridges are formed by the union of two triangular ridges on posterior teeth. The joining of buccal and lingual triangular ridges is usually named as an example. The oblique ridge is found on the occlusal surfaces of maxillary molars.
Cross-section of a tooth. B is dentin. Dentin (/ ˈ d ɛ n t ɪ n / DEN-tin) (American English) or dentine (/ ˈ d ɛ n ˌ t iː n / DEN-teen or / ˌ d ɛ n ˈ t iː n / DEN-TEEN) (British English) (Latin: substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth.
Dentin formation, known as dentinogenesis, is the first identifiable feature in the crown stage of tooth development. The formation of dentin must always occur before the formation of enamel. The different stages of dentin formation result in different types of dentin: mantle dentin, primary dentin, secondary dentin, and tertiary dentin. [31]
The pathological wear of the tooth surface can be caused by bruxism, which is clenching and grinding of the teeth. If the attrition is severe, the enamel can be completely worn away leaving underlying dentin exposed, resulting in an increased risk of dental caries and dentin hypersensitivity. It is best to identify pathological attrition at an ...
Molar incisor hypomineralisation (MIH) is a type of enamel defect affecting, as the name suggests, the first molars and incisors in the permanent dentition. [1] MIH is considered a worldwide problem with a global prevalence of 12.9% and is usually identified in children under 10 years old. [2]
