Premature loss of permanent dentition from caries, trauma, iatrogenic damage or developmental abnormalities. The tooth of choice to replace a tooth missing in the anterior maxillary region is the maxillary second premolars. Poor prognosis first permanent molars can be replaced with third molars
Dental restoration, dental fillings, or simply fillings are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants. [1]
Mandibular teeth erupt in the following order: (1) first molar (2) central incisor, (3) lateral incisor, (4) canine, (5) first premolar, (6) second premolar, (7) second molar, and (8) third molar. Since there are no premolars in the primary dentition, the primary molars are replaced by permanent premolars. [48]
The dentinoenamel junction or dentin-enamel junction (DEJ) [1] is the boundary between the enamel and the underlying dentin that form the solid architecture of a tooth.. It is also known as the amelo-dentinal junction, [2] or ADJ.
Preformed metal crowns are now recommended as the optimum restoration for managing carious primary molars. There are multiple randomised controlled trials that have shown the Hall Technique to be superior to other methods for managing decay in baby teeth, [ 1 ] but there is a lack of evidence to conclude that the Hall Technique is superior to ...
Angle's Classification is devised in 1899 by father of Orthodontic, Dr Edward Angle to describe the classes of malocclusion, widely accepted and widely used since it was published. Angle's Classification is based on the relationship of the mesiobuccal cusp of the maxillary first molar and the buccal groove of the mandibular first molar. [3]
In dental anatomy, the cementoenamel junction (CEJ) is the location where the enamel, which covers the anatomical crown of a tooth, and the cementum, which covers the anatomical root of a tooth, meet.
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 ]
