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 ]
Molar distalization is a process in the field of Orthodontics which is used to move molar teeth, especially permanent first molars, distally (backwards) in an arch. This procedure is often used in treatment of patients who have Class 2 malocclusion . [ 1 ]
The Hall technique can also be used with permanent first molars in some cases where prognosis is poor, such as where first permanent molars are hypomineralised, carious with poor prognosis but to be maintained until full eruption of second molars, or for cuspal coverage of endodontically treated teeth in minors with compliance issues preventing ...
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
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]
For an ankylosed molar, distal teeth can respond to orthodontic force normally and thus can be used as substitute if the ankylosed tooth is extracted [citation needed]. Surgical luxation is sometimes used to break the ankylosis bridge to restore occlusion [citation needed]. For a case of PFE, the targeted molar can only be treated by osteotomy ...
The key diagnostic feature of AgP is vertical bone loss around teeth including the first molars and incisors. This tends to begin around puberty in otherwise healthy individuals. [36] There may be an appearance of "arc-shaped loss of alveolar bone extending from the distal surface of the second premolar to the mesial surface of the second molar ...
Permanent maxillary first molar notation. In the universal numbering system, one number is used to identify the tooth. The right permanent maxillary first molar is known as tooth "3", and the left permanent maxillary first molar is known as tooth "14". In the Palmer notation, a number and symbol are used to identify the tooth. The number ...
