The permanent maxillary central incisor is the widest tooth mesiodistally in comparison to any other anterior tooth. It is larger than the neighboring lateral incisor and is usually not as convex on its labial surface. As a result, the central incisor appears to be more rectangular or square in shape.
It is most commonly seen in school children. Dental subluxation is one of the most common traumatic injuries in primary dentition. Maxillary central incisors are the most commonly affected teeth. [10] [11] Some studies have proposed that the resilience nature of periodontium favours dislocation than fracture of the tooth itself. [12]
The duration of delay is around 0.2 to 0.9 years, with an average of 0.56 years when all types of clefts were accounted for. The lateral incisor on the cleft side was typically the most delayed. The type of cleft and the severity of the condition did not affect the duration of tooth eruption.
maxillary lateral incisor (upper jaw, beside the maxillary central incisor) mandibular central incisor (lower jaw, closest to the center of the lips) mandibular lateral incisor (lower jaw, beside the mandibular central incisor) Children with a full set of deciduous teeth (primary teeth) also have eight incisors, named the same way as in ...
Division 1 – the upper central incisors are proclined or of average inclination and there is an increase in overjet; Division 2 – The upper central incisors are retroclined. The overjet is usually minimal or may be increased. Class III: The lower incisor edges lie anterior to the cingulum plateau of the upper incisors.
The upper and lower central incisors are shed at age six to seven years. The upper and lower lateral incisors are shed at seven to eight years. The upper canines are shed at ten to twelve years. The lower canines are shed at nine to twelve years. The upper and lower first molars are shed at nine to eleven years. The upper and lower second ...
Microdontia is a condition in which one or more teeth appear smaller than normal. In the generalized form, all teeth are involved. In the localized form, only a few teeth are involved. The most common teeth affected are the upper lateral incisors and third molars.
