Multidisciplinary Aesthetic Dental Treatment; Peg lateral with Congenitally Maxillary lateral Incisors

Abstract

Maxillary lateral incisors vary in form more than any other tooth in the mouth except the third molars. If the variation is too great, it is considered a developmental anomaly. Developmental alterations which are most commonly associated with maxillary lateral incisors either unilaterally or bilaterally are microdontia, hypodontia, dens invaginatus and dens evaginatus (talon cusp). Microdontia is a condition where the teeth are smaller than the normal size, which may involve all the teeth or be limited to a single tooth or a group of teeth. However, involvement of single tooth is a rather common condition, especially involving maxillary lateral incisor. Microdontia of maxillary lateral incisor is called as "peg lateral", that exhibit converging mesial and distal surfaces of crown forming a cone like shape. The root on such a tooth is usually shorter than usual. In this article, a case is reported of a young patient with one congenitally missing and one peg shaped lateral incisor. The patient was treated with a combination of orthodontics, periodontal surgery and aesthetic restorative dentistry interventions.

Associations between Bolton ratio and overjet deviations in a Finnish adult population

“…The results of this study suggest that overjet deviations partly result from variations of teeth width, in particular maxillary anterior teeth widths. The most common sporadic teeth size disharmony is peg-shaped lateral incisor [25]. In the present study, a larger variation of the maxillary right lateral incisor mesiodistal width was found, matching the existence of peg-shaped lateral incisors.…”
