A peg lateral is defined as "an undersized, tapered, maxillary lateral incisor" that may be associated with other dental anomalies such as canine transposition and over retained deciduous teeth.
The orthodontic alignment is done in such a way that 2mm space is left mesial and distal to the peg laterals to allow esthetic build up.
The objective of this study was to analyze the prevalence of peg lateral incisors with of maxillary buccally displaced canines (BDC).
impaction is a infraosseous position of the tooth after the expected time of eruption, whereas displacement is a anomalous infraosseous position before the expected time of eruption.4 The term "Peg lateral" refers to an morphological disturbance in which lateral incisors appear abnormally small in size compared to their usual more rectangular shape.5 Anomalies in lateral incisor size may lead to disturbances in upper and lower arch length and occlusion and may also cause aesthetic and psychological issues.

Tooth impaction can be defined as the infraosseous position of the tooth after the expected time of eruption, whereas the anomalous infraosseous position of the canine before the expected time of eruption can be defined as a displacement.1 The term "Peg lateral" refers to an anomaly affecting the upper lateral incisors which causes these teeth to be abnormally small in size or even 'pointy' compared to their usual more rectangular shape.2
The significance of association between peg lateral incisors with of PDC was analyzed with the chi-square test.

The purpose of this study was to determine the prevalence of peg laterals and small lateral incisors in orthodontic patients, visiting the orthodontic department, faculty of dentistry, the university of Lahore.
They may be linked with missing or peg lateral incisors, an absence of crowding, and late developing dentitions.6,7
Of consideration is the association of this case with root dilaceration of the impacted second molar and the presence of maxillary peg laterals. Since the impacted second molar had the anomaly of dilaceration, its chance for eruption was minimal.
Results of this study are in agreement with previous studies conducted.10,43-44 Transposition may occur with other anomalies, such as peg laterals and retention of deciduous teeth.41
