Agenesis and Malformation of Maxillary Lateral Incisors in Orthodontic Patients. A Study

Abstract

Objective:  The purpose of this study was to deter-mine the prevalence of agenesis and malformation of maxillary lateral incisors in orthodontic patients.

Study design:  Cross sectional study.

Place and Duration of Study:  Department of Ortho-dontics, Faculty of dentistry, the University of Lahore, Pakistan; from January 2007 to march 2010.

Patients and Methods:  The data (history sheets, dental casts and panoramic radiographs) of 230 pati-ents (36.5% males, 63.5% females; mean age: 16.4 years) were randomly selected from orthodontic pati-ent's record. Congenital absence, size and shape of maxillary lateral incisors was noted. Patients with cleft lip and palate, ectodermal dysplasia or having any syndrome were excluded from the study.

Results:  The prevalence of small size lateral incisors was 5.6%. The prevalence of peg lateral was 1.3% and agenesis of maxillary lateral incisors was found in 2.17% of the patients.

Conclusion:  The prevalence of small maxillary lateral incisors is high as compared to other lateral incisor anomalies.

Key words:  Prevalence, maxillary lateral incisors, malformation.
