Objective: The study was conducted to investigate the prevalence of maxillary lateral incisor agenesis and variation in its size in an orthodontic population and to relate its frequency with different skeletal malocclusions and gender.
Material and Methods: Sample consisted of 361 patients, of which 193 were female and 168 were male with the age range12-35 years. Panoramic radiographs were used to diagnose the agenesis of maxillary lateral incisor (LI) and dental casts for presence of peg laterals, <ANB was measured from lateral cephalograms.
Results: Thirty four (9.42%) patients were found to have agenesis of maxillary lateral incisor, of which 44.12% were female and 55.88% were male. Patient having peg laterals were 5.26%. Among the different skeletal classifications, patients with skeletal class I malocclusion had bilaterally missing LI (52.94%), patients with class II malocclusion had equal frequency of bilateral and left unilateral missing LI (38.46%) and skeletal class III patients had a greater frequency of right unilateral missing LI (75.00%). The highest incidence was of presence of bilateral peg laterals (52.63%) in both female and male patients (50.00% and 54.55% respectively).
Conclusions: Bilateral agenesis of LI with skeletal class I malocclusion is more common and occurs predominantly among male population.
