J Sharif Med Dent Coll Jan ;4(02):84-8.

Objective: To determine the frequency of maxillary peg lateral incisors in a sample of Pakistani school children. Methodology: The cross-sectional epidemiological survey was done in 2014. The study was approved by the ethical committee of the institution. The sample consisted of 550 patients, of which 347 were females and 203 were males with the age range of 7-16 years. Data was collected by clinical intraoral examination of children for peg lateral incisors. The frequency of maxillary peg lateral incisors was calculated by quadrant and gender. The applied mathematical analysis was implemented with SPSS version 20. Qualitative data like gender and side of dentition was presented in the form of frequency and percentages. Data was stratified for gender. Post-stratification chi-square test was applied with a p-value <0.05 as significant. Results: The frequency of peg laterals in the sample was 1.8%. Females have higher incidence than males for peg laterals in maxillary arch (2% in females vs 1.4% in males). The incidence of bilateral peg laterals (1.1%) was higher in both female and male patients (66.7% and 33.3% respectively) than unilateral peg laterals (0.7%). Unilateral left sided peg was more common (0.5%). The significance level of gender and frequency of maxillary peg lateral incisor is 0.88, hence, insignificant. Conclusion: Maxillary peg lateral is a less common dental anomaly. One-sided peg laterals are domineering on the left side and in females. Comparatively bilateral peg is more frequent than unilateral one and occurs more commonly in females than males. Keywords: Congenitally missing. Lateral Incisors. Orthodontics. Peg lateral incisors
