Abstract

Aim and background: Being in the most esthetic region of the mouth, congenitally missing maxillary lateral incisors (CMMLI) tag along with them a unique set of problems. The few global studies done report great racial variation. There is no Sri Lankan study, and even regional data are sparse. Materials and methods: A cross-sectional study was conducted on 2044 schoolchildren aged 10 years from 20 schools selected randomly in Colombo, Sri Lanka. The screening was done at these schools by a single dentist. Necessary referrals were made to the institute of oral health (IOH) in Maharagama, Sri Lanka. The results were analyzed using Statistical Package for the Social Sciences (SPSS) 21 and presented using descriptive statistical measures. Results: The overall prevalence of CMMLI was 1.177%, of which 62.5% were in females and 37.5% in males. About 70.8% had a bilateral distribution, whereas 29.2% were unilateral, mostly on the right side. In unilateral cases, the existing one was mainly diminutive. Though it is too early for planning, most cases would tentatively require space closure. Conclusion: The prevalence of this study was following globally quoted figures of 1–2%. Further research with larger samples is needed for conclusions.
