**1. Introduction**

Cleft lip and/or palate (CLP) is a birth defect with heterogeneous clinical presentations [1]. Prevalence and cleft-types differ by gender, ethnic groups and geographic locations [2]. It has been widely reported that dental anomalies (delayed dental development and eruption, hypodontia, supernumeraries, hypoplasia and abnormalities in tooth size and shape) in CLP are commonly associated with the presence of the cleft [3].
