Abstract：
The congenital absence of teeth is the most common dental anomaly affecting 2.2% to 10% of the population. It could be present in the form of anodontia, hypodontia, or oligodontia, excluding wisdom teeth. Oligodontia is most commonly associated with several syndromes like ectodermal dysplasia, Down syndrome, and Van der Woude syndrome that involve the mutation of the MSX-1 and PAX-1 genes. Few cases have been reported in the literature on how oligodontia affects primary dentition. In this case report, a total of 17 primary teeth were missing. This case report investigates whether the features of non-syndromic oligodontia are present in the primary dentition in a two-year-old boy.
