Supernumerary teeth are commonly affected by dentin dysplasia, a condition manifested when the number of teeth exceeds that of normal teeth. Supernumerary teeth are usually found in maxillary anterior areas and in maxillary molar areas. In other instances, supernumerary teeth are located in mandibular molar areas and mandibular premolar areas. In this report, two cases possessed five incisors located in the mandibular anterior region.
