@@ A supernumerary tooth occurs in addition to the normal scries of teeth and can be found in almost any region of the dental arch. It occurs with primary and permanent teeth, but it is more common with permanent teeth.1 It can be present in the maxilla or in the mandible and can be only single, multiple, unilateral, or bilateral.2 The reported prevalence of this abnormality varies from 1.5% to 35% in permanent dentition compared with 0.3% to 0.6% in deciduous dentition. Supernumerary teeth are more frequent in males than in females at a proportion of 2:1.3 The most frequent locations for supernumerary teeth are the midline of the maxilla, the palatal area of the upper incisors, the lower premolar area, and the distal of the upper and lower third molars.4 An accessory tooth rarely grows in areas other than the dental arches, but similar cases have been reported, such as an extra tooth in the nasal cavity, inferior nasal concha, ge-nyantrum, ethmoid sinus, and skull.5'9 However, a case of a supernumerary tooth in the horizontal plate of palatine bone has not been reported. This report introduces 2 cases of a supernumerary tooth in the horizontal plate of palatine bone.
