Impaction of the tooth in primary dentition is very less common than the permanent dentition. Impaction of teeth in primary dentition may create various problems in occlusion and also in developing dentition. Clinical and radiographic evaluation of such cases may benefit the patient as well as the clinician. Among primary tooth impaction cases, second primary molars are not frequently reported along with late formation of its succedaneous tooth. Nevertheless, the purpose of this report was to describe a case of a rare entity of reverse dentition caused by the impaction of the mandibular primary second molar associated with delayed formation of the second premolar.
