The strict meaning of the term retarded eruption is that tooth eruption is delayed compared to its developmental stage. The etiological factors for it may be local, systemic or genetic. Its pathogenic mechanism is unknown in most cases. In cases of generalized retarded eruption without any clear reason, the general growth and development seems normal in all aspects and the teeth usually keep the normal eruption sequence. Usually the primary teeth may often be extracted hoping to provoke the eruption of the retarded teeth, only to be proved a failure. Consequently, the patient will be without teeth for many years, with loss of esthetics, loss of occlusal height and resorption of alveolar process. The primary goal in the treatment may therefore be to keep and maintain the primary teeth in good condition until they are naturally shed. This observation was done on 10 year 1 month old patient who were diagnosed as idiopathic retarded eruption through both radiographic and systemic examination and follow-up observation was done for 11 month.
