It is usually completely asymptomatic and is discovered on a routine radiographic examination or to evaluate the reason for an erupted tooth. Radiographically, this cyst usually presents a well-defined unilocular radiolucency attached to CEJ of an unerupted tooth which can cause displacement of adjacent tooth or resorption.</span></span><br> <span style="line-height:115%"><span style="line-height:115%">This article reports a large infected DC in a 10-year-old male patient related to first and second premolar maxillary teeth, which did not erupt or even change their positions. DC was treated successfully by decompression. After 2 years follow up, there was no evidence of recurrence. In conclusion, marsupialization of cyst with no orthodontic intervention or tooth extraction is a conservative, efficient protocol that stimulates bone healing and promotes the eruption of unerupted teeth even if they are deeply crowded.</span></span></span></span></p> Dentigerous Cyst,Tooth Unerupted,Case reports, 1 6 http://goums.ac.ir/jorjanijournal/browse.php?a_code=A-10-849-1&slc_lang=en&sid=1 Aliakbar Naghavialhosseini dr.naghavialhosseini@goums.ac.ir 10031947532846008318 0000000341223828 Yes Dental Research Center, Department of Orthodontics, Dental School, Golestan University of Medical Sciences, Gorgan, Iran Mina Pakkhesal m_pakkhesal@yahoo.com 10031947532846008319 000000021043836X No Dental Research Center, Department of Community Oral Health, Dental School, Golestan University of Medical Sciences, Gorgan, Iran Maryam Ghelichli goldis.ghelichli@gmail.com 10031947532846008320 0000000151253727 No Dental Research Center, Department of Oral and Maxillofacial Pathology, Dental School, Golestan University of Medical Sciences, Gorgan, Iran Amir Reza Ahmadinia ar.ahmadinia@gmail.com 10031947532846008321 0000000174286652 No Dental Research Center, Faculty of Dentistry, Department of Periodontics, Golestan University of Medical Sciences, Gorgan, Iran
