Among them, calcific deposit or odontoma is commonly associated with primary dentition. Early diagnosis and treatment is the key to prevent complications. However, results of treatment may vary depending on the condition of unerupted tooth. Here we report two clinical cases of unerupted primary mandibular second molars with physical barriers such as compound odontoma and calcific deposit focusing on diagnostic means and the importance of early treatment of these lesions.<\/jats:p>","DOI":"10.17796\/1053-4628-42.2.12","type":"journal-article","created":{"date-parts":[[2017,10,31]],"date-time":"2017-10-31T18:05:21Z","timestamp":1509473121000},"page":"150-154","source":"Crossref","is-referenced-by-count":1,"title":["Decompression for Unerupted Primary Mandibular Second Molars Associated with Physical Barriers: Case Reports"],"prefix":"10.22514","volume":"42","author":[{"given":"Dae-Woo","family":"Lee","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae-Gon","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yeon-mi","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"26027","reference":[{"key":"p_1","volume-title":"Ed.
