A panoramic examination of an 11-year-old boy presenting with a chief complaint of dental caries revealed delayed eruption of the maxillary right second molar and a radiolucency around the crown. In addition, cone-beam computed tomography revealed slight calcifications within a cystic lesion measuring 20 \u00d7 18 \u00d7 13 mm, and demonstrated root resorption of the first molar. Following root canal treatment of the first molar, the lesion was removed under general anesthesia. Histological findings of the resected lesion confirmed the diagnosis of a developing odontoma. This report highlights the importance of early detection of odontomas through radiographic examination.<\/jats:p>","DOI":"10.3390\/reports9030238","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T10:48:28Z","timestamp":1784717308000},"page":"238","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Developing Odontoma with Radiolucency in the Maxillary Right Second Molar"],"prefix":"10.3390","volume":"9","author":[{"given":"Tatsuya","family":"Akitomo","sequence":"first","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8305-667X","authenticated-orcid":false,"given":"Yuria","family":"Asao","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nanako","family":"Kataoka","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Pathobiology, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"},{"name":"Center of Oral Clinical Examination, Hiroshima University Hospital, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3141-8173","authenticated-orcid":false,"given":"Toshinori","family":"Ando","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Pathobiology, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6652-0007","authenticated-orcid":false,"given":"Mikihito","family":"Kajiya","sequence":"additional","affiliation":[{"name":"Center of Oral Clinical Examination, Hiroshima University Hospital, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryota","family":"Nomura","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, Graduate School of Biomedical and Health Sciences, Hiroshima University, Hiroshima 734-8553, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Alarc\u00f3n Apablaza, J., Mu\u00f1oz, G., Arriagada, C., Bucchi, C., Masuko, T.S., and Fuentes, R.
