A search in dental literature reveals the occurrence of monoradicular molars in primary dentition; especially the monoradicular maxillary primary second molar is extremely rare, returning only five case reports. The present case of a 5\u2010year\u2010and\u20107\u2010month\u2010old girl presented with experience of severe pain in her upper left back area. After taking the medical and dental histories and conducting a clinical and radiographic examination, the examinations showed a healthy child, carious teeth, a localised abscess and a rare root morphology (monoradicular maxillary primary second molar), which has never been previously reported in the Saudi population. The treatment was performed using quadrant dentistry, which involved a pulpotomy and a stainless steel crown, extraction and a reverse band and loop, whilst keeping the child under regular follow\u2010up. The aim of this report is to assist dental practitioners, particularly dentists, in recognising this root anomaly that is a rare monoradicular maxillary left second molar so as to minimise the associated complications. In addition, this paper summarises similar cases in the dental literature. Achieving a high level of practical dental skills and accurate dental diagnoses promotes the standard of dental treatment, in turn leading to successful endodontic results.<\/jats:p>","DOI":"10.1155\/crid\/1034638","type":"journal-article","created":{"date-parts":[[2026,5,16]],"date-time":"2026-05-16T05:39:02Z","timestamp":1778909942000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Monoradicular Primary Maxillary Left Second Molar: A Rare Root Morphology and Review of the Literature"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6709-2964","authenticated-orcid":false,"given":"Basim","family":"Almulhim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,15]]},"reference":[{"key":"e_1_2_14_1_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0043-1772566"},{"key":"e_1_2_14_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00276-020-02633-1"},{"key":"e_1_2_14_3_2","doi-asserted-by":"publisher","DOI":"10.1242\/dev.137216"},{"key":"e_1_2_14_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s40368-025-01011-y"},{"key":"e_1_2_14_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2013-200034"},{"key":"e_1_2_14_6_2","first-page":"41","article-title":"Various Root Abnormalities: Report of Three Cases","volume":"74","author":"Arslan A.","year":"2008","journal-title":"New York State Dental Journal"},{"key":"e_1_2_14_7_2","doi-asserted-by":"publisher","DOI":"10.21276\/\/ujds.2022.8.4.17"},{"key":"e_1_2_14_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/ajpa.1330380305"},{"key":"e_1_2_14_9_2","first-page":"367","article-title":"Single-Rooted Molars in the Primary and Permanent Dentition in Two Siblings: Case Report","volume":"13","author":"Holan G.","year":"1991","journal-title":"Pediatric Dentistry"},{"key":"e_1_2_14_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/s1079-2104(96)80306-4"},{"key":"e_1_2_14_11_2","doi-asserted-by":"publisher","DOI":"10.4103\/0970-7212.351845"},{"key":"e_1_2_14_12_2","doi-asserted-by":"publisher","DOI":"10.5368\/aedj.2010.2.2.36-39.pdf"},{"key":"e_1_2_14_13_2","doi-asserted-by":"publisher","DOI":"10.7860\/jcdr\/2018\/35023.11615"},{"key":"e_1_2_14_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(64)90376-7"},{"key":"e_1_2_14_15_2","doi-asserted-by":"publisher","DOI":"10.4103\/0970-9290.99050"},{"key":"e_1_2_14_16_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2591.2002.00461.x"},{"key":"e_1_2_14_17_2","doi-asserted-by":"publisher","DOI":"10.4103\/0970-4388.66755"},{"key":"e_1_2_14_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2005.10.057"},{"key":"e_1_2_14_19_2","first-page":"355","article-title":"Primary Mandibular First Molar With Single Root and Single Canal: A Case Report of a Rare Morphology","volume":"11","author":"Bahrololoomi Z.","year":"2014","journal-title":"Journal of Dentistry"}],"container-title":["Case Reports in Dentistry"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crid\/1034638","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crid\/1034638","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crid\/1034638","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,20]],"date-time":"2026-06-20T20:45:03Z","timestamp":1781988303000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crid\/1034638"}},"subtitle":[],"editor":[{"given":"Hannah","family":"Wesley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":19,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1155\/crid\/1034638"],"URL":"https:\/\/doi.org\/10.1155\/crid\/1034638","archive":["Portico"],"relation":{},"ISSN":["2090-6447","2090-6455"],"issn-type":[{"value":"2090-6447","type":"print"},{"value":"2090-6455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2025-12-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-05-08","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-05-15","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"1034638"}}
