This paper presents a distinctive case in which a primary molar with complete root development and furcation involvement\u2014usually an indication for conventional pulpectomy\u2014was instead treated with LSTR, a technique generally recommended in advanced root resorption. The case adds evidence on the potential indications and clinical versatility of this approach in pediatric dentistry. A pediatric patient with uncooperative behavior presented with discomfort in a primary molar. Clinical and radiographic examination revealed pulp necrosis, complete root formation, and a furcation lesion. Although pulpectomy was the conventional indication for such findings, LSTR was chosen as a conservative alternative. Treatment consisted of the placement of an antibiotic mixture in the pulp chamber to disinfect and sterilize the root canal system without mechanical instrumentation, with the objective of controlling infection and promoting tissue repair. At the 5\u2010year follow\u2010up, the tooth remained functional and symptom\u2010free, with radiographic evidence of healing and tissue regeneration, demonstrating favorable long\u2010term outcomes. This case shows that LSTR can provide favorable long\u2010term outcomes even in situations where pulpectomy would traditionally be indicated. It supports LSTR as a less invasive and effective option for preserving primary molars until their natural exfoliation.<\/jats:p>","DOI":"10.1155\/crid\/8629672","type":"journal-article","created":{"date-parts":[[2025,11,10]],"date-time":"2025-11-10T05:46:28Z","timestamp":1762753588000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["LSTR Technique With CTZ Antibiotic Paste in Primary Molar: 5\u2010Year Follow\u2010Up Case Report"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7346-6616","authenticated-orcid":false,"given":"Mar\u00eda","family":"del Carmen S\u00e1nchez Pumeda","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1940-7129","authenticated-orcid":false,"given":"Olga","family":"Henr\u00edquez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,11,9]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12903-021-01396-4"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.17796\/1053-4628-41.4.284"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016357.2015.1104721"},{"key":"e_1_2_12_4_2","first-page":"415","volume-title":"The Reference Manual of Pediatric Dentistry","author":"American Academy of Pediatric Dentistry","year":"2022"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1590\/S0103-64402006000400010"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.17796\/1053-4625-43.1.4"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/iej.12328"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/iep.12292"},{"key":"e_1_2_12_9_2","article-title":"Lesion Sterilization and Tissue Repair of Primary Molar to the Eruption of Its Permanent Successor: A Case Report","volume":"25","author":"Moreira C.
