Their irregular anatomy complicates effective debridement and increases the risk of irrigant extrusion during conventional irrigation procedures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation:<\/jats:title>\n                    <jats:p>A 33\u2010year\u2010old female with a history of asthma presented with a chief complaint related to maxillary lateral incisor #7. Clinical examination revealed normal probing depths, absence of tenderness to percussion and palpation, no mobility, and no response to cold testing. Periapical radiography demonstrated two well\u2010defined, balloon\u2010shaped radiolucencies in the coronal third of the canal. CBCT revealed an extensive resorptive defect with perforation of the buccal canal wall, round internal morphology, and thinning of dentinal walls\u2014features most consistent with ECR, although a combined IRR\/ECR process could not be excluded. Because of the patient\u2032s sensitivity to the odor of sodium hypochlorite, a sealed irrigation system was employed. A dual\u2010needle setup was used in which 5.25% NaOCl was delivered apically through a 27\u2010gauge needle while simultaneous coronal suction via a 22\u2010gauge needle created controlled negative pressure within a sealed chamber. This configuration allowed continuous irrigant exchange and effective debridement while minimizing extrusion risk and patient discomfort. The canal was obturated using an MTA\u2010based sealer. At the 17\u2010month follow\u2010up, the tooth remained functional and asymptomatic, with radiographs showing periapical stability and no evidence of recurrent or progressive resorption.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case demonstrates that a sealed, negative\u2010pressure irrigation technique can provide a safe and effective method for managing complex resorptive defects\u2014particularly when patient\u2010related limitations and diagnostic ambiguity make traditional irrigation approaches insufficient.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/crid\/2066169","type":"journal-article","created":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T06:56:55Z","timestamp":1770965815000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Sealed Irrigation Approach for Root Resorption: Case Report With Review of Irrigation Strategies"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9170-653X","authenticated-orcid":false,"given":"Mohsen","family":"Aminsobhani","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7233-1339","authenticated-orcid":false,"given":"Nasim","family":"Hashemi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5875-9912","authenticated-orcid":false,"given":"Fatemeh","family":"Malekpour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,2,12]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1111\/iej.13916"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/iej.13715"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.4103\/endo.endo_186_21"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1308\/205016816819304222"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/iej.13800"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/iej.13739"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1590\/1807-3107bor-2021.vol35.0123"},{"key":"e_1_2_9_8_2","article-title":"Comparison of the Cleaning Efficacy of Self-Adjusting File and Rotary Systems in the Apical Third of Oval-Shaped Canals","volume":"28","author":"Versiani M.","year":"2025","journal-title":"Compartir"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm13237113"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12903-022-02626-z"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-021-04123-z"},{"key":"e_1_2_9_12_2","doi-asserted-by":"publisher","DOI":"10.1177\/00368504221109217"},{"key":"e_1_2_9_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD008003.pub3"},{"key":"e_1_2_9_14_2","doi-asserted-by":"publisher","DOI":"10.1590\/0103-6440201801750"},{"key":"e_1_2_9_15_2","volume-title":"Apical Negative Pressure: Safety, Efficacy and Efficiency.
