A Sealed Irrigation Approach for Root Resorption: Case Report With Review of Irrigation Strategies
Mohsen Aminsobhani, Nasim Hashemi, Fatemeh Malekpour

TL;DR
A sealed irrigation technique was used to safely treat a complex root resorption case in a patient with sensitivity to traditional irrigants.
Contribution
A novel sealed, negative-pressure irrigation method was applied to manage resorptive defects with diagnostic uncertainty and patient-specific limitations.
Findings
The sealed irrigation system minimized irrigant extrusion and patient discomfort during treatment.
The treated tooth remained asymptomatic and stable for 17 months post-procedure.
The technique proved effective for managing complex resorptive defects with ambiguous diagnosis.
Abstract
Root resorptive defects present significant diagnostic and clinical challenges, particularly when differentiating internal root resorption (IRR) from external cervical resorption (ECR). Their irregular anatomy complicates effective debridement and increases the risk of irrigant extrusion during conventional irrigation procedures. A 33‐year‐old 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‐defined, balloon‐shaped 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—features most consistent with…
