Post\u2010operative periapical radiographs confirmed satisfactory canal filling in all cases. Follow\u2010up evaluation with periapical radiographs and cone\u2010beam computed tomography at 7\u201324\u2009months revealed partial intraradicular sealer reduction in all four cases. Two cases showed radiographic findings compatible with periapical healing and remained asymptomatic; two exhibited persistent or recurrent periapical pathology despite comparable radiographic sealer reduction. Outcome assessment was based on qualitative clinical and radiographic criteria; no quantitative volumetric or scoring\u2010based assessment was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key Learning Points<\/jats:title>\n                    <jats:p>(1) Radiographically detectable intraradicular reduction of a CSBS (AH Plus Bioceramic) can occur under routine clinical conditions following nonsurgical root canal retreatment. (2) This radiographic finding is not consistently associated with clinical outcome, suggesting uncertain prognostic significance. (3) Systematic long\u2010term investigations using standardized CBCT\u2010based volumetric analysis are required to determine whether intraradicular sealer reduction represents a biologically neutral remodelling process or a potential contributor to late treatment failure.<\/jats:p>\n
