Forty single-rooted mandibular premolars were instrumented using the Reciproc R40 system and randomly assigned to four groups (n\u2009=\u200910 teeth each): (1) cold lateral compaction with AH Plus, (2) warm vertical compaction with AH Plus, (3) hydraulic single-cone obturation with gutta-percha and Bioserra sealer, and (4) sealer-only technique using the Bioserra bioceramic sealer. After storage at 37\u00b0C and 100% humidity for one week, 1-mm slices were prepared from the coronal, middle, and apical thirds and subjected to push-out testing. Data were analyzed using ANOVA and Tukey\u2019s test (p\u2009&lt;\u20090.05). Significant differences in push-out bond strength were observed among the obturation approaches using different sealer materials (p\u2009&lt;\u20090.05). Bioceramic sealers exhibited higher bond strengths than epoxy resin\u2013based sealers, particularly in the middle and apical thirds. Hydraulic single-cone and bioceramic sealer-only approaches outperformed conventional techniques (p\u2009&lt;\u20090.001), whereas no significant difference was observed between cold lateral and warm vertical compaction techniques. Obturation approaches employing bioceramic sealers demonstrated superior bonding in diabetic dentin, suggesting potential advantages over conventional methods in the context of diabetic dentin.<\/jats:p>","DOI":"10.1371\/journal.pone.0353975","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T17:36:53Z","timestamp":1784309813000},"page":"e0353975","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative
