Materials and Methods: Twenty intact human upper jaw central incisors extracted due to periodontal diseases were selected for this trial. Endodontic treatment was performed according to ISO recommendations. A total of 4 mm of guttapercha was left in the apical region. Canals were prepared for post insertion. Teeth were randomly allocated into the two following groups depending on the core restorative material (n = 10): I\u2014cores build up with light cured composite; II\u2014cores build up with dual cured composite resin. GFPs were inserted and cores were rebuilt with different composite resins. Longitudinal cuts were made across the axis of the teeth and examined under a scanning electron microscope (SEM). Statistical analysis was accomplished using Mann\u2013Whitney U and Spearman tests (p &lt; 0.05). Results: In the group where the number and size of pores at the interface of GFPs were analyzed, pores were found only in the specimens restored with the light-cured \u201cbulk-filled\u201d composite. In the group where the number and size of pores in the core material were analyzed, pores were found in specimens restored with both the light-cured \u201cbulk-filled\u201d composite and dual-cured resin composite. However, the dual-cured resin composite yielded better results in terms of core integration. Conclusions: There is no statistically significant correlation between the homogeneities of different composite materials and their adhesion to GFP.<\/jats:p>","DOI":"10.3390\/dj13070290","type":"journal-article","created":{"date-parts":[[2025,6,27]],"date-time":"2025-06-27T05:29:58Z","timestamp":1751002198000},"page":"290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Correlation Between Homogeneity of Different Composite Resins and Their Adhesion to Glass Fiber Posts: In Vitro Assessment"],"prefix":"10.3390","volume":"13","author":[{"given":"\u017divil\u0117","family":"Oleinikait\u0117","sequence":"first","affiliation":[{"name":"Faculty of Odontology, Medical Academy, Lithuanian University of Health Sciences, Eiveniu 2, LT-50161 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gediminas","family":"Skirbutis","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Odontology, Lithuanian University of Health Sciences, Sukileliu Ave. 51, LT-50106 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Greta","family":"Rutkauskait\u0117","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Faculty of Odontology, Lithuanian University of Health Sciences, Sukileliu Ave. 51, LT-50106 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,27]]},"reference":[{"key":"ref_1","first-page":"CD005296","article-title":"Single versus multiple visits for endodontic treatment of permanent teeth","volume":"2023","author":"Mergoni","year":"2022","journal-title":"Cochrane Database Syst.
