The designs tested were the TT, conservative trapezoidal (CT), ultraconservative circular (UC), and two conservative single accesses (TC). Materials and Methods: A mandibular right first molar typodont tooth was prepared for a full coverage zirconia crown. The preparation was scanned, and a total of 56 monolithic zirconia crowns were milled. Resin dies were printed for each restoration. Crowns were cemented with dual curing resin cement to the printed dies. The specimens were artificially aged with 10,000 thermal cycles between 5 degrees C and 55 degrees C with a dwell time of 30 s and were loaded to failure using a universal testing machine. Furthermore, scanning electron microscope (SEM) images were taken to evaluate the fracture patterns of the specimens. The fracture load was analyzed using the Shapiro-Wilks normality test, followed by a one-way ANOVA with a post hoc Tukey test. Results: The fracture resistance of mandibular molar zirconia crowns significantly varied according to the endodontic access cavity design. Crowns with UC access had the highest fracture resistance (2722 +/- 113 N, p < 0.001), followed by the CT (2469 +/- 126 N) and the TT access (1915 +/- 71 N). The two-conservative single access design had the lowest value (1064 + 129 N). Conclusions: All endodontic access designs for mandibular molar zirconia crowns appeared to withstand the average occlusal forces. Crowns with UC access demonstrated the highest fracture resistance among different endodontic access designs. Two conservative single accesses in the same crowns significantly diminished the fracture resistance. true 2025 true true true false true false NONE 2026-07-21 false 2 0 2 0 2 2 2 2 2 2 2 0 0 0 2 0 2 0 2 0 0 1 1 Folyóiratcikk Journal Article 24 2 Könyvrészlet Chapter in Book 25 0 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2026 0 2 0 2 0 D1 false false false false 2026-01-26T12:28:52.152+0000 Fogpótlástani Klinika (SE / FOK) 1 8 1 6 0 true Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 128299299 /api/authorship/128299299 1 0.16666667 true false false Abuhammoud Salahaldeen true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 128299300 /api/authorship/128299300 2 0.16666667 false false false Jurado Carlos A. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 128299301 /api/authorship/128299301 3 0.16666667 false false false Rojas-Rueda Silvia true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 128299302 /api/authorship/128299302 4 0.16666667 false false false Garcia-Contreras Rene true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 128299303 /api/authorship/128299303 5 0.167 false false false Author 10059531 /api/author/10059531 Végh Dániel true 10059531 true Vegh Daniel true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 128299304 /api/authorship/128299304 6 0.16666667 false true true Lee Damian J. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 30068989 /api/publicationidentifier/30068989 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true 10.1111/jopr.70047 https://doi.org/10.1111/jopr.70047 false true PublicationIdentifier 30068990 /api/publicationidentifier/30068990 PlainSource 1 /api/publicationsource/1 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001597137800001 https://www.webofscience.com/wos/woscc/full-record/001597137800001 false true PublicationIdentifier 30068993 /api/publicationidentifier/30068993 PlainSource 3 /api/publicationsource/3 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true 105019193554 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105019193554 false true PublicationIdentifier 30068991 /api/publicationidentifier/30068991 PlainSource 17 /api/publicationsource/17 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true PubMed PubMed http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=@@@&dopt=Abstract true true 17 true 41108718 http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=41108718&dopt=Abstract false true Keyword 13617 /api/keyword/13617 true 13617 true Keyword 18622 /api/keyword/18622 true 18622 true Keyword 1202711 /api/keyword/1202711 true 1202711 true Keyword 1365512 /api/keyword/1365512 true 1365512 true Keyword 1606704 /api/keyword/1606704 true true Keyword 1629994 /api/keyword/1629994 true true Keyword 3262035 /api/keyword/3262035 true true Keyword 3924960 /api/keyword/3924960 true true SjrRating 11734608 /api/sjrrating/11734608 11 0.1 journal RatingType 10002 /api/ratingtype/10002 sjr true true ClassificationExternal 3501 /api/classificationexternal/3501 true 3501 true D1 FROM_LAST_YEAR true true /api/publication/36403500 <div class="JournalArticle Publication long-list"> <div class="authors"> <img title="Forrásközlemény" style="float: left" src="/frontend/resources/grid/publication-core-icon.png"> <img title="Idézőközlemény" style="float: left" src="/frontend/resources/grid/publication-citation-icon.png"> <div class="autype autype0"> <span class="author-name" >Abuhammoud Salahaldeen </span> ;&nbsp;&nbsp;&nbsp;
