Each group was further subdivided into two sub-groups depending on the test used: fracture resistance test and push-out bond strength test. The all specimens were mounted in acrylic resin blocks and tested using a universal testing machine. The fracture and failure mode were determined by a stereomicroscope inspection of all the specimens. Data were analyzed by one-way analysis of variance (ANOVA) and the Bonferroni\n post hoc<\/jats:italic>\n test (\n P<\/jats:italic>\n < 0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n There was a statistically significant difference between fracture resistance and push-out bond strength values for the experimental groups (\n P<\/jats:italic>\n < 0.05). The most significant fracture resistance value was in Group II and core\/post fracture (restorable fracture) was the most obvious fracture in the three groups with the highest percentage in Group I. The most significant push-out bond strength value was in Group I and adhesive failure between dentin and luting cement\/post was the most common type in the groups.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n \n The fracture resistance and push-out bond strength were affected by the type of post (\n P<\/jats:italic>\n = 0.000). Prefabricated glass fiber posts showed the highest fracture resistance in this study. However, Tetric N Ceram composite posts had the most restorable fracture. Tetric N Ceram composite posts had the highest bond strength with adhesive failure mode.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/ijdr.ijdr_202_23","type":"journal-article","created":{"date-parts":[[2024,7,8]],"date-time":"2024-07-08T07:00:13Z","timestamp":1720422013000},"page":"221-226","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Fracture Resistance and Push-Out Bond Strength of Three Post Types in the Restoration of Anterior Primary Teeth - A In Vitro study"],"prefix":"10.4103","volume":"35","author":[{"given":"Asmaa E.","family":"Eltobgy","sequence":"first","affiliation":[{"name":"Department of Pedodontics and Oral Health, Faculty of Dental Medicine, Al-Azhar University for Girls, Nasr City, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magda","family":"Elmalt","sequence":"additional","affiliation":[{"name":"Department of Pedodontics and Oral Health, Faculty of Dental Medicine, Al-Azhar University for Girls, Nasr City, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alaa","family":"Eldehna","sequence":"additional","affiliation":[{"name":"Department of Pedodontics and Oral Health, Faculty of Dental Medicine, Al-Azhar University for Girls, Nasr City, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2024,7,4]]},"reference":[{"key":"R1-20241009","doi-asserted-by":"crossref","first-page":"282","DOI":"10.1111\/j.1365-263X.2005.00645.x","article-title":"Restoration of severely decayed primary incisors using indirect composite resin restoration technique","volume":"15","author":"Motisuki","year":"2005","journal-title":"Int J Paediatr Dent"},{"key":"R2-20241009","doi-asserted-by":"crossref","first-page":"29","DOI":"10.4103\/0976-9668.107257","article-title":"Early childhood caries update:A review of causes, diagnoses, and treatments","volume":"4","author":"\u00c7olak","year":"2013","journal-title":"J Nat Sci Biol Med"},{"key":"R3-20241009","first-page":"282","article-title":"The influence of restorative material on the survival rate of restorations in primary molars","volume":"16","author":"Papathanasiou","year":"1994","journal-title":"Pediatr Dent"},{"key":"R4-20241009","doi-asserted-by":"crossref","first-page":"705","DOI":"10.5005\/jp-journals-10005-2034","article-title":"Posts in primary teeth\u2013past to present:A review of literature","volume":"14","author":"Martin","year":"2021","journal-title":"Int J Clin Pediatr Dent"},{"key":"R5-20241009","doi-asserted-by":"crossref","first-page":"99","DOI":"10.17796\/jcpd.30.2.360k2j4452773418","article-title":"An esthetic point of view in very young children","volume":"30","author":"Kapur","year":"2005","journal-title":"J Clin Pediatr Dent"},{"key":"R6-20241009","first-page":"17","article-title":"Comparison of the retentive strength of 3 different posts in restoring badly broken primary maxillary incisors","volume":"77","author":"Gujjar","year":"2010","journal-title":"J Dent Child"},{"key":"R7-20241009","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1111\/j.1365-263X.2006.00680.x","article-title":"Clinical performance of resin-bonded composite strip crowns in primary incisors:A retrospective study","volume":"16","author":"Ram","year":"2006","journal-title":"Int J Paediatr Dent"},{"key":"R8-20241009","doi-asserted-by":"crossref","first-page":"553","DOI":"10.14219\/jada.archive.1990.0071","article-title":"Composite resin short-post technique for primary anterior teeth","volume":"120","author":"Judd","year":"1990","journal-title":"J Am Dent Assoc"},{"key":"R9-20241009","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1016\/S0300-5712(98)00066-9","article-title":"Stiffness, elastic limit, and strength of newer types of endodontic posts","volume":"27","author":"Asmussen","year":"1999","journal-title":"J Dent"},{"key":"R10-20241009","doi-asserted-by":"crossref","first-page":"159","DOI":"10.5005\/jp-journals-10005-1158","article-title":"Glassfiber post:An alternative for restoring grossly decayed primary incisors","volume":"5","author":"Mehra","year":"2012","journal-title":"Int J Clin Pediatr Dent"},{"key":"R11-20241009","doi-asserted-by":"crossref","first-page":"682","DOI":"10.1046\/j.1365-2842.2002.00908.x","article-title":"Mechanical properties of two restorative reinforced glass\u2013ionomer cements","volume":"29","author":"Yap","year":"2002","journal-title":"J Oral Rehabil"},{"key":"R12-20241009","first-page":"55","article-title":"Esthetic restoration of primary incisors","volume":"12","author":"Carranza","year":"1999","journal-title":"American journal of dentistry"},{"key":"R13-20241009","first-page":"36","article-title":"Conventional glass ionomers as posterior restorations.
