Introduction:From the point of dental practice, the restoration of endodontically treated teeth has become an important aspect as it involves a range of treatment options of variable complexity. Restoring teeth with insufficient coronal tooth structure, it is always indicated to use the post to retain a core for definitive restoration. Fiber post has a modulus of elasticity in analogs to dentin structure, thus reducing the stress areas at the dowel dentin interface. However, the only material that can substantiate all these properties can be none other than dentin itself.Materials and Methodology:Three-dimensional (3D) models of the maxillary central incisor were developed incorporating all the nonlinearities. Continuum 3D elements were used in three dimensions. Maxillary central incisor was laser scanned, duplicated with the help of reverse engineering into STL format, and it was converted into 3D model for finite element analysis (FEA). For the model, fixed boundary conditions were applied at the outer bone, while 100 N static vertical occlusal loads were prescribed at 135° on the loading component of the simulated tooth. The stress distribution was evaluated using dentin and fiber post with prescribed materials, loading and boundary conditions in endontically treated teeth by 3D FEA.Results:The analysis for von Misses stress for dentin post showed that the stress in the dentin post at the cervical area was 127 MPa. The displacement in the dentin post was <0.025 mm. Von Misses stress for the fiber post at the cervical area was approximately 182 MPa and the displacement was <0.035 mm.Conclusion:The FEA results showed that the stress in the cervical area of the dentin was more for fiber post when compared to dentin post, and maximum displacement values were less for dentin post in comparison to fiber post.

“…It has been revealed that the PBS values of human EDPs were significantly higher than bovine EDPs. This study also aimed to evaluate each sterilization method's effect on the PBS of the dentin posts, since the biological dentin post materials must be sterilized before placing into the rooth canal (4). Gamma radiation has been used successfully to sterilize the allograft materials as well as medical devices and food marketing (17).…”

“…Experimental dentin posts (EDPs) need to be sterilized in a way that does not alter the structure of the material. Clinical studies on biological dentin posts generally used autoclaving (at 121°C) for sterilization (4,5). Gamma radiation can be an alternative sterilization method for dentin posts, which has been indicated with no significant effect on the teeth structure by related studies (13,14).…”

“…It has been revealed in recent studies that natural tooth fragments can be used as dentin posts with resilience comparable to that of the original tooth, extremely good adhesion to the dental structure and composite resin, and low cost (as dentin posts are made from donated extracted natural teeth) (1)(2)(3)(4)(5). Moreover, the use of dentin posts has reported successful outcomes in related clinical studies (4,5). In conservative dentistry, minimally structure removing is one of the main approaches in root canal preparation for post material (6).…”

The purpose of this preliminary study is to evaluate the push-out bond strength (PBS) of experimental dentin posts (EDPs) obtained from human and bovine teeth sterilized by autoclaving and gamma radiation. Eighty-four mandibulary premolars were obturated and divided into three post groups: the glass fiber group (Fb) human EDP group (Hm) and the bovine EDP group (Bv). Three subgroups (n=12) were obtained for each EDP groups according to the sterilization methods; no sterilization (Cnt), steam autoclaving (Aut), and gamma radiation (Rad) a total dose of 25 kGy. All posts were cemented to root canals using a dual cured resin cement (Panavia SA). After the micro slices (1mm in thickness) were obtained of each subgroup, PBS test was performed. Data were analyzed using two-way ANOVA and Tukey’s multiple comparison tests (α=.05). The post type and sterilization method was significantly effective on the PBS values according to the ANOVA (P<.001). No sterilization apllied EDP groups showed significantly higher PBS values than the sterilized groups (P<.001). Bv_Cnt (9.42 ±1.31) showed significantly lower PBS values than both Fb (12.36 ±1.54) and Hm_Cnt (11.06 ±1.38) groups (P<.001). Both steam autoclaving and gamma radiation affect the PBS values and fracture modes of EDPs negatively. The bovine EDPs are not as effective as human EDPs with regard to the PBS to the root dentin.

“…There are few studies in the literature regarding biological dentin posts. 17,25,[34][35][36] Correa-Feria et al 17 reported that this post treatment, defined as biological restoration by Trope, 37 is a successful alternative to reconstruction in endodontically treated teeth. A dentin post study by Belli et al 25 used a methodology similar to that of our study; however, in the present study, a complete ceramic crown was applied to the post-applied models, whereas the force was directed to the cervical region in the study by Belli et al 25 Therefore, stress accumulation was observed only in regions where the force was applied, while greater stress was observed in the stainless steel post.…”

Background. Several types of post have been developed for clinical use. A biological dentin post obtained from an extracted tooth eliminates the problems arising from material differences and reduces the fracture rate in teeth undergoing root canal treatment. This study used finite element analysis to compare a biological dentin post with posts made of two different materials. Methods. Three 3D models of the upper central incisor were created, and stainless-steel, glass fiber and biological dentin posts were applied to these models. The restoration of the models was completed by applying a composite as the core structure and a ceramic crown as the superstructure. Using finite element stress analysis in the restoration models, a 100-N force was applied in the vertical and horizontal directions and at a 45º angle, and the suitability of the biological dentin post was evaluated by comparing the data. Results. Under the applied forces, the greatest stress accumulation was seen in the models with the stainless steel post. Because the stainless steel post was more rigid, stress forces accumulated on the surface instead of being transmitted to the tooth tissue. In the models with the glass fiber and biological dentin posts, the post material responded to the stratification in tandem with the dental tissue and did not cause excessive stress accumulation on the tooth or post surfaces. Conclusion. The results showed that biological dentin posts prevent the accumulation of stresses that might cause fractures in teeth undergoing root canal treatment. In addition, the physical compatibility and biocompatibility of a biological dentin post with the tooth imply that it is a good alternative to the types of post currently used.
