“…In the present study, 50 high-resolution CBCT scans were assessed in patients with a diagnosis of tooth fracture. The results showed that the type of fracture is not related to the type of retention used, which coincides with the results reported by Tsai et al ( 24 ) where the presence of a post was not closely related to the presence of horizontal or vertical root fractures in posterior teeth ( 25 ). These results contrast with those reported by Maddalone et al ( 21 ) in a prevalence study showing an increased risk of vertical root fracture (VRF) in teeth restored with a post; these authors found a statistically significant difference in relation to teeth without a post.…”

Background Root fractures are a diagnostic challenge for dentists in endodontic treatment. This study aimed to determine the relationship between the characteristics of tooth fractures and the presence of root canal posts in endodontically treated teeth using high-resolution cone beam computed tomography (CBCT). Material and Methods Fifty high-resolution CBCT scans of endodontically treated teeth with a diagnosis of fracture were obtained, of which 30 were from women and 20 were from men. These scans were acquired with three Veraviewepocs 3D units and one 3D Accuitomo 170 unit, with a 40 × 40-mm field of view and 125 μm voxel size. The variables assessed included the type of fracture, extent of fracture, type of retention, post length, cause of endodontic failure, location of the lesion, and time required to detect the fracture (difficulty score). For data analysis, the chi-squared test, Student’s t-test, and multiple linear regression (α <0.05) were used. Results No association was found between the type of fracture and type of retention or between the type of fracture and its extent ( P >0.05). On the other hand, the type of fracture significantly influenced the time required for its detection. Additionally, the most difficult plane for detecting the fracture and the difficulty score were associated, with statistically significant results. Conclusions The type of fracture in endodontically treated teeth was not associated with the type of post used for restoration. All of the CBCT systems used to detect tooth fracture showed the same efficiency. Key words: Cone-Beam CT, Tooth Fracture, Root Canal Post.

Background: Root fractures are a diagnostic challenge for dentists because their signs and symptoms are not present in all cases, and they are difficult to differentiate from endodontic treatment failures, the purpose of the present study was to determine the relationship between the characteristics of tooth fractures and the presence of root canal posts in endodontically treated teeth using high-resolution cone beam computed tomography (CBCT). Methods: Fifty high-resolution CBCT scans of endodontically treated teeth with a diagnosis of fracture were obtained, of which 30 were from women and 20 were from men. These scans were acquired with three Veraviewepocs 3D units and one 3D Accuitomo 170 unit, with a 40 × 40-mm field of view and 125 μm voxel size. The variables assessed included the type of fracture, extent of fracture, type of retention, post length, cause of endodontic failure, location of the lesion, and time required to detect the fracture (difficulty score). For data analysis, the chi-squared test, Student's t-test, and multiple linear regression (α ˂0.05) were used. Results: No association was found between the type of fracture and type of retention or between the type of fracture and its extent (P ˃0.05). On the other hand, the type of fracture significantly influenced the time required for its detection. Additionally, the most difficult plane for detecting the fracture and the difficulty score were associated, with statistically significant results. Conclusions: The type of fracture in endodontically treated teeth was not associated with the type of post used for restoration. All of the CBCT systems used to detect tooth fracture showed the same efficiency. Keywords: Cone Beam Computed Tomography, Tooth Fracture, Root Canal Post, High Resolution

SummaryBackground/Aim: The management of horizontal root fracture is not straight forward. It depends upon the location of the fracture, mobility and vitality of fractured tooth segment. The goal of treatment is to restore the shape and function of affected tooth.Case report: This following case report described the conservative management of horizontal root fracture which was also displaced but somehow maintained its vitality. The affected tooth was initially stabilized and followed up in the subsequent appointments for evaluation of vitality that turned out to be vital, thus, preventing any unnecessary intervention.Conclusions: Horizontal root fractures in the vital teeth should be initially managed conservatively and every effort should be made to preserve the vitality of tooth.
