Purpose: This clinical case discusses the step-by-step implementation of a core and a post system that uses a single resin composite material for cementation of a glass fibre post and core build up of a fracture endodontically treated maxillary left first premolar with gingivectomy as a crown lengthening procedure. Clinical considerations: Several materials and methods has been discussed in the literatures regarding restoration of endodontically treated teeth with minimal tooth structure left which require fibre post and core build up. Gingivectomy as a crown lengthening is also a common procedure that facilitates restorative dentistry. This case presents a restoration of a tooth with a short clinical crown by gingivectomy and post core build up by glass fibre post with a mono-block technique or core-and-post technique with dual cure composite resin as a luting and core build up material. Conclusion:Post and core is needed to restored tooth with little tooth structure remaining.Glass fibre post are prefabricated posts which makes it easy to manipulate and reduces chairs side time among other advantages. Use of single material system for post-and-core reduces the steps of manipulation and chair side time compared to conventional techniques. Clinical significance: More measures are required when different materials are used for post-cementation and core build-up, increasing the chair time and the number of interfaces between the materials. However, these shortcomings can be overcome by the mono-block technique where only one material is used for both cementation and core build up. Update Dent. Coll. j: 2021; 11(2): 38-42

Reconstruction of endodontically treated teeth is common procedure in everyday clinical practice. It has great impact on prognosis of endodontically treated teeth, however, there is no consensus regarding the most predictable restorative procedure. Widely accepted procedure has included the use of post and core and crown. Nowadays, sound tooth structure preservation has become one of the most influencing factors in terms of survival rate of treated teeth. Therefore, direct restorations have become more advantageous as compared to crowns. This article is a review about conservative reconstruction of endodontically treated posterior teeth. The purpose was to give the guidelines for clinicians how to choose the most successful therapeutic procedure for each individual case.

Endodontically treated teeth (ETT) have been problematic in most cases as a result of dental caries, fractures, previous restorations and endodontic procedures. Several post system techniques and materials are currently used to build up ETT with moderate or severe loss of coronal tooth structure and to retain final restorations. Following root filling, the custom-made cast metallic post and core with metal-ceramic crowns was the traditional restoration of choice, but this has changed. The patients’ primary motivation for seeking superior dental aesthetics, particularly in the anterior aesthetic zone, has prompted the development of non-metallic restorations. Several new types of polymeric and more aesthetic quartz and glass-fibres posts, combined with direct resin composite cores, provide an aesthetic foundation for an all-ceramic crown and have overcome the aesthetic limitations of metallic posts and cores in the anterior teeth. Until recently, there has been controversy in the dental community regarding which material or technique is the most favourable for the restoration of ETT. It seems that the amount and retentive capacity of the remaining tooth structure, the position of the tooth in the dental arch, the functional or para-functional loading on the tooth, and the treatment plan to restore aesthetics and function all influence the selection of the most appropriate post system for each case.  Hence the present study was planned for Evaluation of Different Types of Crowns Used For Restoration Of Endodontically Treated Teeth. The present study was planned in Department of Conservative Dentistry and Endodontics, Buddha Institute of Dental Science and Hospital, Patna, Bihar, India. The 40 cases of maxillary anterior endodontically treated teeth (ETT). The roots were restored with reinforced GFPs (Relaxy Fiber Post, 3M ESPE, Germany), and composite resin cores (Tertic-N-Ceramic, Ivoclar Vivadent, Lichenestine). The survival of ETT is contingent on the residual sound tooth structure that remains after the endodontic access and caries removal are performed consequently the most important factors upon restoring ETT become the maximum preservation and conservation of enamel, dentin and the dentinoenamel junction. Hence, bonded partial restorations are always preferred over full coverage cementable crowns. More clinical studies comparing adhesive crowns bonded to postless build-ups or post and -core build-ups are needed for a better understanding of postless approaches in biomimetic restorative dentistry.

Endodontically Treated Tooth

The restoration of a root canal treated or, endodontically treated teeth, is often can be achieved with post and core because of the significant loss of tooth structure. Until the mid-1980s, the safest way to restore an endodontically treated tooth was considered to be the cast-metal post, made indirectly by a dental technician. Also prefabricated metal posts in combination with different core materials under artificial crowns were used. The development and use of fiber reinforced composite (FRC) root canal posts over metallic posts make possible of the attachment & reinforcement of the crown with maximum esthetics. This paper illustrates a technique for rehabilitation of an endodontically treated maxillary central incisor of both sides (UL1 & UR1) with a fiber reinforced composite post (FRC post) & discusses the advantages, disadvantages of metallic post over fiber reinforced composite (FRC) posts.DOI: http://dx.doi.org/10.3329/bjdre.v3i1.16595 Bangladesh Journal of Dental Research & Education Vol.3(1) 2013: 45-48

Resistance Form

Due to substantial loss of coronal tooth structure, corono-radicular stabilization is often required, especially in anterior teeth to provide retention and resistance form for the restoration. The use of ferrule as a part of the artificial crown was proposed in reinforcing the root-filled teeth. The purpose of this study was to investigate the effect of the ferrule height on stresses induced in an endodontically treated maxillary central incisor, which was restored with pressed ceramics, using numerical analysis. The study was developed for in order to obtain 3D models, for the design of the prepared teeth, pressed ceramics post and core systems and crowns. The use of ferrule as a part of the core was proposed in reinforcing and therefore six levels of the ferrule height were designed in order to be investigated. The study was performed on a central upper incisor, using a finite element analysis. Von Mises equivalent stresses were calculated and their distribution was plotted graphically. Regarding stress distribution in the crown high stresses are present cervical. In the prepared root stresses are under the finishing line and in the post cervical. In the post, with the increase of the ferrule height, the stresses move in coronal direction. No significant differences were found between the maximal stress values for the studied preparation designs (a ferrule height between 1 and 6mm).

Introduction: Endodontically Treated Teeth (ETT) are most likely to get fractured, if it is left unrestored compared with the vital teeth due to the loss of tooth structure and reduced modulus of elasticity. Aim: To gain insight into the rationale for choice of endodontic posts and the different endodontic post systems currently used by dental practitioners in western region of Saudi Arabia. Materials and Methods: For this survey-based study, a questionnaire was designed consisting of eight questions to assess the details of why, when and how general practitioners restore ETT and to determine contemporary use of endodontic post from 1st of November 2018 till the end of January 2019. This questionnaire was sent online to 250 private dental practitioners in western region of Saudi Arabia, out of which 202 participants responded. Data was entered in the excel sheet. Descriptive statistics like frequency and proportion was calculated for qualitative data. Results: This study included 202 participants with the mean age group of 25-50 years, out of which 108 (53.4%) male participants and 94 (46.5%) female participants. 120 (59%) of the study sample were general practitioners and 82 (41%) of them were specialists. A total of 60 (29.70) of the study sample were into general practice, reported restoring ETT with post and core followed by the crown, whereas, 30 (14.85%) of them did the crown without post, 15 (7.42%) of them completed restoration with composite and 15 (7.42%) of them did build-up with post and core. An 82 (40.59%) of the study sample who were specialists, reported restoring ETT with post and core build-up and then proceed with crowns. An 80 (39.60%) of the study sample were into general practice, reported using prefabricated fiber post whereas, 23 (11.38%) of them using cast post and 17(8.41%) of them using prefabricated metal posts. 72 (35.64%) of the study sample were specialists reported using prefabricated fiber posts and 10 (4.95%) of them used cast metal post. Conclusion: Based on the results of the study, it can be concluded that majority of the participants practiced reinforcement of ETT by using fiber posts with resin cements followed by crowns.

Abstract Aim The purpose of this study was to compare the fracture resistance of endodontically treated teeth restored with different post and core systems in combination with complete metal crowns in teeth with no coronal structure. Methods and Materials Fifty extracted mandibular premolars were divided into five groups. The coronal portion of each tooth was removed at the cementoenamel junction (CEJ) in all groups except Group 1. In this group the teeth were sectioned 1 mm above the CEJ to create a ferrule. After root canal preparations, cast posts were placed in the first four groups. Prefabricated glass fiber posts and composite cores were placed in the fifth group. An opaque porcelain layer was applied to the metal post surfaces in the third group and an alloy primer was applied to the posts in the fourth group before using Panavia F2 resin cement. No bonding agent or surface treatments were used for the first and second groups. A Ni-Cr full cast crown for each sample was prepared and cemented. A compressive load was applied at an angle of 45 degrees to the crown with a universal testing machine. After 500,000 mechanical cycles at 1.5Hz, the maximum load at fracture (N) was recorded. Results Significantly higher fracture resistance values (216.87 N) and survival rates (75%) were demonstrated for non-ferrule teeth restored with opaque layered posts than for other non-ferrule groups. The prefabricated post group showed the most favorable fracture pattern in all test groups (P=0.04). Conclusion Either a ferrule preparation or bonding with the use of an opaque porcelain layer can increase the fracture resistance of teeth with little remaining tooth structure that are restored with cast crowns following endodontic therapy. Clinical Significance Bonding cast posts to the tooth structure has a significant effect on compensating for the lack of a ferrule on endodontically treated teeth.

Introduction. Reconstruction of endodontically treated tooth (ETT) is one of the greatest challenges in dentistry. Clinical success of fiber reinforcement composite (FRC) restorations in ETT depends on many factors like remaining tooth structure, knowing advantages of adhesive dentistry besides its drawbacks, and the correct use of fibers in combination with resin composite. Case Report. This article presents a case in which fibers have been used in composite buildup in order to increase the toughness and strength of the ETT direct restoration. In addition, this technique does not require root canal enlargement to eliminate the risk of root perforation. Also, this one visit treatment can be helpful for patients that could not pay the cost of indirect restoration and/or have no time. Conclusion. It seems in selected patients with special considerations, FRC composite restoration is valid alternatives for indirect restoration.

The Relationship

<p><strong>Purpose: </strong>To investigate the relationship between post and core build-up materials on the fracture resistance of endodontically treated teeth restored with different onlay restorations. Methods: 60 mandibular molars were endodontically treated and divided into three experimental groups that received one of the following onlay restorations: gold onlays, glass ceramic onlays, or resin composite onlays. Half of the specimens in each group received a fiber post (n = 10). Two controls groups (n = 10) were included: one group composed of sound mandibular molars, and the second group was composed of endodontically treated unrestored molars. Fracture tests were carried out by applying axial load using a universal loading machine until fracture. All fractured specimens were fractographically examined using a scanning electron microscope. Data were analyzed using two-way ANOVA and Tukey multiple comparison tests (α = 0.05). Results: Statistical analysis showed that restoration of endodontically treated teeth with gold onlays improved fracture resistance when compared to glass ceramic or resin composite onlays. The presence of a fiber post significantly improved (P&lt; 0.045) fracture resistance of gold onlays from 2271 to 2874N while it did not influence the performance of the other two groups. Fractographic analyses revealed that the presence of fiber post resulted in more restorable fractures due to better stress distribution of the applied load. All onlay systems resulted in significant improvement of the fracture resistance compared to unrestored teeth (711N) but neither of them resulted in restoring the fracture resistance to match that of sound teeth (3212 N).
