“…If we add the right type of fiberglass pin diameter according to the region where the FRCB is located (anterior sector: Φ 0.8 to 1 mm: posterior sector: Φ 1 to 1.4 mm), we will achieve greater success in our treatment. In 2017, Saritha et al [30] carried out a study comparing the resistance to a fiberglass pin fracture (similar to our what we used) versus a zirconia pin or a carbon pin. The authors confirmed that the zirconia pin was the most resistant, but that it had more disadvantages related to the handling of the material and the modulus of elasticity of the tissue to be replaced (dentin) compared to the pins made of fiberglass.…”

The use of fiberglass in dentistry has increased due to the improvements in the development of adhesive techniques reducing the cost of treatment and avoiding abutment tooth craving. The present study aims to evaluate the clinical usefulness of the new technique to fabricate a direct fiber-reinforced composite bridge (FRCB) over a long period of time. Twenty-one FRCB were performed with the new direct technique on 21 patients with a mean age of 58.85 years and female predominance in the Faculty of Dentistry of Oviedo (Spain). The framework design releases the embrasures allowing adequate interproximal brushing, avoidance of periodontal disease and interproximal caries. A baseline examination was performed and the patients were examined regularly at six-month intervals (nine years’ follow-up). The restorations were also evaluated by an examiner using parameters to check their stability, longevity and the lack of periodontal disease. The most frequent location was the maxillary premolar region and the purpose of the restorations was to give a definitive bridge in 100% of the patients. Only one total debonding of the prostheses was detected during the observation period at 24 months and three partial adhesive–cohesive veneering composite fractures at the pontic after 60, 72 and 84 months, respectively. Kaplan–Meier was performed to detect the overall survival rate of the restorations at the end of the follow-up. Nine-year survival rates for the FRCB was 95.2%. All the cases had a clinically acceptable periodontal condition and an interproximal absence of caries in the abutment teeth. Currently, this type of restoration allows a minimally invasive aesthetic and is an affordable procedure, being a good alternative to other types of treatments.

“…27 This study revealed that amalgam was preferred as core build-up material on the basis of strength. Endo-post was preferred for ETT in order to avoid fracture 28 and majority of the participants preferred PFM as crown material in ETT. Furthermore, it was observed that PFM was more popular among dentist in teaching institutes of Multan, irrespective of their post-graduation qualification and work place.…”

The purpose of this study was to describe the knowledge, attitude and practice for core build-up and crowning of endodontically treated teeth in teaching institutes of Multan and to assess the association of clinical experience, work place and qualification on these options. METHODOLOGY: A cross sectional study was conducted using self-applied questionnaire with dentists working in three teaching institutes of Multan from 22nd to 28th October, 2019. The calculated sample size for the total population of 160 was 114 according to Raosoft sample size calculator by keeping the confidence level 95%. A total of 160 questionnaires were distributed. Recovered questionnaires were 148. Response rate was 92%. Information about clinical experience, work place and post-graduation qualification was collected. Data regarding preference of core build-up material, crown material, timing of restoration of endodontically treated teeth (ETT), type of post was collected. Data were analyzed by SPSS version 22, frequencies and percentage were obtained. Association between different variables was calculated using Pearson's chi-square test. RESULTS: Amalgam was preferred as core buildup material on the basis of strength (81%), immediate restoration of ETT was preferred by private sector participants (30%) and restoration after one week was preferred by public sector participants (45.9%). Most of the participants believed core buildup must receive endopost to have better prognosis (60%). Majority preferred prefabricated endopost (50%) over custom made post (33%). The porcelain fused to metal crown was preferred as the clinical experience of dentist increases (p=0.001). CONCLUSION: Within the limitations of the study, it was concluded that amalgam was preferred as core buildup material, prefabricated post was preferred over custom made and PFM was material of choice for crowning.

“…Success of post and core treatment depends on case selection, type of post and core used, adhesive resin cement, and operator caliber. [6] Post restoration depends on esthetic requirements, amount of remaining tooth structure, tooth position, and functional load on tooth. [7] Posts can be classified as custom made or prefabricated, metallic or nonmetallic, flexible or stiff, and esthetic or nonesthetic types.…”

Aim: This study aimed to evaluate the fracture resistance strength of different post systems in endodontically treated teeth. Materials and Methods: Freshly extracted 60 single-rooted first premolars were selected for this study. Conventional step-back technique was used to prepare a canal for all the teeth. Obturation was carried out and post space was created using a Peeso reamer. All teeth were randomly divided into three groups of 20 samples in each group: Group I, teeth inserted with prefabricated carbon posts; Group II, teeth inserted with prefabricated zirconia posts; and Group III, teeth inserted with prefabricated everStick posts. Core buildup was performed using light-cured composite resin. Compressive load required to fracture the tooth was measured using a universal testing machine. Results: The compressive strength of zirconia posts was highest with a mean of 796.10 ± 20.78 followed by carbon posts (628.22 ± 18.11) and lower compressive strength was exhibited by everStick posts (534.13 ± 19.98). An analysis of variance revealed a statistically highly significant difference ( P < 0.005) among the different posts used, and a statistically significant difference between carbon posts vs. zirconia posts, carbon posts vs. everStick posts, and zirconia posts vs. everStick posts ( P < 0.05). Conclusion: Zirconia posts show the maximum fracture resistance than the carbon posts and everStick posts.
