This preliminary clinical trial evaluated 12 month clinical performance of novel filling composite resin system which combines short fiber-reinforced composite resin and conventional particulate filler composite resin in high stress bearing applications. A total of 37 class I and II restorations (compound and complex type) were placed in 6 premolars and 31 molars. The restorations were reviewed clinically at 6 months (baseline) and 12 months using modified USPHS codes change criteria for marginal adaptation, post-operative sensitivity, pulpal pain and secondary caries criteria. Photographs and x-rays were obtained for restorative analysis. Results of 12 months evaluation showed 5 restorations having little marginal leakage (B score) and 1 patient had minor pulpal symptom and post-operative sensitivity (B score). No secondary caries or bulk fracture was detected. The majority of restorations exhibited A scores of the evaluated criteria. After 12 months, restorations combining base of short fiber reinforced composite resin as substructure and surface layer of hybrid composite resin displayed promising performance in high load bearing areas.

Objectives: The aim of this study was to evaluate the clinical performance of posterior composite restorations reinforced by bulk base of short-fiber composite (everX Posterior, GC Corporation). Methods: Thirty-six short fiber-reinforced composite restorations were placed in premolar and molar teeth of 33 patients. Eight of the teeth were vital and 28 were non-vital. Average follow up time of the restorations was 30.6 months (2.5 years), ranging from 16.2 to 51.3 months (1.3 - 4.3 years). Results: One restoration failed during the follow-up period due to secondary caries, at time point 39.5 months. Three fillings had minor fractures during the follow-up. The overall survival rate of the restorations was 97.2% and success rate (no maintenance needed) was 88.9%, respectively. Conclusion: Posterior composite restorations with a bulk base of short-fiber composite showed good clinical performance in the short term evaluation.

Composite Resin Restoration

Gumboil is inflammation reaction in the gum caused by pulp infection. Gumboil is seen as an oral lesion characterized by a soft erythematous papule where a periapical abcess is draining into the oral cavity. An adequate root canal treatment can  cure gumboil and remove bacteria from the root canal. To support the success of root canal treatment, final restoration used in this case is composite resin restoration with reinforcing fiber (short fiber reinforced composite). The purpose of this treatment was to restore the functions of tooth in mastication and preserving the supporting tissue. A female patient age 23 years old came with complaints of pain in the lower right mandibular molar accompanied by swelling of the gums around the teeth since a week ago. Swelling is intermittent since last 3 months. The tooth have been restored for about 3 years ago. Clinical examination showed a positive percussion, positive palpation, negative vitality, and negative mobility. Radiographic examination showed bifurcation and periapical lesions. Root canal treatment is performed with crown down preparation technique and followed by direct composite resin restoration with short fiber reiforced composite. The success of root canal treatment followed by composite resin restoration with short fiber reinforced fiber is marked by the absence of complaints as well as the dissappearance of gumboil.

ABSTRACT Introduction The early loss of deciduous molars is a frequently encountered problem in dentistry. Various space maintainer designs were developed to prevent the loss of the space. The aim of this study was to evaluate long-term clinical performance and survival rates of fiber-reinforced composite resin (FRCR) as a space maintainer clinically. Materials and methods This study was designed on 44 children who had early missed deciduous molars. Space maintainers were prepared on plaster models of patients and fixed directly to the adjacent teeth. Survival rate and whether it causes any damage to adjacent teeth were examined clinically and radiographically for 24 months or until failure. Kaplan–Meier survival analysis was used for the statistical analyses. Results Overall, 16.2% of space maintainers were dislodged and accepted to be failed at the end of 12 months. At the 24-month control, 52.2% success was stated with the FRCR space maintainer and because of permanent tooth eruption, 31.8% of space maintainer were taken out. The mean duration of space maintainers was measured to be 14.8±3.48 months. There was no statistical significance between survival time and gender, tooth number, localization, and measured space (p > 0.05). Conclusion After all 24 months follow-up, as well as esthetic properties of FRCR space maintainer, their applicability in a single seance and strength against the forces are determined as the advantages of the technique. Clinical significance The FRCR space maintainers can be thought of as alternatives to metal space maintainers. How to cite this article Kirzioğlu Z, Çiftçi ZZ, Yetiş CÇ.

ABSTRACT Aim Fracture of restorative composite is reported as a common reason for replacement. Due to failures of this kind, it is still controversial whether restorative composites should be used in large, high-stress-bearing applications, such as in direct posterior restorations. The high brittleness of current composites hinders their use in large stress-bearing areas. Thus, recently short fiber-reinforced composite was introduced as dental restorative composite resin. The aim of the article is to evaluate shear bond strength of fiber-reinforced composite (everX Posterior) and methacrylate-based composite (FILTEK Z250) to pure tricalcium silicate-based cement (biodentine). Materials and methods Acrylic blocks (n = 30) with 2 mm high and 5 mm diameter central holes were prepared. The samples were taken and filled with biodentine and were divided into two groups containing 15 in each group. Group I: Fiber-reinforced composite. Group II: Methacrylate-based composite, which are layered over biodentine. The specimens are transferred to the universal testing machine and subjected to shear bond strength analysis at a cross-head speed of 1.0 mm/minute. Results The bond strength values were significantly higher in case of fiber-reinforced composite when compared with methacrylate-based composite. Conclusion Within the limitations of the study, it was concluded that the fiber-reinforced composite with biodentine had highest bond strength when compared with methacrylate-based composite. Clinical significance Fiber-reinforced composite has excellent fatigue resistance because the embedded fibers are bonded to the polymer matrix and allow the stresses to be distributed effectively throughout the restoration. They are most suitable for applications in which the direction of highest stress is predictable. They are used in cavities with three or more surfaces missing and also in large-sized cavities. They are extensively used in cavities where inlays and onlays are prescribed. How to cite this article Reddy RA, Basavanna RS.

The purpose of this paper was to investigate, by means of marginal adaptation and fracture strength, three different types of single retainer posterior fixed partial dentures (FPDs) for the replacement of a missing premolar. Two-unit cantilever FPDs were fabricated from composite resin, feldspathic porcelain, and fiber-reinforced composite resin. After luting procedures and margin polishing, all specimens were subjected to a Scanning Electron Microscopic marginal evaluation both prior to and after thermomechanical loading with a custom made chewing simulator comprising both thermal and mechanical loads. The results indicated that the highest score of marginal adaptation, that is, the closest score to 100% of continuous margins, at thetooth-composite resininterface was attained by the feldspathic porcelain group (88.1% median), followed by the fiber-reinforced composite resin group (78.9% median). The worse results were observed in the composite resin group (58.05% median). Fracture strength was higher in feldspathic porcelain (196N median) when compared to resin composite (114.9 N median). All the fixed prostheses made of fiber-reinforced composite resin detached from the abutment teeth before fracturing, suggesting that the adhesive surface's retainer should be increased.

Objectives: To determine the static load-bearing capacity of direct composite onlay restorations made of novel filling composite resin system which combines short fiber-reinforced composite resin (FC) and conventional particulate filler composite resin (PFC). Methods: Three groups of onlay restorations were fabricated (n = 8/group); Group A: made from conventional particulate filler composite resin (Z250, 3M-ESPE, USA, control), Group B: made from short fiber-reinforced composite resin (EverX posterior, StickTeck Ltd, member of GC group, Turku, Finland) as substructure with 1 mm surface layer of PFC, Group C: made from FC composite resin. The specimens were incrementally polymerized with a hand-light curing unit for 80 s before they were statically loaded with two different sizes (3 & 6 mm) of steel ball until fracture. Failure modes were visually examined. Data were analyzed using ANOVA (p = 0.05). Results: ANOVA revealed that onlay restorations made from FC composite resin had statistically significantly higher load-bearing capacity (1733 N) ( p < 0.05) than the control PFC composite resin (1081 N). Onlays made of FC composite resin with a surface layer of PFC gave force values of 1405 N which was statistically higher than control group ( p < 0.05). No statistically significant difference was found in the load-bearing capacity between groups loaded by different ball sizes Significance: Onlay restorations combining base of short fiber reinforced composite resin as substructure and surface layer of conventional composite resin displayed promising performance in high load bearing areas.
