The clinical performance of dental composites has been significantly improved over the past decade through modifications in formulation that include: using more stable polymerization promoters for greater color stability; incorporating high concentrations of finely ground fillers to produce adequate strength and excellent wear resistance while retaining translucency ; adding radiopacifying agents for improved diagnostics; and utilizing dentin adhesives. However, there are problems which limit the use of composites, especially in posterior teeth. The materials remain very technique-sensitive, due to the extensive contraction which accompanies polymerization and negatively influences marginal sealing. In addition, the materials are generally considered to have inadequate mechanical properties and wear resistance in contact areas to serve as total replacements for amalgams. Current efforts are focusing on several areas, including the development of non- or minimally-shrinking dental composites containing spiro-orthocarbonates as additives to dimethacrylates or epoxy-base resins, and the production of alternative filler materials for ideal wear resistance and esthetics. This paper reviews the composition and characteristics of current dental composites, as well as recent areas of study.

The large choice of ceramic materials for an indirect restoration has given clinicians a dilemma when choosing a suitable ceramic for restorations in anterior or posterior teeth. Focusing principally on the most commonly used materials, lithium disilicate and zirconia, the aim of Part 1 of this article is to compare the mechanical properties and aesthetics of these two materials. For strength, zirconia possesses superior physical properties when compared with lithium disilicate. However, in terms of aesthetics, lithium disilicate holds advantages. With both materials having different microstructures, the same cementation protocols cannot be used. Other contemporary ceramic materials are briefly reviewed. Part 2 reviews the latest clinical research on their clinical performance. CPD/Clinical Relevance: Awareness of which ceramic material performs optimally on anterior and posterior teeth is clinically important.

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.

Background:Previous studies have indicated that the clinical performance of direct composite restoration mainly depends on the polymerization shrinkage. The use of micro ceramic inlay technique has proved to be elegant approach to overcome the polymerization shrinkage and improve the marginal adaptation, reduce wear and leakage of posterior restorations.Objectives:To compare the clinical performance between direct composite restorations and indirect micro ceramic composite restorations in occlusal surface of permanent posterior teethof class-I cavity. Results: The result of this study showed that there was no statisticallysignificant difference between two groups in the treatment of occlusal surface ofclass-I cavity of permanent posterior teeth (p > 0.05). It was concluded that indirect micro ceramic composite resin shows no better clinical efficacy than that of direct composite resin in occlusal surface of class-I cavity of permanent posterior teethInternational Journal of Human and Health Sciences Vol. 03 No. 02 April’19.

Objective: To evaluate the 30-month clinical performance of a nanofilled-resin composite with or without glass-fiber layering in restorations of large cavities in posterior teeth of children. Study Design: A total of 71 restorations were placed in permanent molar teeth of 47 children (mean age 10.9 years) with (FRC; n=35) or without (RC; n=36) fiber layering. One operator placed all restorations. Restorations were evaluated according to the USPHS modified-Ryge criteria at baseline, 6, 12, 18, 24, and 30 months. The data were analyzed using Fisher's exact and chi-square tests and outcomes were compared using the Cochran-Q test (p<0.05). Results: The 30-month survival rates of the restorations were 97% and 97.1% in the RC and FRC groups, respectively. Nanofilled-resin restorations with or without glass fiber-layering showed similarly high clinical performance. No differences were detected between the evaluated criteria when comparing baseline with any of the evaluation periods (p<0.05). After 30 months there were no secondary caries, change in anatomical form or postoperative sensitivity. Only minor changes for marginal adaptation, marginal discoloration, color match and surface texture were observed. Conclusion: It was concluded that nanofilled-resin composite applied with or without glass-fiber layering showed similar and good results in large cavities of posterior permanent teeth in children over a 30-month period.

Clinical Relevance The Monobond Etch & Prime seems to be an efficient option for adhesive cementation of ultrathin veneers and full crown ceramic with good properties after two years of clinical follow-up. SUMMARY The use of the self-etching ceramic primer combines the stages of acid conditioning and silanization in cementation procedures of ceramic restorations. The protocol is a simpler and safer alternative to the conventional protocol for surface treatment of silica-based ceramics. This case report describes the steps of an esthetic rehabilitation with ultrathin veneers and full crown based on lithium disilicate treated with a ceramic primer (Monobond Etch & Prime, Ivoclar Vivadent, Schaan, Liechtenstein). After two years of clinical follow-up, the restorations presented satisfactory esthetic and functional performance, color stability, surface and marginal integrity, and absence of cracks and debonding. More research is needed to investigate the clinical performance and longevity of the ceramic restorations treated with self-etching ceramic primers.

Clinical Relevance The clinical behavior of pure ormocer composite is reliable when used in class II restorations after 24 months of evaluation. SUMMARY Objective: The aim of this study was to evaluate the clinical performance of class II restorations made using pure ormocer and methacrylate composites in a period of 24 months, using a split-mouth double-blinded randomized design. Methods and Materials: Thirty patients received two class II restorations (n=60) performed with different composites: GrandioSO (methacrylate, nanohybrid) and Admira Fusion (pure ormocer, nanohybrid). The universal adhesive system (Futurabond M+) was applied in all restorations using the self-etching mode. The composites were placed by the incremental technique. The restorations were evaluated using the FDI World Dental Federation criteria after 7 days and 6, 12, and 24 months postoperatively. Results: After 24 months, 23 patients attended the recall and 46 restorations were evaluated. Fisher's statistical analysis (5%) showed no difference between the materials. One pure ormocer restoration and one methacrylate restoration presented small fractures. Only one tooth suffered a fracture of the remaining tooth structure. Admira Fusion presented, respectively, 100%, 95.66%, and 100% of acceptable performance in general scores for esthetic, functional, and biological properties. GrandioSO presented, respectively, 100%, 91.31%, and 95.66% of acceptable performance in the same scores. Conclusion: After 24-month follow-up, nonsignificant differences between the tested composites was detected. Both materials provided acceptable clinical performance in class II restorations.
