“…Composite resins are tooth-coloured materials commonly used for aesthetic restorations of anterior and posterior teeth. Composites are polymer matrix filled materials, which derives their physical properties and handling characteristics from loading with reinforcing filler particles and the viscosity of the resin matrix [27][28][29]. They need the application of adhesive systems for adequate bonding and sealing of the restorations [30].…”

Background: Repair of direct composites are less invasive than replacement, diminishing the risk of iatrogenic exposure of the pulp and the risk of detrimental to adjacent teeth, all in all, reducing the procession of the "restoration death spiral". Aim: This study aimed to evaluate the repair bond strength of aged resin composites using different surface treatments and bonding protocols. Materials and methods: A total of 45 discs (n=45) were fabricated of Nanohybrid composite measuring about 2.5 mm in height and 3.5 mm in diameter and were mounted in acrylic resin and subjected to 10,000 thermal cycles between 5-55 ̊ C with 30 seconds of dwell time in a thermocycler in order to simulate artificial ageing. All these samples were assigned into three groups (n=15) based on the surface treatment protocol. According to the bonding protocol, the samples in each group are further divided into three subgroups (n=5). After surface treatments of the aged composites, the application of bonding agent followed by new composite material was performed. All the samples were stored in distilled water at 37 ̊ C for 24 hours. The shear bond strength of the samples was measured using a universal testing machine at a crosshead speed of 1mm/min. Results: Among the groups, the mean bond strength in medium grain diamond bur and 37% phosphoric acid etchant with the universal bonding agent subgroup was higher 852.56±27.71 than the remaining groups. The lowest mean bond strength of 200.9±10.62 was observed in 37% Etchant with direct composite subgroup. Conclusion: Different combinations of surface treatments and bonding protocols affect shear bond strength differently. The highest shear bond strength values were achieved for the group where surface treatment was done with the combination of blue diamond bur and 37% phosphoric acid along with a universal bonding agent.

“…Another feature that is observed is the enhanced fracture toughness and adhesion to tooth tissue [8,9,10,12]. Nanotechnology can improve the continuity between the tooth structure and the nanosized filler particles to provide a more stable and natural interface between the mineralized hard tissues of the tooth and the advanced restorative biomaterials [11].…”

“…Their materialistic properties essentially depend on external stimuli such as pH, temperature, mechanical stress, moisture, etc. [12]. Stimuli responsive composites contain bioactive amorphous calcium phosphate (ACP) filler that responds to environmental pH changes by releasing calcium and phosphate ions and thereby becoming adaptable to the surroundings [13].…”

“…Self-adhering composites are also known as compo-bonds. Self-adhering flowable composite combine the advantages of both dental adhesives and restorative materials technologies (8th generation) into a single product [12,23]. They eliminate the precursory bonding stage necessary to adhere resin to tooth substrate, and therefore reduce the chances of postoperative sensitivity.…”

Composite restorative materials represent a class of unique modern biomaterials since they replace biological tissue in both appearance and function. The early formulations were characterized by problems such as polymerization shrinkage, improper marginal adaptation, inappropriate proximal contact, discoloration or staining and also secondary caries. The need to improve said properties and achieve adequate contact is necessary for dental composites and numerous attempts have been made to accomplish these aims. Newer generation composites have been produced in order to protect the healthy tooth structure, to reduce microleakage and secondary caries formation, increase fracture toughness and to reduce marginal pigmentation and postoperative sensitivity together with developments in technology. This article discusses the advances in resin restorative materials.
