“…1,2 Recent clinical studies and meta-analyses have established that repair is an alternative to replacement of defective restorations and increases the longevity of restorations with minimal intervention. 3,4,5 The total replacement of defective restorations may result in the loss of healthy dental structure and cause injury to the dentin-pulp complex. 6,7 The concept of repair instead of restoration is part of the philosophy of minimally Declaration of Interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”

The present study aimed to evaluate effects of different surface treatments and aging of composite cylinders on bond strength of composite resin repair. Thirty-two composite cylinders were produced and divided into four groups according to type of surface treatment and storage time of composite cylinder and repair. Cylinder surface of control group (G control ) received no treatment before composite repair. Other groups were sandblasted with aluminum oxide (G Al2O3 ), followed by silane (G Al2O3sil ) or adhesive (G Al2O3ad ). Composite cylinders were stored in artificial saliva for either 24 hours or 1 year. Repairs were performed and stored in artificial saliva for 24 hours or 1 year and repair strength was evaluated using microtensile bond strength test. Data were submitted to Student's t test, two-way ANOVA, and post hoc test for storage time and treatment (α = 0.05). G control group showed lower values of aging of composite cylinder and storage time of repair (24 hours or 1 year for both) compared with other groups (p < 0.05). G Al2O3ad and G Al2O3sil groups did not exhibit decreased microtensile bond strength with aged repairs (1 year; p > 0.05). Polymer degradation was significant for composite cylinders during the first year of storage in G control , G Al2O3 , and G Al2O3ad groups (p < 0.05). In G Al2O3sil group, storage time of composite cylinders was not significant (p > 0.05). Aging of composite resin influenced bond strength of restoration repair for up to 1 year. Sandblasting with Al 2 O 3 , followed by application of silane layer, produced high bond strength after composite or repair aging.

“…Dentin presents a chromatic translucency, with its saturation increasing over time [19]. However, enamel has the ability to present either chromatic or achromatic translucency [20]. Enamel and dentin composite resin have different compositions which try to reproduce the properties of tissues.…”

“…This performance was based on the following parameters: marginal adaptation, secondary caries, and anatomy [22]. It should be noted that the repair of composite should be the treatment of choice when it is clinically indicated, since it is a minimally invasive treatment that can increase consistently longevity of the restoration [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The success of direct adhesive restorations depends directly on the formation and stability of an excellent hybrid layer [23].…”

“…In this study, seeking excellent adhesion between composite and enamel/dentine in addition to use of an adhesive system of three steps, we used the chlorhexidine after acid etching. Chlorhexidine has the ability to inhibit metalloproteinases and Cisteine Catpsine that are enzymes collagenolytic found in the dentin [15][16][17][18][19][20][21][22][23][24][25]. These enzymes, once activated by acid etching, can degrade collagen fibrils including the adhesive system that infiltrate to form the hybrid layer.…”

This work aims to present a technique for resolving cases with aesthetic requirements using guides that facilitates the implementation of restorative procedures without the need for high manual sculpture skill to dental professional and reduced time. Fractures and wear tooth, poor dental position, trauma and dissatisfaction aesthetics are the major causes of seeking patients by the dentist. All these problems could be rehabilitated with indirect or direct restorations. The choice of the ideal material should consider some factors, such as the rehabilitation area, space available, the aesthetical potential of each material, the translucency of the adjacent teeth, type of reminiscent and antagonist that occlude with the new restoration. Direct restorations have good predictability, resistance load, longevity and compared with indirect restorations have greater preservation of dental tissues, low cost and fewer clinical sessions. However, restorative aesthetic works mainly require skill and practice of the dentist. The clinical case shows an alternative technique for performing aesthetic rehabilitation treatment with direct restorations with resin composite. The described technique was an excellent choice to ensure proper sculpture and anatomy of the anterior teeth. Respecting the principles of adhesion and operative procedures for performing direct restorations was possible to obtain an aesthetic and functional result favorable in less time.

“…The question then becomes, “Exactly how ‘large’ does a restoration have to be in order to justify recommending a crown for the tooth?” Some dentists might repair a particular restoration, others may replace it, and still others may recommend placing an inlay or a single-unit crown. 4–6 …”
