“…In addition to the direct technique of incrementing restorative materials in NCCL, the semi-direct technique can be performed. Published in 2019, Caneppele et al 52 performed a two-year randomized clinical evaluation of resin composite with direct and semi-direct technique in NCCL restorations. The results showed greater failures in the semi-direct technique, for the authors this technique was not shown to be advantageous, for presenting greater clinical preparation time compared to the direct technique and for the difficulty of working with a small fragment of extra oral restoration, requiring the professional skill and knowledge.…”

Objective: To review the available scientific literature on the restorative treatment of non-carious cervical lesions; in particular, the restorative materials that present optimal performance in this type of clinical situation. Methods: A literature review was performed using Pubmed search engine with the aim of determining the ideal restorative material for restorations of non-carious cervical lesions. Results: Beautifil II (Shofu INC.) restorative material showed satisfactory results in terms of fracture resistance, flexural strength and excellent aesthetics, in addition to components that act as anti-cariogenic, anti-plaque and oral pH balance. The Clearfil SE Bond adhesive (Kuraray NORITAKE) showed in clinical research the highest bond strength rate compared to other adhesive systems available in the dental market. Conclusion: Non-carious cervical lesions are multifactorial lesions that require the professional knowledge to conduct the treatment effectively. The Shofu Beautifil II showed the best results in fracture resistance, flexural strength and excellent aesthetics, it has anticariogenic potential, anti-plaque bacteria and contributes to the oral pH balance. The Clearfil SE Bond adhesive showed the highest retention rate among its competitors. Keywords: Restorative materials; non-carious cervical lesions; class V

“…The semi-direct technique, also called direct-indirect by Fahl, 6 is a restorative technique that uses composite resins for posterior and anterior teeth. 2 , 6 , 7 In this technique, the resin is inserted, settled, shaped, and polymerized in the dental preparation, and later removed. Finishing and polishing are performed extraorally and then cemented in the dental preparation.…”

“…Finishing and polishing are performed extraorally and then cemented in the dental preparation. 6 , 7 The procedure allows photoactivation of the material from different directions, ensuring a greater range of light in the material. Moreover, it is more comfortable for the patient due to a reduction in intraoral working time; however, it has a limitation of increased working time by the patient chair.…”

“…In the semi-direct technique, apart from photoactivation in different directions, 7 it is possible to add post-curing techniques with the additional use of light, heat, and pressure, either alone or together, to increase the degree of conversion of composite resins, providing complete polymerization and consequently an improvement in physical and mechanical properties. 3 , 8 Thus, the chemical degradation of composite resins that occurs mainly due to the diffusion of molecules and non-reacted monomer ions 8 could be reduced.…”

Background. Post-cured composite resins exhibit improvements in physical and mechanical properties due to additional polymerization conversion. However, the post-curing techniques might influence the color stability of composite resin materials. Thus, this study evaluated the color stability of a nanofilled composite resin (Filtek Z350 XT - 3M ESPE) subjected to different post-curing techniques. Methods. Sixty samples (color A2) were randomly allocated to six experimental groups (n=10): G1: photoactivation (P) (control); G2: P + microwave oven with distilled water; G3: P + microwave oven without distilled water; G4: P + conventional oven; G5: P + dry-heat sterilizer; G6: P + steam autoclave. All the groups were stored in distilled water for 60 days and immersed daily in 5 mL of a coffee solution for 3 minutes. The color readings (CIEL*a*b* system) were performed at two different time intervals, initially and after 60 days, in a reflectance spectrophotometer (UV-2600; Shimadzu). The colorimetric readings were performed using the Color Analysis software (CIEL*a*b* system). Results. Group G6 exhibited significantly low values of total color change (ΔE=13.16). The control (ΔE=15.32) and G5 (ΔE=15.49) groups exhibited intermediate values, with no difference between them. In turn, the groups in which the resin was heated in a microwave (G2 ΔE=18.55 and G3 ΔE=19.45) exhibited the most significant color changes (one-way ANOVA and Tukey test, P≤0.05). Conclusion. Steam autoclave post-polymerization increased the color stability of the nanofilled resin subjected to artificial aging and coffee immersion.
