“…Also, the type of incremental technique affects the amount of applied restorative material, and therefore cusp displacement. These findings are in contrast with some studies that stated that the incremental technique reduces the polymerization shrinkage effects 2,21 . In spite of this study's results, the incremental techniques should be used to achieve both good mechanical properties associated with a high rate of conversion and close adaptation of the resin composites to the cavity wall.…”

ABSTRACT:The aim of this in vitro study was to evaluate by spectrophotometry the influence of the incremental technique and progressive light curing in the microleakage of Class V cavities. Forty samples were prepared with class V cylindrical cavities on the buccal root surface of bovine incisive teeth and filled with composite resin (Z250). The samples were divided into four groups: I: cavity was bulk filled and the composite was light cured for 40 seconds; Group II: cavity was bulk filled and a "soft-start" polymerization was used; Group III: cavity was filled with the incremental technique in two coats and light cured for 40 seconds; Group IV: cavity was filled with the incremental technique in two coats and light cured with "soft-start" polymerization. After the restoration, the specimens were thermally stressed for 3,000 cycles in bath at 5 ± 2°C and 55 ± 2°C, protected with nail enamel, colored with 2% methylene blue and cut into sections. These sections were triturated and the dye was recovered with PA ethanol and the supernatant was evaluated. The data were submitted to ANOVA and the results showed the following averages: bulk filled and conventional photopolymerization (I) 0.06075 µg/ml; bulk filled and progressive photopolymerization (II) 0.04030 µg/ml; incremental insertion and conventional photopolymerization (III) 0.04648 µg/ml; incremental insertion and progressive photopolymerization (IV) 0.04339 µg/ml. No significant statistic differences were observed among the mean values. The Degulux "soft-start" equipment probably emits too high initial light intensity to promote progressive photopolymerization. DESCRIPTORS: Dental leakage; Dentin-bonding agents; Composite resins. RESUMO:O objetivo deste estudo in vitro foi avaliar através de espectrofotometria a influência das técnicas de inserção incremental e de fotopolimerização progressiva na microinfiltração de cavidades Classe V. Foram preparadas 40 cavidades cilíndricas na superfície radicular vestibular de incisivos bovinos e preenchidas com resina composta (Z250). Os espécimes foram divididos em quatro grupos: I: a resina foi inserida em camada única e fotopolimerizada por 40 segundos; II: a resina foi inserida em camada única e fotopolimerizada progressivamente com um aparelho "soft-start"; III: a resina foi inserida em duas camadas e fotopolimerizada por 40 segundos; IV: a resina foi inserida em duas camadas e fotopolimerizada progressivamente. Em seguida os espécimes foram submetidos a 3.000 ciclos térmicos a 5 ± 2°C e 55 ± 2°C, preparados, corados com azul de metileno a 2%, seccionados, triturados e avaliados em espectrofotometria para se quantificar o corante infiltrado. Os dados foram submetidos a ANOVA. Os resultados demonstraram as seguintes médias: inserção única e fotopolimerização convencional (I): 0,06075 µg/ml; inserção única e fotopolimerização progressiva (II): 0,04030 µg/ml; inserção incremental e fotopolimerização convencional (III): 0,04648 µg/ml; inserção incremental e fotopolimerização progressiva (IV): 0,04339 µg/ml.

“…An incremental build‐up technique (13) is considered to be the optimal technique for the placement of composite resins. The reasons for this are to ensure complete penetration of the curing light through the composite and to minimize contraction stresses during polymerization.…”

This prospective split-mouth clinical trial evaluated the performance and patient satisfaction of 168 Herculite XRV direct composite restorations bonded to the worn anterior dentition of 18 patients with localized anterior tooth surface loss. One hundred and six of these restorations were placed on the mandibular anterior teeth. The restorations increased the anterior occlusal vertical dimension between 0.5 and 5 mm and the posterior occlusal contacts were restored after a mean duration of 6.2 months (range: 3-13 months) in 14 out of the 15 'Dahl' sub-group patients. The restorations were evaluated after 2.5 years of service by five examiners. Four patients and 23 mandibular restorations were lost to follow-up. Multiple clinical and restorative variables were assessed to determine their influence on restoration performance. Complete failure occurred in 6% of the restorations. Circumferential preparation and height of the restorative addition did not influence the performance of the restorations. A Visual Analogue Scale (VAS) was used to assess the patient's opinion regarding sensitivity, aesthetics, longevity and function of the worn mandibular anterior teeth. A statistically significant difference (95% CI) was found between the pre-operative and 1-month review VAS responses for aesthetics and longevity and this was maintained at the 2.5-year review. Direct composite restorations placed at an increased occlusal vertical dimension are a simple and time-efficient method of managing the worn mandibular anterior dentition. Patient's acceptance and adaptation to the technique is good and the results are accompanied with a high level of patient satisfaction that is maintained for the medium-term.

“…7 The restoration was progressively built up with photoactivation following each increment (1200 mW/cm² for 40 s) using an LED light (Bluephase, Ivoclar-Vivadent, Schaan, Liechtenstein). All specimens were subjected to compressive axial loading (0.5 mm/min.)…”

Fracture resistance of teeth restored with different resin-based restorative systems

The aim of the present study was to evaluate the fracture resistance of teeth restored with resin composite. Forty-eight maxillary premolar teeth were chosen and randomly divided to six groups: G1 (control): sound teeth; G2: MOD preparation, unrestored; G3: MOD + Adper Single Bond 2 / P60; G4: MOD + Adper Easy One / P60; G5: MOD + P90 restorative system; G6: MOD + Adper Easy One / P90 Bond / P90. Specimens were subjected to compressive axial loading (0.5 mm/min). Flexural strength and the modulus of elasticity were also tested (n = 7). The only statistical equivalence with sound teeth was noted for G3 (p < 0.05). Flexural strength and the modulus of elasticity varied among the composites tested (n = 10). The reestablishment of the resistance to fracture in premolars subjected to Class II MOD preparations is restorative-system-dependent. The silorane restorative system is not able to recover the resistance to fracture.
