“…Modifications in filler content, the use of additional or more efficient photo-initiators, and/or the use of novel resin monomers and additives providing reduced stress are some of approaches used by manufacturers of bulk-fill composite to allow for the composite to be inserted using this technique (31,32). However, the insertion of socalled conventional composites using increments thicker than 2-mm has been used and evaluated for quite some time (32,33). As the results of the present study seem to suggest, the use of increments thicker than 2 mm might be possible for certain shades of composite.…”

This study aimed to evaluate the effect of the composite shade and distance from the light-curing unit (LCU) tip on the irradiance reaching the bottom of composite disks and on the depth of polymerization. Composites of three shades (opaque -OXDC, bleach -BXL, and A2) were inserted into molds with 3-mm of thickness positioned over a spectrometer and photo-activated with the LCU (Bluephase) tip placed at 0 or 1 cm from the composite surface. The mean irradiance reaching the bottom of composite was recorded during the entire photo-activation (30 s). Specimens (2 x 2 x 4 mm) were polymerized and used to map the degree of conversion achieved in different depths from irradiated surface. Specimens were sectioned into slices that were positioned over the platform of the infrared microscope connected to the spectrometer to map the conversion. The conversion was measured in eight different depths every 500-µm. Increasing the distance of LCU tip reduced the irradiance only for A2. Interposing OXDC disks resulted in lowest values of irradiance and A2 the highest one. A tendency to decrease the conversion was observed towards the bottom of specimens for all experimental conditions, and the slope was more accentuated for OXDC. Differences among shades and distances from LCU tip were evident only beyond 1.5-2.0 mm of depth. In conclusion, both composite shade and distance from LCU tip might affect the light-transmission and depth of polymerization, while the effect of last was more pronounced.

“…No intuito de rea liza r uma restauração direta posterior satisfatória, além da utilização de materiais restauradores e adesivos de alta performance [4,10], é necessário o domínio das técnicas de preparo e escultura, bem como o conhecimento das características anatômicas de cada grupo dentário [6,18,22]. As características das superfícies oclusais dos elementos dentários posteriores são normalmente mais facilmente reproduzidas, uma vez que há maior acesso visual e melhor compreensão dos aspectos morfológicos dessa face por parte do operador.…”

Apesar dos permanentes avanços no desenvolvimento de materiais e técnicas restauradoras, restaurações de cavidades classe II ainda são um desafio para o profissional. Objetivo: Relatar um caso clínico de restauração direta classe II com o uso de pontas ultrassônicas em aparelho piezoelétrico e de sistema de matriz seccionada. Relato de caso: Paciente do sexo feminino, 56 anos, encontrava-se com queixa relacionada a sensibilidade no elemento primeiro molar superior direito. Após análises clínica e radiográfica, optou-se por substituição de restauração prévia em amálgama por uma restauração meso-ocluso-distal em resina composta. Após remoção do amálgama, a regularização da cavidade foi realizada por pontas ultrassônicas em aparelho piezoelétrico. A conformação das paredes proximais ocorreu mediante uso de matriz metálica seccionada em conjunto com cunha de madeira e anel de fixação. A restauração foi feita seguindo a técnica incremental, com resinas compostas micro-híbridas, em associação com resina composta bulk fill flow. Na sequência, a restauração passou por etapas de ajustes oclusais, acabamento e polimento. Resultados: Após a conclusão do caso, notaram-se morfologia oclusal e conformação do ponto contato satisfatórias. Conclusão: As técnicas de preparo e escultura utilizadas neste caso clínico promoveram um resultado adequado, tanto do ponto vista estético como funcional.

“…The results of this shrinkage have been well documented, with a clinical problem being the development of physical stresses at the restoration interface [14,20] and the type of composite affects the retention of composite restorations in dental cavities [21]. This stress may also occur between the orthodontic attachment and tooth enamel.…”
