“…Eight papers used seven modeling liquids for restorative purposes, with Composite Wetting Resin (Ultradent, South Jordan, UT, USA), Modeling Liquid (GC Corp., Tokyo, Japan), and Bisco Modeling Resin (Bisco, Schaumburg, IL, USA) being the ones most investigated [ 14 , 15 , 16 , 19 , 25 , 26 , 27 , 28 ].…”

“…According to the tests performed, lubricants were applied to three different modalities: (1) between two increments for tensile studies ( n = 4) [ 14 , 19 , 25 , 29 ]; (2) between three to four layers ( n = 6) for color stability analysis, monomer elution, and water uptake studies [ 10 , 13 , 21 , 22 , 28 , 30 ]; (3) on the top of the outer composite layer ( n = 7) to evaluate surface hardness, roughness, color stability, and degree of conversion [ 15 , 16 , 20 , 23 , 24 , 26 , 28 ]. Five out of the seventeen papers focused on bond strength [ 10 , 14 , 19 , 29 , 30 ].…”

“…Basically, MLs are unfilled resins comprised of methacrylates such as urethane dimethacrylate (UDMA), bisphenol A-glycidyl methacrylate (Bis-GMA), and triethylene glycol dimethacrylate (TEGDMA). MLs are mainly composed of hydrophobic non-solvated resins with scarce or no organic fillers, eventually not influencing the composite’s structure [ 16 ]. Even though MLs share the same methacrylate derivatives with the organic matrix of RBCs, chemo-mechanical alterations have been observed in the composite restorative materials after being modeled with the instrument lubricated with the ML.…”

Several lubricant materials can be used to model resin-based composites (RBCs) during restorative procedures. Clinically, instruments or brushes are wet with bonding agents (BAs) or modeling liquids (MLs) for sculpturing purposes. However, a knowledge gap exists on their effects on the mechanical properties of RBCs, requiring greater insight. Five databases were searched, including 295 in vitro studies on the use of lubricant materials for modeling RBCs during restorative procedures. Only articles in the English language were included, with no limits on the publication date. The last piece of research was dated 24 March 2022. In total, 16 studies were included in the review process, together with a paper retrieved after screening references. A total of 17 BAs and 7 MLs were investigated. Tensile (n = 5), flexural strength (n = 2), water sorption (n = 2), color stability (n = 8) and translucency (n = 3), micro-hardness (n = 4), roughness (n = 3), degree of conversion (n = 3), and monomer elution (n = 2) tests were carried out. In general, a maximum of 24 h of artificial storage was performed (n = 13), while four papers tested the specimens immediately. The present review identifies the possibilities and limitations of modeling lubricants used during restorative procedures on the mechanical, surface, and optical properties of RBCs. Clinicians should be aware that sculpturing RBCs with modeling resins might influence the composite surface properties in a way that is material-dependent.

Resin composites are one of the most commonly used materials in restorative dentistry. To improve their handling and facilitate restoration sculpting, clinicians began to lubricate modeling instruments with various substances like alcohol, unfilled resins, or even bonding agents. Although the technique is commonly present in daily clinical practice, it has not been precisely described in the literature and both application methods and lubricating materials vary across the available studies. This study aims to summarize the currently available knowledge about influence of instrument lubrication on properties of dental composites. Literature selection was conducted within MEDLINE, SCOPUS, and EBSCO databases. Instrument lubrication seems not to be indifferent for composite mechanical and optical properties. Moreover, various lubricants can differently affect the composite material, so the choice of lubricating agent should be deliberate and cautious. Available in vitro studies suggest possible incorporation of lubricant into the composite structure. Unfilled resins based on bisphenol A-glycidyl methacrylate (Bis-GMA) seem to be the best choice for the lubricant, as bonding agents containing hydrophilic molecules and alcohols carry a bigger risk of altering the composite properties. Further research is necessary to evaluate lubricants' influence in clinical practice conditions.

“…O modelador de resinas vem sendo empregado para melhorar o manuseio clínico das resinas compostas, já que grande parte desses compósitos presentes no mercado odontológico atual possuem aderência às espátulas de inserção, o que dificulta a confecção da anatomia dental tão crucial ao procedimento restaurador, podendo gerar falhas no interior da restauração. (Bayraktar, 2021). Formações de bolhas ou defeitos coesivos da resina estão entre as principais consequências e podem afetar diretamente as propriedades ópticas da restauração, sobretudo a translucidez e a estabilidade de cor (Munchow, 2016).…”

Introdução: Diastemas estão entre as principais queixas estéticas dos pacientes e podem ser classificados como espaços extras, localizados entre dois dentes ou mais, causados por diferenças de tamanhos dentais, ausência dos mesmos, desproporção dos dentes no arco superior com inferior, hábitos deletérios e vários outros fatores. A busca por tratamentos conservadores possibilitou o desenvolvimento de resinas cada vez mais aprimoradas, que visam o estabelecimento de restaurações com estética satisfatória em um menor tempo de trabalho, sem necessidade de maiores desgastes, preservando a estrutura dental. Objetivos: Relatar um caso clínico onde foi restabelecida a estética em diastemas anteriores com o uso de resinas diretas e agentes umectantes, evitando maiores desgastes, devolvendo função e autoestima para o paciente. Descrição do caso: Foi realizado protocolo fotográfico, clareamento de consultório e caseiro, seguido de enceramento diagnóstico, com montagem em articulador, verificação de guias, confecção de matriz de silicone para obter a incisal, seguida do fechamento dos diastemas com resinas diretas e uma fina camada superficial com agente umectante. Considerações Finais: A resina composta se mostrou uma excelente alternativa quando utilizada de maneira correta por um profissional capacitado, que compreenda os princípios estéticos e psicológicos de seu paciente. A utilização de agente umectante associado a resina composta proporcionou o sucesso do tratamento restaurador facilitando manipulação da resina e consequentemente a anatomia, superando as expectativas do paciente, devolvendo ao mesmo a estética de seus dentes, elevando, assim, sua autoestima.
