“…In several in vitro studies, multi-step aluminum-oxide discs exhibited the smoothest surfaces [13][14][15][16] ; however, due to their geometry, the anatomically contoured surfaces of composite restorations are difficult to polish 12) . In contrast, oneand two-step polishing systems that use elastomeric or rubberized polishers in various shapes, sizes and dimensions come into direct contact with the restoration surface and complement the access limitations of the aluminum-oxide discs.…”

The purpose of this study was to investigate surface roughness (Ra) and morphology of supra-nanofilled [Estelite Omega (EO), Estelite ∑ Quick (EQ)], micro-hybrid [Esthet.X HD (EHD), G-aenial (GAE)] and nano-hybrid [Clearfil Majesty Posterior (CMP), Charisma Diamond (CD), Beautifil II (BII)] composites polished with two-step polishing systems [Enhance/PoGo (EP); Venus Supra (VS)]. Composite discs, 30 of each type, were prepared. Each composite group was divided into three subgroups: Mylar (control), EP and VS. Ra was evaluated with profilometer. In each composite group, the control had the lowest Ra. With both polishing systems, EO and EQ had significantly the lowest Ra, whereas CMP and BII had the highest. Except for GAE, CD and BII, the differences in Ra between EP and VS in each composite group were significant, showing smoother surfaces for EP. Supra-nanofilled composites created smoother surfaces than nano-hybrids, and their performance was similar or slightly better than that of micro-hybrids.

“…Increasing the particle size of the resin by decreasing the proportion of organic filler matrix can decrease the change in color (11). Hybrid composite resins were used in this study because they have good mechanical resistance and good esthetics (12,13).…”

Aim: Diastemas can be treated using periodontal, surgical, orthodontic, or prosthetic procedures. Composite laminate veneers can be applied to reduce or eliminate diastemas and represent a good aesthetic non-invasive alternative for these patients. This study presents the treatment results of 10 patients with diastemas between the anterior teeth of the maxilla and mandible with composite veneers. Methodology: Ten patients with diastemas between the anterior maxillary and mandibular teeth complaining of esthetic problems were treated at the Department of Operative Dentistry, University of Dicle. The periodontal health of the patients was acceptable and no caries were detected. Patients were informed of the treatment choices and composite resin veneers were selected as the better approach for each case. The presence of a diastema causes esthetic problems, especially in adolescents. Prosthetic and conservative methods are usually used to treat diastemas because these approaches are minimally invasive. The direct laminate technique has the advantages of low cost, treatment reversibility, and easy repair of the restoration intraorally. The direct composite laminate technique has become more effective because of improvements in adhesive dentistry. Conclusion: This study describes a direct composite laminate technique for the restoration of the anterior teeth of 10 patients with diastemas. These restorations were conservative and provide an inexpensive, one-visit aesthetic treatment for anterior teeth.

Foram avaliadas diferentes formas de glazeamento da superfície de porcelana quanto à resistência ao cisalhamento de bráquetes metálicos colados com diferentes cimentos. Quarenta e dois corpos de prova de metalocerâmica foram confeccionados (2 controles) e divididos em quatro grupos de acordo com o tipo de glazeamento, com camada extra de glaze (G) ou auto-glazeados (AG), e o cimento utilizado, resina fotopolimerizável (r) ou ionômero de vidro resinosos (i), formando os seguintes grupos: Gr, Gi, AGr e AGi com 10 corpos de prova cada grupo. Todas as superfícies dos corpos de prova receberam tratamento com ácido fosfórico 35% por 30 s seguidos de uma camada de silano. Quarenta bráquetes metálicos foram colados. Os corpos de prova foram submetidos a termociclagem e ao teste de resistência ao cisalhamento com uma máquina universal de ensaios mecânicos. Uma amostra de cada grupo após descolagem, remoção da resina e polimento, foi avaliado em microscópio eletrônico de varredura. O índice de fratura coesiva da porcelana foi também avaliado. Os resultados mostram valores acima da média aceitável na literatura para todos os grupos, sendo que o grupo AGr apresentou valor menor (10,38 MPa) e estatisticamente significativo em relação aos demais. A análise no microscópio eletrônico de varredura mostrou que as superfícies, após polimento, não readquirem as características de antes da colagem, apesar de se apresentarem aceitáveis clinicamente. Houve fratura da porcelana em todos os grupos. Conclui-se que é possível se conseguir colagem adequada de bráquetes metálicos em superfícies metalocerâmicas auto-glazeadas e com camada extra de glaze, preservando-o, não necessitando reconhecer previamente a forma de glazeamento.
