“…In some clinical studies on posterior composites, rubber dam was used to isolate the teeth [21][22][23] , whereas Turkun 24) , Kohler et al 25) , and Pallesen and Qvist 26) opted for cotton rolls and saliva suction device. Raskin et al 27) , in a 10-year evaluation of posterior composites, did not observe significant differences between these two isolation methods.…”

The aim of this study was to assess the clinical performance of three direct composite resins and two indirect inlay systems in posterior teeth using the modified USPHS criteria. A total of 100 restorations were placed in the molars of 54 patients by one operator. All restorations were directly evaluated by two examiners at baseline, 6 months, and 12 months. Statistical analysis was conducted using McNemar chi-square test at a significance level of 5% (p<0.05). Recall rate was 100% at 6 and 12 months, and all the restorations evaluated (i.e., 100%) received Alpha rating for the criteria of retention and gingival adaptation. At 12 months for the surface texture criterion, 80% of Filtek Supreme XT received Alpha rating while it was 95% for Tetric EvoCeram and AELITE Aesthetic. For marginal discoloration, 85% of Tescera ATL and Filtek Supreme XT received Alpha rating while it was 95% for Tetric EvoCeram and AELITE Aesthetic. Further, none of the restorative systems received a Charlie rating for any of the criteria at all evaluation periods. In summary, all the restorations demonstrated clinically satisfactory performance with no significant differences detected among them.

“…6 Successful use of resin-composite in extensive posterior cavities is significantly affected by operative competence and diligence, with failure rates being greatest in the molar region. 5,9 Practice-based research studies and opinions report disappointingly low success rates for posterior composites. 5,7,8 There is a need for techniques and materials that will accommodate the variable demands of clinical practice whilst allowing successful use of posterior resin-composite in large cavity preparations.…”

A pilot investigation of operator variability during intra-oral light curing

et al. 2002

Objective To test the hypothesis that operator experience influences the efficacy of light curing in a typical posterior intra-oral location. To investigate whether short cure cycles affect performance. Design A cross-sectional single-centre study designed to assess the efficacy of experienced and inexperienced operators when undertaking simulated intra-oral curing. Setting An in vitro laboratory based investigation conducted in a dental school during 2001. Materials and methods A computer-based technique was used to monitor light intensity in a clinical simulation. Dentists and student operators were tested for their ability to cure a posterior restoration effectively. Relative light intensity was assessed against time for each operator and test run. Results Experienced (qualified) operators produced more effective and consistent cure results than less experienced undergraduate students. Operator performance was not affected by variations in irradiation time. Conclusions This cross-sectional pilot investigation demonstrates that operator experience is a factor in successful clinical photo-curing of posterior restorations. Stable and accurate light guide positioning are required throughout the entire irradiation cycle to optimise intra-oral cure of light-activated restorations. Further investigations are planned to assess the potential of this novel method of assessment for use as a routine teaching aid in clinical practice.Direct placement resin-based composites are increasingly being used as an alternative to dental amalgam for the restoration of cavities in posterior stress bearing situations. [1][2][3][4] Whilst the rate at which dentistry is entering the post amalgam-age varies according to country 1-4 the trend is set to continue as clinicians are increasingly being asked to satisfy the expectations of patients who seek safe, biocompatible and affordable tooth-coloured restorations. 3

ResumoAs restaurações diretas em resina composta são amplamente utilizadas pelos cirurgiões dentistas. As várias técnicas descritas na literatura enfatizam e ratificam a natureza conservadora e minimamente invasiva. Porém, quando há grande destruição coronária, envolvendo mais de dois terços da distância intercuspídea, ou até mesmo o comprometimento de uma ou mais cúspides, a melhor alternativa é realizar o procedimento restaurador de forma indireta (com restaurações do tipo inlay ou onlay). Estas restaurações podem ser confeccionadas, em laboratório, com materiais de metal, cerâmica ou resina. Este trabalho tem por objetivo relatar três casos clínicos que utilizaram a resina composta de forma indireta e termopolimerização adicional em autoclave. Para todos os casos foram realizados preenchimento morfológico da cavidade com resina composta microhíbrida, e preparo para onlay com pontas diamantadas em alta rotação. Para os três casos clínicos os moldes dos preparos dentais foram obtidos com elastômeros. Em dois casos os modelos foram obtidos com silicone polimerizado por adição monofásico de consistência regular. O terceiro caso o modelo foi obtido com gesso pedra tipo IV. As restaurações foram elaboradoras pela técnica incremental com resina composta microhíbrida sobre os modelos e finalizadas com termopolimerização adicional em autoclave por 20 minutos. A cimentação preconizada foi adesiva realizada com cimento resinoso autoadesivo sob isolamento absoluto e após isso ajuste oclusal. A finalização seguiu-se com acabamento e polimento. As técnicas restauradoras descritas constituem-se alternativa clínica viável do ponto de vista funcional e estético, possibilitando aos profissionais da área oferecer tratamento eficaz e de baixo custo.

The various techniques described in the literature emphasize and confirm the conservative and minimally invasive nature of these techniques. However, in the presence of extensive crown destruction involving more than two thirds of the intercuspal distance or even one or more cusps, the best alternative is to perform the procedure indirectly using inlay or onlay restorations. These restorations can be made in the laboratory with metal, ceramic or resin materials. The objective of the present paper is to report three clinical cases in which composite resin was used in an indirect manner with additional autoclave heath polymerization. Morphological filling of the cavity with microhybrid composite resin and preparation for onlay with high rotation diamond tips was performed in all three cases. The dental preparation models were botained with elastomers in all three cases. In two cases, the models were obtained with silicone polymerized by monophasic addition of regular consistency. In the third case, the model was obtained with type IV gypsum stone. The restorations were elaborated by the incremental technique with m...
