The aim of this study was to compare the effectiveness of high speed (HS) and air abrasion (AA) instruments on groups of teeth (deciduous, permanent, bovine), in terms of preparation time, topography and presence of smear layer. Each group consisted of 5 teeth that had their buccal/lingual surfaces prepared by using either HS or AA. All procedures were standardized and timed. The teeth were then sectioned and prepared for evaluation of both the topography and the presence of smear layer by scanning electron microscopy. As regards preparation time, HS yielded preparations 1.5 times quicker than AA did on the three types of dental substrates (Wilcoxon test, p < 0.05). In both techniques (KruskalWallis Test, p < 0.05) the preparation time was influenced by the dental substrate, particularly in deciduous teeth (Mann-Whitney test with Bonferoni's correction, p < 0.017), which required a longer preparation time.In the descriptive analysis of the topography, no difference was found between the substrates. Nonetheless, the different instruments used determined distinctive topographies. Both techniques produced a smear layer (χ 2 McNemar, p > 0.05) in all substrates, but with different formations. In conclusion, the HS instrument was found to be more rapid than the AA. No difference was found between the three dental substrates as regards both the topography and the presence of smear layer. The differences found in the present study were only in relation to the effects of each instrument used.

“…13 However, it is very difficult to establish the time spent on preparing a cavity with either high speed or air abrasion instruments. In general, studies report that both preparation systems are fast and secure by evaluating the pre-fixation time 14,15 or analyzing the time/weight relationship.…”

“…The list of materials was set up considering the dental care performed by the dental team (operator and auxiliary), following the biosecurity principles and the currently recommended conservative restorative techniques based on scientific evidence [15][16][17] . The operative and restorative procedures were standardized as follows: specific diamond drills 20 were sterilized before use and changed after being used in 10 patients 21,22 ; no liner was used; absolute isolation was provided; use of condensation composite resin; an incremental placement technique was employed for the restorative materials; occlusal adjustment, finishing and polishing were performed with carbon paper and specific tips and sandpaper discs and strips 16,17 . The materials were classified into 7 different groups and for each one were established the following standardization criteria 23 : -Group 1: -Group 1: -Group 1: -Group 1: -Group 1: Materials used for the maintenance and cleaning of equipment.…”

Aim: To assess the total cost of direct and indirect materials used in Class III, IV and V composite resin direct restorations. Methods: The calculation of costs was based on the method of variable costing system. A list of the materials was obtained by a panel of experts and based on the excellence standards established in the literature for dental team treatment. The cost considered for each material was obtained from an average of the costs found in the regional supplier market (US$1.0=R$2.12). The repetitions were obtained from Class III, IV and V cavities in artificial premanufactured teeth. The cavities were classified as shallow, medium and deep. The materials were quantified for each type of preparation. Seven brands of composite resins were used and weighed on a precision scale after their insertion in each cavity. The data were analyzed by descriptive statistics and non-parametric Friedman's test (α=0.05).

Análise de custo de materiais utilizados em restaurações dentárias em resina composta ResumoIntrodução: As resinas compostas são materiais usualmente utilizados em restaurações dentárias diretas de dentes posteriores. O custo dos materiais faz parte do cálculo do valor dos honorários odontológicos. Objetivo: O objetivo deste trabalho foi determinar e analisar o valor total do custo dos materiais utilizados para a confecção de restaurações dentárias diretas de dentes posteriores em resina composta. Material e método: O cálculo dos custos foi baseado no método de sistema de custeio variável. A lista dos materiais foi obtida por meio de consulta a uma banca de juízes e baseada nos padrões de excelência comprovados na literatura para atendimento em equipe. Os valores dos materiais foram obtidos de uma média dos valores consultados no mercado fornecedor. As repetições foram obtidas de preparos cavitários Classes I e II em dentes pré-molares e molares artificiais pré-fabricados. Os materiais foram quantificados para cada tipo de preparo. As resinas compostas utilizadas foram pesadas em balança de precisão após a sua inserção em cada tipo de preparo. Os dados foram avaliados por estatística descritiva e pelos testes de Mann-Whitney e Kruskal-Wallis. Resultado: O custo encontrado para restauração de Classe I foi de R$17,56 e, para a de Classe II, de R$17,73. Não houve diferença estatística no custo entre os tipos de preparo e de dentes, sendo a média total de R$17,65. Conclusão: Os valores encontrados podem ser utilizados no cálculo do valor final do procedimento restaurador, auxiliando na gestão de serviços odontológicos públicos ou privados.Descritores: Odontologia; custos e análise de custo; materiais dentários; resinas compostas.
