Introdução: O compómero Twinky Star® da VOCO® tem sido amplamente
utilizado em odontopediatria devido à sua eficácia na restauração de dentes
decíduos. A avaliação da rugosidade de superfície deste compósito é importante
para garantir a qualidade e durabilidade das restaurações em pacientes
pediátricos.
Objetivos: O objetivo desta tese é determinar a rugosidade de superfície de
cada uma das 8 cores do kit da Twinky Star® da VOCO® sujeitas diferentes
formas de polimento.
Material e métodos: Para este estudo foram usadas 56 cápsulas de cada cor
de 0,25 g do Twinky Star® da VOCO® (7 x 8). As amostras foram divididas em 3
grupos de polimento: grupo A – polimento circular (3 x 8); grupo B – polimento
linear (3 x 8); grupo C – sem polimento (1 x 8). Foi avaliada a rugosidade de
superfície por auxílio de um rugosímetro e realizada a análise estatística com um
nível de significância de 0,05.
Resultados: Não pode ser realizado o modelo ANOVA fatorial envolvendo a
análise de rugosidade entre as variáveis cor, formas de polimento e interação
entre a cor e formas de polimento. Foi realizada a análise estatística por formas
de polimento. O grupo A apresenta menores valores de rugosidade média. O
grupo B apresenta maiores valores de rugosidade média do que o grupo A e
menores valores de rugosidade média do que o C. O grupo C apresenta maiores
valores de rugosidade média. Quanto às cores, no grupo A, o Blue, o Berry e o
Green obtiveram valores de rugosidade médio mais baixos. Enquanto o Lemon
obteve os maiores valores de rugosidade média. No grupo B, o Lemon obteve
os valores de rugosidade média mais baixos enquanto o Silver obteve os valores
de rugosidade média mais altos. No grupo C, o Orange obteve os valores de
rugosidade média mais baixos enquanto o Green obteve os valores de
rugosidade média mais altos.
Conclusão: A escolha da cor do compómero Twinky Star® a ser utilizado numa
restauração pediátrica não tem tanta importância quanto a forma como este é
polido.
Introduction: The Twinky Star® compomer by VOCO® has been widely used in pediatric dentistry due to its effectiveness in restoring deciduous teeth. The evaluation of the surface roughness of this composite is important to ensure the quality and durability of restorations in pediatric patients. Objectives: The objective of this thesis is to determine the surface roughness of each of the 8 colors in the Twinky Star® kit by VOCO®, subjected to different polishing methods. Materials and methods: For this study, 56 capsules of each color of 0.25 g of Twinky Star® by VOCO® (7 x 8) were used. The samples were divided into 3 polishing groups: group A circular polishing (3 x 8); group B linear polishing (3 x 8); group C no polishing (1 x 8). Surface roughness was evaluated using a profilometer, and statistical analysis was performed with a significance level of 0.05. Results: For the analysis of surface roughness, a factorial ANOVA model considering the variables of color, polishing methods, and the interaction between color and polishing methods could not be performed. Statistical analysis was carried out based on the polishing methods alone. Group A exhibited lower average roughness values compared to the other groups. Group B showed higher average roughness values than Group A but lower values compared to Group C. Group C had the highest average roughness values. Regarding color, within Group A, the Blue, Berry, and Green colors had lower average roughness values, while the Lemon color had the highest average roughness value. In Group B, the Lemon color had the lowest average roughness values, while the Silver color had the highest average roughness values. In Group C, the Orange color had the lowest average roughness values, while the Green color had the highest average roughness values. Conclusion: The choice of color for the Twinky Star® compomer used in a pediatric restoration is not as crucial as the way it is polished.
