INTRODUÇÃO: Os ionómeros de vidro são muito usados na
Odontopediatria, principalmente em jovens menos colaborantes, devida à sua
versatilidade e facilidade de utilização. O consumo prolongado de medicação
líquida pediátrica e a falta de higiene oral podem deteriorar as estruturas
dentárias e as restaurações.
OBJETIVO: Determinar e comparar, laboratorialmente, os valores da
rugosidade de superfície de 4 discos de ionómero de vidro, mergulhados em
diferentes soluções medicamentosos, ao longo de 21 dias.
MATERIAIS E MÉTODOS: Para este estudo foi usado um ionómero de
vidro convencional (Ketac®, 3M, ESPE). Foram produzidos 4 discos de IV a
partir de uma matriz cilíndricas (8 x 2 mm). Cada disco foi submerso durante 21
dias numa das seguintes medicações, Clamoxyl® 250mg/5ml, Ben-u-Ron®
40mg/m, Brufen sem açúcar® 40mg/ml e Brufen® 20 mg/ml. A rugosidade
superficial foi avaliada por profilometria e foi realizada a análise estatística, com
um nível de significância de 0,05.
RESULTADOS: Foram realizados os testes de Kruskal-Wallis e ANOVA
para avaliar as variáveis, tempo de exposição e medicação líquida pediátrica.
Fizemos a comparação do disco ao longo do tempo de exposição. Todos os
discos apresentaram alterações de rugosidade. O disco mergulhado em
Clamoxyl® 250mg/5ml não apresentou relevância estatística p>0.05. O disco
mergulhado em Ben-u-Ron® 40mg/m apresentou alterações com relevância
estatística a partir dos 7 dias. Os discos mergulhados em Brufen sem açúcar®
40mg/ml e Brufen® 20 mg/ml apresentarem resultados com relevância
estatística a partir de 14 dias.
CONCLUSÃO: Devemos ter em conta se a criança faz uso constante de
medicamentos líquidos pediátricos, para determinar qual a melhor escolha de
material restaurador, pois alguns destes podem causar degradação da
superfície do material restaurados. Mais estudos devem ser realizados com
diferentes materiais restauradores para permitir ao Médico-Dentista efetuar
uma escolha de material adequada para este tipo de situações.
INTRODUCTION: Glass ionomers are widely used in Pediatric Dentistry, especially in uncooperative young patients, due to their versatility and ease of use. Prolonged consumption of liquid pediatric medication and lack of oral hygiene can deteriorate dental structures and restorations. OBJECTIVE: To determine and compare the surface roughness values of 4 glass ionomer discs immersed in different medication solutions over a period of 21 days, in a laboratory setting. MATERIALS AND METHODS: A conventional glass ionomer (Ketac®, 3M, ESPE) was used for this study. Four glass ionomer discs were produced from cylindrical matrices (8 x 2 mm). Each disc was immersed for 21 days in one of the following medications: Clamoxyl® 250mg/5ml, Ben-u-Ron® 40mg/m, Sugarfree Brufen® 40mg/ml, and Brufen® 20 mg/ml. Surface roughness was evaluated using profilometry, and statistical analysis was performed with a significance level of 0.05. RESULTS: Kruskal-Wallis and ANOVA tests were performed to assess the variables of exposure time and pediatric liquid medication. The comparison of the discs over time of exposure was conducted. All discs showed changes in roughness. The disc immersed in Clamoxyl® 250mg/5ml did not show statistical significance (p>0.05). The disc immersed in Ben-u-Ron® 40mg/m showed statistically significant changes after 7 days. The discs immersed in Sugar-free Brufen® 40mg/ml and Brufen® 20 mg/ml showed statistically significant results after 14 days. CONCLUSION: It is important to consider if the child frequently uses liquid pediatric medications to determine the best choice of restorative material, as some of these medications can cause degradation of the restorative material surface. Further studies should be conducted using different restorative materials to enable dentists to make an appropriate material choice for these situations.
