Resumo
Na Odontologia atualmente têm-se enfatizado a prática de técnicas menos invasivas para a remoção de tecido cariado, que preservem ao máximo as estruturas dentárias. O interesse clínico e laboratorial por essas técnicas tem aumentado em função da realização de estudos que comprovaram a eficácia da remoção manual de dentina infectada, bem como as vantagens da técnica conservadora e indolor. O objetivo desse estudo foi analisar e comparar os tratamentos mecânico manual (ART convencional) e químico-mecânicos (CarisolvTM e Papa-cárie®) na remoção de dentina cariada, por meio da contagem de Streptococcus mutans e Lactobacillus e avaliação clínica de sintomatologia dolorosa durante o procedimento restaurador. Para a realização do presente estudo foram selecionadas 32 crianças, de ambos os sexos, com idade entre 6 e 10 anos, que apresentavam no mínimo dois molares decíduos, com exposição de dentina cariada. As crianças foram divididas aleatoriamente em dois grupos homogêneos, totalizando 64 dentes. O grupo I foi submetido à remoção mecânica em um elemento dental e em outro dente a químico-mecânica com o uso de Carisolv e o grupo II, a remoção mecânica e a químico-mecânica com o uso do Papacárie®. Durante a realização dos tratamentos foram feitas coletas de dentina, antes e após a remoção de tecido cariado e aplicação de um questionário para a avaliação clínica. Posteriormente, foram realizadas diluições seriadas e cultivo das amostras em meios específicos, Mitis salivarius bacitracina sacarose para a contagem de Streptococcus mutans e Rogosa, para contagem de Lactobacillus ssp. Após o período de incubação, a 37º C e 72 horas, foi realizada a contagem de Unidades Formadoras de Colônias (UFC) e obtidos os valores médios do número de bactérias.
In Dentistry, nowadays, it has been emphasizing the practice of techniques less invasive for the removal of decayed tissue that preserve the maximum the dental structure. The clinical laboratorial interest for those techniques have been increasing due to studies that proved the effectiveness of the manual removal of infected dentine, as well as the advantages of the conservative and painless technique. The objective of this study was to analyze and to compare the manual mechanic (conventional ART) and chemical-mechanic (Carisolv and Papa-carie®) treatments in the removal of decayed dentine, through the score of Streptococcus mutans and Lactobacillus and clinical evaluation of pain symptoms during the restorative procedure. For the performance of the present study 32 children were selected, of both genders, with age between 6 and 10 years that presented at least two deciduous molars, with exhibition of decayed dentine. The children were divided at random in two groups, summing 64 teeth. The group I was submitted to the mechanical and chemical-mechanical removal with the use of Carisolv and the group II, mechanical and chemical-mechanic removal with Papacárie®. During the performance of the treatments, dentine sample were collected, before and after the removal of decayed tissue and application of a questionnaire for the clinical evaluation. Later, it was carried out seriate dilutions and cultivation of the samples in Mitis- salivarius bacitracin sucrose for the score of Streptococcus mutans and Rogosa, for score of Lactobacillus ssp. After the incubation period, at 37° C and 72 hours, it was carried out the score of the ColonY Forming Units (CFU) and obtained the mean values of the bacteria number.
