Resumo: | The methods of caries removal have been the subject of many studies over the last years. At present, methods involving the least tissue invasion have been outstanding in the field of surgical-restorative treatment. In this context, the Carisolv™ system has appeared as a less traumatic and less invasive approach, particularly in pedodontics. Thus, the objective of the present study was to carry out a comparative analysis of the dentinal structure of primary molars before and after the removal of carious tissue by mechanical (low speed drills and conventional dentinal curettes) and chemomechanical (Carisolv™ kit) procedures based on quantitative culture for cariogenic bacteria to determine the number of bacteria present in the carious dentine after both treatments. Sixty primary molars from children ranging in age from 4 to 8 years, with active occlusal caries in dentine, were divided into two groups (A and B) of 30 teeth each, with group A having been treated by the chemomechanical technique and group B by the mechanical technique. Dentin samples were placed in glass vials containing 1 mL thioglycolate broth and submitted to culture to determine the number of S. mutans and Lactobacillus per mg of decayed dentine. The results did not reveal significant differences between the two methods of caries removal; however, the chemomechanical method was more efficient in completely eliminating S. mutans (p=0.02). In summary, the present results confirm previous studies showing that the two methods are comparable in reducing Lactobacillus, but Carisolv™ is more effective in the elimination of S. mutans. |

Os métodos de remoção de cárie têm sido objeto de muitos estudos nos últimos anos. Atualmente, aqueles que determinam mínima invasão tecidual têm se sobressaído no campo do tratamento cirúrgico-restaurador. Neste contexto, surgiu o sistema Carisolv™ como uma abordagem menos traumática, com destaque na odontopediatria e menos invasiva. Desta forma, este estudo teve como objetivo analisar comparativamente a estrutura dentinária de molares decíduos antes e após a remoção do tecido cariado pelos métodos mecânico (brocas de baixa rotação e curetas dentinárias convencionais) e químico-mecânico (Kit Carisolv™), através de exame microbiológico quantitativo, verificando-se o número de bactérias/mg presentes na dentina cariada após cada tratamento. Foram utilizados 60 molares decíduos de crianças na faixa etária de 4 a 8 anos de idade que apresentavam cárie oclusal ativa em dentina, os quais foram divididos em dois grupos (A e B) de 30 dentes cada, onde o grupo A foi tratado com a técnica químico-mecânica e o grupo B foi tratado com a técnica mecânica. As amostras de dentina foram coletadas e depositadas em frascos de vidro contendo 1mL de caldo Tioglicolato e pérolas de vidro. Em seguida, foram imediatamente encaminhadas para análise microbiológica para que fossem determinadas as concentrações de S. mutans e Lactobacillus por mg de dentina cariada. Os resultados não revelaram diferenças significantes na comparação dos dois métodos de remoção de cárie; contudo, foi verificado que o método químico-mecânico era mais eficiente na eliminação total de S. mutans (p=0,02). Em síntese, os nossos resultados confirmam alguns estudos prévios em que os métodos são comparáveis na redução de Lactobacillus, mas o Carisolv™ é mais eficaz na eliminação de S. mutans.
