Resumo

Resumo: Introdução: O hidróxido de cálcio é considerado uma medicação intracanal padrão ouro e diferentes substâncias podem ser empregadas como veículo para melhorar suas propriedades. O Aloe vera é um fitoterápico popularmente conhecido por babosa e que se destaca pela sua capacidade imunorreguladora, antimicrobiana, cicatrizante e pela biocompatibilidade celular.

Objetivo: Avaliar a dissociação iônica do hidróxido de cálcio, tendo o Aloe vera como veículo.

Material e método: O extrato de Aloe vera foi obtido diretamente da folha, submetido à filtração e armazenado em tubo Falcon estéril. Foram preparados dois grupos de medicação intracanal: o grupo controle, com hidróxido de cálcio e soro fisiológico, e o grupo experimental, com hidróxido de cálcio e Aloe vera como veículo.

Resultado: Não foi verificada uma diferença estatisticamente significativa entre as médias de liberação de cálcio dos grupos (p=0,944). Quando comparados os valores de forma pareada, considerando as diferentes avaliações ao longo do tempo, foi identificada uma diferença estatisticamente significativa (p=0,015) para o grupo experimental, de modo que os valores médios da liberação de cálcio foram superiores até o 21º dia do estudo.

Conclusão: O hidróxido de cálcio, quando associado ao Aloe vera, apresentou maior dissociação iônica que quando utilizado com água destilada. Tal resultado, associado às propriedades inerentes deste fitoterápico, sugerem que a pasta de hidróxido de cálcio e Aloe vera pode ser uma alternativa viável e promissora como medicação intracanal, e melhorar o reparo apical e periapical.

Abstract

Abstract: Introduction: Calcium hydroxide is considered an intracanal medication gold standard, and different substances can be employed as a vehicle to improve its properties. Aloe vera is a herbal remedy popularly known as babosa and is notable for its immunoregulatory, antimicrobial, healing and cellular biocompatibility.

Objective: To evaluate the ionic dissociation of calcium hydroxide, with the Aloe vera as vehicle.

Material and method: The extract of Aloe vera was obtained directly from the leaf, submitted to filtration and stored in a sterile falcon tube. Two groups of intracanal medication were prepared; the control group, with calcium hydroxide and saline; and the experimental group, with calcium hydroxide and Aloe vera as vehicle.

Result: There was no statistically significant difference between the means of calcium release from the groups (p = 0.944). When comparing the paired values, considering the different evaluations over time, a statistically significant difference (p = 0.015) was identified for the experimental group, so that mean values of calcium released were higher up to the 21st day of the study.

Conclusion: Calcium hydroxide, when associated with Aloe vera, presented higher ionic dissociation than when used with distilled water. This result, combined with the inherent properties of this herbal remedy, suggests that the paste of calcium hydroxide and Aloe vera can be a viable and promising alternative as intracanal medication and improve apical and periapical repair.
