Comparison between aluminum chloride and tetryzoline hydrochloride for control of vertical gingival displacement and crevicular fluid

Abstract

ResumoIntrodução: A utilização de fio de afastamento gengival com uma substância de afastamento gengival é um procedimento comum para se realizar uma moldagem com qualidade do término cervical em dentes com finalidade protética. Objetivo: Avaliar se o método mecânico-químico com cloridrato de tetrizolina a 0,05% ou cloreto de alumínio a 25% são capazes de reduzir o fluido crevicular e afastar o tecido gengival verticalmente em uma quantidade maior, estatisticamente significante, em comparação com o método mecânico de afastamento (sem substâncias químicas). Material e método: Dez pacientes foram selecionados, e os fios Ultrapak n° 000 e 1 foram posicionamos de maneira randomizada nos dentes 13, 21 e 23. Grupo I: fio sem substância química; Grupo II: fio impregnado com cloridrato de tetrizolina; Grupo III: fio impregnado com cloreto de alumínio. Utilizando modelos de gesso, foram capturadas trinta imagens com uma câmera acoplada a uma lupa, para análise do grau de afastamento. O fluxo crevicular foi quantificado através de uma balança de alta precisão, a partir de tiras de papel absorvente personalizadas para cada dente que recebeu afastamento gengival. Resultado: Não houve diferença estatística entre os três grupos quanto a quantidade de afastamento gengival vertical (Anova, p=0,26). Quanto a redução de fluido crevicular, não houve diferença entre os grupos teste e controle (Wilcoxon e Friedman, p < 0,05). Conclusão: A utilização do cloridrato de tetrizolina ou cloreto de alumínio em fio de afastamento gengival não melhorou a quantidade de afastamento vertical da gengiva e não reduziu a quantidade de fluido crevicular.Descritores: Retração gengival; líquido do sulco gengival; sulco gengival. AbstractIntroduction: The use of a gingival displacement cord with a gingival displacement substance is a common procedure for taking a quality impression of the cervical terminal in teeth for prosthetic purposes. Objective: To evaluate whether the mechanical-chemical method with 0.05% tetryzoline hydrochloride or 25% aluminum chloride is capable of reducing crevicular fluid, and displacing a statistically significant larger quantity of gingival tissue vertically, compared with the mechanical method (without chemical substances). Material and method: Ten patients were selected, and then No. 000 and 1 Ultrapak cords were randomly positioned on teeth 13, 21 and 23. Group I -cord with no chemical substance; Group II -cords impregnated with tetryzoline hydrochloride and Group III -cords impregnated with aluminum chloride. Using dental stone models, thirty images were captured with a camera coupled to a loupe to analyze the degree of gingival displacement. Crevicular fluid was quantified using a high-precision scale and individualized strips of absorbent paper for each tooth on which gingival displacement was performed. Result: There was no statistical difference between the three groups relative to the amount of vertical gingival displacement (Anova, p=0.26). As regards reduction in crevicular fluid, there was no difference betwe...
