“…Mechanicochemical method of using a retraction cord impregnated or soaked in various chemicals is the most frequently used method 7 . Retraction cord mechanically displaces the gingival tissue and absorbs moisture contamination in the gingival sulcus, while the chemical agents control hemorrhage and shrink the gingival tissues.…”

Background & Objectives:Of the various gingival retraction systems available in the market, a cordless paste system is fairly new entrant into this field. This system promises to provide an easier method to obtain optimum retraction with excellent hemorrhage control. The present study was designed to clinically evaluate the efficacy of paste retraction system and medicated retraction cords on the basis of relative easy of working, hemorrhage control and amount of vertical gingival retraction. Methods: 40 subjects were selected requiring full veneer restoration where more than one abutment teeth were to be prepared. After the preparation of the abutment teeth flexible scales were used to measure the sulcus depth before retraction and after retraction. Medicated retraction cord technique was used on one abutment tooth and on the other abutment tooth paste retraction system was employed. Subjectively easy of placement and hemorrhage scores was assessed. Results: The mean time taken for paste retraction technique was 45.13 seconds and for medicated retraction cord technique was 105.4 seconds. In all the subjects paste retraction technique was relatively easier as compared with medicated retraction cord technique. Mean hemorrhage scores using paste retraction technique was 0.05 and using medicated retraction cord technique it was 1.70. Mean vertical gingival retraction using paste retraction technique was .36mm and using medicated retraction cord technique was 0.54mm Conclusion: Within the limitations of this study, paste retraction system requires reduced time for application, is easier to place, and provides excellent hemorrhage control in comparison to medicated retraction cord. However, medicated retraction cord provides increased amount of vertical retraction as compared to paste retraction technique.

“…Mevcut çalışmada, retraksiyon sonrası kanamanın en fazla geleneksel kord grubunda gözlenmesi önceki çalış-maları desteklemektedir 21,25 . Araştırmacılar; kanamasız, kuru bir sulkus elde edebilmek için mekanik ve kimyasal yöntemin kombine edilmesi gerektiğini vurgulamışlardır 3,8 . Mevcut çalışmada, %15' lik hemostatik ajan (AlCl 3 ) içeren iki grupta da kanama daha az görülmüştür.…”

“…Ölçü maddeleri yumuşak dokuları, sıvıları veya debrisi uzaklaştırmada yetersizdir ve tek başına uygun bir izolasyon sağlayamaz. Doğru bir model elde edebilmek için; debristen, sıvılardan uzak kuru bir alan yaratabilmenin yanında, ölçü alımında bitim çizgisinin açığa çıkarılması için yumuşak dokuların retrakte edilmesi gerekmektedir [1][2][3] . Restorasyon marjinleri supragingival konumlandırılmışsa rahatlıkla ideal bir ölçü alınabilir ve marjinal dişeti uyumu kolayca sağlanabilir.…”

“…However, many of these chemical agents promote side effects or disadvantages to the patient and / or impression material, such as: racemic epinephrine, one of the agents that cause systemic 1 alterations, as it increases the systolic blood pressure and pulse rate 6,7 ; ferric or ferrous salts may be corrosive and harmful to soft tissues, enamel and can stain the teeth 8 ; zinc chloride, a caustic and chagasic substance 5 , may cause damage to soft tissues and bone 8 ; and AlCl 3 , an anhydrous 5 astringent salt widely used in contemporary dentistry that has fewer adverse effects than other substances that can be used for this purpose 8 . In spite of this, AlCl 3 used at concentrations of over 10% 6 may cause tissue destruction and permanent gingival recession of 0.1 mm 9 .…”

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...
