Desislava Makakova

Abstract: This study aimed to analyze dentists' preferences regarding the use of retraction cords and their placement techniques in clinical practice when fabricating fixed restorations. A survey comprising 2 demographics, and 8 targeted questions focused on the retraction methods and devices used, with data analyzed using SPSS (version 23) through descriptive and non-parametric analysis. Statistical significance was determined using ?? (chi-square) and Mann-Whitney U tests with a significance level of 0.05. The results showed that 57.1% of participants preferred aluminum chloride (Al?Cl?)-impregnated retraction cords, with a statistically significant difference (P<0.001, U=5.673). Additionally, 71.7% favored the single cord technique (P<0.001, U=6.788), primarily for its ease of use. The findings highlight a preference for Al?Cl? - impregnated cords due to their hemostatic efficiency, with the single cord technique preferred for its simplicity and less invasive nature. In contrast, the double cord technique is used in more complex cases.
