# Exploring Dentists' Preferences in Selecting Adhesive Systems: A Survey Analysis
## 3 Results  
In total, 83.57% of the dentists responded to the questionnaire, from which 534 dentists (91.28%) provided valid responses to the survey. Table 1 and Figure 1 demonstrate that etch-and-rinse (ER) techniques are the preferred choice among dentists, regardless of their graduation year. The most frequently used (Tables 2 and 3) adhesive systems reported by survey participants were as follows: from the ER type (10.32%): EE-Bond (Tokuyama\({}^{\text{\text{\textregistered}}}\), Osaka, Japan), Optibond \({}^{\text{\text{\textregistered}}}\) FL (Kerr Dental, Orange, CA, USA), and Optibond\({}^{\text{\text{\textregistered}}}\) Solo Plus (Kerr Dental, Orange, CA, USA); from the SE type (32.36%): Clearfill\({}^{\text{\textregistered}}\) Bond (Kuraray Noritake Dental, Tokyo, Japan), Evertic\({}^{\text{\textregistered}}\) Bond (Ivocalar Vivadent AG, Schaan, Liechtenstein), G-aenial Bond\({}^{\text{\text{\textregistered}}}\) (GC Corp., Tokyo, Japan), and G-Bond\({}^{\text{\text{\textregistered}}}\) (GC Corp., Tokyo, Japan); and from the universal type (33.37%): All Bond Universal\({}^{\text{\textregistered}}\) (BISCO, Schaumburg, IL, USA), Futura \begin{table}

Table 1: ER or SE techniques used per graduation year. Bond\({}^{\text{\textcircled{R}}}\) (Voco, Cuxhaven, Germany), Scotch Bond\({}^{\text{TM}}\) Universal Plus (3 MT\({}^{\text{TM}}\) ESPE, St. Paul, MN, USA), and Single bond universal (3 MT\({}^{\text{TM}}\) ESPE, St. Paul, MN, USA). In addition to the 11 adhesive systems most used by dentists, the respondents reported using other adhesive systems. These systems are highly diverse and were categorized as miscellaneous (Figure 2). The eleven systems most preferred by respondents were grouped for analysis (Table 4, Figure 3). The most frequently encountered difficulties are summarized in Table 5, which indicates that there was no statistically significant difference between the categories of difficulties encountered with respect to the dependent variable, graduation year, \(p\) = 0.156, when the Kruskal-Wallis test was performed. Figure 4 illustrates these findings. \begin{table}
