Chapter 588ResultsDescription of subjectsA total of 87 subjects participated in this study, including 52 women and 35 men, with an average age of 26.47 years (SD, 6.36 years). These participants were randomly allocated to the experimental group (iodine tampon) or control group (Monoject® syringe). A chi-square test showed that the distribution of men and women did not significantly differ between the two conditions (Table 1). An independent-samples t-test revealed that the average age was significantly higher in the experimental group compared to the control group. Correlation analysis (Pearson’s) for the age variable and the seven mean OHIP14 sum scores (repeated measurements of OHIP-14 over seven postoperative days) did not reveal statistically significant correlations; therefore, age was not included as a covariate in follow-up analyses.Table 2 presents a frequency table showing the Pell & Gregory classification for both groups [25]. The Mann-Whitney U test was used to analyze differences in impaction grade between the two conditions. The results showed that impaction grade did not significantly differ between the iodine tampon group and the Monoject® syringe group (U = 735.00, z = −1.91, p = 0.56).Table 1: Characteristics of examined groupsIodinetampon (N = 44)Monoject® syringe (N = 43)Difference testMen 17 18 χ2 = 0.94, df = 1, p = 0.76Women 27 25 36Average age (SD) 28.11 (7.27) 24.79 (4.80) T = −2.51, df = 74.73, p = 0.014Table 2: Frequency Pell & Gregory classification of impaction of examined groupsImpaction grade Iodinetampon (N = 44)Monoject®syringe (N = 43)Total2a 2 3 82b 5 5 103a 12 20 323b 22 15 373c 3 0 3Total 44 43 87
