## 3 Results  
Regardless of time, a statistically significant difference was obtained between the average values of the forces at the moment of tooth fracture according to the groups (\(p=0.009\)). While the average force in the group without CH dressing was 401.7, in the group with CH dressing, it was found to be 335.35. No statistically significant difference was observed between the average values of the forces according to time, regardless of group (\(p=0.387\)).

According to the interaction between group and time, no statistically significant difference was found between the average fracture resistance values (\(p\) = 0.229). The average force in groups that CH(\(-\))-1 min was 392.35, CH(\(-\))-3 min was 421.43, CH(\(-\))-5 min was 449.19, CH(\(-\))-10 min was 343.83, CH(+)-1 min was 299.14, CH(+)-3 min is 369.15, CH(+)-5 min was 319.38, CH(+)-10 min was 353.73, and the group of negative control was 623.96. The negative control group differed from other experimental groups (\(p\) < 0.001) (Tables 1 and 2). The average strength values of the groups are presented in Figure 4.
