Influencing factors of root resorption in orthodontic patients
Objective:To analyze influencing factors of root resorption in orthodontic patients.Methods:A cross-sectional study was conducted on 78 patients who underwent orthodontics treatment in this hospital from May 2020 to August 2022.The clinical data of these patients were collected.The levels of gingival crevicular fluid indexes were detected and the root resorption was determined.These patients were divided into resorption group and non-resorption group according to whether root resorption occurred.Logistic regression was used to analyze the influencing factors of root resorption in these orthodontic patients.Results:There were 35 cases of root resorption in the 78 orthodontic patients with an incidence of 44.87%(35/78).There were no significant differences in gender,age,orthodontic treatment course and orthodontic tooth position between the two groups(P>0.05).The proportions of the patients with the frequency of brushing teeth<2 times/week,the frequency of taking sweet foods>3 times/week,the frequency of drinking carbonated drinks>3 times/week,no fluoride toothpaste,the vertical position of teeth as low,orthodontic extraction,non-dental overall movement,the persistent force provided by the appliance,proximal and distal partitions of the orthodontic site as 2-4 areas,matrix metalloproteinase-9(MMP-9)level>5.64 ng/mL,and interleukin-17(IL-17)level>29.99 pg/mL in the resorption group were higher than those in the non-resorption group,and the differences were statistically significant.Logistic regression analysis showed that orthodontic extraction,non-dental overall movement,MMP-9 level>5.64 ng/mL,IL-17 level>29.99 pg/mL were all risk factors for root resorption in the orthodontic patients(OR>1,P<0.05).Conclusions:Orthodontic extraction,non-dental overall movement,MMP-9 level>5.64 ng/mL,IL-17 level>29.99 pg/mL are the risk factors for root resorption in the orthodontic patients
