Orthodontic treatment for children with traumatic tooth dislocation
Objective To analyze the effects of orthodontic treatment and manual reduction combined with arch splint fixation for children with traumatic tooth dislocation.Methods Sixty children with traumatic tooth dislocation treated at Department of Stomatology,Xi'an Third Hospital from October 2021 to October 2022 were selected for the randomized controlled trial,and were divided into a control group and an observation group by the random number table method,with 30 cases in each group.There were 17 boys and 13 girls in the control group;they were(10.12±2.12)years old.There were 16 boys and 14 girls in the observation group;they were(10.76±1.98)years old.The control group took manual reduction combined with dental arch splint fixation,and the observation group orthodontic treatment.The treatment efficacies,incidence rates of complications,periodontal indicators[plaque index(PLI),gingival index(GI),and bleeding index(BI)],treatment satisfaction,and recurrence rates were compared between the two groups.t and x2 tests were used.Results The total effective rate in the observation group was higher than that in the control group[96.7％(29/30)vs.80.0％(24/30)],with a statistical difference(x2=4.043;P=0.044).The incidence rate of complications in the observation group was lower than that in the control group[6.7％(2/30)vs.26.7％(8/30)],with statistical difference(x2=4.320;P=0.038).Before the treatment,there were no statistical differences in PLI,GI,and BI between the two groups(all P＞0.05).After the treatment,the PLI,GI and BI in the observation group were lower than those in the control group(1.24±0.52 vs.1.83±0.61,0.73±0.33 vs.1.21±0.52,and 0.73±0.33 vs.1.21±0.40),with statistical differences(t=4.032,4.269,and 5.070;all P＜0.05).The scores of fixation quality,aesthetics,and comfort in the observation group were higher than those in the control group(8.13±1.56 vs.6.34±1.45,8.12±1.13 vs.6.33±1.23,and 7.88±1.11 vs.5.21±1.34),with statistical differences(t=4.603,5.870,and 8.405;all P＜0.05).The recurrence rates 3 months after the treatment in both groups were 0;the recurrence rates 6 months and 1 year after the treatment in the observation group were lower than those in the control group[3.3％(1/30)vs.20.0％(6/30)and 6.7％(2/30)vs.26.7％(8/30)],with statistical differences(x2=4.043 and 4.320;both P＜0.05).Conclusion Orthodontic treatment for children with traumatic tooth dislocation is effective and can reduce the incidence of complications,maintain periodontal health,and improve the satisfaction,so it is worth being generalized.
