Abstract:
Objective:To analyze the factors related to spontaneous re-eruption after intruded injury in permanent anterior teeth in children and adolescents.Methods:Clinical data from 5-to 17-year-old pa-tients who sustained intrusive luxation of permanent anterior teeth and treated in the Department of Pedia-tric Dentistry of Peking University School and Hospital of Stomatology from June 2015 to August 2024 were reviewed.Information of age,gender,degree of intrusion,direction of intrusion,tooth develop-ment,concomitant injuries,luxation and post-osteoclastic eruption of the adjacent teeth were recorded.The patients were divided into two groups based on whether they showed spontaneous re-eruption during advised observation after intrusion.Univariate and multifactor analysis were performed using Logistic re-gression.Results:Data from 170 teeth in 139 patients whose age ranging from 5.3-16.3 years[mean age(9.0±2.1)years]were examined.A gender disparity was observed among the patients,with 84 be-ing male and 55 being female.Among the 170 teeth,112 were categorized as successfully spontaneous re-eruption during advised observation after intrusion,while 58 were not.In terms of the degree of intru-sion,45 teeth(26.47％)had intrusion less than 3 mm,102 teeth(60.00％)experienced intrusion be-tween 3-7 mm,and 23 teeth(13.53％)were faced with intrusion exceeding 7 mm.As for the direction of intrusion,117 teeth(68.82％)were straight intrusion while mesial-distal and buccal-lingual intrusion respectively accounting for 17(10.00％)and 23(13.53％).Multivariate Logistic regression analysis showed that mesial-distal intrusion(OR=0.167,95％CI:0.031-0.9048,P=0.038),intrusion of＞7 mm(OR=0.065,95％CI:0.014-0.299,P＜0.001)and luxation of adjacent teeth(OR=0.369,95％CI:0.144-0.944,P=0.037)were independent risk factors for spontaneous re-eruption of trau-matically intruded permanent anterior teeth in children and adolescents during advised observation after intrusion,while intrusion of＜3 mm(OR=9.860,95％CI:2.430-40.009,P=0.001)and post-osteoclastic eruption of adjacent teeth(OR=4.712,95％CI:1.528-14.531,P=0.007)were inde-pendent protective factors.The possibility of spontaneous re-eruption in permanent anterior teeth during advised observation after intrusion was decreased by 61.1％with the increase of root development using Cvek's classification(OR=0.611,95％CI:0.408-0.914,P=0.017).Age(OR=1.077,95％CI:0.763-1.521,P=0.673)and laceration of gingival(OR=0.865,95％CI:0.290-2.578,P=0.794)didn't significantly affect the spontaneous re-eruption during advised observation after intrusion.Conclusion:In this study,mesial-distal intrusion,intrusion of＞7 mm and luxation of adjacent teeth were independent risk factors for spontaneous re-eruption of traumatically intruded permanent anterior teeth in children and adolescents during advised observation,while intrusion of＜3 mm and post-osteoclastic eruption of adjacent teeth were served as independent protective factors.
