Abstract:
Objective:To investigate the clinical characteristics and potential predisposing factors of the external cervical resorption(ECR).Methods:22 ECR cases with 38 affected teeth from 2016 to 2022 were retrospectively reviwed.Descriptive analysis combined with single factor analysis was used to study the clinical characteristics and influencing factors of ECR.Results:Maxillary anterior teeth(34.2％)were the most affected by ECR.Univariate analysis showed that ECR was more commonly noted in teeth without percussion pain and palpation pain,the probing depth of the periodontal pocket was greater than 3mm,with pulp activity reaction,without forma-tion of abscess and/or sinus tract,and without periapical lesions.There were statistically significant differences in percussion tender-ness,palpation tenderness and probing depth among the different Heithersary stages(P＜0.05).In the advanced cases,deep periodon-tal pockets and abscess formation were observed.The most common related dental factors of ECR were orthodontic treatment(15.87％)and dental traumatic injury(28.57％).Conclusion:ECR affected teeth often lack of clinical signs and symptoms.Radiology is the key to early diagnosis.
