Abstract
Objective: To evaluate the feasibility of residual root extraction without preoperative ASA withdrawal and the reasonable preoperative ASA suspension time.Methods: 90 cardiovascular and cerebrovascular disease cases who take ASA for disease prevention (time more than 2 weeks; dosage: 100 mg/d) were enrolled in this study.All cases were divided into 3 groups: Group A, ASA continuation group, Group B, ASA 3 day suspension group, and Group C, ASA 5 day suspension group.After upper single tooth (residual root) extraction was performed (10 anterior teeth, 10 premolars, and 10 molars in each group), condition of the socket coagulation was evaluated (class Ⅰ-Ⅵ, from ideal to undesirable) and comparison was implemented.Results: ①Class Ⅴ and Ⅵ of socket coagulation cases did not appear in all 3 groups.②For anterior tooth extraction, all cases appeared in class Ⅰ and Ⅱ coagulation.③For premolar extraction, the percentages of class Ⅲ coagulation was 20% and class Ⅳ was 10% in Group A.No class Ⅲ and class Ⅳ coagulatin cases were appeared in Group B and Group C .④For molar roots extraction, the percentages of class Ⅲ and Ⅳ cases in Group A (30% and 10% respectively) were higher than those in Group B (10% and 0 respectively) and Group C ( 0 and 0 respectively).Conclusion: ① For anterior tooth, preoperative ASA continuation is feasible.② For premolar and molar, preoperative 3 day ASA suspension is necessary to minimize postoperative bleeding risk unless it can lead to very high incidence of vascular thrombosis; for cases with very high ASA withdrawal risk, preoperative ASA continuation is feasible with strengthened socket haemostatic measures.关键词
