摘  要:目的:探讨异常吞咽对牙根吸收的影响。方法:选择11-16岁异常吞咽患者和正常吞咽患者各24名,拍全口曲面断层片,分别测量2组上下颌8个切牙的牙根吸收等级,并经过计算机进行统计学检验。结果:2组的牙根吸收等级差异有统计学意义(P〈0.05)。结论:异常吞咽是牙根吸收的高危因素。Objective: To evaluate the degree of the root resorption in tongue thrusting. Methods: 24 patients with tongue thrusting and 24 patients with normal swallowing were selected. All patients were 11-- 16 years old. radio- graphs taken were used to evaluate the degree of root resorption on upper and lower incisors. x^2 test was used for statistical analysis. Results: The degree of root resorption on incisors with tongue thrusting was significantly differ- ent from that with normal swallowing. Conclusion: Tongue thrusting may increased root resorption.
