宁夏城市地区成年人楔状缺损状况的研究

Study on the status of wedge-shaped defects among urban adults in Ningxia

摘要:

目的：调查宁夏城市地区成年人群楔状缺损状况，为其预防保健提供临床参考依据。方法：采用全国口腔流行病学调查方案，对宁夏地区4 064名成年人的楔状缺损状况进行调查分析，计算不同组别的楔状缺损患病率和治疗率；应用SPSS 11.5统计软件对结果进行分析。结果：①楔状缺损总患病率为42.67%，各年龄组患病率随着年龄的增长而升高，且各组间差异有统计学意义；在50～59岁组达到高峰但在60~69 岁组和≥70岁组反而降低。总治疗率为15.63%，且治疗率随年龄的增长而降低，各组间差异无统计学意义。②患病率表现为男性高于女性，指标在性别之间的差异无统计学意义。而治疗率表现为女性高于男性，指标在性别之间的差异有统计学意义。③楔状缺损患病率最高的是第１前磨牙（15.59%），第２磨牙楔状缺损患病率最低（0.26%）。各牙位间差异均有统计学意义。上颌牙齿楔状缺损患病率高于下颌牙齿，左侧牙齿患病率高于右侧，且２组指标间的差别均有统计学意义。治疗率最高者为第１前磨牙，且不同牙位组间的差异大多有统计学意义。④楔状缺损的发生与刷牙方式密切相关。结论：宁夏城市地区成年人楔状缺损与年龄和牙位有明显关系。其患病率高于治疗率，需要加强口腔预防与保健的宣传教育。

Abstract:

Objective：To investigate the status of wedge-shaped defects among adults in Ningxia，thus to provide clinical references for the prevention of this disease. Methods：Totally 4 064 adults in Ningxia were investigated in this study according to the criterion issued by China oral health epidemiology survey protocol. The incidence and therapy rate of wedge-shaped defects in different groups were calculated. SPSS 11.5 statistical software was applied to analyze the results. Results：①The overall incidence of wedge-shaped defects was 42.67%. The incidences were increased with the growth of age and there were significant differences among different age groups. It was peaked at the age between 50 and 59，but was decreased at the age between 60 and 69 and more than 70. The over－all therapy rate was 15.63%. The therapy rates were reduced with the growth of age and the differences were statistically significant among different age groups. ②The incidence was higher in male than in female without statistical differences. The therapy rate was high in male than in female with statistical differences. ③The place with the highest incidence of wedge-shaped defects was the first premolar（15.59%），while that with the lowest incidence was the second-molar（0.26%）. The differences in the different teeth were statistically significant. The incidence of wedge-shaped defects was higher in maxilla teeth than in mandible teeth and the incidence was higher in the left teeth than in the right teeth with significant differences. The therapy rate of the first premolar was the highest，and the differences in the different teeth were statistically significant.④The method of teeth-brushing was significantly related with wedge-shaped defects. Conclusions：The incidence of wedge-shaped defect is related with tooth location and age in Ningxia. Its incidence is higher than the therapy rate. So it is necessary to strengthen the propaganda of oral cavity of prevention and protection for adults in urban of Ningxia.
