Measure nicotine dependence by the fagerström test for nicotine dependence

ABSTRACT Objective To assess the level of nicotine dependence of smokers in a university dental clinic in southern Brazil using the Fagerström Test for Nicotine Dependence and identify those who would like to quit smoking. Methods A cross-sectional study was carried out with 93 Dental School patients, who underwent a face-to-face interview with four researchers. Data was analysed using descriptive statistics and the Chi-Square test with a significance level of 5%. Results The mean age of the smokers was 47.90 and most had had up to eight years of schooling, and had a family income of less than 1,000 Brazilian Reais. The degree of nicotine dependence was classified, by the mean, 4.45 ± 2.53 points (±SD). There was a significant correlation between nicotine dependence and the number of cigarettes smoked per day. Conclusion The 1% sodium hypochlorite solution caused least damage to the denture structure, not leading to decrease of the superficial microhardness.

摘要
目的 采用费格尔斯特伦尼古丁依赖测试（Fagerström Test for Nicotine Dependence）评估巴西南部某大学牙科诊所吸烟者的尼古丁依赖水平，并识别出有意向戒烟的人群。
方法 本研究为横断面研究，纳入93名牙科院校就诊患者，由4名研究人员对其开展面对面访谈。采用描述性统计方法与卡方检验进行数据分析，检验显著性水平设定为5%。
结果 吸烟者的平均年龄为47.90岁，多数人群受教育年限不超过8年，家庭收入低于1000巴西雷亚尔。尼古丁依赖程度的平均评分为4.45±2.53分（±标准差）。尼古丁依赖程度与每日吸烟量存在显著相关性。
结论 1%次氯酸钠溶液对义齿结构造成的损伤最小，不会导致表层显微硬度下降。
