Objectives

The study aims to investigate dental anxiety in first- and final-year undergraduate dental students in India.

Design

Questionnaire Study Setting: BDS Students in four University dental colleges in India carried-out during 2013 and 2014.

Subjects (materials and methods)

The students (n = 614) were assessed using a pre-tested questionnaire. We estimated the level of dental anxiety by using the Modified-Dental-Anxiety-Scale (MDAS). ANCOVA and Mann–Whitney U, and Chi-squared contingency tests were employed to analyze the extensive dataset acquired. Univariate clustering analysis and principal component regression were also applied. Students had similar demographic and lifestyle patterns.

Interventions

Assessments of the level of dental anxiety amongst undergraduate dental students.

Main outcome measures

Mean ± SD MDAS scores for first- and final-year Bachelor of Dental Surgery (BDS) students were 12.96 ± 4.00 and 10.54 ± 3.41, respectively.

Results

Six hundred and fourteen (n = 614) students from four dental colleges were included in this study. In total 77% were female (n = 478) and 23% were male (n = 136). The mean age of the first- and final-year students were 18.31 and 21.54 years, respectively. First-year BDS students had dental anxiety score (Mean ± SD 12.96 ± 4.00) compared to that of the final year (10.54 ± 3.41), a difference which was very highly statistically significant (p < 0.0001).

Conclusion(s)

Dental anxiety was moderately higher amongst first year BDS students over that of final-year students but it is lesser than the dental phobic threshold level.

印度牙科一年级和最后一年级学生的牙科焦虑症

目标

该研究旨在调查印度一年级和最后一年的本科牙科学生的牙科焦虑症。

设计

问卷研究设置：印度四所大学牙科学院的 BDS 学生于 2013 年和 2014 年进行。

科目（材料和方法）

学生 ( n  = 614) 使用预先测试的问卷进行评估。我们使用改良的牙科焦虑量表 (MDAS) 估计了牙科焦虑的程度。采用 ANCOVA 和 Mann-Whitney U 以及卡方列联检验来分析获得的广泛数据集。还应用了单变量聚类分析和主成分回归。学生的人口统计和生活方式模式相似。

干预措施

评估本科牙科学生的牙科焦虑水平。

主要观察指标

第一年和最后一年牙科手术学士 (BDS) 学生的平均 ± SD MDAS 分数分别为 12.96 ± 4.00 和 10.54 ± 3.41。

结果

 本研究包括来自四所牙科学院的 614名 ( n = 614) 名学生。总共 77% 是女性（n  = 478），23% 是男性（n  = 136）。一年级和最后一年学生的平均年龄分别为 18.31 岁和 21.54 岁。BDS 一年级学生的牙科焦虑评分（平均值 ± SD 12.96 ± 4.00）与最后一年（10.54 ± 3.41）相比，差异具有非常高的统计学意义（p  < 0.0001）。

结论

BDS 一年级学生的牙科焦虑程度略高于最后一年的学生，但低于牙科恐惧症阈值水平。
