The aim of this study was to investigate the predictive value of the traditional multidimensional health locus of control (MHLC) scale, a corresponding dental health locus of control (DHLC) scale and dental health values (DHVs) regarding students' dental health before and after a video programme that presented information about dental diseases and instructions on oral hygiene.
A group of 217 university students participated in this study. Before the video programme was presented, assessments were made of MHLC, DHLC and DHVs. Plaque and gingival indices were obtained in a clinical examination conducted before (plaque index [PLI] 1 and gingival index [GI] 1) and 10 weeks after (PLI 2 and GI 2) the presentation of the programme.
The percentage of tooth surfaces exhibiting plaque and of sites involving gingivitis decreased and was statistically significant between baseline and re-examination for both males and females. The females exhibited statistically significant better PLI 1 and GI 1 values and stronger DHVs than males. Also, better GI 1 values were found to be statistically significant and related to stronger DHVs for females. A stronger trust in the dental health personnel regarding the dental health was related to more gingivitis at the initial examination (GI 1). For males, stronger internal DHLC was related to more plaque at the final examination (PLI 2).
The only psychological scales that showed some relationship to the measures of dental health were DHLC and DHVs. Gender was the strongest related variable to dental health.
本研究旨在调查传统的多维健康控制点（MHLC）量表、相应的牙齿健康控制点（DHLC）量表以及牙齿健康价值观（DHV）对于学生在观看关于牙齿疾病信息及口腔卫生指导的视频节目前后牙齿健康状况的预测价值。
一组217名大学生参与了本研究。在播放视频节目之前，对MHLC、DHLC和DHV进行了评估。在节目播放前（菌斑指数[PLI]1和牙龈指数[GI]1）以及播放后10周（PLI 2和GI 2）进行的临床检查中获取菌斑和牙龈指数。
出现菌斑的牙面百分比和涉及牙龈炎的部位在基线和复查之间均有所下降，且在男性和女性中均具有统计学意义。女性的PLI 1和GI 1值在统计学上显著优于男性，且DHV更强。此外，对于女性而言，更好的GI 1值在统计学上具有显著意义，并且与更强的DHV相关。在初次检查时（GI 1），对牙齿健康人员在牙齿健康方面的更强信任与更多的牙龈炎相关。对于男性而言，更强的内在DHLC与最终检查时（PLI 2）更多的菌斑相关。
唯一显示出与牙齿健康测量指标有某种关系的心理量表是DHLC和DHV。性别是与牙齿健康最相关的变量。
