Cognitive disorders are characterized by major impairments in functions such as memory, judgment, language and attention. One of the tests used to assess these disorders is called the Montreal Cognitive Assessment Test, which is one of the most recent tests known in this field. DMFT index is the most important dental index for evaluation of decayed, missing and filled teeth. Since alteration or damage to the sensory function of teeth can cause changes in chewing function and different levels of cognitive disorders. The objective of this study was to determine the relationship of DMFT index with cognitive disorders in people aged 25-55 in Rafsanjan in 2019.
This cross-sectional study was performed on 350 patients chosen by simple random sampling within age range of 25-55 years, referred to Rafsanjan Dental School in 2019. Patients' demographic information was recorded and each was given a consent form and also Montreal Cognitive Assessment Test. Dental examination regarding decayed, missing and filled teeth was then carried out by a dentist and The DMFT index was recorded. Data were then analyzed by SPSS version 21; value less than 0.05 was considered as significant level.
Data showed that the MOCA index had a negative significant relationship with DMFT ( = 0.001) and age ( = 0.001) and had a significant positive relationship with education ( = 0.001), but it had no significant relationship with gender ( = 0.853), time of last dental appointment ( = 0.231) and place of residence ( = 0.428). The effect of age ( = 0.67) and gender ( = 0.525) on the relationship of DMFT and MOCA was not significant. But the effect of education ( = 0.001), place of residence ( = 0.0003) and time of last dental appointment ( = 0.002) on it was significant.
The results of this study showed that the relationship between DMFT index and cognitive disorders was significant and the higher the score of this index, the more severe cognitive disorders.
认知障碍的特征是在记忆、判断、语言和注意力等功能方面存在重大损害。用于评估这些障碍的测试之一是蒙特利尔认知评估测试，它是该领域最新的测试之一。DMFT指数是评估龋齿、缺失牙和充填牙的最重要的牙科指数。由于牙齿感觉功能的改变或损害会导致咀嚼功能的变化以及不同程度的认知障碍。本研究的目的是确定2019年拉夫桑詹25至55岁人群中DMFT指数与认知障碍之间的关系。
本横断面研究于2019年对350名年龄在25至55岁之间、通过简单随机抽样选取的患者进行，这些患者被转诊至拉夫桑詹牙科学院。记录患者的人口统计学信息，每位患者都签署了知情同意书并接受了蒙特利尔认知评估测试。然后由一名牙医对龋齿、缺失牙和充填牙进行牙科检查，并记录DMFT指数。数据随后用SPSS 21版进行分析；P值小于0.05被视为显著水平。
数据显示，蒙特利尔认知评估（MOCA）指数与DMFT（P = 0.001）和年龄（P = 0.001）呈显著负相关，与教育程度呈显著正相关（P = 0.001），但与性别（P = 0.853）、上次牙科就诊时间（P = 0.231）和居住地点（P = 0.428）无显著关系。年龄（P = 0.67）和性别（P = 0.525）对DMFT与MOCA关系的影响不显著。但教育程度（P = 0.001）、居住地点（P = 0.0003）和上次牙科就诊时间（P = 0.002）对其影响显著。
本研究结果表明，DMFT指数与认知障碍之间的关系显著，该指数得分越高，认知障碍越严重。
