Preliminary investigation and analysis of the association between ICVD and dentition defect among part of the old patients in Harbin / 中国基层医药

ABSTRACT

Objective To investigate and analyze if there is association between ischemic cerebral vascular disease (ICVD)and the time factor of dentition defect or not by the way of questionnaire.The investigation and analy-sis will provide the theoretical basis and reference in order to study the relationship between oral disease and brain functional disease as well as ICVD.Methods 159 elderly patients who diagnosed definitely as brain functional dis-ease and dentition defect or oral prosthesis at the same time were selected.The oral condition and cerebral vascular disease history were recorded and analyzed.Results There were only 27 individuals who had teeth missing without ICVD,accounted for 16.98%.The rest of 132 individuals who had both teeth missing and ICVD accounted for 83.02%.The number of individuals who lose back teeth was larger than the number of that who suffered from ICVD (χ2 =32.360,P <0.01).The longer length of time that losing teeth took,the bigger risk that patients suffered from ICVD.Spearman rank correlation analysis result was r =0.437,P <0.01.It meaned that time was another factor. Conclusion There is certain association between the length of lacking teeth and ICVD.Missing back teeth has a bigger effect on ICVD than missing front teeth.Furthermore,the longer time that losing teeth takes,the higher risk that patients suffer from ICVD.However,it is not clear how the length of time effects ICVD.Further study is still needed.
