The main aim of this thesis was to study the impact of oral health and oral prostheses on oral health-related quality of life (OHRQOL) in an adult Swedish population. Additional aims were to study social inequalities in oral health, attitudes towards the cost for dental care and dental care utilization. The study base was 1294 responses to a questionnaire from a random sample of 1974 persons aged 50-75 years, all of whom were resident in the County of Skine, Sweden. There was an association between impaired dental conditions and poor social conditions. Low dental care utilization covaried with impaired dental conditions and with stating a perceived need to obtain dental care but with no possibility to obtain it because of a cost barrier. In factor analysis, three factors captured 22 variables that aimed to measure OHRQOL. The constituent variables were summed into three index variables interpreted as oral health impact on everyday activities, on a psychological dimension and on oral function. The three variables were set as dependent variables in regression models with the independent variables social attributes, individual attributes, dentures, number of teeth and dental care attitudes. The models were run in three steps taking into account the interaction between the type of denture and the number of remaining teeth. The number of remaining teeth was more important than the type of denture when explaining OHRQOL. The type of replacement, in terms of fixed or removable denture, was less important for those with few or no remaining teeth, than for all others. OHRQOL was also explained by general health in relation to age peers as well as by varying attitudes towards dental care costs. Statistically significant interactions were observed between the number of remaining teeth and the type of denture when explaining OHRQOL. As a whole the thesis shows that social and dental conditions and cost for dental care play a great role for dental care utilization as well as for OHRQOL. Prosthodontics has an important role, where type of replacement interacts with tooth loss in its effect on QOL.
本论文的主要目的是研究口腔健康及口腔修复体对瑞典成年人群口腔健康相关生活质量（OHRQOL）的影响。其他目的包括研究口腔健康方面的社会不平等现象、对牙科护理费用的态度以及牙科护理的利用情况。研究样本为从1974名年龄在50 - 75岁的人群中随机抽取的1294份问卷回复，所有受访者均居住在瑞典斯科讷郡。牙齿状况受损与社会条件较差之间存在关联。牙科护理利用率低与牙齿状况受损以及表示感觉有必要接受牙科护理但因费用障碍而无法获得护理的情况相关。在因子分析中，三个因子涵盖了旨在衡量OHRQOL的22个变量。这些构成变量被汇总为三个指数变量，分别解释为口腔健康对日常活动、心理维度和口腔功能的影响。这三个变量被设定为回归模型中的因变量，自变量包括社会属性、个体属性、假牙、牙齿数量和对牙科护理的态度。模型分三步运行，同时考虑假牙类型与剩余牙齿数量之间的相互作用。在解释OHRQOL时，剩余牙齿数量比假牙类型更重要。对于剩余牙齿很少或没有剩余牙齿的人来说，固定或可摘假牙这种修复类型的重要性低于其他所有人。OHRQOL还可通过与同龄人相比的总体健康状况以及对牙科护理费用的不同态度来解释。在解释OHRQOL时，观察到剩余牙齿数量与假牙类型之间存在统计学上的显著相互作用。总体而言，本论文表明社会和牙齿状况以及牙科护理费用对牙科护理的利用和OHRQOL都起着重要作用。在口腔修复学中，修复类型与牙齿缺失在对生活质量的影响方面存在相互作用，这一点具有重要意义。
