This study was done to analyse the influence of fixed dental prosthesis (FDP) on brain function by analysing power spectral density of partially edentulous patients.
The study included unilateral missing mandibular molar replacement patients. The patients were restored with three-unit metal ceramic FDP restorations. The cognitive function was analysed with a mental state questionnaire. Power spectral density (PSD) analysis of EEG alpha waves was made pre- treatment, post treatment and 3 months after FDP treatment to analyse the brain function. The data in various phases were obtained before and after chewing. The results were statistically analysed.
The mean pre and post treatment PSD was 0.0175 (SD ±0.0132) and 0.0178 (SD ±0.0135). The mean post treatment PSD after three months was 0.024 (SD± 0.019). The results were analysed with repeated ANOVA and were statistically significant. (p<0.01).
The study displayed improvement in brain function of partially edentulous patients with FDP rehabilitation.
本研究旨在通过分析部分牙列缺损患者的功率谱密度，来分析固定义齿（FDP）对脑功能的影响。
本研究纳入单侧下颌磨牙缺失的修复患者。患者采用三单位金属烤瓷固定义齿修复。采用精神状态问卷分析认知功能。在治疗前、治疗后以及固定义齿治疗后3个月进行脑电图α波的功率谱密度（PSD）分析，以分析脑功能。在咀嚼前后获取各阶段的数据。对结果进行统计学分析。
治疗前和治疗后的平均PSD分别为0.0175（标准差±0.0132）和0.0178（标准差±0.0135）。三个月后的治疗后平均PSD为0.024（标准差±0.019）。采用重复方差分析对结果进行分析，具有统计学意义（p<0.01）。
本研究显示，通过固定义齿修复，部分牙列缺损患者的脑功能得到改善。
