Abstract

AIMS

To determine the influence of hard acrylic denture base materials on the blood flow of mandibular denture supporting mucosa over a period of six months time.

MATERIALS AND METHODS

Select fifteen edentulous patients of age 55-75 years. The blood flow of the mandibular denture supporting mucosa was measured bilaterally in the molar region and in the incisor region utilizing Ultrasound colour Doppler (2D and Duplex Imaging). Measurements were performed prior to denture insertion and later after the dentures were worn for 1 month, 2 months, 3 months, 4 months, 5 months and 6 months.

STATISTICAL ANALYSIS USED

Mean blood flow as measured by Ultrasound colour Doppler were tabulated significant changes if any at various time interval in comparison to baseline was assessed by Kruskalwallis ANOVA test followed by Wilkoxan sign rank test for pairwise comparison. (In the present study, < 0.05 was considered as the level of significance).

RESULTS

The denture supporting mucosa exhibited a progressive reduction in the blood flow both with hard denture. The blood flow change with hard denture was a reversible condition as the blood flow improved at the end of six months. Kruskalwallis ANOVA test revealed no significant change in the blood flow at any interval of time in comparison to base value ( = 0.133).

CONCLUSIONS

Within the limitations of the study denture supporting mucosa exhibited a progressive reduction in the blood flow with hard denture which was reversible.

摘要

目的

确定硬质丙烯酸义齿基托材料在六个月时间内对下颌义齿支持黏膜血流的影响。

材料与方法

选择15例年龄在55 - 75岁的无牙颌患者。使用超声彩色多普勒（二维和双功成像）双侧测量下颌义齿支持黏膜在磨牙区和切牙区的血流。在义齿佩戴前以及佩戴1个月、2个月、3个月、4个月、5个月和6个月后进行测量。

所用统计分析方法

将超声彩色多普勒测量的平均血流制成表格。通过Kruskalwallis方差分析检验评估与基线相比在不同时间间隔内是否有任何显著变化，随后进行Wilkoxan符号秩检验进行两两比较。（在本研究中，P < 0.05被视为显著性水平）。

结果

义齿支持黏膜在使用硬质义齿时均表现出血流逐渐减少的情况。使用硬质义齿时的血流变化是可逆的，因为在六个月结束时血流有所改善。Kruskalwallis方差分析检验显示与基线值相比，在任何时间间隔内血流均无显著变化（P = 0.133）。

结论

在本研究的局限性内，义齿支持黏膜在使用硬质义齿时表现出血流逐渐减少且这种情况是可逆的。
