研究目的: |
1. 比较试验组与对照组义齿清洁方法在减少义齿上机会性呼吸道病原体方面的效果(通过呼吸道病原体的检出率、丰度及微生物组指数[ORPI]评估)。 2. 比较试验组与对照组义齿清洁方法在提高清洁程度方面的效果(通过半自动平面图像分析法评估菌斑面积百分比)。 3. 比较试验组与对照组义齿清洁方法在减少义齿性口腔炎方面的效果(依据Newton分级评估)。 4. 比较试验组与对照组义齿清洁方法在患者满意度方面的差异。 |

Objectives of Study: |
1. To compare the efficacy of the test and control denture cleaning interventions in reducing opportunistic respiratory pathogens on dentures [as assessed by the prevalence, abundance, and microbiome-based index of respiratory pathogens (ORPI)]. 2. To compare the efficacy of the test and control denture cleaning interventions in improving denture cleanliness (as assessed by the percentage plaque area coverage using semi-automated planimetric assessment). 3. To compare the efficacy of the test and control denture cleaning interventions in reducing denture stomatitis (as assessed by Newton’s Classification). 4. To compare the efficacy of the test and control denture cleaning interventions in terms of patient satisfaction. |

随机方法(请说明由何人用什么方法产生随机序列): |
受试者将按照四人为一组的区组随机法(ABBA)分配至研究的ARM 1或ARM 2组。随机分配序列将由牙医学院转化研究实验室的一名技术人员使用计算机随机数字生成系统生成,该技术人员不参与数据收集或分析工作。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Participants will be block randomised with a block of four (ABBA) into ARM 1 or ARM 2 of the study. The sequence of randomisation will be created by a computer random digit generation system conducted by a technical officer of the Translational Research Laboratory in the Faculty of Dentistry not involved in data collection or analyses. |
