研究概览
简要总结
The primary objective of this study will be to evaluate the effect of two week pre-surgical rinsing with an antimicrobial mouthrinse containing 0.2% w/v Chlorhexidine digluconate on the total number of plaque bacteria in the mouth 3 days post implant surgery. The study will be conducted at Eastman Clinical Investigation Centre (ECIC), University College London (UCL) Eastman Dental Institute. Participants will be those who require a single and simple surgical implant to be placed, and will be recruited from new patient referrals within the Eastman Dental Hospital

结局指标
主要结局
Total Number of Detectable Plaque Bacteria Sampled 3 Days Post Implant Surgery
时间窗: At Day 3
The examiner identified three plaque sampling sites as follows: surgical site, contralateral site to the surgical site and tongue. An individual cotton swab was used at each identified site for up to 20 seconds in order to harvest a plaque sample and immediately be placed into 1mL phosphate buffered saline in a sterile Eppendorf tube. The samples were analysed using quantitative polymerase chain reaction (qPCR) which determined the total number of bacteria in a sample by quantifying the number of 16S ribosomal ribonucleic acid (rRNA) genes in the sample. The number of bacteria in each of the three identified plaque sampling sites (surgical site, contralateral site to the surgical site and tongue) for each participant were summed to calculate the total number of bacteria for each participant.
次要结局
- Total Number of Detectable Plaque Bacteria Sampled at Implant Surgery (at Pre-rinse, Pre, Mid and Post Implant Surgery) and Post Implant Surgery (at Day 1 and 7)(At Day 0 (pre-rinse, pre, mid and post implant surgery), Day 1 and 7)
- Area Under the Curve (AUC) for the Total Number of Plaque Bacteria in the Mouth Post Implant Surgery(Up to 7 days post implant surgery)
- Total Number of Recoverable Viable Bacteria in the Aerosol Generated During Dental Prophylaxis(At Baseline)
