Researchers then took saliva and tongue coating samples to measure bacteria levels and odour, causing compounds, including hydrogen sulphide. The volunteers then ate 90 grams of yoghurt a day for six weeks. At the end of the study, researchers took samples again. They found hydrogen sulphide levels decreased in 80% of participants. Levels of plaque and the gum disease gingivitis were also significantly lower among yoghurt eaters. Dr Nigel Carter, chief executive of the British Dental Health Foundation, said, "The foundation has long been drawing people's attention to sugar-free yoghurts as a healthy snack, so it is pleasing to hear that it may have oral health benefits we were previously unaware of."
然后研究者们提取了他们唾液和舌苔的样本，用于测量（口腔内的）细菌水平和能诱发异味的化合物，如硫化氢。 志愿者们在接下来的六周内每天饮用90克酸奶。 在研究快结束时，研究者们再次采集了样本。他们发现受试者口腔内的硫化氢含量降低了80%。 此外，在饮用酸奶的受试者当中，牙菌斑和牙龈炎的发病率也显著降低。 英国牙科保健基金会负责人奈杰尔·卡特医生说：“基金会一直在努力激发人们对无糖酸奶这种健康零食的兴趣，因此我们很高兴听到它能促进口腔健康，这是我们以前没有意识到的。”
