This study aimed to investigate the effects of an oral health optimized diet on the composition of the supragingival oral plaque in a randomized controlled trial. Participants of the standard diet group (n = 5) had a diet high in processed carbohydrates and did not change their dietary behavior during the observation. The healthy diet group (n = 9) had to change the diet after 2 weeks from a diet high in processed carbohydrates to a diet low in carbohydrates, rich in omega‐3 fatty acids, rich in vitamins C and D, antioxidants and fiber for 4 weeks. Saliva and supragingival plaque samples were taken at the end of week two and eight of the observation period to investigate the composition of microbiota in saliva and supragingival plaque. Data were subjected to an exploratory analysis to identify significant differences. Statistically significant differences were only found in the healthy diet group between the baseline (week 2) and the final sample (week 8) for specific species in plaque and saliva samples. A reduction of the total counts of Streptococcus mitis group, Granulicatella adiacens, Actinomyces spp., and Fusobacterium spp. was found in plaque samples of the healthy diet group. In saliva samples of the healthy diet group, the total counts of Actinomyces spp. and Capnocytophaga spp. decreased. A diet low in carbohydrates, rich in omega‐3 fatty acids, rich in vitamins C and D, and rich in fiber reduced Streptococcus mitis group, Granulicatella adiacens, Actinomyces spp., and Fusobacterium spp. in the supragingival plaque.

口腔健康优化饮食可减少龈上口腔菌斑中潜在的龋齿和牙周细菌种类的负担：一项随机对照试验研究。

这项研究的目的是在一项随机对照试验中，研究优化口腔健康饮食对龈上口腔菌斑组成的影响。标准饮食组（n = 5）的参与者饮食中加工的碳水化合物含量高，并且在观察期间未改变饮食习惯。健康饮食组（n = 9）2周后，必须将饮食从富含加工碳水化合物的饮食改为低碳水化合物，富含omega-3脂肪酸，富含维生素C和D，抗氧化剂和纤维的饮食，持续4周。在观察期的第二周和第八周结束时采集唾液和龈上菌斑样品，以调查唾液和龈上菌斑中微生物群的组成。对数据进行探索性分析，以识别出显着差异。仅在健康饮食组中，在菌斑和唾液样品中的特定物种的基线（第2周）和最终样品（第8周）之间发现了统计学上的显着差异。减少了链球菌类微生物组的总计数，重度产灰质，放线菌菌属和梭菌属。在健康饮食组的牙菌斑样品中被发现。在健康饮食组的唾液样本中，放线菌的总数。和Capnocytophaga spp。减少了。饮食低碳水化合物，富含ω-3脂肪酸，富含维生素C和d，以及富含纤维减压缓症链球菌组，毗邻颗粒，放线菌属属和梭杆菌属。在龈上菌斑中。
