Fixed orthodontic appliances create areas of plaque stagnation leading to an increase in the volume, structure, and composition of plaque. This increases the chances of decalcification and white spot lesions. Oil pulling, an ancient practice involving swishing oil in the mouth, has demonstrated a significant reduction in plaque scores after 45 days, and a reduction in salivary Streptococcus mutans concentration in few studies done in nonorthodontic subjects. The aim was to compare the concentration of S. mutans in plaque around orthodontic brackets in patients using oil pulling with sesame oil and those on routine oral hygiene.
Twenty subjects requiring fixed orthodontic treatment were divided into two equal groups: Group A-Oil pulling and Group B-Control. All subjects were instructed to follow common oral hygiene methods and in addition, Group A was instructed to perform oil pulling for 30 days starting 1 month after placement of fixed appliances. Plaque specimens were collected from labial surfaces of maxillary lateral incisors and quantification of S. mutans was done using real-time polymerase chain reaction. Mean and standard deviations for descriptive statistics, paired, and unpaired sample t-tests were analyzed.
Comparison of S. mutans concentration between T1 and T2 demonstrated a significant difference in both control and study groups. The experimental group showed significantly lesser S. mutans concentration compared to the control group.
Oil-pulling therapy with sesame oil resulted in a statistically significant reduction in the concentration of S. mutans in the plaque around orthodontic brackets.
固定正畸矫治器会造成菌斑停滞区，从而增加菌斑的体积、结构和组成。这增加了脱矿和白色斑点病变的可能性。油拔，一种涉及在口腔中搅动油的古老做法，已经证明在 45 天后可以显著降低菌斑评分，并且在一些非正畸受试者的研究中可以降低唾液变形链球菌浓度。目的是比较使用芝麻油进行油拔的正畸患者和常规口腔卫生的患者的正畸托槽周围菌斑中 S. mutans 的浓度。
20 名需要固定正畸治疗的受试者被分为两组：A 组-油拔和 B 组-对照组。所有受试者均被指示遵循常规口腔卫生方法，此外，A 组在固定矫治器放置 1 个月后开始进行为期 30 天的油拔。从上颌侧切牙唇面采集菌斑标本，并使用实时聚合酶链反应定量 S. mutans。使用描述性统计、配对和非配对样本 t 检验分析均值和标准差。
在 T1 和 T2 时比较 S. mutans 浓度，在对照组和实验组中均显示出显著差异。实验组 S. mutans 浓度明显低于对照组。
芝麻油的油拔疗法可使正畸托槽周围菌斑中 S. mutans 的浓度统计学上显著降低。
