Increased dental biofilm commonly occurs during orthodontic treatment. The aim of this study was to evaluate the effect of a combined toothbrushing method on dental biofilm cariogenicity in patients with stainless steel (SSL) and elastomeric (EL) ligatures. At baseline (T1), 70 participants were randomized (1:1 ratio) to the SSL or EL group. Dental biofilm maturity was evaluated using a three-color-disclosing dye. The participants were instructed to brush their teeth using a combined horizontal-Charters-modified Bass technique. Dental biofilm maturity was reassessed at the 4-week follow-up (T2). We found that at T1, new dental biofilm was the highest, followed by mature and cariogenic dental biofilm in the SSL group ( < 0.05). In the EL group, cariogenic dental biofilm was highly observed, followed by mature and new dental biofilm ( < 0.05). After intervention, cariogenic dental biofilm significantly decreased in both groups ( < 0.05). Moreover, a marked decrease in cariogenic dental biofilm was observed in the EL group compared with the SSL group ( < 0.05). However, the change in mature dental biofilm in the groups was similar ( > 0.05). Our results demonstrated that the combined toothbrushing method reduced cariogenic dental biofilm in the SSL and EL groups.
正畸治疗期间牙菌斑通常会增加。本研究的目的是评估联合刷牙方法对使用不锈钢（SSL）和弹性体（EL）结扎丝的患者牙菌斑致龋性的影响。在基线（T1）时，70名参与者按1:1比例随机分为SSL组或EL组。使用三色显示染料评估牙菌斑成熟度。指导参与者使用联合水平-查特斯改良巴氏刷牙法刷牙。在4周随访（T2）时重新评估牙菌斑成熟度。我们发现，在T1时，SSL组新形成的牙菌斑最多，其次是成熟和致龋性牙菌斑（<0.05）。在EL组中，观察到致龋性牙菌斑最多，其次是成熟和新形成的牙菌斑（<0.05）。干预后，两组致龋性牙菌斑均显著减少（<0.05）。此外，与SSL组相比，EL组致龋性牙菌斑显著减少（<0.05）。然而，两组中成熟牙菌斑的变化相似（>0.05）。我们的结果表明，联合刷牙方法可减少SSL组和EL组的致龋性牙菌斑。
