Orthodontic appliances can enhance plaque accumulation, and this can cause gingival inflammation. Halitosis of oral origin is associated with microbial metabolism on the tongue and in the saliva, dental plaque, and the amount of volatile sulfide-containing compounds. This study used a Halimeter to investigate fixed orthodontic therapy-associated increases in the oral malodor over a year.
Thirteen orthodontic patients with Angle Class I malocclusions receiving fixed orthodontic therapy formed the study group, and 12 dental students without any dental treatment formed the control group. The Halimeter was used to examine oral malodor by detecting volatile sulfur compounds (VSC). Plaque index (PI), gingival index (GI), and probing pocket depth (PPD) were also measured in both groups. The subjects in the study group had one visit before the orthodontic treatment started and seven visits during orthodontic therapy (1, 3, 5, 7, 9, 11, and 13 months after bonding), while the subjects in the control group had three visits, once per subsequent month.
Oral malodor was significantly increased in the fixed orthodontic treatment group during treatment (p < .05). Increases were also observed in the PI, GI, and PPD measures (p < .05). The results of the control group were stable (p > .05).
Oral malodor increased during fixed orthodontic treatments and reached a critical level 7 months later.
正畸矫治器会增加牙菌斑的积聚，进而导致牙龈炎症。口腔源性口臭与舌部、唾液、牙菌斑中的微生物代谢以及含挥发性硫化物的化合物量有关。本研究使用口臭测量仪调查固定正畸治疗一年期间口腔异味的增加情况。
13名接受固定正畸治疗的安氏I类错牙合畸形正畸患者组成研究组，12名未接受任何牙科治疗的牙科学生组成对照组。使用口臭测量仪通过检测挥发性硫化物（VSC）来检查口腔异味。两组还测量了菌斑指数（PI）、牙龈指数（GI）和探诊袋深度（PPD）。研究组的受试者在正畸治疗开始前就诊一次，在正畸治疗期间就诊七次（粘结后1、3、5、7、9、11和13个月），而对照组的受试者就诊三次，随后每月一次。
固定正畸治疗组在治疗期间口腔异味显著增加（p < 0.05）。PI、GI和PPD测量值也有所增加（p < 0.05）。对照组的结果稳定（p > 0.05）。
固定正畸治疗期间口腔异味增加，并在7个月后达到临界水平。
