Removable oral appliances form an integral part of interceptive orthodontic procedures. Bacterial colonization leading to halitosis and poor color stability are the major disadvantages of the same in spite of patient acceptability. The aim of the present study was to evaluate bacterial colonization, color stability, and halitosis from the oral appliances fabricated using cold cure, cold cure under pressure pot, heat cure acrylics, thermoforming sheet, Erkodur and antibacterial thermoforming sheet, Erkodur-bz.
A group of 40 children was divided into five groups and the appliances were delivered. Bacterial colonization and halitosis were evaluated before giving the appliance to the patient after 1 and 2 months. Color stability was evaluated before giving the appliance to the patient and then after 2 months. This study was designed as a single-blinded randomized clinical trial.
Results have shown that after 1 and 2 months, bacterial colonization was higher from the appliances fabricated with cold cure and was lower for the Erkodur group, which was statistically significant. Color stability was more from the appliances fabricated with Erkodur and was less for cold cure, which was statistically significant. Halitosis after 1 month was more from the appliances fabricated with cold cure and less from Erkodur group, which was statistically significant. After 2 months, halitosis was more from the cold cure group and less from Erkodur group, which was not statistically significant.
Thermoforming sheet, Erkodur showed better results than other groups in terms of bacterial colonization, color stability, and halitosis.
When removable appliances are indicated for minor orthodontic tooth movement, Erkodur is preferable due to the advantages of easy fabrication and less bacterial colonization.

可摘式口腔矫治器是阻断性正畸治疗的重要组成部分。尽管患者易于接受，但细菌定植导致口臭和颜色稳定性差是其主要缺点。本研究旨在评估使用冷固化、压力罐冷固化、热固化丙烯酸树脂、热成型片材、爱尔康杜尔（Erkodur）以及抗菌热成型片材爱尔康杜尔 - bz（Erkodur - bz）制作的口腔矫治器的细菌定植情况、颜色稳定性和口臭情况。
将40名儿童分为五组并佩戴矫治器。在将矫治器交付给患者前、佩戴1个月和2个月后评估细菌定植和口臭情况。在将矫治器交付给患者前以及2个月后评估颜色稳定性。本研究设计为单盲随机临床试验。
结果显示，1个月和2个月后，冷固化制作的矫治器细菌定植率更高，而爱尔康杜尔组更低，差异具有统计学意义。爱尔康杜尔制作的矫治器颜色稳定性更好，冷固化制作的矫治器颜色稳定性较差，差异具有统计学意义。1个月后，冷固化制作的矫治器口臭情况更严重，爱尔康杜尔组较轻，差异具有统计学意义。2个月后，冷固化组口臭情况更严重，爱尔康杜尔组较轻，但差异无统计学意义。
在细菌定植、颜色稳定性和口臭方面，热成型片材、爱尔康杜尔比其他组表现更好。
当可摘矫治器用于轻微正畸牙齿移动时，由于易于制作且细菌定植较少，爱尔康杜尔更具优势。
