Orthodontic treatment with fixed appliances is associated with changes in oral microbiota, including increased colonization. The fungus can cause oral lesions and infections such as candidiasis and angular cheilitis, and is harmful to both the patient and the orthodontist. Poor hygiene facilitates the colonization of these microorganisms. The key aim was to quantify the colonization of in patients prior to beginning orthodontic treatment, and during the treatment process.
A total of 124 patients (43 males and 80 females) with a mean age of 19.5 years, who required treatment with metal or aesthetic (ceramic) braces, were studied. Microbiological samples were taken from the oral cavity using the swab technique throughout the treatment and cultured on a Sabouraud Dextrose Agar plate and, if positive, cultured on a CHROMagar® Candida plate.
In contrast to other published studies, no statistically significant increase in colonization was observed during the orthodontic treatment. The fixed appliances had no influence on the presence, absence or level of colonization by and there were no significant differences between the different appliances studied.
Our study showed that frequency of oral hygiene measures by study participants did not affect the rate of oral carriage of in a statistically significant manner. This observation contrasted with published literature, which suggests that thorough brushing is important to prevent the build-up of species.

使用固定矫治器进行正畸治疗与口腔微生物群的变化有关，包括定植增加。真菌可引起口腔病变和感染，如念珠菌病和口角炎，对患者和正畸医生均有害。卫生条件差会促进这些微生物的定植。关键目标是在开始正畸治疗前以及治疗过程中对患者口腔内真菌的定植情况进行量化。
共研究了124例患者（43例男性和80例女性），平均年龄19.5岁，这些患者需要使用金属或美观（陶瓷）矫治器进行治疗。在整个治疗过程中，采用拭子技术从口腔采集微生物样本，并接种在沙氏葡萄糖琼脂平板上培养，若呈阳性，则接种在科玛嘉念珠菌显色平板上培养。
与其他已发表的研究不同，在正畸治疗期间未观察到真菌定植有统计学意义的增加。固定矫治器对真菌的存在、缺失或定植水平没有影响，在所研究的不同矫治器之间也没有显著差异。
我们的研究表明，研究参与者的口腔卫生措施频率对口腔真菌携带率没有统计学意义上的显著影响。这一观察结果与已发表的文献相反，文献表明彻底刷牙对于防止真菌种类的积聚很重要。正畸学、固定矫治器、口腔微生物群、白色念珠菌。
