BACKGROUND/PURPOSE: The aim of this study was to explore the presence and variability of oral in adolescents before and during treatment with fixed orthodontic appliances.
A total of 50 patients aged 10-18 years old were randomly selected for this study. Microorganism samples were obtained prior to and after orthodontic treatment and identified by culture methods. Molecular biology techniques were used to investigate the samples further and the effect of the orthodontic appliance on oral pathogenic yeasts was studied longitudinally.
The percentage of patients with candidiasis and the total number of colony-forming units significantly increased 2 months after orthodontic treatment. Changes in the type of oral candidiasis prior to and after treatment were significant.
Fixed orthodontic appliances can influence the growth of oral pathogenic yeasts among adolescents.
背景/目的:本研究旨在探讨青少年在使用固定正畸矫治器治疗前及治疗期间口腔念珠菌的存在情况及变异性。
本研究共随机选取50例年龄在10 - 18岁的患者。在正畸治疗前后获取微生物样本,并通过培养方法进行鉴定。采用分子生物学技术对样本进行进一步研究,并纵向研究正畸矫治器对口腔致病性酵母菌的影响。
正畸治疗2个月后,念珠菌病患者的百分比及菌落形成单位总数显著增加。治疗前后口腔念珠菌类型的变化显著。
固定正畸矫治器可影响青少年口腔致病性酵母菌的生长。
