摘要: Objectives: The aim of this investigation was to assess the oral Non-Candida albicans colonization (ONCAC) in a group of teenagers and young adults while being treated with a fixed orthodontic appliance (FOA).Subjects and methods: The experimental group was selected from a sample of orthodontic patients who were clinically examined once to obtain baseline data before active treatment. The group comprised 210 subjects; 45 males, 165 females (mean age 21.6±4.5 years). Clinical, demographic data and risk factors were collected in standard questionnaire then each subject was directed to carry out oral rinsing using a phosphate-buffered saline solution, which was expectorated and processed for the recovery of Candida species on Sabouraud’s dextrose agar. Isolates were identifying by culturing on chromogenic Candida agar and noting species-specific colony characteristicsResults: The overall rate of Candida species oral colonization in FOA was 17.1%. The predominant Non-Candida species isolated was C. tropicals and Candida glabrata with total ONCAC rate equal to 5.2% significantly increased after the insertion of a FOA, as detected by the oral rinse (P< 0.05) techniques. The results also revealed an increase of ONCAC in male patients (8.9%) than female patients (4.2%),≤ 15 years patients (8.3%), and 16-21 years (8.2%) and regular smoking was significant associated risk factor (OR= 7.5, 95% CI= 1.9-28.9, P= 0.0007). There was no significant correlation between ONCAC with oral hygiene in fixed Orthodontic patients, while negative effects were found for regular rinsing (colonization= 12.9%, OR= 3.6, p= 0.03).Conclusion …
