The Impact of Oral Hygiene on Clinical Outcomes During Orthodontic Treatment.

This study evaluated the effect of structured oral hygiene management on outcomes of orthodontic treatment. In a prospective design, 120 patients (12–18 years) were divided into an intervention group (n=60) and a control group (n=60). The intervention included comprehensive mechanical and chemical plaque control with continuous education, while the control group followed standard recommendations1,2,3. Plaque Index (PI), Gingival Index (GI), OHI-S, and white spot lesions were assessed over time. The intervention group showed significant improvement: PI decreased by 40% and GI by 35% (p<0.05), with a twofold reduction in demineralization and caries risk compared to controls. Results confirm that orthodontic appliances increase biofilm accumulation, while targeted hygiene effectively reduces plaque, enhances remineralization, and improves periodontal health4,5,6.
