To determine if the fixed appliance will affect the periodontal health. Sixteen patients with malocclusion were randomly selected. One week before the fixed appliance placement, plaque index (PLI), bleeding index (BI), pocket depth (PD) and subgingival plaque were assessed. The observed value was served as the baseline records. After the fixed appliance placement, significant differences were found in PLI, BI, PD and these values were significantly greater than the baseline. Subgingival microfloral shifted to a more disease-inducing microflora and there was a statistically significant increase in spirochetes and fusiform. Fixed appliance placement will affect the periodontal health. Therefore, it is very important to strengthen the oral hygiene instruction to the people who receive the treatment of fixed appliance.
