How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Fixed orthodontic appliances are widely used for the correction of dentofacial anomalies; however, their presence in the oral cavity creates additional plaque-retentive areas and increases the risk of inflammatory periodontal diseases, particularly during the early stages of treatment. Aim. To assess the dynamic changes in periodontal risk indicators in patients undergoing orthodontic treatment with fixed appliances. Materials and Methods. A prospective observational study included 88 patients aged 16–34 years receiving orthodontic treatment with fixed bracket systems. Oral hygiene status was evaluated using the Simplified Oral Hygiene Index (OHI-S), and gingival inflammation was assessed using the Gingival Index (GI). Measurements were performed before appliance placement and at 4 and 8 weeks after treatment initiation. Descriptive statistics and paired comparisons were applied to analyze changes over time, with statistical significance set at p < 0.05. Results. Four weeks after bracket placement, a significant deterioration in oral hygiene and gingival condition was observed, with OHI-S increasing from 1.26 ± 0.22 to 2.34 ± 0.36 and GI increasing from 0.61 ± 0.15 to 1.56 ± 0.27. After implementation of preventive and hygienic interventions, both indices significantly improved by week 8, with OHI-S decreasing to 1.11 ± 0.19 and GI to 0.64 ± 0.16, indicating effective control of inflammatory changes. Conclusion. Regular monitoring of periodontal risk indicators during orthodontic treatment with fixed appliances enables early detection of inflammatory changes and supports effective prevention of periodontal complications through timely preventive interventions.
