N2 - Objectives: As reported by the existing literature, calcium-channel blockers (CCB) can lead to gingival enlargement. The aims of this study were to investigate the factors associated with gingival enlargement in patients on CCB and to assess the saliva and gingival crevicular fluid (GCF) profile of patients on CCB with gingival enlargement. Methods: A total of 131 participants were included. Data were collected from 91 patients taking CCB for treatment of systemic hypertension. The presence of drug-induced gingival enlargement (DIGE) was assessed clinically and associated with patient factors. Patients with DIGE were group-matched for gender and ethnicity with an equal number of consecutive CCB non-DIGE patients (control 1), no-CCB no-DIGE (control 2) and periodontally healthy with no DIGE (control 3) for the saliva and GCF analysis. A bead-based multiplex immunoassay was used to assess a panel of biomarkers. Results: Twenty-two percent of patients on CCB were diagnosed with DIGE. Lack of daily interdental cleaning and self-reported diagnosis of type II diabetes were associated with the diagnosis of DIGE. When analysing patients only on CCB, those with DIGE had higher GCF levels of vascular endolthelial growth factor (VEGF) (p = 0.032), epidermal growth factor (EGF) (p = 0.030) and matrix metalloproteinase-8 (MMP-8) (p = 0.008). Among the salivary markers, only MMP-8 showed a statistically significant difference across groups (p < 0.001). Conclusions: This is the first study investigating saliva and GCF biomarkers in patients with DIGE and different control groups, suggesting that causes of the overgrowth might involve inflammatory processes, tissue damage pathways, and potentially an impact on growth factors like VEGF. Future research should verify these results in independent populations and explore the underlying pathogenic mechanisms in-depth. Clinical significance: Calcium-channel blockers (CCB) can lead to gingival enlargement. This study confirms lack of interdental cleaning and type II diabetes as risk factors. Elevated levels of VEGF, EGF, and MMP-8 in gingival crevicular fluid and MMP-8 in saliva suggest inflammatory processes and growth factors might play roles in this condition.
