    The gingival crevicular fluid levels of growth factors in patients with amlodipine-induced gingival overgrowth: A pilot study

    Background: Amlodipine, calcium channel blocker (CCB), is used in the management of cardiovascular diseases which causes gingival overgrowth (GO). The growth factors may have a role in the pathogenesis of amlodipine-induced GO. Objectives: This pilot study aimed to investigate the growth factors including transforming growth factor-b1 (TGF-b1), platelet-derived growth factor-BB (PDGF-BB), and basic fibroblast growth factor (bFGF) in gingival crevicular fluid (GCF) of patients with amlodipine-induced GO and compare with of healthy subjects. Methods: GCF samples were collected from 56 sites presenting GO (GO + group) and from 38 sites not presenting GO (GO- group) of 5 patients using amlodipine for more than one year, and from 45 sites (control group) of 5 healthy subjects. The levels of TGF-b1, PDGF-BB, and bFGF were determined by using ELISA kits. Results: The mean concentration of TGF-b1 in GCF samples of GO + group (9.50 +/- 7.30 ng/ml) was higher than both GO- group (2.07 +/- 0.50 ng/ml) and control group (2.74 +/- 1.01 ng/ml) (P = 0.014). No significant difference was found among the groups in the GCF levels of PDGF-BB (P = 0.767). bFGF was detected in only 33% of the sites from patients. Conclusion: These preliminary results suggest that TGF-b1 may play a crucial role in the pathogenesis of amlodipine-induced GO.

    © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.Objectives: The purpose of this study is to investigate the clinical and microbiological effects of Bifidobacterium animalis subsp. lactis DN-173010 containing yogurt as an adjunct to non-surgical periodontal treatment in periodontitis patients. Materials and methods: This is a prospective randomized controlled clinical study registered with NCT05408364 under clinical trial registration. Thirty periodontitis patients were divided into 2 groups at random. As adjunctive to supra and subgingival instrumentation, the test group consumed Bifidobacterium animalis subsp. lactis DN-173010 containing yogurt while the control group consumed natural yogurt, once daily for 28 days. The plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) were recorded at baseline, 28th day, and 3rd month. Microbiological analysis was performed using culture method by obtaining subgingival plaque samples from 2 periodontal sites with 4≤PD≤6 mm at the same time points. Results: The inter-group comparisons of PI, GI, and BOP as well as the changes between the measurement time points were statistically significant in favor of the test group. There were no significant differences in terms of PD and CAL changes between the study groups at all times (∆baseline–28 days, ∆baseline–3 months) (p>0.05). The number of patients presenting subgingival Bifidobacterium species was significantly greater in the test group than the control group at the 28th day (p<0.05). Conclusions: The administration of probiotics has shown beneficial effects, albeit limited, on clinical and microbiological outcomes in the management of periodontitis patients. Clinical relevance: Daily consumption of probiotic yogurt may be supportive for supra and subgingival instrumentation.
