| Summary: | Background:
Peri-implant soft tissue health is crucial for the long-term success of dental implants. Patients with systemic conditions, such as diabetes mellitus and cardiovascular diseases, are at higher risk for peri-implant complications. This study aimed to assess the cellular responses of peri-implant soft tissues in vitro, simulating conditions influenced by systemic diseases, to better understand the potential impact of these conditions on implant success.
Materials and Methods:
An in vitro study was conducted using human gingival fibroblasts exposed to simulated inflammatory conditions representative of diabetes (high glucose environment) and cardiovascular diseases (increased proinflammatory cytokines). Titanium discs with treated surfaces were used to mimic implant surfaces. Cellular proliferation, adhesion, and cytokine expression were evaluated using MTT assay, fluorescence microscopy, and ELISA, respectively. Experimental groups included Group 1: Healthy control, Group 2: High-glucose condition, Group 3: Proinflammatory cytokine condition, and Group 4: Combined high-glucose and proinflammatory cytokine condition.
Results:
Fibroblast proliferation rates were significantly reduced in Groups 2 (50%) and 3 (55%) compared to Group 1 (85%). Adhesion strength was also compromised in Groups 2 (60%) and 3 (65%), with the lowest observed in Group 4 (40%). Cytokine analysis revealed elevated levels of IL-6 and TNF-α in Groups 3 (IL-6: 150 pg/mL, TNF-α: 200 pg/mL) and 4 (IL-6: 180 pg/mL, TNF-a: 250 pg/mL) compared to the control (IL-6: 50 pg/mL, TNF-α: 60 pg/mL).
Conclusion:
Systemic conditions significantly impair peri-implant soft tissue cellular responses, including proliferation, adhesion, and inflammation regulation. These findings underscore the importance of tailored peri-implant management strategies for patients with systemic diseases to ensure implant longevity. |
