Clinical Trial Summary

Vitamin D is important for bone health, immune function, and inflammation, along with dental implant success. The study aimed to assess bone markers and cytokine levels in patients with and without vitamin D insufficiency to better understand the effects of vitamin D levels on dental implant integration. The study included 42 patients in 2 groups; with insufficient (Group IN-S; n=21) and sufficient (Group S; n=21) levels of vitamin D. Bone remodelling, proinflammatory and antiinflammatory markers were analyzed in bone and peri-implant crevicular fluid (PICF) using enzyme-linked immunosorbent assay (ELISA) and results were reported as concentration and total amount.

Description:

Background: Vitamin D is crucial for bone mineralization and plays a significant role in immune and inflammatory responses. Its deficiency is highly prevalent and might alter osseointegration of dental implants. Since successful osseointegration is a critical aspect of implant survival and the effects of vitamin D on implant osseointegration have not been well documented, the aim of this study was to evaluate bone markers and cytokine levels of patients with or without vitamin D insufficiency. Methods: A total of 42 patients were included and divided into two groups: Vitamin D insufficient (Group IN-S; n=21) and Vitamin D sufficient (Group S; n=21). Besides clinical periodontal parameters and implant stability measurements, bone and peri-implant crevicular fluid (PICF) levels of Receptor Activator of Nuclear Factor Kappa B Ligand (RANKL), osteoprotegerin (OPG), osteocalcin (OC), calcium (Ca), tumour necrosis factor alpha (TNF-α), Interleukin 1β (IL-1β), caspase-1 and Interleukin 10 (IL-10) were determined by enzyme-linked immunosorbent assay (ELISA). Results were represented as concentration and total amount.

• Osseointegration Failure of Dental Implant
• Peri-Implantitis
• Vitamin D Deficiency

Intervention

Diagnostic Test:
• OPG, OC, RANKL, IL-10, IL-1ß, Ca, TNF-a and Caspase-1 ELISA
The levels of OPG, OC, RANKL, IL10, IL1ß, Ca, TNF-a and Caspase1 in bone and PICF of patients with or without Vitamin D sufficiency were measured by ELISA.
• Resonance Frequency Analysis
Implant stability was measured by a device (Penguin RFA, Integration Diagnostics, Sweden) based on Resonance Frequency Analysis (RFA) and categorized by Implant Stability Quotient (ISQ) scale.
• Periodontal clinical examination
Clinical periodontal indices including plaque index (PI) (Silness and Löe 1964), gingival index (GI) (Löe 1967), probing depth (PD), and bleeding on probing (BOP) (Ainamo and Bay 1975) were recorded using a Williams periodontal probe. The BOP percentage (%) was calculated by dividing the number of bleeding sites by the total number of sites examined.

Procedure:
• Dental implant placement and bone sample collection
All patients were received by a single examiner a bone level implant (standard type and Sandblasted, Large-grit, Acid-etched surface) (Implant Swiss, Yverdon, Switzerland).
• Gingival Crevicular Fluid Sampling
One month after the healing caps were inserted, peri-implant crevicular fluid (PISF) samples were collected from 6 different sides of each implant. Before sampling, the area was isolated and dried, and paper strips were gently kept in periimplant sulcus for 30 seconds. Strips with blood or saliva contamination were discarded. PISF volumes of each strip were measured by a device (Periotron 8,010, Oraflow Inc, USA). Strips were then pooled, and inserted into tubes. PISF was recovered from paper strips through agitation in phosphate buffer saline (50 mM Tris-HCl, 5 mM CaCl2, 0.2 M NaCl,pH 7.5). All samples were stored at -80C until the day of analysis.
