NCT06452251

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • change from baseline to 3 months for IL10 and RANKL

    PICF and bone levels of markers were measured at baseline and at 3 months in both groups

    0 to 3 months

  • change from baseline to 3 months for RFA

    Measurement of primary and secondary implant stability were performed at baseline and at 3 months in both groups

    0 to 3 months

Study Arms (2)

vitamin D sufficient

Vitamin D sufficient group (Group S) \>20 ng/ml threshold was determined as sufficiency,

Diagnostic Test: OPG, OC, RANKL, IL-10, IL-1β, Ca, TNF-α and Caspase-1 ELISADiagnostic Test: Resonance Frequency AnalysisDiagnostic Test: Periodontal clinical examinationProcedure: Dental implant placement and bone sample collectionProcedure: Gingival Crevicular Fluid Sampling

vitamin d insufficient

Vitamin D insufficient group (Group IN-S) 12-20 ng/mol was determined as insufficiency.

Diagnostic Test: OPG, OC, RANKL, IL-10, IL-1β, Ca, TNF-α and Caspase-1 ELISADiagnostic Test: Resonance Frequency AnalysisDiagnostic Test: Periodontal clinical examinationProcedure: Dental implant placement and bone sample collectionProcedure: Gingival Crevicular Fluid Sampling

Interventions

The levels of OPG, OC, RANKL, IL10, IL1β, Ca, TNF-α and Caspase1 in bone and PICF of patients with or without Vitamin D sufficiency were measured by ELISA.

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.

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.

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).

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.

Sampling MethodNon-Probability Sample
Study Population

For the Vitamin D sufficient group (Group S) \>20 ng/ml threshold was determined as vitamin D sufficient, and Vitamin D insufficient group (Groups IN-S) 12-20 ng/mol was determined as insufficient. Vitamin D deficient patients (\<12 ng/ml), already using vitamin D supplements, were not included in the current study.

You may qualify if:

  • Being volunteer to participate in the study, For the Vitamin D sufficient group (Group S) having a vitamin D level \>20 ng/ml; and 12-20 ng/ml for Vitamin D insufficient group (Groups IN-S).
  • Having sufficient bone height and width at the edentulous areas, Not having a systemic disease that may adversely affect osseointegration, Not smoking Maintaining oral hygiene

You may not qualify if:

  • Vitamin D deficient patients (\<12 ng/ml), already using vitamin D supplements Presence of any systemic disease, such as uncontrolled diabetes, that may affect implant success, Smoking, Presence of untreated periodontitis, Previous exposure to radiotherapy in the head and neck area, Presence of osteoporosis or other metabolic bone diseases, Usage of oral/intravenous bisphosphonates, History of bone grafting and/or sinus lift, Long-term corticosteroid usage.
