Does Caffeine Affect Dental Implant Stability? A Prospective Cohort Study
Abstract
Statement of the Problem: Caffeine intake affects bone metabolism through inhibition of osteoblast proliferation. Purpose: This study aims to assess the effect of caffeine consumption on implant stability in the healing period of patients. Materials and Method: A prospective cohort study is designed to assess implant stability in the posterior of the maxilla. Patients were divided into two groups based on daily caffeine intake as group 1 with consumption of 400 mg/daily caffeine or more, and group 2 with consumption of 100 mg/daily caffeine or less. The implant stability was measured by resonance frequency analysis (RFA). The mean implant stability quotients (ISQs) were calculated. RFA measurements were made at 4, 6 and 8 weeks after implant placement. Results: A total of 102 patients were studied (51 in each group). The mean of ISQ was 43.49± 2.32 in the group 1 and 42.78±2.34 in the group 2 at four weeks after insertion. The mean of ISQ was 50.86±3.06 in group 1 and 51.37±2.44 in the group at six weeks after implant placement. At eight weeks after implant surgery, the mean of ISQ was 56.78±3.77 in the group 1 and 57.84±1.82 in the group 2. The mean of ISQ between the two groups at 4, 6 and 8 weeks after implant placement was not statistically different. (p= 0.13, p= 0.36 and p= 0.08 respectively) The repeated measure test indicated a similar increase in ISQ in various study times in the two studied groups (p=0.47, df=1, F=0.52). Conclusion: Acquired data suggest that…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 102 participants or records.
