Comparison of the Efficacy of Platelet-rich Fibrin and Connective Tissue Graft in Interdental Papilla Reconstruction

PT-IC was taken as the primary outcome measure. Normal distribution was assessed by histogram and Shapiro-Wilk test. Continuous variables were represented as mean±SD whereas the categorical variables were reported as numbers and percentages. Chi-square test was used for the comparison of the categorical variables. Since the data was normally distributed, Friedman test was used to analyze the time-dependent changes in both groups and the inter-group comparisons were made with Mann-Whitney test. Generalized Estimating Equation was used for analyzing qualitative and quantitative data, time-dependent changes, and the difference between two methods. Data analysis was performed in IBM SPSS Statistics Version 23, and p\<0.05 was considered as a significance threshold.
