Abstract Aim: The aim of the present study was to evaluate the clinical and radiographic effectiveness of Non- Incised Papilla Surgical Approach (NIPSA) compared to Modified Minimally invasive surgical technique (M-MIST) in the treatment of periodontal intraosseous defects in stage III periodontitis patients as: primary outcome: Clinical assessment for clinical attachment level (CAL) following surgeries for both groups and secondary outcome: Clinical assessment related to reduction in probing pocket depth (PPD), amount of gingival recession (GR) and radiographic bone fil. Methodology A total of thirty- two intra-osseous defects in 15 patients suffering from Stage III Periodontitis, participated in this randomized clinical trial (RCT) without any drop- out. The patients were divided into two groups with 16 intra-bony defects each. (N=16 patients per each group): group I (Test group) was received Non-Incised Papilla Surgical Approach (NIPSA), while, group II (Control group) was received Modified Minimally Invasive Surgical Technique (M-MIST). All the clinical parameters assessed at baseline and 1 year follow up period. In addition, radiographic parameters assessed during the same follow up period using standardized digital periapical individualized Extension Cone Paralleling (XCP) index for each patient. All data was collected, checked, revised, tabulated and entered into the computer. Statistical analysis was performed and data were explored for normality using Kolmogorov-Smirnov and Shapiro-Wilk tests. For non-parametric data: Mann Whitney test was used to compare between two groups in non-related samples. Friedman test was used to compare between more than two groups in related samples. Wilcoxon test was used to compare between two groups in related samples. For parametric data: Independent sample t-test was used to compare between two groups in non-related samples. Repeated measure ANOVA was used to compare between more than two groups in related samples. Paired sample t-test was used to compare between two groups in related samples. viii Spearman correlation was used to find the correlation between different parameters. Results: Statistically significant difference in PD, CAL, RH, Gingival bleeding score, radiographic defect fill and post-surgical patient satisfaction were noted for each groups at different time periods. However, all clinical and radio graphical parameters revealed intergroup non statistically significant differences for both groups. Conclusions: Within the limitations of the present study, we can conclude that minimal invasive surgical techniques considered the best treatment modalities in improving clinical and radio graphical parameters and also patient centered outcome |
