        abstract = {Background: Continuous quality improvement (CQI) is essential for enhancing efficiency, patient safety, and care quality in dental practice. Although PDSA, Lean, and Six Sigma models are widely used in medical settings, evidence of their integrated application in private dental hospitals is limited. Aim: To evaluate the effectiveness of an integrated PDSA–Lean–Six Sigma framework in improving operational efficiency and patient satisfaction in a private dental hospital. Materials and Methods:A six-month mixed-methods study was conducted in a private dental hospital. Baseline data were collected for three months, followed by implementation of structured PDSA cycles supported by Lean tools and Six Sigma (DMAIC) analysis. Quantitative outcomes included patient waiting time, chairside utilization, staff efficiency, documentation error rates, and patient satisfaction scores. Qualitative data were obtained through staff interviews. Statistical analysis included paired t-tests, ANOVA, and process capability analysis (p < 0.05).Results:Mean patient waiting time decreased by 24.1% (28.6 ± 8.2 to 21.7 ± 6.9 minutes; p = 0.02). Chairside utilization and staff efficiency improved by 17.1% and 16.9%, respectively, while documentation errors declined by 36.7%. Patient satisfaction increased significantly (3.7 ± 0.8 to 4.4 ± 0.6; p = 0.02). Appointment processing sigma levels improved from 2.9 to 3. 6.. Conclusion:The integrated PDSA–Lean–Six Sigma framework is an effective and sustainable strategy for improving clinical efficiency and patient experience in private dental hospitals.},
