Main Article Content
Abstract
Introduction: Zinc Oxide Eugenol (ZOE) and silicone are among the most widely used materials, each offering distinct advantages and limitations. ZOE. The objectives of the present study were to compare the effectiveness of ZOE and silicone impression materials in complete denture fabrication with respect to denture retention, stability, support, post-insertion sore spots, and oral health-related quality of life. Methodology: A randomized controlled trial was conducted among 20 completely edentulous patients (ACP Class I and II). Participants were randomly assigned to ZOE or silicone groups (n=10 each). Outcomes were assessed after two weeks using a 5-point Likert scale, clinical evaluation of sore spots, and OHIP-EDENT questionnaire. Data were analyzed using Mann–Whitney U and Fisher’s exact tests (p < 0.05). Results: No significant differences were found between the groups in retention, stability, support, sore spots, or OHRQoL (p > 0.05). Conclusion: ZOE and silicone impression materials demonstrated comparable clinical performance and patient satisfaction in complete denture fabrication.
