Objectives: Alginate impression commonly used in denture fabrication has drawbacks, which affects the quality of dentures. The objective is to determine the association between handling of alginate and denture quality. Materials and Methods: A structured questionnaire was administered to dental personnel, managing patients that required removable prosthesis in a multicenter cross-sectional pilot study. Information gathered were that of age, sex, number of teeth replaced, manipulation of impression material, disinfection of impression material, and quality of dentures. Likert scales were used to rate the participants' manipulation of alginate impressions and the quality of dentures. Statistical Analysis: Data were collated and analyzed with the Statistical Package for the Social Sciences version 20. Differences between categorical variables were tested for significance using Chi-square tests, and Student's t-test was used for means. A linear relationship between variables was tested using correlation statistics, and all statistical significance was inferred at P < 0.05. Results: Sixty-nine participants with a mean age of 27.00 ± 6.93 (20–57 years) took part in this study. The proportion of females seen was 55.1%. The mean number of dentures fitted was 10.03 ± 5.44, and 5.14 ± 2.71 dentures were relined annually. The most common partial edentulous case was Kennedy Class III (72.5%). There was a weak but insignificant positive association (r = 0.19, P = 0.12) between the quality of denture and handling of alginate impression material. There was also no significant correlation between the years of experience of the participants and scores for quality of denture (r = 0.02, P = 0.86) nor handling of impression by the participants (r = −0.07, P = 0.57). Conclusion: The participants' handling of alginate impression did not influence the quality of partial dentures made from them.
