Distribution of Microbial Plaque on Intaglio Surfaces of Maxillary Removable Complete Denture: A Cross Sectional Study

Aim: To assess the dispersion of prosthetic microbial plaque on intaglio planes of removable completely edentulous denture.

Study Design: Descriptive Cross Sectional

Place and Duration of Study: Department of Prosthodontics, Liaquat Medical University Hospital from December 2107 to November 2018.

Methodology: The maxillary removable complete dentures were collected from the 62 patients. The inner sides of the maxillary prosthesis remained revealed with 1% neutral red solution. These internal sides stayed at that point captured with an advanced camera. Natural plaque scattering on the inner layer of the denture was inspected by calculating plaque layering the subsequent definite zones of the denture inner layers: The fitting layer of the maxillary prosthesis was divided into 14 zones. Biofilm was enumerated in all of the 14 assessed zones by a visual analogue scale. The data was analyzed by SPSS version-16. Independent t test and Anova test were applied for statistical difference of plaque score.

Results: Males and females were 48% and 52% respectively. The mean age was 56.48 ± 7.176. The mean plaque score on intaglio surface was 1.912 ± 0.468. The Vestibular inclination of the right labial flange (areas 4) had the highest biofilm growth 19% tailed by palatal inclination, frontal portion of the right buccal flange (area 8) 18%, vestibular inclination of the left labial flange (area 3) 14% and palatal inclination, front portion of the left buccal flange (area 11) 11%. There was no statistical difference between gender and plaque score.

Conclusion: The Vestibular slope area of the right labial flange had the greater growth of plaque shadowed by Palatal slope space, frontal zone of the right buccal extension area, Vestibular slope area of the left labial extension and slope of palate area, front zone of the left buccal extension.
