Statement of problem: Denture induced traumatic mucosal ulcerations appear most often after placement of new denture, despite careful attention to detail in the fabrication of complete dentures. The ulcerations may be more common in some particular denture bearing areas, indicating that it is necessary to evaluate the prosthesis to make adjustments at delivery stage and subsequent adjustment appointments.
Purpose: Determine the ratio of patients requiring denture adjustments following placement of denture with and without the use of pressure indicating media.
To evaluate the ratio of maxillary and mandibular denture induced irritation.
Materials and method: This in vivo study was conducted to evaluate and compare the frequency and location of traumatic ulcerations following placement of complete denture with and without the use of pressure indicating paste. 26 patients were enrolled in the study, 13 patients in each of the two groups - In test group (A) pressure indicating paste was used during denture insertion and post insertion adjustment appointments. In control group (B) pressure indicating paste was not used during insertion and review appointments. The results were analyzed for statistical comparison and significance by using ‘z’ test. A Statistical package SPSS 13.0 (Microsoft version, Chicago) software was used for statistical analysis. A value of p< 0.05 is considered to be statistically significant.
Results: Significantly higher number of mucosal ulcerations in control group as compared to the test group at each adjustment visit. The results also revealed greater number of mucosal ulcerations in the mandibular denture bearing areas as compared to the maxillary denture bearing areas. These ulcerations reduced during the subsequent adjustment visits with higher number of ulcerations observed in the control group as against the test group.
Conclusion: Greater incidence of denture adjustments were required in patients where pressure indicating paste was not used. Therefore use of pressure indicating medium should become a routine procedure.
