Abstract:

Introduction. Denture-induced traumatic mucosal ulcerations appear most often after the placement of a new denture, despite careful attention paid to details in the fabrication of complete dentures. Aim. Determination of the ratio of patients requiring denture adjustments following the placement of denture with and without the use of pressure indicating media and evaluation of the ratio of maxillary and mandibular denture-induced irritation. Materials and methods. An in vivo study was conducted to evaluate and compare the frequency and location of traumatic ulcerations following the placement of complete denture with and without the use of pressure indicating paste. 26 patients were enrolled in the study, 13 in each of the two groups considered for the study. 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 the ‘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 statistically significant. Results and discussion. A significantly higher number of mucosal ulcerations was observed in the control group, compared to the test group, at each adjustment visit. The results also revealed more numerous mucosal ulcerations in the mandibular denture bearing areas, compared to the maxillary denture bearing areas. These ulcerations were reduced during the subsequent adjustment visits, compared to the higher number of ulcerations observed in the control group as against the test group. Conclusions. A higher incidence of denture adjustments was observed in patients in whom pressure indicating paste was not used. Therefore, the use of a pressure indicating medium should become a mandatory procedure.
