OBJECTIVES Stereognosis has been investigated occasionally to predict the prognosis of treatment with complete dentures. This study evaluated oral stereognosis and satisfaction levels in completely edentate patients wearing prostheses for at least three months. METHODOLOGY From November 2014 and January 2016, data from 322 patients' follow-up visits were collected from records of the Prosthodontics department at Liaquat University of Medical and Health Sciences, Jamshoro. Denture satisfaction was assessed using a self-structured proforma, and oral stereognosis was measured using different-shaped objects made from self-cure acrylic resin, kept in the oral cavity without showing them to the patient. The frequency of qualitative variables was determined for data analysis, and a chi-square test was applied. Significant P-values were defined as those less than 0. RESULTSThe male-to-female ratio was 1.2:1, with 50.9% wearing a prosthesis for less than a year and the minimum range being 3-6 years (13.66 %). Only 31 had stereognosis positive but were completely satisfied with their prosthesis, while 85 who were unsatisfied were found to have positive sensory perception. Statistical analysis for all groups shows a p-value of 0.000 for patient satisfaction with denture wear which is statistically significant. Most patients with the least duration of wear found their stereognosis positive and were unsatisfied with the prosthesis and vice versa. The chi-square test shows a statistically significant value for both groups of stereognosis i-e 0.0001.. CONCLUSION Patients with the shortest period of wear were found to be more dissatisfied, but their oral perception remained intact, while those with more experience complained less but had reduced stereognosis.

Aim: To compare the rise in temperature inside pulp chambers with two different provisional crown prosthesis materials. Study Design: Comparative -in vitro. Place and Duration of Study: Department of Prosthodontics, Liaquat Medical University Hospital from AUGUST 2019 TO DECEMBER 2019. Methodology: The purpose of this study was to evaluate the mean rise in temperature during provisional restoration utilising Polymethyl methacrylate resin (PMMA) versus bis- glycidyl methacrylate resin (Bis-GMA) at in-vitro laboratory of Prosthodontic department, Liaquat University of Medical and Health, Jamshoro. A total number of 60 extracted maxillary central incisor teeth were selected using non probability consecutive sampling technique. Teeth were divided into two groups on the basis of fabrication material used. In group I; Poly-methyl methacrylate resin (PMMA) was used for provisional restoration and in group II; bis-glycidyl methacrylate (Bis-GMA) was used for provisional restoration. Tooth preparations were performed following all the principles. Mean temperature rise was recorded and compared for both material over each tooth using radicular approach after placing the provisional restorations in impression mould. Results: A total number of 60 teeth were selected, out of which 31 (51.67%) were right maxillary central incisor and 29 (48.33%) were left maxillary central incisor. On comparison of mean rise in pulp temperature between the PMMA group and Bis-GMA group, mean rise in temperature was significantly high in PMMA group; 40.59±0.56°C versus 39.40±0.53°C in Bis-GMA group (p-value <0.0001). Conclusion: The mean rise in pulp temperature using Bis-GMA resin was significantly less as compared to the PMMA material. So Bis-GMA should be preferred over PMMA material for provisional restorations.

Background: Use of the smokeless tobacco is a major public health problem. Oral mucosal hyper keratinization occurs due to smokeless form of tobacco. Objective: To determine the Submandibular Gland injuries induced by smokeless tobacco in Albino Rat. Study Design: Experimental study.

Aim: To determine closest speaking space in different Angle’s malocclusion classes. Study design: Descriptive Cross Sectional. Place and Duration of Study: .Department of Prosthodontics, Liaquat University of medical and Health Sciences Hospital during period of July 2021 - Dec 2021. Methodology:Total  111  Patients  from  both  genders  with  age  range  18-45  with  intact  1st  and  2nd premolars were alginate impressions were taken. Polysiloxane Elastomeric impression material bites in 1.5cm thickness were placed bilaterally on occlusal surfaces of mandibular premolars and molar teeth in patients oral cavity. Patients were instructed to swallow and repeat the Sindhi Language word “SASSI”. The elastomeric material bite blocks were removed and thickeness was noted down for each patient at premolar region using digital vernier calliper. The measurements were recorded in millimetres. Results: A total of 111 patients were examined, with an average age of 35 years and a range of 18 to 45 years (Table 1). Males made up 56 % of the population, while females consists of 44 % (Figure 1). According to occlusion, the majority of patients had class I 50 (45 %), class III 29 (26.1 %), and class II div I and II 16 (14.4 %) correspondingly (Table 2). According to the mean closest speaking space, it was highest in class II div II 7.05+2.38 mm and  in class II div I 4.81+3.47 mm, with 2.02+0.75 mm in class I and 1.20+1.08 mm in class III (Table 3). Conclusion: It was concluded that closest speaking space was significantly increased in angles class II patients whereas decreased in angles class III.
