A sample size of 285 subjects (95 cases and 190 controls) was enrolled in the study. Anamnestic questionnaire was administered to the patients fulfilling the criteria. Based on the score attained, patients were grouped as TMD patients (case) or TMD free patients (control). A pre-designed performa was used to record the data. SPSS v.17.0 was used for descriptive and inferential analysis. RESULTS: The mean age of the participants was 33.3±11.2 years with male to female ratio of with 1.26:1. Maximum of the participants (72%) were of 41 years or less. Overall mean number of missing teeth in all participants was 3.41±3.08. Mean number of missing teeth in cases and controls was 4.46±3.65 and 2.89±2.60 respectively (p< 0.001). Tooth loss of <5 teeth & ≥5 teeth was observed in 53 & 42 cases as compared to 128 & 62 controls respectively (OR=0.61; 95% CI: 0.36 to 1.01; p-vale 0.056). The relationship for number of quadrants with number of missing teeth in cases and control groups was significant (p-value=<0.001). CONCLUSION: Present study indicates that there is significant correlation between the numbers of quadrants with tooth loss and TMD. Increasing the number of quadrants with tooth loss will increase the risk of TMD. However, the number of teeth lost itself has no association with TMD.
Objectives: To compare satisfaction levels of patients wearing maxillary completes denture fabricated by closed mouth and an open mouth impression techniques. Methods: This Comparative clinical study was conducted at the Department of Prosthodontics, Armed Forces Institute of Dentistry (AFID), Rawalpindi. Eighty-four edentulous patients were included in this study; the patients were randomly allocated into two groups. Group A patients were provided with dentures fabricated by closed mouth impression technique and Group B patients were provided with dentures fabricated by open mouth impression technique. The patient’s satisfaction level was assessed after six weeks of denture insertion with a questionnaire attached as Annex-A. Results: Out of 42 patients in group A, 12 were highly satisfied, 28 moderately satisfied and 2 poorly satisfied. In group B patients, 9 were highly satisfied, 25 moderately satisfied and 8 poorly satisfied. Retention was highest (81.0%) in patients of group A compared to group B (19%). Moderately satisfied patients were more significantly (p=0.04) more (69.0% in group A and 71.4% in group B) comfortable compared to highly satisfied (26.2% in group A and 19.0% in group B) and poorly satisfied (4.8% in group A and 19.5% in group B) in both groups. There was no statistically significant difference among patients in both groups when their satisfaction with their ability to chew with dentures was compared. Regarding satisfaction with speech ability more patients were moderately satisfied (28.6% in group A) compared to the number of patients (21.4%) in group B. Overall, 70.2% of moderately satisfied category showed significantly higher frequency of patients followed by 17.9% patients each lying in highly satisfied and poorly satisfied patients, categories. Clinical implication: Final impression in complete denture (CD) fabrication is very crucial step that can affect overall prognosis of CD treatment and therefore, patient satisfaction with CDs. A simplified closed mouth impression approach to complete denture treatment, omitting the border molding and definitive impression appointment, has been suggested as an alternative to the conventional open mouth approach. Conclusion: Dentures fabricated by closed mouth impression technique are more stable and functionally better compared to those constructed by open mouth impression technique.

OBJECTIVE: To compare the flexural strength of maxillary denture bases made in high impact and conventional heat cure acrylic resin. METHODS: This experimental laboratory-based study was conducted in Peshawar Dental College, Materials Research and Centralized Resource Laboratories University of Peshawar, Pakistan. Total 120 edentulous maxillary casts, sixty each of conventional acrylic (30 in subgroup-IA for shallow palate and 30 in subgroup-IB for deep palate and high impact acrylic (30 in subgroup II-A for shallow palate and 30 in subgroup II-B for deep palate) were made. These were then tested for flexural strength using universal testing machine. The load was applied at the rate of 5.0 mm/min. Independent samples t-test was applied for statistical analysis. RESULTS: Mean values of deflection at fracture, fracture load and flexure strength were 0.309±0.059 cm, 87.729±22.497 Kg and 13.645± 4.453 kg/cm² respectively. Mean Flexure Strength (kg/cm2) was 8.30±1.27, 16.54±1.77, 10.88±1.01 and 18.85±1 in subgroups I-A, I-B, II-A and II-B respectively (<0.001). Mean deflection at fracture (cm) was 0.24±0.04, 0.29±0.03, 0.35±0.03 & 0.368±0.03 in subgroups I-A, I-B, II-A and II-B respectively (<0.001).Mean Fracture Load (Kg) was 69.97±3.12, 114.9±6.75, 63.28±7.05 & 102.8±5.5 in in subgroups I-A, I-B, II-A and II-B respectively (<0.001).CONCLUSION: High impact acrylic resin was found to have significantly higher flexure strength as compared to conventional acrylic resin
