Background: There are many causes and reasons associated with fractures of complete dentures. The present study assessed case of complete denture fracture. Materials and Methods: One hundred and fifty complete denture wearers reported to the department of prosthodontics for correction of complete denture fracture were examined carefully. The factors such as retention, stability, and occlusal errors were recorded. Cause of denture fracture was recorded too. Results: Out of 150 patients, males were 80 and females were 70. The site of fracture was incisor area in 25, canine area in 30, midline in 50, molar area in 10, and maxillary tuberosity/retromolar pad area in 35 cases. The etiology of denture fracture was accidental fall in 42, poor fit in 28, poor occlusion in 40, material breakage in 25, and acrylic base defect in 15 cases. The difference was statistically significant (P < 0.05). Conclusion: Most common cause of denture fracture was accidental fall, poor fit, poor occlusion, and material breakage.

In extreme cold weather clothing ensemble, multiple layers of high bulk nonwovens are used to provide thermal insulation to the wearer. In this work, the effect of layering sequence in multi-layered high bulk thermal bonded nonwoven assembly on its thermal resistance is evaluated experimentally under sub-zero temperatures. Two multi-layered nonwovens, one made up of 1.4 denier solid (1.4 D S), 6 denier hollow (6 D H) and 15 denier hollow (15 D H) and the second made up of 3 denier hollow (3 D H), 6 denier hollow (6 D H) and 15 denier hollow (15 D H) polyester fibres were studied. The experiments were performed in a climatic chamber in the temperature range of 310 K to 210 K. Numerical simulations were carried out assuming heat transfer through the nonwovens as one-dimensional coupled conduction-radiation. The numerical methodology was developed using theoretical relations available in the literature to estimate the steady-state temperature profiles through the nonwoven layers and were validated using experimental data. The concurrence of experimental and numerical temperature profiles justifies the numerical methodology adopted in this work. Thermal resistance provided by the high bulk nonwoven increases with a decrease in ambient temperature. It is found that the thermal conductivity of nonwoven layers decreases from inner-to outer layers at a given ambient temperature. The heat flux through nonwoven layers, overall thermal conductivity and the thermal resistance of multi-layer nonwoven are independent of layering sequence if the convective heat transfer is extremely low.

Background: Periodontitis is a chronic inflammatory disease of multifactorial etiology. The present study was conducted to assess the effect of periodontal and prosthodontic therapy on glycemic control in patients with diabetes. Materials and Methods: 80 type II diabetics patients of both genders were divided into Group I (periodontal and prosthodontic therapy) and Group II (Healthy). In control group, only oral hygiene instruction and mouth wash were prescribed. Results: Group I had 22 males and 18 females and Group II had 17 males and 23 females. The mean glycated hemoglobin level in Group I was 7.8% before and 6.7% after treatment and in Group II was 6.4% before and 6.2% after treatment. The difference was significant (P < 0.05). Conclusion: There was improvement in glycemic status in diabetic patients undergoing periodontal and prosthodontic therapy as compared to those not undergoing treatment.
