Although clinician's skills and experience play a major role in designing and fabrication of the optimum prosthodontic restorations, the selection of denture resins is equally important, especially when the patient has been using the prostheses since long. Eighteen cases who were not satisfied with their conventional acrylic dentures were selected. They were provided flexible dentures along with a questionnaire to precisely evaluate the advantages of new material. Prosthodontic planning & observations regarding this material are discussed on various parameters.

Background: Patients using single maxillary denture against their natural mandibular teeth face the problem of midline fracture in their routine acrylic dentures. Various techniques have failed over the years to address the problem. In this study, flexible denture material (Lucitone) with injection moulding system has been used and evaluated for midline fracture in these patients. Methods: A total of 58 patients in the age group of 38 to 80 years, who had experienced midline fracture in their acrylic maxillary dentures were selected. They were provided with new dentures using flexible denture material. Various parameters, namely, mastication, phonetics, esthetics and comfort level were evaluated. Result: Only two cases reported slight crack in the palatal region of the maxillary dentures after 18 months of use. Mastication and phonetics were found to be improved with flexible dentures. Conclusion: The flexible denture is a promising material for preventing midline fractures in a single maxillary denture. It is well tolerated by the patients as compared to the methyl meth-acrylate dentures.

Primary iron overload in Indians is non-HFE type, which is different from that in Europeans and further molecular studies are required to determine the defect in various iron regulatory genes.

Short term therapeutic efficacy of oral appliances therapy in non-apneic snoring and OSA cases was observed.

Background & aims: Minimal hepatic encephalopathy (MHE) has significant impact on future clinical outcomes, such as occurrence of overt HE (OHE) and survival in patients of cirrhosis. In the absence of a 'gold standard', psychometric hepatic encephalopathy score (PHES) is widely used for the diagnosis of MHE. This cross-sectional and prospective study was carried out to determine the usefulness of inhibitory control test (ICT) for the diagnosis of MHE. Methods: One hundred and two patients with cirrhosis and without a history of OHE were enrolled in to the study and were subjected to PHES and ICT. MHE was diagnosed when the PHES was # À5. ICT was considered abnormal when the numbers of ICT lures were more than 14. Results: Forty-one (40.2%) patients had MHE. There were 40 patients with normal PHES and ICT, 32 with abnormal PHES and ICT, 9 with abnormal PHES and normal ICT, and 21 with abnormal ICT and normal PHES score. ICT had 78% sensitivity and 65.6% specificity and an areaunder-the-curve value of 0.735 (95% CI = 0.632-0.830) for the diagnosis of MHE. In patients with cirrhosis, ICT did not correlate with severity of liver disease as measured by CTP score (r = 0.044, P = 0.658) and MELD score (r = 0.176, P = 0.077). ICT did not predict survival as well as PHES; while 6 (11.3%) patients died among those who had altered ICT compared to 4 (8.2%) patients who did not have altered ICT (P = 0.74), 8 (19.5%) patients died among those who had altered PHES compared to 2 (3.3%) patients who did not have altered PHES (P = 0.013). Conclusion: ICT is not as useful as PHES in diagnosing MHE in patients with cirrhosis of the liver. It does not correlate with disease severity and predict survival as well as PHES.
