Abstract : ABSTRACT To investigate and compare the changes in retentive forces and wear resistance of two attachment systems Nova-loc& telescope with different design and overlaying patrices over two un splinted implant supported mandibular over denture under short-term simulated function. Two models carrying a two-implant analogue with two different types of overlying patrices Telescope and Nova loc over which an acrylic complete denture was constructed with picked up corresponding matrices. The tensile forces were applied using a universal testing machine to evaluate retention force, and digital microscope was utilities to evaluate wear resistance. Evaluation of retentive force & wear resistance of telescopic and Nova-loc IODs was carried out at five-time intervals; at baseline and after they are subjected to cyclic loading under at 500, 1000, 1500 and 2000 cycles of repeated insertion and removal. Retentive values were recorded by using independent t-test which revealed the retention of the group I (Telescope) was significantly higher (p<0.05) than those of group II (Nova loc) at baseline & after exposure to different cyclic loading (500- 1000- 1500- 2000). Regarding the wear, comparison of wear (wear change) of both groups was performed by using t-test between mean difference which revealed that the group I (telescope) was significantly higher than group II (Nova-loc). Regarding to Telescope and Nova-loc systems have satisfactory retentive forces, However, short-term successful clinical use in implant overdentures. Nova loc attachments are promising to be successfully used in implant overdentures as the Telescopic coping attachments with satisfactory retention. However, the retention value of Telescope higher than Nova loc, the wear behavior of Nova-loc lesser than Telescope due to the peek material.

Abstract : ABSTRACT This study aims to compare the retention and wear changes between two stud attachments “Locator” and “Novaloc” used for implant supported mandibular overdenture. Two ready-made epoxy resin models represented completely edentulous patients were prepared to receive two implant analogues in the canine area and divided randomly into two groups. The first group represented the Locator attachment with its nylon matrix and metal housing; the second one was Novaloc with its PEEK matrix. Two overdentures were constructed for each group. The pick-up proceeded as conventional method. Universal testing machine was used to measure the retention of each attachment. Chewing simulator exerted multiple cycles mimicking the insertion and removal of the overdentures at the baseline, 500 cycles, 1000 cycles, 1500 cycles and 2000 cycles. Digital microscope was used to evaluate the wear behavior of each attachment during these different cyclic loading. Regarding retention was performed by using Independent t-test which revealed that retention of group I (Locator) was significantly higher (P<0.05) than group II (Novaloc) at baseline, 500 cycles, 1000 cycles, 1500 cycles and 2000 cycles. Comparison between mean difference of wear (wear changes) of both groups was performed by using Independent t-test which revealed in the overall changes group I (Locator) was significantly higher than group II (Novaloc). The Locator showed higher initial retention than Novaloc. Regarding wear behavior, Novaloc showed lesser wear and changes than Locator attachment.

Abstract : Background: Diabetes mellitus is becoming extremely prevalent in India and other developing countries. Diabetes consequences, such as long-term cardiovascular, renal, neurovascular, and retinal problems are primary contributors of disability and mortality, necessitating screening. Objective: To describe the screening strategies of long-term complications amongst patients with diabetes attending a tertiary care out-patient facility. Method: A cross- sectional quantitative analysis was performed using patient’s clinical records. A random sample of 120 individuals with diabetes who consulted the hospital was chosen randomly. The results of the dilated eye, foot and dental examination, urine analysis, cholesterol profile, other associated comorbidities along with demographic data were all extracted. Data was collected and descriptive analysis was performed using Microsoft Excel. Results: The following screening tests were consistently prescribed to be performed: HTN, eye care, foot care, dental care, vaccines, smoking cessation and alcohol cessation. Out of the patients recommended with screening tests, 100% of patients underwent screening for HTN followed by 20% of patients underwent screening for eye care, 38.80 % patients underwent screening for foot care, 14.28% patients for dental care and none of the patients for vaccines, smoking and alcohol cessation. All the patients had their HbA1c tested and highest proportion of patients with abnormal results were found which could eventually lead to long- term side effects. Conclusion: In most individuals, screening for long-term consequences of diabetes mellitus was inadequate, and incorrect documentation of results were common. Screening techniques need to be improved.
