The high strength metal ceramic crowns have been extensively used in dentistry However, the fit is the most encountered problems in porcelain fused metal crowns. This mainly depends on the fabrication technique. The purpose was to compare the marginal fit of three techniques: direct laser metal sintering (DLMS) and milled wax with lost wax method (MWLW) and Conventional lost wax method. Thirty Cobalt-Chromium dies of dimension 5-mm height and a 0.5-mm chamfer finish line with a 12-degree angle of occlosal convergence. thirty dies were divided into three groups containing 10 samples each. All 30 dies were scanned using (Medit) scanner and data were used to fabricate metal copings using Laser sintering technique (Group-1), milled wax with lost wax method (Group-2) and Conventional lost wax method (Group-3). The study was done directly scanned under stereomicroscope at 50 x magnification for marginal fit evaluation. Differences in marginal gap were noted. Laser-sintered showed significantly smaller spaces between coping and abutment than milled wax/lost wax copings While the spaces was greater in the Conventional lost wax method. Laser-sintered Co-Cr crown copings showed better marginal fit than copings produced by milled wax/lost wax technique and Conventional lost wax technique.
Intracranial lipomas are a rare presentation in daily practice, representing <1% of all intracranial tumors. Lipomas of the corpus callosum are a subtype of intracranial lipoma. It is considered a rare type of tumor which accounts for less than 0.1% of brain tumors and less than 0.08% of tumors found on autopsy. They may present as headache, seizures, local mass effect or may be found by chance as they are asymptomatic in half of the cases. We reported a case of corpus callosum lipoma which was incidentally found in a 5-year-old girl who presented with seizure for the first time.
Chronic wounds are type of wounds that do not heal in an expected period of time, they are challenging to treat and pose a threat for the afflicted. Platelet-rich plasma has the potential in overcoming these challenges as it is typically used in accelerating healing. This systematic review was conducted in accordance to the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis (PRIMSA). 6 out of 345 records were selected for this review. The administration of platelet-rich plasma to patients caused an increased rate in chronic wound healing process as seen from the differences in the wound size. Based on the data gathered, AA-PRP is considered safe and effective in aiding the process of chronic wound healing.
Health education is important to know by community to better action in health habit. Several studies related to the comparison of the results of online and offline education have found mixed results, so in this study find out the differences in the results of online and offline education at Mafatihul Huda School, Cirebon, and find best method for conducting health education. This study used 4 treatments, posters and voice notes (POV), power points and voice notes (PPV), videos (VID), and offline (OFL). Total sample is 122 respondents. Subject groups POV 29 respondents, PPV 27 respondents, VID 33 respondents, OFL 33 respondents. Data in this study were collected at the time before and after the intervention and used a questionnaire instrument. In the questionnaire there are 10 questions related to knowledge about health including healthy lifestyle, balanced nutrition, and functional food. There were significant differences in the pre and post test values for the poster & voicenote (p=0.043), video (p=0.001), and offline (p=0.001) methods, but there were no significant differences in the pre and post test scores for the power point & voicenote method (p=0.362). In the poster & voicenote, video, and offline methods there is no significant difference in the difference between the pre and posttest scores of the 3 methods (p=0.054). The poster & voicenote, video, and offline methods have the same effectiveness in increasing respondents' knowledge about health education.
