Filter by:The study team is inviting 13 healthy people to complete a study to explore how calcium affects hormones and bones after eating. Participants will be asked to complete two study visits within eight weeks. Before each visit, participants will be asked to not eat or drink (except water) for 9 hours. At each visit, participants will eat the same meal provided by the research team. Along with their meal, they will take a pill - in one session, this will be a calcium supplement, and in the other, a placebo (a pill with no calcium), but they won't know which one they are taking at which session. A phlebotomist will draw blood before the meal and pill, then again several times after eating. Blood draws will take place over three hours. During that time, participants will complete questionnaires about health, diet, and physical activity. Blood will be analyzed to check on various health indicators, like bone health markers and certain hormones, to see how they change after the meal. The difference in these health indicators between the calcium and placebo sessions will help the study team understand the impact of calcium on health after eating. This could help increase knowledge of the impact of calcium on hormones and bone health.
split-mouth RCT, 25 months follow up. GBR protocol with LPRF as grafting material in the test group and autogenous bone with DBBM as grafting material in the control group.
The goal of this clinical trial is to evaluate the safety of placing TiO2 scaffolds in alveolar ridge and to evaluate if the scaffold material contributes to maintain the anatomy and the volume of the alveolar process after tooth extraction.
The investigators recruited 32 diabetic IOD patients with a total of 110 problematic implants who had completed the treatment for peri-implantitis between January 2021 and March 2023 as research subjects. The patients were randomly assigned to the control group or the experimental group using the random number table. The control group received routine postoperative medical advice, whereas the experimental group was given an IMB model-based continuity of care.
Sinus floor elevation (SFA) and GBR have been applied in the placement of dental implants in longstanding edentate posterior maxilla region. However, the number of study on the efficacy of these procedure on areas with 0mm bone height is limited. This case study aims to compare two cases of 0mm bone height in the posterior maxillae region with different handling procedure. In this article, two female patients in their 40s underwent maxillary sinus augmentation (sinus lifting) due to longstanding missing posterior maxillary molars with the bone of which area had resorbed entirely, leaving 0mm bone height. One patient went through conventional sinus augmentation while the other had a two-stage - sinus - lift procedure. Researchers compared the bone - volume induced between the two procedures.
The aim of the present study was to compare the half-packed grafts that are covered with either a collagen or a nonresorbable membrane to the conventional alveolar ridge preservation procedures involving full-packed grafts and collagen membrane. The primary purpose was to evaluate the bone dimensional changes between the groups, and the secondary objective was to assess the potential contributing factors to clinical, radiographic and implant-related outcomes under different alveolar ridge preservation procedures.
two groups of inserted implants: trans-gingival and under-bone level; difference in the marginal bone loss at six months from placement between the two groups of implant positioned in the posterior atrophic maxilla
The aim of the project is to study the influence of biostimulate crops on a healthy population in order to assess influence on hematological parameters and specific metabolism (glucose, lipid, iron, bone) and gut and lipid hormones. Secondary outcome will be to find out micronutrient presence in urine and serum. The use of biostimulation in modern agriculture has rapidly expanded in recent years, owing to their beneficial effects on crop yield and product quality, which have come under the scope of intensive research.
The goal of this clinical trial is to test two different implant neck designs in 36 patients. The main question[s] it aims to answer are: - do triangular neck designed implants placed immediately after dental extraction have the same influence on peri-implant hard and soft tissues than regular neck designed implants at one year? - do triangular neck designed implants placed immediately after dental extraction have the same influence on peri-implant hard and soft tissues than regular neck designed implants at three years? Participants that present an unrepairable tooth on the anterior upper maxilla will be asked to take a CBCT scan in order to verify the presence of the buccal bone. Once this is verified the patients will enter in the study and the day of the surgery they will be assigned to either control or test group. - Control group: C1 round-neck implant - Test groups: V3 triangular-implant neck Researchers will compare test and control groups to see if they have the same effects on hard and soft tissues at 4 months, 1 year and 3 years.
The aim of this clinical trial is to compare serum concentration of bone intake proteins [ sex hormone-binding globulin (SHBG), cross linked C-telopeptide of type I collagen (CTX-I)] and muscle atrophy marker [creatine kinase (CK-MB)] between patients after the fracture of proximal femur and their age corresponding counterpart without the fracture. The main question it aims to answer is: • Is the higher concentration of bone intake proteins and muscle atrophy marker a predictive factor of proximal femur fracture? The part of participants (Group 1) will be hospitalized at the Department of Orthopaedics and Rehabilitation and will undergo a surgical treatment (open reduction of the fracture). The rest (Group 2) will be admitted to the Department of Internal Medicine. Participants of both Groups will have the blood sample test taken, to evaluate and compare the serum concentration of SHBG, CTX-I and CK-MB proteins.
