Filter by:Background: Pyrimidine and purine metabolism disorders (DPPMs) affect how the body metabolizes chemicals called pyrimidines and purines. DPPMs can cause dysfunctions throughout the body, especially in the brain, blood, kidneys, and immune system. People with DPPMs might have no symptoms, mild symptoms, or they may have severe, chronic symptoms, that can be fatal. DPPMs are not well understood, and researchers want to learn more about what causes them and how to treat them. Objective: To learn more about factors that affect DPPMs by comparing test results from affected, uaffected family members, and healthy people. Eligibility: Three types of participants are needed: people aged 1 month and older with DPPMs; their family members who do not have DPPMs; and healthy volunteers. Design: Participants with DPPMs will come to the clinic once a year; some may be asked to come more often. At each visit, all affected participants will have a physical exam and give samples of blood, urine, saliva, and stool. Depending on their symptoms, they may also have other procedures, such as: Swabs of their skin and inside the mouth. Tests of their heart, kidney, brain, and nerve function. Questionnaires about what they eat. Dental exams, and exams of their hearing and vision. Tests of their learning ability. Monitoring of their physical activity. Imaging scans. Photographs of their face and body. These tests may be spread over up to 7 days. Affected participants may remain in the study indefinitely if they wish to. Healthy volunteers and family members will have 1 study visit. They will have a physical exam and may be asked to give blood, urine, saliva, and stool samples.
In this study, the postoperative clinical and microbiologic effects of chlorhexidine toothpaste and chlorhexidine-free toothpaste with the same content were compared after bilateral mandibular impacted third molar surgery. Similarly positioned fully impacted impacted lower third molars were extracted. Bilateral impacted wisdom teeth of the patients were randomly selected. After the operation, the experimental group received Dentasave 0.2% chlorhexidine toothpaste containing chlorhexidine and the control group received toothpaste with the same content but without chlorhexidine. Teeth were extracted by the same dentist at 14-day intervals. For microbiological analysis, saliva samples were taken before the first tooth extraction, before the second tooth extraction 14 days later and on the 28th day and sent to the microbiology laboratory. Wound healing, edema and trismus in both extractions were evaluated 1 week after tooth extraction. Wound healing was evaluated as good, acceptable and poor. VAS (Visual Analog Scale) was used for pain assessment and recorded 14 days after tooth extraction.
A Phase 1, Open-Label, Prospective, Dose-finding Clinical Trial for Evaluation of Safety and Tolerability of Intramuscular Injections of CLZ-2002 for the Treatment of Subjects with Charcot-Marie-Tooth type 1(CMT 1)
The goal of this clinical trial is to test the effects of prophylactic antibiotics in healthy individuals who are in need of surgical crown lengthening. The main question it aims to answer is if single dose antibiotics prior to surgical crown lengthening has any effects on the healing outcomes. Participants will be asked to take either - 2 g of amoxicillin + clavulanate, or - placebo, one hour prior to surgery and without knowing what medicine they took. Researchers will compare the wound healing and self-reported outcomes of the antibiotics group and placebo group.
The goal of this Natural History Study for Charcot-Marie-Tooth is to acquire, record, and analyze patient-reported data and associated genetic reports, Electronic Health Records (EHRs) and clinical notes to identify the burden, diagnostic journey, and prevalence of disease that will aid scientists in their work toward finding a cure. Participants will be asked to complete a Natural History Survey.
The long term goal of this proposal is to precisely characterize the auditory and vestibular abilities of children with Charcot-Marie-Tooth (CMT) and how these abilities evolve during the progression of the disorder. This information will be used to refine the management methods for hearing loss and vestibular disorders in these patients. Given that the phenotypic severity is variable within the CMT patient population, we predict that not all CMT patients will present with auditory and vestibular dysfunction. We will therefore collect specimens (i.e., buccal swabs and saliva) from study participants so that their DNA can be isolated and used to determine the genetic basis for auditory and vestibular dysfunction in peripheral neuropathies.
The study aims to evaluate the knowledge, attitude, and practice of dental practitioners from Cairo and Riyadh regarding caries preventive measures.
The aim of the study is to evaluate the knowledge, attitude, and practice of a group of dental practitioners from Cairo and Riyadh regarding caries risk assessment and management.
Charcot-Marie-Tooth disease (CMT) is a group of the most common hereditary peripheral neuropathy with high clinical and genetic heterogeneity. Biallelic pathogenic variants in SORD gene leading to loss of function of SORD protein cause axonal degeneration. Current research suggests that SORD-CMT2 may be the most common subtype of AR-CMT2. The primary purpose of this study is to explore the natural history of SORD-CMT2 patients by detecting the ONLS scale score and serum sorbitol level changes at 6th, 12th, 24th, and 36th months and to evaluate the effectiveness and safety of epalrestat. Patients with strong treatment willingness and voluntary purchase of drugs are included in the epalrestat treatment group, and patients without drug treatment willingness are included in the control group. Patients in the drug treatment group take epalrestat (50 mg) orally three times daily. This study is expected to be carried out simultaneously in 5 hospitals in mainland China. About 30 SORD-CMT2 patients will be enrolled in this study, and the study period will be 36 months.
Root canal therapy plays an importanmt role in dental health care.An importanat parameter necessary to achieve a proper endodontic treatment is quality of root canal filling.This study compare the radiographic quality of obturation with cold lateral condensation and thermoplasticiszed gutta percha technique and obtura II system.
