Filter by:PICOT elements:P: Teeth restored with indirect tooth colored restoration I: Immediate dentin sealing using universal adhesive C: Delayed dentin sealing O: Post-operative Hypersensitivity T: -Hypersensitivity assessment one week during provisionalization period and post-cementation S: Randomized Controlled Clinical Trial
The purpose of this study is to establish the rationale for the practice of performing an oral reintroduction test without previous skin tests in children at low risk of IgE-mediated reaction or drug-induced toxidermia, and to confirm the criteria for a drug reintroduction test could be performed without previous skin tests, without subsequent risk of reaction for the child. The primary endpoint will be the risk of a severe IgE-mediated or delayed hypersensitivity reaction in children who received beta-lactam drug reintroduction protocol prior to skin testing.
revising penicillin allergy in the medical records, by taking full medical history and giving a challange test, in order to imrove the medical records and treatment possibilities.

The study aim to evaluate the difference between the effect of zinc modified glass ionomer and conventional glass ionomer on the success of partial caries removel technique
The investigators designed a randomized controlled trial to evaluate whether perioperative Vaginal preparation is superior to no Vaginal preparation in decreasing post CS endometritis. Since CS is performed in about 30% of all births and infection complicates 6-11% of all CS reducing the rate of this post CS complication can have a major impact not only on the hospital occupancy and costs but also on the new mother experience and ability to face the challenge that awaits for her with her newborn. In this study patients will be randomly assigned into two groups. The experiment group will not undergo any vaginal preparation. The control will undergo perioperative vaginal preparation with antiseptic soap followed by chlorohexidine-alcohol Both groups will be checked for cervical dilation with sterile gloves before surgery. Primary outcome - signs of endometritis (e.g. erythema around surgical scar, discharge or pain). Patients will be followed daily until discharge. A blood count will be drewn before discharge to rule out signs of infection. Patients will be contacted 6 weeks after surgery by telephone to inquire about any signs of infection, Emergency Room visits or ambulatory visits to the doctor due to endometritis. The participants will be asked if they had positive skin culture or other wound complications such as cellulitis, seroma or scar separation. The investigators estimated that 1040 patients will have to enroll into the study, 520 in each group in order to have 80% power to detect 50% difference in the endometritis rates between the two groups with a two tailed α level of 0.05. The data analysis was conducted according to the per-protocol principle.
This is a randomized, triple-blind, placebo-controlled study. 51 subjects with a confirmed diagnosis of dentin hypersensitivity were randomized to one of three treatments: Arginine based toothpaste, strontium acetate based toothpaste , or placebo. Treatment will be done at baseline then patients will use the toothpaste at home twice per day by using soft bristled tooth brush and the given dentifrice using modified stillmans method as explained by examiner. Standard test stimuli is calibrated short blast of air syringe, will be applied to sensitive dentin surfaces. Subjects recorded the intensity of sensitivity in response to stimulus on a visual analog scale at baseline, and after 1 week, 2 weeks and 3 months.

The aim of this clinical trial is to evaluate the tolerance and efficacy of a dental gel in patients with dentinal hypersensitivity.
