Extraction, Tooth

This study uses a natural material called Platelet-Rich Fibrin (PRF) to help improve healing after tooth removal. PRF is made from your own blood. A small amount of blood is taken from your arm and spun in a machine to make a thick, sticky layer full of platelets. These platelets help your body heal. PRF acts like a "natural bandage" and may help your gums and bone heal faster. Because it comes from your own body, it is safe and lowers the chance of infection or problems. The goal of this research is to see if adding PRF to a bone graft (used to fill the tooth socket after extraction) can help the area heal faster and grow more new bone. If you join this study, it will last about 4 months. You will have two teeth removed, and each socket will get a different treatment: 1. One socket (test side) will get PRF + bone graft (this combination is also called "sticky bone"). 2. The other socket (control side) will get a bone graft + a covering called a barrier membrane (made of collagen). We will compare how well the two sides heal by looking at: 1. How the gums close over the area 2. How much pain you feel 3. How much the bone changes 4. How much new bone grows You will come to the clinic for about 9 visits in total. These visits are part of your regular treatment, along with a few extra steps for the study. One possible risk is bruising or soreness from the blood draw. If we cannot collect enough blood (about 60-80 ml) because your veins are too small or hard to find, you will not continue in the study, and both sockets will be treated using the control method (bone graft + membrane).

The purpose of this study is to compare two different bone graft materials (freeze-dried bone allograft, FDBA and collagen-enriched bovine xenograft, CEBX) that are routinely used for preserving the remaining bone after extraction of an anterior tooth, and before placing a dental implant. Patients will be randomly assigned to either group (flip of a coin) One group will receive FDBA material and the other group will receive CEBX (cow) material. The study aims to examine the following main questions: * Potential differences in linear radiographic horizontal (HRD) and vertical (VRD) ridge dimensional changes between groups after 16 weeks of healing * Other clinical information of the treated areas and information regarding the esthetics of the dental implant that will subsequently be placed at the edentulous site as well as patient satisfaction with the treatment, will be evaluated. The study will include 7 study visits. Study procedures will take place during the same visits as the standard of care treatments (tooth extraction and bone graft, dental implant placement, crown installation and follow-ups). Clinical information from these standard of care visits will be used for the current research study, such as: * Demographic information * Clinical information from intraoral photographs * Radiographic information from cone beam computed tomography and periapical radiographs.

This clinical trial is being conducted in the Department of Pediatric Dentistry, Faculty of Dentistry, Cairo University. The purpose of the study is to compare the pain perception and comfort of children during tooth extraction when using a computer-controlled local anesthetic device (SleeperOne® 5) versus the conventional syringe infiltration technique. Children between 3 and 5 years of age who require extraction of a maxillary primary molar will be invited to participate. Before starting, a topical anesthetic gel (benzocaine) will be applied. Then, local anesthesia will be given using either the SleeperOne® device or the traditional syringe, depending on the group assigned. Pain during injection and extraction will be assessed using both child-friendly rating scales and independent evaluation by the dentist. Patient anxiety, heart rate, and blood pressure will also be recorded. This study aims to provide evidence on whether computer-controlled anesthesia can reduce children's pain and anxiety compared with the conventional method, leading to a more comfortable dental experience. The study is a randomized clinical trial and will be conducted in a single visit at the Pediatric Dentistry Outpatient Clinic, Faculty of Dentistry, Cairo University. The results may help improve pain management and patient comfort during dental treatment for children.

This study aims to compare the pain felt by children during tooth extraction using two different techniques for giving local anesthesia. One group of children will receive anesthesia using a modern electronic device called SleeperOne® 5, which controls the flow and pressure of the anesthesia to reduce pain. The other group will receive anesthesia using the traditional syringe method, which is more commonly used in dental clinics. The study will include children between the ages of 3 and 5 years old who need to have an upper baby molar tooth extracted. All children in the study will be healthy (classified as ASA I or II), and their parents must agree to participate. During the procedure, each child will first receive a topical anesthetic gel to numb the surface. Then, based on random selection, the child will receive local anesthesia using either the SleeperOne® 5 device or the traditional syringe. Pain levels during the injection and during the extraction will be measured using special scales suitable for children. Other factors like how long the anesthesia takes to work and how long it lasts will also be recorded. This research will help dentists understand whether the SleeperOne® 5 device offers a more comfortable experience for young children compared to the traditional method. The goal is to reduce fear and pain during dental treatments for kids.
