Treatment Result of Zirconia Laminate Veneer

This study aims to evaluate the clinical performance of the zirconia laminate veneer, a minimally invasive prosthetic restoration

The Impact of Adhesion Strategy on the Clinical Performance Of Indirect Dental Restorations

The goal of this clinical trial is to evaluate whether different cement systems influence the clinical outcome of posterior tooth supported zirconia crowns in adult patients requiring single crown restorations. The main questions it aims to answer are: * Do glass ionomer cements provide clinical outcomes comparable to those of resin cements for posterior zirconia crowns? * Do marginal discoloration, marginal integrity, and biological complications differ between the cement systems? * Do patient reported and clinician reported outcomes differ between the cementation procedures? Researchers will compare zirconia crowns cemented with either a glass ionomer cement or a resin cement to evaluate differences in clinical outcomes. Participants will: * Receive posterior zirconia crowns fabricated according to standardized clinical procedures * Be randomized to cementation with either a glass ionomer cement or a resin cement * Undergo clinical examinations assessing crown survival, marginal adaptation, discoloration, caries, periodontal status, and wear * Complete questionnaires regarding patient comfort and treatment experience * Attend baseline and annual follow-up examinations for up to 10 years

Platelet-Rich Fibrin (PRF) vs Bone Graft With Membrane for Ridge Preservation After Tooth Extraction

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).

Composite Repair Using Silane Coupling Agent

Evaluation the influence of the use of silane coupling agent application as a separate step versus application of silane or acid resistance silane containing adhesives on the clinical performance of repaired posterior resin composite restorations according to Modified United States Public Health Service (USPHS) criteria over one year.

Surgical Extrusion: Volumetric and Insertion Analysis at 6 Months.

The aim is to clinically evaluate the changes that occur in teeth that have undergone surgical extrusion treatment. Three parameters will be recorded before and 6 months after treatment: the position and the volume of the soft tissue, and the level of periodontal attachment.
