The Effect of the Cold Arm Sling Elevation Pillow on Postoperative Anxiety and Comfort in Children

The purpose of this clinical trial is to learn whether the use of a "cold and arm sling elevation pillow" affects anxiety and comfort levels in children aged 7-12 years undergoing surgery for upper extremity fractures. The main questions it aims to answer are: * Does the use of a cold and arm sling elevation pillow reduce postoperative anxiety levels in children? * Does the use of a cold and arm sling elevation pillow increase postoperative comfort levels in children? Researchers will compare the experimental group (using the specially designed cold and arm sling elevation pillow) with the control group (receiving standard clinical care, including standard pillows and separate ice packs) to see the effects of the integrated pillow on anxiety and comfort. Participants will: * Receive education before surgery based on their randomly assigned group (experimental or control), * Use the assigned elevation and cold application method for the first 24 hours following surgery, * Complete anxiety and comfort assessment scales at four different time points: before the intervention, just before surgery, 6 hours after surgery, and at the time of discharge.

Comparison of Patient-Reported Comfort Between Two Clear Aligner Trimming-Line Designs: A Split-Mouth Study

* The trimming-line design of clear aligners (supragingival versus juxtagingival) is a routine clinical decision whose influence on patient-reported comfort has not been established; available evidence on aligner comfort derives almost exclusively from comparisons with fixed appliances. * This observational, cross-sectional study compares two clear aligner trimming-line designs with respect to patient-reported comfort: a supragingival design, whose edge rests on the marginal gingiva, and a juxtagingival design, whose edge follows the gingival contour without covering it. Because the two designs sit differently against the gingival soft tissue, they may be experienced differently during wear. * Participants are patients already wearing one trimming-line design on one dental arch and the other on the contralateral arch; each participant thus serves as their own control. After a minimum of four weeks of wear, participants complete a 20-item questionnaire once, rating the frequency of defined oral experiences for the maxillary and mandibular arch separately on a three-point ordinal scale (0 = none, 1 = occasional, 2 = frequent). * The questionnaire is anonymous; the design worn on each arch is identified from which of two identical forms a participant completes. Responses for the two designs are compared within each participant. The study evaluates whether trimming-line design is associated with differences in patient-reported comfort.

Effect of Cyanoacrylate and Concentrated Growth Factor on Palatal Donor Site

The aim of this planned randomized controlled clinical study is to evaluate the morbidity of the palatal donor area after free gingival graft (FGG) operations. In this study, wound healing and pain levels in the palatal region will be evaluated after cyanoacrylate and concentrated growth factor (CGF) applications.

Patient-Reported Outcomes of Four Intraoral Suture Materials

When patients undergo minor oral surgery, dentists use various types of stitches (sutures) to help the gums heal. These stitches can be made of different materials, and some might feel more comfortable, cause less pain, or interfere less with eating and speaking than others. The purpose of this study is to compare four commonly used dental suture materials to see which ones patients prefer. Participants in this study will receive four different types of stitches in different areas of their upper jaw after a routine dental procedure. Patients will be asked to report their levels of pain, discomfort, and any difficulties with daily activities like eating and talking on Days 3, 7, and 14 after the procedure. A panel of dental specialists will also examine photos of the healing process to see if one material helps the mouth heal better than others. This research will help dentists choose the best materials to improve patient comfort after oral surgery.
