-
Autologous Tooth Graft vs. Bovine Xenograft for Healing After Lower Wisdom Tooth Extraction
This study tests whether using tooth-derived grafts from the extracted tooth or bovine grafts improves healing of periodontal defects after removing impacted lower wisdom teeth, compared to natural blood clot healing.
-
Checking how well laser speckle contrast imaging measures gum blood flow
We will test whether laser speckle contrast imaging (LSCI) can reliably measure superficial gum blood flow in healthy adults and in people healing after periodontal or implant-related soft-tissue surgery.
-
AI-assisted therapeutic exercise for knee osteoarthritis
A brain-smart exercise app is being tested to see if it helps knee pain and function more than a paper home exercise plan for adults with knee osteoarthritis.
-
Theravex Oral and Theravex Tissue Care Plus to improve healing after mucogingival surgery
We will test if applying Theravex Tissue Care Plus during a modified free gingival graft and rinsing with Theravex Oral afterward helps adults with lower-front gum recession heal faster and get better root coverage than a saline placebo.
-
Single-session electrical nerve stimulation for sciatic-related leg pain
A one-time Percutaneous Electrical Nerve Stimulation (PENS) treatment near the sciatic nerve is tested to see if it helps long-standing leg pain from low back issues.
-
Controlled breathing added to exercise for people with multiple myeloma
This study tests whether adding a home-based controlled breathing program to a therapeutic exercise plan helps improve heart and lung health in adults with multiple myeloma.
-
PENS near the sciatic nerve plus therapeutic exercise for leg pain from sciatica
This study tests whether a nearby nerve stimulation procedure combined with a structured exercise program can help people with long-lasting sciatica pain.
-
How accurate are metal sleeve–free fully guided dental implants?
This trial will test if metal sleeve–free 3D-printed surgical guides, using two different drill channel sizes in a split-mouth design, place implants accurately in adults needing complete-arch dental rehabilitation.
-
Comparing digital methods to improve fit of full-arch implant-supported prostheses
This will test three digital workflows to see which gives the best passive fit for adults receiving fixed full-arch implant-supported prostheses.
-
Accuracy of pre-made screw-retained temporary crowns placed with digital planning and guided implant surgery
This project will test whether a fully digital planning and guided surgery workflow lets pre-made screw-retained temporary crowns seat accurately for adults needing a single immediate dental implant.
-
Controlled breathing added to therapeutic exercise in multiple myeloma
This trial tests whether adding a home-based controlled breathing program to a therapeutic exercise plan helps reduce somatic symptoms in adults with multiple myeloma.
-
Mobile AI app to predict glucose and suggest insulin bolus doses for people on multiple daily injections
This study will test whether a smartphone AI app can help adults with insulin-requiring diabetes on multiple daily injections predict blood sugar and suggest bolus doses to increase time-in-range and reduce highs and lows.
-
Comparing high versus low electrical frequencies delivered through fine needles to improve shoulder muscle strength and pain sensitivity
This trial will test whether high- or low-frequency percutaneous electrical nerve stimulation using fine needles helps improve shoulder muscle strength and increases pressure-pain thresholds in people with shoulder pain and a latent trigger point in the infraspinatus.
-
Comparing two gum tunnel graft techniques (MCAT vs VISTA) to increase gum thickness
This trial will test whether the MCAT or VISTA tunnel surgery with connective tissue grafts better thickens gums and covers exposed roots in adults with multiple adjacent gingival recessions.
-
Salivary biomarker panel to predict periodontal health over 2 years
A 2-year observational study will test whether a panel of saliva biomarkers can predict periodontal health status in adults with varying periodontal conditions.
-
Pressure-guided limited bone removal versus standard laminectomy for symptomatic lumbar spinal stenosis
This test will see if using epidural pressure to guide a smaller bone removal works as well as standard open laminectomy for people with symptomatic lumbar spinal stenosis.
-
Comparing 3D-printed and milled surgical guides for dental implant placement
This study tests whether 3D-printed or milled surgical guides work better for placing dental implants accurately to improve patient outcomes.
-
Evaluating the effectiveness of surgical guides for zygomatic implants
This study is testing if using special guides for placing zygomatic implants is more accurate and causes less pain than the usual freehand method for patients aged 18-80.
-
Using UVC to enhance dental implant stability
This study tests if using UVC light on dental implants can help them bond better with the bone and allow for quicker use after surgery.
-
Optimizing surgical hand preparation with Sorbectol
This study is testing how different application times of a hand sanitizer called Sorbectol can improve hand cleanliness for surgery by comparing the amount of bacteria on hands before and after using it.
-
Probiotic formula to see if it helps mild cognitive impairment
A probiotic supplement is being tried to see if it can help cognitive function in people aged 60–85 with mild cognitive impairment.
-
Impact of flapless piezoincision on periodontal health during orthodontic treatment
This study is testing if a new technique for orthodontic treatment without cutting the gums can improve gum health better than two types of grafting in adults with dental issues.
-
Comparing biofilm on zirconia and titanium dental implants
This study is testing whether dental implants made of zirconia or titanium collect different amounts of biofilm and how that affects patient satisfaction over a year.
-
Using micro-osteoperforations to improve orthodontic treatment in patients with severe gum disease
This study is testing if a new technique called micro-osteoperforations can help people with severe gum disease move their teeth more effectively during orthodontic treatment.
-
Online intervention for postpartum depression
This study is testing an online program to help women with postpartum depression by comparing two different types of support: one focused on changing thoughts and behaviors and the other on boosting happiness and well-being.
-
Comparing two surgical techniques for treating gum recession
This study is testing two different surgical methods for treating gum recession to see which one works better for covering exposed tooth roots.
-
Incidence of gum inflammation around dental implants in patients with treated gum disease
This study looks at how often gum inflammation happens around dental implants in people who have had gum disease treatment to see what might increase the risk.
