This study looked at 100 children aged 6 to 9 with cavities to see if dental treatment improves their chewing. Kids chewed a special two-colored gum before and three months after treatment, and a computer analyzed how well they mixed the colors. The goal was to measure if fixing …

This study looked at 184 children aged 7-12 to see if dental problems like cavities or missing teeth affect how they feel about speaking. Researchers gave the kids a questionnaire about their speaking attitudes and checked their teeth. The goal was to understand if poor oral heal…

This study looked at 51 people to compare levels of three substances (IL-8, FGF-1, and VEGF) in teeth that are healthy, mildly inflamed, or severely inflamed. Samples were taken from the tooth pulp, gum fluid, and dentin fluid during routine root canal treatment. The goal was to …

This study tested three different tooth-colored filling materials for cavities on the sides of teeth (Class II cavities). 47 healthy adults received fillings and were checked after 6 months and 1 year. Dentists rated the fillings on appearance, fit, and any problems like staining…

This completed study compared how well people with complex regional pain syndrome (CRPS), people with other muscle or bone pain, and healthy individuals can imagine movements. Researchers used a questionnaire called the MIQ-RS to measure motor imagery skills. The goal was to see …

This completed study looked at 120 adults with decayed premolars or molars to compare how long onlays and single crowns last, and how well they work. Participants received either a crown or an onlay made from different ceramic materials. The goal was to see which restoration type…

This study looked at 40 people with tooth inflammation (reversible or irreversible pulpitis) to see if certain immune markers in the blood (IL-8 and IL-10) could predict how well a tooth-saving treatment (vital pulp therapy) works. Participants received the therapy, and researche…

This study tested whether a tele-dentistry program using AI-generated content could improve awareness of early childhood caries (cavities) among 57 Egyptian children aged 5-10 and their caregivers. Participants received educational materials and were assessed at the start, after …

This study tested whether a 30-minute interactive lesson could improve dental interns' understanding of Molar-Incisor Hypomineralization (MIH), a condition that causes weak spots on teeth. Two hundred dental interns from Future University in Egypt took a quiz before and after the…

This pilot study tested a school-based program to encourage kids to drink more water. The program included student ambassadors, a kick-off event, and a student-led marketing campaign. Researchers looked at whether the program was feasible and if it could improve hydration, reduce…

This study checked on dentures with SR Phonares II teeth that had been worn for over 10 years. Researchers examined 17 people's dentures to see how many were still in use and how well they held up in looks, function, and health. The goal was to learn about the long-term survival …

This study looked at 72 children aged 4-7 who had never been to the dentist and needed a filling. Kids were randomly assigned to have a parent present, absent, or watching behind glass during treatment. Researchers measured anxiety using questionnaires, heart rate, and oxygen lev…

This study surveyed 116 adults with chronic pain at a rehabilitation clinic to understand how their pain beliefs, spiritual well-being, and attitudes toward complementary and alternative medicine are related. Participants filled out several questionnaires about their pain, mood, …

This completed study examined 160 children aged 3-14 to see if a Mediterranean-style diet and physical activity habits are linked to better oral health, including less tooth decay and healthier gums. Researchers checked children's teeth and gums and compared them to their eating …

This study tested three mouth rinses—plain water, a fluoride rinse, and one with plant extracts—to see how well they protect teeth from cavities and erosion. Twelve healthy adults used each rinse for five days while wearing special trays with tooth and dentin samples. The goal wa…

This study checked how stable teeth are in people with cemento-osseous dysplasia (COD), a rare jaw condition that can affect tooth attachment. Researchers used two non-invasive tools—a device that measures tooth vibration and a bite force sensor—to compare affected teeth with hea…

This study looked at 45 people with braces to see if different toothpastes change tooth color or cause white spots. Participants used one of three toothpastes: Colgate Total, Curaprox, or ROCS. Researchers used 3D scans and special fluorescence photos to measure color changes ove…

This study looked at two ways to place dental implants in the lower jaw: a flapless technique (using a small punch) and a flap technique (cutting the gum). Twenty patients were followed for 6 months to measure bone loss and implant stability. The goal was to see which method caus…
