Dentin sensitivity

This study tests a new type of dental filling made with graphene, a super-strong material, for teenagers aged 10-16 who have weak enamel (a condition called MIH). The fillings are custom-made using a digital scanner and are meant to be more durable and less sensitive than standar…

This trial tests whether a toothpaste with calcium sodium phosphosilicate reduces tooth sensitivity better than a regular fluoride toothpaste. About 192 adults with sensitive teeth will brush twice daily for 8 weeks. Researchers measure how teeth respond to a puff of air and a ge…

This study tests two simple treatments for tooth sensitivity caused by worn enamel: a blue diode laser and a bioactive glass powder. Thirty adults with two similarly sensitive teeth will each receive both treatments (one per tooth) to see which works better. The goal is to find a…

This study tests whether three different desensitizing toothpastes can reduce tooth sensitivity in people with braces. About 200 adults aged 18-40 with mild to moderate sensitivity will use one of the toothpastes or a placebo for 8 weeks. The goal is to see if the special toothpa…

This study tests whether a gel made from the Libidibia ferrea plant can reduce tooth sensitivity after professional whitening. Seventy-five adults will receive either the experimental gel, a standard desensitizing gel, or a placebo before bleaching with hydrogen peroxide. Partici…

This study tests whether a gel made from propolis (a bee product) can reduce tooth sensitivity after professional whitening. 66 adults will receive either propolis gel, a standard desensitizer, or a placebo before bleaching. Their pain and color change will be tracked for two wee…

This study tests whether applying a dipotassium oxalate gel before placing a filling can reduce tooth sensitivity afterward. 64 adults with sensitive tooth cavities will be randomly assigned to get the gel or standard treatment. Pain is measured at 24 hours, 7 days, and 30 days u…

This study compares two treatments for dentin hypersensitivity (tooth sensitivity). One group gets a special varnish (CPP-ACPF) alone, the other gets the varnish plus a low-level laser treatment. 70 adults with sensitive teeth will rate their pain before and after. The goal is to…

This study tests whether applying Gluma desensitizer before a filling can reduce tooth sensitivity afterward. Sixty adults with cavities in their back teeth will be randomly assigned to get either the desensitizer plus a standard filling or just the standard filling. Their pain r…
