Enamel caries

This trial tests whether coating clear orthodontic aligners with nano chitosan—a natural antimicrobial—can reduce white spot lesions (early enamel damage) that sometimes develop during aligner therapy. About 53 people with mild to moderate misalignment will wear either coated or …

This study tests whether a graft made from a person's own extracted tooth, with or without low-level laser therapy, helps regrow jawbone after a tooth is pulled. About 21 healthy adults who need at least two back teeth removed and later replaced with implants will take part. The …

This study tests two different varnishes for treating white spot lesions, which are early signs of tooth decay common after braces. One varnish uses a self-assembling peptide to help rebuild enamel, while the other delivers calcium and phosphate. Thirty-eight people aged 15-25 wi…

This trial tests whether a bioactive resin containing S-PRG filler, used as attachment material for clear orthodontic aligners, can prevent white spot lesions (early decay) on tooth enamel. Fifty healthy young adults with mild to moderate crowding will be randomly assigned to rec…

This study tests whether a topical 10% povidone-iodine solution can prevent white spot lesions on the front teeth of teens undergoing fixed orthodontic treatment. Healthy participants aged 10 to 17 will receive either the iodine solution or a placebo applied to all tooth surfaces…

This study tests whether adding a special glass material to standard fluoride varnish can better prevent root cavities in adults over 60. Researchers will compare the two varnishes in 540 older adults over 36 months. The goal is to see which one reduces new cavities and helps sto…

This study tests whether using a fluoride-releasing composite resin for aligner attachments can prevent white spot lesions (early cavities) during clear aligner therapy. Twenty-four people aged 16-24 with mild crowding will have one side of their mouth get the fluoride resin and …

This study tests whether applying fluoride varnish to teeth can prevent white spot lesions in people undergoing clear aligner treatment. Twenty-five participants aged 16 to 24 with mild crowding will have one side of their mouth treated with fluoride varnish and the other side le…

This study tests whether a 10% carbamide peroxide gel, used at home, can make white spot lesions on teeth less noticeable. About 67 adults with white spots on their front teeth will use the gel and report their satisfaction. The researchers will also check for side effects like t…

White spot lesions are a common cosmetic problem during orthodontic treatment. This study tests whether placing the small composite attachments on the tongue side of clear aligners, instead of the front, reduces these spots. Fifty-two young adults with mild to moderate crowding a…
