Description
Ekin Beşiroğlu-Turgut, Gökçe Aykol-Şahin, and Yiğit Cem Öğretmen test in 2026 whether finger length ratios predict how well adults clean their teeth. The ratio of index to ring finger length reflects hormone exposure before birth, which some link to behavior. Whether it touches oral hygiene was unknown.
The study enrolled 126 adults at a dental clinic in Istanbul, measured fingers, and scored plaque and gum state before and after one week of standard cleaning instruction. Teaching improved scores for everyone. Finger ratio, though, showed no reliable link to plaque or gum change. Left-handed people kept lower plaque scores at both checks, and some brushing habits varied by ratio without showing in the clinical scores.
