The British Dental Students' Association (BDSA), founded in 1942, is a student association run by dental students for dental students. The Association represents over 5,000 dental students in the UK. The BDSA and British Dental Association are two separate organisations that work closely together. It is understood that the original BDSA tie was designed by Professor N A (Tony) Naylor at Guy's Dental Hospital in 1957. A subsequent design of BDSA tie was introduced in the 1980s. The exmaple of the original BDSA tie in the Archive was presented in thanks to one of the co-organisers (Iain Corran) of the 1980 BDSA Summer conference
