1 year Oral Health Science BSC at Essex valid for post graduate BDS?

Oral Health Science BSc on the Essex uni website says it’s one year but I thought a bsc was 3 years?? Kind of confused but if anyone could let me know if it’s valid pls do say thank youu

As I understand... The FdSc is 2 yrs to qualify as a DH, the 3rd year is the BSc which is optional to qualify as a DT and you can do this anytime after the FdSc, but you can only enroll on it if you have done the FdSc. Hope that makes sense...
