Hepatitis B at the Dakar Dental School

: Numerous studies have revealed the personal risk of contamination of the virus hepatitis B (HBV). Dental surgeons are chiefly concerned about their almost continual contact, professionally, with blood and saliva. The authors report the results of a study done at the Dental Institute of Dakar. This study revealed the importance of AgHBS and its different functions during the period of observation. A particular point of this study is to emphasis subjects of serology, notably AgHBS+ Anti HBC-, which produce an alternative virus. This study, which is being followed up, has already enabled the commencement of disease prevention programmes of hepatitis through the vaccination of some students: protecting both the dental surgeons and their patients.
