The Piraeus Dental Association (OSP) is a professional organization supporting dentists and advancing dental science in the Piraeus area. Active since 1926, it promotes oral health, continuing education, professional solidarity, and the development of dentistry. Its website serves as an information and service hub for members and the public.

The association provides a directory of dentists with active licences, information on membership registration and permits, access to e-prescribing and member payments, and updates on legislation and professional obligations. Members can find announcements, offers, and listings for job opportunities, dental equipment, and professional premises. The site also shares news for dentists and the public, alongside updates from the Greek Dental Federation and the FDI.

OSP organizes and publicizes scientific webinars, conferences, one-day events, and practical seminars covering dental developments, techniques, and care. It also supports public engagement in oral health, including educational initiatives for students. Based in Piraeus, the association offers professional resources, event information, and guidance through its website and office.
