We have now carried out over 800 Previser Exams to date. All our patients so far have been pretty enthusiastic about them and the detail it gives them about the condition of their mouth and any future risks they may face. There have been approximately 28000 Previsers carried out to date by Denplans 3000 Denplan Excel accredited Dentists. At this rate, we should have carried out one for every denplan patient registered with the practice by Christmas. They will then be carried out at approximately yearly intervals.
