Prospective clinical study evaluating the long-time adjunctive use of chlorhexidine after one-stage full-mouth SRP.

摘要

Concerning this paper (1), I would like to remind you that most of the full-mouth SRP-studies published during the last 10 years are not following the protocol described by Quirynen et at. (2). Also, in the presented paper by Stratul et a/, on page 2, it is pointed out that they performed intrasulcular irrigation with 0.2% CHX. In the paper from Quirynen and in other papers in the original full-mouth disinfection by Osterwaal era/. (3), at least 1% solution or gel was used and this solution was used three times to achieve the contact time of 5 min. If lower concentration like in the present study of 0.2% CHX is used, there is no effect on the paropathogenic bacteria.
