Abstract
INTRODUCTION:\ud The study aimed at evaluating the effect of chlorhexidine (CHX) in preventing plaque biofilm (PB) formation on healing abutments (HAs) in patients rehabilitated with osseointegrated implants.\ud MATERIALS AND METHODS:\ud Fifty HAs were placed in 34 voluntary patients 1 week after implant surgery (test group). After 7 days, a new set of 50 HAs was placed in the same implant sites and removed 1 week after (control group). During the 2 testing periods, patients were instructed to apply: CHX mouth rinsing twice daily and no brushing (test); no CHX mouth rinsing and no brushing (control). Scanning electron microscopy and image analysis were blindly used to objectively quantify PB amount on removed HAs.\ud RESULTS:\ud Median values and interquartile ranges of the percent ratio of titanium surface covered from PB were 0.9 (0.1-4.1) and 1.2 (0.1-11.6) for test and control groups, respectively (P = 0.0275).\ud CONCLUSIONS:\ud CHX mouth rinsing significantly limited plaque formation on HAs, being a valid contribution to mechanical brushing in early phases of plaque control on dental implantsKeywords
