BACKGROUND: The aim of this clinical trial was to compare the effects of three oral sprays containing chlorhexidine (CHX), benzydamine hydrochloride (B-HCl), and CHX plus B-HCl (CHX/B-HCl) on plaque and gingivitis. METHODS: Fifty-one periodontally healthy volunteers, randomly divided into three spray groups, refrained from all mechanical oral hygiene measures for 7 days and, instead, used one of the randomly assigned sprays twice daily. The plaque index (PI), gingival index (GI), and gingival bleeding time index (GBTI) were assessed at days 0 and 7. Side effects were also evaluated. RESULTS: In all groups, PI, GI, and GBTI showed significant increases from the baseline to day 7. There were no significant side effects for B-HCl spray and CHX spray at day 7, but, for CHX/B-HCl, burning sensation significantly increased from the baseline. For all parameters, there were significant differences between B-HCl and CHX/B-HCl and between B-HCl and CHX, but no significant differences were observed between CHX/B-HCl and CHX. In addition, a significant difference was found between CHX/B-HCl and CHX with regard to burning sensation. CONCLUSIONS: These results indicate that both CHX and CHX/B-HCl sprays have equal clinical effectiveness, but only B-HCl spray has less anti-plaque and anti-gingivitis effects. Furthermore, CHX/B-HCl spray causes more side effects.
