Comparative efficacy of hand disinfection potential of hand sanitizer and liquid soap alone or in combination: a randomized controlled trial

This study is a randomized, parallel group trial comparing the hand disinfection efficacy of Hand sanitizer and liquid soap among dental students. Volunteers will be instructed to contaminate their hands by touching typical everyday surfaces (i.e. Door handles, tables, stools, routine dental instruments and dental chair) with both hands prior to testing. A swab from each participants’ hand will be taken both before and after the intervention. Swab are cultured on agar plates to determine a maximum spectrum of microbes present.
