Difference influence of rubbing and soaking tooth extraction instruments in 70% alcohol on total oral bacterial colonisation on clinical students at the Department of Oral Surgery and Maxilofacial March-May 2018

Objective: To compare the effect of rubbing and soaking tooth extraction instrument in 70% alcohol on total oral bacterial colonisation at the Department of Oral Surgery, Faculty of Dentistry, Universitas Sumatera Utara. Material and Methods: This is an experimental research with a post-test only approach. The sampling technique used is Purposive Sampling. In this study, sample were divided into 2 groups consisting of 18 extraction instruments which are lower molar forceps rubbed with 70% alcohol and soaked in 70% alcohol. Each instrument were pre-cleaned using brush, water and soap prior disinfection process. Results: The results were statistically analyzed using Mann-Whitney Test.
