Objective: To compare disinfecting effectiveness of 2% glutaraldehyde and 4.8% chloroxylenol on tooth extraction instruments at the Department of Oral Surgery, Faculty of Dentistry, University of North Sumatera. Material and Methods: This was an experimental study with posttest only control group design approach. Purposive technique is applied to collect samples which are lower molar extraction forceps. In this study, sample were divided into 2 groups and each consisting of 18 instruments. The treatment group was treated with 2% glutaraldehyde while the control group was treated with 4.8% chloroxylenol. Each instrument was pre-cleaned using a brush, water and soap for both groups underwent the disinfection process. Results: The results were statistically analyzed using Mann-Whitney Test. The comparison between glutaraldehyde and chloroxylenol showed a significant difference to the total bacteria count on instrument after disinfection (p=0.014 < 0.05). Conclusion: 2% glutaraldehyde was more effective than 4.8% chloroxylenol at disinfecting lower molar extraction forceps.
