Background and study aims
Despite evidence that antibiotics abuse is related to unknown pathogen infection, antibiotics are badly overused in China, as common people can easily buy antibiotics in pharmacy stores, even without prescriptions from doctors. The necessity and feasibility of antibiotics treatment after tooth extraction surgery, among the most common surgical operations, remain unclear. In order to ensure that the efficacy of antibiotics treatment in preventing postoperative complications in patients after tooth extraction surgery. We prescribe antibiotics for patients after tooth extraction. Then we invite then to have an examination about the wound to assess the degree of pain, swelling, opening degree and alveolitis. This study aims to recruit 200 blood donors to compare different intervals between patients with tooth extraction. The goal is to find the optimum interval for which it is safe for patients with tooth extraction.
Who can participate?
Adults over the age of 17 who have pericoronitis in the distal aspect of a third molar and are willing to have the tooth extracted at Nanjing University of Science and Technology Hospital.
What does the study involve?
Participants are asked to join this study while they are at Hospital of Nanjing University of Science and Technology in China. Participants must be over the age of 17 and have infection in the last molars. Participants are randomly allocated to one of two groups. Those in the first group as asked to took amoxicillin 0.5g/ and metronidazole 0.2g one hour postoperatively (three times every day) after tooth extraction. Those in the second group are asked to took a placebo with the same shape and dose on the same times. The study lasts for 7 days. Participants are asked to go back to check the wound in tooth extraction.
What are the possible benefits and risks of participating?
There will be no immediate direct benefit to those taking part. By taking part in this study there are no risks of physical injury or harm.
Where is the study run from?
The INTERVAL study is being run by the Nanjing University of Science and Technology and takes place in Hospital of Nanjing University of Science and Technology.
When is the study starting and how long is it expected to run for?
June 2015 to December 2017

Scientific title | Efficacy of antibiotics treatment in preventing postoperative complications in patients after tooth extraction surgery: a prospective, randomized, double-blind controlled study |
Study objectives | Using antibiotics after tooth extraction surgery does not provide additional benefits to Chinese population. |
Ethics approval(s) | The Institutional Review Board of Nanjing University of Science and Technology, 22/06/2015. |
Health condition(s) or problem(s) studied | Pericoronitis |
Intervention | Patients in the treatment group took amoxicillin 0.5g/ and metronidazole 0.2g one hour postoperatively (three times every day) for three days after tooth extraction. Patients in the placebo group took a placebo with the same shape and dose on the same times. Pain, swelling, mouth opening degree, and Alveolitis events were assessed at 7th days after tooth extraction. Bilateral molars in each group was were randomly assigned to two groups using a randomization software (version 1.0; Random Allocation Software, Isfahan, Iran) |
Intervention type | Drug |
Pharmaceutical study type(s) | |
Phase | Not Applicable |
Drug / device / biological / vaccine name(s) | Amoxicillin and metronidazole |
Primary outcome measure | 1. Pain was measured using a visual analogue score (VAS) at 7th days after tooth extraction. 2. Swelling was measured as the difference between the distance (mm) between the lower earlobe and the mesomentum on the extraction side at 7th days after tooth extraction. 3. Mouth opening degree was measured as the distance between upper and lower incisors at 7th days after tooth extraction. |
Secondary outcome measures | Alveolitis event was diagnosed by a dry appearance of the exposed bone in the socket after trauma. |
