Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Therefore, clinicians are always looking for additional therapies to minimize complications, helping patients have a more comfortable experience after wisdom tooth surgery.
To date, placing grafting materials such as bone or other biological materials (growth factors, platelet-rich plasma, platelet-rich fibrin) into the tooth socket has been shown to be able to preserve the alveolar crest after extraction. However, these materials require preparation time, are costly, and have the risk of infection related to bone grafts.
Meanwhile, low-level laser therapy (LLLT) is known as a safe, non-invasive therapy that can affect cell metabolism without causing tissue damage. This therapy has been widely applied in many fields of medicine in general and in dentistry in particular. Low-level lasers have been studied to help reduce swelling, pain, and jaw tightness after impacted lower wisdom teeth surgery. In vitro or in vivo studies evaluating the healing effect of low-level lasers have given very positive results. However, there is still a lack of scientific evidence to prove the healing effect of low-level lasers on human tooth extraction sockets.
The study we conducted is a scientific study, in the field of Dentistry. This study aimed to evaluate the effectiveness of low-level laser on soft tissue and bone healing after surgical extraction of impacted lower third molars in a group of Vietnamese population.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control arm
After had third molar extraction at one side, patients do not receive low level laser therapy at this site (by not activating the tip)
No interventions assigned to this group
Experiment arm
After had third molar extraction at the other side, patients receive 7 sessions of low level laser therapy at this side (the day of surgery, then first day, third day, seventh day, fourteenth day, twenty first day, twenty eighth day after surgery)
Low Level Laser Therapy
Patients will receive LLLT at one side after third molar extraction surgery. There will be 7 sessions at the day of surgery, then first, third, seventh, fourteenth, twenty first, twenty eighth day after surgery.
