Objective: To investigate the relationship between a micropulse vibration device and pain perception during orthodontic treatment.
Materials and methods: This study was a parallel group, randomized clinical trial. A total of 58 patients meeting eligibility criteria were assigned using block allocation to one of two groups: an experimental group using the vibration device or a control group (n = 29 for each group). Patients used the device for 20 minutes daily. Patients rated pain intensity on a visual analog scale at appropriate intervals during the weeks after the separator or archwire appointment. Data were analyzed using repeated measures analysis of variance at α = .05.
Results: During the 4-month test period, significant differences between the micropulse vibration device group and the control group for overall pain (P = .002) and biting pain (P = .003) were identified. The authors observed that perceived pain was highest at the beginning of the month, following archwire adjustment.
Conclusion: The micropulse vibration device significantly lowered the pain scores for overall pain and biting pain during the 4-month study period. (18)
PBM Implant uses 680 nm near-infrared (NIR) light, which is similar to heat lamps, to deliver energy gently but directly to the bone and tissue around the implant body. Similar to plants and photosynthesis, the tissue can absorb this light energy and convert it to chemical energy, which stimulates the cells for faster bone and soft tissue regeneration and faster implant stability.
