About this study

Orthodontics movements can cause inflamatory changes in the pulp and external inflamatory root resorption, different methods have been suggested to control that changes as the use of the low power laser. The objective of this study is to evaluate the low power laser effect on the inflamatory pulpar change and inflamatory external root resorption in maxillary premolars with intrusive orthodontic movements of 4 ounces during 12 weeks. Total sample were 34 healthy teeth, 16 were used to evaluate the normal standar and 18 were divided in two groups, the experimental group with the low power laser effect had a dose of 18 joules after activations of the orthodontic intrusion and the control group had a simulated effect in the same orthodontic movement. Teeth were extacted after 12 weeks and histological changes were evaluated in the dentinal-pulp complex and the pesence of external inflamatory root resorption. Findins suggest that low power. Laser decreased the inflamatory changes of the dentinal - pulp complex and the severity of the external inflamatory root resorption.

Treatment and study plan

Low power laser in teeth after intrusive movement

Radiation

Low power laser was aplied to premolar teeth under an intrusive movement to study histological changes and root resorption

Simulated laser in teeth with intrusive movements

Other

Simulated laser in teeth with intrusive movements for histological and root resorption changes

Primary outcomes

    Time frame: 12 weeks

    Histological changes and root resorption were assesed in Teeth with intrusive movement after a low power laser application

Secondary outcomes
