简要总结
There is scarcity in the literature regrading the effect of Low Level Laser Therapy (LLLT) on the rate of en-masse retraction. This study aims to investigate whether LLLT would affect the rate of en-masse retraction in females having bimaxillary dento-alveolar protrusion.
详细描述
Individuals having bimaxillary dentoalveolar protrusion are characterized by proclined upper and lower incisors and increased procumbency of the lips thus suffering from poor facial esthetics. The conventional management of these patients is the extraction of the first premolars and retraction of the anterior teeth.
One of the treatment techniques is in the form of canine retraction followed by four incisors retraction. This conventional method takes tedious work and tremendous time, thus affecting the patients' satisfaction adversely. The other technique is retraction of the whole set of anterior teeth as one unit (Canine and incisors), which is referred to as "En-Masse retraction".
Enhancing the rate of orthodontic tooth movement has always been a supreme goal of orthodontic research hoping to raise the level of care delivered to patients, hence, increase patients' satisfaction.
One of the proposed modalities of increasing the rate of tooth movement is Low Level Laser Therapy (LLLT). Thus, the aim of the current consideration was to evaluate the impact of LLLT on the rate of en-masse retraction in adult females having bimaxillary dentoalveolar protrusion.

盲法说明
Due to the nature of the intervention neither the operator nor the patients could be blinded. The assessors will be blinded from the data to be investigated he will just measure the data needed without knowing the purpose of the study, and without knowing which records belong to which group. Two assessors will carry out the the analysis of the study, blindly and independently.
