Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The participants will be divided randomly into two groups All Patients will receive single session of 532 nm subthreshold micropulse laser ,the following parameters will be used in all cases as follows,spot size : 200-µm ,exposure duration:200-ms ,power : 500-mW
While duty cycle will differ between 2 groups as follows :- Group A : will be treated using 5 % duty cycle . Group B : will be treated using 15 % duty cycle . follow up visits as follows 1 week ,4 weeks 12 weeks after laser therapy .
