Suggest Remedy For Lung Scar With History Of Pulmonary Tuberculosis

I had a minimal ptb before about 8 years ago and underwent medication for 6 months. Everytime I had my xray for my pre-employment the result would always be fibrotic kochs residuals in the right upper lobe and so I had to go through sputum test to ensure that I am negative for PTB. My question is that, when will the scar be removed or perhaps unreadable during chest xray? Appreciate your reply and advise. Thanks
