Design outcomes

Primary

MeasureTime frame
To compare vertical and lateral displacement of gingiva achieved by plain retraction cord with impregnated retraction cord and diode laserTimepoint: Immediately after gingival retraction during first visit (Day 0 ) and at second visit after 1 week following alternate retraction method that is impregnated cord in group A and diode laser in group B—

Secondary

MeasureTime frame
To assess & compare the degree of pain experienced during these methods of retractionTimepoint: Immediately after gingival retraction procedure at first visit ( day 0 ) & second visit (day 7 );To calculate & compare the amount of time required during the application of impregnated retraction cord & diode laserTimepoint: Time required measured from initiation of gingival retraction to completion of impression making at first visit (day0) & second visit (day7)during each intervention—
