Oral and written information should be supplied in simple, straightforward language. Patient should be informed about the procedure and what is coming next. A chart like the one below can be prepared and given to patient.

more rapid healing and adequate positioning of the flap.

An angled micro handpiece and micro round bur or ultrasonic tip can be used for retropre‐ paration. The bur or tip is placed at the apical opening of the canal and guided gently deeper into the canal as it cuts. Once the retropreparation is completed the prepared cavity is inspect‐ ed. The gutta-percha at the base is recondensedwith small 0.5 mm microplugger (Fig:6). After that orot end filling material can be applied. The aim of placing root end filling material is to establish an apical seal that inhibits the leakage of residual irritants from the root canal into

After finishing surgical procedures the flap is returned to its original position and is held with moderate digital pressure and moistened gauze. Primary closure of the elevated flap is gained by basic or interrupted sutures. Absorbable monoflament or sling suture material is commonly used. After suturing, the flap should again be compressed digitally with moistened gauze for several minutes to express more hemorrhage. This limits postoperative swelling and promotes
