12. Ultrasonic curettage- using ultrasonic devices ultrasonic vibrations disrupt ts continuity & lift off the epithelium results in a narrow band of necrotic ts  ed infl n & less removal of C.T These inst’s are not as effective as hand inst’s in removing c.t. & leaving a smooth pocket wall Chemical curettage- using caustic drugs sodium sulfide alk sodium hypochlorite phenol These were discarded after studies showed their ineffectiveness The extent of ts destruction cannot be controlled They may  rather than reduce the amount of ts to be removed by enzymes & phagocytes

13. HEALING:  immediately after curettage, a bld clot fills the pocket area ( this is organized into granul n ts) haemorrhage in ts (dilated cap’s) &  PMNL’s on wound surface  rapid proliferation of granul n ts  ts maturation (  smal bld vs)  epithelization of sulcus takes 2-7 days CLINICAL APPEARANCE: immediately after curettage, gingiva appears hemorrhagic & bright red after 1 wk, gingiva is slightly redder than normal apical shift in position of marginal gingiva after 2wk, normal color, contour, consistency, s.t. gingival margin well adapted
