Flashcards in ScRP, and studies Deck (8):


oral hygiene instruction vs scaling and root planing
-2 groups 1)root planing +OHI or 2)OHI
Results: mean PD were reduced by 1.34 mm in group 1 and 0.56 mm in group 2
-mean attachment gain in group 1 =0.52 mm and group 2=0.05 mm



"healing following surgical/non-surgical txt of pd disease"
-sites that received SRP with surgery lost attachment when initial PD was less than 4 mm
-if initial PD was 4-6 mm= no change in attachment
-if initial PD were greater than 6 mm, sites gained attachment



"critical probing depths in pd therapy"
-sites that had open SRP lost attachment when initial PD were less than 4.2 mm
-sites that received SRP lost attachment when initial PD were less than 2.9 mm
-attachment gains with surgery surpassed scaling alone at initial PD of 5.5 mm



"four modalities of txt over 5 years"
-compared pocket elim/red surger, modified flap surgery, subging curettage and SRP
-1-3 mm pockets: scaling or curettage significantly less attachment loss than surgery
-4-6 mm pockets: scaling or curettage significantly more attachment gain than surgery
-7-12 mm pockets: no significant difference between procedures



"scaling and RP efficacy with and without flaps surgery"
-1-3 mm pockets, 86% of all surfaces were calc free in both SRP (open and closed)
-4-6 mm pockets, 43% of surfaces were calc free in closed SRP, and 76% were calc free in open SRP
-greater than 6 mm, 32% in closed, 50% in open



"healing following SRP"
-histo analysis at 9 months after SRP and oral hygiene regimen
-long junctional epithelium with no new connective tissue attachment


Rosenberg and Ash

"root surface roughness: why is it important?"
-3 groups, curette, ultrasonics, control
-results: roughness: control>ultrasonics>curette
-no significant difference in mean plaque score or mean inflammatory index between the groups



"root surface roughness"
-curette vs finishing bur
-results: roughness: bur>curette
-subgingival colonization was greater in the bur treated group
