ScRP, and studies

Question 1

Tagge

Answer 1

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

Question 2

Lindhe.,

Answer 2

“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

Question 3

Lindhe

Answer 3

“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

Question 4

Ramfjord

Answer 4

“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

Question 5

Caffesse

Answer 5

“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

Question 6

Caton

Answer 6

“healing following SRP”

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

Question 7

Rosenberg and Ash

Answer 7

“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

Question 8

Lenkes

Answer 8

“root surface roughness”

• curette vs finishing bur
• results: roughness: bur>curette
• subgingival colonization was greater in the bur treated group
