one of the endpoints to successful SRP is no pocket depths greater than ____ mm5mm
pockets of 4-6 mm benefit from SRP by receiving ___mm pocket reduction and ____ mm attachment gain1.29 pocket reduction; 0.55 mm attachment gain
SRP curette efficicacy of ____ mm (plaque and calculus free)3.73 mm
SRP instrument limit of ___ mm6.21 mm
SRP avg working time per tooth of ___ minutes35 minutes
Waerhaug found that after SRP more than 90% of cases had residual plaque & calculus in pockets greater than _________ mm5mm
Waerhaug found that after SRP more than _________% of cases had residual plaque & calculus in pockets greater than 5 mm90%
Buchanan & Robertson noted that ___ and ____ are more difficult to clean in SRP without a flappremolars & molars
Buchanan & Robertson noted that more than ___% of molar sites had residual calculus after SRP60%
T/F: we can do periodontal surgery if patients have poor oral hygieneFALSE (contraindicated)
Course of action at re-eval: Good OH; minimal inflammation with little or no BOP; pockets generally < 4 mmPeriodontal Maintenance
Course of action at re-eval: Good OH; persistent BOP in multiple sites; Multiple pockets > 5 mmSurgical Periodontal therapy
Course of action at re-eval: Poor OH; persistent BOP & deep pocketsNO SURGERY; get OH in control first
