This study is also split mouth
design where half of the mouth is treated with scaling alone the other half with
scaling followed by modified Widman flap surgery. No infection control methods
were administered except local debridement followed by oral hygiene instructions
and three month follow-up prophylaxis.
The results were as follows:
1) Treatment results following scaling versus scaling plus modified Widman
flap surgery were maintained over a 6-1/2 year period.
2) Pocket depth did not change in shallow pockets (1-3mm deep) over 6-1/2
years for either treatment.
3) For pockets 4-6mm deep, both treatments resulted in equally effective
and sustained pocket reduction.
