In the present study, fourteen patients (5 males and 9 females). Their age ranged from 38 to 53 (mean age was 43.8 rears). They were chosen as having nearly similar defects, such that twenty eight infrabony defects were selected.
(RVG) system were used for radiographic films to be taken. Bite blocks were prepared for every patient for standardized radiographs.
Four weeks, after defect debridement, the selected defects were reevaluated and measured such that only defects with pocket depth measuring ≥5mm were included in this study.
The twenty eight defects were divided into four groups, the first group has open flap debridement only, the second group has open flap debridement then soft laser irradiation, the third group received (DFDBA) after open flap debridement while the last group has combined therapy using both (DFDBA) and soft laser irradiation following the same surgical step.
Intrasulcular incision was made for the defects, all intrabony defects were debrided, then the (DFDBA) and soft laser irradiation were applied according to the chosen group, then the wounds were closed with black silk sutures and packed for one week.
Doxycycline 200 mg was prescribed for each patient the day of surgery, then 100 mg daily for ten days and antiseptol mouth wash was also prescribed for four weeks postoperatively. Inter-dental toothbrushes were prescribed after four weeks to avoid plaque accumulation in addition to the routine tooth brushing. Every patient was followed up clinically for six months postoperatively (weekly for one month, then monthly for five months).
Pocket depth and clinical attachment level were measured while alveolar bone level and bone density were radio graphically evaluated at baseline and six months postoperatively. Statistical analysis of these recorded measurements revealed that there were significant reduction in pocket depth, gain in clinical attachment level, alveolar bone level and bone density, in all the treated groups. Moreover, at six months, there were significant difference between the first group and the other three groups with insignificant difference between them as regards the last mentioned clinical parameters.
