A Novel Surgical Procedure for Er:YAG Laser-Assisted Periodontal Regenerative Therapy: Case Series.
Int J Periodontics Restorative Dent. 2016 Jul-Aug;36(4):507-15. doi: 10.11607/prd.2515.
Abstract
The
objective of this study was to evaluate an Er:YAG laser (ErL)
application for periodontal regenerative surgery in angular bone defects
at nine sites in six patients. Debridement was thoroughly performed
using a combination of curettage with a Gracey-type curette and ErL
irradiation at a panel setting of 70 mJ/pulse and 20 Hz with sterile
saline spray. After applying an enamel matrix derivative and autogenous
bone grafting, ErL was used to form a blood clot coagulation on the
grafted bone surface at 50 mJ/pulse and 20 Hz without water spray for
approximately 30 seconds. Twelve months after surgery the mean probing
depth had improved from 6.2 mm to 2.0 mm, the mean clinical attachment
level had reduced from 7.5 mm to 3.4 mm, and bleeding on probing had
improved from (+) to (-). Mean intrabony defect depth decreased from 6.0
mm before surgery to 1.0 mm 12 months after surgery. A novel procedure
for periodontal regenerative surgery applying ErL irradiation for
thorough decontamination during debridement as well as blood coagulation
following autogenous bone grafting seems to have achieved favorable and
stable healing of periodontal pockets with significant clinical
improvement and desirable regeneration of angular bone defects,
including one-wall defects.
