Background & Objective: furcation involvement occurs in the term of chronic periodontitis, and gives the involved tooth worse prognosis, so that it represents a problem for diagnosis and treatment.

The aim of this study was to compare clinically the surgical treatment of second degree- furcal involvement in mandiblur molars (that each of them has one furcation), using Er:YAG laser versus conventional surgery.

Materials & Methods: 20 second degree- furcal involvements in mandibular first or second molars were randomizely treated either surgically with Er:YAG laser (120 m J\ pulse, 15 Hz) with water irrigation (test group), or surgically with manual instruments (control group).

Clinical assessments were evaluated at baseline, then 3 months postoperatively, included: Vertical probing depth (PD), gingival recession (GR), clinical attachment level (CAL), horizontal probing depth (HOD), and degree of furcation involvement (FI).

Index of postoperative pain was evaluated according to (VAS), and (NAS) scales 24 hours and 48 hours after the surgical treatment.

Results: Clinical study revealed significant improvements in PD and HOD, considerable gain in CAL, with no significant differences between the two study groups.

The control group showed a significant improvement in GR, whereas laser surgical treatment was associated with increasing in GR.

The two groups did not show statistically differences in postoperative pain 24, 48 hours after surgery.

Conclusion: Surgical treatment with Er:YAG laser did not show superiority in achieving required improvements in PD, CAL and HOD scores, so that in the required milding of postoperative pain; whereas conventional surgery resulted in the highest decrease in GR scores
