•Purpose: To compare 2 incision techniques, papilla base incision (PBI) and Sulcular incision (IS) in terms of papilla height and recession changes.

•N= 24 patients needs endodontic surgery in single tooth.

•All surgeries performed by 1 oral surgeon using surgical microscope.

•A mucoperiosteal triangular flap elevated, horizontal incision extended from vestibular aspect from the mesial tooth and distal aspect of the distal one.

•PBI consists of 1 horizontal incision at the base of the papilla in the lingual direction and 0.5-1mm in the crestal bone direction.

•After flap elevation, lesion removed and root end resected 2.5-3mm  of the apex and sealed with MTA.

•Measurements were taken by 1 blinded experienced operator.

Most highlighted Results:

• Measurements were taken at baseline and 12 months after surgery. 

•PBI group showed decrease in the mesial and distal aspects of papillary height as well as in the IS group, however, differences were not significant .  •No differences seen in recession change between groups.

Clinical significance:

PBI and IS treatment approaches were comparable in terms of soft tissue healing, as measured through gingival recession and papilla height evaluation 1 year after surgery.
