Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of furcation grade level	Proportion of sites demonstrating improvement in furcation grade level as measured with Nabers probe	12 months after treatment
Primary	Change of furcation grade level	Proportion of sites demonstrating improvement in furcation grade level as measured with Nabers probe	24 months after treatment
Secondary	Changes in patient-reported quality of life (QoL)	To assess QoL changes related to mouth and teeth prior to therapy to after therapy by the use of "The Oral Impacts on Daily Performance (OIDP)" instrument. Each question is assessed by a 5-point scale; (1) never affected, (2) less than once a month, (3) once or twice a month, (4) once or twice a week; and (5) every or nearly every day. The higher number represents more severe impact on quality of life; e.g. worse outcome.; Each item will be dichotomised yielding the categories (A) affected; including scale categories (2)-(5), and (B) unaffected, including category (1).	Preoperatively compared to 24 months after treatment

Preoperatively compared to 12 months after treatment
Secondary	Changes in defect morphology assessed by CBCT	Cone beam computed tomography will be acquired at baseline, 2 weeks postoperatively and 24 months postoperatively. This outcome measures quantitative morphologic changes in the furcation defects at 24 months	24 months after treatment
Secondary	Changes in pocket probing depth	Changes in pocket probing depth will be measured with a probe	12 months after treatment
Secondary	Changes in pocket probing depth	Changes in pocket probing depth will be measured with a probe	24 months after treatment
Secondary	Changes in PPD	Changes in pocket probing depth will be measured with a probe	12 months after treatment
Secondary	Changes in PPD	Changes in pocket probing depth will be measured with a probe	24 months after treatment
Secondary	Radiographic changes	Standardized intraoral bitewing radiographs will be obtained and compared to baseline radiographs	12 months after treatment
Secondary	Radiographic changes	Standardized intraoral bitewing radiographs will be obtained and compared to baseline radiographs	24 months after treatment
Secondary	Pain following surgery	Pain sensation one week posteoperatively will be recorded on a visual analog scale from 0-10. 0 means no pain sensation, whereas 10 means highest pain imagineable.	Up to 1 week postoperatively
Secondary	Caries assessment	Caries in furcation defect assessed with an explorer will be recorded as (Y/N)	24 months
Secondary	Caries assessment	Caries in furcation defect assessed with an explorer will be recorded as (Y/N)	12 months
