Intervention

Procedure:
• Open flap debridement with osteoplasty
Treatment of furcation grade III defect with open flap debridement followed by osteoplasty treatment. Osteoplasty includes altering the bone buccal to the furcation opening to >90 degrees relative to the apico-coronal axis of the tooth.
• Open flap debridement without osteoplasty
Treatment of furcation grade III defect with open flap debridement only.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Sites with no signs of inflammation	Proportion of sites without inflammation, defined as no BoP or PPD>4mm following treatment	12 months after treatment
Primary	Sites with no signs of inflammation	Proportion of sites without inflammation, defined as no BoP or PPD>4mm following treatment	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

Secondary	Loss of clinical attachment level	To assess further loss of clinical attachment level by the use of a periodontal probe	12 months after treatment

Secondary	Number of participants with caries lesions	To assess caries lesions in furcation defects following therapy. Caries lesions are assessed clinically with an explorer as caries (Y/N)	24 months after treatment
Secondary	Radiographic changes	To assess bone loss as measured on standardized radiographs (in mm)	12 months after treatment
Secondary	Radiographic changes	To assess bone loss as measured on standardized radiographs (in mm)	24 months after treatment
