Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Open flap debridement with osteoplasty
In this arm, periodontal surgery consists of open flap debridement followed by osteoplasty in the furcation entrance area.
|
Treatment of furcation grade II 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 toot.
Treatment of furcation grade II defect with open flap debridement only.
|
ACTIVE_COMPARATOR: Open flap debridement without osteoplasty
In this arm, periodontal surgery consists of open flap debridement only.
No osteoplasty will be performed.
|
Treatment of furcation grade II 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 toot.
Treatment of furcation grade II defect with open flap debridement only.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in patient-reported quality of life (QoL)
Time Frame: Preoperatively compared to 24 months after treatment
|
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) |
