| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Open flap debridement with osteoplasty | Experimental | In this arm, periodontal surgery consists of open flap debridement followed by osteoplasty in the furcation entrance area. |
|
| Open flap debridement without osteoplasty | Active Comparator | In this arm, periodontal surgery consists of open flap debridement only. No osteoplasty will be performed. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Open flap debridement with osteoplasty | Procedure | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Sites with no signs of inflammation | Proportion of sites without inflammation, defined as no BoP or PPD>4mm following treatment | 12 months after treatment |
| Sites with no signs of inflammation | Proportion of sites without inflammation, defined as no BoP or PPD>4mm following treatment | 24 months after treatment |
| Measure | Description | Time Frame |
|---|---|---|
| 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) |
