Osteoplasty in Conjunction With Surgical Treatment of Mandibular Grade II Furcation Defects

University of Oslo

Overview

Teeth with furcation grade II defects will be treated with open flap debridement, with or without osteoplasty. The study is designed to examine the effect of osteoplasty in the treatment of teeth with furcation grade II defects with open flap debridement.

Interventions

Open flap debridement with osteoplastyPROCEDURE

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.

Open flap debridement without osteoplastyPROCEDURE

Treatment of furcation grade II defect with open flap debridement only.

Outcomes

Primary Outcomes

Sites with no signs of inflammation

Proportion of sites without inflammation, defined as no BoP or PPD\>4mm following treatment

Time frame: 12 months after treatment

Sites with no signs of inflammation

Proportion of sites without inflammation, defined as no BoP or PPD\>4mm following treatment

Time frame: 24 months after treatment

Secondary Outcomes

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)

Time frame: Preoperatively compared to 24 months after treatment

Loss of clinical attachment level

To assess further loss of clinical attachment Level vertically and horizontally, and deterioration of furcation grade Level (grade II to III)
