Non-surgical vs. Surgical Therapy for Periodontal Furcations
Furcation Defects, Periodontitis, Surgical Procedure, Unspecified
About this trial
This is an interventional treatment trial for Furcation Defects
Eligibility Criteria
Inclusion Criteria:
- Minimum of 12 teeth present
- Diagnosis of Severe Periodontitis stage III or IV
- At least one maxillary/ mandibular molar with: i) degree III horizontal furcation involvement (at least between 2 roots for maxillary molars) , ii) class B vertical furcation involvement (bone loss up to the middle third of root cones), iii) residual probing pocket depths > 5 mm in furcation area, iv) maximum mobility degree Iand v) not already accessible for self-performed oral hygiene
- Received a course of non-surgical periodontal therapy within the past six months
Exclusion Criteria:
Patient:
- Full mouth plaque score > 30%
- A course of antibiotics within the past 3 months
- Pregnant/lactating women
- Relevant medical history as evaluated by the examining clinician which may have the potential to affect periodontal surgical treatment
- Individuals on long-standing (2 or above years) supportive periodontal therapy (SPT) management plans
Molar affected by FI:
- Ongoing endodontic pathology affecting the furcation involved molar, as judged by the examining clinician
- Previous periodontal surgical treatment to the furcation affected molar within the previous 5 years
- Endodontically treated molar tooth without a full coverage restoration
- 'Unrestorable' molar tooth (lacking adequate tooth structure to provide a restoration) as deemed by the examining clinician.
- Molar tooth acting as a bridge abutment
- The presence of occlusal dysfunction as assessed by the examining clinician

Experimental
Non-Surgical Periodontal treatment (NSPT)
Surgical Periodontal treatment/ Open Flap Debridement (OFD)
Half of the study participants (controls) will be randomised to receive continued non-surgical periodontal treatment (NSPT). All treatment will be carried out by the same therapist in each centre, including oral hygiene.
The other half of the study participants (test) will be randomised to receive surgical periodontal treatment in the form of open flap debridement (OFD). The aim of the surgery will be to achieve thorough debridement of the furcation area and (if possible) improve accessibility for patient-performed hygiene in the furcation area. Some of the included maxillary molars may have additional FI on the same tooth (for example, grade III FI buccal to mesial and grade I, II or III distal). In this occurrence, the other furcation will be treated according to judgment by the treating clinician. We anticipate that, based on inclusion criteria, the majority of cases will have multiple grade III FI.
