Periodontal Diseases Clinical Trial
Official title:
Flapless Application of Enamel Matrix Derivative in Class II Mandibular Furcation Defects: a Randomized Clinical Trial
Patients diagnosed with stage III or IV periodontitis that exhibit mandibular first or second molars with increased periodontal probing depth (PPD > 4 mm) and class II buccal mandibular furcation defects (horizontal probing depth of >= 3 mm ) will be recruited. This study will be a non-inferiority, prospective, randomized, double-blind controlled clinical trial with a parallel design. Patient will be recruited from the clinics of the School of Dentistry at the Aristotle University of Thessaloniki and private dental practices in Thessaloniki, Greece. Initially, non-surgical periodontal treatment will be performed through scaling and root planning in combination with oral hygiene instructions and motivation. The re-evaluation will be performed 4-6 weeks following the treatment and the patients who meet the inclusion criteria will be included in the study. Patients will be randomly allocated at a 1:1 ratio to either subgingival debridement and flapless application of EMD (test group) into the affected furcation defect or to periodontal surgery in combination with EMD application (control group). Periodontal and radiographic parameters, patient reported outcomes, oral cavity measurements and gingival crevicular fluid will be collected before as well as up to 9 months following the treatment.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Periodontal probing pocket depth (PPD) change | Changes in pocket probing depth will be measured using a periodontal probe. The depth of the sulcus will be assessed by gently inserting a graduated periodontal probe until resistance is encountered at the base of the sulcus. The depth from the free gingival margin to the base of the sulcus is measured in millimeters and represents PPD. | 9 months after treatment | |
Secondary | Horizontal and vertical furcation involvement change. | Changes in horizontal and vertical furcation involvement will be measured using a periodontal probe. | 9 months after treatment | |
Secondary | Periodontal clinical attachment level (CAL) change. | Changes in clinical attachment level will be measured using a periodontal probe. | 9 months after treatment | |
Secondary | Bleeding on Probing (BOP) change | Bleeding on Probing will be tested using a periodontal probe that is carefully introduced to the bottom of the pocket gently. | 9 months after treatment | |
Secondary | Gingival recession (REC) change | Changes in gingival recession will be measured using a periodontal probe. | 9 months after treatment | |
Secondary | Furcation involvement grade change | Proportion of sites demonstrating change in furcation grade level as measured with Nabers probe | 9 months after treatment | |
Secondary | Radiographic defect depth, height, root trunk and width. | Assessment of the defect depth, height, root trunk and width using Cone-beam computed tomography systems (CBCT) and periapical radiographs and subtraction radiography | 9 months after treatment | |
Secondary | Levels of markers related to periodontal disease activity, inflammation as well as regeneration in the GCF. | The levels of markers will be assessed using gingival crevicular fluid (GCF) and analyzed with multiplex assays (in pg or ng based on the assays) | 9 months after treatment | |
Secondary | Patient-reported outcome measures | Patient-reported outcome measures using Visual Analogue Scales (VAS) Visual analogue Scale: range from 0 mm "no", to 100 mm," the worst possible" | 9 months after treatment | |
Secondary | Oral health-related quality of life | Oral health-related quality of life measures using OHIP-14 (Greek version) The OHIP-14 captures seven domains of OHRQoL with two items per domain: functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap.
The responses are rated on a 5-point Likert scale: 0 = never; 1 = hardly ever; 2 = occasionally; 3 = fairly often; 4 = very often/every day. The OHIP-14 scores can range from 0 to 56 and are calculated by summing the ordinal values for the 14 items. |
