The aim of this prospective, randomized, parallel arm, blind, controlled clinical trial is to compare the clinical and radiographic outcomes following regenerative treatment of intrabony periodontal defects using a Minimally Invasive Non-Surgical Technique (MINST) with or without the application of Enamel Matrix Derivative (EMD)
The hypothesis is that the adjunctive application of EMD will enhance the clinical and radiographic results of minimally invasive non- surgical treatment of intrabony defects. Radiographic bone fill will be the primary outcome of the research, whereas CAL gain and PD reduction will constitute the secondary outcomes.

Show Detailed Description
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||40 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||A software (www.randomizer.org) will be used by one of the investigators who will not participate in the clinical and radiographic measurements nor the therapeutic intervention, to generate a block randomization. Thus, participants will be randomized in one of the two groups in a way that there is no difference between the two groups regarding the initial depth of the intrabony defect. In patients with more than one intrabony defects meeting the inclusion criteria, a second randomization scheme with the same software will take place, to determine which will be included. The randomization results will be placed in sealed envelopes accessible only to the principal investigator and opened for each patient after the end of MINST to determine if EMD will be applied or not.|

Minimally invasive non-surgical technique (MINST): Root instrumentation under local anesthesia using specific hand instruments (micro- curettes) and delicate piezon ultrasonic instruments in the area of intraosseous defect.
Minimally invasive non-surgical technique (MINST) for the treatment of intrabony defects has been compared with minimally invasive surgical treatment of these defects and has shown to achieve similar beneficial clinical results. In this study MINST will be used as the control treatment.
Active Comparator: MINST with EMD
Minimally invasive non-surgical technique (MINST) with application of Enamel Matrix Derivative (EMD): Root instrumentation under local anesthesia using micro- curettes and delicate piezon ultrasonic instruments in the area of intraosseous defect. Experimental intervention by application of EDTA gel for 2 minutes on the root surface of the involved tooth, followed by rinsing with saline, drying and application of Enamel Matrix Derivative gel, to fill the defect.
Procedure: MINST with EMD
Enamel matrix derivative (EMD) has been widely used in the surgical treatment of periodontal intrabony defects, using a minimally invasive surgical technique (MINST). Recent studies have suggested that this product could also be used in the non-surgical treatment of intrabony defects using a minimally invasive technique with very good results. This study will evaluate the effect of enamel matrix derivative in the non-surgical treatment of periodontal intrabony defects when a minimally invasive technique is used. Besides clinical measurements, radiographic analysis will also be performed to evaluate the treatment results.
- Radiographic bone fill [ Time Frame: Change from baseline to 12 months ]Bone level in the intrabony defect
- Clinical attachment gain [ Time Frame: Change from baseline to 12 months ]Clinical attachment level of intrabony defect measured in millimeters
- Pocket depth reduction [ Time Frame: Change from baseline to 12 months ]Pocket depth of intrabony defect measured in millimeters
- Recession [ Time Frame: Change from baseline to 12 months ]Recession depth calculated as the difference of clinical attachment level minus probing depth.
- Full mouth plaque score [ Time Frame: Change from baseline to 12 months ]Percentage of tooth sites with detectable plaque
- Full mouth bleeding score [ Time Frame: Change from baseline to 12 months ]Percentage of tooth sites with bleeding when a periodontal probe is traced along the gingival margin
- Distance from the CEJ or the margin of a restoration to the bottom of the defect (CEJ-BD) [ Time Frame: Change from baseline to 12 months ]Measured in millimeters
- Distance from the Cementoenamel Junction to the bone crest (CEJ-BC) [ Time Frame: Change from baseline to 12 months ]Measured in millimeters
- Depth of the intraosseous defect [ Time Frame: Change from baseline to 12 months ]Distance from the bone crest to the bottom of the defect (BC-BD) measured in millimeters
- Angle of the intraosseous defect [ Time Frame: Change from baseline to 12 months ]Angle will be determined by the line defined by the root surface of the involved tooth and the line defined by the bone wall of the defect
