Regenerative endodontic treatment with calcium hydroxide
Regenerative endodontic treatment (RET) performed with procedures of American Association of Endodontics (AAE) in two sessions. At the end of the first session, periapical tissue fluid samples (baseline samples) were collected.
Calcium hydroxide medicament was prepared by mixing with sterile distilled water and then placed in the coronal 1/3 of the root canals.
In the second session (14 days after first treatment), the medicaments in the root canals were carefully removed with 5 ml sterile distilled water irrigation. Periapical tissue fluid samples were obtained from the distal canal using the same protocol as described previously (final samples). Then RET was finished according to the treatment protocol of AAE.
Place the freshly prepared calcium hydroxide in to the root canals
Calcium hydroxide (Merck, Darmstadt, Germany): prepared by mixing with sterile distilled water and then placed in the coronal 1/3 of the root canals.
Regenerative endodontic treatment with double antibiotic paste
Regenerative endodontic treatment (RET) performed with procedures of American Association of Endodontics (AAE) in two sessions. At the end of the first session, periapical tissue fluid samples (baseline samples) were collected.
Double antibiotic paste (DAP) was prepared by mixing same amount of metronidazole and ciprofloxacin powdered antibiotics (1:1) and combined with sterile distilled water to form an ointment. DAP was introduced in roots canals using a lentulo to fill the entire root canal space.
In the second session (14 days after first treatment) after removal of DAP in the root canals, periapical tissue fluid samples were obtained the same protocol as described previously (final samples). Then RET was finished according to the treatment protocol of AAE.
Place the freshly prepared double antibiotic paste in to the root canals
Double antibiotic paste (DAP): metronidazole (Flagyl, Sanofi-Aventis, Turkey) and ciprofloxacin (Cipro, Biofarma, Turkey) powdered antibiotics were stored and sealed in airtight containers. The same amount of each drug powder (1:1) was mixed and the mixed samples were combined with sterile distilled water to form an ointment. DAP was introduced in roots canals using a lentulo to fill the entire root canal space.
Radiographic evaluation
Pre-operative, post-operative and final recall (12th months follow up) standart digital radiographs were taken from patients with film holder. The radiographs saved and transferred to Image J software (version 1.47, National Institutes of Health, Bethesda, MD). The standardized radiographs were further aligned using the TurboReg plugin (Biomedical Imaging Group, Swiss Federal Institute of Technology, Lausanne, Switzerland) within the Image J toolkit to minimize any distortions caused by variability in the angulation.
All images were calibrated according to size #2 SPP (vertical dimension 31 mm, horizontal dimension 41 mm) using the ''set scale'' option in Image J. Thereafter, the root lengths, root width and radiographic root area were measured on both preoperative and final recall images to evaluate treatment outcomes.
Taking standart periapical radiography with film holder
Post-operative periapical radiographs were obtained with Digora Optime SPP system (Soredex Corp., Tuusula, Finland) using intraoral film holders to keep the plates parallel to the long axis of the teeth. A size #2 SPP was used for all exposures. SPPs were exposed with a Gendex Oralix DC dental x-ray unit (Gendex Dental Systems, Milan, Italy) operating at 60 kVp, 7 mA, 0.25 sec. and the plates were scanned immediately after exposure. The clinical and radiographical follow up was performed on 12th months.
Image-J program (version 1.47, National Institutes of Health, Bethesda, MD) with TurboReg plug-in (Biomedical Imaging Group, Swiss Federal Institute of Technology, Lausanne, Switzerland) was used to determine the increase in root length, root width, and radiographic root area at 12th month follow up.
Periapical tissue exudate sample collection and Immunofluorometric assay MMP-8
At the end of the first session, periapical tissue fluid samples (baseline samples) were collected by introducing 3 sterile #45 paper points into the root canal until 2 mm passing through the root apex from the distal canal. After waiting for 1 min, the paper points were withdrawn, the tip was cut from 4 mm and were transferred to sterile Eppendorf tubes. At the beginnign of the second session periapical tissue fluid samples were obtained from the distal canal using the same protocol as described in the first session (final samples).
Baseline and final MMP-8 concentrations were determined by a time-resolved immunofluorometric assay (IFMA). The monoclonal MMP-8 specific antibodies 8708 and 8706 (Oy Medix Biochemica Ab, Espoo, Finland) were used as a catching antibody and a tracer antibody, respectively. The tracer antibody was labeled using europium-chelate
Sample collection for immunofluorometric assay
Periapical exudate samples were collected at the beginning of the RET and at 14th day. MMP-8 levels were measured by immunofluorometric assay (IFMA). Briefly, two monoclonal MMP-8-specific antibodies, 8708 and 8706 (Oy Medix Biochemica Ab, Espoo, Finland) were used as catching antibody and tracer antibody, respectively. Samples were diluted in enzyme buffer (50 mM Tris-HCl, pH 7.5; 0.2 mM NaCl, 1 mM CaCl2). Twenty microlitres of samples and 80 μl of assay buffer (20 mM Tris-HCl, pH 7.5, 0.5 M NaCl, 5 mM CaCl2, 0.5% BSA, 0.05% sodium azide and 20 mg/l diethylenetriaminepentaacetic acid with 2 μg/ml normal mouse serum) were pipetted into the wells. The tracer antibody was labelled using europium chelate. After adding the enhancement solution, fluorescence was measured using a 1234 Delfia Research Fluorometer (Wallac, Turku, Finland).
