Detailed Description
60 patients with AP and extraction indication were included in the study. 30 systemically and orally healthy volunteers were selected as the control group. After access cavity preparation, an initial microbiologic sample(S1) was taken from the root canal. After atraumatic extraction of the tooth, second microbial sample(S2) was taken from the external root surface. After bacterial DNA extraction, 16S rRNA gene primer was designed for sequence analysis. Bacterial community profiling was made by Sanger sequencing of the PCR products. Besides, blood samples were collected from all of the patients. Enzyme-linked immunosorbent assay was used to measure levels of MMP-9 and TNF-α Approximately 450 patients who applied to xxxx University, Faculty of Dentistry, Endodontics Department for routine examination due to apical periodontitis complaints were examined and their demographic characteristics were recorded. Patients who had any acute or chronic inflammatory disease, known infection status, history of trauma or surgical operation within 6 months that may affect MMP-9 levels, pregnant and/or lactating, malignity, morbid obesity, arthritis, immunologic diseases, cardiovascular diseases or use of vitamins with high biotin were not included in the study. Additionally, patients who used antibiotics or anti-inflammatory drugs within the last 6 months, and patients with periodontal disease were excluded from the study. Of these patients, 60 patients with AP and extraction indication (due to restorative causes and lesion size) were included in the study. A total of 30 volunteers who were determined to be systemically and orally healthy (not having AP indication), were included in the study as the control group. The study was conducted between March 2022 and February 2023.

Laboratory Analysis
Time Frame: The study was conducted between March 2022 and February 2023
|
Blood samples were collected from the patients for MMP-9 and TNF-α analysis.
The blood samples taken from the patients in a tube with a gel separator were kept at room temperature for 20-30 minutes to coagulate, and then centrifuged at 1800 g for 10 minutes.

Bacteriological Sampling from the Root Canal System and Outer Root Surface
Time Frame: The study was conducted between March 2022 and February 2023
|
After plaque removal and rubber dam isolation, the operative field was cleaned with 3% hydrogen peroxide and disinfected with 2.5% NaOCl solution.
Then, old coronal restorations if present and carious defects were removed, and an access preparation was completed when the root canal space was properly exposed.
Afterwards, the tooth (including the pulp chamber), clamp and adjacent rubber dam were once again disinfected with 2.5% NaOCl, followed by inactivation with 10% sodium thiosulfate in order to avoid interference with bacteriological sampling.
The working length (WL) was established 1-mm short of the apical foramen with an apex locator (Raypex6; VDW GmbH).

ELISA measurement procedure of MMP-9 and TNF-α levels
Time Frame: The study was conducted between March 2022 and February 2023
|
BT lab branded Human Matrix Metalloproteinase 9 and Human Tumor Necrosis Factor-α ELISA Kits (Shangai, China) were used to measure MMP-9 and TNF-α levels.
The sensitivity of the kits is 15.12 ng/L and 1.520 pg/mL, respectively, and the measuring range of the kit is 30 - 9000 ng/L and 3 - 900 pg/mL, respectively.
The within-run coefficient of variation is < 10%.
In the study, measurements were made using BIO-TEK ELx500 ELISA Reader and BIO-TEK ELx50 (USA) washing devices.
