NCT06307678

Brief Summary

Calcium hydroxide is generally preferred in endodontics as an intracanal medicament because of its antimicrobial and biological effects. However, the antimicrobial effect of calcium hydroxide is limited. The aim of this study was to investigate the effects of calcium silicate-based root canal medicament on the release of RANKL/OPG, TNF-α, PGE-2 and TGF-β1 in root canal treated teeth with periapical lesions.

Outcome Measures

Primary Outcomes (4)

  • preoperative and postoperative levels of RANKL/OPG ratio

    The amounts of cytokines RANKL and OPG were measured using an enzyme-linked immunosorbent assay kit.

  • preoperative and postoperative levels of prostaglandinE2 (PGE2) ratio

    The amounts of PGE2 were measured using an enzyme-linked immunosorbent assay kit.

    one week

  • preoperative and postoperative levels of TNF alpha ratio

    The amounts of TNF alpha were measured using an enzyme-linked immunosorbent assay kit.

    one week

  • preoperative and postoperative levels of TGF beta ratio

    The amounts of TGF beta were measured using an enzyme-linked immunosorbent assay kit.

    one week

Secondary Outcomes (1)

  • dependent variables (sex, age, teeth number, smoking habit)

calcium silicate based medicament

EXPERIMENTAL

Root canal lengths were determined by an electronic apex locator with a 15-K file R25 and R50 Reciproc files were used at working lengths to complete the canal preparation. During instrumentation, the root canals were irrigated with 2 mL 1% NaOCl. To obtain the first samples, 3 sterile paper points were placed into the root canals beyond the 2-mm root apex and were kept in position for 60 seconds. Thereafter, the paper points were cut 4 mm from the tip30. Afterward, root canals were dried with paper points, and calcium silicate based medicament was placed in the canals using a file at a distance of 1 or 2 mm less than the root canal length. Next, the coronal cavities were restored with temporary material. Seven days later, the medication was mechanically removed using a master apical file. Subsequently, root canals were irrigated.The final samples were collected from the interstitial fluid of the apical tissue as previously described.

Drug: Calcium Hydroxide

Interventions

The samples were taken from the interstitial fluid of the apical tissues using 3 paper points before medicament placement. Calcium hydroxide based medicament was placed in the canals using a file at a distance of 1 or 2 mm less than the root canal length. At the second appointment, medicamentswere removed, and second samplingwas performed using the same method. The RANKL/OPG, TNF alpha, TGF beta, PGE2 levels were measured by the enzyme-linked immunosorbent assay, and their ratio was calculated.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Incisor, canine, and premolar teeth that had previously undergone root canal treatment (cases with persistent and secondary disease) and presented with a diagnosis of chronic apical abscess or asymptomatic apical periodontitis were included. Incisor, canine, and premolar teeth with only 1 root canal were included in the study to avoid untreated extra root canals and difficulties in the preparation, obturation, and restoration of molar teeth and to make treatments more standardized.The patients had not used any antibiotics for 3 months before treatment, and patients were obviously free of systemic diseases.

You may not qualify if:

  • Patients were excluded if teeth showed the presence of a root fracture or any swelling, ankyloses, or periodontal pockets deeper than 4 mm. Teeth on which a rubber dam could not be performed were excluded. Patients with allergy to ibuprofen or ciprofloxacin were also excluded.
