NCT05603988

Brief Summary

This clinical trial will be conducted to evaluate the amount of Il-8 expression before and after the application of intracanal irradiation with diode laser 980 nm versus placebo in failed endodontic cases with periapical lesions.

Outcome Measures

Primary Outcomes (1)

  • quantification of IL-8

    \- After collection of all the samples, quantification of IL-8 will be determined using ELISA kit before (S-1), after chemo-mechanical preparation (S-2), after intracanal irradiation or placebo effect (S-3) and last after one week of the treatment (S-4). The kit is used according to the manufacturer's recommendations.

    one week

Secondary Outcomes (1)

  • Postoperative pain

    6, 12, 24 hours and 7 days

Study Arms (2)

Placebo group

PLACEBO COMPARATOR

• Mock laser application (Placebo group): The fiber optic tip will be inserted inside the root canal, mimicking the laser irradiation group, but not activated

Other: Placebo

Diode Laser group

OTHER

Intracanal Diode laser application

Device: Intracanal Diode laser irradiation

Interventions

After endodontic retreatment, root canals will be irradiated with a 980 nm diode laser coupled with optical fibre 200 μm (Litemedics, Italy) with setting 1.2-watt power, in pulsed mode. The irradiation protocol will be of 5-sec irradiation followed by a 10-sec pause, which constituted one lasing cycle. The lasing cycle will be performed four times for each tooth. The tip will be positioned 1 mm short of the apex. Followed by activation during which it will be slowly dragged at a speed of approximately 2 mm/ sec in a way that the root canals will be irradiated from the apical to the coronal portion, in a helicoidal movement touching the canal walls.

Eligibility Criteria

Age18 Years - 35 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • failed previously treated endodontic single-rooted teeth with chronic periapical lesions; with radiographic evidence of periapical radiolucency of not less than 1 cm diameter will be selected.
  • Teeth with straight root canals.
  • No contributory medical history.
  • No previous administration of analgesics and/or antibiotics within the previous 2 weeks.

You may not qualify if:

  • Retreatment cases with complications such as separated instruments, perforations, ledges, resorption, transportation, calcifications, immature apices and over fillings.
  • Teeth with curved roots.
  • Swelling or sinus tract.
  • Mutilated teeth that interfere with proper isolation and seal between visits.
  • Subjects with generalized periodontitis, or if the tooth has a probing depth of more than 3 mm.
  • Subjects with uncontrolled diabetes or debilitating diseases.
  • Pregnant or nursing females.
  • Systemic disorders that necessitate antibiotic prophylaxis or prevent the use of Ibuprofen.
