About

This study compare the effect of applying ice after single visit endodontic treatment with lasers to reduce post operative pain .

Full description

one of the most popular complications after single visit endodontic treatment is pain either spontaneous or on biting so in this study we choose one of the most difficult and challenging cases " Hot tooth " to compare lasers and cryotherapy different applications to reduce post operative pain after single visit endodontic treatment

Enrollment: 45 patients

Sex: All

Ages: 18 to 40 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• • Vital teeth display symptomatic apical periodontitis (Symptomatic apical periodontitis was determined based on the clinical symptoms of severe preoperative pain (visual analogue scale [VAS] > 60) and severe percussion pain (VAS > 60).

  • Teeth, with a periapical index score (PAI) of 2 or 3 indicating small changes in bone structure and slight mineral loss respectively.
  • Mobility less than 1 mm in either direction.
  • Absence of periodontal pocket around the tooth.
  • Symptomatic pulpitis with spontaneous pain or lingered by cold or heat.
  • Teeth without pus or inflammatory exudates draining through the canal.
  • Teeth without anatomic variations

Exclusion criteria

• • Patient with any systemic disease.

  • Immunocompromised patients.
  • Pregnant or lactating patients.
  • Apparently narrow roots in which apical preparation with the #40 file would be overzealous.
  • Retreatment cases.
  • Necrotic painful teeth with absence of sinus tract for drainage.
  • Patients on analgesics or sedative medication up to 6 hours before treatment

---

45 participants in 5 patient groups

control Group

Active Comparator group

Description:

all occlusal contacts are reduced by 1 mm

Treatment:

Procedure: Control (Standard treatment)

intracanal cryotherapy

Active Comparator group

Description:

the root canals are given a final irrigation with 20 mL cold (2.5oC) saline solution for 5 minutes

Treatment:

Procedure: cryotherapy with sterile saline at 2.5ºC

intraoral cryotherapy group

Active Comparator group

Description:

ice sticks (wrapped in sterile gauze if needed) using plastic pipette droppers filled with freezing sterile water are placed intraorally in the mouth on the apices of the treated tooth on both buccal and palatal sides for 30 minutes

Treatment:

Procedure: intaoral cryotherapy

Both intracanal and intraoral cryotherapy

Active Comparator group

Description:

the root canals are given a final irrigation with 20 mL cold (2.5oC) saline solution for 5 minutes , the canal is obturated and then ice sticks (wrapped in sterile gauze if needed) using plastic pipette droppers filled with freezing sterile water are placed intraorally in the mouth on the apices of the treated tooth on both buccal and palatal sides for 30 minutes.

Treatment:

Procedure: Both intracanal and intraoral cryotherapy

Low Level Laser Therapy

Active Comparator group

Description:

laser irradiation on the soft tissues covering the apices of the tooth on both buccal and palatal surfaces respectively.

Treatment:

Device: Low Level Laser Therapy
