About this study

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

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

cryotherapy with sterile saline at 2.5ºC

Procedure

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

Other names: iced intracanal saline, intracanal cryotherapy

intaoral cryotherapy

Procedure

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

Both intracanal and intraoral cryotherapy

Procedure

Canal is irrigated with iced saline for 5 minutes before obturation . Root canal is obturated and coronal restoration is done. Then, application of intraoral cryotherapy is performed by ice sticks for 30 minutes.

Low Level Laser Therapy

Device

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

Other names: photobiomodulation, LLLT, cold lasers

Control (Standard treatment)

Procedure

, all occlusal contacts were reduced by 1 mm

Other names: occlusal reduction

Primary outcomes

post operative pain

Time frame: preoperative, after 24 hours, on the third , fifth, one week & two weeks after treatment

post operative pain and pain on percussion is tested using visual analogue scale
