Calcium hydroxide is advocated as an intracanal medication for various purposes, including prevention of post-treatment symptoms. Calcium hydroxide has a pain-controlling effect at different times when compared to non-intracanal medication . Aim: The aim of the study to compare between postoperative pain after using two formulations of calcium hydroxide intracanal medication with and without iodoform .
The most persuasive factor for a patient to visit a dental health care professional is the existence of odontalgia. Accordingly, the pain after a dental therapy results in demotivation of the patient. Unfortunately, mild to severe pain following a tooth-preserving therapy such as root canal treatment is reported to be experienced by 40% of the patients. The majority of patients with symptomatic necrotic teeth had significant postoperative pain and required analgesic medication to manage this pain. There is a correlation between the intensity of preoperative pain and postoperative pain ,The preoperative pain has a significant influence on postoperative pain. Several strategies are suggested to manage or prevent post instrumentation pain. One of them is insertion of intracanal medicament. The interappointment intracanal medicaments are suggested for disinfection of the infected root canal system in multi-visit endodontic treatment. Calcium hydroxide (Ca(OH)2) is considered as a universal intracanal medicament for this purpose. Additionally, calcium hydroxide is hypothesized to exert a pain-preventing effect indirectly through its antimicrobial and tissue modifying properties . Significantly high healing rates have been shown with short term use of calcium hydroxide Ca(OH)2 in teeth with apical periodontitis. As a temporary root filling, it has been shown to be an effective antimicrobial agent when applied for a minimum of 1 week. Calcium hydroxide is a suitable material of choice as an inter-appointment dressing for teeth diagnosed with pulpal necrosis and apical periodontitis. Calcium hydroxide reduced pain risk than no intracanal medication within the 1-14 days interval as well as triple-antibiotic paste within the first day and was similar to corticosteroid/antibiotics combination. Iodoform has bacteriostatic property by releasing free iodine.Thereby, iodine eliminates the infection of root canal and periapical tissue by precipitating protein and oxidizes essential enzymes. The use of calcium hydroxide-iodoform-silicon-oil paste as nonsurgical approach for treatment of periapical lesions showed a high success rate. As clinicians , one of the most important goals to achieve is reducing the pain of the patient. Up to our knowledge, none of the previous studies investigated the postoperative pain incidence after application of Ca(OH)2 with iodoform as an intracanal medication .

The patient will be anaesthized with Articaine hydrochloride 40 mg/ml + 1/100000 Epinephrine bitartrate solution . Then the rubber dam isolation will be conducted, the access will be opened and then cleaning and shaping will be done by using Protaper Next rotary file system and irrigation by sodium hypochlorite 2.5% by side vented needle, EDTA 17%, sodium hypochlorite and the final rinse by saline where the canal will be dried by absorbent paper point. The application of calcium hydroxide intracanal medication will be done according to the manufacturer instructions then temporization by glass ionomer will be applied .

RECRUITINGMeasuring the severity of postoperative pain in both groups.
Measuring the severity of postoperative pain in both groups. The patients will be informed to record their pain scores in visual analogue scale (VAS) as used by Habib et al. (1990) .The degree of the pain will have numerical value 0= no pain, 1-3= mild pain, 4-6= moderate pain , 7-9= severe pain . The pain score will be recorded at 4 hours . No medication will be prescribed for the patients . They will be instructed to take only Ibuprofen if they experienced pain and it will be recorded in the chart.
