Brief summary

This study evaluates the role of propolis paste as compared to calcium hydroxide (when used as intracanal medication) in prevention and treatment of pain after root canal treatment in necrotic (infected) teeth. Half of the participants will receive calcium hydroxide, while the other half will receive propolis.

Detailed description

Propolis is a developing herbal medicament used in various aspects on dentistry. it is extremely biocompatible; has flavanoids; which acts as anti-inflammatory and antimicrobial components. Calcium hydroxide is a synthetic medication which is antibacterial

Interventions

DRUGPropolis

it is a natural product obtained from beehive. it has been evaluated for biocompatibility and toxicity; and it is found that it is extremely biocompatible material. In our study, propolis powder will be mixed with saline in a ratio of 1 : 1.5 (propolis powder(wt) / saline(vol)) to form paste; and inserted into the root canals. it will be inserted once and will remain in root canals for 4 days.

DRUGCalcium Hydroxide

it is a synthetic antimicrobial intracanal medicament and gold standard to which other medicaments are being compared. approximately 150 mg of calcium hydroxide paste will be inserted in the root canal. it will be inserted only once and will remain in root canals for 4 days.

Pain Intensity Measure: Visual Analogue Pain Scale

Self recorded pain intensity by the patients at 4 hours, 12 hours, day 2, day 3 and day 4 after root canal preparation and intracanal medicament insertion (first visit). Pain intensity recorded on a Visual Analogue Scale from 0 to 100. Patients who experience no or mild pain; and do not require analgesic will record their pain intensity from 0 to 24. Patients who experience moderate pain; and require Over-the-counter analgesic will record pain intensity from 25 to 49. Patients who experience severe pain; and require use of codeine containing medicine will record their pain intensity from 50 to 74. Patients who experience extreme pain, and no medicine is able to relieve their pain will record pain intensity from 75 to 100. lower pain score (intensity) is a better outcome as compared to higher pain intensity (score)

Time frame: 4 hours, 12 hours, day 2, day 3 and day 4

Population: Out of 80 patients, 12 did not return for follow-up; and no contact could be established with them. Out of these 12 patients, 7 belong to control group and 5 belong to experimental group. Hence, 33 patients in control group and 35 patients in experimental group could be analyzed
