In Vivo Comparative Study of Calcium Hydroxide and Triple Antibiotic Paste in Intracanal Medicament in Emergency Pain Reduction

Before commencing treatment, the complete procedure was explained to the patients and consent was obtained. Local anesthesia was administered, and the tooth was isolated under rubber dam. Access cavity preparation was done, and canals were explored using endodontic explorer (DG-16,). Working length was determined with No. 15 K-files using apex locater and was confirmed with radiovisiography . Cleaning and shaping were along with copious irrigation using 3% NaOCl and 0.9% saline . Canals will be dried and one of the following two medicaments will be inserted into the canals in random sequences

Group 1 :Calcium Hydroxide:

CH was placed as an intracanal medicament. Atotal of 100 mg of CH powder was dispensed and mixed with one drop of pro-pylene glycol on a clean and dry glass slab to prepare a thick paste-like consistency. This paste was carried into the canal , and access opening was restored temporarily with temporary cement

Group 2: Triple antibiotic paste:

It was prepared by removing the coating and crushing of antibiotic ciprofloxacin500mg,metronidazole 400mg,, and clindamycin tablets separately using a mortar and pestle. The crushed powder was passed through a fine sieve to remove heavy filler particles and obtain a fine powder. The ciprofloxacin, metronidazole, and clindamycin powders thus obtained were weighed separately and mixed in a 1:3 proportions respectively,to obtain triple antiobiotic mixture.A total 100 mg of this Ta mixture was dispensed and mixed with one drop of propylene glycol to get a thick paste-like consistency. This paste was placed gently compacted into the canal , and access opening was restored with temporary cement Before dismissal ,no antiobiotics will be prescribed and the patients who had been taking antibiotics will be recorded.Patient will be requested to stop antibiotics.They will be requested to stop analgesic.The preoperative pain experienced on the previous night will be recorded using visual analogue scale.Patient will be then instructed to record the degree of pain experienced after 2nd day ,7th day and 15 day postoperatively
