Post Operative Pain and Level of Endotoxins With Calcium Hydroxide and Calcium Hydroxide Mixed With Chlorhexidine in Treating Necrotic Teeth

• Status: Unknown status
• Trial end date: 2018-01-01

Summary

The aim of this prospective in vivo randomized clinical trial to evaluate influence of combination of calcium Hydroxide (CALCIPAST Paste, Poland) and chlorhexidine Gel 2% (Gluco-Chex 2%, Cerkamed, Poland) in comparison to calcium hydroxide paste (CALCIPAST Paste, Poland) as Intracanal Medication on post operative pain (incidence, degree, duration) and reduction of bacterial endotoxins (quantitative) after endodontic treatment in single rooted necrotic teeth.

According to the inclusion criteria the patients enrolled in the study and allocated randomly into three groups either combination of calcium hydroxide paste intracanal medication with 2% chlorhexidine gel. (group A) or calcium hydroxide paste intracanal medication only (group B) or mechanical preparation without intracanal medications (group C) the endodontic treatment is done at two visits.

The samples of endotoxin divided into three groups: after access (S1), after mechanical instrumentations (S2), after removal intracanal medication (S3), all samples taken by a sterile paper points introduced in the root canal for the working length for 60 seconds.

firstly the patient's medical and dental history is taken. the patients assign on informed consent. and then anaesthetized and access cavity performed and root canal preparation is done by Revo-s system then irrigation and intracanal medication placement inside to canal. the patient's record the post operative pain in sheet with NRS after 4, 24, 48 hours and 2 weeks after first visit. the operator will recall the patient to check the records

second visit After 2 weeks from application of ICM, rubber dam will be applied then removal of the temporary dressing, then a sterile paper point (S3) will be introduced into the canals after irrigation and removal of the remnants of the intracanal medicament with the saline solution.

• Removal of the paper sample to determine the endotoxin concentration.

• The canals will be obturated by single cone technique using gutta percha point tapered 0.4% (Gutta percha point, Revo-S MicroMega CO., LTD, France) corresponding to the final apical size of the file and the root canal sealer will be resin sealer (Adseal, META BIOMED CO., LTD, Korea).

• Pain will be assessed by numerical pain rating scale (NRS) after 14 days from the first visit (at the day of the Obturation) before the beginning of Obturation.

• Phase: N/A
