Comparing the Effect of Different Intracanal Dressing on Failed Root Canal Treated Cases on Periapical Healing

Comparison of the Effects of Different Natural and Synthetic Intracanal Medicaments on the Healing of Periapical Lesion in Retreatment Cases (A Randomized Clinical Trial)

• Status: Completed
• Phase: Phase 2
• Study type: Interventional
• Enrollment: 60 (actual)
• Sponsor: Ain Shams University · Academic / Other

• Age: 20 Years – 60 Years
• Healthy volunteers: Accepted

Summary

The goal of this clinical trial is to compare the effects of different intracanal medication between endodontic retreatment visits in previously failed root canal treatment patients (single root canal anteriors or premolars teeth). The main question it aims to answer are: * Is natural and synthetic intracanal Medicament effective in reducing or complete healing of Periapical lesions or not? the researchers will compare the effect of different intracanal dressing including: * nanocurcumin gel * curcumin gel * ciprofloxacin +ibuprofen gel * calcium hydroxide Paste as control group in between the endodontic retreatment visits to see if these medicaments work well on periapical lesion healing this outcome measured by Cone beam CT at base and after 1 year follow up period

Conditions

• Periapical Disease

Interventions

Type	Name	Description
DRUG	nanocurcumin gel	firstly patient anesthetized, rubber dam isolation , disinfect the crown with 10%H2O2, saline then sodium hypochlorite solution 2.5% then 5% sodium thiosulphate solution to inhibit the effect of NaOHCl then removal of old coronal restoration, disinfection of pulp chamber by the same previous protocol removal of old root canal filling with gates glidden drills and H files , taken first sample S1 from canal with paper point after using saline wash and scrubbing the canal wall the paper points left for 1 min in the canal then preparation of canal with edge endo files till size 45 taper 0.4 and NaOHCL 2.5% between each file and the next finally 5% sodium thiosulphate to inhibit the antibacterial effect of sodium hypochlorite irrigation then saline irrigation and scrubbing the canal wall and placement of paper points for 1min to taken second sample S2, then dryness of canal and placement of nanocurcumin gel until shown fill the canal under magnification and by using lentulospirals
DRUG	Curcumin Gel	firstly patient anesthetized, rubber dam isolation , disinfect the crown with 10%H2O2, saline then sodium hypochlorite solution 2.5% then 5% sodium thiosulphate solution to inhibit the effect of NaOHCl then removal of old coronal restoration, disinfection of pulp chamber by the same previous protocol removal of old root canal filling with gates glidden drills and H files , taken first sample S1 from canal with paper point after using saline wash and scrubbing the canal wall the paper points left for 1 min in the canal then preparation of canal with edge endo files till size 45 taper 0.4 and NaOHCL 2.5% between each file and the next finally 5% sodium thiosulphate to inhibit the antibacterial effect of sodium hypochlorite irrigation then saline irrigation and scrubbing the canal wall and placement of paper points for 1min to taken second sample S2, then dryness of canal and placement of curcumin gel until shown fill the canal under magnification and by using lentulospirals
DRUG	Ciprofloxacin 500 mg +ibuprofen 400mg	firstly patient anesthetized, rubber dam isolation , disinfect the crown with 10%H2O2, saline then sodium hypochlorite solution 2.5% then 5% sodium thiosulphate solution to inhibit the effect of NaOHCl then removal of old coronal restoration, disinfection of pulp chamber by the same previous protocol removal of old root canal filling with gates glidden drills and H files , taken first sample S1 from canal with paper point after using saline wash and scrubbing the canal wall the paper points left for 1 min in the canal then preparation of canal with edge endo files till size 45 taper 0.4 and NaOHCL 2.5 % between each file and the next finally 5% sodium thiosulphate to inhibit the antibacterial effect of sodium hypochlorite irrigation then saline irrigation and scrubbing the canal wall and placement of paper points for 1min to taken second sample S2, then dryness of canal and placement of ciprofloxacin + ibuprofen gel until fill the canal under magnification and by using lentulospirals
DRUG	Metapaste [calcium hydroxide paste (control group)]	firstly patient anesthetized, rubber dam isolation , disinfect the crown with 10%H2O2, saline then sodium hypochlorite solution 2.5% then 5% sodium thiosulphate solution to inhibit the effect of NaOHCl then removal of old coronal restoration, disinfection of pulp chamber by the same previous protocol removal of old root canal filling with gates glidden drills and H files , taken first sample S1 from canal with paper point after using saline wash and scrubbing the canal wall the paper points left for 1 min in the canal then preparation of canal with edge endo files till size 45 taper 0.4 and NaOHCL 2.5 % between each file and the next finally 5% sodium thiosulphate to inhibit the antibacterial effect of sodium hypochlorite irrigation then saline irrigation and scrubbing the canal wall and placement of paper points for 1min to taken second sample S2, then dryness of canal and placement of calcium hydroxide paste until fill the canal under magnification by using lentulospirals
