Brief summary

HYPOTHESIS: There is a difference in mean inter-appointment pain using Triple Antibiotic Paste and Chlorhexidine, in teeth with Symptomatic Apical Periodontitis. The aim of this study is to compare the mean difference in inter-appointment pain in patients with Symptomatic Apical Periodontitis to determine whether a combination of antibiotics such as TAP or simple Chlorhexidine gel is more effective for pain relief at 48 hours after canal preparation in multiple-visit routine Root canal treatment. Therefore, this will help in recommending the most appropriate intracanal medicament to be used in between appointments for effective pain relief.

Interventions

Patients will be divided into two equal groups Group 2 will receive Triple Antibiotic Paste (TAP) as intracanal medicament. TAP contains Ciprofloxacin 500mg, Metronidazole 400mg and Minocycline 100mg in 1:1:1. A powder is made and then mixed with Normal saline to form a paste. Amount administered is approximately 0.5 to 1ml (root canal is filled from root apex till canal orifice) Medicaments are placed inside the Root canal system for at least 1 week between the 1st and 2nd appointment i.e. af

It is removed in the 2nd visit. Medicament is placed by the treating dentist (postgraduate resident in Operative Dentistry and Endodontics) Number of appointments (2 to 3 appointments approximately 1 week apart) Mean pain score at 48 hours after placement of medicament will be recorded.
