Brief summary

The study hypothesis was that "" The placement of different medications after cleaning the teeth will reduce the pain after the procedure in comparison to the teeth where no teeth where no medication was placed after tooth cleaning. The study aimed to assess the efficacy of three intra-canal medicaments on post root canal preparation pain. Eighty patients with single rooted necrotic teeth and symptomatic apical periodontitis were randomly assigned four treatment groups (n=20). The preoperative pain was recorded on Wong-Baker’s FACES Pain Rating Scale. After chemo-mechanical canal preparation intracanal medications were placed: Group-1 (20%calcium hydroxide), Group-2 (2%Chlorhexidine), Group-3 (Tri-antibiotic paste), Group-4 (no medication-control group). Patients were instructed to record pain on Wong-Baker’s FACES Pain Rating Scale at 4, 48,72 and 96 hours, postoperatively

Interventions

Group-1: Received Calcium Hydroxide paste (20%) as intra-canal medicament; Group-2: Received Chlorhexidine gel (2%) gel; Group-3: Received Tri Antibiotic Paste (ciprofloxacin, minocycline, and metronidazole mixture in proportion of 1:1:1 by weight to the final concentration of 0.5 mg/ml) All the aforementioned three interventions will be administered as intra-canal medicaments. The amount of the Calcium hydroxide paste, Chlorhexidine gel, and Tri-antibiotic paste administered is directly propo

Group-1: Received Calcium Hydroxide paste (20%) as intra-canal medicament; Group-2: Received Chlorhexidine gel (2%) gel; Group-3: Received Tri Antibiotic Paste (ciprofloxacin, minocycline, and metronidazole mixture in proportion of 1:1:1 by weight to the final concentration of 0.5 mg/ml) All the aforementioned three interventions will be administered as intra-canal medicaments. The amount of the Calcium hydroxide paste, Chlorhexidine gel, and Tri-antibiotic paste administered is directly proportional to the volume of the intra-canal spaces of the teeth and is typically 0.5-1 ml. The interventions will be administered by the endodontist only once after the completion of cleaning and shaping stage of the root canal treatment procedure. The approximate duration of the procedure will be one hour.

Inclusion criteria

The inclusion criteria were single rooted teeth (anterior and posterior) with symptomatic apical periodontitis and negative response to vitality testing indicating necrotic pulp

Exclusion criteria

non-restorable teeth and teeth having endo-perio lesions, acute or chronic apical abscess, chronic periodontitis or anatomical difficulties like open apices, calcified canals, severe dilacerations, internal/ external root resorption and occlusal interferences were excluded from the study. Additionally, allergic patients, patients taking medicines that could influence pain perception or having serious medical illness, systemic disorders, or immunocompromised diseases like AIDS, HBV were also excluded
