A clinical trial to study the effect of palatal root length on the success of maxillary buccal infiltration by open and closed mouth technique

INTERVENTION: Intervention1: Root Canal Treatment under local anesthesia: 1.8ml of 2% lidocaine in 1:80000 adrenaline, will be administered as maxillary buccal infiltration for maxillary 1st molars with symptomatic irreversible pulpitis. Duration of therapy is about an hour. Intervention2: Root canal treatment: Maxillary 1st molars with irreversible pulpitis will be treated with root canal treatment under 2% lidocaine, with 1:80000 adrenaline Control Intervention1: 2% lidocaine with 1:80000 adrenaline in open mouth technique.: In group 1:‐ Maxillary 1st molars with irreversible pulpitis needing root canal treatment, maxillary buccal infiltration will be given in open mouth technique. Control Intervention2: 2% lidocaine in 1:80000 adrenaline in closed mouth technique.: In Group 2:‐ Maxillary 1st molars with irreversible pulpitis needing root canal treatment, maxillary buccal infiltration will be given in closed mouth technique. CONDITION: Health Condition 1: K040‐ Pulpitis PRIMARY OUTCOME: Visual Analogue Scale(VAS)Timepoint: 30 minutes SECONDARY OUTCOME: Visual Analogue Scale(VAS)Timepoint: 2 minutes, 30 minutes INCLUSION CRITERIA: 1)Patients aged 18 to 50 years with symptomatic irreversible pulpitis in maxillary molars. 2)Teeth without gingival recession or existing periodontal disease. 3)Patients without chronic systemic disease. 4)Patients able to understand pain scales.
