Anaesthetic Efficacy of Lidocaine and Articaine in Inferior Alveolar Nerve Block Combined with Buccal Infiltration in Patients with Irreversible Pulpitis.

Purpose: This prospective, randomized, double-blinded study was conducted to compare the anesthetic efficacy of 2% lidocaine with 1:200,000 epinephrine and 4% articaine with 1:200,000 epinephrine in inferior alveolar nerve block (IANB) combined with buccal infiltration in patients with irreversible pulpitis.

Methods: Group I: Thirty patients received IANB of 2% lidocaine without buccal infiltration. Group II: Thirty patients received IANB of 2% lidocaine followed by buccal infiltration with 2% lidocaine.

Fracture Resistance of Titanium, Chrome-Cobalt, and Gold Alloy as Post and Core Materials: A Comparative Evaluation.

Aim: This study aimed to comparatively evaluate the fracture resistance of different metallic post and core materials.

Materials And Methods: Twenty-four maxillary-central incisors were selected, standardized, and segregated into three groups (GP I-III) ( = 8) based on the type of alloy used for post and core preparation. GP I (gold alloy [Au]), GP II (chrome-cobalt alloy [Co-Cr]), and GP III (titanium alloy [Ti]) were comparatively evaluated for use as post and core materials.

A Comparative Evaluation of Phytic Acid as Final Rinse Solution with Other Chelating Agents for Elimination of Intraradicular Smear: A Scanning Electron Microscopy Study.

Aim: The aim of this study was to compare radicular smear layer removal ability of different solutions of phytic acid (PA) with other chelating agents when used in specific irrigant protocols.

Materials And Methods: Seventy four maxillary central incisors were collected, standardized, and canals were prepared. A total of 5% sodium hypochlorite was used as the initial rinse solution (8mL).
