The effect of ketorolac buccal infiltration on postoperative endodontic pain: a prospective, double-blind, randomized, controlled clinical trial.

Objectives: The aim of the present double-blind, randomized, controlled clinical trial was to evaluate the effect of ketorolac buccal infiltration of on postendodontic pain of patients with symptomatic irreversible pulpitis in mandibular first/second molars.

Method And Materials: Sixty patients meeting the inclusion criteria were evaluated. After receiving a standard inferior alveolar nerve block (IANB) followed by a buccal infiltration injection with lidocaine, half of the participants randomly received a supplemental buccal infiltration of 30 mg/mL ketorolac tromethamine and the other half received a buccal infiltration of normal saline adjacent to the periapical region of the tooth being treated.

Formation of biofilm on various implant abutment materials.

The characteristics of prosthetic implant components, such as the type, material, and surface roughness of abutments, can affect biofilm formation. Since an ideal abutment surface for the reduction of bacterial adhesion has yet to be found, this in vitro study aimed to quantify biofilm formation on laser-treated titanium, zirconia, and titanium surfaces. Sterile titanium, zirconia, and laser-treated titanium discs were placed in sterile 48-well plates.

Correlation Between Bone and Soft Tissue Thickness in Maxillary Anterior Teeth.

Objectives: The purpose of this study was to determine buccal bone and soft tissue thicknesses and their correlation in the maxillary anterior region using cone beam computed tomography (CBCT).

Materials And Methods: In this cross sectional study, 330 sound maxillary incisors in 60 patients with a mean age of 37.5 years were assessed by CBCT scans.

Morphology, proliferation, and gene expression of gingival fibroblasts on Laser-Lok, titanium, and zirconia surfaces.

Soft tissue seal plays a critical role in long-term success of dental implants, and the effects of implant surface treatments such as laser ablation have been a topic of particular interest in this respect. Considering the existing controversy regarding soft tissue behavior in contact with implant surfaces, this study sought to assess the morphology, proliferation, and gene expression of human gingival fibroblasts (HGFs) on different abutment surfaces. In this in vitro, experimental study, HGFs were cultured on 45 discs (Laser-Lok, titanium, and zirconia).

Effect of a procedural video CD and study guide on the practical fixed prosthodontic performance of Iranian dental students.

Dental students in programs around the world typically pass preclinical courses before entering the clinic and working on actual patients. Since fixed prosthodontics is a preclinical course that requires a great deal of effort, students may experience a substantial amount of stress that may affect their self-confidence and/or clinical performance. In this study, an instructional video CD (VCD) and study guide depicting the step-by-step procedures involved in a metal-ceramic tooth preparation and provisional crown fabrication was prepared.
