Comparison of Needle Depth Techniques for the Posterior Superior Alveolar Block.

The posterior superior alveolar (PSA) block injection is one of many techniques used to provide profound anesthesia for invasive dental procedures. This technique has a high success rate but is not without complication risks. The purpose of this study was to determine if pulpal anesthesia of the maxillary second molar could be achieved using a reduced needle depth of 10mm or 5mm compared to the traditional needle depth of 16mm.

Effective and Ineffective Clinical Teaching in Dental Hygiene Education: A Qualitative Study.

Clinical instructors play a significant role in student learning in dental hygiene education, but more information is needed on which instructor characteristics best promote student development. The aim of this study was to identify clinical dental hygiene instructor traits that are effective and ineffective for student learning as defined by dental hygiene students and instructors. A qualitative study using grounded theory and critical incident technique was conducted to investigate junior students', senior students', and instructors' perceptions in one U.

Reduced Depth Technique with the Posterior Superior Alveolar Block.

The posterior superior alveolar (PSA) block is one of many techniques used to provide profound anesthesia for invasive dental procedures. This technique has a long history, with a high success rate, but is not without complication risks. The purpose of this study was to determine if pulpal anesthesia of the maxillary second molar could be achieved using a posterior superior alveolar block with a reduced depth of penetration of 10 mm compared to the current suggested depth of 16 mm.
