The importance of the ANSI ADA Standard for digital intraoral radiographic systems-a pragmatic approach to quality assurance.

The need for quality assurance (QA) for digital dental radiography has existed since the introduction of digital imaging; however, the methods and phantoms required to achieve it were not available. This resulted in a chaotic approach to address QA based largely upon subjective analysis of image quality. The American National Standards Institute (ANSI)/American Dental Association (ADA) Quality Assurance Standard 1094 for Digital Intraoral Radiographic Systems (DIRS) presents a paradigm shift to a scientific and objective method of QA rather than one based on subjective assessments.

Quality assurance: acceptance testing for digital dental intraoral sensors.

Objective: The aim of this study was to demonstrate the need for acceptance testing with digital dental intraoral sensors (DIOS) as the first step of a comprehensive quality assurance (QA) program.

Study Design: Five commercially available DIOS were tested by using a QA test phantom, satisfying the requirements for intraoral QA testing as specified in American Dental Association Technical Report No. 1094 (TR 1094).

Tongue piercing: case report and ethical overview.

A case of infection following piercing of the tongue is presented. A dentist allegedly provided local anesthesia to the tongue prior to piercing. To avoid criticism from the first dentist, the patient saw a different dentist to treat the infection.
