Intraoral Imaging: Basic Principles, Techniques and Error Correction

A History and Update of Fluoride Dentifrices

Proper patient care includes a complete oral examination and obtaining diagnostic intraoral and/or extraoral radiographs when indicated in accordance with radiographic selection criteria.1 Radiographic images are essential for proper patient diagnosis, treatment and re-evaluation. Radiographic images are especially useful in the diagnosis and treatment of dental caries, periodontal bone loss, periapical pathosis and for making other observations relevant to patient treatment such as changes in the bone pattern, anatomical variations in tooth anatomy and surrounding anatomical structures. It is imperative that dental professionals are well versed in technique and competent in taking intraoral radiographs to ensure diagnostically acceptable images are produced, while keeping the amount of radiation exposure to patients at a minimum.
