Reliability Of Colour And Hardness Clinical Examinations In Detecting Dentine Caries Severity: A Systematic Review And Meta-Analysis., Larry Hon, Ahmed Mohamed, Edward Lynch

Dental Medicine Faculty Publications

Dental caries is the most common human infectious disease and is caused by microorganisms producing acids, resulting in changes in dental tissue hardness and colour. However, the accuracy and reliability of dentine colour and hardness as indicators for carious lesion severity has never been assessed in a systematic review. By applying strict criteria, only seven papers (five randomized control trials and two diagnostic studies) were considered for full text qualitative and quantitative assessment. Only three studies produced high quality evidence and only four articles were considered for meta-analysis, as these provided log10 colony forming units (CFU) data from caries biopsies …

Utilization Of Rectangular Collimation In Dental And Dental Hygiene Programs, Elizabeth Ann Wagner

Dental Hygiene ETDs

Rectangular collimation has proven to reduce the radiation dose to the patient as well as increase image quality. Studies have been conducted in the past to determine whether utilization of rectangular collimation results in a greater retake rate, however, there is a lack of data regarding the amount of rectangular collimation devices that are currently in use. The purpose of this study was to determine to what extent, if any, rectangular collimators are being utilized in dental and dental hygiene programs. A survey was created and sent via email to the program directors of Accredited dental and dental hygiene programs. …
