[10]. Despite their simplicity as general assessment tools for oral health, these indices have some limitations when measuring plaque levels. Limitations to this assessment include variations in the numbers of teeth assessed, the use of binary scores (0 for absence, 1 for presence) to indicate ...

This study included all episodes of adult single tooth DGA in all RCHT sites during 2014, except for mandibular third molar and impacted teeth. Each case was tested against the DGA case selection criteria empirically devised for this study. In 2014, 106 episodes of adult single tooth DGA were...
