Research summary
The aim of this study is to compare 3D intra-oral scanner images (3Shape Trios Scanner) of the teeth and gums with standard clinical assessments to assess gum health. In this study 3D intra-oral images will be captured by a dental clinician and graded for gum health according to the modified gingival index (MGI). These grades will be compared against gold standard clinically derived MGI assessments, within the same subject.
This study is a blind (blind to the clinicians assessing the 3D image scans) single visit study in healthy participants. Sufficient participants aged over 18 years will be recruited to the study to ensure approximately 210 sites within the mouth are scored in total across all participants assessed. The scorable sites will be recorded by the MGI score (0, 1, 2, 3 and 4). The sites for assessment will be the buccal and lingual margin of each scorable tooth with one score provided for the full buccal margin and one MGI score for the full lingual/palatal margin. It is anticipated that up to 100 participants may be recruited.This study also aims to evaluate the sensitivity of the 3D scanner to differentiate between healthy gingivae and gingivitis, as measured by indirect assessment of images (using MGI). Gingival health assessed by gingival colour and texture will be compared between clinical assessment and assessment of captured scans.
