Quantification of gingival contour and volume from digital impressions as a novel method for assessing gingival health.

Objective: To evaluate the novel assessment of gingival contour volume measurement from digital impressions compared with traditional clinical indices (Modified Gingival Index and Bleeding Index) and oral microflora following a dental prophylaxis.

Methods: Following baseline examinations and full mouth digital impression using the LAVA™ Oral Chairside Scanner (COS), subjects had one maxillary quadrant and the contra-lateral mandibular quadrant randomly allocated to receive a complete dental prophylaxis. Subjects then brushed twice daily at home using a standard toothpaste.
