Total Net D12FS Caries Increment (Total of Non-cavitated Lesions (D1), Cavitated Lesions (D2) and Sound Surfaces (S))
Periodo de tiempo: (V1) to the 13 month follow-up visit
|
Study duration was too short to have progression from D2 (cavitated lesions) to D3 (cavitated lesions that involved dentin). D2 and D3 were treated equivalently for analysis. This measure is computed as the sum of weighted counts of transitions in tooth surface status (root and coronal surfaces combined) from randomization to the 13-month follow-up visit. Disease progression had a positive weight (e.g., S-to-D1 (sound to non-cavitated lesion) or D1-to-D2 (non-cavitated to cavitated lesion) = 1, S-to-D2 (sound to cavitated lesion)= 2). Reversal had a negative weight (e.g., D1-to-S = -1). No change, transitions to or from missing or unscorable, and impossible transitions had 0 weight. Incident fillings and crowns were treated the same as incident D2 lesions for purposes of scoring. More details of the transition weights may be found at Vollmer WM et al. (2010).

Medida Descripción |
Periodo de tiempo |
---|---|---|
Cumulative Net D12FS Caries Increment
Periodo de tiempo: Visit 1, 7-month follow-up, 13-month follow-up
|
This measure was computed similar to the total net D12FS increment, but separately scored and combined transitions from the baseline to 7-month visits and from the 7- to 13-month visits, rather than simply looking at the baseline to 13-month visits.
|
Visit 1, 7-month follow-up, 13-month follow-up
|
Total Crude D12FS Caries Increment
Periodo de tiempo: V1-13-month follow-up
|
Computed analogous to the total net D12FS caries increment, but ignoring reversals (essentially assigned them zero weight).
Computed only using baseline to 13-month visit data.
|
V1-13-month follow-up
|
Cumulative Crude D12FS Caries Increment
Periodo de tiempo: Visit 1, 7-month follow-up, 13-month follow-up
|
This is computed analogous to the cumulative net D12FS increment, but ignoring reversals by assigning them weights of zero.

Visit 1, 7-month follow-up, 13-month follow-up
