Reproducibility of intraoral photography for pink and white tissue assessment - Is it worth the hassle?

Purpose: To assess the effect of the shooting angle variation on linear and planimetric measurements of the pink and white tissues on intraoral photographs.

Methods: From intraoral three-dimensional (3D) scans of the anterior region in 10 patients, ninety-nine two-dimensional (2D) "scan pictures" each were generated with different shooting angles, each varying in 5° horizontal and vertical increments. Eleven intraoral photographs of each patient and tooth site were taken free-hand: one shot at baseline and 5 shots after 3 and 6 months at slightly varying shooting angles.
