abstract = "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. Papilla height (PH) and area (PA) and tooth crown area (TCA) were estimated on all photographs; the {"}best-match-to-baseline{"} photograph from those taken at 3 and 6 months was chosen by 6 evaluators.RESULTS: Within the first 10° of deviation from the baseline shooting angle, measurements on the 2D {"}scan pictures{"} distorted ≤0.5 mm for PH and ≤10{\%} for PA and TCA. Compared to baseline, only 6 out of 100 photographs presented ≥0.5 mm difference in PH, none of the TCA measurements showed distortion ≥10{\%}, and only in 4 instances a ≥10{\%} distortion of the PA was observed. Poor to moderate inter- and intra-rater agreement in choosing the {"}best-match-to-baseline{"} photograph was found, but photographs with clinically relevant changes were only seldomly chosen.CONCLUSIONS: Deviations in the shooting angle ≤10° from the baseline shot cause clinically negligible distortions in linear and planimetric measurements. Highly comparable intraoral photographs of the anterior maxillary teeth can be captured {"}free-hand{"} in slightly varying perspective, and then selecting the {"}best-match-to-baseline{"}.",
