Image distortion of intra-oral photographs: The root coverage model.

Aim: Clinical photographs have been advocated in studies dealing with the quantity of root coverage. Changes in different angles of the camera when taking a photograph may lead to parallax errors resulting in inaccurate measurements. The aim of this study was to explore the distortion of the photographs according to the shooting angle.

The relationship between dental implant papilla and dental implant mucosa around single-tooth implant in the esthetic area: A retrospective study.

Objective: The aim of the present study was (a) to evaluate the relationship between dental implant mucosa and dental implant papilla levels; and (b) to identify the clinical parameters associated with peri-implant soft tissue stability over time.

Materials And Methods: This is a retrospective study on a cohort of patients seeking a single-tooth implant therapy in a private practice in the Paris area. Two independent examiners analyzed photographs and radiographs taken the day of definitive crown load (baseline) and the last follow-up visit (at least 12 months later) in order to measure four peri-implant soft and hard tissue parameters.
