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.

European survey on criteria of aesthetics for periodontal evaluation: The ESCAPE study.

Objective: The ESCAPE multicentre survey was designed to (a) compare the agreement of three relevant aesthetic scoring systems among different centres, and (b) evaluate the reproducibility of each question of the questionnaires.

Materials And Methods: EFP centres (n = 14) were involved in an e-survey. Forty-two participants (28 teachers, 14 postgraduate students) were asked to score the one-year aesthetic outcomes of photographs using the Before-After Scoring System (BASS), the Pink Esthetic Score (PES) and the Root coverage Esthetic Score (RES).
