Accuracy and reliability of 2-dimensional photography versus 3-dimensional soft tissue imaging.

Purpose: This study was conducted to objectively and subjectively compare the accuracy and reliability of 2-dimensional (2D) photography and 3-dimensional (3D) soft tissue imaging.

Materials And Methods: Facial images of 50 volunteers (25 males, 25 females) were captured with a Nikon D800 2D camera (Nikon Corporation, Tokyo, Japan), 3D stereophotogrammetry (SPG), and laser scanning (LS). All subjects were imaged in a relaxed, closed-mouth position with a normal smile.

CBCT in orthodontics: a systematic review on justification of CBCT in a paediatric population prior to orthodontic treatment.

Background: Taking into account radiation doses, safety, and protection, we highlighted the features in which cone-beam computed tomography (CBCT) can offer an advantage compared to the conventional two-dimensional imaging in paediatric dentistry before orthodontic treatment.

Objective: The aim of this article was to conduct a systematic review to assess the diagnostic efficacy of CBCT in the paediatric population at a pre-orthodontic phase.

Search Methods: MEDLINE via PubMed was searched to identify all peer-reviewed articles potentially relevant to the review until 1 July 2018.
