Layperson's preference of the transverse occlusal plane in asymmetric facial model.

Objective: Facial asymmetries are common, especially deviated nose and chin. The clinician must consider these variables when establishing the smile, placement and angulation of the occlusal plane. The purpose of this article is to determine if nose and chin deviations affect the perception of laypeople towards different angulations of the occlusal plane cant.

Comparison of a non-destructive technique using three-dimensional imaging and histoanatomical chemical dissolution for dental morphology analysis.

Aim: The present work aims to compare a digital dental histoanatomical analysis method with chemical enamel dissolution for the study of dental morphology.

Material And Methods: Extracted maxillary anterior teeth were scanned under microcomputed tomography (μCT) (μCT 40; Scanco Medical), segmented, and reconstructed three-dimensionally (Amira, version 5.5.
