The article reviews the heritability of dental arches and occlusal parameters, finding high heritability for dental arch dimensions and moderate to low heritability for occlusal parameters, though evidence certainty is low.

Keywords: dental arch, dental occlusion, genetics, heritability, malocclusion, siblings, twins

Educational Objectives

Educational Aim:
To inform readers about the genetic factors influencing dentoalveolar characteristics, specifically dental arch dimensions and occlusal parameters. It aims to provide an evidence-based understanding of the heritability of these traits, highlighting the variability in heritability estimates and the overall strength of the available evidence.

Educational Outcomes:
Upon completion of this module practitioners should have a clear understanding of:

  1. Heritability in Dentistry
  2. Critical Evaluation of Evidence
  3. Awareness of Research Variability
