Abstract

The role of third molars in the oral cavity has been extensively studied over the years. Literature includes numerous diagnostic and treatment alternatives regarding the third molars. However, an issue that has not been discussed at the same level is their involvement in orthodontic therapy. The aim of this study is to present a review of the contemporary literature regarding the most broadly discussed aspects of the multifactorial role of third molars in orthodontics and which are of general dental interest too.

Keywords: Crowding; Extraction; Eruption; Third molar; Orthodontics; Impaction

Core tip: There are multiple factors associated with the eruption or impaction of third molars. According to the existing literature, orthodontic extraction treatment is not directly associated with the eruption of third molars, but might have a positive effect on their position and angulation. There is currently no reliable research evidence supporting the prophylactic removal of non-pathological impacted third molars for the prevention or relief of mandibular incisor crowding.
