Assessment of the impact of tongue size in patients with bimaxillary protrusion.

Background: Tongue size, posture and pressure are considered to have significant influences on the positioning of dentoalveolar structures. Based on the equilibrium theory, forward resting posture of the tongue with light force and long duration could have both a horizontal and vertical effect on teeth. Bimaxillary proclination, a malocclusion trait often seen in African descents with multifactorial etiological factors, could well be related to tongue dimensions.

Impact of oral conditions on the quality of life of secondary schoolchildren in Nigeria.

Purpose: Oral health problems have been increasingly recognized as important factors causing a negative impact on daily performance and quality of life. The purpose of this study was to assess the impact of tooth extraction with no replacement, untreated fractured anterior teeth, malocclusion, dental restorations, and orthodontic braces on the quality of life in Nigerian schoolchildren.

Methods: A total of 197 9- to 17-year-old schoolchildren completed the Oral Health Impact Profile (OHIP) index/questionnaire.
