Prevalence and presentation of hyperdontia in a non-syndromic, mixed Nigerian population.

Background: Although there have been studies on the prevalence and pattern of hyperdontia in sub-Saharan African subjects with similar cultural backgrounds, based on our search, none have been able to consider these epidemiological parameters in a multiethnic black population, which is expected to add substantial knowledge to what is available.

Material And Methods: This is a retrospective study on the panoramic radiographs of subjects who presented at two dental centres in Abuja, Nigeria between June 2013 and June 2018. Radiographic interpretations were carried out by three independent observers, trained on computer assisted radiographic image interpretation.

Mental Foramen Size, Position and Symmetry in a Multi-Ethnic, Urban Black Population: Radiographic Evidence.

Objectives: To determine the approximate location, shape and dimensions of the mental foramen in African subjects using panoramic radiographs.

Material And Methods: This study analysed 320 orthopantomograms of subjects from two centres. The analysis was done using the radiographic software tools (SIDEXIS, Bensheim, Germany) which allowed for determination of the position, shape and dimensions of the foramen.
