Abstract
Introduction: Supernumerary teeth are a clinical dilemma and are difficult to identify and
classify. Hence the main aim of this study was to assess the prevalence of supernumeraries in
the orthodontic patients of Margalla Institute of Health Sciences, Rawalpindi, Pakistan and
present a numbering system for supernumerary teeth which gives specific information in
regards to location, morphology and number to assist in easy communication in
interdisciplinary dental care.
Material and Methods: Total of 550 patients were assessed for this study. Clinical
examination, Intra-oral photographs, dental casts and radiographs of patients were used for
assessment of presence or absence of supernumeraries and their types. To assess the effect of
gender and upper / lower jaws on prevalence of supernumeraries, Chi Square test was
employed. These records were also used to explain the new proposed, „MRN‟ supernumerary
notation.
Results: Out of 550 patients, 16 had supernumeraries. Prevalence was calculated to be 2.9%.
Their prevalence was predominant in males. Conical supernumerary was the most prevailing
type followed by supplemental. The prevalence of supernumeraries was higher in maxilla.
New proposed, MRN supernumerary notation is explained with examples.
Conclusions: As no accord was seen on the nomenclature of supernumerary teeth, this article
not only presents the prevalence of supernumerary teeth but an effective supernumerary
notation which gives specific information regarding location, type and number of
supernumerary that can be applied to all the three-leading dental nomenclatures in both
manual and computed forms.
