Supernumerary teeth occur in both syndromic and nonsyndromic patients, and dental professionals are likely to encounter such teeth in their professional careers. There are three main numbering systems used to identify teeth today: the Universal/ National, the Palmer/Zsigmondy notation, and the Federation Dentaire Internationale (FDI) numbering systems. However, a review of the literature suggests that none of these three consistently addresses the identiication of supernumerary teeth. Being able to communicate the location of supernumerary teeth is important for dental professionals, especially in interdisciplinary situations. This article proposes a guideline to locate and identify supernumerary teeth in two and three dimensions, which may reduce treatment errors and improve communication among health care providers and third-party administrators.Dr.

Noonan syndrome (NS) is a relatively common condition characterized by chest deformation, congenital heart disease, short stature and distinctive facial features. Due to its genetic heterogeneity NS patients exhibit a range of clinical signs. Severe gingivitis and supernumerary teeth are rarely seen in connection with NS. In addition, there has not been a report on NS patients with atypical bilateral enlargement of the mental foramens and inferior-alveolar canals. This case report describes a NS patient who has undergone growth hormone (GH) therapy and is presenting with classical and rare NS phenotypes.

ObjectiveTo determine Korean facial profile preferences based on lip position as assessed by Hispanic-Americans of varying western adaptation levels and to determine whether the age and sex of the rater had any influence.MethodsFor this study, 132 Hispanic-Americans and 68 Caucasians of varying age, sex and western adaptation levels volunteered to rate their preference of Korean male and female facial silhouettes having lips ranging from retruding to protruding. The Hispanic-Americans were also asked to complete a Bidimensional Acculturation Scale questionnaire to determine their western adaptation status: low-acculturated Hispanics (LAH; lesser western-adapted Hispanic participants) or high-acculturated Hispanics (HAH; higher western-adapted Hispanic participants).ResultsThe LAHs preferred significantly more retruded lip positions (p < 0.05) while HAHs showed some similarities with Caucasian participants in the results for the Korean male profile, even though HAHs preferred more retruded lip positions for the Korean female profile than Caucasians did (p < 0.05). The age and sex of raters did not influence the preference of facial profiles (p > 0.05).ConclusionsThe results of this study suggest that Hispanic-Americans prefer a flatter Korean lip profile. It would be prudent for orthodontists to offer patients the option of altering lip profile through orthodontic and/or orthognathic surgery treatments.
