  • Title: Non-syndromic multiple supernumerary teeth: meta-analysis.
    Author: Alvira-González J, Gay-Escoda C.
    Journal: J Oral Pathol Med; 2012 May; 41(5):361-6. PubMed ID: 22092693.
    Abstract:
    BACKGROUND: Non-syndromic multiple supernumerary teeth (NSMST) is a condition with a very low prevalence and which is opportunely described in the literature by case reports or group of cases. This represents a problem when it comes to describing and discussing the characteristics of this disorder. MATERIALS AND METHODS: A search was conducted in PubMed, Web of Knowledge, Science Direct, and Scopus databases to locate and identify cases and series of cases about articles on multiple supernumerary teeth not associated with syndromes that have been reported so far. The following data were recorded: age, gender, total number of supernumerary teeth, number of teeth in both the maxilla and mandible, respectively, and number of teeth in each dental series (incisor, canine-premolar, and molar). Bilaterality in dental series and its localization in either maxilla or mandible were also determined. RESULTS: A total of 46 cases including patients of both genders with a mean age of 19 years (SD = 6.826) and a ratio of 2.14:1 were identified. A total of 393 supernumeraries were reported; 43.26% (n = 170) were located in the maxilla and 56.74% (n = 223) in the mandible. No significant differences were found between genders with respect to the total number, involvement of the dental series, or distribution of supernumerary teeth in each of the arches. CONCLUSION: Although NSMST is a condition that has a higher incidence in the male gender, no differences have been found as to their number and localization in both genders. Bilaterality seems to be a common characteristic of this disorder.
