ABSTRACT
BACKGROUND: Supernumerary teeth are those that exceed the usual dental formula. There are different classifications depending on their anatomical location, shape and number. The objective of this study was to determine the prevalence of impacted and supernumerary teeth in a sample of panoramic radiographs from three Latin American countries. MATERIAL AND METHODS: A retrospective and cross-sectional study with a quantitative approach, in which the radiographic observation and analysis of 2000 panoramic radiographs, provided by different radiological centers in Peru, Colombia and Bolivia were performed. An examiner, specialized in Stomatology and Oral Surgery, carried out the radiographic analysis to detect the presence of impacted teeth and supernumeraries teeth. All the images were evaluated in a dark room in digital format. The SPSS version 23 package was used for statistical analysis. The Chi-square test was used to determine the association of age, sex, and nationality with the presence of impacted or supernumerary teeth. The level of significance was p< 0.05. RESULTS: The prevalence of impacted teeth was 1.7%, with the upper left canine being the most frequent (58.85%). The prevalence of supernumeraries was 3.15% (76 cases), the most frequent being the mesiodens with 1.7% (34), and Peru showing the highest prevalence of mesiodens. No association was found regarding sex. CONCLUSIONS: The prevalence of impacted teeth evaluated in three recognized radiologic centers from three Latin American countries was low, with the upper left canine being the most frequently impacted tooth. Likewise, the prevalence for supernumerary teeth was also low, with mesiodens having the highest prevalence. Key words:Supernumerary tooth, impacted tooth, panoramic radiograph.
ABSTRACT
La fascitis necrotizante (FN) es una infección poco común. Las primeras manifestaciones clínicas incluyen fiebre, dolor intenso, edema y enrojecimiento en el sitio de la herida. Esta patología se caracteriza por la evolución fulminante y la alta tasa de mortalidad que representa. El propósito del presente trabajo es describir las características de la fascitis necrotizante de origen odontogénico mediante la presentación de un caso clìnico y una revisión de la literatura y destacar las graves consecuencias que una infección dental podría desencadenar. Se resalta el enfoque multidisciplinario en estos casos y la interacción constante entre las diferentes especialidades médico-odontológicas para garantizar una gestión adecuada de cada caso. (AU)

This pathology is characterized by the fulminating evolution and the high mortality rate it represents. The purpose of this work is to describe the characteristics of Necrotizing Fasciitis of Odontogenic Origin by presenting a clinical case and a review of the literature and highlight the serious consequences that a dental infection could trigger. The multidisciplinary approach is emphasized in these cases and the constant interaction between the different medical-odontological specialties to guarantee an adequate management of each case.
