A clinical epidemiologic analysis of a sample of 73 supernumerary premolars. J Am Dent Assoc. 2010 Dec;141(12):1435-41. doi: 10.14219/jada.archive.2010.0105.0002-817710.14219/jada.archive.2010.0105https://hdl.handle.net/20.500.14352/129332Background: The authors conducted a retrospective study to determine the prevalence of supernumerary premolars in sample of patients from Madrid, as well as the possible complications associated with the presence of such supernumerary premolars. Methods: The study included a data assessment of all patients seeking dental care at a hospital's department of oral surgery across four years. The authors studied data from patients who had supernumerary premolars. Results: The authors identified supernumerary premolars in the records of 43 patients (0.32 percent) of the total population studied. These patients had 73 hyperdontic premolars (65 mandibular premolars [89 percent] and eight maxillary premolars [11 percent]). Conclusions: Supernumerary premolars usually are diagnosed as a coincidental radiographic finding without an associated pathology. However, the authors found a higher percentage of comorbidity than they initially expected. Clinical implications: Mechanical or obstructive pathology was associated with 2.7 percent of the premolars, and enlargement of the follicular sac of more than 3 millimeters was present in 26.0 percent of the sample.engjournal article1943-4723https://doi.org/10.14219/jada.archive.2010.010521119127https://www-sciencedirect-com.bucm.idm.oclc.org/journal/the-journal-of-the-american-dental-association/vol/141/issue/12https://pubmed.ncbi.nlm.nih.gov/21119127/restricted access616.314-007(460.27)Supernumerary premolarsPrevalenceMorphologyAssociated pathologyImpactedOdontología (Odontología)Cirugía bucofacial3201 Ciencias Clínicas3213 Cirugía
