BACKGROUND: The oral examination is an essential part of the multidisciplinary medical care in elderly @entity1 . @entity3137 and normal variations of oral anatomy (OMLs) are very common in this @entity1 , but few studies have examined the frequency and prevalence of these conditions worldwide and less in Chile. The aim of this research was to evaluate the frequency of OMLs in a Chilean elderly population. MATERIAL AND METHODS: It was conducted a retrospective study (Talca, Chile). Two hundred seventy-seven OMLs were classified in groups and anatomical sites. In order to contextualize our numbers, we made a systematic review using Publish or Perish software, Google Scholar and InteractiVenn. RESULTS: The most prevalent OMLs groups were soft tissue @entity5 , epithelial pathology, @entity158 and @entity4094 , and @entity66 . The most frequent OMLs included @entity146 @entity81 (30 @entity1 , 10.8%), @entity2695 (20, 7.2%), @entity8511 (20 cases, 7.2%), @entity8619 (12, 4.3%) and epulis fissuratum (12, 4.3%). In the systematic review, 75 OMLs were relevant and the more studied pathologies were traumatic ulcerations (11 of 15 articles), @entity8619 (10/15), @entity146 @entity81 , @entity2118 , and recurrent @entity7809 (9/10, respectively). Considering all included articles, most frequent OMLs in elderly @entity1 included denture-related @entity3136 (13.3%), @entity146 @entity81 (8.7%) and @entity8145 (6.3%). CONCLUSIONS: The results reflect the frequency of OMLs diagnosed in a specialized service in south of Chile and many countries around the world. These numbers will allow the establishment of preventive politics and adequacy of the clinical services. Key words: @entity3137 , elderly @entity1 , Chilean population, frequency, systematic review.

XXXX in a Chilean elderly population: A retrospective study with a systematic review from thirteen countries.
