Oral diseases: a 14-year experience of a Chilean institution with a systematic review from eight countries

Abstract

BackgroundRetrospective studies to assess the distribution of oral diseases (ODs) are helpful in estimating the prevalence of oral diagnoses in the population, and thus help in preventive and curative services. Prevalence and frequency data for ODs are available from many countries, but information from Chile is scarce.Material and MethodsThis study investigated the frequency of ODs in a Chilean population. For this, we included all patients treated at the University of Talca (UTALCA, Chile) between 2001 and 2014. Patient characteristics were retrieved from medical files. To contextualize our results, we conducted a systematic review (SystRev) using Publish or Perish software (PoP), Google Scholar and MEDLINE/PubMed.ResultsOne hundred sixty-six ODs were diagnosed, and the most prevalent groups were soft tissue tumours, epithelial pathology and salivary gland pathology. Individually, irritation fibroma, oral lichen planus (OLP) and mucocele were the most common diagnoses. ODs frequently affected unspecified parts of the mouth (including cheek, vestibule and retromolar area), gum, lips, tongue and palate. In the SystRev, the more studied diagnoses were leukoplakia, OLP and recurrent aphthous stomatitis; prevalent lesions included Fordyce’s spots, recurrent aphthous stomatitis and fissured tongue. Chilean patients and SistRev shared almost all ODs.ConclusionsThe results reflect ODs diagnosed in a specialized service of oral pathology and medicine in Chile and will allow the establishment of preventive/curative policies, adequate health services and dentistry curriculum. Key words:Stomatognathic diseases, mouth diseases, oral mucosal lesions, epidemiology, Chilean population, retrospective cohort study.

The spectrum and frequency of histopathological diagnosis of oral diseases in Oslo: Implications to oral pathology syllabus

“…Oral lichen planus showed a female predominance in the present study and the result accords well with the studies by Dovigi et al and Rivera et al 16,17 The studies from Australia, Chile and USA did not mention lateral periodontal cyst. [15][16][17] This could be due to a relatively low prevalence of this cyst. In a Turkish study, lateral periodontal cyst constituted 0.12% of odontogenic and non-odontogenic cysts.…”

Biting Fibroma of the Lower Lip: A Case Report and Literature Review on an Irritation Fibroma Occurring at the Traumatic Site of a Tooth Bite

“…Several terms have been used to describe a biting fibroma (Table 1) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Indeed, the lesion is commonly referred to as either an irritation fibroma or a traumatic fibroma [1,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

However, similar to the patient in this report, when the lesion is the sequelae of self-biting (whether intended or nonintentional), it is reasonable to include the mechanism of pathogenesis in the diagnosis: biting fibroma [8,13].…”

“…The incidence of biting fibroma ranges from 1% (12 lesions per 1000 patients) to 15% (193 lesions per 1290 patients) [4,8]. Information from several studies on oral lesions published between 1986 and 2019 is summarized in Table 2 [1,2,5,6,[9][10][11]16,19,20]. In one study, biting fibroma was the most observed oral lesion [20].…”
