Prevalence of Oral Lesions Diagnosed at a Pathology Institute: A Four-year Analysis

Abstract Objective: To identify the most prevalent oral lesions based on reports from a pathology institute's reports and associations between malignant and oral potentially malignant disorders with patient's demographic variables and the anatomical location. Material and Methods: All 1,298 histopathological reports of oral lesions recorded in the database were reviewed. Demographic variables, anatomical location of the lesion, histopathological diagnosis of the lesions, and their biological behavior were analyzed. Results: Regarding the biological behavior of the identified lesions, benign lesions were predominant (70%), followed by lesions of undetermined behavior (14.3%), malignant lesions (14.2%), absence of histological alteration (1.2%), and finally, oral potentially malignant disorders (0.5%). The anatomical locations of the most prevalent oral lesions potentially malignant disorders and malignant were in the following structures of the oral cavity: gums, buccal mucosa, floor of the mouth and hard palate (p=49.2%), and tongue (p=48.7%). Conclusion: The probability of malignant and premalignant lesions was higher among males (PR= 4.21; 95% CI 2.08-6.22), the increase in age (PR = 1.06; 95% CI 1.05-1.08), and in the tongue region (PR = 5.48; 95% CI 1.67; 17.92). Identification of malignant and potentially malignant oral conditions is higher in older men and in tongue specimens.

Síndrome de Laugier-Hunziker, reporte de un caso y revisión de la literatura / Laugier-Hunziker syndrome, case report and literature review

El síndrome de Laugier-Hunziker (SLH) es un trastorno de hiperpigmentación macular benigno adquirido que se caracteriza por la presencia de máculas hiperpigmentadas policrómicas, de superficie plana, con morfología lenticular oval, de márgenes definidos; parte importante de éste es el desarrollo de melanoniquia longitudinal. Su principal diagnóstico diferencial es el síndrome de Peutz-Jeghers, ya que este último tiende a desarrollar neoplasias malignas en el tracto digestivo. Es importante que el estomatólogo conozca el SLH, con la finalidad de poder diagnosticarlo y diferenciarlo de otras entidades, particularmente de aquellas de carácter maligno (AU)

Laugier-Hunziker syndrome (LHS) is an acquired benign macular hyperpigmentation disorder, characterized by the presence of polychromic hyperpigmented macules, with a smooth surface, with oval lenticular morphology, with defined margins; An important part of this is the development of longitudinal melanonychia. Its main differential diagnosis is Peutz-Jeghers syndrome, since it tends to develop malignant neoplasms in the digestive tract. It is important that the Stomatologist knows the LHS, in order to be able to diagnose it and differentiate it from other entities, even those of a malignant nature (AU)

Análise da imunoexpressão de BAX e MMP-9 no líquen plano oral / Analysis of BAX and MMP-9 immunoexpression in oral lichen planus

Introdução: O líquen plano oral é uma doença crônica imunologicamente mediada relativamente comum, que acomete a mucosa oral. Clinicamente, o LPO é classificado em seis padrões bem identificados: placa, reticular, bolhoso, atrófico, papular e erosivo.Sendo os mais comuns oos tipos reticulares e erosivos. A ativação dos linfócitos TCD4+ no LPO, pode induzir os ceratinócitos ao processo de apoptose através da respostaimunológica citotóxica. A proteína Bax desempenha uma função relevante para o processo apoptótico. Deste modo, a presente pesquisa consistiu em um estudo transversal retrospectivo, descritivo, quantitativo e comparativo. Objetivo: Avaliar a expressão imuno-histoquímica das proteínas MMP9 e Bax no LPO. Método: Foram utilizados 43 casos de LPO para análise da imunoexpressão de Bax e MMP-9. Os resultados foram analisados através dos testes estatísticos apropriados e serão considerados significativos, valores onde p<0,05. Resultado: A imunoexpressão de MMP9 foi significativamente maior nos ceratinócitos e quando analisados os subtipos de líquen plano oral, não foram observados diferenças estatísticas entre os tipos reticulares e erosivos para as proteínas analisadas. Conclusões: Com essas observações, infere-se que a alteração na expressão das proteínas estudadas sugere um distúrbio nos mecanismos apoptóticos, os quais estão associados às lesões de LPO, e podemos concluir também que as imunoexpressões dessas proteínas não apresentaram diferença, quando relacionada ao tipo clínico reticular ou erosivo. Com esse resultado pode-se contribuir para um maior entendimento sobre os possíveis mecanismos celulares envolvidos na etiopatogenia dessa lesão (AU).

Background: Oral lichen planus is a relatively common immune-mediated chronic disease that affects the oral mucosa. Clinically, OLP is classified into six well-identified patterns: plaque, reticular, bullous, atrophic, papular, and erosive. The most common being the reticular and erosive types. The activation of TCD4+ lymphocytes in the OLP can induce keratinocytes to the process of apoptosis through the cytotoxic immune response. Thus, the present research consisted of a retrospective, descriptive, quantitative and comparative crosssectional study. Objective: to evaluate the immunohistochemical expression of MMP-9 and Bax proteins in OLP. Methods: We used 20 cases of Inflammatory Fibrous Hyperplasia as control. The results were analyzed through the appropriate statistical tests and will be considered significant, values where p<0.05. Results: The immunoexpression of MMP-9 was significantly higher in keratinocytes and when the subtypes of oral lichen planus were analyzed, no statistical differences were observed between the reticular and erosive types for the proteins analyzed. Conclusions: With these observations, it is inferred that the alteration in the expression of the studied proteins suggests a disturbance in the proliferative and apoptotic mechanisms, which are associated with a pathological behavior of the oral mucosa, and consequently with a repercussion on the lesions of OLP, and we can also conclude that the immunoexpression of these proteins had no difference, when related to the reticular or erosive clinical type. This research aims to contribute to a greater understanding of the possible cellular mechanisms involved in the etiopathogenesis of this lesion, thus enabling the understanding of the clinical aspects of the pathology (AU).

Hemangioma capilar lobular: granuloma piógeno en lengua / Lobular capillary hemangioma: pyogenic granuloma of tongue

El granuloma piógeno es una lesión benigna, reactiva y multifactorial que resulta de le- siones repetitivas, microtraumatismos e irritación local en piel o mucosas y cambio hormonal. Cuando aparece en la cavidad oral tiene predilección por la encía vestibular, pero es importante que el odontólogo esté consciente y familiarizado con el hecho de que puede estar localizado en otras áreas anatómicas. Clínicamente se presenta como lesión hiperplásica altamente vascularizada, de tamaño generalmente no mayor a 2 cm, pediculada en la base o sésil y de lento crecimiento. Sin mostrar preferencia por edad o sexo, tiende a aparecer principalmente en encías, labios y mucosa oral, siendo muy pocos los casos reportados en el área lingual. Es por ello que, en este artículo, nos referimos a un caso de ubicación inusual, en conjunto con una revisión de la literatura (AU)

Pyogenic granuloma is a benign, reactive, and multifactorial lesion caused by repetitive injuries, microtrauma and local irritation on the skin or mucous membranes, and hormonal change. When it appears in the oral cavity, it has a predilection for the vestibular gingiva, but the dentist must be aware and familiar with the fact that it can be present in other anatomi- cal areas. Clinically, it is presented as a hyperplasic injury highly vascular-related, with a size generally no bigger than 2 cm, pedunculated in base or sessile, and slow in growth. Without showing any preference in age or gender, it tends to appear mainly on the gums, lips, and oral mucosae, with very few, reported cases in the lingual area. Therefore, in this study, we refer to a case of unusual localization with a literature review (AU)

Lesiones bucales, factores de riesgo de cáncer bucal y autopercepción de irritación mecánica crónica en una campaña de prevención en la Ciudad de Buenos Aires / Oral lesions, oral cancer risk factors and self-perception of chronic mechanical irritation in a prevention campaign in Buenos Aires City

Objetivos: i) Describir las características poblaciona- les, la frecuencia de patologías de mucosa bucal y de factores de riesgo asociados al cáncer bucal en una Campaña de Pre- vención y Diagnóstico Precoz de Cáncer Bucal (CPDPCB) en la Ciudad de Buenos Aires; ii) establecer concordancia entre diagnóstico clínico profesional de irritación mecánica crónica (IMC) y autopercepción de trauma. Materiales y métodos: Se realizó un estudio descrip- tivo retrospectivo, en el que se utilizaron encuestas de 640 pa- cientes que participaron en las CPDPCB del Servicio de Odon- tología del Hospital Alemán entre los años 2016, 2017 y 2018. Se describen las variables demográficas, clínicas y cognitivas, y se analizan empleando chi cuadrado para variables cualitativas y ANOVA para variables cuantitativas comparando los años de campaña. Se realizó un estudio de concordancia entre el diag- nóstico clínico profesional de IMC y el trauma autopercibido mediante test Kappa, sensibilidad y especificidad. Resultados: Los sujetos participantes fueron predomi- nantemente mayores de edad, con bajo consumo de tabaco y alcohol. El porcentaje de pacientes con desórdenes potencial- mente malignos y cáncer bucal fue de 17,2%. La cartelería del hospital y la radio fueron las principales vías de información a los pacientes. El trauma autopercibido no presentó concor- dancia con el diagnóstico clínico profesional de IMC, y mos- tró sensibilidad de 0,41 y especificidad de 0,72. Conclusiones: El nivel de participación de los grupos de mayor riesgo de CBCE en la CPDPCB es bajo, y el perfil epidemiológico de los participantes no coincide generalmente con el perfil de los pacientes con CBCE. La autopercepción de trauma no sería una herramienta confiable para el diagnóstico de IMC (AU)

Aims: i) To describe population characteristics, frequency of oral mucosa pathologies, and risk factors for oral squamous cell carcinoma (OSCC) in a Campaign for the Prevention and Early Diagnosis of Oral Cancer (CPEDOC), and ii) to establish concordance between professional clinical diagnosis of chronic mechanical irritation (CMI) and self-perception of trauma. Materials and methods: A retrospective descriptive study was performed using surveys of 640 patients who had participated in the CPEDOC conducted by the Dentistry Ser- vice at the Hospital Alemán during 2016, 2017 and 2018. De- mographic, clinical and cognitive variables were described and analyzed, using chi-square for qualitative variables and ANOVA for quantitative variables, to compare campaign years. Concordance was studied between the professional clinical diagnosis of CMI and self-perceived trauma using the Kappa test, sensitivity and specificity. Results: Participants were predominantly older, with low consumption of tobacco and alcohol. The percentage of patients with potentially malignant disorders and oral cancer was 17.2%. Hospital posters and radio broadcasting were the main channels of information to patients. Self-perceived trauma did not agree with the professional clinical diagnosis of CMI. Self-perceived trauma sensitivity and specificity were 0.41 and 0.72, respectively. Conclusions: The level of participation in the CPEDOC by the groups at higher risk of OSCC was low, and the epide- miological profile of the participants did not generally coincide with the profile of patients with OSCC. Self-perception of trau- ma does not seem to be a reliable tool for the diagnosis of CMI (AU)

Epidemiología y frecuencia de enfermedades de transmisión sexual y su repercusión en la mucosa bucal: una revisión narrativa / Epidemiology and frequency of sexually transmitted diseases and their impact on oral mucosa: a narrative review

El objetivo de la presente revisión fue analizar y compa- rar las publicaciones sobre la prevalencia de manifestaciones bucales de pacientes infectados por el Virus de la Inmuno- deficiencia Humana, Virus del Papiloma Humano y sífilis. Se seleccionaron los artículos más relevantes y se abordó la incidencia según sexo, edad, distribución geográfica y locali- zaciones anatómicas frecuentes. Se encontró que las lesiones orales más prevalentes producidas por el Virus de la Inmu- nodeficiencia Humana son la candidiasis oral, la leucoplasia vellosa y enfermedades periodontales, entre otras. La sífilis presentó una frecuencia de 7,5% de manifestaciones orales en la etapa primaria, 92,5% en la secundaria y rara vez lesio- nes en la terciaria. Las formas más prevalentes fueron parches mucosos, pápulas y úlceras. Las lesiones orales benignas rela- cionadas con el Virus del Papiloma Humano halladas fueron la verruga vulgar, el papiloma plano, el condiloma acuminado y la hiperplasia epitelial focal. La prevalencia de carcinomas orofaríngeos y orales fue del 33,6% y del 22,2% respectiva- mente. Se encontraron similitudes en el comportamiento se- xual y las vías de transmisión de las enfermedades analizadas, y se observó que son más prevalentes en adultos jóvenes de sexo masculino y en países en vías de desarrollo (AU)

The aim of this review was to analyze and compare pub- lications on the prevalence of oral manifestations in patients infected with Human Immunodeficiency Virus, Human Pap- illoma Virus and syphilis. The most reliable studies were se- lected, and incidence was evaluated according to gender, age, geographic location and frequent anatomic sites. It was found that the most prevalent Human Immunodeficiency Virus oral lesions were oral candidiasis, hairy leukoplakia and perio- dontal diseases, among others. Syphilis had a 7.5% preva- lence of oral manifestations in the primary stage, 92.5% in the secondary, and rarely lesions in the tertiary. The most prevalent forms were mucous patches, papules and ulcers. The benign oral lesions related to the Human Papilloma Vi- rus were verruca vulgaris, squamous papilloma, condyloma acuminatum and multifocal epithelial hyperplasia. The preva- lence of oropharyngeal and oral carcinomas were 33.6% and 22.2%, respectively. Similarities were found in sexual behavior and transmis- sion routes of the diseases analyzed, which were more preva- lent among young adult males, and in developing countries (AU)

El hábito de fumar y su relación con afecciones bucales en adolescentes / Smoking and its relationship with oral conditions in adolescents

RESUMEN Introducción: El hábito de fumar está asociado a una gran variedad de cambios perjudiciales en la cavidad bucal, pues altera su microambiente y lo predispone para que se presenten diversas afecciones. Objetivo: Determinar la posible relación del hábito de fumar con las afecciones bucales en adolescentes. Método: Se realizó un estudio observacional en adolescentes del Centro Mixto «Pepito Tey» de San Diego del Valle, Cifuentes, en el período comprendido entre septiembre de 2016 y octubre de 2018. La población de estudio, conformada por 208 adolescentes, se organizó en dos estratos: grupo estudio y grupo control. Se seleccionaron dos muestras probabilísticas por muestreo aleatorio simple (60 adolescentes en cada grupo). Resultados: Predominaron adolescentes de 12 años, fumadores leves, del sexo masculino, con inicio del hábito entre 14-15 años y práctica de este hábito de menos de 6 meses. Se asociaron al hábito de fumar: la caries dental, la enfermedad periodontal, las manchas dentales, las lesiones de la mucosa bucal y la halitosis. Conclusiones: Predominaron adolescentes fumadores masculinos de 12 años. La gran mayoría de los fumadores fueron clasificados como leves, con inicio del hábito entre los 14-15 años de edad, y con práctica desde hace menos de seis meses. Existió asociación significativa entre el hábito de fumar y las afecciones bucales (enfermedad periodontal, caries dental, mancha dental, halitosis y lesión de la mucosa bucal).

ABSTRACT Introduction: smoking is associated with a wide variety of harmful changes in the oral cavity, since it alters its microenvironment and predisposes it to the occurrence of various conditions. Objective: to determine the possible relationship between smoking and oral conditions in adolescents. Method: an observational study was carried out in adolescents from "Pepito Tey" Mixed Center, in San Diego del Valle, Cifuentes between September 2016 and October 2018. The study population, made up of 208 adolescents, was organized into two strata: study group and control ones. Two probabilistic samples were selected by simple random sampling (60 adolescents in each group). Results: 12-year-old male light smokers, who started smoking between 14 and 15 years of age and practiced this habit for less than 6 months, predominated. Dental caries, periodontal disease, dental stains, oral mucosal lesions and halitosis were associated with smoking. Conclusions: 12-year-old male adolescent smokers predominated. Most smokers were classified as light, started smoking between 14 and 15 years of age and practiced this habit for less than 6 months. There was a significant association between smoking and oral conditions (periodontal disease, dental caries, dental stains, halitosis and oral mucosal lesions).

Correlación del diagnóstico clínico e histopatológico de lesiones de la mucosa oral entre 2008-2015 en la Universidad de Costa Rica / Correlation of Clinical and Histopathological Diagnosis of Oral Mucosa Lesions at the University of Costa Rica Between 2008 and 2015

RESUMEN: El objetivo de este estudio es determinar la concordancia existente entre el diagnóstico clínico e histopatológico de las lesiones en la mucosa oral en la Facultad de Odontología de la Universidad de Costa Rica (UCR). Es un estudio retrospectivo de 261 informes de lesiones orales recuperados del archivo de biopsias de la Facultad de Odontología de la UCR de 2008 a 2015, fueron analizados 165 reportes que cumplian con los criterios de inclusión. La concordancia entre el diagnóstico clínico e histopatológico fue verificada mediante el test Kappa. Del total de los informes, 96 (36.8%) no contaban con alguna hipótesis diagnóstica. La concordancia con la primera hipótesis diagnóstica se presentó en 114 (69.1%) casos, el valor de kappa fue de 0.663 (concordancia sustancial). Las lesiones premalignas presentaron una concordancia excelente (kappa=0.902). La concordancia del grupo de lesiones proliferativas no neoplásicas fue moderada (kappa=0.504) y las condiciones dermatológicas y autoinmunes con una concordancia insignificante (0.157). La concordancia se produjo en la mayoría de los pacientes investigados con un valor correspondiente a un acuerdo sustancial, sin embargo, se debe mejorar el porcentaje de informes que no contaban con hipótesis clínica.

ABSTRACT: The objective of this study is to determine the existing concordance between the clinical and histopathological diagnosis of lesions in the oral mucosa at the Faculty of Dentistry of the University of Costa Rica (UCR). A retrospective study of 261 reports of oral lesions recovered from the biopsy archive of the UCR Faculty of Dentistry from 2008 to 2015. Of the total reports 165 were included in the analysis, 96 (36.8%) did not have any diagnostic hypotheses. The concordance between the clinical and histopathological diagnosis was verified by the Kappa test. Concordance with the first diagnostic hypothesis was presented in 114 (69.1%) cases, the value of kappa was 0.663 (substantial agreement) and 36.8% without clinical diagnosis only a description of the lesion. The premalignant lesions presented an excellent concordance (kappa=0.902). The concordance of the group of non-neoplastic proliferative lesions was moderate (kappa=0.504) and the dermatological and autoimmune conditions with negligible concordance (0.157). Concordance occurred in the majority of the patients investigated with a value corresponding to a substantial agreement, however, the percentage of reports that did not have a clinical hypothesis should be improved.

Púrpura trombocitopénica idiopática (pti): su diagnóstico a través de lesiones en cavidad oral / Purple Idiopathic Thrombocytopenic (Itp): diagnosis through lesions in the oral cavity

La PTI es una alteración hemorrágica de instalación súbdita, adquirida, que se manifiesta inicialmente con petequias, equimosis o hematomas en piel y mucosas, sangrado nasal y gingival, sin causa aparente. La mucosa bucal puede ser el sitio donde las lesiones se observen con frecuencia y por primera vez. Se reporta el caso de un paciente masculino de 28 años de edad, con manifestaciones clínicas de un cuadro purpúrico, se describen signos, síntomas, terapéutica y manejo estomatológico (AU)

PTI is a hemorrhagic alteration of sudden installation, acquired, which manifests initially with petechiae, esquimosis or bruises on skin and mucosae, nasal and gingival bleeding without apparent cause. Bucal mucosae can be the site where lesions are observed with frequency, and for the first time. The case of a male patient with 28 years of age with clinical manifestationsofpurpuric syndrome is reported, signs, symptoms, therapeutic and stomatological handling are described (AU)

Evaluación de lesiones orales en pacientes intubados y su asociación con el motivo de hospitalización / Evaluation of oral lesions in intubated patients and its association with the reason of hospitalization

asistencia ventilatoria cuando la vía aérea y la consciencia están comprometidas. Los elementos utilizados en este procedimiento se encuentran en contacto directo con estructuras dentofaciales, causando diversos tipos de lesiones, principalmente bucales. Aunque existen cuidados clínicos durante procesos de intubación, hay poca información, particularmente de la zona norte del país donde se hayan evaluado las posibles asociaciones entre los motivos de consulta más frecuentes y las diversas características, tanto clínicas como no clínicas de pacientes que han sido intubados. Objetivo: Identificar las alteraciones bucodentales más frecuentes en pacientes intubados, así como explorar las posibles asociaciones de acuerdo con los motivos de intubación más frecuentes. Material y métodos: Se realizó un estudio observacional, transversal y comparativo en el cual se evaluaron alteraciones bucodentales y sistémicas de pacientes intubados. Los grupos de estudio se desarrollaron de acuerdo con el motivo de intubación y la determinación de las asociaciones fue con cada una de las alteraciones bucodentales y sistémicas. Resultados: El motivo de intubación más frecuente fue el evento cerebral vascular (EVC) y las alteraciones dentofaciales más prevalentes fueron caries, lengua saburral y cálculo dental, entre otras. Además, se encontraron diferencias significativas entre pacientes con EVC, mostrando una mayor frecuencia en tabaquismo, hipertensión arterial y diabetes mellitus, así como en la presencia de gingivitis y úlceras. Pacientes con traumatismo craneoencefálico (TCE) tuvieron mayor frecuencia en la presencia de periodontitis. Conclusión: El motivo de hospitalización y las condiciones sistémicas preexistentes pueden ser un factor de riesgo para desarrollar lesiones bucales específicas antes y durante el periodo de intubación (AU)

Introduction: Intubation is a procedure that allows ventilatory assistance when the airway and consciousness are compromised. The elements used in this procedure are in direct contact with dentofacial structures causing various types of injuries, mainly oral. Although there is clinical care during intubation processes, there is little information, particularly from the northern part of the country where the possible associations between the most frequent reasons for consultation and the various clinical and non-clinical characteristics of patients who have been intubated have been evaluated. Objective: The objectives of the present study were to identify the most frequent oral alterations in intubated patients, as well as to explore possible associations according to the most frequent reasons for intubation. Material and methods: An observational, cross-sectional and comparative study was carried out in which oral and systemic alterations of intubated patients were evaluated. The study groups were formed according to the reason for intubation and the association was determined with each of the oral and systemic disorders. Results: The most frequent reason for intubation was the vascular cerebral event (CVA) and the most prevalent dentofacial alterations were caries, coated tongue, and dental calculus, among others. In addition, significant differences were found between patients with CVA, showing a higher frequency in smoking, hypertension, and diabetes mellitus, as well as in the presence of gingivitis and ulcers. Patients with traumatic brain injury (TBI) had a higher frequency in the presence of periodontitis. Conclusion: The reason for hospitalization and pre-existing systemic conditions can be a risk factor for developing specific oral lesions before and during the intubation period (AU)

Tinción con azul de toluidina en biopsia dirigida de lesiones displásicas de la mucosa bucal: informe de casos clínicos / Toluidine blue guided biopsy of dysplastic lesions of the oral mucosa: clinical cases report

Objetivo: Los desórdenes de mucosa bucal potencialmente malignos pueden presentar áreas displásicas. En estos casos, la biopsia es un procedimiento imprescindible para un correcto diagnóstico. La inspección visual y la palpación, como método de selección del área de biopsia, ofrecen sensibilidad y especificidad adecuadas pero mejorables. El objetivo de este artículo es presentar una serie de casos clínicos en los que se describen el empleo y la interpretación de la tinción vital con azul de toluidina como método complementario para contribuir a una mejor elección del área de biopsia. Casos clínicos: Se trata de siete casos de lesiones con sospecha de displasia epitelial en mucosa bucal. En cada uno se detalla la correlación de las áreas teñidas con las manifestaciones clínicas y con el diagnóstico de displasia. Además, se muestran patrones de tinción considerados falsos positivos. En la interpretación de la tinción positiva, se tuvieron en cuenta el aspecto superficial y el color de la lesión teñida. El empleo combinado de inspección, palpación y tinción vital podría constituir un procedimiento integral de utilidad para obtener mayor precisión en la determinación del sitio de biopsia en comparación con los mismos procedimientos aplicados de manera individual. En la interpretación de la tinción positiva con azul de toluidina deberían considerarse el aspecto superficial y el color de la lesión teñida (AU)

Aim: Potentially Malignant Disorders in the oral cavity can present dysplastic areas. In these cases, the biopsy is an essential procedure for a correct diagnosis. Visual inspection and palpation, are adequate methods to select the area for the biopsy, however there is margin for improvement. The objective of this article is to present a series of clinical cases in which the use and interpretation of vital staining with Toluidine Blue is described as a complementary method to contribute to a better choice of the biopsy area. Clinical cases: Seven clinical cases that presented lesions with suspected epithelial dysplasia in the oral mucosa were presented. The correlation of the stained areas with the clinical manifestations and with the diagnosis of dysplasia is detailed in each case. Staining patterns considered false positives are also shown. In the interpretation of the positive staining, the superficial appearance and color of the stained lesion were considered. The combined use of inspection, palpation and vital staining could constitute a useful comprehensive procedure to obtain greater precision in determining the biopsy site in relation to the same procedures applied individually. In the interpretation of the positive staining with Toluidine Blue, the superficial appearance and color of the stained lesion should be considered (AU)

Histoplasmosis: informe de un caso / Histoplasmosis: a case report

Objetivo: Describir el diagnóstico y el tratamiento interdisciplinario de un caso clínico de histoplasmosis. Caso clínico: Un paciente masculino de 39 años, con antecedentes de consumo de drogas, alcohol, tabaquismo crónico y VIH+ sin adherencia al tratamiento, acudió al Servicio de Odontología por una interconsulta del Servicio de Clínica Médica para la evaluación de lesiones erosivas en paladar duro y blando, reborde alveolar anterior, dorso lingual y lesión tumoral en encía anterosuperior. El diagnóstico definitivo se obtuvo por medio del análisis de muestras de biopsia transbronquial, lavado broncoalveolar y biopsia de lesión en piel. El paciente recibió tratamiento sistémico con antimicóticos (anfotericina B e itraconazol según esquema) y tratamiento local con colutorio de clorhexidina al 0,12% y 100.000 UI de nistatina en suspensión. Al momento del alta, presentaba una considerable mejoría de su estado general y de las lesiones orales, con disminución de sintomatología dolorosa. Se indicó turno para control a los 7 días de forma ambulatoria, al cual el paciente no asistió. El abordaje interdisciplinario y el análisis de los diferentes aspectos socioeconómicos, culturales, ambientales y sistémicos del paciente facilitaron el diagnóstico temprano de la enfermedad (AU)

Aim: To describe the diagnosis and interdisciplinary treatment of a clinical case of histoplasmosis. Clinical case: 39-year-old male patient with a history of drug abuse, alcohol, and chronic smoking, HIV+ without treatment compliance, attends the dental department referred by the medical department for the diagnosis of erosive lesions in the hard and soft palate, anterior alveolar ridge, lingual dorsum and tumor lesion in the anterosuperior gingiva. The definitive diagnosis was obtained by the analysis of transbronchial biopsy, bronchoalveolar lavage and skin lesion biopsy. The patient received systemic treatment with antifungals (amphotericin b, itraconazole according to protocol), and local treatment with 0.12% chlorhexidine mouthwash and 100,000 IU nystatin suspension. At the time of medical discharge, the patient presented a considerable improvement in his general condition and of the oral lesions with a reduced pain. A 7 days recall was prescribed, however the patient failed to attend. The interdisciplinary approach to the patient and the analysis of the different socio-economic, cultural, environmental and systemic aspects of the patient facilitates the early diagnosis of the disease (AU)

Eficácia do propionato de clobetasol 0, 05 nas lesões ulceradas da cavidade bucal / Efficacy of 0.05% clobetasol propionate in ulcerated lesions of the oral cavity

O uso tópico de Propionato de Clobetasol 0,05% em solução aquosa para lesões ulceradas na cavidade bucal é pouco divulgado nacionalmente e tem sido pouco citado em traba-lhos científicos a respeito de sua eficácia, tempo de regressão da lesão e efeitos adversos. Portanto, o objetivo deste estudo foi avaliar retrospectivamente prontuários de pacientes que foram tratados de lesões ulceradas através do uso do Propionato de Clobetasol 0,05%, no ambulatório de estomatopatologia de uma Instituição, a fim de investigar sua eficácia. Foram selecionados prontuários de pacientes que apresentaram a alteração fundamental ulcerada ou erosiva e que fizeram o uso tópico de Propionato de Clobetasol 0,05%. A aná-lise retrospectiva foi feita por um examinador, que fez a seleção da amostra seguindo os critérios de inclusão e exclusão. Foram coletadas as informações: Idade, gênero, diagnós-tico da alteração; quantidade de lesão, tempo de uso, evolução da lesão, tempo exato de regressão e presença de reações adversas. Foram incluídos 17 prontuários, dos quais cinco eram de pacientes com lesões erosivas de líquen plano, três úlceras traumáticas, três lesões liquenóides, dois eritemas multiformes, uma alergia a lactose, uma afta e uma gengivite descamativa. Todos os casos apresentaram resolução da sintomatologia, porém as altera-ções clínicas permaneceram em seis casos, embora mais leves e assintomáticas. Não foi ob-servada nenhuma reação adversa registrada no prontuário. A análise estatística não apontou associação em relação ao sexo (teste Exato de Fisher; p=0,49; p>0,05). Não foi observada diferença estatística significativa na frequência das lesões (teste exato de Fisher; p= 0,85; p>0,05). O uso do Propionato de Clobetasol 0,05% prescrito por até cinco dias se mostrou eficaz no tratamento de lesões ulceradas da mucosa bucal, principalmente para o alívio sintomático, além disso, não revelou efeitos adversos.

The treatment of ulcerated lesions of the oral cavity is usually carried out using topical analgesic drugs, anti-inflammatory corticosteroids, and alcohol-free oral antiseptics. The topical use of 0.05% Clobetasol Propionate in aqueous solution for ulcerated lesions in the oral cavity is little publicized nationally and little mentioned in scientific studies regarding its effectiveness, lesion regression time, and adverse effects. Therefore, the objective of this study was to retrospectively evaluate the medical records of patients who were treated for ulcerated or erosive lesions, using Clobetasol Propionate 0.05%, in the stomatology clinic of an institution to investigate its effectiveness. Medical records of patients who presented the fundamental ulcerated alteration and made topical use of 0.05% Clobetasol Propionate were selected. An examiner selected the sample following the inclusion and exclusion cri-teria and performed the retrospective analysis. The types of information collected were age, gender, diagnosis of the disorder, amount of injury, time of use, the evolution of the injury, exact time of regression, and presence of adverse reactions. A total of 17 medical records were included, of which five were from patients with erosive lichen planus lesions, three traumatic ulcers, three lichenoid lesions, two multiform erythema, one lactose allergy, one cold sore, and one scaly gingivitis. All cases had their symptoms solved, but, in six cases, the clinical changes remained, although milder and asymptomatic. No adverse reaction was noted in the medical record. The statistical analysis showed no association in relation to gender (Fisher's exact test; p = 0.49; p> 0.05). There was no statistically significant diffe-rence in the frequency of injuries (Fisher's exact test; p = 0.85; p> 0.05). The use of 0.05% Clobetasol Propionate, prescribed for up to five days, proved effective in treating ulcerated lesions of the oral mucosa, mainly for symptomatic relief. Furthermore, it revealed no ad-verse effects.

A relação da prematuridade e baixo peso ao nascer com lesões de mucosa oral em recém-nascidos e prevalência de anquiloglossia de acordo com critérios diagnósticos / The relationship of prematurity and low birth weight with oral mucosal lesions in newborns and prevalence of ankyloglossia according to diagnostic criteria

Objetivo: 1) verificar a associação da prematuridade e baixo peso ao nascimento (BPN) com a ocorrência de lesões de mucosa oral em recém-nascidos (RN), fatores de saúde materno-infantil e socioeconômicos, por meio de um estudo transversal; e 2) avaliar a prevalência de anquiloglossia em bebês, crianças e adolescentes de acordo com diferentes critérios diagnósticos, por meio de uma revisão sistemática. Métodos: 1) O estudo contou com uma amostra de 431 pares de mães e recémnascidos. A coleta foi realizada no período de agosto de 2016 a abril de 2017. Após o nascimento, os bebês tiveram a cavidade bucal examinada para lesões de mucosa. A regressão logística bivariada e multivariada foi utilizada para a análise dos dados. O nível de significância foi de 5%. 2) Foram realizadas buscas eletrônicas em nove bases de dados até 2021. Por meio da meta-análise de efeitos aleatórios, foi avaliada a prevalência bruta de anquiloglossia e para sexo. Uma metaanálise de efeitos mistos foi usada para análise de sugrupos por critérios diagnósticos e idade. Calculamos a RP e o IC de 95% da ocorrência de anquiloglossia em meninos, em comparação com meninas e avaliamos a certeza das evidências usando a abordagem GRADE. Resultados: 1) Prematuridade e BPN foram associados com pérolas de Epstein (odds ratio [OR]: 1,7; intervalo de confiança de 95% [IC]: 1,03­3,0; OR: 1,8; IC95%: 1,1­3,2, respectivamente) e mucocele (OR: 4,6; IC95%: 1,3­16,1; OR: 3,7; IC95%: 1,1­13,1, respectivamente), mas não à anquiloglossia (OR: 1,0; IC95%: 0,5­2,1; OR: 0,7; IC95%: 0,3 -1,6, respectivamente) ou amamentação (OR: 0,5; IC95%: 0,1-2,1; OR: 1,9; IC95%: 0,2- 15,6, respectivamente). A prematuridade foi associada à gravidez de alto risco (OR: 2,3; IC 95%: 1,3­3,9), estar na incubadora (OR: 3,2; IC 95%: 1,7­5,9) e baixo nível socioeconômico (OR: 2,4; IC de 95%: 1,1-5,2). 2) Setenta e três estudos observacionais foram incluídos (72 na meta-análise). Havia cinco diferentes critérios diagnósticos validados. A prevalência geral bruta de anquiloglossia foi de 4% (IC95%: 3% - 4%) variando de 67% para o critério de Coryllos (IC95%: 40% - 94%) a 2% para estudos que usaram critérios próprios (2%; IC95% : 2% - 2%). A prevalência foi similar entre faixas etárias e sexos. Entretanto, meninos tiveram 1,29 mais risco de ter anquiloglossia do que meninas (95%IC: 1,04-1,59) com muito baixa certeza de evidência. Conclusão: 1) Recém-nascidos prematuros e com BPN foram mais propensos a ter pérolas de Epstein e mucocele do que RN à termo e com peso normal. Amamentação e anquiloglossia não foram associadas à prematuridade e BPN. A prematuridade também foi associada à gravidez de alto risco, estar na incubadora e baixo nível socioeconômico. 2) A prevalência de anquiloglossia geral foi baixa, e maior para critérios diagnósticos validados comparado aos critérios próprios usados pelos autores. A prevalência de anquiloglossia foi semelhante para grupos de idade e sexo. Com muita baixa certeza da evidência, não podemos afirmar que meninos têm mais anquiloglossia que meninas.

Objective: This thesis describes two studies with the following objectives: 1) one cross-sectional study that aimed to associate prematurity and birth weight with the occurrence of oral mucosal lesions in newborns and associated factors, and 2) one systematic review that evaluated the prevalence of ankyloglossia in babies, children and adolescents according to different diagnostic criteria. Methods: 1) In the crosssectional study, the sample comprised 431 pairs of mothers and newborns born at the University Hospital of Federal University of Minas Gerais. The study included mothers and newborns present in the hospital from August 2016 to April 2017. We excluded newborns with congenital anomalies or syndromes. A trained and calibrated dentist examined the mouth of the newborns for oral mucosal lesions (Kappa = 0.90). The lesions evaluated were dental lamina cysts, Bohn's nodules, Epstein's pearls, mucocele and ankyloglossia. Mothers answered a self-administered questionnaire related to socioeconomic indicators and prenatal habits. Medical records were evaluated to collect information about prematurity, low birth weight (LBW), pregnancy, childbirth, postpartum, maternal and newborn health conditions. Bivariate and multivariate logistic regression were used for data analysis. The level of significance was 5%. 2) For the systematic review, nine electronic databases were searched from interception up to May 2021 with no restrictions imposed regarding on year of publication or language. Paired independent reviewers selected studies, extracted data, and assessed the risk of bias. Using random-effects meta-analysis, we pooled the crude prevalence of ankyloglossia in general and by sex. Using mixed effect-meta-analysis, we subgrouped by diagnostic criteria and age. We calculated the PR and 95%CI of the occurrence of ankyloglossia in boys compared to girls, and assessed the certainty of evidence using the GRADE approach. Results: 1) Prematurity and LBW were associated with Epstein pearls (odds ratio [OR]: 1.7; 95% confidence interval [CI]: 1.03­3.0; OR: 1.8; 95%CI: 1.1­3.2, respectively) and mucocele (OR: 4.6; 95%CI: 1.3­16.1; OR: 3.7; 95%CI: 1.1­13.1, respectively), but not to ankyloglossia (OR: 1.0; 95%CI: 0.5­2.1; OR: 0.7; 95%CI: 0.3­1.6, respectively) or breastfeeding (OR: 0.5; 95%CI: 0.1-2.1; OR: 1.9; 95% CI: 0.2­ 15.6, respectively). Prematurity was associated to high-risk pregnancy (OR: 2.3; 95% CI: 1.3­3.9), being in the incubator (OR: 3.2; 95% CI: 1.7­5,) and low socioeconomic status (OR: 2.4; 95% CI: 1.1-5.2). 2). 2) Seventy-three observational studies were included in the systematic review (72 in the meta-analysis). There were five different validated diagnostic criteria for ankyloglossia. The overall crude prevalence of ankyloglossia was 4% (95%CI: 3%-4%) varying from 67% for Coryllos criteria (40%- 94%) to 2% for those studies using own criteria (2%; 95%CI: 2%-2%). There was a similar prevalence for age groups and both sexes. Boys had 1.29 more risk of having ankyloglossia (95%CI: 1.04-1.59) with very low certainty. Conclusion: 1) Preterm and LBW newborns were more likely to have Epstein pearls and mucocele than full terms. Breastfeeding and ankyloglossia were not associated with prematurity and LBW. Prematurity was also associated with high-risk pregnancy, being in the incubator and low socioeconomic status. 2) The prevalence of ankyloglossia varied among all instruments used; with validated diagnostic criteria showing higher prevalence and non-validated or own criteria showing low prevalence. With low certainty, we could not affirm that boys are more prone to have ankyloglossia compared to girls.

Oral Health Consequences of Use of Smokeless Tobacco in North India: A Cross-Sectional Survey

ABSTRACT Objective: To evaluate the effects of commonly used smokeless tobacco forms on oral health at habitual placement sites of smokeless tobacco compared to non-placement sites among the North Indian population. Material and Methods: This cross-sectional study was conducted among 542 individuals using smokeless tobacco recruited from the outpatient wing of the Dental College. Subjects completed a questionnaire and received an oral examination. Periodontal pocket depth, gingival index, plaque index, gingival recession, and oral mucosal changes were assessed. Kendal's Tau test, paired t-test, and chi-square test were carried out to compare different variables among placement and non-placement sites. Results: Most of the subjects were male, reporting an average of 11.26 years of SLT use. Clinical inflammation of gingiva was significantly greater (p=0.01) at placement-sites (1.64 ± 0.53) of SLT in comparison to non-placement-sites (1.40 ± 0.41). The difference in the GR and PPD at placement and non-placement-sites was also statistically significant with p=0.002 and p=0.001, respectively. Clinically, the majority of subjects had mucosal changes at the placement sites, and a statistically significant association (p=0.034) was observed between the duration of the use of smokeless tobacco and the mucosal changes. Conclusion: Smokeless tobacco use predisposes to increased risk of periodontal diseases and oral mucosal changes at the placement sites in an individual due to the local irritant effect.

This article analyzes the results obtained by national research groups in the implementation of the Russian State Cancer Program. From 2015 to the first half of 2019, specialists studied the epidemiology and structure of oncological and precancerous diseases of the oral mucosa and the vermillion border in 486,059 persons aged 18-92 years living in Tula, the Tula region, Moscow and Noyabrsk as a result of screening and medical aid appealability. In this period, the productivity of the research group from Tula grew by the factor of 18.92. The results of the research confirm low cancer alertness of practicing dentists. An individual patient registration card has been developed to systematize data and create a diagnostic register for the screening of cancer and precancerous diseases of the oral mucosa and the vermillion border.

Prevalencia de lesiones bucales en tejido blando encontradas en la Clínica de Estomatología de la Facultad de Odontología de la Universidad de los Andes: periodo 2015-2018 / Prevalence of oral lesions in soft tissue found in the Clinic of Stomatology of the Faculty of Dentistry of the University of los Andes: 2015-2018 period

Introducción: La epidemiología sobre alteraciones en tejidos blandos bucales es limitada cuando se compara con caries, enfermedades periodontales y maloclusiones, por lo que su estudio representa un paso adelante en la odontología más allá de los dientes. Objetivo: Describir la prevalencia de las lesiones bucales en tejido blando encontradas en la Clínica de Estomatología de la Facultad de Odontología de la ULA, del 2015 al 2018, con la finalidad de proporcionar una fuente de datos actualizada, que oriente a una mejor prevención y oportuno diagnóstico. Material y métodos: Se realizó una investigación descriptiva, documental, retrospectiva y multivariable. Resultados: De 1,000 fichas clínicas estudiadas, las patologías más frecuentes fueron: lengua saburral (50.6%), queilitis (33.4%), traumatismo de la mucosa de los carrillos (27.6%), várices linguales (18.3%), anquiloglosia (13.7%) y agrandamiento de rugas palatinas (11.7%). La zona con mayor alteración fue la lengua (92.1%), mientras que el paladar fue la menos afectada (29%). De los hábitos predisponentes a la formación de lesiones, el mordisqueo de mucosa fue el más común (16.5%). En cuanto a los factores locales asociados, una higiene oral regular/ deficiente resultó el principal (53.8%). Conclusión: La educación del paciente sigue siendo considerada la clave para disminuir la aparición de patologías y su evolución a entidades más graves (AU)

Introduction: Epidemiological studies on soft tissue alterations in the mouth are limited when compared with caries, periodontal diseases and malocclusions, so their study represents a step forward in dentistry beyond the teeth. Objective: To describe the prevalence of soft tissue oral lesions found in the Stomatology Clinic of the ULA School of Dentistry, from 2015 to 2018, in order to provide an up-to-date data source, to guide better prevention and timely diagnosis. Material and methods: A descriptive and documentary, retrospective and multivariable research was carried out. The statistical package IBM SPSS Statistics v 23 was applied for the analysis. Results: 1,000 clinical records studied, the most frequent pathologies were: saburral tongue (50.6%), cheilitis (33.4%), traumatism of the cheek mucosa (27.6%), lingual varices (18.3%), ankyloglossia (13.7%) and enlargement of palatal rugas (11.7%). The tongue was the most affected (92.1%), while the palate was the least affected (29%). Of the predisposing habits to the formation of lesions, mucosal nipping was the most common (16.5%). Regarding the associated local factors, a regular / deficient oral hygiene was the main one (53.8%). Conclusion: Patient education is still considered the key to diminish not only the appearance of pathologies but their evolution to more serious entities (AU)
