Gingival cyst of the adult

ABSTRACT The gingival cyst of the adult (GCA) is a rare odontogenic cyst, consisting of 0.3% of all odontogenic cysts. This case report, based on CARE guidelines for case reports, aims to present a case of a 52-year-old female patient with a symptomatic translucent nodule in the upper left anterior gingiva, measuring approximately 6mm. Excisional biopsy was performed, and the histological examination revealed multiple cystic cavities lined by the squamous epithelium of varying thickness with focal areas of nodular thickenings. The presence of clusters of cells with clear cytoplasm within epithelial thickenings was observed. PAS staining was negative in clear cells. The diagnosis of the GCA was established. Despite its rarity, GCA should be considered in the differential diagnosis of gingival lesions. Conservative surgical treatment proved to be effective, with no signs of recurrence.

Association between the Mediterranean Diet Index and self-reported Gingival Health Status Indicators in a population of Chilean adults: a cross-sectional study

Abstract Despite the recognized impact of diet on non-communicable diseases, the association between the Mediterranean diet and periodontal diseases is still uncertain. This study aimed to determine the association between adherence to the Mediterranean Diet Index (MDI) and self-reported gingival health status in Chilean adults, exploring the feasibility of using validated web-based survey questionnaires. Methodology Cross-sectional data were collected from a representative sample of a population of Chilean adults (18-60 years old) using a low-cost and time-saving methodology. By the PsyToolkit platform, anonymous survey data were downloaded and analyzed in bivariate (crude) and backward stepwise selection multivariate logistic regression models adjusted for sociodemographic determinants, smoking, and dental attendance using STATA 17. Odds ratios (OR) [95% confidence intervals] were estimated. Results In total, 351 complete statistical data were mostly obtained from female university students who had never smoked and reported having visited a dentist in the previous year. Multivariate regression models showed an association between MDI and very good/good gingival health status (OR 1.18 [95% CI 1.04-1.34], p=0.013), absence of bleeding on toothbrushing (OR 1.12 [95% CI 1.01-1.25], p=0.035), and absence of clinical signs of gingival inflammation (OR 1.24 [95% CI 1.10-1.40], p<0.001), after controlling for age, sex, educational level, smoking, and dental attendance. Conclusions We associated adherence to the Mediterranean diet with better self-reported gingival health status in a population of Chilean adults in an entirely web-based research environment. Longitudinal studies with random sampling are required to establish the effect of diet on gingival and periodontal health. Nevertheless, this evidence could contribute to the design of low-cost surveillance programs to reduce the burden of periodontal disease and related "common risk factors".

Periodontal disease and its impact on general health in Latin America: LAOHA Consensus Meeting Report

Abstract: Periodontal diseases are considered a worldwide public health problem, owing to their high prevalence in developed and developing countries. Periodontitis may lead to tooth loss, which can impact oral health-related quality of life. Gingivitis and periodontitis have been extensively studied regarding their etiopathogenesis, epidemiology, prevention and treatment outcomes. However, most of these aspects are studied and discussed globally, which may hamper a clear interpretation of the findings and the design of effective plans of action for specific regions or populations. For example, in Latin America, epidemiological data about the distribution of periodontal diseases is still scarce, mainly when it comes to nationwide representative samples. This Consensus aimed to address the following topics related to periodontal diseases in Latin America: a) The impact of the global burden of periodontal diseases on health: a global reality; b) Periodontal diseases in Latin America; c) Strategies for the prevention of periodontal diseases in Latin America; d) Problems associated with diagnosis of periodontal conditions and possible solutions for Latin America; e) Treatment of Periodontitis. This consensus will help to increase awareness about diagnosis, prevention and treatment of periodontal diseases, in the context of Latin American countries.

Congenital granular cell epulis: case report and differential diagnosis / Epúlide de células granulares congênita: relato de caso e diagnóstico diferencial

ABSTRACT A 16-days-old female patient exhibiting an exophytic nodular lesion located at anterior maxilla on the alveolar ridge since birth. The clinical hypothesis of congenital granular cell epulis (CGCE) was established, and the patient underwent excisional biopsy. Microscopically, a sheet-like proliferation of eosinophilic cells with granular cytoplasm was observed in a stroma of vascularized fibrous connective tissue. The immunohistochemical analysis for S100 evidenced the absence of immunostaining. The CGCE hypothesis was confirmed and, after six months, the patient showed no signs of recurrence of the lesion.

Clinical evaluation and comparison of three surgical procedures for treatment of root surface exposure after epulis resection / 中华口腔医学杂志

Objective@#To evaluate and compare the clinical effects of three surgical procedures for the periodontal treatment of root surface exposure after resection of epulis.@*Methods@#Thirty patients with epulis were selected in this study and the exposed root surfaces of the patients′ teeth were covered with laterally transposition flap, laterally pedicled transposition flap or coronally advanced flap combined with a connective tissue graft in the treatments of epulis. At the time of follow-up during the operation, 3 months after operation and 6 months after operation, respectively, the color, shape and quality of the gum in the operation area and the coordination of the diaphragm and diaphragm were observed, and the root surface exposure (recession depth, RD) and angle were recorded. Keratinized tissue height (KTH), root coverage rate (RC) and patients′ satisfaction with the surgery were also recorded.@*Results@#The flap widths in groups of laterally pedicled transposition flap and coronally advanced flap combined with a connective tissue graft were significantly wider than that in the group of laterally transposition flap at three-month and six-month follow-ups after the surgery. The width of keratoderma [(2.70±1.16) mm] in the group of laterally transposition flap was significantly lower at 6 months postoperatively than that in the other two groups [(4.80±1.14) and (4.90±1.66) mm, respectively] (P<0.01). At the 6th month after surgery, the root flap coverage was at the lowest level [(24±43)%] in the group of laterally transposition flap, and it was significantly lower than that in the other two groups [(80±23)% and (86±24)%, respectively] (P<0.01). There was no significant difference of the root flap coverage between groups of laterally pedicled transposition flap and coronally advanced flap combined with a connective tissue graft. At the time of follow-up, patients were satisfied with the aesthetic effects of the three surgical procedures.@*Conclusions@#After the resection of the gingival tumor, the defect of the gingiva is caused. The laterally pedicled flap and pedicled flap combined with connective tissue transplantations for soft tissue repairing can achieve satisfactory aesthetic effects which are superior to the effect of simple flap technique.

Plaque-induced gingivitis was the most common (58.2%), while moderate gingival inflammation affected 67% of the students with localized gingival inflammation involving 64.7% of the participants. Conclusion: The prevalence of gingivitis was high, so that early and correct management of this condition in children avoids complications and requires good oral hygiene.

Vestibuloplastia con la técnica de Edlan Mejchar: descripción de cuatro casos clínicos / Vestibuloplasty with Edlan Mejchar technique: description of four clinical cases

Antecedentes: En ocasiones, las retracciones gingivales se asocian a altas fuerzas tensionales de los músculos y a vestíbulos poco profundos. Dichas retracciones generan problemas periodontales a los pacientes por la dificultad de limpiar estas zonas. La vestibuloplastia por medio de la técnica de Edlan Mejchar permite, en una sola intervención y un solo campo quirúrgico, controlar los factores etiológicos y una inserción trepadora de la encía al eliminar las fuerzas tensionales. Objetivo: Describir la efectividad de la técnica de Edlan Mejchar empleada para solucionar retracciones gingivales producidas por fuerzas tensionales en cuatro casos clínicos. Descripción de los casos: Se presentaron cuatro pacientes con retracciones gingivales en dientes incisivos inferiores con poca encía adherida debida a fuerzas tensionales del frenillo labial inferior. Como tratamiento se usó la técnica de Edlan Mejchar que incluyó una incisión supraperióstica y relajantes internas en el tejido conjuntivo. Resultados: El porcentaje de cobertura radicular logrado después del procedimiento fue de aproximadamente el 60 % y se eliminaron inserciones anómalas del frenillo. Conclusiones: La técnica de Edlan Mejchar de vestibuloplastia mostró resultados favorables en los casos descritos en los cuales el frenillo labial ejercía fuerzas tensionales sobre el periodonto de dientes anteriores inferiores.

Background: Sometimes gingival retractions are associated with high muscular tensional forces and shallow vestibules. Such retractions cause periodontal problems to patients due to the cleaning access limitations. Edlan Mejchar vestibuloplasty technique allows controlling, in one intervention and a single surgical field, etiological factors and a creeping gingival attachment by eliminating tensional forces. Purpose: To describe the effectiveness of Edlan Mejchar technique to solve gum retractions caused by tensional forces in four clinical cases. Description of cases: Four patients with gingival retractions in lower incisors and little adhered gingiva due to lower lip frenulum tension seek dental treatment. Edlan Mejchar vestibuloplasty was the surgical treatment chosen, which consisted of supraperiosteal incisions and internal dissections in connective tissue. Results: The percentage of root coverage achieved was close to 60 % and abnormal frenulum insertions were eliminated. Conclusion: Vestibuloplasty through Edlan Mejchar technique showed favorable results in the cases described in which the labial frenum exerted tensional forces on the periodontium of lower anterior teeth.

In this study, we summarized the treatment strategies in various types of gingival Stillman's cleft, so as to provide the reference for clinicians.

Agrandamiento gingival por ciclosporina: reporte de un caso / Gingival enlargement due to cyclosporine: a case report

El agrandamiento gingival (AG) es el aumento de volumen anormal de la encía que genera cambios estéticos y síntomas clínicos como sangrado gingival espontáneo o inducido, trastornos periodontales y migración patológica dentaria, entre otros. Este proceso patológico puede ser un efecto secundario a ciertos fármacos como anticonvulsivantes, bloqueadores de canales de calcio e inmunosupresores. Se presenta el caso de un paciente sexo masculino de 74 años de edad con antecedentes de trasplante renal, en tratamiento con ciclosporina, que acude por aumento del volumen intraoral, clínicamente compatible con agrandamiento gingival. Se realiza tratamiento basado en exodoncias, biopsia y control de placa. A los 2 meses se pudo observar una regresión de la lesión, y se confirma el diagnóstico con el estudio histopatológico. El manejo actual del tratamiento de esta enfermedad se basa en el control de la placa. Se sugiere dar un enfoque multidisciplinario y crear protocolos para derivar oportunamente antes de la expresión más agresiva de la enfermedad.

Gingival enlargement is an abnormal increased volume of the gum that induces cosmetic changes and clinical symptoms, such as gingival bleeding, periodontal disorders, pathological tooth migration, among others. This condition can be a side effect of certain drugs such as anticonvulsants, calcium channel blockers, and immunosuppressants. A 74 year-old male patient with a medical record of kidney transplant secondary to chronic renal failure receiving cyclosporine for the past 14 years is referred to our Hospital with the chief complaint of gingival enlargement. The treatment is based on tooth extractions, biopsy and periodontal treatment. A complete regression of the lesion was observed after two months. The current approach to treat this disease is focused on plaque control. A multidisciplinary approach should be used and clinical protocols prepared that allow early treatment and avoidance of more aggressive disease expression.

Prevalence, severity, and risk indicators of gingival inflammation in a multi-center study on South American adults: a cross sectional study

ABSTRACT Objectives: The aim of this study is to investigate the prevalence and severity of gingival inflammation and associated risk indicators in South American adults. Material and Methods: Multi-stage samples totaling 1,650 adults from Porto Alegre (Brazil), Tucumán (Argentina), and Santiago (Chile) were assessed. The sampling procedure consisted of a 4-stage process. Examinations were performed in mobile dental units by calibrated examiners. A multivariable logistic regression model was utilized for associating variables as indicators of gingival inflammation (GI) (Gingival Index ≥0.5). Statistical significance was set at 0.05. Results: A total of 96.5% of the adults have GI. Regarding the severity of GI, 22.5% of participants examined have mild GI, 74.0% have moderate GI, and 3.6% have severe GI. The multivariate analyses identify the main risk indicators for GI as adults with higher mean of Calculus Index (OR=18.59); with a Visible Plaque Index ≥30% (OR=14.56); living in Santiago (OR=7.17); having ≤12 years of schooling (OR=2.18), and females (OR=1.93). Conclusions: This study shows a high prevalence and severity of gingival inflammation, being the first one performed in adult populations in three cities of South America.

Gengivite descamativa por corpo estranho - um caso clínico atípico / Desquamative gingivitis by foreign-body - an atypical clinical case

A gengivite descamativa caracteriza-se por eritema doloroso, perda da camada superficial de queratina, com ou sem ulceração, na gengiva aderida. Não cede às medidas profiláticas convencionais. Paciente do sexo feminino, 55 anos, caucasiana, compareceu na FMDUP, com “dor e ardência nas gengivas”. Após diagnóstico clínico de gengivite descamativa iniciámos tratamento convencional. Foi realizada biópsia incisional para despiste: líquen plano, pênfigo, penfigóide e lúpus eritematoso. O resultado da biópsia revelou lesão liquenóide com infiltrado linfoplasmocitário e presença de corpo estranho. A histologia, e o facto de a doente não apresentar melhoras com a aplicação de corticóide tópico, à excepção da zona biopsada, favoreceu a hipótese de gengivite descamativa por corpo estranho. Paciente foi aconselhada a fazer controlos trimestrais. Pacientes com estas manifestações deverão proceder a um bom controlo de placa bacteriana e descartar outras fontes de inflamação. A remissão da doença, só se consegue totalmente com a eliminação cirúrgica da gengiva afectada.

Desquamative gingivitis is a descriptive term that refers to an erythematous appearance of the gingiva, characterized by loss of keratin, with or without ulceration, and painprophylactic measures won´t restrain symptoms. 55 year-old woman, caucasian, came to FMDUP with pain and burn on the gingiva. Clinical diagnosis of desquamative gingivitis was followed by convencional treatment. Incisional biopsy was performed after verifying the insuccess of convencional measures: lichen planus, pemphigus, pemphigoid, lupus erythematosus were considered. The biopsy unfolded a lichenoid lesion with lymphocytic infiltrate and presence of foreign body. This diagnosis in association with the lack of improvement after topic application of corticosterois, favored the hypothesis of desquamative gingivitis associated with foreign body. The patient was advised to attend to quarterly appointments. Patients with these clinical manifestations, must have a perfect plaque control, allowing to discard other sources of inflammation. Cure is only complete with surgical removal of the affected gingiva.

Effect of chlorhexidine varnish on gingival growth in orthodontic patients: a randomized prospective split-mouth study

Introduction: Fixed orthodontic appliances patients suffer limitations on the effective control of biofilm by mechanical methods, bringing the need of a coadjutant in the control of inflammation and oral health improvement.Objective: The aim of this prospective split-mouth blind study was to analyze the effect of a 40% chlorhexidine (CHX) varnish on gingival growth of patients with orthodontic fixed appliances. Methods: Healthy teenage patients with fixed orthodontic appliances and increased gingival volume were recruited (n = 30). Each individual was his own control, having in the maxilla one control side and one treatment side. An application of varnishes occurred on the vestibular area of the upper premolars and first molar crowns, on the control side (placebo varnish) and on the experimental side (EC40(r) Biodentic CHX varnish). The varnishes and sides were randomly chosen and its identification and group was kept by a third party observer and it was not revealed to the researchers and participants until the end of study. In order to establish a baseline registration, digital photographs were taken by a trained photographer before varnish application at baseline (T0), as well as 14 days (T14) and 56 days (T56) after the application. The gingival volume was calculated indirectly using the vestibular areas (mm2) of the upper second premolars' clinical crowns by RapidSketch(r) software, at all study times. The data were analyzed using ANOVA and the Turkey-Krammer test.Results:It was observed, in the final sample of 30 individuals, that at T0, the control and treatment groups were similar. At T14 and T56, a progressive reduction of the clinical crown area was seen in the control group, and an increase in the average area was detected in the experimental group (p < 0,05).Conclusions: The use of 40% CHX varnish decreases the gingival overgrowth in patients undergoing orthodontic treatment. Further studies are necessary to set the action time and frequency of application.

Introdução: pacientes com aparelhos ortodônticos fixos sofrem limitações no controle efetivo de biofilme por métodos mecânicos, trazendo a necessidade de um coadjuvante no controle na inflamação e melhora na saúde bucal.Objetivo:esse estudo cruzado prospectivo randomizado teve como objetivo analisar o efeito do verniz de clorexidina (CHX) a 40% no crescimento gengival de pacientes com aparelhos ortodônticos fixos.Métodos:indivíduos adolescentes com aparelhos ortodônticos fixos e aumento de volume gengival foram recrutados para a pesquisa (n = 30). Cada participante atuou como seu próprio controle, tendo, na maxila, um lado controle e um tratamento. No lado controle, aplicou-se verniz placebo e no lado experimental, o verniz EC40(r) Biodentic CHX, ambos na face vestibular das coroas dos pré-molares e primeiro molar superiores. Os vernizes e lados foram escolhidos de forma aleatória e a identificação deles e a que grupo pertenciam foi mantida por um terceiro observador, não sendo revelada aos pesquisadores nem aos participantes até o final do estudo. Fotografias digitais foram tiradas por um fotógrafo treinado, antes da aplicação do verniz no tempo inicial (T0), bem como 14 dias (T14) e 56 dias (T56) após a aplicação. O volume gengival foi calculado indiretamente, por meio das áreas vestibulares (mm2) das coroas dos segundos pré-molares superiores, com o softwareRapidSketch(r), em todos os tempos de estudo. Os dados foram analisados usando ANOVA e teste de Turkey-Krammer.Resultados:na amostra final de 30 indivíduos, observou-se que, em T0, os grupos controle e tratamento foram semelhantes. Já em T14 e T56, foi observada uma progressiva redução na área da coroa clínica no grupo controle, e um aumento na área média do grupo experimental (p< 0,05).Conclusão:o uso do verniz de CHX a 40% diminui o excessivo crescimento gengival em pacientes sob tratamento ortodôntico. Estudos futuros são necessários para se determinar o tempo de ação e a frequência de aplicação.

Presentación de una paciente con granuloma periférico de células gigantes / Presentation of a Patient with Peripheral Giant Cell Granuloma

Se presentó una paciente femenina de 37 años de edad, sin antecedentes generales de interés, con hábito de onicofagia desde la niñez, que presentaba aumento de volumen localizado en la papila interdentaria entre incisivo lateral y canino maxilar derecho, de aproximadamente dos años de evolución, que le ocasionaba molestias y sangramiento durante el cepillado dentogingival. La lesión se presentó con aspecto de una pieza dentaria, de coloración rosa a rojo, superficie lisa, base sésil, no doloroso a la palpación, rebasaba el borde incisal, sin interferir con la oclusión y sobrepasaba el ancho vestíbulo lingual de los dientes contiguos en aproximadamente dos milímetros. Radiográficamente se observó reabsorción superficial de la cresta del tabique interdentario entre ambos dientes y espaciamiento del trabeculado óseo. Se realizó la escisión quirúrgica y posterior examen anatomopatológico, el cual confirmó la presencia de granuloma periférico gigante celular completamente resecado, lo cual corroboró el diagnóstico presuntivo. Se apreció una satisfactoria evolución postquirúrgica.

A female patient of 37 years old with no history of general interest, nail biting habit from childhood, which had increased volume within the interdental papilla between lateral incisor and maxillary right canine about two years of evolution was presented, which caused discomfort and bleeding during dentogingival brushing. The lesion appeared with appearance of a tooth, pink color to red, smooth, sessile base, not painful on palpation, exceeded the incisal margin, without interfering with the occlusion and surpassing the broad lingual hall of the contiguous teeth in approximately two millimeters. The radiographic exam evidenced superficial reabsorption of the crest of the interdental partition between both teeth and bone-like spacing of the trabeculate. The lesion was eliminated by surgical excision. The histologic test confirmed the presence of peripheral giant cell granuloma completely eliminated. A satisfactory post-surgical evolution was observed.

RPS (REGISTRO PERIODONTAL SIMPLIFICADO): MÉTODO RÁPIDO E SIMPLES NA IDENTIFICAÇÃO PRECOCE DA DOENÇA PERIODONTAL / PSR (Periodontal Screening and Recording): fast and simple method for early identification of periodontal disease

Objetivo: Explanar sobre o RPS (Registro Periodontal Simplificado), um método simples e de fácil aplicação para a detecção precoce da doença periodontal, desenvolvido pela Academia Americana de Periodontologia (AAP) junto à Associação Dental Americana (ADA) em 1992. Métodos: Foi realizada uma revisão da literatura sobre o RPS em periódicos e artigos científicos nas bases de dados LILACS, BBO e SciELO. Resultados: Através do RPS pode-se avaliar o grau de necessidade de tratamento periodontal, tornando o exame periodontal inicial mais rápido e prático, além de favorecer a elaboração de uma estratégia de tratamento mais segura. O exame é realizado com a sonda periodontal preconizada pela Organização Mundial de Saúde, onde a boca do paciente é dividida em seis sextantes, os quais recebem códigos numerados (0 a 4) de acordo com a visibilidade da sonda no sulco e com determinadas características clinicas. O método parece encontrar grande valia, principalmente, quando se deseja otimizar o intervalo de tempo entre diagnóstico e tratamento. Conclusão: o RPS é um método rápido, simples, de baixo custo e eficiente na detecção precoce das doenças periodontais e, consequentemente, na prevenção de suas formas avançadas; contudo, em determinadas situações, não substitui o exame periodontal completo.

Aim: To explain about the PSR (Periodontal Screening and Recording), a simple and easy method to apply for early detection of periodontal disease, developed by the American Academy of Periodontology (AAP) and the American Dental Association (ADA) in 1992. Methods: A review was conducted on the RPS in journals and scientific articles in the databases LILACS, BBO and SciELO. Results: Through the PSR the degree of necessity of periodontal treatment can be evaluated, becoming the examination initial periodontal quicker and practical, beyond favoring the elaboration of a treatment strategy safer. The examination is carried through with the periodontal sounding recommended by the World Health Organization, where the patient's mouth is divided in six sextants that receive codes with numbers (0 from 4) with in accordance the visibility of the sounding lead in the gingival sulcus and with determined clinical features. The method seems to find very useful especially when it is desired to optimize the time interval between diagnosis and treatment. Conclusion: The PSR is rapid, simple, inexpensive and efficient to the early detection of periodontal diseases and, consequently, for the prevention of the advanced periodontal disease. However, it doesn't replace a complete periodontal examination.

Microscopia confocal a laser na avaliação in vivo da gengivite descamativa: padrões no penfigóide das membranas mucosas, pênfigo vulgar e líquen plano oral / Confocal microscopy in the in vivo evaluation of desquamative gingivitis: patterns in mucous membrane pemphigoid, pemphigus vulgaris and oral lichen planus

Introdução: Gengivite descamativa (GD) se refere a uma manifestação clínica associada com diversas doenças mucocutâneas. Suas causas mais comuns são penfigóide das membranas mucosas (PMM), pênfigo vulgar (PV) e líquen plano oral (LP). A diagnose específica é melhor estabelecida através de avaliação histopatológica e de imunofluorescência. Objetivos: Examinar casos de gengivite descamativa utilizando microscopia confocal a laser e comparar os achados com aqueles encontrados na gengiva normal. Além disso, comparar os achados de microscopia confocal da gengivite descamativa com os da histopatologia convencional das lesões biopsiadas a fim de estabelecer critérios para este método diagnóstico não invasivo. Método: Doentes com manifestações clínicas de gengivite descamativa foram incluídos, totalizando quarenta e três casos. A microscopia confocal foi realizada na gengiva de um indivíduo saudável e nas lesões gengivais. Todas as lesões sem exame histopatológico prévio foram biopsiadas a fim de permitir uma correlação entre a microscopia confocal e a histopatologia. Resultados: O exame de microscopia confocal das lesões suspeitas de penfigóide das membranas mucosas revelou uma separação ao nível da junção dermo-epidérmica, preenchida por pequenas estruturas brilhantes, interpretadas como hemáceas. Os aspectos histopatológicos e de imunofluorescência confirmaram o diagnose. Para os casos de pênfigo vulgar, os achados da microscopia confocal foram de fenda intraepitelial com células arredondadas interpretadas como queratinócitos acantolíticos. Hiperqueratose e espongiose, associadas com infiltrado inflamatório, caracterizado por células pequenas e brilhantes permeando a estrutura intraepitelial de queratinócitos conhecida como favo de mel foram vistos no líquen plano. Estruturas arredondadas pouco brilhantes, interpretadas como queratinócitos necróticos, e estruturas estelares também pouco brilhantes, interpretadas como melanófagos, foram encontrados...

Background: Desquamative gingivitis refers to a clinical manifestation associated with several mucocutaneous disorders. The most common are mucous membrane pemphigoid, pemphigus vulgaris and lichen planus. Their specific diagnosis is better established by histopathological and immunofluorescence evaluation. Objective: To examine cases of desquamative gingivitis using reflectance confocal microscopy and compare the findings with those of normal gingiva. Moreover, confocal microscopy findings in desquamative gingivitis were compared to conventional histopathology of the biopsied lesions, in order to establish criteria for this non-invasive diagnostic technique. Methods: Patients with clinical manifestations of desquamative gingivitis were included, totalizing forty-three cases. Reflectance confocal microscopy was performed the gingival of a healthy person and on gingival lesions. All lesions were biopsied in order to perform a reflectance confocal microscopy- histopathologic correlation. Results: Reflectance confocal microscopy exam of the gingival lesions suspected of mucous membrane pemphigoid revealed a separation at the level of dermal-epidermal junction, filled with small bright structures interpreted as blood cells. Histopathological and immunofluorescence aspects confirmed the diagnosis. For pemphigus vulgaris, reflectance confocal microscopy aspects were of intraepithelial cleft with round detached cells interpreted as acantholytic keratinocytes, similar to the histopathological features. Hyperkeratosis and spongiosis associated with infiltration of inflammatory cells, recognized as small bright cells intermingling the honeycomb keratinocyte epithelial structure, were seen in lichen planus. Mild bright round structures interpreted as necrotic keratinocytes and mild bright stellate structures, interpreted as melanophages in the dermis were also seen. These features were present in histopathology, confirming the diagnosis of lichen...
