Extraosseous Calcifying Odontogenic Cyst Initially Interpreted as a Parulis.

Extraosseous variants of odontogenic cysts are an infrequent clinical finding, although they have a relatively indolent biological behavior compared to their intraosseous counterparts; due to their nature and clinical appearance, these lesions can be confused with multiple entities that affect soft tissues, so their diagnosis can only be achieved through surgical removal and subsequent histopathological analysis. The extraosseous/peripheral variant of calcifying odontogenic cyst (E/PCOC) has a heterogeneous clinical presentation mainly in terms of size and involvement or not of adjacent anatomical structures such as bone and teeth; in addition, there are few cases reported to date; thus, there are still clinical features to be elucidated. This report presents a child affected by E/PCOC in an unusual location, as well as its therapeutic management, which at first time was suspected of endodontic nature, due to a history of dental trauma.

Self-Reported Periodontal Disease and Its Association with SARS-CoV-2 Infection.

Introduction: Knowledge of the oral manifestations associated with SARS-CoV-2 infection, the new coronavirus causing the COVID-19 pandemic, was hindered due to the restrictions issued to avoid proximity between people and to stop the rapid spread of the disease, which ultimately results in a hyperinflammatory cytokine storm that can cause death. Because periodontal disease is one of the most frequent inflammatory diseases of the oral cavity, various theories have emerged postulating periodontal disease as a risk factor for developing severe complications associated with COVID-19. This motivated various studies to integrate questions related to periodontal status. For the present work, we used a previously validated self-report, which is a useful tool for facilitating epidemiological studies of periodontal disease on a large scale. Methodology: A blinded case-control study with participants matched 1:1 by mean age (37.7 years), sex, tobacco habits and diseases was conducted. After the diagnostic samples for SARS-CoV-2 detection were taken in an ad hoc location at Guadalajara University, the subjects were interviewed using structured questionnaires to gather demographic, epidemiological and COVID-19 symptom information. The self-reported periodontal disease (Self-RPD) questionnaire included six questions, and subjects who met the criteria with a score ≥ 2 were considered to have periodontal disease. Results: In total, 369 participants were recruited, with 117 participants included in each group. After indicating the subjects who had self-reported periodontal disease, a statistically significant difference (p value ≤ 0.001) was observed, showing that self-reported periodontal disease (n = 95, 85.1%) was higher in SARS-CoV-2-positive individuals than in controls (n = 66, 56.4%), with an OR of 3.3 (1.8-6.0) for SARS-CoV-2 infection in people with self-reported periodontal disease. Cases reported a statistically higher median of symptoms (median = 7.0, Q1= 5.5, Q3 = 10.0) than controls (p value ≤ 0.01), and cases with positive self-RPD had a significantly (p value ≤ 0.05) higher number of symptoms (median = 8.0, Q1 = 6.0, Q3 = 10.0) in comparison with those who did negative self-RPD (median = 6.0, Q1 = 5.0, Q3 = 8.0). Conclusions: According to this study, self-reported periodontal disease could be considered a risk factor for SARS-CoV-2 infection, and these individuals present more symptoms.

Multiple calcifying hyperplastic dental follicles: a major diagnostic consideration in multiple pericoronal lesions - report of two cases.

BACKGROUND: Pericoronal radiolucent lesions are a common radiographic finding, but it is rare that they occur in multiple forms. Multiple calcifying hyperplastic dental follicles (MCHDF) are entities with few cases described to date; nevertheless, they appear to have a very particular phenotypic pattern. CASES PRESENTATION: Case 1: A 10-year-old male was evaluated radiographically, revealing four impacted canines, each accompanied by unilocular pericoronal radiolucency. Case 2: A 16-year-old male was planning orthodontic treatment; following his radiological evaluation all third molars were found to be accompanied with pericoronal radiolucencies. Enucleation, and third molar removal along with the pericoronal tissue were the respective treatments. Microscopically, in both cases, the specimens shown odontogenic epithelium, and type I and II calcifications in the hyperplastic follicles, all these characteristics were consistent with MCHDF. CONCLUSION: Although MCHDF are a rare entity, they must be considered in the differential diagnosis of multiple pericoronal lesions. Under the light of the current evidence, the histological findings may be relatively heterogeneous, but their integration with both the clinical data, which are apparently particular, and with the radiographic characteristics, can lead to a definitive diagnosis.

Experiencia de caries dental en trabajadores universitarios: su asociación con variables sociodemográficas / Caries experience in university workers: its association with sociodemographic data

Objetivo. Evaluar la experiencia de caries en trabajadores universitarios y su asociación con variables sociodemográficos. Métodos. Estudio transversal, observacional y analítico con un grupo de trabajadores de la Universidad de Guadalajara, México. Se recopilaron datos de las variables sociodemográficas mediante un cuestionario y a través del examen clínico el índice CPOD. Se realizaron pruebas estadísticas de Chi-cuadrado, t-Student, ANOVA de una vía y post-hoc con significancia de 0,05. Resultados. Doscientos no-venta participantes accedieron a la exploración oral, con un promedio de edad de 36,2 ± 0,6, 55,9% fueron mujeres. El CPOD de la muestra evaluada fue de 8,3±5,3. El análisis de Chi-cuadrado en la evaluación etaria y los niveles de CPOD mostraron significancia estadística (p=0,0001). De forma similar, en las pruebas de ANOVA de una vía en el grupo de hombres (p=0,0001) y en los que residen en Tonalá (p=0,022), el componente cariados del índice se vio significativamente aumentado. Se observó también, un índice aumentado de dientes obturados en los participantes con nivel máximo de posgrado (p=0,001). El grupo de fumadores mostró significancia estadística (p=0,034) en el índice de caries. Conclusiones.El índice CPOD poblacional se encontró en nivel bajo, estando el grupo de mayor edad significativamente por encima de los dos grupos de menor edad. Los niveles del componente cariados fueron más bajos en los habitantes de las regiones foráneas del estado y los que tenían escolaridad de posgrado (p=0,022 y p=0,02 respec-tivamente).

Objective. To evaluate caries experience in university workers and to associate it with sociodemographic data. Methods. It was performed a descriptive cross-sectional, ob-servational and analytic study in university workers from the University of Guadalajara, Mexico. Sociodemographic data was collected through a questionnaire and the DMFT index, through clinical evaluations. Statistical analysis of χ2, T-student, one-way ANO-VA and Post-hoc were performed working with CI of 95%. Results. 290 participants agreed to oral examination, the average age of the interviewed workers was 36.2 ± 0.6. Women represented 55.9%. The DMFT of the evaluated sample was 8.3± 5.3. The χ2 analysis of the evaluated age ratio, showed statistical significance (p=0.0001). Similarly, the decay component of the index was increased in the one-way ANOVA test of the male group (p=0,0001) and of those who reside in Tonala (p=0.022). Additionally, an increased number of filled teeth was found in participants with postgraduate education (p=0.001). The smokers group showed statistical significance (p=0.034) in caries index. Conclusions. The broad DMFT index was found at a low level, however, the older age group was significantly different, being at the high level, well above the two younger age groups. The caries component of the DMFT index was significantly lower in the out of the region residents and those who had postgraduate degree (p=0.022 and p=0.02 respectively).

Acantosis nigricans: importancia del odontólogo en el diagnóstico / Acanthosis nigricans: importance of the dentist in the diagnosis

La acantosis nigricans es un síndrome que afecta tanto la piel como las mucosas que se caracteriza por lesiones papilomatosas en mucosa bucal y alteraciones pigmentadas de la piel. Puede encontrarse con o sin asociación a neoplasia maligna, generalmente adenocarcinoma gástrico. Las manifestaciones bucales de este padecimiento, son más comunes cuando se encuentra asociada a neoplasia maligna y, se caracterizan por proliferaciones papilomatosas en labio, encías y lengua. El tratamiento es sintomático y al tratar la neoplasia subyacente se pueden llegar a resolver las lesiones de piel y de la boca. En el presente trabajo se describe un caso clínico asociado a adenocarcinoma de endometrio, destacando las manifestaciones bucales de la lesión de importancia para el estomatólogo de práctica general para que después de sea enviado al servicio correspondiente.

The acantosis nigricans is a syndrome that affects both the skin and the mucousas ones that are characterized by papilomatosus injuries in mucousae of the mouth and pigmented alterations of the skin. It can be with or without association to malignant neoplasia,, generally adenocarcinoma gastric. The mouth manifestations of this suffering, are more common when it is associated to malignant neoplasia and, are characterized by polilomatosus proliferations in lip, gums and tongue. The treatment is symptomatic and on having treated the neoplasia there can manage to be solved the injuries of skin and of the mouth. In the present work a clinical case is described, emphasizing the mouth manifestations of the injury of importance for the dentist for a good channeling of patiently and suitable attention.

Intravascular Papillary Endothelial Hyperplasia (Masson's Tumor) of the Mouth - A Case Report.

We report a rare case of intravascular papillary endothelial hyperplasia (IPEH) of the oral mucosa. This neoplasm, known as Masson's tumor, is an unusual vascular lesion of proliferating endothelial cells. It is usually confined to the lumen of preexisting vessels or vascular malformations. The principal significance of IPEH is its microscopic resemblance to angiosarcoma and possible misdiagnosis as such. Achieving a correct diagnosis is essential to avoid subjecting a patient to unnecessarily aggressive therapy. For this reason, awareness of this lesion is very important for dermatologists and dentists. In this article, we discuss the clinical features, histopathological characteristics, and management of IPEH and review the pertinent literature.
