ABSTRACT: We investigated an unusual report of localized necrotizing periodontitis coinfection in patients with mild COVID-19. Male patient, 30 years old, with previous medical history of hypovitaminosis, immunized with two doses of the Pfizer® vacci ne, attended in a dental college in northern Brazil with an acute dental emergency reporting itching, halitosis, intense gingival p ain and spontaneous bleeding, mild fever of 37.8ºC, dry cough, muscle pain and nausea. Metronidazole and chlorhexidine were prescribed to improve the necrotizing condition, to treat periodontitis scaling and root planing (SRP) were performed associated with chlo rhexidine irrigation and oral hygiene instructions, which treated the patients conditions. COVID-19 coinfections are possible, specially, oral bacterial infections which is demonstrated in this report, so correct treatment is necessary for both infections. This letter d escribes the first known occurrence of severe localized necrotizing periodontitis in the urban area of Brazil's Amazon region.

RESUMEN: Investigamos un reporte inusual de coinfección de periodontitis necrotizante localizada en pacientes con COVID-19 con síntomas leves: Paciente masculino, de 30 años, con antecedentes médicos de hipovitaminosis, inmunizado con dos dosis de la vacuna Pfizer®, atendido en una facultad de odontología en el norte Brasil, con urgencia dental aguda reportando prurito, halitosis, dolor gingival intenso y sangrado espontáneo, fiebre leve de 37,8 ºC, tos seca, mialgias y náuseas. Se prescribió metronidazol y clorhexidina para mejorar el cuadro necrosante, para tratar la periodontitis se realizó raspado y alisado radicular (SRP) asociado a irrigación con clorhexidina e instrucciones de higiene oral. Las coinfecciones por COVID- 19 son posibles, especialmente las infecciones bacterianas orales, lo cual se demuestra en este reporte, por lo que es necesario un correcto tratamiento de ambas infecciones. Esta carta describe la primera aparición conocida de periodontitis necrotizante severa de un paciente del área urbana de la región amazónica de Brasil.

Abstract INTRODUCTION The influence of cytomegalovirus (CMV) on the progression of chronic periodontitis in HIV patients is poorly investigated. METHODS ELISA was used for anti-CMV antibody IgG titer measurements and real-time polymerase chain reaction for qualitative and quantitative CMV detection. Data on the CD4 + T lymphocyte count and plasma HIV viral load were obtained from patient records. RESULTS CMV DNA was detected in samples of subgingival biofilm in only three individuals, two of them with chronic periodontitis (4%) and one with gingivitis (3.3%). CONCLUSIONS The prevalence of CMV is very low both in HIV-1 patients with gingivitis and chronic periodontitis.

Genetic disorders occur by excess or absence of chromosomal material, and the consequence of these changes is reflected in morphological and physiological changes. Autosomal disorders, which have dominant inheritance, as cleidocranial dysostosis, Craniofacial syndrome Apert, Treacher Collins and Achondroplasia have peculiar and similar characteristics. Because of their implications in the dental field, the aim of this review is to report on dysostoses, through exposure of general clinical factors and highlighting the signs in the oral cavity. Articles were selected from Lilacs, PubMed and Bireme databases, included in the year 20072014, and the keywords were: cleidocranial dysplasia, craniofacial dysostosis, mandibulofacial dysostosis, dysostosis and oral. Alterations of maxillofacial bones and craniofacial are well documented in the literature, but studies reporting an association between treatment odontologic and dysostoses are scarce. In conclusion, Oral pathological manifestations developed cause difficulty in speech, chewing, breathing, social involvement, and in a general perspective, psychological impairment and physical limitations.

Las enfermedades genéticas se producen debido a un exceso o ausencia de material cromosómico, y la consecuencia de estos cambios se refleja en los cambios morfológicos y fisiológicos. Trastornos autosómicos dominantes que tienen herencia dominante, como la disostosis cleidocraneal, el síndrome craneofacial de Apert, Treacher Collins y acondroplasia tiene características peculiares y similares. Debido a sus implicaciones en el campo de la odontología, el objetivo de esta revisión es hablar, a través de la exposición de los factores clínicos y generales, destacando los signos en la cavidad oral. Se seleccionaron los artículos de las bases de datos Lilacs, PubMed y BIREME, incluyendo los años 2007-2014, y las palabras clave fueron: displasia cleidocraneal, craneofacial mandibulofacial disostosis, disostosis y oral. Los cambios de huesos maxilofaciales y craneofaciales están bien documentados en la literatura, pero los estudios que informaron una asociación entre el tratamiento dental y disostosis son escasos. En conclusion, las manifestaciones orales son causas de dificultades del habla, masticación, respiración y la participación social.
