ABSTRACT

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.

ABSTRACT

Introdução: Nos últimos anos, um número crescente de estudos sugere a participação dos herpesvírus na doença periodontal. Objetivo: Este trabalho investiga a relação entre a presença do herpesvírus Epstein-Barr (EBV) e a infecção periodontal em pacientes com periodontite crônica. Metodologia: Foram coletadas amostras de biofilme subgengival de sítios com profundidades de sondagem de 4 a 6 mm e > 7 mm, de 28 pacientes com periodontite crônica. Como controles, foram incluídos 16 indivíduos, sistemicamente saudáveis e sem doença periodontal. Adicionalmente, parâmetros clínicos de profundidade de sondagem (PS), nível clínico de inserção (NCI) e índice de sangramento à sondagem (SS) foram registrados. Resultado: Os resultados demonstraram médias de 2,7 mm PS, 1,7 mm NCI e 0,3% dos sítios apresentaram SS. A investigação do EBV no biofilme subgengival dos grupos foi realizada por meio da reação em cadeia da polimerase com primer espécie-específico. Os resultados da análise viral indicaram ausência de EBV em todas as amostras subgengivais analisadas. Conclusão: A partir destes resultados, não foi encontrada relação entre a presença do herpesvírus Epstein-Barr e a periodontite crônica.


Introduction: In recent years, a growing number of studies have suggested the participation of the herpes virus in periodontal disease. Objective: this study investigates the relationship between the presence of the Epstein-Barr herpes virus and periodontal infection in patients with chronic periodontitis. Methodology: subgingival biofilm samples were collected of subgingival sites with probing depths of 4 mm to 6 mm, and > 7 of 28 patients with chronic periodontitis. The control group consisted of 16 healthy subjects without clinical evidence of chronic periodontitis. Additionally, clinical parameters of probing depth, attachment level and Bleeding index were recorded. Result: the results showed averages of 2 mm probing depth, 1, 7 mm attachment level and 0.3 % bleeding on probing. Investigation of the herpes virus in the subgingival biofilm of the groups was performed using polymerase chain reaction with species-specific primer. Results of viral analysis indicated the absence of EBV in all subgingival samples analyzed. Conclusion: these results found no relationship between the presence of the Epstein-Barr herpes virus and chronic periodontitis.

ABSTRACT

Revisar a literatura e relatar um caso clínico incomum de granuloma piogênico emlábio inferior. Relato de caso: paciente do gênero feminino de 53 anos de idade, com lesão emlábio inferior, há cerca de sete anos, apresentou características clínicas que induziram aoincorreto diagnóstico de hemangioma. Os achados histopatológicos exibiram tecidogranulomatoso com intensa proliferação vascular. A lesão foi removida e a paciente apresentaseem proservação clínica. Considerações finais: apesar das características clínicas dessa lesãonão serem determinantes, é importante relatar a diferença entre cada caso, sendo que apenascom o exame histopatológico podem-se ter diagnósticos mais precisos


To review the literature and report an unusual case of Pyogenic Ggranuloma onlower lip. Case report: female patient of 53 years of age, with lesions on the lower lip aboutseven years, had clinical features that led to an incorrect diagnosis of hemangioma. Thehistopathological findings showed granulomatous tissue with intense vascular proliferation. Thelesion was removed and the patient comes in clinic attend. Final considerations: although theclinical features of this lesion are not determinative, it is important to report the differencebetween each case and only with histological examination can be accurate diagnosis.
