ABSTRACT

BACKGROUND: Complex network of pro and anti-inflammatory cytokines are known to act in inflamed periodontal tissue. This study explores the distribution of interleukin (IL)-4 (+33 C/T) and IL-17F (7383A/G, 7488A/G) gene polymorphism in chronic and aggressive periodontitis subjects of Dravidian ethnicity. MATERIALS AND METHODS: This case control study consisted of 124 periodontitis individuals comprising of 63 chronic and 61 aggressive periodontitis subjects as cases, and control group consisted of 101 healthy subjects. All subjects were genotyped for IL-4 + 33C/T, IL-17F 7383A/G, 7488A/G by polymerase chain reaction amplification followed by TaqMan assay for IL-4 + 33C/T, restriction enzyme digestion and gel electrophoresis for IL-17F 7383A/G and sequencing for IL-17F 7488A/G. RESULTS: IL-4 + 33C/T was significantly associated with periodontitis (P < 0.05) at both allelic and genotypic level. In subgroup analysis also significant difference (P < 0.05) in allelic distribution between aggressive periodontitis and control group for loci IL-4 + 33C/T was noted. However, there was a lack of association between IL-17F 7383A/G and IL-17F 7488A/G with periodontitis and its sub-groups at both allelic and genotypic levels. CONCLUSIONS: In Malayalam speaking Dravidian population IL-4 + 33C/T loci appears to be an important risk factor for periodontal disease with a leaning towards aggressive periodontitis. The association between IL-17F at 7383A/G and 7488A/G loci with either chronic or an aggressive periodontitis could not be ascertained.

ABSTRACT

Ectrodactyly-ectodermal dysplasia-cleft (EEC) syndrome is an autosomal dominant disorder characterized by the triad of ectrodactyly, ectodermal dysplasia, and facial clefting. Even though literature has documented the association of various genetic disorders with aggressive periodontitis, the periodontal manifestations in patients with EEC syndrome have never been addressed. This case report presents the periodontal status of three patients in a family with EEC syndrome. The presence of generalized aggressive periodontitis was noticed in these patients. EEC syndrome could be a new addition to the group of genetic disorders associated with aggressive periodontitis.

ABSTRACT

This study aimed to assess the prevalence of aggressive periodontitis (AgP), and to investigate the association between demographic, socioeconomic and behavioral risk indicators with AgP in an untreated and isolated young population in Southeastern Brazil. For this cross-sectional survey, 134 subjects aged 12-29 years were selected by a census. Of those eligible, 101 subjects received a full-mouth clinical examination, and were interviewed using a structured written questionnaire. Cases were defined as individuals with 4 or more teeth with attachment loss > 4 mm or > 5 mm in the age groups 12-19 and 20-29, respectively. Overall, 9.9 percent of the subjects presented AgP (10.3 percent of the 12-19-year-olds and 9.7 percent of the 20-29-year-olds). The only risk indicator significantly associated with AgP in this isolated population was a high proportion of sites (> 30 percent) presenting supragingival calculus [OR = 23.2]. Having experienced an urgency dental treatment was a protective factor for AgP [OR = 0.1]. The authors concluded that this isolated and untreated population from Brazil presented a high prevalence of AgP. Local plaque-retaining factors played a major role in the prevalence of AgP in this isolated population, and should be included in further studies evaluating this destructive periodontal disease form.

ABSTRACT

O objetivo do presente estudo foi avaliar se a severidade da má oclusão está relacionada com as condições de saúde bucal, levando-se em consideração o Índice de Necessidade do para Tratamento Ortodôntico (IOTN). A amostra foi composta de 1182 escolares com 12 anos de idade que nunca tinham sido submetidos a nenhum tratamento ortodôntico, examinados em um levantamento epidemiológico em 50 escolas aleatoriamente selecionadas, da rede Municipal do Rio de Janeiro. A condição periodontal foi aferida através do Índice Comunitário de Necessidade de Tratamento Periodontal (ICNTP) e a condição dental pelo índice CPO-D. O CPO-D dos indivíduos não variou significativamente entre os patamares de severidade de má oclusão, avaliados pelo Componente de Saúde Dental (DHC) de IOTN (qui quadrado de Pearson, p=0,500). A severidade estética da má oclusão apresentou relação com o índice CPO-D, levando-se em consideração o Componente Estético (AC) de IOTN. Os casos com CPO-D mais elevados (>3) apresentaram, segundo o examinador, casos mais frequentes situados nos patamares de maior necessidade de tratamento ortodôntico levando-se em consideração a estética do sorriso (p<0,05). Os resultados do índice ICNTP revelaram que os casos com maior necessidade de tratamento periodontal tinham severidade de má oclusão semelhantes aos demais (p<0,05), quando do DHC foi avaliado. No entanto, os indivíduos com maior prejuízo estético, determinado pelo AC-Avaliador, apresentaram mais casos com bolsas de 4-5mm

ABSTRACT

En este estudio de tipo descriptivo y diseño no experimental se buscó identificar la tendencia de aparición de la enfermedad periodontal (gingivitis, alteraciones mucogingivales y periodontitis juvenil) en jóvenes con edades entre 13 y 17 años de edad. Se examinó una población de 117 jóvenes, 87 hombres y 30 mujeres que no tuvieran compromiso sistémico ni tratamiento con aparatología ortodóntica fija actual. La evaluación periodontal fue realizada por un solo examinador y con sondas periodontales milimitradas y radiografías periapicales a todos los dientes presentes. Se analizaron margen, bolsa, hemorragia y línea mucogingival. Los resultados obtenidos fueron analizados por medio de estadística descriptiva. Se concluyó que el 100 por ciento de la muestra presentó algún tipo de enfermedad periodontal

ABSTRACT

En este estudio descriptivo de diseño no experimental se estudiaron las historias clínicas de 107 pacientes que fueron atendidos en el posgrado de periodoncia de la Pontificia Universidad Javeriana, desde agosto de 1997 hasta diciembre de 1998. Se realizó un muestreo intencional, observando las historias clínicas de dichos pacientes y se recolectó información en un formato previamente determinado el cual incluía edadm género, tabaquismo y demás datos personales del paciente. Se analizaron los resultados por medio de estadística descriptiva, según la cual se encontró que 7 pacientes tenían diagnóstico de periodontitis rápida progresiva (6.5 por ciento, 5 de los cuales eran hombres y 2 mujeres. El rango de edad de estos pacientes estuvo entre los 31 y los 42 años. Por último, no se encontró relación entre el tabaquismo y la aparición de periodontitis rápida progresiva

ABSTRACT

Periodontite juvenil localizada PJL e sua forte associaçäo com o actinobacillus actinomycetemcomitans (Aa) tem sido usada para evidenciar a teoria da placa específica na doença periodontal. A prevalência da doença varia de 0,1 por cento a 3 por cento na maior parte dos estudos. Esta baixa prevalência gera a necessidade de examinar um grande número de indivíduos, a fim de conseguir uma amostragem significativa para análise. Contudo há necessidade de um método de exame näo dispendioso, fácil de aplicar, válido e confiável. O objetivo deste trabalho é registrar a sensibilidade e especificidade de um novo método de exame, usando cunha de madeira pra medir a profundidade dos sulcos
