Antibiotics prescribing habits of Brazilian general dental practitioners during periodontal treatments / Hábitos de prescrição de antibióticos de dentistas brasileiros durante tratamentos periodontais

Introdução: O tratamento periodontal envolve procedimentos que visam reduzir a carga bacteriana, envolvendo ou não o uso de antibióticos locais ou sistêmicos. Objetivo: O objetivo deste estudo foi avaliar o conhecimento dos cirurgiões-dentistas brasileiros sobre a prescrição de antibióticos durante o tratamento periodontal. Material e método: Foi disponibilizado um questionário online solicitando aplicação sistêmica de prescrição de antibióticos locais ou sistêmicos (frequência e sequência com tratamento periodontal mecânico) e em relação a diferentes doenças periodontais. A utilização de serviços de diagnóstico microbiano e dados demográficos dos voluntários também foram elucidados. Os dados foram analisados estatisticamente (Teste Binomial, p<0,05). Resultado: Trezentos e noventa e três voluntários responderam ao questionário. Vinte e três por cento do sexo masculino e 76,2% do sexo feminino. A idade média foi de 27,7 anos. A minoria (19,2%) dos voluntários relatou indicar antibióticos sistêmicos para tratamento de gengivite ou periodontite estágios I e II (antiga periodontite crônica leve e moderada). A maioria dos profissionais indica para tratar abscesso periodontal, gengivite ou periodontite ulcerativa necrosante, periodontite em imunodeficiências graves, periodontite agressiva antiga e periodontite estágios III e IV (periodontite crônica grave antiga). Raramente (2,5%) a prescrição foi sem a associação com terapia mecânica. Os exames microbiológicos como método auxiliar de diagnóstico raramente (3,1%) são solicitados por falta de informação ou custo. As respostas mais frequentes sobre o número de vezes que os profissionais relataram prescrever antibióticos sistêmicos como parte do tratamento periodontal por trimestre foram "pelo menos uma vez", seguido de "2 vezes". Conclusão: Pode-se concluir que os cirurgiões-dentistas brasileiros possuem conhecimento sobre a correta prescrição de antibióticos na terapia periodontal

Introduction: Periodontal treatment involves procedures aimed to reduce bacterial load, involving or not the use of local or systemic antibiotics. Objective: The purpose of this study was to assess Brazilian dentists' knowledge about antibiotics prescription during periodontal treatment. Material and method: An online questionnaire was available asking for systemic application of local or systemic antibiotics prescription (frequency, and sequence with mechanical periodontal treatment) and in relation to different periodontal diseases. The use of microbial diagnostic services and volunteers' demographic data were also elucidated. Data were statistically analyzed (Binomial Test, p<0.05). Result: Three hundred and ninety-three volunteers answered the questionnaire. Twenty-three percent males and 76.2% females. Average age was 27.7 years. Minority (19.2%) of the volunteers reported to indicate systemic antibiotics to treat gingivitis or periodontitis stages I and II (old slight and moderate chronic periodontitis). Majority of the professionals indicate it to treat periodontal abscess, necrotizing ulcerative gingivitis or periodontitis, periodontitis in severe immunodeficiencies, old aggressive periodontitis, and periodontitis stages III and IV (old severe chronic periodontitis). Rarely (2.5%) the prescription was without the combination with mechanical therapy. Microbiological tests as an auxiliary diagnostic method are rarely (3.1%) requested due to lack of information or cost. Most frequent answers about the number of times professionals reported prescribing systemic antibiotics as part of periodontal treatment per trimester was "at least once", followed by "2 times". Conclusion: It can be concluded that Brazilian dentists have knowledge about the correct prescription of antibiotics in periodontal therapy

Comparison of gingival inflammatory parameters and pain perception on periodontal probing - a cross sectional study, part II / Comparación de parámetros inflamatorios gingivales y percepción del dolor en el sondaje periodontal - un estudio transversal, parte II

Background: Probing of the periodontal pocket is an essential part of the diagnosis of periodontal disease and 15-77% of untreated periodontal patients experience pain during probing. Therefore, the objective of this study is to evaluate the pain perceived by patients with dental plaque-induced gingivitis and chronic periodontitis during periodontal probing and the main objective includes the evaluation of the relationship between pain perceived during periodontal probing and gingival inflammatory parameters. Material and Methods: A total of 475 participants were recruited into the study. The patients were divided into two groups: Group-A (Gingivitis Group - 275 patients) and Group-B (Chronic Periodontitis Group - 200 patients). Clinical parameters included analysis of bleeding on probing, simplified gingival index, pocket depth on probing, and clinical attachment level. Pain score was recorded using the HP VAS scale and all patients participated in the study after a detailed explanation of the study protocol. Results: A significant difference in pain perception was noted between groups, highlighting the role of the degree of inflammation in the examination of periodontal parameters. Conclusion: Within the limitations of the present study, we can conclude that pain perception is directly correlated with the degree of inflammation in periodontitis rather than plaque-induced gingivitis during periodontal probing. Therefore, some form of adjuvant topical anesthesia may be considered in order to reduce pain levels in severely inflamed patients, to encourage continued acceptance of supportive periodontal therapy.

Antecedentes: El sondaje de la bolsa periodontal es una parte esencial en el diagnóstico de la enfermedad periodontal. 15-77% de los pacientes periodontales no tratados experimentan dolor durante el sondaje. Por lo tanto, el objetivo de este estudio es evaluar el dolor percibido por pacientes con gingivitis inducida por placa dental y periodontitis crónica durante el sondaje periodontal y el objetivo principal incluye la evaluación de la relación entre el dolor percibido durante el sondaje periodontal con parámetros inflamatorios gingivales. Material y Métodos: Un total de 475 sujetos fueron reclutados en el estudio. Los sujetos se dividieron en 2 grupos: Grupo - A (Grupo de gingivitis - 275 pacientes) y Grupo - B (Grupo de periodontitis crónica - 200 pacientes). Los parámetros clínicos incluyeron el análisis del sangrado al sondaje, el índice gingival simplificado, la profundidad de la bolsa al sondaje y el nivel de inserción clínica. La puntuación del dolor se registró utilizando la escala HP VAS y todos los pacientes participaron en el estudio después de una explicación detallada del protocolo del estudio. Resultados: Se notó una diferencia significativa en la percepción del dolor en el grupo B que en el grupo A, lo que significa el papel del grado de inflamación en el examen de los parámetros periodontales. Conclusión: Dentro de las limitaciones del presente estudio, podemos concluir que la percepción del dolor se correlaciona directamente con el grado de inflamación que se observa en la periodontitis más que con la gingivitis inducida por la placa dental durante el sondaje periodontal. Por lo tanto, se puede considerar alguna forma de anestesia tópica adyuvante para reducir los niveles de dolor en pacientes gravemente inflamados para fomentar la aceptación continua de la terapia periodontal de apoyo.

Evaluation of pain perception on periodontal probing in patients with dental plaque induced gingivitis and chronic periodontitis - a cross sectional study, part I / Evaluación de la percepción del dolor al sondaje periodontal en pacientes con gingivitis inducida por placa dental y periodontitis crónica: un estudio transversal, parte I

Background: Probing of periodontal pockets is an essential part in the diagnosis of periodontal disease. Fifteen to seventy seven percent of untreated periodontal patients experience pain during probing. Hence the aim of this study is to evaluate the pain perceived by patients with gingivitis and periodontitis during periodontal probing. The goals of this study were to compare the patients' pain perception when using a conventional UNC15 probe and a manual pressure sensitive periodontal probe, and to relate the clinical features of gingivitis and periodontitis to the discomfort associated with periodontal probing. Material and Methods: A total of 475 subjects were recruited into the study. The subjects were initially divided into two groups ­ Group ­ A (Gingivitis group - 275 patients) and Group ­ B (Chronic Periodontitis group -200 patients) according to the AAP 1999 Classification. These two groups were further subdivided into two groups each (Gingivitis ­ Conventional Probe ­ GCP, Gingivitis ­ Manual Pressure Sensitive Probe ­ GMPS, Periodontitis - Conventional Probe ­ PCP, Periodontitis ­ Manual Pressure Sensitive Probe ­ PMPS) using a computer generated program of random numbers. Results: A significant difference was noted in pain perception when pressure sensitive probe was used compared to conventional UNC-15 probe. Reduced Bleeding on Probing and Pain scores were noted in Chronic periodontitis subjects with use of pressure sensitive probe, which was statistically significant (p<0.001). Conclusion: Dentistry has changed its focus towards painless dentistry. In this context, the present study presents data towards use of manual pressure sensitive probes, which offers an advantage of low cost when compared to more advanced computerized systems with reduced pain during periodontal examination. It could result in a positive attitude of the patients towards continuous supportive periodontal therapy thereby monitoring periodontal health.

Antecedentes: El sondaje de los sacos periodontales es una parte esencial en el diagnóstico de la enfermedad periodontal. Del quince al setenta y siete por ciento de los pacientes periodontales no tratados experimentan dolor durante el sondaje. De ahí que el objetivo de este estudio fué evaluar el dolor percibido por pacientes con gingivitis y periodontitis durante el sondaje periodontal. Los objetivos de este estudio fueron comparar la percepción del dolor de los pacientes al usar una sonda UNC15 convencional y una sonda periodontal sensible a la presión manual, y relacionar las características clínicas de la gingivitis y la periodontitis con la incomodidad asociada con el sondaje periodontal. Material y Métodos: Un total de 475 sujetos fueron reclutados en el estudio. Los sujetos se dividieron inicialmente en dos grupos - Grupo - A (grupo de Gingivitis - 275 pacientes) y Grupo - B (grupo de Periodontitis Crónica - 200 pacientes) de acuerdo con la Clasificación AAP 1999. Estos dos grupos se subdividieron en dos grupos cada uno (Gingivitis - Sonda convencional - GCP, Gingivitis - Sonda manual sensible a la presión - GMPS, Periodontitis - Sonda convencional - PCP, Periodontitis - Sonda manual sensible a la presión - PMPS) usando un programa generado por computadora de datos aleatorios. números. Resultados: Se notó una diferencia significativa en la percepción del dolor cuando se usó una sonda sensible a la presión en comparación con la sonda UNC-15 convencional (p<0,001). Conclusion: La odontología ha cambiado su enfoque hacia una odontología sin dolor. En este contexto, el presente estudio presenta datos hacia el uso de sondas manuales sensibles a la presión, que ofrece una ventaja de bajo costo en comparación con sistemas computarizados más avanzados con reducción del dolor durante el examen periodontal. Podría resultar en una actitud positiva de los pacientes hacia la terapia periodontal de apoyo continuo, monitoreando así la salud periodontal.

Associação entre doença periodontal e obesidade: uma revisão de literatura / Association between periodontal disease and obesity: a literature review

Objetivo: Este estudo teve o objetivo de avaliar a associação entre doença periodontal e obesidade. Métodos: Foi realizada uma busca nas bases PubMed, SciELO e Bireme, sendo incluídos estudos relevantes relacionados ao tema para síntese deste trabalho. Resultados: Foram selecionados treze artigos para serem incluídos nessa revisão, sendo um ensaio clínico, uma meta-análise, dois estudos de coorte, dois caso-controle, cinco estudos transversais e duas revisões sistemáticas. Conclusão: Existe uma plausibilidade biológica entre a obesidade e a doença periodontal, porém não há um consenso na literatura sobre essa associação. Desta forma, são necessários mais estudos prospectivos, laboratoriais, de coorte e meta-análises que avaliem tal associação entre as doenças.

Aim: This study aimed to assess the association between periodontal disease and obesity. Methods: A search was performed in the PubMed, SciELO, and Bireme databases, including relevant studies related to the theme for the synthesis of this work. Results: Thirteen articles were selected to be included in this review, one clinical trial, one meta-analysis, two cohort studies, two case-control studies, five cross-sectional studies and two systematic reviews. Conclusion: There is a biological plausibility between obesity and periodontitis, but there is no consensus in the literature about this association. Thus, further prospective, laboratory, cohort, and meta-analysis studies are needed to assess such an association between diseases.

Condições periodontais e fatores associados a profundidade de sondagem em pacientes de uma faculdade do sul do Brasil / Periodontal conditions and factors associated with the probing depth in patients from a faculty in southern Brazil

RESUMO Objetivos: Verificar os sinais clínicos periodontais e investigar a os níveis de profundidade de sondagem (PS) e fatores associados em pacientes atendidos nas Clínicas da Faculdade IMED, localizada em um município do sul do Brasil. Metodologia: Os dados foram coletados em 193 prontuários de pacientes que buscaram atendimento odontológico, no período de 2017-2018, agrupados em sociodemográficos, hábitos de higiene bucal, hábitos nocivos e doenças crônicas. Os dados clínicos foram índice de placa dental visível (IPV), índice de sangramento gengival (ISG) e PS. Após realizadas análises descritivas foi construído um modelo de Regressão linear simples e múltiplo para verificar relações entre as variáveis ao p-valor<0,05. Resultados: A maioria dos pacientes são do sexo feminino (63,2%) com média de 40,8 anos (±14,58). Os resultados descritivos de IPV, ISG e PS foram 39,11±32,28%, 21,81 ±22,43% e 2,91 ±1,09mm, respectivamente. Após os ajustes no modelo de regressão múltiplo, os portadores de diabetes e a a quantidade de cigarros fumados por dia influenciaram no nível de PS. Conclusões: Os achados desta investigação mostram um alto IPV e de SG. Apesar da média da PS ter sido baixa, portadores de diabetes e fumo foram fatores preditivos de maiores níveis de PS.

ABSTRACT: Objectives: To evaluate periodontal clinical signs and investigate the probing depth levels (PD) and associated factors in patients attending the Dental Clinics of the Faculty IMED, located in a municipality in southern Brazil. Material and Methods: The data were collected of 193 records of patients who demand dental care in the Dental Clinics for periodontal treatment, in the period 2017- 2018: sociodemographic data, oral hygiene habits, tobacco use and chronic diseases. The clinical data were: gingival bleeding index (GBI), visible plaque index (VPI) and PD. The statistical analyzed the relationship between probing depth and exposure variables, using a linear regression linear model (p-value<0.05). Results: The majority of the patients attended were female (63.2%) and 40.8 years old on average (± 14.58). The descriptive results of VPI, GBI e PD were: 39.11 ± 32.28%, 21.81 ± 22.43%, and 2.91 ± 1.09mm, respectively. After adjustments in the multiple regression model, it was observed that diabetes and quantity of cigarettes smoked had an influence on PD. Conclusions: The results obtained in this research allowed to verify a high index of VPI and GBI in the patients. The mean PD of the individuals was low, however, it was possible to verify that having diabetes and smoking a large amount of cigarettes daily were predictive factors of higher levels of PD.

Periodontal disease and its complications in cats from a shelter in the Central Region of Rio Grande do Sul / Doença periodontal e suas complicações em gatos de um abrigo na Região Central do Rio Grande do Sul

Periodontal disease is the most common infectious disease that occurs in feline patients. Although it occurs in both sexes, different age groups, and any breeds, the prevalence and severity seem much higher in cats living in animal shelters. This paper aimed to describe the clinical, radiological, cytopathological, and virological aspects of periodontal disease and its complications in cats, based on these aspects and, consequently, on the importance it brings to cat feline medicine in shelter cats. For this, nine cats with periodontal disease from a single animal shelter were evaluated. These cats demonstrated a disease characterized by halitosis, excessive salivation, and oral discomfort. Lymphadenomegaly of the mandibular and retropharyngeal lymph nodes was observed in 44.4% of the cases. Oral lesions consisted of varying degrees of gingival hyperemia, complete loss of free gingival margins, and consequently gingival retraction, dental calculus deposition, dental mobility, complete exposure of the furcation of premolars and molars, and dental roots of canines and incisors, loss of bone radiopacity due to alveolar bone resorption and tooth loss. Complications included chronic ulcerative paradental stomatitis (22.2%), faucitis (22.2%), and chronic gingivostomatitis (11.1%). None of the cats affected by periodontal disease was positive for FIV or FeLV. In 33.3% of the cases, cats were carriers of feline calicivirus, but not feline herpesvirus.(AU)

Doença periodontal é a mais comum doença infecciosa que ocorre em pacientes felinos. Embora ocorra em gatos de ambos os sexos, diferentes faixas etárias e quaisquer raças, a prevalência e a gravidade parece muito maior em gatos que vivem em abrigos para animais. Baseado nesses aspectos e, consequentemente, na importância que ela traz para a medicina felina de gatos de abrigos, o objetivo desse artigo é descrever os aspectos clínicos, radiológicos, citopatológicos e virológicos da doença periodontal e suas complicações em gatos. Para isso, nove gatos com doença periodontal oriundos de um único abrigo de animais foram avaliados. Esses gatos demonstraram uma doença caracterizada por halitose, salivação excessiva e desconforto oral. Linfadenomegalia dos linfonodos mandibulares e retrofaríngeos foi observada em 44,4% dos casos. As lesões orais consistiam de graus variados de hiperemia gengival, perda completa das margens gengivais livres e, consequentemente, retração gengival, deposição de cálculo dental, mobilidade dentária, exposição completa da furca dos pré-molares e molares e das raízes dentárias dos caninos e incisivos, perda de radiopacidade óssea devido à reabsorção de osso alveolar e perda dentária. Complicações incluíram estomatite paradental ulcerativa crônica (22,2%), faucite (22,2%) e gengivoestomatite crônica (11,1%). Nenhum dos gatos afetados pela doença periodontal foi positivo para FIV ou FeLV. Em 33,3% dos casos, os gatos eram portadores do calicivírus felino, mas não do herpesvírus felino.(AU)

Periodontal disease distribution, risk factors, and importance of primary healthcare in the clinical parameters improvement / Distribución de la enfermedad periodontal, factores de riesgo e importancia de la atención primaria en salud en la mejora de los parámetros clínicos

The objective of this study is to show the distribution of periodontal disease, risk factors, and importance of primary healthcare, for the improvement of clinical parameters. Two phases study transversal and nonrandomized trial (before - after), with educational intervention and conservative treatment, were carried out at Dental School of the Universidad Autónoma de Guerrero México, in 161 subjects who met the inclusion criteria. Oral healthcare education was carried out as well as conservative periodontal treatment, with six months follow up. Clinical measurements were performed with a Williams probe, O'Leary plaque index, calculus index and dental mobility Miller method. Periodontal disease was found on 82 % of all participants. Multinomial logistic regression analysis showed an odds ratio of 14.3 (95 % CI: 2.5, 82.1), 13.4 (95 % CI: 1.7, 103.5), 29.2 (95 % CI: 3.2, 260.9) and 68 (95 % CI: 6.6, 711.0) plaque in gingivitis, mild, moderate and severe chronic periodontitis, respectively. The longitudinal panel data analysis showed a significant effect (p <0.001) in the mean decrease of the clinical parameters after intervention, probing depth 0.4 mm (95 % CI: -0.5, -0.3), pockets depth 1.1 mm (95 % CI: -1.3, -0.9), amount of pockets 4.5 (95 % CI: -5.2, -3.7), bleeding 5.2 (95 % CI: -5.9, -4.5) and dental mobility 0.6 degrees (95 % CI: -0.7, -0.5). Primary healthcare is still the best option to improve the periodontal health in population who do not have access to specialty services. Dentists can achieve significant clinical improvement at very low cost, if they are aware of primary health care.

El objetivo del estudio fue mostrar la distribución de la enfermedad periodontal, los factores de riesgo y la importancia de la atención primaria de salud, para la mejora de los parámetros clínicos. Material y método: Estudio de dos fases transversal y no aleatorizado (antes - después), con intervención educativa y tratamiento conservador, realizado en la Facultad de Odontología de la Universidad Autónoma de Guerrero México, en 161 sujetos que cumplieron con los criterios de inclusión. Se llevó a cabo una educación sanitaria oral, así como un tratamiento periodontal conservador, con un seguimiento de seis meses. Las mediciones clínicas se realizaron con una sonda Williams, el índice de placa O'Leary, el índice de cálculo y el método Miller de movilidad dental. Resultados: se encontró enfermedad periodontal en el 82 % de todos los participantes. El análisis de regresión logística multinomial mostró un odds ratio de 14.3 (IC 95 %: 2.5, 82.1), 13.4 (IC 95 %: 1.7, 103.5), 29.2 (IC 95 %: 3.2, 260.9) y 68 (IC 95 %: 6.6, 711.0) placa en gingivitis, periodontitis crónica leve, moderada y grave, respectivamente. El análisis de datos del panel longitudinal mostró un efecto significativo (p <0.001) en la disminución media de los parámetros clínicos después de la intervención, profundidad de sondeo 0.4 mm (IC 95 %: -0.5, -0.3), profundidad de bolsillos 1.1 mm (IC 95 %: -1.3, -0.9), cantidad de bolsillos 4.5 (IC 95 %: -5.2, -3.7), hemorragia 5.2 (IC 95 %: -5.9, -4.5) y movilidad dental 0.6 grados (IC 95 %: -0.7, - 0.5). Conclusiones: la atención primaria de salud sigue siendo la mejor opción para mejorar la salud periodontal en la población que no tiene acceso a servicios especializados. Relevancia clínica: los dentistas pueden lograr una mejora clínica significativa a un costo muy bajo, si conocen la atención primaria de salud.

Gingivitis influences oral health-related quality of life in adolescents: findings from a cohort study / A gengivite influencia a qualidade de vida relacionada à saúde bucal de adolescentes: achados de um estudo de coorte

ABSTRACT: Introduction: Oral health-related quality of life (OHRQoL) is affected by different clinical conditions. The aim of this study was to evaluate the impact of gingivitis on OHRQoL in adolescents. Methodology: This cohort study consisted of a random sample of 1,134 schoolchildren enrolled during 2012, in Santa Maria, Brazil. After two years, 743 adolescents were follow-up (response rate: 65.5%). Clinical, socioeconomic and OHRQoL data were collected. OHRQoL was assessed by the short Brazilian version of the Child Perceptions Questionnaire 11-14 (CPQ11-14), and gingival bleeding through Community Periodontal Index. Gingivitis was considered with the presence of 15% or more bleeding sites. Poisson regression models were used to evaluate the association between gingivitis and overall and domain-specific CPQ11-14 scores. Prevalence of gingivitis at baseline was considered the main predictor for the OHRQoL at follow-up. Results: Gingivitis at baseline was associated with higher overall CPQ 11-14 score (RR = 1.07; 95%CI 1.01 - 1.14), and emotional well-being (RR = 1.17; 95%CI 1.04 - 1.31), independently of other oral conditions and socioeconomic variables. Conclusions: The findings indicate that gingivitis negatively impacts the adolescents' OHRQoL. Moreover, gender, maternal schooling and household income were also associated with OHRQoL.

RESUMO: Introdução: Qualidade de vida relacionada à saúde bucal (QVRSB) é afetada por diferentes condições clínicas. O objetivo deste estudo foi avaliar o impacto da gengivite na QVRSB de adolescentes. Metodologia: Este estudo de coorte consistiu em uma amostra aleatória de 1.134 escolares iniciado em 2012, na cidade de Santa Maria, Brasil. Após dois anos, 743 adolescentes foram acompanhados (taxa de resposta: 65,5%). Dados clínicos, socioeconômicos e de QVRSB foram coletados. A QVRSB foi avaliada pela versão brasileira curta do Child Perceptions Questionnaire 11-14 (CPQ11-14) e o sangramento gengival foi coletado através do Índice Periodontal Comunitário. Gengivite foi considerada com o indivíduo apresentando 15% ou mais locais de sangramento. Os modelos de regressão de Poisson foram utilizados para avaliar a associação entre gengivite e os escores total e específico do domínio do CPQ11-14. A prevalência de gengivite na primeira avaliação foi considerada o preditor principal para a QVRSB no acompanhamento. Resultados: A gengivite no baseline foi associada à maior pontuação geral do CPQ 11-14 (RR = 1,07; IC95% 1,01 - 1,14) e ao domínio de bem-estar emocional (RR = 1,17; IC95% 1,04 - 1,31), independentemente das outras condições orais e variáveis socioeconômicas. Conclusão: Os achados indicam que a gengivite impacta negativamente a QVRSB de adolescentes. Além disso, sexo, escolaridade materna e renda familiar mensal também foram associados à QVRSB.

Oral lesions and retroviruses in shelter cats / Afecções orais e retroviroses em gatos de abrigo

Oral lesions are common problems in feline medicine worldwide, and may be associated with different causes, such as infectious agents. There are only a few studies reporting the chief oral diseases and the results for retrovirus tests in shelter cats in Brazil, especially in the South region. This study aimed to identify the main inflammatory oral lesions in shelter cats and verify the test results for feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) infections. Forty-three felines from private shelters in the central region of Rio Grande do Sul state (RS) that presented clinically evident oral lesions, regardless of age, breed, sex, and neuter status, were used in this survey. Serological tests for FIV and FeLV were performed in all cats, and data regarding the rearing system were collected. Sixteen cats (37.2%) were reared in a free system, whereas 27 (62.8%) were kept under a restrict system. Of the 43 cats with oral lesions, 29 (67.44%) presented only one type of lesion, characterized as periodontitis (n=22, 51.16%), followed by gingivitis (n=6, 13.95%), and stomatitis (n=1, 2.32%). Concomitant stomatitis and periodontitis were found in the 14 remaining cats (100%). With respect to the test results for retrovirus infections, nine (20.93%) of the 43 felines were positive for FIV alone. Co-infection with both viruses was observed in seven cats (16.28%). No cat was seropositive for FeLV valone. None of the six cats that presented gingivitis was positive for FIV and FeLV; one cat with stomatitis was positive for FIV and FeLV; of the 22 cats with periodontitis, six (27.27%) were FIV positive and two (9.09%) were FIV/FeLV positive; and of the 14 cats that presented stomatitis and periodontitis, three (21.43%) were FIV positive and four (28.57%) were FIV/FeLV positive. As for diagnosis, 28 cats (65.1%) presented solely periodontal disease (PD), one cat (2.32%) had feline chronic gingivostomatitis (FCG) alone, and 14 (32.5%) had both PD and FCG. The results obtained show that the main oral lesions found in shelter cats in the central region of RS were gingivitis, stomatitis, and periodontitis. Periodontitis, in association or not with stomatitis, was the most frequently observed oral cavity lesion in FIV- and/or FeLV-positive cats. Other factors may contribute to installation of inflammatory oral diseases in shelter cats because most cats with oral cavity lesions tested negative for retrovirus infections.(AU)

As afecções orais são problemas comuns em medicina felina em diferentes locais do mundo e podem estar relacionadas a diferentes causas, como agentes infecciosos. Poucos estudos foram encontrados no Brasil sobre o levantamento das principais doenças orais e dos resultados de testes para retrovírus em gatos de abrigos, principalmente na região Sul. Diante disso, o objetivo deste artigo foi identificar as principais afecções orais inflamatórias em gatos de abrigos e verificar os resultados dos testes para o vírus da imunodeficiência felina (FIV) e o vírus da leucemia felina (FeLV). Foram incluídos 43 felinos provenientes de abrigos privados localizados na região central do Rio Grande do Sul (RS) que apresentavam lesões orais clinicamente evidentes, independente de idade, raça, gênero e estado reprodutivo. Em todos os gatos foram realizados testes sorológicos para FIV e FeLV e obtidas informações referentes ao sistema de criação. Em 16 gatos (37,2%), o sistema de criação era livre, enquanto em 27 (62,8%) era restrito. Dos 43 gatos com lesões orais, em 29 (67,44%) foi verificado somente um tipo de lesão, caracterizado como periodontite (n=22, 51,16%), seguido de gengivite (n=6, 13,95%) e estomatite (n=1, 2,32%). Lesões concomitantes de estomatite e periodontite foram encontradas nos 14 gatos (100%) restantes. Quanto aos resultados dos testes para retrovírus, nove (20,93%) dos 43 felinos testados, foram positivos somente para FIV. Em sete gatos (16,28%) foi observada coinfecção pelos dois vírus. Em nenhum gato foi observado soropositividade somente para FeLV. Dos seis gatos com gengivite, nenhum foi positivo para FIV e FeLV; um gato com estomatite foi positivo para FIV e FeLV; dos 22 gatos com periodontite, seis (27,27%) foram FIV positivos e dois (9,09%) FIV/FeLV positivos; e dos 14 com estomatite e periodontite, três (21,43%) foram FIV positivos e quatro (28,57%) FIV/FeLV positivos. Quanto ao diagnóstico, em 28 gatos (65,1%) foi observada somente doença periodontal (DP), em um (2,32%) somente gengivoestomatite crônica felina (GECF) e em 14 gatos (32,5%) DP e GECF. Diante dos resultados obtidos, pode-se concluir que as principais lesões orais encontradas em gatos de abrigos da região central do RS foram gengivite, estomatite e periodontite; a periodontite associada ou não a estomatite foi a lesão oral mais frequente nos gatos positivos para FIV e/ou FeLV. Acredita-se que outros fatores possam contribuir na instalação de doenças orais em gatos de abrigos, já que houve predomínio de gatos com resultados negativos nos testes para os retrovírus.(AU)

Impact of smoking on gingival inflammation in representative samples of three South American cities

Abstract The aim of this study was to investigate the impact of smoking on gingival inflammation in a representative sample of 1,650 adults from Santiago (Chile), Porto Alegre (Brazil), and Tucumán (Argentina). A questionnaire was administered to participants to gather demographic and behavioral characteristics, including smoking habits. The participants were clinically examined to obtain gingival index (GI), gingival bleeding index (GBI), visible plaque index (VPI), and calculus presence values. Gingival inflammation was defined as a mean GI > 0.5. Heavy smokers presented significantly lower levels of gingival inflammation, as reflected by both GI and GBI, than both light and moderate smokers, despite their having increased amounts of plaque and calculus. Being 50 years old or older [odds ratio (OR), 1.93], a VPI ≥ 30% (OR, 28.1), and self-reported diabetes (OR, 2.79) were positively associated with detection of gingival inflammation. In conclusion, the occurrence of clinically detectable gingival inflammation was lower in heavy smokers than light and moderate smokers. Older age, diabetes, and visible plaque emerged as risk indicators of gingivitis. Plaque and gingival indices are significantly associated regardless of the smoking status.

Impacto do tratamento periodontal não cirúrgico nos níveis de biomarcadores do metabolismo ósseo na saliva / Non-surgical periodontal treatment impact on biomarkers levels of bone metabolism in saliva

O objetivo foi avaliar o efeito do tratamento periodontal não cirúrgico, após 1 ano, na expressão salivar dos marcadores do metabolismo ósseo: TNF-α, SOST, PTH, OPG, OPN, OC, Leptina, IL-6, IL-1ß e FGF-23; em pacientes com periodontite crônica generalizada. Participaram deste estudo 15 pacientes com periodontite crônica generalizada (idade média 56,0  DP 9,6 anos). Quinze pacientes com gengivite (idade média 39,7  DP 4,4 anos) foram utilizados como controles. Foram utilizados os seguintes parâmetros clínicos: profundidade de bolsa à sondagem (PBS); nível de inserção clínica (NIC); índice de placa visível (IPV); índice de sangramento gengival (ISG) e índice de sangramento à sondagem (ISS). Foi realizada a coleta de saliva não estimulada (1ml) e congelada à -70°C para posterior análise. Os pacientes de ambos os grupos receberam tratamento periodontal não cirúrgico. Todos os dados foram coletados em 3 visitas no grupo com periodontite (baseline, 6 meses e 1 ano); e em 2 visitas no grupo com gengivite (baseline e 1 ano). Os biomarcadores foram mensurados por meio de um imunoensaio multiplex. No grupo com periodontite, houve redução significativa dos parâmetros % PBS ≥ 6 (p<0,001) e % NIC ≥ 5 (p<0,001), nas visitas 6 meses e 1 ano. Para os dados clínicos do grupo com gengivite, houve diminuição significativa após 1 ano para: % placa (p=0,001), % sangramento marginal (p=0,001), % sangramento sondagem (p=0,001), PBS (média pac.) (p=0,020) e NIC (média pac.) (p=0,001). Após o tratamento no grupo com periodontite, observou-se redução significativa da IL-1ß, IL-6, Leptina e TNF-α, entre a visita baseline e 6 meses (p=0,006; p=0,050; p=0,047; p= 0,014; respectivamente). Entre o baseline e 1 ano, houve diferença significante para a IL-1ß (p=0,010) e OPG (p=0,050). Já a IL-6 e OPG, mostraram uma tendência a redução após 1 ano (p=0,074; p=0,063; respectivamente). No grupo com gengivite, não foram observadas diferenças significativas entre as visitas baseline e 1 ano para todos os biomarcadores. No grupo com periodontite, na visita 1 ano, observamos correlação negativa significativa da OPG com % sangramento sondagem ( τ-b = -0,524 / p=0,006); no grupo com gengivite, na visita baseline, observamos correlação positiva significativa da IL-6 com % placa (τ-b= 0,548 / p= 0,005). Já na visita 1 ano, a Leptina passou a se correlacionar de forma mais forte com % placa (τ-b=0,624 / p=0,010) e com % sangramento marginal (τ-b=0,751 / p= 0,001). Concluindo, a terapia periodontal não cirúrgica levou a uma melhora significativa dos parâmetros clínicos periodontais associada à uma redução significante nos níveis de TNF-α, Leptina e IL-1ß; e uma tendência à redução dos biomarcadores OPG e IL-6. Após 1 ano, verificamos que os níveis dos biomarcadores do grupo com periodontite se aproximaram aos valores do grupo com gengivite, sugerindo que o tratamento periodontal foi capaz de equalizar a resposta imunológica.

The aim of this study was to evaluate the effect of non-surgical periodontal therapy, after 1 year, on the salivar expression of bone metabolism markers: TNF-α, SOST, PTH, OPG, OPN, OC, Leptin, IL-6, IL-1ß and FGF-23; in patients with generalized chronic periodontitis. Fifteen patients with generalized chronic periodontitis (mean age 56.0 ± SD 9.6 years) were included in this study. Fifteen patients with gingivitis (mean age 39.7 ± SD 4.4 years) were used as controls. Clinical evaluation parameters including probing pocket depth (PD), clinical attachment level (CAL), visible plaque index (VPI), gingival index bleeding (GI) and bleeding on probing (BOP) were used. Non-stimulated whole saliva was collected (1ml) and frozen at -70°C for further analysis. Patients from both groups received non-surgical periodontal treatment. All data were collected in 3 visits in the group with periodontitis (baseline, 6 months and 1 year); and in 2 visits in the group with gingivitis (baseline and 1 year). The biomarkers expression were evaluated through multiplex technology. In the group with periodontitis, there was a significant reduction of the parameters % PD ≥ 6 (p <0,001) and % CAL ≥ 5 (p <0,001), at 6 months and 1 year visits. For the clinical data of the group with gingivitis, there was a significant decrease after 1 year for: plaque (p=0,001), sulcus bleeding (p=0,001), bleeding on probing (p=0,001), PD (p=0,020) and CAL (p=0,001). After treatment in the group with periodontitis, a significant reduction of IL-1ß, IL-6, Leptin and TNF-α was observed between baseline and 6 months visit (p=0,006; p=0,050; p=0,047; p=0,014; respectively). Between baseline and 1 year, there was significant difference for IL-1ß (p=0,010) and OPG (p=0,050). On the other hand, IL-6 and OPG showed a tendency to decrease after 1 year (p=0,074; p=0,063; respectively). In the group with gingivitis, no significant differences were observed between the baseline visits and 1 year for all biomarkers. In the group with periodontitis, at the 1-year visit, we observed a significant negative correlation of OPG with bleeding on probing (τ-b=-0,524 / p=0,006); in the group with gingivitis, at the baseline visit, we observed a significant positive correlation of IL-6 with plaque (τ-b=0,548 / p=0,005). At the 1-year visit, Leptin correlated more strongly with plaque (τ-b=0,624 / p=0,010) and with sulcus bleeding (τ-b=0,751 / p=0,001). In conclusion, non-surgical periodontal therapy led to a significant improvement in periodontal clinical parameters associated with a significant reduction in levels of TNF-α, Leptin and IL-1ß; the OPG and IL-6 showed a tendency to reduce. After 1 year, we observed that the biomarkers levels in the group with periodontitis approximate the values of the group with gingivitis, suggesting that the periodontal treatment was able to equalize the immune response.

Prevalence of periodontitis in a population of patients on dialysis in Colombia

The aim of this study is to establish the prevalence of Chronic Periodontitis (CP) in patients with Chronic Kidney Disease (CKD) and to ascertain its relationship with several factors or indicators of micro inflammation. One hundred and thirtyfive CKD patients on dialysis treatment were included. Biochemical parameters, clinical attachment level and pocket depth were recorded according of the American Academy of Periodontology and the CDC (CDCAAP). Gingivitis and CP were recorded based on the biofilmgingival interface (BGI) periodontal diseases classification. The rate of nonresponse to the survey was 10 percent. A total 2,636 teeth in 135 patients were examined, of whom 52.5% were males. Average age was 55.7 years (SD ± 1.32); 41.4% had a smoking history; 78/135 patients were on hemodialysis and 57/135 on peritoneal dialysis; 55.5% had been on dialysis for more than three years. Prevalence of gingivitis and periodontitis was 14.8%, 95% CI (9.721.9) and 82.2%, 95% CI (74.7 ­ 87.8), respectively; according to the BGI Index. Severity of CP was: No periodontitis, 14.0% 95% CI (9.1 21.1) ; mild, 11.1% 95% CI (6.7 17.7) ; moderate, 28.8% 95% CI (21.7 37.1) ; and severe, 45.9% 95% CI (31.654.47). Peritoneal dialysis and time on dialysis > 3 years increase the chance of having periodontitis, OR 11.0 95% CI (2.253.8) and OR 7.6 95% CI (1.150.2), respectively. In view of the high prevalence of CP in this population, programs designed to ensure better periodontal and gingival care in the population on dialysis need to be established (AU)

El objetivo de este estudio fue establecer la prevalencia de Periodontitis Crónica (PC) en pacientes con enfermedad renal crónica (ERC) en diálisis y determinar la relación de su presencia con algunos indicadores de micro inflamación. Un total de 135 pacientes con ERC en terapia dialítica fueron incluidos en este estudio. Se evaluaron parámetros bioquímicos, nivel de inserción clínica (NIC) y profundidad de sondaje (PS), de acuerdo con la Asociación Americana de Periodoncia y el CDC de Atlanta (CDCAAP). También fue evaluada, la gingivitis y la PC de acuerdo con la clasificación interface biopeliculaencia (BGI). La tasa de no respuesta a la encuesta fue del 10%. Un total de 2636 dientes en 135 pacientes fueron evaluados, (52.5% hombres, edad promedio 55.7 ± 1.32), 56% con antecedente de tabaquismo. 78/135 en hemodiálisis y 57/135 en diálisis peritoneal, el 55.5 % con un tiempo en diálisis mayor a tres años. La prevalencia de gingivitis por la clasificación BGI fue del 14.8% IC 95% (9.7 21.9) y de periodontitis 82.2% IC 95% (74.7 ­ 87.8). La severidad de la PC fue: sin periodontitis 14.0% 95% IC (9.1 21.1) ; leve 11.1% 95% IC (6.7 17.7) ; moderada 28.8% 95% IC (21.7 37.1) y severa 45.9% 95% IC (31.654.47) La diálisis peritoneal y el tiempo en diálisis aumentaron la chance de tener PC: OR 11.0 95% IC (2.253.8) y OR 7.6 95% CI (1.150.2) respectiva mente. Por la alta prevalencia de PC en esta población, es necesario establecer programas para asegurar el cuidado de la salud periodontal en esta población en diálisis (AU)

Mast cell degranulation in periodontal disease from HIV-infected individuals

Aim: The objective was to compare the density and degranulation of mast cells on specimens obtained from individuals diagnosed with gingivitis or chronic periodontitis who were either non-HIV-infected or HIV-infected patients treated with highly active antiretroviral therapy (HAART). Methods: Gingival samples were taken from 16 non-HIV-infected individuals and 17 HIV-infected individuals diagnosed with gingivitis and chronic periodontitis. The samples were processed and tained with 0.3 percent o-toluidine blue. Densities (cells/mm²) and percentages of intact and degranulated mast cells were obtained. Results: No statistically significant differences were observed in the mast cell density and the percentage of degranulated mast cells between non-HIV-infected and HIV-infected individuals diagnosed with gingivitis and chronic periodontitis. Mononuclear inflammatory infiltrate was weakly correlated with the percentage of mast cells degranulated for both groups. Conclusions: There are no differences of the density and degranulation of mast cells in gingival tissue between non-HIV-infected and HIV-infected patients undergoing HAART, both groups with diagnosis of gingivitis or chronic periodontitis. This may be a result of the recovery of the immunologic system by HAART treatment.

Occurrence and predictors of gingivitis and supragingival calculus in a population of Brazilian adults

Abstract: The aim of this study was to determine the occurrence of gingivitis and calculus and their predictors in a population of adults in Brazil. A representative sample of 758 adults from 35 to 59 years of age from Porto Alegre city was examined. A structured questionnaire was applied. The Gingival Bleeding Index and the presence of calculus were measured at 4 sites/tooth. Multivariable logistic models were fitted to determine the predictors for gingival bleeding at >20% of sites. Overall, 96.5% (95% confidence interval [CI]=95.1-98.0) of individuals had ≥ 1 bleeding site. The mean percentages of sites with gingivitis and calculus were 26.1% and 44.6%, respectively. The odds of gingivitis decreased by ∼45% for individuals ≥40 years old compared to younger adults. Individuals that never performed interproximal cleaning and non-whites had an approximately two times higher chance of gingivitis. Smokers had lower chances of gingivitis than never-smokers (odds ratio=0.40; 95% CI=0.24-0.68). Higher numbers of missing teeth were associated with higher chances of gingivitis. The percentage of calculus was significantly associated with skin color, education, proximal cleaning, smoking exposure, dental visits, and tooth loss. It can be concluded that the occurrence of gingivitis and calculus was high in this Brazilian population, and it was associated with age, skin color, education, self-reported proximal cleaning, smoking, dental care, and tooth loss.

Absence of cytomegalovirus in gingivitis and chronic periodontitis in HIV-1 patients in Northern Brazil

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.
