RESUMO

The effectiveness of azithromycin combined with full-mouth scaling procedures was compared to quadrant-wise scaling combined with the same dosage of azithromycin when treating periodontitis patients over a 6-month period. In this randomized clinical trial study, thirty-four individuals diagnosed with generalized stage III and IV periodontitis underwent baseline, 3-month, and 6-month post-treatment examinations. The study population was randomly assigned to either full-mouth scaling (FMS) or quadrant-wise scaling and root planning (QSRP) in addition to their taking of systemic azithromycin (500 mg/day) for three consecutive days. Periodontal probing depth (PD), clinical attachment level (CAL), gingival index (GI), and plaque index (PI) were monitored along with the quantification of total bacterial load and red complex bacterial species (Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola) in subgingival samples by real time polymerase chain reaction. The volume of gingival crevicular fluid (GCF) was also monitored over time. The primary outcomes included improvements of PD and CAL. Data was statistically analyzed through a repeated-measures analysis of variance (ANOVA) test, multiple least significant difference (LSD) comparisons, Kruskal-Wallis, Friedman, and paired Student t-tests (p<0.05). FMS and QSRP provided similar PD, CAL, GI, PI, and GCF improvements. After treatment, the FMS group displayed lower mean values of total bacterial load and red complex bacterial species in comparison to the QSRP group. FMS and QSRP in conjunction with systemic azithromycin appeared to be an effective and reliable short-term therapeutic approach for the treatment of generalized stage III and IV periodontitis. However, FMD demonstrated superiority in regard to the 6-month antibacterial effects when compared to QSRP.

Resumo A efetividade da azitromicina combinada com a técnica de desinfecção total da boca (DTB) foi comparada a raspagem por quadrante (RQ) utilizando a mesma dosagem de azitromicina no tratamento de indivíduos com periodontite generalizada estágio III e IV, em um período de 6 meses. Trinta e quatro indivíduos foram submetidos aos exames no baseline, 3 e 6 meses pós-tratamento. A população estudada foi alocada aleatoriamente no grupo DTB ou RQ associado a três dias consecutivos de azitromicina (500 mg/dia). Profundidade de sondagem (PS), nível clínico de inserção (NIC), índice gengival (IG) e o índice de placa (IP) foram monitorados, além da quantificação da carga bacteriana total e das espécies bacterianas do complexo vermelho (Porphyromonas gingivalis, Tannerella forsythia e Treponema denticola), em amostras subgengivais, a partir da reação em cadeia da polimerase em tempo real. O volume de fluido crevicular gengival (FCG) também foi monitorado ao longo do tempo. Os resultados primários foram melhorias de PS e NIC. Os dados foram analisados estatisticamente por Análise de variância (ANOVA), comparações múltiplas de diferença menor (LSD), Kruskal-Wallis, Friedman e teste t de Student emparelhado (p<0,05). DTB e RQ forneceram melhorias em PS, NIC, IG, IP e FCG semelhantes. Após o tratamento, o grupo DTB apresentou valores médios mais baixos da carga bacteriana total e de espécies bacterianas do complexo vermelho em comparação com o grupo RQ. DTB e RQ associado a azitromicina sistêmica mostraram ser similarmente uma abordagem terapêutica de curto prazo, eficaz e confiável para o tratamento de periodontite generalizada estágio III e IV. No entanto, DTB demonstrou superioridade sobre os efeitos antibacterianos aos 6 meses em comparação com RQ.

RESUMO

OBJECTIVE: To evaluate the epidemiological and microbiological aspects of the potential association between bipolar affective disorder (BAPD) and periodontitis. METHODOLOGY: The present case-control study comprised 176 individuals with BAPD and 176 controls. All individuals underwent a complete full-mouth periodontal examination and microbiological sampling. Data on bleeding on probing, probing depth, and clinical attachment level in all present teeth were recorded. Quantification of total bacterial load and Aggregatibacter actinomycetemcomitans, Treponema denticola, and Porphyromonas gingivalis counts were performed through qPCR. Data were analyzed using univariate analysis, Spearman correlation and multivariate logistic regression. RESULTS: The prevalence of periodontitis was 39.7% among controls and 58.5% among individuals with BAPD (OR = 2.13; 95% CI 1.39-3.27). A. actinomycetemcomitans and P. gingivalis counts were significantly higher in individuals with BPAD and periodontitis. The final multivariate logistic regression revealed that periodontitis was strongly associated with the total bacterial load (OR = 1.91; 95% IC = 1.0-1.99; P < 0.001) and the depressive phase of BPAD (OR = 28.94; 95% IC = 4.44-177.27; P < 0.001). CONCLUSION: BAPD was associated with increased risk for periodontitis. Individuals with BPAD presented higher levels of A. actinomycetemcomitans and P. gingivalis, suggesting that periodontitis could be a co-morbidity frequently found in individuals with BAPD.

RESUMO

Transovarial transmission is among the reported factors able to influence environmental maintenance of dengue virus (DENV). Endemic areas with active transmission of dengue are suitable for studying transovarial transmission. Brazil is a country where dengue is endemic and where DENV-1 is the most common disease-related virus serotype. This study aimed to identify transovarial transmission of DENV-1 in Aedes aegypti larvae by reverse-transcriptase nested real-time polymerase chain reaction. Between March and October 2016, Culicidae larvae were collected using traps in 3 locations in Taubaté, São Paulo, Brazil, which has a high occurrence of dengue. The collected larvae were sacrificed in the 3rd or 4th larval stage, classified, and stored at -20 °C. The A. aegypti larvae samples (n = 910) were separated into 91 pools of 10 specimens each from which RNA was extracted, reverse transcribed into cDNA, and analyzed by nested qPCR. None of the pools tested positive for DENV-1. Due to the absence of detectable virus in the evaluated samples, we concluded that transovarial transmission may not be the primary mechanism for maintenance of DENV-1 in this particular environment.

RESUMO

OBJECTIVES: Patients with diabetes have a poor oral health-related quality of life (OHRQoL). It is not clear if this situation could be changed with effective periodontal treatment. This study examined both patients with diabetes and systemically healthy individuals to discover the impact of a gingivitis treatment protocol on OHRQoL and its relation to objective periodontal parameters. DESIGN: After ultrasonic debridement, patients were randomly assigned to an essential-oils (EO) or placebo mouthwash group. At baseline and 3 months, OHRQoL was assessed with the Oral Health and Quality of Life-United Kingdom questionnaire (OHQoL-UK) along with clinical, halitometric, microbiological and inflammatory objective parameters. The primary outcome was a change in OHQoL-UK scores. A factor analysis was performed and the impact of the extracted quality of life factor (QLF) and its interactions with diabetes, treatment, and time on the objective parameters, were tested by multiple linear regression models (p < 0.05). Chi-Square test compared questionnaire-answering profiles (p<0.05). RESULTS: Combined treatment with EO provided OHQoL improvements in both systemic conditions. Positive effect of oral health status on quality of life increased in EO groups but not in placebo groups. Question I (self-confidence) showed the greatest factorial weight, while Question A (food intake) showed the lowest factorial weight. All patients who showed OHRQoL improvements and used the EO rinse showed the lowest plaque and gingival indices and lower levels of bacteria and volatile sulfur compounds. CONCLUSIONS: OHRQoL positively changed overtime. Most effective treatment protocols would provide better improvements in OHRQoL which is related to periodontal objective measures.

RESUMO

A obesidade vem sendo considerada um dos maiores problemas de saúde pública da era moderna. A doença influencia negativamente a saúde geral do indivíduo, desencadeando ou agravando inúmeras doenças e comorbidades. Estudos sugerem que a obesidade pode influenciar a severidade e a progressão da doença periodontal, através do aumento de citocinas inflamatórias como o TNF-α, IL-6 e IL-8 secretadas pelo tecido adiposo na corrente sanguínea. Por isso, a presente revisão de literatura objetivou avaliar se a terapia não cirúrgica é eficaz no tratamento da doença periodontal em indivíduos obesos. Utilizando-se Obesity AND Periodontitis AND Periodontal Therapy como palavras chave, foram levantados artigos na base de dados Pubmed, publicados entre os anos de 2011 e 2016, na língua inglesa. A maior parte dos estudos investigou o modelo de tratamento convencional e monitorou parâmetros clínicos. Os resultados demonstraram que clinicamente os obesos respondem favoravelmente a raspagem e alisamento radicular, incluindo diminuição de profundidade de sondagem e melhora na condição gengival. Os estudos que incluíram parâmetros bioquímicos também demonstraram resultados favoráveis. Entretanto, outros parâmetros devem ser monitorados como desfechos e outras modalidades terapêuticas precisam ser testadas para que se possa avaliar melhor a real eficácia do tratamento em obesos. Considerando-se que os dados disponíveis ainda são limitados, a literatura permitiu-nos concluir que a terapia periodontal convencional é efetiva em indivíduos obesos

Obesity has been considered one of the greatest public health problems of the modern era. The disease adversely affects the overall health of the individual, triggering or worsening numerous diseases and comorbidities. Studies suggest that obesity can influence the severity and progression of periodontal disease by the increase of inflammatory cytokines such as TNF-α, IL-6 and IL-8 secreted by adipose tissue in the bloodstream. Therefore, the aim of this literature review is to assess the efficacy of non-surgical periodontal therapy in obese individuals. Using Obesity AND Periodontitis AND Periodontal Therapy as keywords, articles published between 2011 and 2016 in the English language were searched in Pubmed database. Most studies had focused on conventional treatment and monitored clinical parameters. Obese showed good clinical response to scaling and root planing, including a decrease in pocket depth and improvement in the gingival condition. Studies that included biochemical parameters also showed favorable results. However, other parameters should be monitored as outcomes and other therapeutic modalities need to be tested so that the real effectiveness of treatment in obese patients can be better evaluated. Considering the limitation of available data, the literature enabled us to conclude that periodontal therapy is effective in obese individuals
