Inflammatory markers in the saliva of cerebral palsy individuals with gingivitis after periodontal treatment

Abstract The aim of this study was to evaluate the effect of periodontal treatment on the salivary cytokine levels and clinical parameters of individuals with cerebral palsy (CP) with gingivitis. A non-randomized, clinical trial was conducted in individuals diagnosed with spastic CP. Thirty-eight individuals were enrolled in the study and were categorized according to gingival index scores between 0-1 or 2-3, assigned to groups G2 or G1, respectively. Periodontal treatment comprised oral hygiene instructions, conventional mechanical treatment and 0.12% chlorhexidine applied as an adjunct. Clinical parameters and saliva samples were collected at baseline and at the 15-day follow-up visit. Bleeding on probing and periodontal screening and recording were determined. Non-stimulated saliva samples were obtained, and the salivary flow rate, the osmolality and the levels of cytokines IL-1β, IL-6, IL-8, IL-10, TNF-α and IL-12p70 were evaluated by a cytometric bead array. The Wilcoxon test, the Mann-Whitney test, Spearman correlation analysis, Poisson regression analysis and an adjusted analysis were performed (α = 0.05). The groups differed significantly in periodontal clinical parameters at baseline and at follow-up. Salivary flow rate and osmolality were similar in both groups at both timepoints. However, TNF-α and IL-1β levels were higher in G1 than in G2 at baseline. Mechanical treatment resulted in improved clinical parameters for both groups. Furthermore, mechanical treatment resulted in a significant reduction in salivary IL-1β and IL-8 levels for both groups after treatment. Periodontal treatment performed in individuals with CP and gingivitis reduces the levels of TNF-α, IL-1β, IL-6 and IL-8.

Correlation of salivary immunoglobulin A with Body Mass Index and fat percentage in overweight/obese children

Abstract Obesity is considered a risk factor for periodontal health due to the low- grade inflammation promoted by the increased adipose tissue. Objective: This study aimed to determine correlations and associations between gingival inflammation (Simplified Oral Hygiene Index, and Gingival Index), salivary immunoglobulin A (s-IgA), and salivary parameters (salivary flow and osmolality) in normal-weight and overweight/obese children. Material and Methods: Ninety-one children, aged 6 to 12 years old (8.6±1.9 years), were divided into two groups according to their body mass index (BMI), circumferences, skinfold measurements and body fat percentage: normal- weight group (NWG; n =50) and overweight/obese group (OG; n =41). A calibrated examiner performed the clinical examination using the Simplified Oral Hygiene Index, Gingival Index, and salivary collection. Data analysis included descriptive statistics and association tests ( p <0.05). Results: OG presented statistically higher s-IgA values compared with NWG, especially among the obese children ( p <0.05). Significant positive correlations between s-IgA and salivary osmolality in OG ( p <0.05), and between s-IgA and BMI values ( p <0.05) and body fat percentage ( p <0.05) were observed among all the children. Effect size varied from moderate for s-IgA values ( d =0.57) to large for BMI ( d =2.60). Conclusion: Gingival inflammation and salivary parameters were similar for NWG and OG; however, s-IgA presented higher values in OG, with correlations between BMI and body fat percentage.

Alterações fisiológicas e de erupção dentária na obesidade infantil / Physiological alteration and dental eruption in child obesity

A obesidade infantil vem crescendo e se tornando um problema mundial. Na Odontologia, em relação à obesidade infantil, já foram realizados trabalhos tentando mostrar alguma correlação entre doença cárie e doença periodontal com resultados controversos. Em relação à obesidade infantil e à erupção dentária, alguns trabalhos demostraram evidências de interação, que se apresenta precoce nesses casos, sendo importante observar os trabalhos que avaliam tais correlações. O objetivo desta revisão é associar as relações fisiológi¬cas em crianças obesas e a erupção dentária. Existem alguns fatores que podem justificar a ocorrência dessa erupção precoce como alguns hormônios do sistema endócrino, a leptina e os hormônios sexuais em crianças que apresentam obesidade. Outro ponto é a aceleração na puberdade, concomitantemente com fechamento das epífises e crescimento de ossos longos e da face nessas crianças. A pré-disposição à inflamação crônica também pode influenciar no processo de erupção dentária em crianças obesas. Os profissionais envolvidos no atendimento integral de crianças devem avaliar informações importantes como a troca de dentes e a idade estimada para a erupção dos dentes permanentes, a fim de correlacioná-las, por exemplo, a fatores como a obesidade infantil

Child obesity has been increasing and becoming a worldwide problem. In Odontology, regarding to child obesity, studies have been done trying to show a correlation between dental caries and periodontal disease, but they have had controversial results. In relation to child obesity and dental eruption, studies ­ that should be referred to ­ have provided evidence of interaction between them, which appears at early stages in these cases. This revision aims at associating the physiological relations in obese children and dental eruption. There are some factors that can justify the occurrence of these precocious eruptions such as a few hormones from the endocrine system, leptin, and sexual hormones in obese children. Another point is the acceleration in puberty, simultaneously to the closing of the epiphysis and the growth of long bones and of these children's faces. The pre-disposition to chronic inflammation can also influence the process of dental eruption in obese children. The professionals involved in the full care of children must assess important information, such as tooth change and the estimated age for the eruption of permanent teeth, in order to correlate it to factors such as child obe¬sity, for instance
