ABSTRACT

Context: Interleukin?33 and its receptor soluble suppression of tumorigenicity 2 (sST2) play an important role in inflammation and its role in periodontal disease is yet unclear. The role of both IL?33 and sST2 together in periodontal disease as biomarkers has never been studied. Aim: To assess the levels of IL?33 and sST2 in serum samples of patients with periodontitis and healthy subjects. Methods: A total of 71 subjects (30 healthy subjects and 41 patients with periodontal disease) were included in the cross?sectional study. Community Periodontal Index (CPI) was used to assess periodontal health by utilizing a mouth mirror and a CPI probe. Venous blood was collected and serum was separated. Serum levels of IL?33 and sST2 were determined by the enzyme?linked immunosorbent assay (ELISA) assay. Statistical Analysis: Graph Pad Prism 5 was used for statistical analysis. Mann Whitney test was applied to compare the two groups. Results: The level of IL?33 was not found to be elevated among healthy subjects and sST2 was found elevated among patients with periodontal disease. The serum concentration of IL?33 was found at 472 ± 114 pg/ml and 282 ± 77 pg/ml among healthy subjects and patients with periodontal disease respectively. Significantly higher values of sST2 at 28 ± 2 ng/ml were found among periodontal patients as compared to healthy subjects with values of 18 ± 1 ng/ml. No significant differences were noted between mild to moderate and severe periodontitis for IL?33 and sST2 between the two groups. Conclusion: This study shows alteration in serum levels of IL?33 and sST2 in periodontitis patients. IL?33 and sST2 may be potential inflammatory markers of periodontitis. Further studies are required on a large sample size for better understanding. This pilot study is the first to assess the serum levels of both IL?33 and sST2 together among patients with and without periodontal disease.

ABSTRACT

Objetivo: Este estudo teve por objetivo analisar a relação entre o polimorfismo c.-889 C> T no gene IL1A e periodontite em usuários do Sistema Único de Saúde de Vitória da Conquista, Bahia - Brasil.Material e Métodos: Duzentos e cinquenta e nove indivíduos foram classificados quanto ao diagnóstico de periodontite em casos e controles. O DNA genômico foi extraído a partir de células epiteliais bucais. A genotipagem foi realizada por PCR-RFLP, seguida pela eletroforese em gel de agarose. Os dados foram analisados por meio dos testes de Qui-quadrado, exato de Fisher e Hosmer-Lemeshow. Resultados: Entre os indivíduos analisados, a periodontite mostrou-se significativamente associada ao menor grau de escolaridade (p = 0,024) e às variáveis clínicas sangramento gengival (p = 0,019) e mobilidade dentária (p = 0,001). Dentre os pacientes do grupo caso, a maioria (72,88%) apresentou a forma generalizada da periodontite. As frequências genotípicas para o polimorfismo IL1Ac. 889-C> T entre os grupos caso e controle não diferiram significativamente (χ2 = 1.6983; p = 0,428). Conclusão: Nossos achados indicam a ausência de associação entre a periodontite e o polimorfismo no gene IL1A c -889 C> T na amostra avaliada. Descritores: Periodontite. Polimorfismo genético. Interleucina-1.


Aim: This study aimed to analyze the relationship between the polymorphism c.-889 C>T in the IL1A gene and periodontitis in subjects from Vitória da Conquista, Bahia, Brazil. Methods: Two hundred fifty-nine individuals were classified according to periodontitis diagnoses in cases and controls. Genomic DNA was extracted from buccal epithelial cells. Genotyping was performed by PCR-RFLP, followed by agarose gel electrophoresis. Data were analyzed using Chi-square, Fisher's exact and Hosmer-Lemeshow tests. Results: In the individuals evaluated in this study, periodontitis was significantly associated with a low educational level (p = 0.024) and clinical variables, such as gingival bleeding (p = 0.019) and tooth mobility (p = 0.001). Among patients in the case group, the majority (72.88%) had a generalized form of periodontitis. The genotypic frequencies for IL1A c.­889 C>T between the case and control groups did not significantly differ (χ2 = 1.6983; p = 0.428). Conclusion: This study's findings indicate the lack of association between periodontitis and the IL1A c -889 C>T gene polymorphism

ABSTRACT

Introdução: a infecção da polpa e dos tecidos periapicais tem a sua etiologia discutida há anos. A periodontite apical é caracterizada por ser de origem polimicrobiana, sendo o Enterococcus faecalis o microorganismo mais comumente encontrado. Em situações clínicas, o objetivo do tratamento endodôntico é eliminar micro-organismos do sistema de canais radiculares. As medicações intracanal são um importante passo no tratamento e devem ser efetivas frente aos micro-organismos que resistem ao preparo do canal radicular. Dentre as medicações empregadas, o hidróxido de cálcio é utilizado rotineiramente como medicação intracanal. Sua ação se deve ao fato de estabelecer um pH altamente alcalino dentro do canal radicular, 12,5 aproximadamente, no qual a maioria dos microorganismos não consegue sobreviver. Objetivo: realizar uma revisão de literatura sobre a relação do Enterococcus faecalis no insucesso endodôntico e a efetividade do hidróxido de cálcio nesta situação clínica. Conclusão: a ação do hidróxido de cálcio frente ao Enterococcus faecalis é limitada.


Introduction: Pulp and periapical tissue infection etiology has been discussed for many years. Apical periodontitis is characterized by multimicrobial flora origin, in which Enterococcus faecalis is the microorganism more frequently found. In clinical situations, the aim of endodontic treatment is to remove microorganisms of the system of root canals. Intra canal medications are an important step in the treatment and they must be effective in microorganisms that resist the preparation of the root canal. Among all used medications, the calcium hydroxide is frequently used. It acts establishing a highly alkaline pH inside the root canal, 12.5 approximately, in which most of the microorganisms do not manage to survive.Aim: to make a review of the literature about the relationship on the Enterococcus faecalis on endodontic failure and calcium hydroxide effectiveness in this clinical situation. Conclusion: Calcium hydroxide has limited action against Enterococcus faecalis.

ABSTRACT

A periodontite agressiva é caracterizada como doença de baixa prevalência e de rápida progressão,acometendo principalmente jovens e adultos sistemicamente sadios. O tecido gengival pode apresentarcoloração e textura normais. Observa-se a ocorrência de perda de inserção severa, com formação debolsas periodontais profundas (superiores a 5 mm) e destruição óssea localizada em incisivos e primeirosmolares ou ainda mais generalizada, envolvendo um maior número de dentes. Não há correlação comacúmulo de placa e cálculo. As características radiográficas são bastante distintas, com perda óssea angularna região de incisivos e primeiros molares, geralmente bilateral e simétrica. A mobilidade com consequentemigração dentária é comum e representa um fator de grande desconforto estético para os pacientes; quandodeixada ao curso natural da doença, pode resultar em perdas dentárias. O objetivo deste trabalho é revisaras principais características clínico-patológicas da periodontite agressiva, além abordar as medidas terapêuticas.


Aggressive periodontitis is a disease of low prevalence and rapid progression that occurs primarily inhealthy young and adult people. The gingival tissues may present normal characteristics. The occurrenceof severe attachment loss is observed, associated with deep pockets (up to 5 mm) and also bone destructionin incisive and first molars or even involving a large number of teeth. The attachment loss is notproportional to the presence of plaque and calculus. Radiographic characteristics are singular andpresent bilateral and symmetric bone loss in the incisive and first molars areas. Mobility with consequentdental migration is common and may cause aesthetic dissatisfaction among patients. If not treated, thenatural course of the disease may lead to high tooth mortality. The aim of this sudy is to review theclinical-pathological characteristics of aggressive periodontitis and its therapeutic approach.
