ABSTRACT

Introdução: os dentifrícios antiplaca e anticálculo contêm, em sua composição, agentes específicos para o controle e a redução do biofilme dentário, como o citrato de zinco, o óxido de zinco e o pirofosfato tetrassódico, dentre outros. Objetivo: avaliar in vitroa ação de dentifrícios antiplaca e anticálculo na variação da massa e da rugosidade superficial do esmalte bovino submetido à escovação simulada por 6 e 12 meses.Metodologia: 40 corpos de prova (CP) foram randomizados e divididos aleatoriamente em 4 grupos (n=10): grupo controle (GC- água) e 3 grupos teste (GT1 ­ Colgate-Total® 12 Clean Mint, GT2 ­ Colgate-Total® 12 Anti-Tártaro, GT3 ­ Prevent® Antiplaca). Os CP foram submetidos à escovação simulada por 6 e 12 mesese as avaliações da massa e da rugosidade foram realizadas após cada período de escovação. Resultados: a análise da variação da massa demonstrou que não houve diferença significativa entre os grupos e os tempos. A avaliação da rugosidade demonstrou que, após 12 meses de escovação, o GT1 apresentou aumento significativo da rugosidade, quando comparado aos grupos controle e testes, enquanto os grupos GT2 e GT3 apresentaram comportamento semelhante após um ano de escovação, promovendo o polimento superficial do esmalte bovino. Conclusão: a escovação com os dentifrícios antiplaca ou anticálculo não promoveu perda significativa da massa no esmalte bovino e promoveu seu polimento.


Introduction: Antiplaque and anticalculus dentifrices contain in their composition specific agents for the control and reduction of dental biofilm, such as zinc citrate, zinc oxide, tetrasodium pyrophosphate, among others. Objective: To evaluate in vitro the action of antiplaque and anticalculus dentifrices on the variation of mass and surface roughness of bovine enamel submitted to simulated brushing for 6 and 12 months. Metodology: 40 specimens (PB) were randomized and randomly divided into 4 groups (n=10): control group (GC ­ water) and 3 test groups (GT1 ­ Colgate-Total® 12 Clean Mint, GT2 ­ Colgate-Total® 12 Anti-Tartar, and GT3 ­ Prevent®Antiplaque). The PB were submitted to simulated brushing for 6 and 12 months and the mass and roughness evaluations were performed after each brushing period. Results: The analysis of mass variation showed that there was no significant difference between groups and times. The roughness evaluation showed that after 12 months of brushing, GT1 showed a significant increase in roughness when compared to the control and test groups, while the GT2 and GT3 groups showed similar behavior after one year of brushing, promoting the surface polishing of bovine enamel. Conclusion: Brushing with antiplaque or anticalculus dentifrices did not promote significant mass loss in bovine enamel and promoted its polishing.

ABSTRACT

Afecções da cavidade oral como o cálculo dentário (CD) e a doença periodontal (DP) são frequentes na clínica de cães e têm grande impacto na saúde e qualidade de vida dos pacientes acometidos. No entanto, a adoção de medidas preventivas ainda é difícil, uma vez que a frequência das doenças da cavidade oral em cães ainda é pouco compreendida no Brasil. O objetivo deste estudo foi avaliar características demográficas e nosológicas, como os hábitos alimentares e de manejo de escovação, dos distúrbios da cavidade oral de 198 cães atendidos no período compreendido entre 2013 e 2019, em um serviço de odontologia veterinária, na cidade do Rio de Janeiro. A maioria dos cães atendidos não tinha raça definida. Entre os de raça pura, Yorkshire Terrie foi a mais prevalente, não havendo distinção significativa entre o gênero, em todos os casos. Quanto à idade, observou-se uma predominância de animais de meia idade a idosos, com faixa etária acima dos sete anos. Dentre as afecções mais prevalentes, o destaque se deve ao cálculo dentário e à doença periodontal, seguidos por gengivite e halitose. Quanto aos hábitos dos tutores, notou-se baixa adesão à realização de escovação rotineira, e um alto percentual no fornecimento de petiscos. Avaliando-se os resultados e relacionando-os aos hábitos alimentares dos pacientes, surge a hipótese de que a alimentação à base de ração comercial, de alguma forma possa contribuir para evolução do cálculo dentário, necessitando estudos com maior amostragem para elucidação.


Diseases of the oral cavity, such as Dental Calculus (DC) and Periodontal Disease (PD), are frequent in the dog clinic and have a great impact on the health and quality of life of affected patients. However, the adoption of preventive measures is still difficult, since the epidemiology of diseases of the oral cavity is still poorly understood in Brazil. The aim of this study was to evaluate demographic and nosological aspects ­ such as feeding and brushing habits ­ of disorders of the oral cavity of 198 dogs treated in the period between 2013 and 2019, in a veterinary dentistry service, in the city of Rio de Janeiro. The most prevalent breeds were mixed breed dogs, followed by Yorkshire Terries, with no significant distinction between the gender. As for age, there was a predominance of animals from middle age to the elderly, with ages above seven years old. Among the most prevalent conditions, the highlight is due to dental calculus and periodontal disease followed by gingivitis and halitosis. Regarding the tutors' habits, there was a low level of routine brushing, and a high percentage in the supply of snacks. Evaluating the results and relating them to the eating habits of the patients, the hypothesis that comercial dog food feeding may somehow contribute to dental calculus evolution, urging studies with bigger samples for a deeper investigation.

ABSTRACT

Introdução: Os distúrbios alimentares são transtornos psiquiátricos graves, com altos níveis de mortalidade, incapacidade e morbidade física e psicológica; o que provoca redução na qualidade de vida. Objetivo: O presente trabalho teve como objetivos realizar uma revisão sistemática com base na análise de publicações nacionais e internacionais presentes na literatura científica sobre a ocorrência de manifestações bucais em pacientes com anorexia e bulimia nervosa; comparar a ocorrência de cárie, erosão dentária e o perfil bioquímico salivar de mulheres com e sem transtornos alimentares; além de relatar a condição de saúde bucal de uma paciente com anorexia nervosa internada em um hospital de psiquiatria pertencente à Faculdade de Medicina de Marília (FAMEMA), São Paulo, Brasil. Metodologia: A tese foi dividida em três partes. No primeiro momento da pesquisa, realizou-se vasto levantamento bibliográfico para a elaboração do primeiro capítulo, que consistiu em uma revisão sistemática sobre o assunto. O segundo capítulo foi composto por um estudo observacional do tipo casocontrole. Realizou-se a coleta de dados com os pacientes diagnosticados com bulimia e anorexia nervosa e que estavam sob tratamento no ambulatório. O grupo controle foi composto por acompanhantes dos doentes, que possuíam características similares. O terceiro capítulo foi composto por um caso clínico de uma paciente que estava hospitalizada com anorexia nervosa no Hospital das Clínicas da FAMEMA (Unidade I), onde foi realizada toda a descrição de suas condições de saúde bucal. Resultados: No capítulo 1, foi obtido um número final de seis trabalhos, onde todos respondiam a questão sobre quais manifestações bucais são encontradas em pacientes com anorexia e bulimia nervosa, e apresentavam validade e poder em sua estrutura metodológica e resultados. No segundo capítulo, podemos observar que, o grupo das pacientes com anorexia e bulimia nervosa apresenta maiores índices de cárie e erosão dentária, assim como alterações nos parâmetros salivares, em especial o fluxo salivar e os marcadores bioquímicos fósforo, cálcio, FRAP e ácido úrico; quando comparados ao grupo controle. E por fim, na terceira parte da presente tese, observamos que a paciente apresentava 11 dentes atacados pela cárie dentária. No exame periodontal, todos os dentes sondados apresentaram sangramento, além de cálculo nos incisivos inferiores e molares superiores pela face lingual; e o fluxo salivar da paciente encontrava-se extremamente reduzido. Quanto aos parâmetros salivares, o valor encontrado para o cálcio e fósforo estavam aumentados, 13,36mg/dL e 6,31mg/dL, respectivamente. Conclusão: Dessa forma, conclui-se que pacientes diagnosticados com anorexia e bulimia nervosa normalmente apresentam lesões cariosas e erosivas nos dentes e gengivas, além de alterações nos parâmetros bioquímicos salivares(AU)


Introduction: Eating disorders are serious psychiatric disorders, with high levels of mortality, disability and physical and psychological morbidity; which causes a reduction in quality of life. Objective: The present study aimed to carry out a systematic review based on the analysis of national and international publications present in the scientific literature on the occurrence of oral manifestations in patients with anorexia and bulimia nervosa; to compare the occurrence of caries, dental erosion and the biochemical salivary profile of women with and without eating disorders; in addition to reporting the oral health condition of a patient with anorexia nervosa admitted to a psychiatric hospital belonging to the Faculty of Medicine of Marília (FAMEMA), São Paulo, Brazil. Methodology: The thesis was divided into three parts. In the first moment of the research, a vast bibliographic survey was carried out for the elaboration of the first chapter, which consisted of a systematic review on the subject. The second chapter consisted of an observational case-control study. Data collection was performed with patients diagnosed with bulimia and anorexia nervosa and who were under treatment at the outpatient clinic. The control group was composed of patients' companions, who had similar characteristics. The third chapter consisted of a clinical case of a patient who was hospitalized with anorexia nervosa at Hospital das Clínicas da FAMEMA (Unit I), where the entire description of her oral health conditions was carried out. Results: In chapter 1, a final number of six studies was obtained, in which all answered the question about which oral manifestations are found in patients with anorexia and bulimia nervosa, and presented validity and power in their methodological structure and results. In the second chapter, we can see that the group of patients with anorexia and bulimia nervosa has higher rates of caries and dental erosion, as well as changes in salivary parameters, especially the salivary flow and the biochemical markers phosphorus, calcium, FRAP and uric acid ; when compared to the control group. Finally, in the third part of this thesis, we observed that the patient had 11 teeth attacked by dental caries. In the periodontal examination, all probed teeth showed bleeding, in addition to calculus in the lower incisors and upper molars through the lingual surface; and the patient's salivary flow was extremely reduced. As for salivary parameters, the values found for calcium and phosphorus were increased, 13.36mg/dL and 6.31mg/dL, respectively. Conclusion: Thus, it is concluded that patients diagnosed with anorexia and bulimia nervosa usually have carious and erosive lesions on the teeth and gums, in addition to changes in the salivary biochemical parameters(AU)

ABSTRACT

OBJECTIVES: This study aimed to investigate factors related to the periodontal health of 12-year-old children.METHODS: In 2015, the Korean Children's Oral Health Survey from the Ministry of Health & Social Welfare conducted a nationwide representative sample comprised of 23,702 12-year-old children. The calibration-trained dentists examined the gingivitis and dental calculus of the children taking into consideration of the Löe and Silness gingival index to diagnose gingivitis with a modified gingivitis scale. We used questionnaires to collect data from the children on dental treatments, the experience of dental pain and gingival bleeding, self-perceived oral health, and oral health behaviors. Data were analyzed using a complex samples Chi-square test, general linear model, and logistic regression. Significance was determined at P < 0.05.RESULTS: The prevalence of gingivitis was higher among males (OR 1.57), among children with poor perception (OR 1.19), dental calculus (OR 3.68), or gingival bleeding experience (OR 2.00), and among children not using dental floss (OR 1.69) or tongue cleaner (OR 1.90). The prevalence of dental calculus was higher among children with gingivitis (OR 3.82) and among children who had not visited a dental clinic in the preceding year (OR 1.31). However, dental calculus was lower among children with a higher frequency of daily toothbrushing (OR 0.75), intake of cariogenic foods (OR 0.90), or a higher DMFT index (OR 0.91).CONCLUSIONS: Children with dental calculus and gingival bleeding who did not visit a dental clinic in the preceding year also had a higher prevalence of gingivitis and dental calculus. The prevalence of children's dental calculus was lower among children with a high frequency of daily toothbrushing.

ABSTRACT

The purpose of this study was to develop effective dental hygiene chews for cats based on the anatomical features of the dentition and patterns of chewing motion. All cats were volunteered for dental prophylaxis followed by dental impressions using yellow stone and alginate under general anesthesia. Twenty parameters related to dentition were defined in order to compare dental impressions using digital caliper. For the chewing motion study, patterns of chewing motion were identified based on recordings made with a digital camera. Ten cats (4 domestic shorthairs, 2 Russian blues, 1 American shorthair, 1 Persian, 1 Turkish Angora, and 1 Devon Rex) were recruited for the study. The parameters related to teeth and oral size were similar among the studied cats. Chewing motion can be described as more of a guillotine-like motion rather than a crushing motion, with cats chewing 3–7 times before swallowing. The chewing pattern of cats involves shearing for a short period of time followed by immediate swallowing. Therefore, the overall size of the dental hygiene chew could be determined based on the measurement of the oral size for inducing chewing. The surface details of the dental hygiene chew could be designed for prevention and removal of dental calculus and plaque in cats considering the anatomical teeth parameters. Dental hygiene chews customized for cats considering the different anatomical features of their teeth might be effective for oral care.

ABSTRACT

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.

ABSTRACT

La alveólisis es una condición poco frecuente y asintomática. Se produce cuando la raíz del diente primario se vuelve susceptible a la presencia de placa bacteriana y a la formación de cálculos, impidiendo el proceso de cicatrización espontánea de la lesión, causando inflamación e irritación de la mucosa circundante. Las principales causas de la alveólisis son la caries dental y el trauma dentoalveolar. El tratamiento de la alveólisis, generalmente se indica la extracción inmediata. El presente casotrabajo tiene como objetivo describir un reporte de caso de una paciente de género femenino, de 5 años de edad, que presentó alveólisis en el diente primario 51, el cual fue extraído y presentó proceso de cicatrización normal con erupción del diente sucesor 11 sin alteraciones. Cabe al cirujano dentista la búsqueda por informaciones sobre esta patología, saber identificarla y tratarla precozmente, para así mejorar significativamente la calidad de vida de la paciente infantil.


A alveólise é um condição não muito frequente e assintomática. Ocorre quando a raiz do dente torna-se suscetível à presença de biofilme e formação de cálculos, impedindo o processo de cicatrização espontânea da lesão, causando inflamação e irritação da mucosa circundante. As principais causas da alveólise são a cárie dentária e o trauma dentoalveolar. O tratamento da alveólise, geralmente é a exodontia do elemento dentário afetado. O presente trabalho tem como objetivo apresentar um relato de caso de uma criança do gênero feminino, de 5 anos de idade, que apresentou alveólise no elemento dentário 51, o qual foi extraído e apresentou processo de cicatrização normal com irrompimento do elemento 11 sem alterações. Cabe ao cirurgião-dentista a busca pelas informações sobre essa patologia, sabendo identificá-la e trata-la precocemente, para melhorar significativamente a qualidade de vida da criança.


Alveolysis is an asymptomatic and infrequent condition. It occurs when the root of the tooth becomes susceptible to the presence of biofilm and formation of calculi, preventing the process of spontaneous wound healing, causing inflammation and irritation of the surrounding mucosa. The main causes of alveolysis are dental caries and dentoalveolar trauma. In the treatment of alveolysis, immediate exodontia is usually indicated. The present study aims to present a case report of a 5 - year - old female child with alveolysis of primary tooth 51, which was extracted and showed a normal healing process with eruption of successor tooth 11 without alterations. It is up to the dentist to search for information about this pathology, knowing how to identify it and treat it early to significantly improve the child's quality of life.

ABSTRACT

La cavidad oral puede mostrar signos clínicos de enfermedades renales que pasan desapercibidos. El objetivo de este estudio fue evaluar la asociación entre defectos del esmalte (DDE), cálculo dental, bajo peso, baja talla y el diagnóstico de disfunciones tubulares simples o tubulopatías entre 256 pacientes pediátricos (160 con tubulopatías simples y 96 controles sanos) en un importante hospital urbano de Valencia, Venezuela. La frecuencia de DDE en el grupo con tubulopatías fue de 56.25% y en controles de 29.2%, cálculo dental 26.9% y 10.4%, respectivamente. Los modelos de regresión logística revelaron la presencia de DDE (p = 0.000), cálculo dental (p = 0.002), bajo peso (p = 0.000) y baja talla (p = 0.000); cada una de estas características por separado presentó una asociación estadísticamente significativa con tubulopatías. Los niños con DDE tienen 2.7 más posibilidades de afección renal que los que no presentan DDE (Wald = 11.263 y p-valor = 0.001), también los pacientes con cálculo dental son 2.3 veces más propensos a padecer tubulopatías que los que no lo tienen (Wald = 4.076 y p-valor = 0.043) y los niños con bajo peso tienen 53.7% más probabilidad de presentar disfunción tubular simple (Wald = 4.751 y p-valor = 0.029). De allí que se puede afi rmar que la ocurrencia de tubulopatías tiene una asociación estadísticamente significativa con la presencia de DDE, cálculo dental y bajo peso. Estos datos pueden contribuir a que en la consulta odontopediátrica se aumente el número de referencia de niños con tubulopatías por la asociación de las variables mencionadas (AU)


The oral cavity may show clinical signs of renal diseases that go unnoticed. The aim of this study was to evaluate the association between enamel dental defects (EDD), dental calculus, low weight, low height and the diagnosis of simple tubular dysfunctions or tubulopathies among 256 pediatric patients (160 with simple tubulopathies and 96 healthy controls) in an important urban hospital of Valencia, Venezuela. The frequency of EDD in the group with tubulopathies was 56.25% and in controls 29.2%, dental calculus 26.9%, and 10.4%, respectively. The logistic regression models re-vealed that the presence of DDE (p = 0.000), dental calculus (p = 0.002), low weight (p = 0.000) and low size (p = 0.000), each of these characteristics Patients presented a statistically signifi cant association with the presence of tubulopathies. Children with EDD are 2.7 times more likely to have renal disease than those without EDD (Wald = 11.263 and p-value = 0.001); patients with dental calculus are 2.3 times more likely to have tubulopathies than (Wald = 4.076 and p-value = 0.043) and children with low weight were 53.7% more likely to have simple tubular dysfunction (Wald = 4.751 and p-value = 0.029). Hence, it can be affi rmed that the occurrence of tubulopathies has a statistically signifi cant association with the presence of DDE, dental calculus, and low weight. These data may contribute to the increase in the reference number of children with tubulopathies by the association of the mentioned variables (AU)

ABSTRACT

An aqueous leaf extract of the medicinal species Kalanchoe gastonis-bonnieri (here denominated KGB) has been found to be effective as an antimicrobial agent against canine oral cavity bacteria in in vitro assays. In this study, we investigated the effect of topic oral administration of KGB on the development of dental biofilm in Beagle dogs. The experiments were performed with an experimental group (0.2% of KGB extract), a negative control group (0.9% of saline solution) and a positive control group (0.12% chlorhexidine). Each treatment was sprayed into the oral cavity daily for 28 days. Thirty Beagle dogs with similar characteristics and kept under the same management and diet were used. The measurement of dental plaque and calculus was performed using a computerized analytical method. The phenolic profile of KGB extract was analyzed by HPLC-DAD. KGB extract at 0.2% showed efficacy in controlling the formation of plaque compared to the negative control group, and dental calculus in relation to the negative and positive control groups. A significant difference was observed among these three groups. Peaks attributed to flavonoids and phenolic acids were identified in the HPLC-DAD chromatogram of the KGB extract. The presence of these substances could be related to the activity observed. Our findings demonstrate that treatment with KGB is effective in controlling periodontal disease in dogs, providing new insights into the medicinal properties of this plant. KGB extract has a potential use as a supplemental agent in pharmaceutical products for the prevention of periodontal disease.(AU)


Um extrato aquoso de folhas da espécie medicinal Kalanchoe gastonis-bonnieri (aqui denominado como KGB) foi efetivo como um agente antimicrobiano contra as bactérias da cavidade oral de cães em testes in vitro. Neste estudo, investigou-se o efeito da administração oral tópica de KGB sobre o desenvolvimento do biofilme dental em cães da raça Beagle. Os experimentos foram realizados com um grupo experimental (0,2% de extrato de KGB), um grupo controle negativo (0,9% de solução salina) e um grupo controle positivo (0,12% de gluconato de clorexidina). Cada tratamento foi aplicado no interior da cavidade oral diariamente durante 28 dias. Foram utilizados trinta cães da raça Beagle com características semelhantes e mantidos sob o mesmo manejo e dieta. A medição da placa bacteriana e cálculo dentários foi realizada utilizando-se um método de análise computadorizada. O perfil fenólico do extrato de KGB foi analisado por HPLC-DAD. O extrato de KGB a 0,2% mostrou eficácia no controle da formação de placa bacteriana em comparação com o grupo controle negativo, e de cálculo dentário em relação aos grupos controle negativo e positivo. Uma diferença significativa foi observada entre esses três grupos. Picos atribuídos a flavonoides e ácidos fenólicos foram identificados no cromatograma de HPLC-DAD do extrato de KGB. A presença de tais substâncias pode estar relacionada com a atividade observada. Os resultados demonstram que o tratamento com KGB é eficaz no controle da doença periodontal em cães, fornecendo novas perspectivas sobre as propriedades medicinais desta planta. O extrato de KGB tem uma utilização potencial como um agente suplementar em produtos farmacêuticos para a prevenção da doença periodontal.(AU)

ABSTRACT

Objective: The aim of this study was to map the distribution of periodontal disease in adolescents in the Jequitinhonha Valley. Methods: We constructed maps with varying Community Periodontal Index (CPI). The cities were selected based on population size and performance of oral health services. The sampling plan was composed of 450 individuals between 15 and 19 years, randomly selected in number corresponding to the proportion of the adolescent population in each municipality. Results: Of the 450 adolescents examined were 16 (3.5%) code 0 (Healthy), 232 (51.5%) of the code 1 (bleeding), 38 (8.44%) code 2 (Calculus) and 164 (36.44%) code 6 (bleeding and calculus). The pattern of mosaic maps was kind and may indicate that the worst periodontal conditions of adolescents were distributed throughout the region. Conclusion: maps described the oral health status of adolescents and can provide information for planning oral health.

ABSTRACT

En la actualidad los tratamientos estéticos restauradores han adquirido una importancia fundamental dentro de los consul-torios dentales, debido a la importancia que los pacientes han dado a su sonrisa como un factor que les ayuda a mejorar su autoestima y calidad de vida. Paciente de sexo femenino de 39 años de edad, que acudió a la consulta con el deseo de mejorar su sonrisa, debido a que ya recibió un tratamiento anterior pero no se encontraba satisfecha. Al examen clínico presentó agenesia de la pieza dental 22 y en su lugar se encontró un canino con una corona de metal porcelana defectuosa, diastema entre las piezas 23 y 21, atrición de las piezas 11 y 21, discromía de la 12 y asimetría dental de los dientes anterosuperiores. El objetivo del presente caso clínico es describir un método muy riguroso de análisis dentofacial que permita llegar a un diagnóstico preciso y de esta forma establecer un Plan de Tratamiento Integral (Funcional, Biológico y Estético), transformando el canino en incisivo lateral y mejorando la sonrisa de la paciente.


Nowadays aesthetic restorative tratments have accuried a main importance in dental clinics, because of the importance that patients give to their smile as a factor that helps thems to improve their self steem and life quality.

ABSTRACT

A doença periodontal (DP) é uma infecção crônica em resposta à presença de bactérias nos tecidos ao redor do dente, sendo definida como uma doença sujeito e sítio-específica, que evolui continuamente com períodos de exacerbação e de remissão. É uma patologia fortemente associada à presença de cálculo dentário em superfícies radiculares, porém, a superfície áspera do cálculo dental por si só não é suficiente para induzir à inflamação nos tecidos periodontais adjacentes. O cálculo dental atua como um substrato ideal para a colonização microbiana subgengival, e seu papel no desenvolvimento da doença periodontal tem sido investigado em vários estudos. Esta revisão buscou encontrar na literatura disponível estudos recentes sobre a relação existente entre o cálculo dental e a doença periodontal. Diante dos artigos encontrados, concluiu-se que a superfície porosa do cálculo dental abriga um biofilme viável, que propicia o crescimento e o desenvolvimento de periodontopatógenos. Ainda, pôde-se concluir que o papel do cálculo dental na etiologia da DP é secundário e que sua remoção da superfície dentária é essencial na fase inicial da terapia periodontal. Entretanto, nenhum método utilizado para o debridamento da superfície dental é eficaz na eliminação total do cálculo.


Periodontal disease (PD) is a site-specific, chronic infection in response to bacteria surrounding teeth, with periods of exacerbation and remission. It has been strongly associated to dental calculus (DC) at root surfaces; however, the rough nature of radicular tissues is not enough to trigger soft tissue adjacent infl ammation. The dental calculus act as an ideal substrate for subgingival colonization and its role on the development of periodontal disease has been investigated in several articles. The review aimed to identify recent studies on the relationship between PD and dental calculus. Based on the available data, it can be stated that the porous nature of dental calculus harbors an active biofi lm allowing for growth and development of periodontopathogenic microorganisms. Also, it can be said that DC has a secondary role on the PD etiology, and that its removal remains essential in the early phase of periodontal therapy. Nevertheless, no actual debridement method is effective for complete elimination of DC.

ABSTRACT

The purpose of this study was to evaluate the in-vitro efficacy of the active ingredients of dentifrice following treatment time. The whitening effect was evaluated by a change in lightness value relative to the contact time of hydrogen peroxide, by using artificially stained hydroxyapatite discs. The anti-calculus effect was assessed based on the amount of calcium eluted from the human dental calculus by sodium pyrophosphate. Remineralization was evaluated by the Vickers hardness test following the application of sodium fluoride to bovine enamel. In order to view dentinal tubules occlusion, the formation of insoluble calcium salts by bovine dentin specimens was observed using scanning electron microscopy. Change in lightness value (ΔL) was 5.50±1.51 after 1 min of treatment, 5.73±0.43 after 3 min, 8.64±0.24 after 10 min, 18.93±0.76 after 30 min, and 27.35±0.54 after 60 min. The amount of calcium eluted from the human dental calculus was 4.23±0.14 ppm after 1 min of treatment, 4.51±0.04 ppm after 3 min, 12.12±0.16 ppm after 10 min, 17.85±0.81 ppm after 30 min, and 25.15±0.32 ppm after 60 min. The Vickers hardness change value (ΔVHN) was 1.96±1.44 after 1 min, 1.52±1.06 after 3 min, 9.06±0.15 after 10 min, 10.83±5.13 after 30 min, and 12.55±2.09 after 60 min. Partial dentinal tubules occlusion was observed at 10 min and complete occlusion was evident at 60 min. In summary, the use of patch type dentifrices for 10, 30, or 60 min were 1.57 to 8.26 times more effective than using the paste type dentifrices for 1 to 3 min. Based on these findings, it is reasonable to expect that the use of patch type dentifrices for 10 min would lead to remineralization, anti-calculus and dentinal tubules occlusion effects, and that use for 30 min would result in a whitening effect.

ABSTRACT

ABSTRACT: Fetuin-A is a potent inhibitor of calcium-phosphate precipitation and of the calcification process, therefore it can also be related with dental calculus. Thus, we aimed to investigate a possible relationship between fetuin-A gene polymorphism and the presence of dental calculus. A possible relationship between serum, saliva and gingival crevicular fluid (GCF) levels of fetuin-A was also investigated. Fetuin-A c.742C > T and c.766C > G polymorphisms were investigated in 103 patients with or without dental calculus. Additionally, serum, saliva and GCF fetuin-A levels of patients were compared according to dental calculus presence. A significant difference was not observed in the distribution of the fetuin-A c.742C > T and c.766C > G polymorphisms between patients with or without dental calculus. Saliva and GCF fetuin-A concentrations of patients with dental calculus were statistically higher than those without dental calculus (P=0.001, P=0.036 respectively). According to our results, fetuin-A c.742C > T and c.766C > G polymorphisms were not associated with presence of dental calculus. However, higher GCF and saliva fetuin-A levels were detected in patients with dental calculus than in patients without dental calculus, which may result from an adaptive mechanism to inhibit mineral precipitation and eventually calculus formation.

ABSTRACT

O objetivo deste artigo é relacionar as condições gengival e socioeconômica e distribuição demográfica de adolescentes residentes em uma região desfavorecida brasileira. O estudo transversal foi realizado com amostra probabilística de 450 adolescentes (15-19 anos) em 13 municípios sorteados no Vale do Jequitinhonha (MG). A condição gengival foi avaliada por um examinador calibrado (Kappa ≥ 0,85) e baseado Índice Periodontal Comunitário (CPI). Foram calculadas as frequências para indivíduos e sextantes com posterior Análise de Correspondência Múltipla (Anacor) que explorou relações entre o CPI e as características sociodemográficas. Como resultados: 16 (3,6%) apresentaram-se sem alterações gengivais, 235 (52,2%) com sangramento, 36 (8,0%) com cálculo dental e 163 (36,2%) com sangramento e cálculo. A Anacor identificou dois grupos que guardavam semelhanças entre si em relação à doença periodontal. O grupo 1 reuniu os adolescentes com CPI sadio, 19 anos de idade, que trabalham e têm maior renda familiar. No grupo de CPI com sangramento, tem-se os adolescentes com 15 e 16 anos de idade, de ambos os sexos, cursando o ensino fundamental, menor renda familiar e que se autodeclararam pardos ou negros. A gengivite foi relacionada às condições socioeconômicas e demográficas de adolescentes da região.


The scope of this study is to correlate the gingival condition and sociodemographic status of adolescents living in an economically disadvantaged Brazilian region. The survey was conducted with a random sample of 450 adolescents in 13 cities selected in the Jequitinhonha Valley (State of Minas Gerais). The gingival condition was evaluated using a calibrated examiner (Kappa ≥ 0.85). The oral exam was based on the Community Periodontal Index (CPI). The frequencies of individuals were calculated and sextants subsequently assessed using Multiple Correspondence Analysis (ANACOR) to reveal the relationship between CPI and sociodemographic characteristics. The results showed that: 16 (3.6%) were healthy; 235 (52.2%) had gingival bleeding; 36 (8%) had dental calculus and 163 (36.2%) had both bleeding and calculus. ANACOR identified two groups with similarities in relation to periodontal disease. Group one featured 19-year-olds with healthy CPI who work and have higher family income. Group two included 15- and 16-year-olds of both sexes with CPI and gingival bleeding in elementary school with lower family income, who declared themselves to be of mixed or Afro-descendant race. The presence of gingivitis was related to the socioeconomic and demographic characteristics of adolescents in the region.

ABSTRACT

Aim: To determine the relationship between the chemical composition of saliva, periodontal disease and dental calculus. Methods: An observational analytical cross-sectional study was conducted with patients over 55 years of age. Ethical principles of autonomy and risk protection were applied according to the international standards. Sociodemographic and diagnosis variables (presence of dental calculus and periodontal status) were considered to measure salivary concentrations of glucose (by the glucose oxidase/peroxidase method, amylase (by the colorimetric test), urea (by the amount of indophenol), total protein (by the Bradford method) and albumin (by the nephelometric method). Patients chewed a sterile rubber band and 3 mL of stimulated saliva were collected. The samples were stored at -5 °C, centrifuged at 2,800 rpm for 10 min, and the supernatant was removed and stored at -20 °C. Data were presented as frequencies and proportions for qualitative variables and measures of central tendency and dispersion for quantitative variables. Data were analyzed by either analysis of variance or Kruskal Wallis test . A p value <0.05 was considered statistically significant. Results: Significant relationships were observed between the concentration of salivary urea and periodontal status (p = 0.03) and the presence of dental calculus and urea (p = 0.04) was demonstrated. Conclusions: A relationship between the salivary urea concentration and the presence of periodontal disease and dental calculus is suggested.

ABSTRACT

The aim of this study was to compare the residual content of tetrasodium pyrophosphate released by two different anticalculus dental flosses (Reach PP(r) - entangled polypropylene floss and Reach NT(r) - texturized nylon) in the oral cavity. Ten healthy individuals (aged between 18 and 30 years) were enrolled in this randomized crossover clinical investigation. Participants received instructions on daily dental flossing and the interventions were randomly performed in 2 different groups (NT or PP) of five individuals each according to the dental flosses. Individuals were instructed to use each dental floss with a total of six slides on the two interproximal aspects of target teeth (3 slides on each interproximal aspect). A washout period of one week was used before start flossing interventions and after each type of dental floss to prevent any bias related to the exposure to any product that contained the active ingredient. Samples were collected by #35 sterilized absorbent paper points from interdental fluid after flossing and assessed by ion chromatography. The levels of residual tetrasodium pyrophosphate were evaluated by means of binomial generalized linear model proportions and canonical link function. Both dental flosses were effective in tetrasodium pyrophosphate release at therapeutic levels in the interdental gingival crevicular fluid for a period of up to 2 h after use. No significant differences were found between both groups (p>0.05). It may be concluded that both material composition and physical structure of the new dental floss did not affect the release or the maintenance of anticalculus agent at therapeutic levels for a period of up to 2 h after single use.


O objetivo deste estudo foi comparar o teor residual de pirofosfato de tetrasodio liberado por dois tipos diferentes de fio dental anti-cálculo (Reach PP(r) - polipropileno entrelaçado e Reach NT(r) - nylon texturizado) na cavidade oral. Dez indivíduos saudáveis (com idade entre 18 e 30 anos) foram selecionados para este estudo clínico em modelo crossover. Os participantes receberam instruções sobre como utilizarem os fios dentais e as intervenções foram randomicamente realizadas em 2 grupos de 5 participantes de acordo com o tipo de fio avaliado. O participantes foram instruídos a passarem cada fio dental em um total de 6 passadas ao redor dos 2 espaços interproximais dos dentes selecionados (3 passadas em cada face interproximal). Um período de washout de 1 semana foi utilizado antes do início do estudo e após cada intervenção com o objetivo de prevenir a ocorrência de viés relacionado à exposição de algum agente terapêutico. Amostras do fluido interdental após as intervenções foram avaliadas por meio de cromatografia de íons. A porcentagem residual de pirofosfato tetrassódico foi verificada empregando-se o método da cromatografia de íons, pela colheita do fluido interdental com cones de papel absorvente esterilizados. Os teores de pirofosfato tetrassódico residual foram comparados para cada fio dental e para cada tempo de colheita do fluido interdental. Não foram observadas diferenças significantes entre os grupos avaliados (p>0,05). Conclui-se que a composição do material e a estrutura física dos fios dentais não exerceram influência na liberação e na permanência do agente anti-tártaro, que permaneceu em níveis terapêuticos por um período de até 2 h após o uso único.

ABSTRACT

The aim of this study was to describe malocclusion prevalence and its association with individual and contextual factors among Brazilian 12-year-old schoolchildren. This cross-sectional study included data from an oral health survey carried out in Goiânia, Brazil (n = 2,075), and data from the files of the local health authority. The data were collected through oral clinical examinations. The Dental Aesthetic Index (DAI) was used to assess occlusion. The presence of malocclusion (DAI > 25) was used as the dependent variable. The individual independent variables consisted of adolescents’ sex and race and their mothers’ level of schooling. The clinical variables were caries experience and presence of adverse periodontal condition (calculus and/or gingival bleeding). The contextual variables included type of school and the location of schools in the city’s health districts. The Rao-Scott test and multilevel logistic regression were performed. The prevalence of malocclusion was 40.1%. In the final model, significantly higher rates of malocclusion were found among those who attended schools located in less affluent health districts and whose mothers had fewer years of education. Rates were also higher among those presenting calculus and/or gingival bleeding. Malocclusion demonstrated a high prevalence rate and the inequalities in its distribution were determined by individual and contextual factors.

ABSTRACT

Periodontal disease is a chronic multifactor pathology, characterized by the progressive destruction of the dental structures support tissues. Patients with some type of disability have a higher predisposition to develop periodontal disease, due to bad hygiene, product of their motor and psychological deficiencies, and to their systemic alterations that difficult the defense against periodontopathogenic microorganisms. The purpose of this study was to evaluate and compare the periodontal status of a group of children with special needs, and a control group. 47 patients with mental retardation and Down syndrome from three special education centers, and 31 healthy patients of ages ranging from 6 to 15 years, were dentally evaluated, to determine their plaque index, gingival index, and the presence of calculus. After gathering the data and tabulating the results, a 1.08 plaque index was determined, and a gingival index of 1.03, corresponding to a mild gingivitis in the study group. On the other hand, on the group of regular patients, there was a 1.08 PI and a 0.96 GI. Calculus percentage was similar on both groups. However, a large percentage of children with mild gingival inflammation was observed in the group of special patients (53.19 percent,) compared to the control group (29 percent).


La enfermedad periodontal es una patología crónica y multifactorial donde ocurre una progresiva destrucción de los tejidos de soporte de las estructuras dentales. El desarrollo de la enfermedad periodontal está dado inicialmente por la presencia de placa dental que aunado a factores inmunológicos, hormonales y celulares conllevan a un desarrollo más rápido o agresivo. Los pacientes que presentan algún tipo de discapacidad, tienen una predisposición mayor a desarrollar enfermedad periodontal debido a la mala higiene por sus deficiencias motoras y psíquicas y a sus alteraciones sistémicas que dificultan la defensa ante los microorganismos periodontopatógenos. El propósito de este estudio fue evaluar y comparar el estatus periodontal de un grupo de niños con necesidades especiales y un grupo control. 47 pacientes con Retardo mental y Síndrome de Down pertenecientes a tres centros de educación especial y 31 pacientes sanos con edades comprendidas entre 6 y 15 años fueron evaluados odontológicamente, determinándose el índice de placa, el índice gingival y la presencia de cálculo. Posterior a la obtención y tabulación de los resultados, se determinó un índice de placa de 1.08 que se corresponde con la presencia de una placa adherida leve y un índice gingival de 1.03 que se corresponde con una gingivitis leve en el grupo de estudio. Por el contrario, en el grupo de pacientes regulares se obtuvo 1.08 de IP y 0.96 de IG. El porcentaje de cálculo fue similar en ambos grupos, 48.94 por ciento en el grupo de estudio y 45.16 por ciento en el grupo sano. Sin embargo, se observó un alto porcentaje de niños con inflamación gingival moderada en el grupo de pacientes especiales (53.19 por ciento) comparado con el grupo control (29 por ciento).

ABSTRACT

Objetivos: relatar um caso clínico e analisar a relação do fluxo salivar e da capacidade tampão da saliva na formação do cálculo supragengival em uma paciente com alto grau de formação, através da realização de testes salivares para quantificar essas variáveis. Métodos: foram realizadas três coletas salivares com intervalos de tempo mínimo de um mês entre elas. Para a mensuração do fluxo salivar, a salivação foi estimulada através da utilização de uma lâmina de parafina durante cinco minutos, e o volume obtido foi dividido por cinco, obtendo-se dessa forma a relação mL/min. Para a análise da capacidade tampão da saliva, foi realizada a leitura de pH após a adição de 1 ml da saliva coletada com 3 mL de ácido clorídrico a 0,005 N, seguido pela homogeneização e repouso da mistura por dez minutos. A leitura do valor do pH salivar final foi registrada através de um eletrodo de pH acoplado a um potenciômetro. Resultados: como médias dos valores do fluxo salivar e da capacidade tampão, obteve-se respectivamente 2,13 m L/min e pH 5,26. Conclusão: as variáveis "fluxo salivar e capacidade tampão" mostraram-se sem uma relação direta com a tendência de formação de cálculo dental da paciente. Como fator determinante para o quadro clinico apresentado, pôde-se constatar o baixo grau de instrução sobre higiene bucal, influenciado pelo fator socioeconômico.
