Is there an association between family structure and the oral health of socially vulnerable children?

Abstract The aim of this study was to evaluate the impact of the family structure on the oral health status of socially vulnerable children in the Federal District of Brazil. A total of 471 schoolchildren with a mean age of 8.12 (± 0.90) years were examined for dental caries using the CAST instrument. Dental biofilm and oral pain were also registered. Children's guardians were interviewed about socioeconomic variables and oral hygiene habits. The association between oral pain in the previous 30 days and the child's maximum CAST score were analyzed using the Pearson chi-squared test. Multivariate Poisson regression models with robust variance were used to determine the predictors of presence of biofilm, oral pain, and caries severity. The prevalence of cavitated dentin lesions was 43.74% and, both dentin and enamel lesions, 52.87%; for both dentitions. An association between pain and severe nontreated carious lesions was found (p < 0.0001). The family structure was not related to the presence of dental caries, but a significant association was found between low maternal education and severe carious lesions (PR = 1.41; p = 0.0077) and oral pain (PR = 1.47; p = 0. 0335); not owning a residence and frequency of toothbrushing were also associated with the substantial presence of biofilm (PR = 1.13, p = 0.0493 and PR = 1.18, p = 0.0470; respectively). For socially vulnerable children, variables related to the socioeconomic status of the families were more relevant than the family structure in relation to their oral health status.

Minimum intervention oral care: defining the future of caries management

Abstract It is not uncommon that oral healthcare professionals and researchers interchange the use of the terms minimum/minimal intervention and minimally invasive dentistry. However, these terms apply to two different, but related, concepts. Minimum intervention dentistry, to be more appropriately addressed in this paper as minimum intervention oral care (MIOC), is an oral healthcare delivery framework that encompasses four interlinked clinical domains. These domains are: identifying disease - detection, longitudinal risk/susceptibility assessment, investigation, diagnosis and the development of a personalized care plan; prevention of lesions/control of disease - patient behaviour management, non-invasive remineralisation of the enamel and dentine, biofilm and diet control, micro-invasive sealants and infiltration techniques to arrest and reverse incipient lesions; minimally invasive operative procedures including selective carious dentine removal, the "5Rs" management of the tooth-restoration complex (review, refurbish, re-seal, repair and replace) amongst other restorative interventions; and tailored recall/review/re-assessment consultations. This framework includes that minimally invasive operative dentistry (MID), that although a critical operative clinical domain, should be viewed as one of the pillars of minimum intervention oral healthcare (MIOC), applied across all disciplines of restorative dentistry, not just caries management. The aim of this review is to clarify these differences and emphasize the importance of minimally invasive operative dentistry (MID) within the context of minimum intervention oral care (MIOC). MIOC is applicable to all disciplines within restorative dentistry, including clinical caries management.

Impact of dental treatment on the oral health-related quality of life of Brazilian schoolchildren

Abstract: This before-after experimental study evaluated the impact of dental treatment on the oral health-related quality of life (OHRQoL) in children aged 6-8 years from Paranoá, DF, considering the presence or absence of cavitated dentin carious lesions pre- and post-treatment. The responsiveness and sensitivity of the questionnaires were also investigated. Caries was detected by using the Caries Assessment Spectrum and Treatment (CAST) instrument, while the impact of oral health on the children's health-related quality of life was assessed using the Brazilian version of the Child Perceptions Questionnaire (CPQ8-10), which was completed by the children and the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS), which was completed by their parents. Sociodemographic characteristics were also assessed. After the examinations, the children were categorized into two groups according to the presence (treatment/n = 34) or absence (control/n = 34) of cavitated dentin carious lesions. Restorative/curative care was provided to the treatment group, while the control group received preventive measures. OHRQoL was assessed at baseline and at four weeks post-treatment. No significant sociodemographic differences were observed between the groups. In the treatment group, the children and their families reported a greater impact of oral health on their OHRQoL in both questionnaires (p < 0.05). However, there was a significant reduction in the impact of oral health, with differences between the pre-treatment and post-treatment phases (p = 0.001). Good sensitivity and responsiveness were observed for both questionnaires. Dental treatment was found to reduce the negative impact of dental caries on OHRQoL in 6-8-year-old children, which was detected by both questionnaires (B-ECOHIS and CPQ8-10).

Is there an association between dental caries, fluorosis, and molar-incisor hypomineralization?

Abstract Objective: This cross-sectional study aimed to determine the prevalence of dental caries, dental fluorosis, and molar-incisor hypomineralization, and their associations in a group of Brazilian schoolchildren. Methodology: Adolescents (n=411) were evaluated by two calibrated examiners for dental caries (DC), dental fluorosis (DF), and molar-incisor hypomineralization (MIH) using the CAST (Caries Assessment Spectrum and Treatment) instrument, Thylstrup and Fejerskov (TF) index, and MIH Severity Scoring System (MIH-SSS), respectively. Descriptive statistics, chi-square tests, and logistic regression were used for statistical analysis. Results: The sample comprised 42.75% boys and 57.25% girls. The prevalence of DC in permanent dentition was 94.75%, of which 29% were represented by dentin lesions. For DF, a prevalence of 40.75% was observed, with 69.32% mild, 12.88% moderate, and 17.79% severe. A positive association between the source of water and fluorosis was detected (p=0.01). The prevalence of MIH was 18%. Thirty adolescents (41.7%) presented with severe MIH. No association was found between DF or MIH and dentin DC or between MIH and DF at the individual level. However, a significant negative relationship was detected between DF and dentin carious lesions ( p <0.005) and DF and MIH ( p <0.00001) at the tooth level, whereas a positive association was observed between MIH and dentin carious lesions ( p <0.00001). A positive association was also observed between the severity of both conditions ( p <0.00001). Mild DF was the most prevalent problem observed. Cases of teeth with mild MIH were the most predominant in MIH-affected teeth. Conclusions: No association was observed among the dentin carious lesions, MIH, and DF at the participant level. However, a positive association between MIH and dentin carious lesions was found at the tooth level, whereas MIH, DF, and DF and dentin carious lesions showed a negative relationship.

Discriminant validity of the CAST instrument compared to the dmf index in the deciduous dentition: a cross sectional study

Abstract This study aimed to assess the discriminant validity of the Caries Assessment Spectrum and Treatment (CAST) at different thresholds, compared with the Decayed, Missing, and Filled Teeth Index (dmf) instrument, to discriminate caries risk factors. A cross-sectional study was conducted including children aged 2-5 years from preschools in Southern Brazil. Parents answered a questionnaire, and children were clinically examined using the CAST instrument and, in the following weeks, using the dmf index. Two caries thresholds were adopted for CAST: caries in dentin (CAST4-7/CAST2,4-8) and enamel caries (CAST3-7/CAST2-8). Poisson regression was used in the analysis (p < 0.05). A total of 200 children were included. The prevalence of caries was 47.0% with dmf, 42.5% with CAST4-7, and 77.5% with CAST3-7. When the outcome was caries prevalence, CAST4-7 discriminated between sexes, household crowding, and dental pain, and CAST3-7 discriminated age and family income, while the dmf was associated with dental pain. When experience of caries was the outcome, all the criteria discriminated between sexes, age, family income, household overcrowding, visible dental plaque, and dental pain, while dmf and CAST2-8 also discriminated maternal schooling. The CAST discriminated caries risk factors similar to the dmf index when caries experience was the outcome. When prevalence was considered, CAST was able to discriminate for more individual characteristics than dmf.

CAST instrument in epidemiological surveys: Results presentation in comparison to the WHO criteria / Uso do instrumento CAST em levantamentos epidemiológicos: apresentação dos resultados em comparação ao critério da OMS

Resumo O CAST (Caries Assessment Spectrum and Treatment) é um instrumento desenvolvido para a detecção de cárie a ser utilizado em levantamentos epidemiológicos. Foi validado e tem se mostrado efetivo, fornecendo um diagnóstico mais preciso do estado de saúde bucal do que o critério OMS, recomendado pela Organização Mundial da Saúde. O objetivo deste artigo é comparar a apresentação dos resultados de cárie dentária utilizando o instrumento CAST e o critério OMS, numa mesma população. Foram avaliados por dois examinadores treinados na utilização do instrumento CAST 680 escolares de 6 a 8 anos do Distrito Federal, Brasil. A avaliação constou do índice de placa visível (IPV) e do índice de sangramento gengival (ISG). Os escores CAST dente foram convertidos em componentes ceo/CPO e calculados os ceod/CPOD. Os pais responderam a um questionário sociodemográfico. A idade média foi 7,45 anos (± 0,91). A prevalência de cárie na dentição decídua foi de 65,44% e 61,61%, considerando o CAST e o critério da OMS, respectivamente; na dentição permanente: 38,19% e 10,2%, respectivamente. A média do ceod foi de 2.4 (± 2.7) e a média do CPOD 0.16 (± 0.53). o IPV foi associado a maiores CAST máximos p < 0,005. O instrumento CAST demonstrou maior sensibilidade em identificar a presença e gravidade de lesões cariosas quando comparado ao critério OMS.

Abstract Caries Assessment Spectrum and Treatment (CAST) is an instrument developed for caries detection to be used in epidemiological surveys; it has been validated and is believed to provide a clearer picture of the oral health status than the criteria provided by the World Health Organization (WHO). This article aims to compare the epidemiological survey results using the CAST instrument and the WHO criteria in the same population. 680 schoolchildren aged 6-8 years from Federal District, Brazil, were evaluated by two examiners trained to use the CAST. The visible plaque index (VPI) and gingival bleeding index (GBI) were also evaluated. The maximum CAST codes per tooth were converted into the dmf/DMF, the mean scores for primary and permanent dentition were calculated. The mean age was 7.45(± 0.91) years. The prevalence of caries differed when CAST and the WHO criteria were applied. In the primary dentition, it was 65.44% and 61.61%, and for the permanent dentition, 38.19% and 10.2%, respectively. It was possible to calculate the mean dmft [2.4(± 2.7)] and the DMFT [0.16(± 0.53)] using CAST. VPI was associated with higher maximum CAST scores p < 0,005. The way CAST results are presented showed a higher sensibility to identify the presence and severity of carious lesions in comparison to the WHO criteria.

Mechanical and optical properties of conventional restorative glass-ionomer cements - a systematic review

Abstract Objectives To perform a systematic review of test methodologies on conventional restorative glass-ionomer cement (GIC) materials for mechanical and optical properties to compare the results between different GICs. Material and Methods Screening of titles and abstracts, data extraction, and quality assessments of full-texts were conducted in search for in vitro studies on conventional GICs that follow the relevant specifications of ISO standards regarding the following mechanical and optical properties: compressive strength, flexural strength, color, opacity and radiopacity. Sources The Latin American and Caribbean Health Sciences (LILACS), Brazilian Bibliography of Dentistry (BBO) databases from Latin-American and Caribbean System on Health Sciences Information (BIREME) and PubMed/Medline (US National Library of Medicine - National Institutes of Health) databases were searched regardless of language. Altogether, 1146 in vitro studies were selected. Two reviewers independently selected and assessed the articles according to pre-established inclusion/exclusion criteria. Among all the properties investigated, only one study was classified as being of fair quality that tested compressive strength and was included. It was observed that many authors had not strictly followed ISO recommendations and that, for some properties (diametral tensile strength and microhardness), there are no guidelines provided. Conclusions It was not possible to compare the results for the mechanical and optical properties of conventional restorative GICs due to the lack of standardization of studies.

Caries prevalence among Brazilian indigenous population of urban areas based on the 2010 National Oral Health Survey / Prevalência de cárie na população indígena Brasileira de áreas urbanas com base no levantamento de Saúde Bucal Nacional - 2010

Abstract It is important to have an epidemiological understanding of oral diseases among indigenous persons, in order to contribute with the organization of health services for these populations. The SB Brasil 2010 database was used to compare the prevalence of dental caries among 308 self-identified indigenous and 37,211 non-indigenous individuals from urban areas, in the following age/age-groups: 5, 12, 15-19, 35-44, 65-74. The study also analyzed the effect of the complex sample design and the sample weight in the outcomes. Kruskal-Wallis, Wilcoxon Scores (Rank Sums), logistic and multiple linear regressions were used for statistical analysis. The mean dmft index for indigenous and non-indigenous children aged five were 4.02 ± 4.01 and 2.41 ± 3.35, respectively, and 46% of non-native and 30.8% of native children were caries-free. The mean DMFT for indigenous and non-indigenous were 10.90 ± 11.69 and 10.93 ± 11.58, respectively, for all age groups when not taking into account the sample weight effect. When considering the complex sample design and the sample weight effect, the study found a statistical significant difference. The results lend credence to suspicions that in Brazil there are disparities in the patterns of caries between self-identified indigenous and non-indigenous individuals.

Resumo É importante ter uma compreensão epidemiológica das doenças orais entre as populações indígenas, a fim de contribuir com a organização dos serviços de saúde para essas populações. O banco de dados SB Brasil 2010 foi utilizado para comparar a prevalência de cárie entre os 308 autoidentificados indígenas e 37.211 indivíduos não indígenas de áreas urbanas, nas idades/grupos etários: 5, 12, 15-19, 35-44, 65-74. O estudo também analisou o efeito do desenho amostral complexo e o peso da amostra nos resultados. Kruskal-Wallis, Wilcoxon Scores (Rank Sums), regressão logística e linear múltipla foram utilizados para análise estatística. O índice ceo-d médio para crianças indígenas e não indígenas com idade de cinco foram 4,02 ± 4,01 e 2,41 ± 3,35, respectivamente, e 46% dos não nativos e 30,8% das crianças nativas estavam livres de cárie. A média CPOD para indígenas e não indígenas foram 10,90 ± 11,69 e 10,93 ± 11,58, respectivamente, para público em geral, quando não levando em conta o efeito do peso da amostra. Ao considerar o desenho amostral complexo e o efeito do peso da amostra, o estudo encontrou uma diferença estatisticamente significativa. Os resultados dão crédito às suspeitas de que no Brasil existem disparidades nos padrões de cárie entre indivíduos indígenas e não indígenas autoidentificados.

3-year survival rates of retained composite resin and ART sealants using two assessment criteria

Abstract The aim was to test the null-hypothesis that there is no difference in the cumulative survival rate of retained composite resin (CR) sealants and a high-viscosity glass-ionomer Atraumatic Restorative Treatment (ART) sealant in first permanent molars calculated according to the traditional and the modified retention assessment criteria over a period of 3 years. This cluster-randomized controlled clinical trial consisted of 123 schoolchildren, 6–7-years-old. At baseline, high-caries risk pits and fissures of fully erupted first permanent molars were treated with CR and ART sealants. Evaluations were performed after 0.5, 1, 2 and 3 years. Retention was scored for free-smooth surface and for each of three sections into which the occlusal surface had been divided. The modified criterion differed from the traditional in that it determined an occlusal sealant to be a failure when at least one section contained no visible sealant material. Data were analysed according to the PHREG model with frailty correction, Wald-test, ANOVA and t-test, using the Jackknife procedure. The cumulative survival rates for retained CR and ART sealants in free-smooth and occlusal surfaces for both criteria were not statistically significantly different over the 3 years. A higher percentage of retained CR sealants on occlusal surfaces was observed at longer evaluations. Cumulative survival rates were statistically significantly lower for the modified criterion in comparison to the traditional. The modified retention assessment criterion should be used in future sealant-retention studies.

Tratamento Restaurador Atraumático: atualidades e perspectivas / Atraumatic Restorative Treatment: advances and perspectives

O Tratamento Restaurador Atraumático (Atraumatic Restorative Treatment) atualmente é entendido como uma abordagem minimamente invasiva que compreende medidas preventivas, terapêuticas e restauradoras em relação à cárie dental e no controle dessa doença, inclusive no atendimento à pacientes especiais. O tratamento é feito apenas com a utilização de instrumentos manuais e com o uso do cimento de ionômero de vidro (CIV), aplicado para o selamento de cicatrículas e fissuras em risco de cárie e na restauração de dentes com cavidades nas quais as fissuras adjacentes também são seladas. As razões mais frequentes para as falhas das restaurações ART estão associadas ao deslocamento do ionômero de vidro em função de insuficiente remoção de esmalte desmineralizado e dentina decomposta; manipulação inadequada do pó/líquido do ionômero de vidro; grau de umidade e temperatura da mistura do ionômero no momento da manipulação; não preenchimento completo da cavidade com o material restaurador; contaminação por saliva e/ou sangue; limpeza ou condicionamento insuficiente das cavidades; grau de cooperação do paciente; habilidade do operador. Materiais com propriedades estéticas melhoradas têm surgido no mercado odontológico e devem servir de estímulo para a realização de trabalhos de ART nos dentes anteriores. No preparo do dente para as restaurações de ART de Classe II, é recomendável confeccionar retenções adicionais nas paredes vestibular e lingual para evitar o deslocamento da restauração. O ART é capaz de diminuir o nível de ansiedade e medo dos pacientes quando o operador não é um especialista, além de ser um tratamento que proporciona menor dor e desconforto, podendo ser realizado num consultório odontológico ou fora dele. Sugestões para novas agendas de pesquisa sobre o ART são propostas.

The Atraumatic Restorative Treatment (A R T) is understood as a minimally invasive approach comprising preventive, therapeutic and restorative measures in relation to dental caries and in the control of this disease, including in attendance to patients of special needs. The treatment is done only with the use of hand instruments and with the use of glass ionomer cement (GIC), applied to the sealing of pits and fissures in caries risk and in the restoration of teeth with cavities in which the adjacent pits and fissures are also sealed. The most frequent reasons for the failures of ART restorations are the displacement of the glass ionomer due to inadequate removal of demineralized enamel and dentin decomposed; improper handling of the glass ionomer powder and liquid; degree of humidity and temperature of the mix GIC at the time of handling; not full fill of the cavity with the restorative material; contamination by saliva and/or blood; cleaning or conditioning of cavities; degree of cooperation of the patient; skill of the operator. Materials with improved aesthetic properties have emerged on the market and must serve as a stimulus for the works of ART in the anterior teeth. In the preparation of the tooth for class II ART restorations, we recommend that you make additional retentions in the vestibular and lingual walls to prevent the displacement of the restoration. The ART is able to reduce the level of anxiety and fear of patients when the operator is not an expert, and is a treatment that provides less pain and discomfort, and can be performed in a dental office or out of it. Suggestions for new research agendas on the ART are proposed.

Caries risk assessment in schoolchildren - a form based on Cariogram® software

Identifying caries risk factors is an important measure which contributes to best understanding of the cariogenic profile of the patient. The Cariogram® software provides this analysis, and protocols simplifying the method were suggested. Objectives: The aim of this study was to determine whether a newly developed Caries Risk Assessment (CRA) form based on the Cariogram® software could classify schoolchildren according to their caries risk and to evaluate relationships between caries risk and the variables in the form. Material and Methods: 150 schoolchildren aged 5 to 7 years old were included in this survey. Caries prevalence was obtained according to International Caries Detection and Assessment System (ICDAS) II. Information for filling in the form based on Cariogram® was collected clinically and from questionnaires sent to parents. Linear regression and a forward stepwise multiple regression model were applied to correlate the variables included in the form with the caries risk. Results: Caries prevalence, in primary dentition, including enamel and dentine carious lesions was 98.6%, and 77.3% when only dentine lesions were considered. Eighty-six percent of the children were classified as at moderate caries risk. The forward stepwise multiple regression model result was significant (R2=0.904; p<0.00001), showing that the most significant factors influencing caries risk were caries experience, oral hygiene, frequency of food consumption, sugar consumption and fluoride sources. Conclusion: The use of the form based on the Cariogram® software enabled classification of the schoolchildren at low, moderate and high caries risk. Caries experience, oral hygiene, frequency of food consumption, sugar consumption and fluoride sources are the variables that were shown to be highly correlated with caries risk. .

Efficacy of casein derivate CPP-ACP1 / Eficácia clínica do complexo de caseína CPP-ACP1

OBJECTIVE: A literature review of systematic reviews and in situ and in vivo randomized controlled trials was conducted in order to assess the role of casein phosphopeptide - amorphous calcium phosphate in providing caries-preventive effect superior to any intervention or placebo. METHODS: Initially, Pubmed database was searched for systematic reviews. Two systematic reviews were identified, which concluded that the quantity and quality of randomized controlled trials were insufficient to recommend the clinical use of the product. After this, Pubmed database was searched for in situ and in vivo randomized controlled trials that were not included in the reviews identified. In vivo and in situ studies yielded mixed results. RESULTS: In situ studies indicated greater efficacy of casein phosphopeptide - amorphous calcium phosphate in comparison with placebo. Whereas, in vivo studies demonstrated different findings CONCLUSION: Casein phosphopeptide - amorphous calcium phosphate had a performance equivalent to or greater efficacy than placebo; fluoride was more effective than the casein complex; casein phosphopeptide - amorphous calcium phosphate associated with fluoride showed better or equivalent performance to that of placebo. In view of available evidence, it was not possible to generalize the indication of casein phosphopeptide - amorphous calcium phosphate for preventing dental caries. Further studies on the preventive effect and longer treatment applications ...

Salivary and serum cortisol levels, salivary alpha-amylase and unstimulated whole saliva flow rate in pregnant and non-pregnant / Niveis de cortisol salivar e serico, alfa-amilase e fluxo de saliva total nao estimulada em gestantes e nao gestantes

PURPOSE: To compare salivary and serum cortisol levels, salivary alpha-amylase (sAA), and unstimulated whole saliva (UWS) flow rate in pregnant and non-pregnant women. METHOD: A longitudinal study was conducted at a health promotion center of a university hospital. Nine pregnant and 12 non-pregnant women participated in the study. Serum and UWS were collected and analyzed every trimester and twice a month during the menstrual cycle. The salivary and serum cortisol levels were determined by chemiluminescence assay and the sAA was processed in an automated biochemistry analyzer. RESULTS: Significant differences between the pregnant and non-pregnant groups were found in median [interquartile range] levels of serum cortisol (23.8 µL/dL [19.4-29.4] versus 12.3 [9.6-16.8], p<0.001) and sAA (56.7 U/L [30.9-82.2] versus 31.8 [18.1-53.2], p<0.001). Differences in salivary and serum cortisol (µL/dL) and sAA levels in the follicular versus luteal phase were observed (p<0.001). Median UWS flow rates were similar in pregnant (0.26 [0.15-0.30] mL/min) and non-pregnant subjects (0.23 [0.20-0.32] mL/min). Significant correlations were found between salivary and serum cortisol (p=0.02) and between salivary cortisol and sAA (p=0.01). CONCLUSIONS: Serum cortisol and sAA levels are increased during pregnancy. During the luteal phase of the ovarian cycle, salivary cortisol levels increase, whereas serum cortisol and sAA levels decline. .

OBJETIVO: Comparar os níveis de cortisol sérico e salivar, alfa-amilase salivar (sAA) e fluxo de saliva não estimulada (UWS) em gestantes e não gestantes. MÉTODOS: Trata-se de um estudo longitudinal realizado no centro de promoção da saúde de um hospital universitário. Nove gestantes e 12 não gestantes participaram do estudo. Foram coletados e analisados soro e UWS nos três trimestres gestacionais e duas vezes por mês durante o ciclo menstrual. A análise do cortisol salivar e sérico foi realizada com o uso de quimiluminescência e a atividade da sAA foi determinada por meio de analisador automático para bioquímica. RESULTADOS: Foi verificado que a mediana (intervalo interquartil) dos níveis de cortisol sérico no grupo de gestantes foi maior que 23,8 µL/dL (19,4-29,4) quando comparado ao grupo de não gestantes, que teve média de 12,3 (9,6-16,8; p<0,001). Os níveis de sAA seguiram o mesmo padrão, com médias de 56,7 U/L (30,9-82,2) e 31,8 (18,1-53,2; p<0,001), respectivamente. Foram observadas diferenças dos níveis de cortisol sérico e salivar (µL/dL) e de sAA entre a fase folicular versus a fase lútea (p<0,001). As medianas dos fluxos salivares (UWS) foram semelhantes em gestantes (0,26 [0,15-0,30] mL/min) e não gestantes (0,23 [0,20-0,32] mL/min). Foram encontradas correlações significativas entre o cortisol salivar e o sérico (p=0,02) e entre o cortisol salivar e a sAA (p=0,01). CONCLUSÕES: Os níveis de cortisol sérico de sAA durante a gestação elevam-se. Na fase lútea do ciclo ovariano, os níveis de cortisol salivar aumentam ao passo que os níveis de cortisol sérico e sAA diminuem. .

Intrusão traumático: como o ortodontista deve proceder? / Traumatic intrusion: how should the orthodontist proceed?

Entre os eventos traumáticos que acometem a dentição permanente, a intrusão (luxação intrusiva) é particularmente complexa, por requerer cuidados multidisciplinares e por colocar o ortodontista diante de sequelas que complicam o prognóstico dos dentes afetados. O diagnóstico é peça fundamental no tratamento, pois após a identificação do problema é que será escolhida a abordagem terapêutica. O tratamento vai depender da quantidade de intrusão, do desenvolvimento radicular, da presença de fratura coronária ou de mobilidade, da condição periodontal, do tempo decorrido desde o trauma, e da motivação e cooperação do paciente e de seus pais. As possíveis terapias variam entre a espera pela reeerupção passiva, o tracionamento ortodôntico e o tracionamento cirúrgico do dente em questão. Por ser relativamente raro em dentes permanentes, poucos dados sobre esse assunto estão disponíveis na literatura odontológica. O objetivo deste trabalho foi realizar em levantamento bibliográfico, complementado por exemplos clínicos, para ajudar o ortodontista a entender a dinâmica desse evento e fornecer subsídios para o tratamento clínico.

Doença de Alzheimer: características e orientações em Odontologia / Alzheimer's disease: characteristics and guidelines in dentistry

A demência é classificada como uma desordem mental de caráter neurodegenerativo que atinge o Sistema Nervoso Central. A doença de Alzheimer é a forma de demência mais prevalente que acomete pessoas idosas e é definida como a perda progressiva e persistente demúltiplas áreas das funções intelectuais. Promove gradual deteriorização da memória, aprendizado, orientação, estabilidade emocional e capacidade de comunicação. Além disso, pensamentos abstratos (paranóias e alucinações) e o declínio dos cuidados pessoais, como tomar banho e a realização da higiene bucal são comuns, interferindo na vida social e diária do indivíduo. De acordo com a evolução, a doença de Alzheimer é dividida em três fases distintas: inicial, intermediária e final. Este estudo objetiva abordar as características e sugerir orientações ao atendimento odontológico nas fases representativas da evolução desse quadro demencial. O cirurgião-dentista deve ter conhecimento dos diferentes estágios desta doença e suas características para direcionar a atenção em saúde bucal de forma individualizada a seus pacientes. A participação dos cuidadores, familiares, além da equipe de saúde é fundamental e também necessária para a manutenção da saúde bucal desses idosos.

Dementia is classified as a mental disorder of a neurodegenerative nature that affects the Central Nervous System. Alzheimer's disease is the most prevalent form of dementia that affects elderly people and it is defined as a progressive and persistent loss of multiple areas of intellectual functions. It gradually promotes deterioration in memory, learning, orientation, emotional stability and ability to communicate. Moreover, abstract thinking (paranoia and hallucinations) and the decline of personal care such as bathing and performing oral hygiene are common, interfering in the individual's social and daily life. According to its development, Alzheimer's disease is divided into three distinct stages: initial, intermediate and terminal stage. The aim of this study was to approach the characteristics and suggest guidelines for dental attendance in the representative stages in the development of this dementia condition. The dentist should be aware of the different stages of this disease and its characteristics to provide patients with individual oral health attention. The participation of caregivers, family, and the health team is fundamental and it is also necessary to maintain oral health of these elderly patients.

The correct use of the ART approach

Confusion exists amongst dentists and scientists about the correct use of the caries management approach termed atraumatic restorative treatment (ART). Inconsistent use of the original definition of ART and suggested modifications (mART) have led to misunderstanding, misconception and miscommunication in the dental literature over the last decade. The aim of this paper is to contribute to a uniform understanding and use of the term ART. Adherence to its original description is suggested and two major aspects were addressed: the use of hand instruments only and the use of adhesive materials and systems.

Avaliação da condição periodontal e da presença de biofilme lingual como indicadores de risco para halitose / Evaluation of periodontal condition and tongue coating as risk factors for halitosis

A capacidade olfativa como instrumento de diagnóstico não deve ser ignorada por aqueles que trabalham na área da saúde. O objetivo do trabalho foi apresentar um modelo de avaliação organoléptica do odor bucal e avaliar a presença de gengivite, periodontite crônica e do biofilme lingual como indicadores de risco da halitose. Foram selecionados 120 indivíduos, de ambos os gêneros e na faixa etária de 18 a 66 anos, com as seguintes características: 60 portadores de halitose, com ou sem doença periodontal, e 60 indivíduos sem halitose, com ou sem doença periodontal. Todos foram submetidos às seguintes avaliações: teste organoléptico, anamnese e exame clínico para detectar a presença de biofilme lingual e alterações periodontais. O estudo mostrou que não houve associação entre os escores organolépticos e as alterações periodontais. O teste organoléptico positivo foi estatisticamente associado apenas à presença do biofilme lingual, podendo assim considerá-lo como um indicador de risco para as alterações do odor bucal (p = 0,0001). O modelo apresentado para a realização do teste organoléptico mostrou-se clinicamente viável, de execução fácil e rápida. Em resumo, os presentes achados mostraram que a presença de biofilme lingual pode ser considerado como um fator de risco para a halitose.

The aim of the present study was to evaluate the presence of gingivitis, chronic periodontitis and tongue coating as possible indicators for halitosis. A total of 120 subjects of both genders aging from 18 to 66 years wereselected and allocated in 2 groups: 60 subjects diagnosed with halitosis and 60 subjects without halitosis. All subjectswere submitted to the organoleptic test, anamnesis and clinical examination to assess the presence of tongue coatingand periodontal diseases. The results showed no association between organoleptic scores and periodontal diseases (p>0.05). However, tongue coating was a highly related to thepresence of halitosis (p=0.0001). In addition, the organoleptic test was considered to be an easy and rapid procedure to evaluate the presence of halitosis. In conclusion, tongue coating can be a risk factor for halitosis.

Dental anxiety and pain related to ART

Atraumatic Restorative Treatment (ART) is considered to be well accepted, both by children and by adult patients. The objective of this review is to present and discuss the evidence regarding the acceptability of ART, from the patient's perspective. Aspects related to dental anxiety/fear and pain/discomfort have been highlighted, to facilitate better understanding and use of the information available in the literature. CONCLUSIONS: The ART approach has been shown to cause less discomfort than other conventional approaches and is, therefore, considered a very promising "atraumatic" management approach for cavitated carious lesions in children, anxious adults and possibly, for dental-phobic patients.

Sugar-free chewing gum and dental caries: a systematic review

OBJECTIVE: To appraise existing evidence for a therapeutic / anti-cariogenic effect of sugar-free chewing gum for patients. METHOD: 9 English and 2 Portuguese databases were searched using English and Portuguese keywords. Relevant articles in English, German, Portuguese and Spanish were included for review. Trials were excluded on lack of randomisation, control group, blinding and baseline data, drop out rate >33 percent, no statistical adjustment of baseline differences and no assessment of clinically important outcomes. Reviews were excluded on lack of information, article selection criteria, search strategy followed, search keywords, searched databases or lack of study-by-study critique tables. In cases of multiple reports from the same study, the report covering the longest period was included. Two reviewers independently reviewed and assessed the quality of accepted articles. RESULTS: Thirty-nine articles were included for review. Thirty were excluded and 9 accepted. Of the 9 accepted, 2 trials of reasonable and good evidence value did not demonstrate any anti-cariogenic effect of sugar-free chewing gum. However, 7 articles, with 1 of strong, and 6 of good evidence value, demonstrated anti-cariogenic effects of chewing Sorbitol, Xylitol or Sorbitol/Xylitol gum. This effect can be ascribed to saliva stimulation through the chewing process, particularly when gum is used immediately after meals; the lack of sucrose and the inability of bacteria to metabolize polyols into acids. Conclusion: The evidence suggests that sugar-free chewing gum has a caries-reducing effect. Further well-designed randomised trials are needed to confirm these findings.
