Global panorama of ankyloglossia in newborns: a bibliometric analysis / Panorama global da anquiloglossia em recém-nascidos: uma análise bibliométrica

This study aims to understand the global panorama of ankyloglossia in newborns by means of a bibliometric analysis of scientific productions up to January 2023. A search was conducted with the terms "Newborn", "Ankyloglossia" and their synonyms in the Pubmed, Embase, Cochrane, Virtual Health Library, Web of Science and Scopus platforms. After removing duplicates and applying the eligibility criteria, 431 studies were included and imported into the VOSviwer software. The most cited keywords were "Surgery" (198) and "Breastfeeding" (151). Among the 49 countries surveyed, the United States published the most on the subject (107). The most relevant study in the studied portfolio was "Ankyloglossia: assessment, incidence, and effect of frenuloplasty on the breastfeeding dyad" by Ballard and collaborators. The journal "Pediatrics" obtained the highest number of citations (608) and year 2019 recorded the most articles about ankyloglossia in newborns (44). The findings of this study show that the topic linked to oral brakes has sparked a growing interest in the scientific community, and show the concern in unveiling the real impact of ankyloglossia on the infant's breastfeeding, as well as the need to seek a consensus in diagnosis regarding surgical indication.

O estudo mais relevante no portfólio estudado foi escrito por Ballard e colaboradores sob o título "Ankyloglossia: assessment, incidence, and effect of frenuloplasty on the breastfeeding dyad". A revista "Pediatrics" obteve o maior número de citações (608) e ano de 2019 registrou a maior quantidade de artigos sobre a anquiloglossia em recém-nascidos (44). Os achados deste estudo demonstram que a temática ligada aos freios orais tem despertado um interesse crescente na comunidade científica e evidenciam a preocupação em desvendar o impacto real da anquiloglossia na amamentação do bebê, assim como a necessidade de buscar um consenso no diagnóstico em relação à indicação cirúrgica.

CYP2D6 isoenzyme and ABCB1 gene polymorphisms associated with postoperative nausea and vomiting in women undergoing laparoscopic cholecystectomy: a randomized trial.

INTRODUCTION: Postoperative nausea and vomiting is still a common complication. Serotonin receptor antagonists are commonly used in clinical practice for antiemetic prophylaxis. Interindividual variations in drug response, including single nucleotide polymorphisms, are related to pharmacokinetic and pharmacodynamic changes in these drugs and may lead to a poor therapeutic response. This study aimed to evaluate the influence of CYP2D6 isoenzyme and ABCB1 gene polymorphisms on the frequency of postoperative nausea and vomiting with the use of ondansetron or palonosetron. METHODS: A randomized, double-blind clinical trial including 82 women aged 60 years or over undergoing laparoscopic cholecystectomy was conducted. Patients were randomized to receive either ondansetron or palonosetron for postoperative nausea and vomiting prophylaxis. DNA was extracted from saliva. Genetic polymorphisms were analyzed by real-time polymerase chain reaction. The following polymorphisms were analyzed: rs3892097 C/T, rs1128503 A/G, rs16947 A/G, rs1065852 A/G, rs1045642 A/G, rs2032582 C/A, and rs20325821 C/A. RESULTS: Overall, vomiting, and severe nausea occurred in 22.5% and 57.5% of patients, respectively. In the palonosetron group, patients with the GG genotype (rs16947 A/G) experienced more severe nausea (p = 0.043). In the ondansetron group, patients with the AA genotype (rs16947 A/G) presented mild nausea (p = 0.034), and those with the AA genotype (rs1065852 A/G) experienced more vomiting (p = 0.034). CONCLUSION: A low antiemetic response was observed with ondansetron in the presence of the AA genotype (rs16947 A/G) and the AA genotype (rs1065852 A/G), and a low therapeutic response was found with palonosetron in the presence of the GG genotype (rs16947 A/G) in laparoscopic cholecystectomy.

Genetic polymorphism in the tumour necrosis factor alpha gene (G-308A) is associated with persistent apical periodontitis in Brazilians.

AIM: To investigate if there was an association between genetic polymorphisms in tumour necrosis factor (TNF)-⍺ and its receptors TNFRSF1A and TNFRSF1B with persistent apical periodontitis (PAP) in Brazilian subjects. METHODOLOGY: Patients who had pulpal necrosis and apical periodontitis at the time of treatment, with at least 1-year of follow-up after non-surgical root canal treatment were recalled. Three hundred and seventy eight subjects were included, 150 subjects with signs/symptoms of PAP and 228 subjects with root canal-treated teeth exhibiting healthy perirradicular tissues (healed). Genomic DNA was extracted from saliva and used for TNF-⍺ (rs1800629), TNFRSF1A (rs1800693) and TNFRSF1B (rs1061622) genotyping by real-time PCR. Genotypes and alleles frequencies were evaluated by c2 or Fisher's exact tests and odds ratios were implemented (α = 5%). RESULTS: The genetic polymorphism in TNF-α (rs1800629) was associated as a protective factor for the development of PAP (p < .05), once subjects who presented at least one allele A (AA+AG X GG), had a higher chance to lesion repair (p < .05). The polymorphisms rs1800693 and rs1061622 in TNF receptors (TNFRSF1A and TNFRSF1B, respectively) were not associated with the development of PAP (p > .05). CONCLUSIONS: The observed results demonstrate that polymorphism in TNF-α but not in its receptors is associated with PAP.

Protocolo clínico-laboratorial para a confecção de protetor bucal personalizado ao alcance do clínico / Clinical-laboratory protocol for the manufacture of personalized mouthguard within the reach of the clinician

O procedimento de pulpectomia em dentes decíduos consiste na remoção total do tecido pulpar com inflamação irreversível ou com necrose, preparo químicomecânico e obturação com material reabsorvível, com o intuito de manter o dente o maior tempo possível na cavidade bucal, devolvendo função e saúde para o paciente infantil. Existem vários protocolos descritos na literatura, no entanto, não há consenso entre eles e poucos possuem acesso livre. Sendo assim, observa-se carência de um guia clínico e prático para nortear o cirurgião-dentista na realização desse procedimento durante o atendimento odontopediátrico. Portanto, o intuito deste trabalho é apresentar aos clínicos um protocolo de pulpectomia com altas frequências de sucesso clínico e radiográfico, baseado em evidências científicas, desenvolvido e aplicado pelo Grupo de Pesquisa de Endodontia em Odontopediatria da Universidade Federal do Rio de Janeiro (GEDOPED-UFRJ). O presente protocolo contempla indicações, contraindicações, tática operatória, materiais necessários e orientações para acompanhamento. Com esta publicação de maneira gratuita, de acesso livre e no idioma dominante do país, espera-se ampliar o alcance de odontopediatras e clínicos gerais que atendem crianças a um tratamento eficaz.

Pulpectomy in primary teeth consists of the complete removal of the irreversibly affected pulp or necrotic pulp tissue, chemical-mechanical preparation of the root dentin and filling root canals with a resorbable material, to keep the tooth as long as possible in the oral cavity, restoring function and health. There are several pulpectomy protocols described in the literature, however, there is no consensus among them and only few of them are open access. Therefore, there is a lack of clinical and practical guides to the practitioner in performing this procedure during pediatric dental care. The aim of this article is to present a clinically and radiographically successful pulpectomy protocol, based on scientific evidence, developed, and applied by the Research Group on Endodontics in Pediatric Dentistry at the Universidade Federal do Rio de Janeiro. This protocol includes indications, contraindications, operative techniques, materials, and guidelines for follow-up appointments. With this open access publication in Portuguese, we hope to disseminate an effective treatment and expand the outreach of a pulpectomy technique protocol to pediatric dentists and clinicians who treat children.

Assessment of oral health-related quality of life in adolescents, young adults, and adults with dental agenesis: A comparative study.

AIM: To detect the impact on oral health-related quality of life (OHRQoL) in adolescents, young adults, and adults with dental agenesis (DA). METHODS: A comparative study (1:2) matched for age and sex was designed. Data of participants, aged 14-55 years (group with DA: G1; group without DA: G2), and who answered the Brazilian version of the Oral Health Impact Profile-14 questionnaire, were collected. One-way analysis of variance and Student's t-test were applied, considering p <.05 to be significant. RESULTS: The final sample consisted of 90 participants (G1 = 30; G2 = 60), with a mean age of 28.76 (±10.87) years. The mean scores in the G1 and G2 groups were 5.30 ± 5.35 and 2.45 ± 3.95, respectively. Comparing the means of both groups, in terms of the total score (p = .01), psychological discomfort (p = .04), psychological disability (p = .01), and social disability (p = .04) showed statistical differences. Evaluating G1, the age did not influence the negative impact on OHRQoL. The variables, years of study (≥9), DA severity, and location of DA in the anterior and posterior regions negatively influenced OHRQoL in different domains (p <.05). CONCLUSION: Despite low OHRQoL, DA generated negative impact on OHRQoL in adolescents/young adults, and adults.

Oral health-related quality of life of 8-10 year-old children with traumatic dental injury

Introduction: Children presents high prevalence of traumatic dental injury (TDI). Objective: It is very important to detect the impact on oral health related to quality of life (OHRQoL) in this age group. Methods: Based on this, a cross sectional study was carried out using a convenience sample. Children from 8-10 years with TDI in permanent teeth were recruited over an 18 month period, from a public University. Data about OHRQoL using the Brazilian version of CPQ 8-10 (B-CPQ 8- 0 ) were collected. TDI were classified according to Andreasen criteria and grouped according to its severity. Variations in the scores and impact of TDI on OHRQoL according to age, gender and TDI severity were examined using nonparametric statistical tests (Kruskall-Wallis and Mann-Whitney test, p<0.05). Results: From a sample of 255 children, 41 healthy children that suffered TDI in permanent were included in the study. The mean B-CPQ 8-10 scores were 29.7 (SD 14.3). Emotional and social wellbeing domais had the highest negative score impact average 8.8 (SD 5.9) and 9.8 (SD 6.3), respectively. Gender or TDI severity did not present relation to impact on OHRQoL. In relation to age, 10-year-old children had more impact on their OHRQoL on the overall scale (p<0.05) and for the functional limitation subscale (p<0.05). Conclusion: TDI impacts negatively on OHRQoL of children aged from 8-10 years old.

Introdução: Crianças apresentam alta prevalência de traumatismo dentário (TD).Objetivo: Detectar o impacto do TD na qualidade de vida relacionada à saúde bucal (QVRSB) nessa faixa etária. Métodos: Um estudo transversal foi realizado com amostra de conveniência recrutando-se crianças de 8-10 anos com TD em dente permanente por um período de 18 meses em clínica pública. Dados sobre a QVRSB foram coletados através da versão brasileira do CPQ 8-10 (B-CPQ 8-10 ). O TD foi classificado de acordo com os critérios de Andreasen e agrupado de acordo com sua gravidade. As variações nos escores e o impacto do TD na QVRSB, de acordo com idade, gênero e gravidade do TD foram examinados por meio de testes estatísticos não paramétricos (teste de Kruskall-Wallis e Mann-Whitney, p <0,05). Resultados: De uma amostra de 255 crianças, 41 crianças saudáveis que sofreram TD em dentes permanentes foram incluídas no estudo. O escore médio do B-CPQ 8-10 foi 29,7 (DP 14,3). Os domínios bem-estar emocional e social apresentaram maior impacto negativo com média de 8,8 (DP 5,9) e 9,8 (DP 6,3), respectivamente. A diferença de gênero e a gravidade do TD não apresentaram relação de impacto na QVRSB. Em relação a idade, crianças de 10 anos tiveram maior impacto na escala global da QVRSB (p <0,05) e na subescala de limitação funcional (p <0,05). Conclusão: O TD impacta negativamente a QVRSB de crianças de 8 a 10 anos de idade.

Condição de saúde oral e indicativos da síndrome de Burnout em estudantes de Odontologia sedentários e atletas / Condition of oral health and Burnout syndrome indicatives in sedentary and athlete Dental students

O estudo objetivou comparar a condição de saúde oral e os indicativos de síndrome de Burnout em estudantes de Odontologia sedentários e atletas. Após aprovação do projeto pelo Comitê de Ética em Pesquisa, foi selecionada, por conveniência, uma amostra não probabilística de estudantes do terceiro ano do Curso de Odontologia de uma Universidade Federal brasileira com características semelhantes quanto ao sexo, idade, escolaridade e nível socioeconômico, para compor dois grupos independentes: 1) atletas e 2) sedentários. Para as estimativas da condição de saúde oral foram realizadas avaliação periodontal completa, levantamento de dados de um questionário elaborado a partir de uma ferramenta validada, o Maslach Burnout Inventory-General Survey (MBI), preenchimento de prontuário de paciente e radiografia panorâmica. Os dados coletados foram analisados estatisticamente pelo teste T ou Mann-Whitney, análise de regressão logística simples e correlação de Pearson (significância em 5%, α =0,05). Houve variações na condição de saúde oral de estudantes de Odontologia atletas em relação aos sedentários quanto ao sangramento à sondagem, a profundidade de sondagem e achados radiográficos, que apresentaram variações estatisticamente significativas (p<0,05) com piores resultados para o grupo de sedentários. O sangramento à sondagem foi o principal indicativo da discrepância que apresentou correlação fraca (ρ=0,31) com a exaustão emocional, que é a medida do sentimento de estar emocionalmente sobrecarregado e esgotado. Os estudantes sedentários são mais sensíveis a problemas e tensões desencadeados no ambiente acadêmico, com maior propensão a instalação de danos somáticos como os problemas orais (AU).

The study aimed to compare the oral health condition and the Burnout syndrome indicatives of athete and sedentary dental students. After the approval of the project by the research ethics committee a non-probabilistic sample of convenience, with students of third year of dentistry course of a Brazilian Federal University with similar characteristics in relation to sex, age, schooling and socioeconomic level were selected. They composed two independent groups: 1) Atheletes and 2) Sedentaries. For health estimations were performed a periodontal evaluation and data collections from a questionnaire on the basis of a validated tool, the Maslach Burnout Inventory-General Survey (MBI), a medical records and a panoramic radiograph. All data were statistically analyzed by T-test, Mann-Whitney test, simple logistic regression analysis and Pearson's correlation (significance at 5%, α = 0.05). There were variations in the oral health condition between the athelete and sedentary dental students for bleeding on probe, probe depth and radiographic findings that statistically differed (p<0.05) showing worst results for the sedentary group. The bleeding on probe was the main indicator of the discrepancy and presented a weak correlation (ρ = 0.31) with an emotional exhaustion, which measures feelings of being emotionally overextended and exhausted. Sedentary dental students are more sensitive to problems and tensions triggered in the academic environment with a greater propensity to instalation of somatic injuries such as oral problems (AU).

Effect of the antimicrobial photodynamic therapy on microorganism reduction in deep caries lesions: a systematic review and meta-analysis.

This study aimed to perform a systematic review to assess the effectiveness of antimicrobial photodynamic therapy (aPDT) in the reduction of microorganisms in deep carious lesions. An electronic search was conducted in Pubmed, Web of Science, Scopus, Lilacs, and Cochrane Library, followed by a manual search. The MeSH terms, MeSH synonyms, related terms, and free terms were used in the search. As eligibility criteria, only clinical studies were included. Initially, 227 articles were identified in the electronic search, and 152 studies remained after analysis and exclusion of the duplicated studies; 6 remained after application of the eligibility criteria; and 3 additional studies were found in the manual search. After access to the full articles, three were excluded, leaving six for evaluation by the criteria of the Cochrane Collaboration's tool for assessing risk of bias. Of these, five had some risk of punctuated bias. All results from the selected studies showed a significant reduction of microorganisms in deep carious lesions for both primary and permanent teeth. The meta-analysis demonstrated a significant reduction in microorganism counts in all analyses (p<0.00001). Based on these findings, there is scientific evidence emphasizing the effectiveness of aPDT in reducing microorganisms in deep carious lesions.

Perfil Epidemiológico dos Traumatismos Dentários em Crianças e Adolescentes no Brasil / Epidemiological Profile of Dental Trauma in Children and Adolescents in Brazil

O traumatismo dentário - TD é considerado, pela Organização Mundial de Saúde ? OMS um problema de saúde pública que apresenta alta prevalência e gera impacto negativo na qualidade de vida relacionada à saúde bucal de crianças/adolescentes e familiares com sequelas biológicas, socioeconômicas, psicológicas e comportamentais. Assim, o presente estudo objetivou realizar uma revisão critica da literatura sobre os estudos que avaliam o perfil epidemiológico do TD em crianças e adolescentes, mapeando a distribuição desses estudos no Brasil. A busca na literatura foi feita utilizando os descritores: traumatismos dentários, criança, adolescente, e epidemiologia, nas Bases Medline, Lilacs, SciELO, BBO e no Google Acadêmico. Os mesmos termos em inglês foram utilizados no Pubmed. De 248 artigos encontrados inicialmente, foram removidas as duplicatas e aplicados os critérios de inclusão e exclusão, selecionando-se 53 artigos. Observou-se que há muitos estudos sobre a prevalência dos TD desenvolvidos no Brasil durante os últimos anos. No entanto, os estudos estão concentrados em algumas regiões específicas como Rio Grande do Sul, Santa Catarina, Minas Gerais e São Paulo. A prevalência de TD em dentição decídua foi de 9,4% e 62,1%, e permanente variou de 8,0% a 58,6%. Os fatores como gênero, sobressaliência acentuada e cobertura labial inadequada foram frequentemente associados ao TD em crianças e adolescentes. Baseado nos levantamentos epidemiológicos dos artigos selecionados neste trabalho, conclui-se que, devido à concentração das pesquisas em alguns centros, não há um perfil representativo da população brasileira e os dados compilados dos estudos devem ser comparados com cautela, devido à grande diferença metodológica existente nos estudos.

Traumatic dental injury (TDI) is considered by the World Health Organization as a public health problem with high prevalence, which generates negative impact on oral health related to quality of life of children / adolescents and their families, causing biological, socioeconomic, psychological and behavioral sequelae. The present study aimed to conduct a critical review of the literature on studies assessing the epidemiological profile of the TDI in children and adolescents, mapping the distribution of these studies in Brazil. The search was performed using the descriptors ?dental trauma, children, adolescents, epidemiology and Brazil?, in the Medline, Lilacs, SCiELO, BBO, Google Scholar, and Pubmed. Initially, 248 articles were found. After removing the duplicates and applying the inclusion and exclusion criteria, 53 articles were selected. It has been observed that there are many studies of prevalence of TDI developed in recent years in Brazil. However, these studies are concentrated in some specific areas such as Rio Grande do Sul, Santa Catarina, Minas Gerais, and São Paulo. The prevalence of TDI in the primary dentition was 9.4% and 62.1%, ranging from 8.0% to 58.6% in the permanent dentition. Factors such as gender, increased overjet and inadequate lip coverage were often associated with TDI in children and adolescents. Based on the epidemiological surveys of the articles selected in this study, we concluded that there is no representative profile of the Brazilian population due to the concentration of research in some centers, thus data should be compared with caution due to the large methodological difference between the studies.

Avaliação da Relação Causal Entre a Presença de Hábitos Bucais Deletérios, Tipo de Aleitamento e Maloclusões em Crianças na Dentadura Decídua / Causal Relationship between the Oral Habits, Feeding and Malocclusion in Children Deciduous Teeth

As maloclusões, por seu alto índice de prevalência, vêm sendo consideradas um problema de saúde pública. A literatura ressalta a importânciado aleitamento natural para a prevenção de hábitos bucais e maloclusão. O objetivo do estudo foi avaliar a relação das formas de aleitamentocom hábitos bucais deletérios e seu efeito sobre a oclusão na dentição decídua. Um estudo transversal, retrospectivo, foi realizado em 443crianças de 2 a 6 anos de 27 creches públicas de Nova Friburgo, RJ. Os dados foram coletados através de questionários para pais/responsáveis arespeito do tipo de aleitamento e hábitos bucais deletérios. O exame de oclusão foi realizado por 2 examinadores (kappa=0,80). Os dados foramtabulados e analisados, sendo obtida a frequência e a associação das variáveis (Teste qui-quadrado e ODDS Ratio). Foi observado associaçãodo tipo de aleitamento com os seguintes hábitos: sucção de chupeta (OR 0,12 IC 0,05-0,32; p<0,01) e sucção digital (OR 0,35 IC 0,11-1,13;p=0,04), bem como com as seguintes maloclusões: mordida aberta anterior (OR 0,15 IC 0,06-0,41; p<0,01), mordida cruzada posterior (OR0,26 IC 0,05-1,23; p=0,04) e sobressaliência acentuada (OR 0,32 IC 0,09-1,12; p=0,03). Na população estudada, o aleitamento artificial estáassociado ao hábito de sucção de chupeta, sucção digital e maloclusões, destacando-se a mordida aberta anterior, mordida cruzada posterior esobressaliência acentuada. Diante disso é desejável a implementação de programas preventivos de incentivo ao aleitamento natural para essapopulação.

Malocclusions have been considered as a public health problem due to their high prevalence rate. Literature highlights the importance ofbreastfeeding for prevention of oral habits and malocclusion. This study aimed to evaluate the relationship of breastfeeding and harmful oralhabits and effects on deciduous oclusion. A retrospective cross-sectional study was conducted in 443 children aged 2 to 6 years of 27 publickindergartens in Nova Friburgo, RJ. Data were collected through questionnaires to parents/guardians about the type of feeding and oral habits. Occlusal examination was performed by two examiners (kappa=0.80). Data were tabulated and the relationship between the variables was analyzed (chi-square test and odds ratio). It was observed association of type of breastfeeding with the following habits: pacifier sucking (OR 0.12 CI 0.05 to 0.32, p < 0.01 ) and thumb sucking (OR 0.35 CI 0.11 ? 1.13 , p = 0.04) and with the following malocclusions: anterior openbite (OR 0.15 CI 0.06 to 0.41, p < 0.01 ), posterior crossbite (OR 0.26 CI 0.05 to 1.23 , p=0.04 ) and deep overjet (OR 0.32 CI 0.09 to 1.12,p=0.03). In the population studied, artificial breastfeeding is associated with harmful oral habit such as pacifier sucking thumb sucking, andmalocclusions as anterior open bite, posterior crossbite and severe overjet. So, it is desirable to implement preventive programs to encouragebreastfeeding in this population.

O uso do protetor bucal nas artes marciais: consciência e atitude / Mouthguard use in martial arts: awareness and attitude / El uso del protector bucal en las artes marciales: conciencia y actitud

Introdução: O uso de protetores bucais durante a prática de esportes de contato é de fundamental importância como medida preventiva dos traumatismos orofaciais. Objetivo: Realizar um levantamento quanto a utilização do protetor bucal entre praticantes de artes marciais, assim como verificar qual é a percepção que tais esportistas têm sobre sua importância e função. Métodos: Realizou-se uma pesquisa descritiva e transversal, de caráter investigativo, composta por 231 praticantes de três diferentes modalidades de artes marciais: Jiu-jítsu, Tae kwon do e Muay Thai, nas cidades de Nova Friburgo-RJ e Macaé-RJ, Brasil, por meio de um questionário estruturado. Os dados foram tabulados no programa estatístico SPSS 16.0. Foi realizada a frequência, sendo aplicado, ainda, o teste qui-quadrado (p<0,05), para estabelecer relação entre variáveis de interesse. Resultados: Os dados indicaram que 60,6% dos entrevistados nunca receberam informações sobre o traumatismo orofacial durante a prática esportiva e que 46,3% dos esportistas já sofreram algum tipo de traumatismo orofacial. A maioria dos atletas (93,9%) considera importante o uso do protetor bucal, porém este dado é desproporcional ao percentual de usuários do dispositivo: 78,7% no Muay Thai, 60,9% no Jiu-jítsu e 47,5% no Tae kwon do (p< 0,01). Dos protetores bucais existentes no mercado, o mais utilizado é o termoplástico ou tipo II (52,5%) em todas as modalidades de lutas avaliadas. O protetor bucal personalizado causou menor percentual de interferência no rendimento durante a prática esportiva quando comparado com os outros tipos de protetores (p<0,07).

Introduction: The use of mouthguard during contact sports is crucial for preventing orofacial trauma. Objective: To conduct a survey regarding the use of mouthguards among martial arts practitioners as well as find what is the perception that these athletes have about its importance and function. Method: A descriptive cross-sectional survey of investigative character was conducted with 231 practitioners of three different kinds of martial arts (Brazilian Jiu-Jitsu, Muay Thai and Tae Kwon Do) in the cities of Nova Friburgo and Macaé, in Rio de Janeiro, Brazil, through a structured questionnaire. The data was analyzed in the SPSS 16.0 statistical software. The frequency was obtained and the Chi-square Test applied (p<0.05) to establish association among variables of interest. Results: The data indicated that 60.6% of the respondents had never received information about orofacial trauma during sports practice and that 46.3% of the athletes have suffered some sort of orofacial injury. Most athletes (93.9%) consider important to use the mouth guard, but this datum is disproportionate to the percentage of users of the device: 78.7% in Muay Thai, 60.9% in Jiu-Jitsu and 47.5% in Tae Kwon Do (p<0.01). Among the mouthguards on the market, the most widely used is the thermoplastic or type II (52.5%) in all forms of wrestling evaluated. The custom mouthguard caused the lowest percentage of interference of performance during sports practice when compared with other protective devices (p<0.07). Conclusion: Most athletes recognize the importance of using a mouthguard, although they reported not having received information about orofacial trauma during sports practice; most athletes use thermoplastic mouthguard; it is necessary to disseminate information about the benefits of using custom mouthguard (type III) as well as encourage the use of this particular type by all practitioners of martial arts. .

Aesthetic solution to fluorosis in a child / Solução estética para a fluorose em criança

Dental fluorosis is a defect of enamel formation caused by chronic ingestion of fluoride from different sources during tooth development, which results in interference in proper mineralization. Clinically the tooth enamel may present as white striae along the lines of enamel, opaque white spot and in more severe cases as brown spots. Diagnosis is based on clinical characteristics associated with a history of exposure to fluoride. The aim of this report is to present a treatment in a child with severe aesthetic compromising in anterior maxillary permanent teeth caused by fluorosis. The treatment was based on a combination of three techniques in order to be minimally invasive, enhance aesthetics and preserving the dental structure

Fluorose dental é um defeito na formação do esmalte causado pela ingestão crônica de flúor de diferentes origens durante o desenvolvimento dentário, o que resulta em uma interferência na mineralização adequada. Clinicamente, o esmalte dentário pode assumir uma tonalidade esbranquiçada ou exibir pequenas manchas ou linhas brancas e, nos casos mais severos, manchas amarronzadas. O diagnóstico é baseado em características clínicas associadas com a história de exposição ao flúor. O foco deste estudo é mostrar o tratamento em uma criança com grande comprometimento estético em dentes permanentes anteriores superiores acometidos por fluorose. O tratamento baseou-se numa combinação de três técnicas, a fim de ser minimamente invasiva, melhorar a estética e preservar a estrutura dentária

Os dados foram analisados descritivamente e utilizando o teste Exato de Fisher (p<0,05). Embora os responsáveis tenham poucas informações sobre os métodos alternativos de remoção de cárie, eles são receptivos ao uso dos mesmos em seus filhos.

The purpose this article is to evaluate the caregivers'perception of predictors of dental fear and acceptance of use a new technology for removal of caries in their children. Interview using a semi-structured questionnaire with 105 caregivers for children 2 to 12 years attending at Clinic of Pediatric Dentistry. The data were about dental fear/ apprehension; knowledge and importance of new studies and permission to use new technologies. Data were analyzed descriptive and using the Fisher’s Exact test (p <0.05). A lthough t he c aregivers have little information about alternative methods of caries removal, they are receptive to use them in their children.

TGFB3 and BMP4 polymorphism are associated with isolated tooth agenesis.

OBJECTIVE: To evaluate the association of the polymorphisms in the TGFB3 gene (rs2268626) and the BMP4 gene (rs17563) with isolated human tooth agenesis. MATERIALS AND METHODS: One hundred and seventy-five unrelated individuals (125 control individuals without tooth agenesis and 50 cases with tooth agenesis) were evaluated using a case-control design. The participants of the study were recruited through the Dental School of the Federal University of Rio de Janeiro, Brazil. Genotyping of the selected polymorphisms for TGFB3 (48 individuals with tooth agenesis and 125 control cases) and BMP4 (46 individuals with tooth agenesis and 88 control cases) were carried out by real-time PCR using the Taqman assay method from a genomic DNA isolated from buccal epithelial cells of all individuals. RESULTS: Significant statistical differences were found for genotype frequencies between tooth agenesis and TGFB3 control samples (p = 0.026). In addition, significant differences were also observed for allele and genotype frequencies between unilateral tooth agenesis and TGFB3 control samples (p = 0.014 and 0.004 for allele and genotype frequencies, respectively). For BMP4, genotype distribution had a statistically significant difference between groups (p = 0.047). The GG genotype of BMP4 was more frequent in individuals with three or more missing teeth than in the control group (p < 0.0001). CONCLUSIONS: These results indicate that polymorphisms in the TGFB3 gene and in BMP4 genes contribute to tooth agenesis. Nonetheless, the extents to which this polymorphism may actually contribute to the tooth agenesis status should be clarified.

Topography and presence of a smear layer in deciduous molars prepared with high-speed cutting and ultrasonic abrasion: an in-vitro study.

OBJECTIVE: The aim of this in-vitro study was to compare the effect of high-speed cutting (HS) with ultrasonic abrasion (US) concerning the internal topography and the presence of a smear layer in a cavity preparation performed in healthy deciduous molars. MATERIAL AND METHODS: Seven first deciduous molars were used. Two occlusal cavity preparation were done, one in the medial fossula and another in the distal fossula, which were chosen randomly. One preparation was carried out with a diamond point adapted to the HS system (GI), while a chemical vapor deposition (CVD) point adapted to a US device (GII) was used for the other preparation. Subsequently, all samples (n = 14) were cleaved to observe the inside and then prepared for evaluation using scanning electron photomicroscopy. The internal topography of the prepared cavities was descriptively analyzed. In order to assess the presence of a smear layer, scores were tabulated using the 2000 GMC program and analyzed using the Mann-Whitney test. RESULTS: Concerning the internal topography, the presence of striae was verified in both groups. In the GI group they were finer, found in a greater number, and with narrower spaces between them. In the GII group, the striae were undulating, similar to the effect of wheels on sand, and with wider spaces between them. As regards the presence of a smear layer, there was no statistically significant difference between the groups (P > 0.05). CONCLUSIONS: In view of the methodology employed, it may be concluded that cavity preparation with a CVD point in a US abrasion system led to the formation of fewer striae and both devices promoted the marked presence of a smear layer, obstructing dentinal tubuli.

[Breast-feeding as a source of prevention in healthcare]. / Amamentação natural como fonte de prevenção em saúde.

The importance of breast-feeding has been addressed through multi-professional approaches. As healthcare practitioners, dentists are included in this context and - due to the close links between breast-feeding and the development of the stomatognathic system - should be able to advise pregnant women and new mothers on this practice, with countless benefits for mothers and their babies. This paper thus presents up-to-date and enlightened information through a review of the literature that supports the benefits of breast-feeding, urging heightened awareness of its importance and the preparation of policies and actions implemented through Brazil's National Health System (SUS) that rank breast-feeding as a high-priority goal.

Amamentação natural como fonte de prevenção em saúde / Breast-feeding as a source of prevention in healthcare

A importância da amamentação natural tem sido abordada sob âmbito multiprofissional. O cirurgião dentista como profissional da área de saúde está incluído neste contexto e deve ser capaz de orientar a gestante e as recém-mães visto a forte relação que existe entre amamentação natural e o desenvolvimento do sistema estomatognático. São inúmeros os benefícios gerados tanto para a mãe quanto para o bebê. Baseado nisso, o presente artigo propõe, por meio de uma revisão de literatura discutida, argumentar com informações atuais e esclarecedoras os benefícios da amamentação dando estímulo à conscientização da sua importância e à formulação de políticas e ações, através do SUS, que priorizem a prática da amamentação como meta.

Educative practices and attitudes within the pre-school environment: evaluating the education professionals.

School and family together play an important role in the individual development of children. Therefore, this study aimed at evaluating the practices and attitudes towards oral health care of 245 education professionals working in 24 public municipal pre-schools in Niterói, State of Rio de Janeiro, Brazil. The data were obtained from self-questionnaires consisting of both open and closed questions. The methodology was both quantitative and qualitative, and the quantitative analysis was based on frequency (%). Regarding oral health practices, it was observed that the majority of the education professionals emphasized toothbrushing as a vital method of oral hygiene. In addition, 70.7% of the education professionals performed other types of oral hygiene activities with the schoolchildren, and 17.1% did so with the children's families. All the participants of the study considered that education professionals have a key role in promoting healthy oral habits amongst the schoolchildren and they believe that involving the dentist in educative programs is important. It was therefore concluded that the education professionals surveyed have positive practices and attitudes regarding the children's care, and they recognize their role in fostering healthy habits and developing integrated pedagogic oral health programs.

Conhecimentos, práticas e atitudes de responsáveis frente à saúde bucal do pré-escolar / Knowledge, pratical and attitudes of responsible in relation to the buccal health of the children

O objetivo deste estudo foi avaliar os conhecimentos, as práticas e as atitudes de responsáveis por pré-escolares sobre saúde bucal, de uma Unidade de Educação Infantil em Niterói, RJ. A amostra foi composta por 40 indivíduos, entrevistados com o auxílio de um formulário semi-estruturado para a coleta dos dados. A metodologia utilizada foi do tipo quanti-qualitativa, sendo que a análise descrita foi obtida pela frequência (%) através do programa estatístico SPSS 11.0. Dentre os principais resultados, observou-se que 82,5% receberam informação sobre saúde bucal, sendo a escola a mais citada; 82,5% dos responsáveis auto-avaliaram seu conhecimento como bom e razoável; no entanto, 42,5% não sabiam o nome de qualquer doença que ocorre na boca e apenas 40% dos responsáveis escovavam os dentes da criança. Embora 77,5% dos responsáveis tenham afirmado que os alimentos influenciam a saúde bucal, o açúcar foi altamente consumido pelas crianças. Concluiu-se que embora os responsáveis tenham demonstrado atitudes positivas em relação à saúde bucal, seus conhecimentos e práticas se mostraram limitados e não corresponderam a sua auto-avaliação, havendo a necessidade da criação de programas educativos em saúde bucal para que estes possam atuar como multiplicadores do saber em benefício da criança.

The aim of this study was to evaluate the knowledge, practical and the attitudes of responsible for childrens on buccal health, of a Unit of Infantile Education in Niterói, RJ. The sample was composed for 40 people, interviewed with a form half-structuralized for the collection of the data. The used methodology was of the quanti-qualitative type, being that the descriptive analysis was gotten by the frequency (%) through statistical program SPSS 11.0. It was observed that 82,5% had received information on buccal health, being the most cited school; 82,5% auto-had evaluated its knowledge as good or reasonable; hawevwe, 42.5% didn't know the name of any illness that occurs in the mouth and only 40% brushed teeth of the child. Although 77.5% of the people had affirmed that the foods influence the buccal health, the sugar was highly consumed by the children. It was concluded that even so the interviewed have demonstrated positive attitudes in relation to the buccal health, its practical and knowledge had shown limited and they had not corresponded its auto-evaluation, having the necessity of the creation of educative programs in buccal health so that these can act as multiplying of knowing in benefit of the child.
