Treatment of dehiscence-type defects with collagen matrix and/or enamel matrix derivative: Histomorphometric study in minipigs.

BACKGROUND: This study aimed to evaluate, histomorphometrically, the use of collagen matrix (CM) and/or enamel matrix derivative (EMD) for the treatment of dehiscence-type recession defects in minipigs. METHODS: Eight healthy, male, young BR-1 minipigs, with no periodontal disease were treated. Bilateral dehiscence-type defects were surgically created on the buccal of the mandibular premolars (PI and PII). After 30 days, the defects were randomly assigned to four groups: coronally advanced flap (CAF); CAF + CM; CAF + EMD; and CAF + CM + EMD (split-mouth design). The evaluated parameters (mm): total defect length; new cementum (NC); new bone (NB); gingival margin position; total epithelium length; epithelium on the root; connective tissue adaptation; and soft tissue thickness (STT). RESULTS: The EMD-treated groups showed a superior length of NC [4.13 ± 1.22 (CAF + EMD); 3.95 ± 1.11 (CAF + CM + EMD); 2.94 ± 0.77 (CAF + CM); 2.72 ± 0.81 (CAF), P = 0.02] and NB [3.21 ± 0.68 (CAF + CM + EMD); 3.01 ± 0.56 (CAF + EMD); 2.15 ± 0.47 (CAF + CM); 2.29 ± 0.82 (CAF), P = 0.005]. The CAF and CAF + CM groups showed a superior epithelial length when compared to EMD-treated groups after 3 months. A superior STT was observed for CAF + CM + EMD group (1.5 ± 0.33) when compared with the other groups [1.09 ± 0.26 (CAF + EMD); 1.04 ± 0.34 (CAF + CM); and 1.14 ± 0.29 (CAF), P = 0.03]. CONCLUSION(S): The results of the present study indicate that EMD application, irrespective of the combination with CM, may improve the periodontal regeneration of dehiscence-type defects in this animal model.

Does enamel matrix derivative application improve clinical outcomes after semilunar flap surgery? A randomized clinical trial.

OBJECTIVES: To evaluate the treatment of gingival recessions by semilunar coronally positioned flap plus enamel matrix derivative (SCPF + EMD). MATERIALS AND METHODS: Thirty patients with class I localized gingival recession were included. They were randomly allocated in two groups: SCPF + EMD and SCPF. Recession height (RH), recession width (RW), width of keratinized tissue (WKT), thickness of keratinized tissue (TKT), probing depth (PD), and clinical attachment level (CAL) were measured at baseline, 6 and 12 months post-surgery. Patient/professional evaluation of esthetics and root sensitivity was performed. RESULTS: After 12 months, mean root coverage was 1.98 ± 0.33 mm for SCPF + EMD (90.86 ± 14.69%) and 1.85 ± 0.41 mm (79.76 ± 17.44%) for SCPF (p > 0.05). The esthetic evaluation by the patient showed preference for SCPF + EMD. According to the professional evaluation (QCE), the use of EMD decreases the appearance of postoperative scar tissue line. There was a significant reduction in root hypersensitivity with no further complaints by the patients. CONCLUSIONS: The addition of EMD provides significantly better esthetics to SCPF, according to patient and professional assessments. SCPF + EMD is effective but not superior to SCPF for root coverage, after 12 months. CLINICAL RELEVANCE: Previous clinical trials showed that the combination of EMD with coronally advanced flaps may enhance the outcome of root coverage. There is a lack of studies testing the combination of EMD with SCPF. The combination SCPF + EMD provides better esthetics when compared to the SCPF and is effective, but not superior, to SCPF for root coverage, after 12 months. TRIAL REGISTRATION: NCT02459704.

Salivary levels of SIgA and perceived stress among dental students / Imunoglobulina A salivar e fatores de estresse em estudantes de odontologia

Background: Academic stress may impair mucosal immunity and expose dental students to an increased risk of infections. Objective: to assess stress scores in dental students and their relationship with variation in SIgA levels. Methods: All students (n = 289) were invited to take part of the study, and 207 (71.63%) effectively participated, being 152 (73.4%) females. At the day of data collection, the students answered The Dental Environmental Stress Questionnaire (DES) and unstimulated saliva samples were collected for determination of salivary flow rate and SIgA concentration and secretion rate. Results: Mean DES scores were higher in females (78.97 ± 16.42), but no correlations between the sum of DES scores and salivary parameters were observed (P=0.08). A moderate inverse relationship was observed between SIgA secretion rates and the subscales Academic Performance (P=0.01), Interpersonal relationships (P=0.02) and Difficulties and Insecurities about Professional Future (P=0.05). A weak correlation was found between SIgA concentration and the items Amount of assigned classwork (P=0.02), Lack of confidence in self to be a successful dentist (P=0.01), Lack of time for relaxation (P=0.01), Financial responsibilities (P=0.02) and Personal physical health (P=0.005). Weak correlations between SIgA secretion rates and DES items were also found for Lack of cooperation by patient in their home care (P=0.003), Patients being late or not showing up for their appointments (P=0.02), Lack of self confidence to be a successful dentist (P=0.008), Personal physical health (P=0.019), and others. Conclusion: Different sources of stress were observed among first to fifth year students and some of these stressors may negatively impact on salivary SIgA secretion. (AU)

Introdução: o estresse acadêmico pode prejudicar a imunidade das mucosas e expor os estudantes de odontologia a um maior risco de infecções. Este estudo teve como objetivo avaliar os fatores de estresse em estudantes de odontologia e sua relação com a variação nos níveis de SIgA. Metodologia: Todos os alunos (n = 289) foram convidados a fazer parte do estudo, dos quais 207 (71,63%) participaram efetivamente, sendo 152 (73,4%) do sexo feminino. No dia da coleta de dados, os alunos responderam ao Questionário de Estresse no Ambiente Odontológico (DES) e foram coletadas amostras de saliva não estimuladas para determinação da taxa de fluxo salivar, da concentração de SIgA e da taxa de secreção. Resultados: os escores do DES foram maiores no gênero feminino (78,97 ± 16,42), mas não foram observadas correlações entre a soma dos escores DES e os parâmetros salivares (P = 0,08). Observou-se uma relação inversa moderada entre as taxas de secreção de SIgA e as subescalas Desempenho Acadêmico (P = 0,01), Relações Interpessoais (P = 0,02) e Insegurança em relação ao futuro profissional (P = 0,05). Uma correlação fraca foi encontrada entre a concentração de SIgA e os itens quantidade de trabalho exigido em sala de aula (P = 0,02), falta de autoconfiança para ser um dentista de sucesso (P = 0,01), falta de tempo para relaxar ou para lazer (P = 0,01), responsabilidades financeiras (P = 0,02) e saúde física pessoal (P = 0,005). Também foram encontradas correlações fracas entre as taxas de secreção de SIgA e os itens DES para falta de cooperação por parte do paciente em seus cuidados (P = 0,003), Atraso ou falta de pacientes nas consultas (P = 0,02), falta de autoconfiança para ser um dentista bem sucedido (P = 0,008), saúde física pessoal (P = 0,019) e outros. Conclusão: diferentes fontes de estresse foram observadas entre os estudantes do primeiro ao quinto ano e alguns desses fatores podem afetar negativamente a secreção de SIgA. (AU)

Recessões gengivais associadas a lesões cervicais não cariosas: uma revisão sobre o tratamento multidisciplinar / Gingival recessions associated with non-carious cervical lesions: a review on the multidisciplinary treatment

Frequentemente, as recessões gengivais (RG) estão associadas a lesões cervicais não cariosas (LCNC), defi nidas como a perda de estrutura dentária ao longo da margem gengival do dente, com a distinta característica de presença de tecido duro mineralizado em contraste com o tecido carioso. A partir de um ponto de vista topográfi co, a LCNC pode envolver apenas a coroa do dente (esmalte e/ou dentina coronal) ou somente a superfície radicular (cemento e/ou dentina radicular), ou pode localizar-se tanto na coroa como na raiz exposta. As principais indicações para o tratamento da LCNC são: 1) estética; 2) hipersensibilidade dentinária; 3) desenvolvimento de cáries; 4) acúmulo de biofi lme. Os procedimentos envolvem o tratamento restaurador e/ou cirúrgico, a depender do tipo de LCNC. Quando a LCNC atinge apenas a coroa do dente, o tratamento restaurador é mais indicado, enquanto uma lesão confi nada à raiz pode ser tratada preferencialmente com cirurgia plástica periodontal. Porém, a realidade clínica é geralmente complexa, o que torna o tratamento combinado mais favorável para certos casos. Portanto, o objetivo desse artigo foi realizar uma revisão da literatura concernente ao tratamento de recessões gengivais associadas a lesões cervicais não cariosas.

Often, gingival recessions (GR) are associated with non-carious cervical lesions (NCCL), defi ned as the loss of tooth structure along the gingival margin of the tooth, with the distinctive feature of the presence of mineralized hard tissue, in contrast to the carious tissue. From a topographical point of view, NCCL may involve only the tooth crown (enamel and/or coronal dentin) or only the root surface (cementum and/or radicular dentin) or can be located both in the crown and exposed root. The main indications for the treatment of NCCL are: 1) aesthetic; 2) dentine hypersensitivity; 3) development of caries; 4) biofi lm formation. The procedures involve restorative treatment and/or surgery depending on the type of NCCL. When NCCL is located exclusively at the tooth crown, the restorative treatment is best suited while a lesion located at the root surface should be treated preferably with periodontal plastic surgery. However, clinical reality is often complex, which makes the combination treatment more favorable for some cases. Therefore, the aim of this article is to review the literature concerning the treatment of gingival recession associated with non-carious cervical lesions.

Xenogenous Collagen Matrix and/or Enamel Matrix Derivative for Treatment of Localized Gingival Recessions: A Randomized Clinical Trial. Part II: Patient-Reported Outcomes.

BACKGROUND: Gingival recession (GR) might be associated with patient discomfort due to cervical dentin hypersensitivity (CDH) and esthetic dissatisfaction. The aim is to evaluate the effect of root coverage procedure with a xenogenous collagen matrix (CM) and/or enamel matrix derivative (EMD) in combination with a coronally advanced flap (CAF) on CDH, esthetics, and oral health-related quality of life (OHRQoL) of patients with GR. METHODS: Sixty-eight participants with single Miller Class I/II GRs were treated with CAF (n = 17), CAF + CM (n = 17), CAF + EMD (n = 17), and CAF + CM + EMD (n = 17). CDH was assessed by evaporative stimuli using a visual analog scale (VAS) and a Schiff scale. Esthetics outcome was assessed with VAS and the Questionnaire of Oral Esthetic Satisfaction. Oral Health Impact Profile-14 (OHIP-14) questionnaire was used to assess OHRQoL. All parameters were evaluated at baseline and after 6 months. RESULTS: Intragroup analysis showed statistically significant reduction in CDH and esthetic dissatisfaction with no intergroup significant differences (P >0.05). The impact of oral health on QoL after 6 months was significant for CAF + CM, CAF + EMD, and CAF + CM + EMD (P <0.05). Total OHIP-14 score and psychologic discomfort, psychologic disability, social disability, and handicap dimensions showed negative correlation with esthetics. OHIP-14 physical pain dimension had positive correlation with CDH (P <0.05). OHIP-14 showed no correlation with percentage of root coverage, keratinized tissue width, or keratinized tissue thickness (P >0.05). CONCLUSION: Root coverage procedures improve patient OHRQoL by impacting on a wide range of dimensions, perceived after reduction of CDH and esthetic dissatisfaction of patients with GRs treated with CAF + CM, CAF + EMD, and CAF + CM + EMD.

Xenogenous Collagen Matrix and/or Enamel Matrix Derivative for Treatment of Localized Gingival Recessions: A Randomized Clinical Trial. Part I: Clinical Outcomes.

BACKGROUND: Considering xenogeneic collagen matrix (CM) and enamel matrix derivative (EMD) characteristics, it is suggested that their combination could promote superior clinical outcomes in root coverage procedures. Thus, the aim of this parallel, double-masked, dual-center, randomized clinical trial is to evaluate clinical outcomes after treatment of localized gingival recession (GR) by a coronally advanced flap (CAF) combined with CM and/or EMD. METHODS: Sixty-eight patients presenting one Miller Class I or II GRs were randomly assigned to receive either CAF (n = 17); CAF + CM (n = 17); CAF + EMD (n = 17), or CAF + CM + EMD (n = 17). Recession height, probing depth, clinical attachment level, and keratinized tissue width and thickness were measured at baseline and 90 days and 6 months after surgery. RESULTS: The obtained root coverage was 68.04% ± 24.11% for CAF; 87.20% ± 15.01% for CAF + CM; 88.77% ± 20.66% for CAF + EMD; and 91.59% ± 11.08% for CAF + CM + EMD after 6 months. Groups that received biomaterials showed greater values (P <0.05). Complete root coverage (CRC) for CAF + EMD was 70.59%, significantly superior to CAF alone (23.53%); CAF + CM (52.94%), and CAF + CM + EMD (51.47%) (P <0.05). Keratinized tissue thickness gain was significant only in CM-treated groups (P <0.05). CONCLUSIONS: The three approaches are superior to CAF alone for root coverage. EMD provides highest levels of CRC; however, the addition of CM increases gingival thickness. The combination approach does not seem justified.

Dental Environment Stress: Findings among Lusophone Dental Students

Objective: To perform cross-cultural adaptation of the Dental Environment Stress (DES), to test its construct validity and reliability, and to identify the sources of stress among Brazilian dental students. Material and Methods: The DES was transculturally adapted to Portuguese using translation/back-translation, review by an expert bilingual committee and consensus building. The first version was tested in a sample of 42 dental students to check the understanding level of the alternatives. The final version was applied to all the students enrolled in a Brazilian Public Dental School. Construct validity was assessed through factor analysis, performed by principal components analysis and Varimax rotation and reliability by internal Cronbach's alpha coefficient (95% CI). Wilcoxon rank sum was conducted to test for gender and Kruskall-Wallis for year comparison. Multivariate analysis relied on ordinal logistic regression modeling. Results: Factor analysis revealed five factors that possessed eigenvalues greater than 1.5 and together explained 46.88% of the total variance. Internal consistency of each factor was adequate, with Cronbach's alpha ranging from 0.65 to 0.84. 'Examinations and grades' (82.80%) was the highest scored item. Females presented higher rates, as well as second's and fifth's years students. The entering students were generally concerned with factors related to "Academic Performance", whereas clinical year students with "Insecurity Concerning their Professional Future". Conclusion: The Portuguese version of the DES presented good results, thus it could be a valid instrument to assess the factors of perceived stress in Lusophone countries, subsidizing the development of strategies to minimize the stress and optimize school performance.

Levantamento de seio maxilar por acesso crestal e pressão hidrodinâmica com instalação imediata de implantes / Maxillary sinus lifting with crestal access and hydrodinamic pressure for immediate implant placement

A instalação de implantes dentários na região posterior de maxila pode ser dificultada pela diminuição da quantidade óssea e pelo aumento do seio maxilar. Este artigo relata um caso clínico de instalação de implantes nessa região, com extensa reabsorção óssea e pneumatização do seio maxilar. O paciente foi submetido a um procedimento de elevação da membrana do seio utilizando um sistema de pressão hidrodinâmico, seguido pelo preenchimento com osso xenógeno liofilizado e instalação imediata de implantes. Após um período de seis meses de cicatrização, verificou-se que esse sistema permitiu, de maneira segura e atraumática, a instalação de implantes dentários, preservando o espaço sinusal.

The placement of dental implants in the posterior maxilla may be impaired by the reduced bone quantity and increased maxillary sinus volume. This article reports a case of implant placement with large bone resorption and pneumatization of the maxillary sinus. The patient was submitted to a sinus lifting membrane procedure using a hydrodynamic pressure system followed by filling with lyophilized xenogeneic bone and immediate implant placement. After six months of healing, the clinical results demonstrated that this system provides safe and atraumatic dental implant placement while preserving sinus space.

Estresse em odontologia: adaptação transcultural e validação do Dental Environmental Stress para estudantes de odontologia brasileiros / Stress in dentistry: cross-cultural adaptation and validation of the dental environmental stress for brazilian dental students

A formação do cirurgião-dentista necessita do desenvolvimento de competências em diversas áreas do conhecimento. Além do conhecimento técnico-científico, o acadêmico de odontologia deve desenvolver a capacidade de se relacionar com pacientes e com outros profissionais. Essa complexa formação promove algum grau de estresse durante a faculdade. Para verificação desse estresse e de suas características, o instrumento americano Dental Environmental Stress (DES) foi desenvolvido em 1980. No entanto, para que estudos semelhantes sejam realizados no Brasil, esse instrumento deve passar por um rigoroso processo de adaptação. O objetivo deste estudo é traduzir, realizar a adaptação transcultural, e verificar as propriedades psicométricas do instrumento DES para, posteriormente, avaliar os fatores de estresse presentes em estudantes de odontologia no Brasil. O instrumento foi traduzido e adaptado culturalmente para a população brasileira, de acordo com uma metodologia padronizada. A versão traduzida foi revisada por uma comissão e, em seguida, aplicada em um grupo de 42 estudantes de odontologia para verificar o nível de compreensão das alternativas. Alguns itens tiveram problemas de interpretação e necessitaram ser reelaborados. A versão final foi, então, aplicada a uma amostra de 225 estudantes de Odontologia para verificação das propriedades do questionário. O coeficiente alfa de Cronbach foi utilizado para verificar a consistência interna e para testar a validade de constructo utilizou-se a análise fatorial exploratória. Alguns itens do instrumento original foram considerados como não relevantes e foram retirados do questionário. Pela análise fatorial, encontraram-se cinco fatores, e consistência interna de cada fator foi adequada, com alfa de Cronbach de 0,65 até 0,84. Para verificação dos fatores mais prevalentes, análise univariada e multivariada foram realizadas, considerando o ano de estudo e gênero como possíveis preditores. Os fatores considerados de maior...

Sublingual traumatic ulcerative lesions caused by the eruption of first primary mandibular molars: a case report / Lesión ulcerativa traumática sublingual causada por la erupción del primer molar temporal: reporte de un caso

Traumatic ulceration of the ventral surface of the tongue is an uncommon condition in infants and toddlers, which is often associated with natal and neonatal teeth in newborns. The aim of this report is to present a case of bilateral ulcerative ulcers on the ventral surface of the tongue caused by the eruption of first primary mandibular molars in a 14-month-old male child. The child was able to point to the lesions and also refused to consume certain beverages and foods, which favored an early diagnosis. Clinical treatment consisted of manual smoothing of the sharp edges of both mandibular first molars and a home regimen of lidocaine hydrochloride solution (Xylocaine®, Astra) and a steroid solution of triamcinolone acetonide (Omcilon ­ A, Brystol-Myers) for symptoms relief and lesion healing, respectively. Complete healing of both lesions and normal feeding were both observed at a one-week follow-up exam. Early detection of the lesions and parental compliance with recommended home regimens were key factors for a successful treatment outcome, since untreated cases of tongue ulcerative lesions may evoke feeding difficulties and failure to thrive. Although there are several reports of ulcerative lesions on the tongue caused by dental eruption, they are usually associated with the eruption of mandibular primary incisors (Riga-Fede disease). However, there are no reports of ulcerative lesions caused by other primary teeth.

La ulceración traumática de la superficie ventral de la lengua es una condición poco común en bebés y niños pequeños, la cual se asocia a menudo con los dientes natales y neonatales en los recién nacidos. El objetivo de este reporte es presentar un caso de úlceras bilaterales en la superficie ventral de la lengua causada por la erupción de los primeros molares mandibulares temporales en un infante de sexo masculino de 14 meses de edad. En niño fue capaz de señalar las lesiones y se negó a consumir ciertas bebidas y alimentos, lo que favoreció un diagnóstico precoz. El tratamiento clínico consistió en el suavizado manual de los bordes afilados de los primeros molares inferiores y un régimen casero de solución de clorhidrato de lidocaína (Xilocaína®, Astra) junto a la solución esteroidal de acetónido de triamcinolona (Omcilon - A, Brystol-Myers) para el alivio de los síntomas y curación de la lesión respectivamente. La curación completa de ambas lesiones y la alimentación normal se observó en una semana del control de seguimiento. La detección temprana de las lesiones y el cumplimiento de los padres con los regímenes caseros recomendados, son factores claves para un resultado exitoso del tratamiento, ya que los casos no tratados de estas lesiones ulcerosas pueden provocar dificultades en la alimentación y una evolución inadecuada. Aunque existen varios informes de lesiones ulcerosas en la lengua causada por la erupción dental, que se asocian generalmente con la erupción de los incisivos mandibulares temporales (enfermedad de Riga-Fede). Sin embargo, no existen informes de lesiones ulcerosas causadas por otros dientes temporales.

Geração Y: a motivação para construção do conhecimento / Generation Y: motivation for the construction of knowledge

A construção do conhecimento em saúde ocorre quando o indivíduo toma consciência da aplicação prática do conceito. Práticas de ensino unidirecionais muitas vezes não permitem isso, não motivando a busca de informações que possibilitarão a resolução de problemas. O estudante, atualmente, possui um perfil diferenciado, são jovens pertencentes à geração Y, que cresceram em uma sociedade em transformação pela tecnologia e, agora se encontram nas universidades. Esses jovens não respondem significativamente aos modelos educativos tradicionais, sendo necessárias estratégias de ensino diferenciadas, que buscam a motivação para o desenvolvimento do aprendizado, com uma prática mais participativa e dinâmica. Nesse sentido, o Pró-saúde, concebido para dar suporte à reorientação da formação profissional em saúde, permite abordagens coerentes com essa geração, estabelecendo ações que estimulam a assimilação de conhecimentos críticos no processo de formação profissional. Frente a esses conceitos, elaborou-se um questionário temático sobre a Gripe A, epidêmica em 2009, para motivação no aprendizado de fatores etiológicos e práticas necessárias para a proteção e enfrentamento individual e da sociedade, em uma situação emergencial na saúde. Logo após a aplicação dos questionários foram entregues gabaritos comentados visando o imediato esclarecimento. Observouse então, o interesse dos estudantes em relacionar as suas dúvidas e dificuldades com as respostas corretas, realizando a proposta de motivação no ensino. Dessa forma, verificou-se que essa estratégia, baseada em um instrumento de autoavaliação, permitiu ao aluno progredir em seus conhecimentos baseando-se em seus erros (AU).

The construction of knowledge concerning health occurs when the individual becomes aware of the practical application of a concept. Unidirectional teaching practices often do not allow this, because they do not motivate the search for the information that will allow the resolution of problems. Students today now have a different profile. They are young adults who belong to Generation Y, and grew up in a society being transformed by technology, and now find themselves in college. These young people do not respond significantly to traditional educational models, and require a different teaching strategy that seeks motivation to develop learning, with a more participatory and dynamic form of practice. In this sense, the "Pro-Saúde" (Pro-Health) project was conceived to lend support to redirecting professional health training, and allows different approaches consistent with this generation, establishing actions that encourage the assimilation of critical knowledge for the process of professional training. In view of these concepts, a focused questionnaire was drawn up on Influenza A ­ epidemic in 2009 ­ to aid motivation in learning the etiological factors and practices necessary to protect individuals and society and help them cope in a health emergency situation. Right after applying the questionnaires, templates with comments were handed out to provide an on-the-spot explanation. It was observed that the students showed interest in relating their doubts and difficulties with the correct answers, thus driving the teaching motivation. Accordingly, it was found that this strategy, based on a self-evaluation tool, allowed students to progress in their knowledge, based on their mistakes (AU).

Odontologia no PET-Saúde: pesquisa e integração ensino, serviço e comunidade / Dentistry in the "PET-Saúde" Project: research and integration of teaching, service and community

O objetivo deste trabalho é mostrar ações acadêmicas assertivas fora do âmbito da academia no curso de Odontologia da Universidade Estadual de Londrina (UEL) com a participação dos acadêmicos da área da saúde no Programa de Educação pelo Trabalho para a Saúde (Pet-saúde). Em 2010, o programa Pet-Saúde UEL aconteceu em três etapas: a territorialização da área de atuação, o estudo do referencial teórico sobre a prática do aleitamento materno e a participação dos estudantes na coleta de dados nacional sobre práticas alimentares no primeiro ano de vida. Em seguida, ocorreu a avaliação do programa e a divulgação dos trabalhos realizados em eventos científicos. Em relação ao inquérito realizado, verificou-se que: os índices de aleitamento materno exclusivo e aleitamento materno predominante estão próximos de 50%; o consumo de alimentos com açúcar é elevado para a faixa etária estudada e que o uso da chupeta e da mamadeira interfere no processo da amamentação em crianças menores de seis meses de idade, favorecendo o desmame precoce (p = 0,00). Além disso, concluiu-se que a participação dos estudantes do curso de odontologia da UEL no Projeto Pet-saúde tem favorecido transformações nos processos de geração de conhecimentos, contribuído para a prestação de serviços à população e possibilitado maior integração entre ensino-serviço e a comunidade (AU).

The aim of this study was to show the assertive academic actions performed outside the academic scope of the dentistry course at the State University of Londrina (UEL), with the participation of health field students enrolled in the Tutorial Education Program (PET) promoted by the Health and Education Ministry. In 2010, the "PET-Saúde UEL" program was conducted in three stages: marking off the work area, theoretical reference study on the breastfeeding practice, and participation of students in gathering national data on eating habits in the first year of life. Next, the program was evaluated and the studies presented in scientific events were disseminated. Regarding the survey, it was found that: the rates of exclusive and predominant breastfeeding are close to 50%, that the consumption of sugar-based foods is high for the age group studied, and that the use of pacifiers and bottles interferes with the process of breastfeeding in children under six months of age and favors early weaning (p =0.00). Furthermore, it was concluded that the participation of dentistry students in the "PET-Saúde UEL" project has promoted changes in the processes of broadening knowledge, contributing to public services and enabling greater integration between teaching, health service and community (AU).
