ABSTRACT

ABSTRACT Objective: To identify the salivary metabolites profile of Mucopolysaccharidosis (MPS) types I, II, IV, and VI patients. Material and Methods: The participants were asked to refrain from eating and drinking for one hour before sampling, performed between 7:30 and 9:00 a.m. Samples were centrifuged at 10.000 × g for 60 min at 4°C, and the supernatants (500µl) were stored at −80°C until NMR analysis. The salivary proton nuclear magnetic resonance (1H-NMR) spectra were acquired in a 500 MHz spectrometer, and TOCSY experiments were used to confirm and assign metabolites. Data were analyzed descriptively. Results: Differences in salivary metabolites were found among MPS types and the control, such as lactate, propionate, alanine, and N-acetyl sugar. Understanding these metabolite changes may contribute to precision medicine and early detection of mucopolysaccharidosis and its monitoring. Conclusion: The composition of low molecular weight salivary metabolites of mucopolysaccharidosis subjects may present specific features compared to healthy controls.

ABSTRACT

ABSTRACT Objective: To analyze the relationship between malocclusion and bullying and its impact on the well-being and quality of life of students from low social development areas. Material and Methods: This cross-sectional study included 243 schoolchildren between 10 and 17 years. Malocclusion was analyzed using Dental Aesthetic Index. Bullying and self-perception of the impact of one's oral condition on quality of life and interpersonal relationships were assessed by questions from National Survey of Schoolchildren's Health and Child Perceptions Questionnaire 11-14 (CPQ11-14). Data were analyzed using the Spearman correlation coefficient and Mann-Whitney tests, considering groups: 10-11, 12-14 and 15-17 years. Results: No correlation was observed between malocclusion and bullying. However, in the 12-14 group, poor correlations were found between malocclusion and the CPQ11-14 (0.226) and between malocclusion and being shy/embarrassed due to oral aspects (0.298). Positive correlations were observed between bullying and the impact on the quality of life in the 10-11 (0.420) and 12-14 (0.425) groups. In the older group, a positive correlation (0.724) was observed between the concern about what others think of their oral health and the impact on their quality of life. Conclusion: There was no evidence of a relationship between malocclusion and bullying. However, the oral conditions negatively affected the interpersonal relationships and the student's quality of life.

ABSTRACT

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.

ABSTRACT

Introduction: Minimally invasive dentistry aims to preserve the tooth structure and to achieve this, improved dental materials can be used. Among these, Icon®was developed for infiltration of non-cavitated enamel carious lesions or those located in the external third of dentin. Objective: To report two clinical cases in which Icon® was used to treat interproximal caries lesions in primary and permanent teeth. Case report: Two patients (10 and 13 years) attended the Pediatric Dental Clinic and the clinical and radiographic examination revealed non-cavitated enamel carious lesions and outer third of dentin on teeth 54 distal (D) and 55 mesial (M) (Patient 1), and teeth 24D and 25M (Patient 2), respectively. To restore the lesions, a resin infiltrant (Icon®) was used under rubber dam isolationand according to the manufacturer's recommendations. Results: The patients were assessed immediately after restoration, when complete sealing of the lesion was observed. Patient 1 returned for clinical and radiographic evaluation after 3 months and patient 2 returned after one month, where arrest of the carious lesions was detected. Conclusion: It is concluded that Icon® can be a good option of minimally invasive restorative material, with good applicability in Pediatric Dentistry.


Introdução: A odontologia minimamente invasiva visa maior preservação da estrutura dentária e novos materiais odontológicos vêm sendo utilizados para este fim. Dentre esses, o Icon® foi desenvolvido para infiltração de lesões de cárie não cavitadas localizadas em esmalte e/ou no terço externo de dentina. Objetivo: Relatar dois casos clínicos em que se utilizou o Icon® para tratamento de lesões de cárie interproximais em dentes decíduos e permanentes. Relato do caso: Dois pacientes (10 e 13 anos) compareceram à clínica de Odontopediatriada FO-UFRJ e ao exame clínico e radiográfico foram diagnosticadas lesões cariosas não cavitadas no terço externo de dentina e no esmalte dentário, nos dentes 54 distal (D) e 55 mesial (M) (Paciente 1) e dentes 24D e 25M (Paciente 2), respectivamente. Para restauração das lesões, foi utilizado o infiltrante de resina Icon® sob isolamento absoluto e de acordo com as recomendações do fabricante.

ABSTRACT

Introduction: "Molar-incisor malformation" (MIM) or "Molar root-incisor malformation" is a recently reported dental anomaly of unknown etiology, possibly associated with systemic complications, which affects the development of first permanent molar roots and dental enamel of central incisors. Objective: To conduct a literature review on "Molarincisor malformation", also known as "Molar root-incisor malformation", discussing its clinical, radiographic/tomographic and microscopic aspects; differential diagnosis and treatment possibilities. Sources of data: Electronic search was performed on the MEDLINE database in March 2021, without limit regarding the year of publication. The terms used were "molar-incisor malformation", "molar-root incisor malformation", "root malformation", "root development", "tooth roots", "abnormalities". Synthesis of data: Fifteen articles, most of them case series, were included. In general, medical historyrevealed clinical complications during pregnancy and / or the first years of life. Clinical features included tooth enamel defects in the cervical region of incisors and marked mobility of permanent molars and incisors. Radiographically, partially obliterated pulp chambers, short, thin and incomplete roots of first permanent molars and incisors, were observed. Microscopically, the occurrence of a hypercalcified dentin layer, in the form of a lens, inside the pulp chamber, at the level of the cementum-enamel junction, called"mineralized cervical diaphragm", was reported. Conclusion: "Molar-incisor malformation" is an anomaly characterized by changes in root development, pulp chamber and enamel in permanent molars and incisors. The differential diagnosis includes Dentin Dysplasia type I and Regional Odontodysplasia. Medical and familyhistories are essential for the final diagnosis, and treatment, which despite not having an established protocol, requires a multidisciplinary approach and conventional treatments such as tooth extraction, endodontics, orthodontics, and dental implants.


Introdução: "Malformação molar-incisivo" (MIM) ou "Malformação radicular molarincisivo" é uma anomalia dental recém-reportada de etiologia desconhecida, possivelmente associada a complicações sistêmicas, que afeta o desenvolvimento de raízes dos primeiros molares permanentes e esmalte dentário de incisivos centrais. Objetivo: Realizar uma revisão da literatura sobre "Malformação molar incisivo", também conhecida como "Malformação raiz-molar incisivo", discutindo seus aspectos clínicos, radiográficos/tomográficos, diagnóstico diferencial e possibilidades de tratamento. Fonte dos dados: Busca eletrônica foi realizada na base MEDLINE, em março de 2021, sem limite quanto ao ano de publicação. Os termos pesquisados foram "molarincisor malformation", "molar-root incisor malformation", "root malformation", "root development", "tooth roots", "abnormalities". Síntese dos dados: Quinze artigos, na maioria série de casos, foram incluídos. Em geral, a história médica revelou complicações clínicas durante a gestação e/ou primeiros anos de vida. As características clínicas incluíram defeitos de esmalte dentário na região cervical de incisivos e mobilidadeacentuada de molares e incisivos permanentes. Radiograficamente, observou-se a presença de câmaras pulpares parcialmente obliteradas, raízes de molares e incisivos permanentes curtas, finas e incompletas. Microscopicamente, reportou-se a ocorrência de camada de dentina hipercalcificada, em forma de lente, no interior da câmara pulpar, ao nível da junção cemento-esmalte, denominada de "diafragma cervical mineralizado". Conclusão: A "Malformação molar-incisivo" é uma anomalia caracterizada por alterações do desenvolvimento radicular, da câmara pulpar e do esmalte em molares e incisivos permanentes. O diagnóstico diferencial inclui Displasia dentinária tipo I e Odontodisplasia regional. Históricos médico e familiar são essenciais para o diagnóstico final, e o tratamento, o qual apesar de não ter protocolo estabelecido requer abordagem multidisciplinar e tratamentos convencionais como exodontia, endodontia, ortodontia e implantes dentários.

ABSTRACT

Objective: To evaluate the antimicrobial activity of antibiotic pastes used in lesion sterilization and tissue repair (LSTR) technique, through a novel membrane direct contact methodology against a multispecies biofilm and to establish appropriate dilutions for this method. Methods: CTZ (chloramphenicol, tetracycline, zinc oxide) and two formulations of 3Mix pastes (ciprofloxacin, metronidazole, and minocycline), 3Mix1 and 3Mix3, were evaluated with negative (0.9% saline) and positive (chlorhexidine 0.2%) control groups. Candida albicans and Enterococcus faecalis (24-hour) biofilms (n=10) grown on cellulose membranes were directly exposed to standardized amounts of fresh pastes and control solutions (n=2) for 24h. Membranes were immersed in 900 µl of saline solution, and seven serial dilutions were made for each sample. Plating for each dilution (n=2) was performed on culture media for microbial colony-forming unit (CFU) counting of total microorganisms, Candida spp. and Enterococcus spp. Aiming the comparison between groups, CFU quantification data were transformed into log10 CFU / mL and the Mann-Whitney test was applied (p<0.05). Results: Inhibition of CFU was observed for all pastes, with greatest effects for CTZ paste in medium selective for Candida spp. (p<0.001) and 3Mix1 in non-selective (p<0.000) and selective for Enterococcus spp. (p<0.004). Conclusion: The pastes showed antimicrobial activity against the tested multispecies biofilm, and the proposed direct contact methodology was efficient. Moreover, the dilutions used proved to be appropriate for this methodology.


Objetivo: Avaliar a atividade antimicrobiana de pastas antibióticas utilizadas na técnica Lesion Sterilization and Tissue Repair (LSTR), através de nova metodologia de contato direto com membrana contra um biofilme multiespécies e estabelecer diluições adequadas para avaliação. Métodos: CTZ (cloranfenicol, tetraciclina,óxido de zinco) e duas formulações de pastas 3Mix (Ciprofloxacina, Metronidazol e Minociclina), 3Mix1 e 3Mix3, foram avaliadas, além dos grupos controle, negativo (solução salina a 0,9%) e positivo (clorexidina 0,2%). Biofilmes de Candida albicans e Enterococcus faecalis cultivados sobre membranas de celulose (n=10) durante24 h foram expostos diretamente em contato com quantidades padronizadas de pastas frescas e controles (n = 2) por 24 h. As membranas foram imersas em 900µL de solução salina e sete diluições seriadas foram obtidas por amostra. O plaqueamento para cada diluição (n = 2) foi realizado em meios de cultura para microrganismos totais e seletivos para Candida spp. e Enterococcus spp. para contagem de unidades formadoras de colônias (UFC). Para comparação entre grupos, os dados da contagem de UFC foram convertidos em log10 UFC / mL e o teste Mann-Whitney foi aplicado (p<0,05). Resultados: Observou-se inibição de UFC para todas as pastas, maior para CTZ no meio seletivo para Candida (p<0,001)e 3Mix1 nos demais meios (p<0,004). Conclusão: Concluiu-se que as pastas apresentaram atividade antimicrobiana contra o biofilme multiespécies testado e que a nova metodologia de contato direto proposta foi eficiente. Além disso, as diluições utilizadas mostraram-se adequadas para essa metodologia.

ABSTRACT

O bruxismo em crianças tem se tornado uma preocupação crescente nos últimos anos. É definido como uma atividade involuntária dos músculos mastigatórios caracterizada por apertar ou ranger os dentes e pode ser de dois tipos, do sono (BS) ou da vigília (BV). A prevalência do BS na população infantil varia de 5,9% a 49,6%.Fatores funcionais, estruturais e psicológicos podem estar envolvidos com a presença do bruxismo. O diagnóstico é feito por meio de questionários, exame clínico e exame de polissonografia, que é o padrão ouro. Por ser uma desordem de origem central e não periférica, o BS não tem cura. Logo, faz-se o controle, que abrange prevenção, abordagem e gerenciamento de consequências. Atualmente, são citadas na literatura inúmeras técnicas de manejo para oBS. Este trabalho tem o objetivo de revisar a literatura atual referente ao controle do BS em crianças e confeccionar uma cartilha informativa direcionada aos pais, expondo os benefícios da higiene do sono como controle basal do BS. Conclui-se que a higiene do sono, apesar de baixa evidência científica, é considerada a primeira linha de abordagem para o bruxismo do sono infantil.


Children bruxism has become a growing worry in the last years. It is defined as an involuntary activity of masticatory muscles characterized by tightening or gritting the teeth and can be of two types, sleep (SB) or wake (WB). The prevalence of SB in infant population varies from 5,9% to 49,6%. Functional, structural and psychological factors may be involved in the presence of bruxism. The diagnosis is made through questionnaires, clinical examination and polysomnography, which is the gold standard. Because it is a central and non-peripheral origin disorder, SB has no cure. Therefore, control is made, which includes prevention, approach and consequence management. Currently, numerous management techniques for SB are cited in the literature. This work aims to review the current literature regarding the control of SB in children and to make an informative booklet directed to parents, exposing the benefits of sleep hygiene as basal control of BS. It is concluded that sleep hygiene, despite low scientific evidence, is considered the first line of approach for children sleep bruxism.

ABSTRACT

Objective: Evaluate the impact of oral health status on the quality of life and personal satisfaction among adolescents from urban and rural areas, in Nova Friburgo, Brazil. Methods: Adolescents between 11 and 14 years, enrolled in the schools participating in the Health in School Program (HSP) of rural and urban of this city (n = 509), received the consent form for the participation in this study, along with the economic questionnaire to be handed to the responsible. Adolescent´s oral health status was evaluated clinically, through the Decayed, Missing and Filled Teeth (DMFT); pulpal involvement, ulceration, fistula and abscess criteria (PUFA); and Dental Treatment Needs Index (DTNI). The quality of life was measured through the Child Perception Questionnaire (CPQ11-14), while personal satisfaction´s evaluation, through the Subjective Happiness Scale (SHS), both as interview. Statistical tests were performed (Chi-Square; Fisher's exact; Mann-Whitney) with level of significance of 5%. Results: The final sample comprised 161 adolescents. The impact of oral health status on the quality of life of adolescents from both areas was not significantly different, although the aggravation of the oral condition showed a tendency to worse the quality of life. Similarly, there was no relation of the oral status with personal satisfaction, without differences between the groups. It was observed that rural adolescents presented better quality of life (p<0.010), while the urban ones had higher degree of personal satisfaction (p<0.001). Conclusion: Oral health status had a negative impact on the quality of life, but had no relation to personal satisfaction, regardless of the demographic area.


Objetivo: Avaliar o impacto do estado de saúde bucal na qualidade de vida e na satisfação pessoal de adolescentes das áreas urbana e rural de Nova Friburgo, Brasil. Métodos: Adolescentes entre 11 e 14 anos, matriculados nas escolas participantes do Programa Saúde na Escola (PSE) da zona rural e urbana desta cidade (n = 509), receberam o Termo de Consentimento Livre e Esclarecido para a participação neste estudo,juntamente ao questionário econômico a ser entregue para o responsável. O estado de saúde bucal do adolescente foi avaliado clinicamente, por meio dos índices Cariados, Perdidos e Obturados (CPOD); critérios de envolvimento pulpar, ulceração, fístula e abscesso (PUFA); e Índice de Necessidades de Tratamento Odontológico (INTO). A qualidade de vida foi mensurada por meio do Child Perception Questionnaire (CPQ11- 14), enquanto a avaliação da satisfação pessoal, por meio da Subjective Happiness Scale (SHS), ambos na forma de entrevista. Foram realizados testes estatísticos (Qui-Quadrado; Exato de Fisher; Mann-Whitney) com nível de significância de 5%. Resultados: A amostra final foi de 161 adolescentes. O impacto do estado de saúde bucal na qualidade de vida dos adolescentes de ambas as áreas não foi significativamente diferente, embora o agravamento da condição bucal tenha apresentado tendência a piorar a qualidade de vida. Da mesma forma, não houve relação da condição oral com a satisfação pessoal, sem diferenças entre os grupos. Observou-se que os adolescentes rurais apresentaram melhor qualidade de vida (p<0,010), enquanto os urbanos apresentaram maior grau de satisfação pessoal (p<0,001). Conclusão: O estado de saúde bucal teve impacto negativo na qualidade de vida, mas não teve relação com a satisfação pessoal, independente da área demográfica.

ABSTRACT

Abstract Objective: To verify the concordance in the evaluation of the apical limit of obturation (ALO) in filled root canals of primary teeth between digital and visual methods. Material and Methods: Twenty periapical radiographs of endodontically treated primary teeth were digitalized and evaluated by an endodontics specialist (E1), a PhD pediatric dentist (E2), and a MSc general dentist (E3). Calibrated evaluators (Kappa = 1.00) analysed the images in a light-isolated environment two times (D1 and D2) with a one-week interval between evaluations. ALO scores were categorized as overfilled, flush-filled and underfilled. Results: The intra-rater reliability between methods was 0.82 (D1) and 0.75 (D2) for E1, 0.93 (D1 and D2) for E2, and 0.94 (D1 and D2) for E3. Inter-rater reliability ranged from 0.71 (E1 × E3) and 1.00 (E1 × E2) for the visual method to 0.76 (E1 × E3) and 0.88 (E1 × E2) for the digital method. Spearman correlation coefficients showed a similar ranking among the evaluators. There was greater disagreement among the underfilled and ideal scores. For all evaluators, the digital method favoured the identification of the ideal score. Conclusion: Both methods are suitable for the determination of the ALO of filled primary teeth and can be used in clinical practice.

Objective:This study aimed to report a clinical case in which the surgical technique ofulectomy was used in conjunction with orthodontic treatment to aid the eruptionof a maxillary central incisor. Case Report: Male patient, 13 years old, Angle ClassI in the mixed dentition stage, with the tooth 21 impacted and reduced space forits eruption due to the migration of adjacent teeth. Fixed appliance was mountedwith Edgewise brackets using 0.20" stainless steel archwire with tight omega andactive spring between teeth 11 and 22 to recover the space of 21, but the passiveeruption was not observed. A fibrous gingival tissue was found, which by palpationrevealed the incisal edge of the tooth 21. The patient was referred to a pediatricdental clinic for a ulectomy. The minimally invasive surgical procedure consistedof the excision of the gingival tissue that covered the crown of the tooth 21 allowingits eruption in the dental arch. After the surgery, the teeth erupted and correctiveorthodontic treatment continued. Conclusion: The ulectomy technique associatedwith orthodontic treatment allowed to reestablish conditions for the developmentof dentition with satisfactory aesthetic and functional characteristics.

ABSTRACT

Abstract This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused by dental caries or trauma, in 23 children (2-7 years old). A single trained operator performed the CT in a single visit in cases without periapical or interradicular radiolucency (PIR) or in multiple visits in cases with PIR. Participants were selected based on specific inclusion and exclusion criteria, and randomly allocated into two groups: Group 1 (G1) - iodoform paste (iodoform + camphorated parachlorophenol + ointment comprising prednisolone acetate 5.0 mg and rifamycin 1.5 mg); Group 2 (G2) - Calen®/ZO paste. Treated teeth were restored with composite resin immediately after the root canal filling. The outcomes were evaluated clinically and radiographically according to specific criteria. Two blinded and standardized evaluators assessed the radiographic outcomes. We used descriptive analyses due to the small sample size. CTs were performed due to caries lesions in 70.4% of the cases and due to trauma in 29.6%. Only one tooth of G1 was unsuccessful; hence, pulpectomy performance in both groups was not influenced by the filling material, nor by any other analyzed variable. The level of the root canal filling was better in the Calen®/ZO group. The clinical and radiographic twelve-month outcomes indicated successful treatment, independently of the root filling material used.

ABSTRACT

Introduction: There is no consensus on the literature about the best root canal filling material for primary teeth. Objective: The aim of this study was to describe the root canal filling materials most widely used in clinical pediatric dentistry, showing the observed success rates. Sources of data: A search, limited to the last 10 years and, no language restriction, was performed in October 2018 in the PubMed, Cochrane and LILACS databases using the terms "pulpectomy" and "primary teeth". This narrative literature review included clinical and randomized controlled trials conducted on children who had undergone pulpectomy as root canal therapy, with at least six months of clinical and radiographic follow-up. Synthesis of data: A total of 254 papers were retrieved from the databases. After applying the inclusion and exclusion criteria, 25 papers were included in this review. Zinc oxide and eugenol (ZOE) based paste was still the most widely used root canal filling material for primary teeth in pediatric clinical research, showing an overall clinical and radiographic success ranging from 63.3% to 93.3%. Conclusion: ZOE based paste is still the most used material for root canal filling in primary teeth, although there is a trend in the use of iodoform with calcium hydroxide pastes, which show high frequencies of success.

ABSTRACT

Introduction: Minimally invasive dental procedures are aimed at recovering function and aesthetics in a practical manner, providing excellent treatment options. Bulk-fill composites offer some benefits, such as placement in single increments up to 4-mm thickness, decreased polymerization shrinkage, and general reduction in clinical time, while keeping aesthetic properties similar to those of conventional composite resins. Objective: To report two clinical cases of class I restorations in permanent molars with dentin carious lesions (ICDAS 4) treated with bulk-fill composites using the occlusal stamp technique. Cases were followed up for 6 months and the restorations were evaluated according to the World Dental Federation (FDI) and Public Health Service (USPHS) criteria. Case report: Restorations were performed using the following materials: Case 1 ­ Filtek ™ bulk-fill flowable resin (3M ESPE) associated with Filtek Z350 XT resin (3M ESPE); Case 2 - Filtek bulk- ill packable resin (3M ESPE). Three blinded evaluators assessed the materials and techniques in the follow-up period. Results: Case 1 achieved the lowest scores by the FDI and USPHS criteria, presenting better aesthetic, functional, and biological properties. Conclusion: Both treatments were clinically satisfactory after 6 months. Bulk-fill composites are good materials, allowing for a fast, effective, and quality treatment for the pediatric patient.

ABSTRACT

Article This study evaluated comparatively two configurations (powder and putty) of a composite biomaterial based on PLGA (Poly(lactide-co-glycolide)/nanoescale hydroxyapatite (ReOss®, Intra-Lock International) through microscopic morphology, in vitro cytotoxicity, biocompatibility and in vivo response as a bone substitute. SEM and EDS characterized the biomaterials before/after grafting. Cytocompatibility was assessed with murine pre-osteoblasts. Osteoconductivity and biocompatibility were evaluated in White New Zealand rabbits. Both configurations were implanted in the calvaria of eighteen animals in non-critical size defects, with blood clot as the control group. After 30, 60 and 90 days, the animals were euthanized and the fragments containing the biomaterials and controls were harvested. Bone blocks were embedded in paraffin (n=15) aiming at histological and histomorphometric analysis, and in resin (n=3) aiming at SEM and EDS. Before implantation, the putty configuration showed both a porous and a fibrous morphological phase. Powder revealed porous particles with variable granulometry. EDS showed calcium, carbon, and oxygen in putty configuration, while powder also showed phosphorus. After implantation EDS revealed calcium, carbon, and oxygen in both configurations. The materials were considered cytotoxic by the XTT test. Histological analysis showed new bone formation and no inflammatory reaction at implant sites. However, the histomorphometric analysis indicated that the amount of newly formed bone was not statistically different between experimental groups. Although both materials presented in vitro cytotoxicity, they were biocompatible and osteoconductive. The configuration of ReOss® affected morphological characteristics and the in vitro cytocompatibility but did not impact on the in vivo biological response, as measured by the present model.


Resumo Este estudo avaliou comparativamente duas configurações (pó e massa) de um biomaterial composto com base de PLGA (Poli(láctico-co-glicólico)/hidroxiapatita em nanoescala (ReOss®, Intra-Lock International) através da morfologia microscópica, citotoxicidade in vitro, biocompatibilidade e resposta in vivo como substituto ósseo. MEV e EDS caracterizaram os biomateriais antes/após o enxerto. A citocompatibilidade foi avaliada em pré-osteoblastos murinos. A osteocondutividade e a biocompatibilidade foram avaliadas em coelhos Branco da Nova Zelândia. Ambas as configurações foram implantadas na calvária de dezoito animais em defeitos não-críticos, com coágulo sanguíneo como grupo controle. Após 30, 60 e 90 dias, os animais foram eutanasiados e os fragmentos contendo os biomateriais e controles coletados. Blocos ósseos foram embebidos em parafina (n=15) destinados às análises histológica e histomorfométrica, e em resina (n=3) destinadas à MEV e EDS. Antes da implantação, a configuração massa mostrou ambas fases morfológicas porosa e fibrosa. O pó revelou partículas porosas com granulometria variável. EDS mostrou cálcio, carbono e oxigênio na configuração massa, enquanto o pó mostrou também fósforo. Após a implantação a EDS revelou cálcio, carbono e oxigênio em ambas configurações. Os materiais foram considerados citotóxicos pelo teste XTT. A análise histológica mostrou nova formação óssea e nenhuma reação inflamatória nos sítios de implante. Entretanto, a análise histomorfométrica indicou que a quantidade de osso neoformado não foi estatisticamente diferente entre os grupos experimentais. Embora ambos os materiais tenham apresentado citotoxicidade in vitro, foram biocompatíveis e osteocondutores. A configuração do ReOss® afetou as características morfológicas e a citocompatibilidade in vitro, porém não impactou a resposta biológica in vivo, como medido pelo presente modelo.

ABSTRACT

Abstract Dental caries is an oral pathology associated with both lifestyle and genetic factors. The caries process can be influenced by salivary composition, which includes ions and proteins. Studies have described associations between salivary protein polymorphisms and dental caries experience, while others have shown no association with salivary proteins genetic variability. The aim of this study is to assess the influence of salivary protein polymorphisms on the risk of dental caries by means of a systematic review of the current literature. An electronic search was performed in PubMed, Scopus, and Virtual Health Library. The following search terms were used: “dental caries susceptibility,” “dental caries,” “polymorphism, genetics,” “saliva,” “proteins,” and “peptides.” Related MeSH headings and free terms were included. The inclusion criteria comprised clinical investigations of subjects with and without caries. After application of these eligibility criteria, the selected articles were qualified by assessing their methodological quality. Initially, 338 articles were identified from the electronic databases after exclusion of duplicates. Exclusion criteria eliminated 322 articles, and 16 remained for evaluation. Eleven articles found a consistent association between salivary protein polymorphisms and risk of dental caries, for proteins related to antimicrobial activity (beta defensin 1 and lysozyme-like protein), pH control (carbonic anhydrase VI), and bacterial colonization/adhesion (lactotransferrin, mucin, and proline-rich protein Db). This systematic review demonstrated an association between genetic polymorphisms and risk of dental caries for most of the salivary proteins.

ABSTRACT

Com o avanço das pesquisas em biomateriais, tem sido sugerido que a melhor osteocondutividade da hidroxiapatita seria alcançada se o seu cristal estivesse mais próximo da estrutura, tamanho e morfologia da apatita biológica, por isso a nano-hidroxiapatita (nano-HA) é de grande interesse atual. Os íons estrôncio são conhecidos por reduzir a reabsorção óssea, induzir a atividade osteoblástica e estimular a formação óssea. O objetivo deste estudo foi avaliar a biocompatibilidade e a osteocondução em defeitos cirúrgicos preenchidos com microesferas de nano-hidroxiapatita contendo estrôncio a 1% (nano-SrHA), microesferas de nano-HA estequiométrica (nano-HA) em comparação ao coágulo (controle). Quatro ovelhas Santa Inês, pesando em média 32 kg, foram anestesiadas e submetidas a três perfurações de 2 mm de diâmetro na face medial da tíbia. Os defeitos cirúrgicos foram preenchidos com coágulo sanguíneo, microesferas de Sr-HA 1% e microesferas de HA. Após 30 dias as amostras foram trefinadas (6 mm), descalcificadas, processadas para inclusão em parafina e coradas com hematoxilina e eosina (HE) para avaliação histológica com microscopia de luz. Todos os grupos revelaram neoformação óssea da periferia para o centro do defeito, sendo o grupo nano-SrHA com menor intensidade dentre os estudados. Presença de discreto infiltrado inflamatório mononuclear em todos os grupos experimentais. Células gigantes do tipo corpo estranho só foram observadas no grupo da HA. Áreas de neoformação óssea foram observadas em íntimo contato com ambos os biomateriais. De acordo com os resultados obtidos, microesferas de HA e SrHA 1% são biocompatíveis e apresentam propriedade de osteocondução.


With the advances on biomaterials research have suggested that the best osteoconductivity of hydroxyapatite could be achieved if the crystal was closer to the structure, size and morphology of biological apatite, so the nano-hydroxyapatite (nano-HA) is of current interest. Strontium ions are known to reduce bone resorption, induce osteoblastic activity and thus stimulate bone formation. The aim of this study was to evaluate the biocompatibility and osteoconductive in surgical defects filled with spheres of nano-hydroxyapatite containing strontium 1% (nano-SrHA), nano-hydroxyapatite stoichiometric (nano-HA) when compared to the blood clot (control). Four Santa Inês sheeps, weighing on average 32 kg were anesthetized and subjected to three perforation 2 mm in diameter on the medial site of tibia. The surgical defects were filled with blood clot, Sr-HA 1% microspheres and HA microspheres. After 30 days the samples were trephyned (6 mm), decalcifi ed, processed for embedding in paraffi n and stained with hematoxilin and eosin (HE) for histological evaluation with light microscopy. All groups showed new bone formation from the periphery to the center of the defects, and the group nano-Sr with a lesser extent among those studied. The mononuclear inflammatory infiltrate remained mild in all experimental groups. The presence of giant cells type foreign body was detected only in the HA group. Areas of bone formation were detected in close contact with biomaterials. According to the results spheres containing nano-SrHA 1% and nano-HA can be considered as biocompatible and with osteoconductive properties.
