ABSTRACT

Abstract Objectives This is a double-blind, split-mouth, randomized clinical study that aims to evaluate the influence of bulk-fill composite packaging presented in syringes (BSy) and capsules (BCa), and the effect of selective enamel etching (SEE) on the clinical performance of class I and II bulk-fill resin composite restorations after 24 months. Methodology A total of 295 class I or class II restorations were performed on 70 patients. One universal adhesive was applied in all restorations. SEE was used in 148 restorations and self-etching mode (SET) in 147 restorations. After the adhesive application, cavities were restored with Filtek Bulk-fill Posterior Restorative in syringes (BSy), Filtek One Bulk-fill in capsules (BCa), or Filtek Supreme Ultra in syringes with the incremental technique (In). All restorations were evaluated using the FDI criteria after one week and after six, 12, and 24 months. Kaplan-Meier survival analysis and Pearson's Chi-square test were used (α=0.05) for statistical analysis. Results After 24 months, 62 patients were evaluated and four restorations were lost due to fracture (one for SEEBSy, two for SEEIn, and one for SETIn). No significant differences in the fracture and retention rate were found between groups (p>0.05). SEE showed significantly fewer marginal adaptation defects than SET (p<0.05). BCa and BSy groups showed fewer marginal discrepancies compared to In (p<0.05). Restorations performed with BCa showed less color mismatch than BSy or In (p<0.05). Conclusion Although all restorations exhibited satisfactory clinical performance after 24 months of clinical service, the clinical behavior of class I and II restorations' improved when performed with a bulk-fill composite in capsules, mainly when associated with a universal adhesive applied with SEE.

ABSTRACT

ABSTRACT Objective: To compare clinical and radiographical pulpectomy outcomes in primary teeth filled with different pastes. Material and Methods: The sample included thirty-eight teeth indicated for pulpectomy due to irreversible pulp inflammation or necrosis from thirty patients (2 to 9 years old). The first appointment comprised chemomechanical preparation (2.5% sodium hypochlorite), smear layer removal (6% citric acid), intracanal dressing and temporary restoration. Seven days later, teeth were randomly assigned to filling with iodoform (IP) or calcium hydroxide with zinc oxide (CHZO) based pastes and temporarily restored. Final restoration (composite resin) occurred at the 3rd appointment. Data from baseline, 6 and 12 months were analysed using descriptive and inferential statistics (p≤0.05). Results: The overall frequency of success was 63.6% (n=21), with no significant difference between groups (IP=62.5% n=10; CHZO=64.7% n=11, p=0.59). Multiradicular teeth, overfilled canals and teeth whose coronal restoration have been lost were significantly associated with failure (p=0.01, p=0.04 and p<0.001, respectively). Conclusion: After 12 months, both pastes showed similar outcomes and can be used as good options for pulpectomies in primary teeth. Moreover, tooth location, extent of the root canal filling, and integrity of final restoration during the follow-up influenced the outcome of pulpectomies.

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: Studies of twins are important because environmental and genetic factors seem to be related to the phenotypic alterations. Objective: This paper presents a unique case of monozygotic twins with mirror image of a retained primary central incisor. Case report: Twin male brothers, 9-years-old, presented prolonged retention of the primary central upper incisor. The over-retained teeth in one twin were a mirror image of those in the other twin. The first twin presented a prolonged retention of the tooth 51 whereas the other twin presented a prolonged retention of tooth 61. After radiographic exams the over-retained teeth were extracted. Conclusion: Twins may show similarity in pattern of dental anomalies supporting the influence of genetic factors. In identical twins the location of diagnosed anomalies can be mirror imaged. This fact should lead the professional to examine the pair of twins in order to diagnose any dental anomaly that may be present.


Introdução: Estudos feitos em gêmeos são importantes porque fatores ambientais e genéticos parecem estar relacionados às alterações fenotípicas. Objetivo: Este artigo apresenta um caso raro de gêmeos monozigóticos apresentando imagem em espelho de retenção prolongada de incisivos centrais decíduos superiores homólogos. Relato do caso: Os irmãos gêmeos, com 9 anos de idade, não apresentavam história de trauma orofacial ou doença comum da infância. Após exames clínicos e radiográficos foram identificados a retenção do dente 51 no gêmeo 1 e do dente 61 no gêmeo 2. Em ambos os pacientes, os dentes 11 e o 21 estavam em erupção. O tratamento proposto foi a exodontia dos dentes decíduos com anestesia local e acompanhamento. Conclusão: Gêmeos podem apresentar semelhança no padrão de anomalias dentárias devido à influência de fatores genéticos. Adicionalmente, em gêmeos monozigóticos, a localização das anomalias diagnosticadas pode se apresentar invertidas ou imagem em espelho. Esse fato deve estimular o profissional a examinar o par de gêmeos para diagnosticar qualquer anomalia dentária que possa estar presente. O diagnóstico precoce e tratamento adequados devem ser realizados para evitar danos funcionais e estéticos em pacientes com retenções dentárias.

ABSTRACT

Abstract The objectives of this double-blind randomized clinical trial were to compare (a) the clinical times and (b) the occurrence and severity of postoperative sensitivity, of posterior restoration that used a universal adhesive, in a self-etch or selective enamel-etching technique, along with incremental or bulk-fill composites (presented in syringes or capsules). A total of 295 posterior restorations were placed according to the following groups: SETB - self-etch/bulk-fill in syringe; SETC - self-etch/bulk-fill in capsules; SETI - self-etch/incremental; SEEB - selective enamel-etching/bulk-fill in syringe; SEEC - selective enamel-etching/bulk-fill in capsules; and SEEI - selective enamel-etching/incremental. Clinical time was assessed by a reason (s/mm3) between the total volume of resin inserted and the total time required to perform the restorations. Postoperative sensitivity was evaluated using two scales (Numeric Rating Scale and Visual Analogue Scale). Mean clinical time results, analyzed by Wald's Chi-square, showed significant statistical differences among all groups (p<0.001), indicating that the restorative strategy affected the time required for the restoration. A generalized estimating equation model statistical analysis, performed to compare postoperative sensitivity, showed that neither the restorative technique, the adhesive strategy nor the presentation mode of the bulk-fill composite affected the overall risk of postoperative sensitivity (4.06 [2.22-6.81]). The use of bulk-fill composite, presented in capsules or syringes, is less time consuming and does not increase the risk or intensity of postoperative sensitivity relative to the traditional incremental technique.

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

A cronologia de irrupção é de fundamental importância em se tratando da busca por uma oclusão balanceada. Contudo, certas patologias podem alterar a cronologia e com isso influenciar o estabelecimento da oclusão. O odontoma é o tipo mais comum de tumor odontogênico, sendo representado por 70% dos casos cuja formação é definida como má-formação benigna. A localização mais frequente é observada na região anterior da maxila, sendo o dente canino o mais envolvido, entretanto exceções tem sido observada. Este trabalho teve por objetivo avaliar a importância da inter-relação de especialidades no diagnóstico e conduta frente à alterações na cronologia de irrupção de dentes permanentes. Realizou-se revisão da literatura sobre a temática, nas bases Medline via PubMed, SciELO e Bireme, até novembro de 2017. Os descritores utilizados foram "pediatric dentistry", "unerupted" e "dental eruption". Pode-se constatar a existência de poucos trabalhos descrevendo a importância da inter-relação entre especialidades, sendo mais divulgados revisões de literatura sobre determinadas patologias, bem como relatos de casos, com as condutas frente a existência de tais patologias. Diante do exposto, acredita-se que quando as especialidades trabalham em conjunto, o desdobramento do caso clínico faz-se de forma adequada, beneficiando o prognóstico, além de melhorar a qualidade de vida do paciente.


The chronology of irruption has fundamental role when it is considered the balanced occlusion. However, some pathologies may alter the chronology and thereby influence the establishment of the occlusion. This study aimed to evaluate the importance of the interrelation of specialties in the diagnosis and management of changes in the chronology of permanent teeth eruption. In the first paper, a review of the literature on the subject was carried out in the Medline databases via PubMed, SciELO and Bireme, until November 2017. The descriptors used were "pediatric dentistry", "unerupted" e "dental eruption". It was possible to verify the existence of few studies describing the importance of the interrelation between specialties, being more published literature reviews on certain pathologies, as well as case reports, with managements used with such pathologies. It could be concluded that when the different specialties work together, the unfolding of the clinical case is done adequately, benefiting the prognosis, besides improving the quality of life of the patient.

ABSTRACT

Aim: To present the report of a female patient, 10 years old, referred for treatment in the Dentistry Clinic of a Brazilian public university. Case report: The patient's oral health condition was unfavorable with biofilm accumulation, pain report and chewing difficulty. After anamnesis, clinical and radiographic examination, the treatment plan included removal of infectious foci (54, 55, 64, 65, 74, 75, 85, 16, 36 and 46) followed by prosthetic rehabilitation. At this stage, the functional restoration of the lower arch was restricted by the imminent eruption of the premolars. In the upper arch, the maintenance of the mesio-distal diameters aims to guarantee the chronological sequence of successors irruption and establishment of normal occlusion. During the monthly follow-up consultations the patient presents a more spontaneous smile, although she still needs constant reinforcement in oral hygiene habits. Conclusions: The rehabilitation of patients with loss of permanent teeth during the mixed dentition phase should consider the peculiarities of this period for the restoration of health without altering the normal pattern of occlusal development.

ABSTRACT

A fluoretação da água, apoiada pela Política Nacional de Saúde Bucal, tem sido um desafio no Brasil, devido a algumas insuficiências atuais na gestão pública para a implantação e controle desta medida. Este estudo objetivou vigiar, de forma periódica e sistemática, os níveis de fluoretos na água para consumo humano, em Nova Friburgo - RJ- Brasil (NF), por um período de 12 meses, como medida de heterocontrole, realizada por uma universidade pública. As amostras de água foram coletadas mensalmente, em duplicata, em 26 localidades em todo o município e em datas estabelecidas por sorteio. O método para medir a concentração de fluoretos nas amostras de água foi o eletrométrico, utilizando-se um potenciômetro digital com eletrodo específico para o íon flúor. A concentração de fluoretos nas amostras foi analisada de acordo com padrões fornecidos pelo Cecol/USP (2011). Os dados mostraram grande variação na concentração de fluoretos nas amostras, variando entre um mínimo de 0,00 ppmF e um máximo de 0,98 ppmF, com algumas dentro do intervalo de 0,65 e 0,94 ppmF, considerado o de melhor benefício para prevenir a cárie dentária. A concentração de fluoretos na água de abastecimento público do município foi considerada abaixo dos níveis mínimos exigidos, na maioria das amostras avaliadas, mesmo naquelas pertencentes às Estações de Tratamento de Água (ETA), cuja medida de fluoretação fora previamente implantada. Desta forma, a fluoretação da água e seu respectivo heterocontrole deveriam ser estabelecidos de forma contínua em NF, já que são medidas públicas relevantes para a promoção de saúde bucal.


Water fluoridation, supported by the Brazilian Oral Health Policy, has been a challenge as a public measure to protect Oral Health, due to some current insufficiencies in public management for the implantation of this measure in most Brazilian cities. The present study aimed to monitor, the levels of fluoride in drinking water in Nova Friburgo - RJ-Brazil (NF), on a regular and a systematic manner for a 12 months period, as an external control measurement performed by a public university. Water samples were collected, in duplicate, from 26 localities throughout the city, on a monthly basis, on randomly established dates. The fluoride concentration in the water samples was measured by using an ion-specific electrode coupled to a potentiometer, according to standards supplied by Cecol/USP (2011). Data showed a large variation of fluoride concentration in water samples, ranging from minimum 0.00 ppmF and maximum 0.98 ppmF, with few samples into the interval between 0.65 and 0.94 ppmF, which had the best benefit to prevent dental caries. Fluoride concentration in public water in this city can be considered under the minimum required levels in most of the evaluated samples, even in those from the Water Treatment System (WTS), which has water fluoridation. Thus, water fluoridation and its external control should be established on a regular basis in Nova Friburgo-RJ, Brazil because they are relevant public measures to promote oral health.

ABSTRACT

AIM: To identify the prevalence of dental caries in inland Brazilian adolescents, and to analyze the influence of socio-demographic and clinical variables, and access to dental service on caries experience. METHODS: This study had a non-probabilistic sample comprising 504 adolescents aged 12 years, attending public schools in the city of Nova Friburgo, mountain region of Rio de Janeiro, Brazil. The World Health Organization (WHO, 1997) criterion was used by previously calibrated examiners to report dental caries. Variables were obtained by means of a semi-structured questionnaire applied to the adolescents' parents. RESULTS: The D3MFT mean was 1.90 and the Significant Caries (SIC) Index was 4.54, mainly represented by the carious component. Multiple logistic regression analysis revealed that parents with over 8 years of schooling (OR=0.579), absence of pain (OR=0.396) and not visiting the dentist (OR=0.270) might suggest protective factors against the disease; the possible risk factors were male gender (OR=1.982) and pain, extraction and others were reasons for consultation (OR=2.435). CONCLUSIONS: Although the prevalence of caries was slightly below the national mean, polarization of the disease was clearly observed. Education and no access to the dentist led to protection against the disease. These results may contribute to planning of oral health actions directed towards this target population for the control of caries...

ABSTRACT

JUSTIFICATIVA E OBJETIVOS: As queixas de sintomas otológicos podem estar associadas a quadros de disfunção temporomandibular (DTM). A placa miorrelaxante é uma alternativa de tratamento para a DTM, pois oferece oclusão ideal para o paciente, atuando nos sintomas de dor. Considerando as características conservadoras e reversíveis da terapia de suporte com placa miorrelaxante, o objetivo deste estudo foi avaliar seu impacto na frequência de alterações otológicas em pacientes com DTM. MÉTODO: Realizou-se estudo de intervenção em 35 pacientes com sintomas otológicos associados à DTM. Foram considerados portadores de DTM aqueles que apresentassem pelo menos três sinais e três sintomas da morbidade, sendo um deles otalgia, zumbido, sensação de hipoacusia, sensação de plenitude auricular ou tontura. Os pacientes foram submetidos a exame clínico, orientações e confecção de placa miorrelaxante maxilar em resina acrílica termoplastificável. Ajustes da placa e avaliação dos sintomas foram realizados quinzenalmente. Utilizou-se o teste Exato de Fisher para análise estatística da diferença entre a prevalência de sinais e sintomas antes (AN) e após (AP) a terapia, com nível de significância de 5% (p < 0,05). RESULTADOS: Dezenove pacientes concluíram o tratamento. Observou-se redução na prevalência de sinais e sintomas otológicos: zumbido (AN = 14; AP = 6; p = 0,009), otalgia (AN = 13; AP = 4; p = 0,003), sensação de plenitude auricular (AN = 12; AP = 4; p = 0,006), tontura (AN = 11; AP = 4; p = 0,009) e de hipoacusia (AN = 10; AP = 2; p = 0,001). CONCLUSÃO: A placa miorrelaxante é uma terapia conservadora e reversível que mostrou ser capaz de melhorar os sintomas otológicos associados à DTM.


BACKGROUND AND OBJECTIVES: Otological symptoms complaints may be associated to temporomandibular joint disorders (TMJD). Occlusal splint is an alternative to treat TMJD because it provides ideal occlusion to patients, acting on painful symptoms. Considering the conservative and reversible characteristics of supportive therapy with occlusal splints, this study aimed at evaluating its impact on the frequency of otological changes in TMJD patients. METHOD: An intervention study was carried out with 35 patients with TMJD-associated otological symptoms. TMJD patients were considered those with at least three signs and three symptoms of morbidity, being one of them earache, tinnitus, sensation of hypoacusis, ear fullness or dizziness. Patients were submitted to clinical evaluation, orientations and fabrication of maxillary occlusal splint in thermoplastic acrylic resin. Splint adjustments and symptoms evaluation were performed fortnightly. Fisher Exact test was used for statistical analysis of the prevalence of signs and symptoms before (BE) and after (AF) therapy with significance level of 5% (p < 0.05). RESULTS: Nineteen patients have finished the treatment. There has been decrease in the prevalence of otological signs and symptoms: tinnitus (BE = 14; AF = 6; p = 0.009), earache (BE = 13; AF = 4; p = 0.003), ear fullness (BE =12; AF = 4; p = 0.006), dizziness (BE = 11; AF = 4; p = 0.009) and hypoacusis (BE = 10; AF = 2; p = 0.001). CONCLUSION: Occlusal splint is a conservative and reversible therapy able to improve TMJD-related otological symptoms.

ABSTRACT

Objetivo: O objetivo deste artigo é relatar o caso clínico de um paciente do gênero masculino, de 29 anos de idade, atendido na Clínica da Dor de uma instituição de ensino superior, diagnosticado como portador de paralisia facial de Bell e desordem temporomandibular, bem como de descrever a conduta terapêutica adotada. Relato de caso: O paciente relatava como queixa principal dor contínua e localizada, no lado direito da face, na região da articulação temporomandibular (ATM), com início há dois anos e piora durante os movimentos de abertura bucal e a mastigação. Apresentava ainda prurido, lacrimejamento, zumbido e parestesia. O quadro da paralisia de Bell do tipo periférica, previamente diagnosticado, caracterizou-se pela impossibilidade de oclusão voluntária das pálpebras do lado direito, paralisia dos mús culos orbiculares da boca, risório e bucinador. Associado a essa patologia, o paciente recebeu o diagnóstico de disfunção temporomandibular do tipo mialgia mediada centralmente. A conduta terapêutica adotada foi terapia oclusal, farmacoterapia, fisioterapia, fonoaudiologia e laserterapia. Após duas semanas o paciente obteve melhora significativa do quadro doloroso e estabilização da desordem muscular. Quanto à função motora do nervo facial, pequeno ganho foi observado na mímica facial do paciente. Considerações finais: A conduta terapêutica mostrou-se satisfatória e o paciente está em acompanhamento na instituição.

ABSTRACT

A terapia endodôntica nos dentes decíduos foi analisada por meio de 3.358 prontuários de crianças atendidas na Clínica de Odontopediatria da Faculdade de Odontologia da Universidade Federal do Rio de Janeiro (UFRJ), no período de 1990 a 2010. Os dados deste estudo retrospectivo foram tabulados no programa SPSS 16.0, e o protocolo da conduta clínica foi analisado por década (PI = 1990-2000; P2 = 2001-2010) utilizando-se o teste x(2). A média de idade das crianças foi de 4,5 ± 1,4 anos para a primeira década e de 5,5 ± 2,1 anos para a segunda década. Um dos principais motivos para o tratamento continua sendo a presença de cárie extensa (79,9%). Para a obturação dos condutos, no primeiro período, a pasta mais utilizada foi a proposta por Guedes-Pinto (76,5%), e no segundo, a pasta de óxido de zinco e eugenol (54,0%). Concluiu-se que não houve mudança significativa no protocolo das pulpectomias realizadas na Disciplina de Odontopediatria da Faculdade de Odontologia da UFRJ, embora tenham se observado pequenas variações nas técnicas utilizadas em relação ao material obturador

ABSTRACT

Objetivo: Avaliar a eficácia de pulpectomias com remoção de smear layer em dentes decíduos anteriores e as condições clínicas dos sucessores permanentes após cinco anos de acompanhamento clínico e radiográfico.Método: Foram selecionadas crianças com idade entre três a cinco anos, clinicamente saudáveis, com necessidade de tratamento do canal radicular em dentes anteriores decorrente de cárie e/ou traumatismo dento-alveolar. O preparo químico-mecânico consistiu da instrumentação com limas K e hipoclorito de sódio 1,0% e na irrigação final, o ácido cítrico a 6,0% foi utilizado para remoção da smear layer. Os condutos foram obturados com o cimento de OZE e todos os dentes restaurados com compósito fotopolimerizável. A avaliação clínica e/ou radiográfica ocorreu no primeiro mês e sucessivamente durante seis meses até cinco anos pós-tratamento ou até a erupção do sucessor permanente.Resultados: O índice de sucesso observado foi de 91,5%. Após cinco anos de acompanhamento, trinta e oito dentes permanentes sucessores (80,9%) estavam erupcionados. Destes, cinco (10,6%) elementos apresentaram erupção ectópica e cinco (10,6%) apresentaram opacidades no esmalte. Não foi observada associação entre o desfecho do tratamento (sucesso ou insucesso) e determinadas variáveis observadas, como o motivo da alteração pulpar, diagnóstico pulpar, presença de lesão periapical e extensão da obturação. Conclusão: Após cinco anos de acompanhamento, as pulpectomias de dentes decíduos anteriores com remoção de smear layer apresentaram alto índice de sucesso sugerindo que o uso do ácido cítrico favoreceu o desempenho da terapia. Foi observado um número reduzido de opacidades do esmalte e de erupção ectópica nos permanentes sucessores.


A partir dos resultados observados, recomenda-se a realização de novos estudos clínicos, preferencialmente controlados e randomizados, utilizando o mesmo protocolo e incluindo molares, a fim de comprovar a efetividade da remoção de smear layer nas pulpectomias de dentes decíduos


Objective: To evaluate the efficacy de pulpectomies with removal of smear layer in primary anterior teeth and the clinical conditions of the permanent successors after five years of clinical and radiographic follow up.Method: Clinically healthy children aged 3 to 5 years requiring root canal treatment in anterior teeth due to caries and/or dentoalveolar trauma were selected. The chemomechanical preparation consisted of instrumentation with K files and 1.0% sodium hypochlorite and final irrigation with 6.0% citric acid for removal of smear layer. The canalswere filled with ZOE and all teeth were restored with photoactivated composite resin. Clinical and/or radiographic evaluation was carried out in the first month and then successively during six months up to five years posttreatment or up to eruption of the permanent successor.Results: The success rate was 91.5%. After five years of follow up, 38 permanent successors (80.9%) had erupted. From these, 5 (10.6%) teeth erupted ectopically and five (10.6%) presented enamel opacities. There was no association between treatment outcome (success or failure) and certain factors, such as pulpal alteration, pulpal diagnosis, presence of periapical lesion and apical limit of obturation. Conclusion: After five years of follow up, the pulpectomies in primary anterior teeth with removal of smear layer presented a high success rate, suggesting that the use of citric acid was favorable to the therapy. There was a small number of enamel opacities and ectopic eruptions of the permanent successors. Based on the obtained results, it is recommended the development of new clinical studies, especially controlled and randomized trials, using the same protocol and including molars, in order to confirm the effectiveness of smear layer removal in the pulpectomies of primary teeth

ABSTRACT

The present study evaluated the antimicrobial activity of three root canal irrigants against Enterococcus faecalis, Candida albicans, and Staphylococcus aureus. These microorganisms were incubated in the presence of citric acid (6 and 10 percent), EDTA (17 percent), and NaOCl (0.5, 1.0, 2.5, and 5.25 percent). Agar diffusion tests were performed and redox indicator resazurin was used to evaluate the inhibitory effect of the irrigants on the metabolic activity of these microorganisms. The mean diameters of the inhibition zones for the C. albicans cultures were 11.6 mm (17 percent EDTA), 5.5 mm (0.5 percent NaOCl), 12.9 mm (1 percent NaOCl), 22.1 mm (2.5 percent NaOCl), and 28.5 mm (5.25 percent NaOCl). The mean diameters of the inhibition zones for E. faecalis were 2.8 mm (1 percent NaOCl), 5.4 mm (2.5 percent NaOCl), and 8.3 mm (5.25 percent NaOCl). For S. aureus, the mean values were 8.0 mm (17 percent EDTA), 3.0 mm (1 percent NaOCl), 8.8 mm (2.5 percent NaOCl), and 10.0 mm (5.25 percent NaOCl). Most of the irrigant solutions presented effective antimicrobial activity against C. albicans. A high inhibitory effect on the metabolic activity of E. faecalis was detected when the microorganisms were incubated with 17 percent EDTA. The same result was reached when S. aureus was incubated in the presence of > 2.5 percent NaOCl. Altogether, these results indicate that 2.5 percent and 5.25 percent NaOCl are microbicides against S. aureus while 0.5 percent and 1 percent NaOCl are only microbiostatic against the tested bacteria. The 6 percent and 10 percent citric acid as well as 17 percent EDTA did not affect the viability of any of the assayed microorganisms.

ABSTRACT

A Síndrome da Ardência Bucal é uma afecção intra-oral dolorosa complexa caracterizada pela sensação de queimação da mucosa bucal. Este trabalho objetiva apresentar o relato de uma paciente, sexo feminino, 87 anos de idade, leucoderma que compareceu ao o serviço de Estomatologia de Universidade pública de ensino superior em Odontologia do Rio de Janeiro - RJ com a queixa de queimação em língua há um ano sem nenhum fator iniciador, porém com aumento da intensidade ao consumir alimentos ácidos e ao longo do dia. Na anamnese referiu não apresentar desordens metabólicas ou fazer uso de medicamentos e no exame físico não foram observadas alterações orais que justificassem o quadro de ardência. A hipótese diagnóstica foi de síndrome da ardência bucal, confirmada através da ausência de achados clínicos e de alterações nos exames sorológicos solicitados. A conduta consistiu em aplicações de laser de baixa potência de forma pontual e em varredura na língua durante dois meses (15 sessões), período em houve estabilização do quadro, e remissão significativa do sintoma (escala visual analógica inicial = 8 e final = 2). Desta forma, o laserterapia mostrou-se uma alternativa terapêutica eficaz no tratamento deste caso de Síndrome da Ardência Bucal e ressalta-se a importância da exclusão de outras morbidades antes de concluir o diagnóstico desta entidade.


The Burning Mouth Syndrome is complex and painful intra-oral affection characterised by burning sensation of oral mucosa. This study is aimed at reporting a case of a 87-year-old Caucasian female patient who attended the stomatology service, at a public university in Rio de Janeiro, complaining that her tongue was "burning" for more than one year despite the absence of a cause, although such a sensation worsened during consumption of acid food as well as over the day. In the anamnesis, she reported no metabolic disorders or use of medications, and no oral alteration explaining such burning symptoms was observed on clinical examination. The diagnostic hypothesis was burning mouth syndrome, which was confirmed because of the absence of both clinical findings and serological changes in the exams. The procedure consisted of applying low-level laser on the tongue in punctual and scanning modes during two months (15 sessions), period in which the clinical picture become stable and significant remission of the symptom was observed (initial and final analogical visual scales = 8 and 2, respectively). In this way, laser therapy was shown to be an efficient therapeutic alternative in the treatment of the present case of Burning Mouth Syndrome, thus emphasising the importance of ruling out other morbidities prior to considering the diagnosis of this condition.

ABSTRACT

Objetivo: Avaliar o efeito citotóxico de diferentes concentrações de hipoclorito de sódio sobre uma cultura de células de osteoblastos humanos (linhagem HOB). Métodos: Culturas confluentes de osteoblastos humanos (linhagem HOB) foram obtidas em meio de Dulbecco modificado, suplementado com 10% de soro fetal bovino e submetidas a incubações com hipoclorito de sódio (concentrações de 0,5; 1,0; 2,5 e 5,25%) durante trinta segundos. O grupo controle foi representado por células incubadas em fosfato de potássio. A avaliação da viabilidade celular foi realizada através do teste de exclusão com azul de Trypan, em triplicata. Durante o período de incubação, imagens foram registradas através de um microscópio óptico invertido, para avaliação da morfologia celular. Resultados: Verificou-se que no grupo controle havia 98,7% de células viáveis, morfologicamente normais, enquanto que nos grupos experimentais, células viáveis não foram observadas. A cinética de citotoxidade seguiu tendência dependente da concentração. Conclusão: O hipoclorito de sódio nas concentrações 0,5; 1,0; 2,5; 5,25%, incubado por trinta segundos em cultura de osteoblastos humanos é citotóxico.


Objective: To evaluate the cytotoxic effect of different amounts of sodium hypochlorite, on a culture of human osteoblastos (HOB) cells. Method: Cultures of human osteoblasts (HOB) in Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% of bovine fetal serum were incubated in sodium hypochlorite (concentrations of 0.5; 1.0; 2.5 and 5.25%) for thirty seconds. The control group was represented by cells incubated in phosphate buffered saline (PBS). Cell viability was assessed by means of 0.4% trypan blue dye exclusion test, in triplicate. During the incubation period, images were recorded through an inverted optic microscope to evaluate the cellular morphology. Results: In the control group 98.7% of viable cells were verified, without morphology alterations, while no viable cells were observed in the experimental groups. The kinetics of cytotoxity was concentration-dependent. Conclusion: It was concluded that there was a cytotoxic effect on cultures of human osteoblasts incubated for thirty seconds in sodium hypochlorite in all concentrations (0.5; 1.0; 2.5 and 5.25%).
