Evaluating the efficacy of Etoricoxib in reducing post-operative pain associated with minor oral surgery. A randomized clinical trial / Avaliação da eficácia do Etoricoxibe na redução da dor pós-operatória associada à cirurgia oral menor: ensaio clínico randomizado

Etoricoxib, a new cyclooxygenase-2-selective inhibitor has demonstrated a rapid onset analgesic effect for relieving acute pain especially when prescribed as a pre-emptive medication. On these bases, this study may provide useful information and guidance for clinicians working in the field of oral surgery, as regards handling odontogenic pain and postoperative pain precisely with cyclooxygenase-2 inhibitors. Objective: the study aimed to measure the quantifiable efficacy of Etoricoxib in reducing post-extraction pain in subjects undergoing minor oral surgical intervention as compared to Naproxen (a traditional NSAID) which is commonly used to control postoperative pain. Material and Methods: a 120 mg film-coated tablet of Etoricoxib was given to each of the twenty patients representing the study group, and a 500 mg tablet of Naproxen was given to each of the other twenty subjects representing the positive control group. According to manufacturer instructions, the tablets were given to the subjects 30 minutes pre-operatively (before dental extraction). Post-operative pain was assessed for each subject using eleven points from zero to ten, visual analog scale. Results: showed no statistically significant difference between Etoricoxib and Naproxen in decreasing post-extraction odontogenic pain, suggesting that Etoricoxib is as efficient as Naproxen in the control of discomfort with dental origin taking into consideration the patient's status when prescribing the medication. Conclusion: this study suggests that Etoricoxib can be handled as a pre-emptive medication to reduce post-operative pain for subjects seeking traditional or surgical extraction of any of their teeth (AU)

O Etoricoxibe, um novo inibidor seletivo da ciclooxigenase-2, demonstrou um efeito analgésico de início rápido para aliviar a dor aguda, especialmente quando prescrito como medicação preventiva. Com base nesses fundamentos, este estudo pode fornecer informações úteis e orientação para clínicos que trabalham no campo da cirurgia oral, no que diz respeito ao manejo da dor odontogênica e da dor pós-operatória de forma precisa com inibidores da ciclooxigenase-2. Objetivo: o estudo teve como objetivo medir a eficácia quantificável do Etoricoxibe na redução da dor pós-extração em indivíduos submetidos a intervenção cirúrgica oral menor, comparado ao Naproxeno (AINE tradicional) que é comumente usado para controlar a dor pós-operatória. Material e Métodos: um comprimido revestido com um filme de 120 mg de Etoricoxibe foi administrado a cada um dos 20 pacientes representando o grupo de estudo, e um comprimido de 500 mg de Naproxeno foi administrado a cada um dos outros vinte sujeitos representando o grupo de controle positivo. De acordo com as instruções do fabricante, os comprimidos foram administrados aos indivíduos 30 minutos antes da cirurgia (antes da extração dentária). A dor pós-operatória foi avaliada para cada sujeito usando uma escala analógica visual de onze pontos, de zero a dez. Resultados: não mostraram diferença estatisticamente significativa entre o Etoricoxibe e o Naproxeno na diminuição da dor odontogênica pós-extração, sugerindo que o Etoricoxibe é tão eficiente quanto o Naproxeno no controle do desconforto de origem dentária, levando em consideração o estado do paciente ao prescrever a medicação. Conclusão: este estudo sugere que o Etoricoxibe pode ser administrado como medicação preventiva para reduzir a dor pós-operatória em indivíduos que buscam extração dentária tradicional ou cirúrgica de qualquer um de seus dentes.

Objective: The present study aimed to evaluate the quality of life in TMD patients with the use of Stabilization Splints (SSs) and Home Therapeutic Exercises (HTEs) guidance. Material and Methods: The study was a clinical, randomized, controlled, prospective, and interventional trial. The screening included dentate patients of both genders, diagnosed with TMD through the RDC/TMD questionnaire with no TMJ osteoarthritis and/or osteoarthrosis. To assess the quality of life, the Short-Form Health Survey (SF-36) questionnaire was applied to all patients (n=70), randomized into a test group with SS and a control group with HTE. The evaluations of both questionnaires were performed before and after the intervention of 12 weeks. Results: The comparisons between pre- and post-intervention intragroups were performed by the non-parametric Wilcoxon test with a 5% significance level. There was a frequency distribution of the responses to the 36 items of the SF-36 questionnaire and comparisons between times. In the test group, 49 patients received a SS and did HTEs. In the control group, 21 patients performed HTEs. In the statistical analysis, among the eight domains, three were identified with significant scores: pain, mental health, and vitality. Conclusion: It was found that there was an improvement in pain and quality of life after the treatment of TMD with a SS and HTE (AU)

Objetivo: O presente estudo teve como objetivo avaliar a qualidade de vida em pacientes com DTM com o uso de placas de estabilização (SSs) e orientação de exercícios terapêuticos domiciliares (HTEs). Material e Métodos: O estudo foi um ensaio clínico, randomizado, controlado, prospectivo e intervencionista. A triagem incluiu pacientes dentados de ambos os sexos, diagnosticados com DTM através do questionário RDC/TMD sem osteoartrite e/ou osteoartrose da ATM. Para avaliar a qualidade de vida, o questionário Short-Form Health Survey (SF-36) foi aplicado a todos os pacientes (n=70), randomizados em grupo teste com SS e grupo controle com HTE. As avaliações de ambos os questionários foram realizadas antes e após a intervenção de 12 semanas. Resultados:As comparações intragrupos pré e pós-intervenção foram realizadas pelo teste não paramétrico de Wilcoxon com nível de significância de 5%. Houve distribuição de frequência das respostas aos 36 itens do questionário SF-36 e comparações entre os tempos. No grupo controle, 21 pacientes realizaram HTEs. Na análise estatística, dentre os oito domínios, três foram identificados com escores significativos: dor, saúde mental e vitalidade. Conclusão: Verificou-se que houve melhora da dor e da qualidade de vida após o tratamento da DTM com SS e HTE.(AU)

A new preheating thermoviscous composite for restoration of non-carious cervical lesions: a 6-month randomized clinical trial / Um novo compósito termoviscoso de pré-aquecimento para restauração de lesões cervicais não cariosas: ensaio clínico randomizado de 6 meses

Objetivo: Este ensaio clínico randomizado, duplo-cego e boca dividida avaliou o desempenho clínico de um novo compósito termoviscoso com pré-aquecimento (PHT) em comparação com uma resina composta sem aquecimento (NHT) em restaurações de lesões cervicais não cariosas (LCNCs) durante um período de 6 meses. Material e Métodos: 120 restaurações foram realizadas em LCNCs com dois materiais restauradores (n = 60). Após a profilaxia, os dentes foram isolados com isolamento de fio retrator/rolos de algodão e um adesivo universal foi aplicado na estratégia de condicionamento seletivo do esmalte. Para o grupo PHT o aquecimento foi realizado a 68°C usando um aquecidor de bancada por 3 min. Por outro lado, para o grupo NHT, nenhum aquecimento foi aplicado. Ambos os materiais restauradores foram colocados no dispensador de cápsulas e inseridos nas LCNCs. Após 6 meses, o desempenho clínico das restaurações foi avaliado de acordo com os critérios FDI. A análise estatística foi realizada com teste Qui-quadrado para todos parâmetros da FDI (α = 0,05). Resultados: Apenas três restaurações no grupo NHT foram perdidas/fraturadas após seis meses de acompanhamento. As taxas de retenção (intervalo confiança 95%) por seis meses foram de 97,5% (88,6% - 99,0%) para o grupo NHT e 100% (93,9% - 100%) para o grupo PHT (p > 0,05). Vinte e duas restaurações (8 para NHT e 14 para PHT) apresentaram pequenos defeitos de adaptação marginal aos seis meses de acompanhamento (p > 0,05). Vinte e seis restaurações apresentaram alguma retenção de biofilme aos seis meses de acompanhamento (11 para NHT e 15 para PHT; p > 0,05). Em relação a todos os outros parâmetros de FDI avaliados, todas as restaurações foram consideradas clinicamente aceitáveis. Conclusão: O desempenho clínico do novo compósito termoviscoso de pré-aquecimento mostrou-se promissor após 6 meses de avaliação clínica quando aplicado em LCNCs.(AU)

Objective: This double-blind, split-mouth randomized clinical trial evaluate the clinical performance of a new preheating (PHT) thermoviscous composite compared to a non-heating (NHT) composite resin in restorations of non-carious cervical lesions (NCCLs) over a period of 6-month. Material and Methods: 120 restorations were performed on NCCLs with two restorative materials (n = 60). After prophylaxis, the teeth were isolated with retraction cord isolation/cotton rolls and one universal adhesive was applied in the selective enamel etching strategy. For the PHT group heating was carried out at 68°C using a heater bench for 3 min. On the other side, for the NHT group, no heating was applied. Both restorative materials were placed in the caps dispenser and inserted in the NCCLs. The restorations were evaluated after 6-month of clinical performance according to the FDI criteria. Statistical analysis was performed with Chi-square test for all FDI parameters (α = 0.05). Results: Three restorations only in the NHT group were lost/fractured after six months follow-up. The retention rates (confidential interval 95%) for six months were 97.5% (88.6% - 99.0%) for the NHT group and 100% (93.9% - 100%) for the PHT group (p > 0.05). Twenty-two restorations (8 for NHT and 14 for PHT) presented small marginal adaptation defects at the six-months follow-up (p > 0.05). Twenty-six restorations were found to have biofilm retention in the six-month recall (11 for NHT and 15 for PHT; p > 0.05). Regarding all others FDI parameters evaluated, all restorations were considered clinically acceptable. Conclusion: The clinical performance of the new preheating thermoviscous was found to be promise after 6-month of clinical evaluation when applied in NCCLs (AU)

Radiopacidad de Resinas Acrílicas y Bisacrílicas Usadas como Restauraciones Provisionales / Radiopacity of Acrylic and Bisacrylic Resins Used as Provisional Restorations

Una adecuada radiopacidad de los materiales para restauraciones provisorias permite su evaluación en el examen radiográfico. Sin embargo, existe gran desconocimiento sobre el cumplimiento de los requerimientos establecidos por la norma ISO 4049. El objetivo del siguiente estudio fue determinar la radiopacidad de los materiales para provisionalización presentes en el mercado nacional y corroborar si estos cumplen con el valor mínimo requerido por la normativa. Se realizó un estudio experimental in vitro, en el cual se prepararon muestras en forma de discos de 10 mm de diámetro y 1 mm de espesor de resinas acrílicas: Acrílico Autocurable (Marché®), Duralay (Reliance), Caulkâ (Dentsply), ALIKE™ (GC) y resinas bisacrílicas: Protemp™4 (3M, 2008), LuxatempStar (DMG), Luxacrown (DMG), Structur Premium (VOCO), ExperTemp™ (Ultradent) y Acrytemp (Zhermack). Las muestras fueron radiografiadas junto a una cuña de aluminio escalonada. Las imágenes fueron analizadas para determinar el valor en escala de grises y su respectivo valor en mm de aluminio. Los datos fueron analizados para verificar si cumplen con la normativa ISO. Se encontraron diferencias estadísticamente significativas. La radiopacidad equivalente de las resinas acrílicas en mm de Al en orden descendente fue de 0,85 ± 0,08 para ALIKE™, 0,72 ± 0,32 para acrílico Marché®, 0,65 ± 0,25 para Caulkâ y 0,56 ± 0,05 para Duralay, siendo todos menores a lo requerido por la norma. La radiopacidad equivalente de las resinas bisacrílicas fue de 1,75 ± 0,2 para Acrytemp, 1,51± 0,27 para Luxacrown, 1,47 ± 0,14 para Structur Premium, 1,43 ± 0,23 para LuxatempStar, 1,02 ± 0,28 para Protemp™4 y 1± 0,1 para ExperTemp™, los cuales son mayores a lo exigido por la norma. En conclusión, las resinas bisacrílicasevaluadas en este estudio cumplen con el requisito de radiopacidad exigido, a diferencia de las acrílicas que no lo cumplen.

An adequate radiopacity of materials for provisionalization allows its proper evaluation on the radiographicexam. However, there is a lack of knowledge about compliance with the requirements established by the ISO 4049 norm. The aim of this study was to determine the radiopacity of provisionalization materials available in the national market and verify if they comply with the minimum requirements of ISO regulations. An in vitro experimental study was carried out, samples of 10 mm in diameter and 1 mm thickness of acrylic resins: Self-Cure Acrylic (Marché®), Duralay (Reliance), Caulkâ (Dentsply), Alike™ (GC) and by sacrilic resins: Protemp™4 (3M), Luxatemp Star (DMG), Luxacrown (DMG), Structur Premium (VOCO), ExperTemp™ (Ultradent), Acrytemp (Zhermack) were prepared. The samples were x-rayed together with a stepped aluminum wedge. The images were analyzed to determine the gray scale value and its equivalent value in mm of Aluminum. The data was analyzed to verify compliance with the ISO standard. Statistically significant differences were found. The equivalent radiopacity of acrylicresins in mm of Al in descending order was 0.85± 0.08 for ALIKE™, 0.72 ± 0.32 for acrylic Marché®, 0.65 ± 0.25 forCaulkâ and 0.56 ± 0.05 forDuralay, all being less than the required by norm. The equivalent radiopacity of by sacrilic resins was 1.75 ± 0.2 for Acrytemp, 1.51± 0.27 for Luxacrown, 1.47 ± 0.14 for Structur Premium, 1.43 ± 0.23 for LuxatempStar, 1.02 ± 0.28 forProtemp™4 and 1± 0.1 forExperTemp™,which are greater than the requirements. In conclusion, the bisacrylic resins evaluated in this study comply with the radiopacity standard, however the acrylic resins evaluated do not comply.

Contaminación Bacteriana del Aerosol Dental con y sin Uso de una Cúpula de Acrílico en un Paciente en Pandemia COVID-19 / Bacterial Contamination of Dental Aerosol with and Without Use of an Acrylic Dome in a Patient in COVID-19 Pandemic

En la actual pandemia por COVID-19, el mundo clínico se ha visto obligado a reforzar el uso de protección en el quehacer asistencial, debido al alto grado de contagio y virulencia de este virus. En odontología, debido a la producción de aerosoles, se han suspendido las atenciones clínicas para prevenir contagios. El objetivo de esta investigación es determinar la cantidad de contaminación bacteriana, generada por el uso de aerosol con micromotor de alta velocidad, realizado por dentistas del Hospital de La Florida, Santiago de Chile. El estudio contó con 10 pacientes por box, con 2 muestras por paciente, en total 40 placas de cultivo, 20 Control, 20 Prueba y 3 Ambientales. El medio de cultivo se mantuvo por 10 minutos, ubicado en la frente del ope rador y pechera del paciente, se realizó simulación de operatoria con turbina, sin aislamiento absoluto, con y sin uso de una cúpula de acrílico, puesta en un paciente sano. Las muestras fueron analizadas macroscópicamente, incubadas a 37 ºC en una atmósfera de oxígeno por 24 horas y dióxido de Carbono a las 48 horas. 43 placas fueron positivas, observándose, en las muestras de la peche ra una diferencia no significativa (p=0,753) entre ambos grupos, con una diferencia promedio de 56,76 UFC. En las placas de la fre nte del operador, un promedio de 8.1 UFC en Box sin cúpula y 3,9 UFC en el box con cúpula, encontrándose diferencia estadísticament e significativa (p= 0,0391). Las placas ambientales 28,33 UFC en el Box con cúpula, 29 UFC en el Box control y Box sin cúpula 46, 66 UFC. Al comprobar que la cúpula de acrílico contiene eficazmente los aerosoles, corresponde utilizarlo como norma de biosegurid ad para proteger tanto al equipo dental, como a los pacientes en tiempos de pandemia contra el COVID-19.

In the current PANDEMIC for COVID- 19, the clinical world has been forced to reinforce the use of protection in healthcare, due to the high degree of contagion and virulence of this virus. In dentistry, due to the production of aerosols, clinical care has been suspended to prevent infection. The objective of this research is to determine the amount of bacterial contamination, generated by the use of high-speed micromotor aerosol, carried out by dentists at the Hospital de La Florida, Santiago, Chile. The study included 10 patients per box, with 2 samples per patient, in total 40 culture plates, 20 Control, 20 Test and 3 Environmental. The culture medium was kept for 10 minutes, located in the front of the operator and the patient's chest. Simulation of the operation with a turbine was performed, without absolute isolation, with and without the use of an acrylic dome, placed on a healthy patient. The samples were analyzed macroscopically, incubated at 37ºC in an atmosphere of oxygen for 24 hours and Carbon dioxide after 48 hours. 43 plates were positive, noting a non-significant difference (p = 0.753) between the two groups in the bib samples, with an average difference of 56.76 CFU. In the plates of the operator's forehead, an average of 8.1 CFU in the box without dome and 3.9 CFU in the box with dome, finding a statistically significant difference (p = 0.0391). The environmental plates 28.33 UFC in the Box with the dome, 29 UFC in the Control Box and the Box without dome 46.66 UFC. When verifying that the acrylic dome effectively contains aerosols, it should be used as a biosafety standard to protect both dental equipment and patients in times of pandemic against COVID-19.

Influence of viscosity and chemical composition of composite resins in non-carious cervical restorations: 12-month randomized clinical trial / Influência da viscosidade e composição química das resina compostas em restaurações de lesões cervicais não-cariosas: resultados de 12 meses de uma pesquisa clínica randomizada

Objective: The objective of this double-blind, randomized controlled clinical trial was to evaluate the clinical performance of two methacrylate-based flowable composite and ormocer-based flowable composite in non-carious cervical lesions (NCCLs) of adult patients. Material and Methods: 183 restorations were performed on NCCLs using the Futurabond U adhesive system, applied in the selective enamel etching mode in all cavities. After the adhesive application, the cavities were restored with one out of the three evaluated flowable composites (n = 61 per group): ormocer-based flowable composite (Admira Fusion Flow, ORM), low viscosity methacrylate-based composite (GrandioSO Flow, LV) and high viscosity methacrylate-based composite (GrandioSO Heavy Flow, HV). After 12 months of clinical performance, these restorations were evaluated according to FDI and USPHS criteria in the following items: retention/fracture, marginal adaptation, marginal staining, postoperative sensitivity and caries recurrence. Results: eight restorations were lost/fractured after 12 months of clinical evaluation (1 in the ORM and 7 in the HV group). The retention rates for 12- months (95% confidence interval) were 98.4% (91.3%-99.7%) for the ORM group, 100% (94.5%-100%) for the LV group and 88.5% (78.1%-94.3%) for the HV group, with no statistical difference identified between any pair of groups (p > 0.05). Five restorations presented small marginal adaptation defects at the 12-months evaluation recall, and all of them were considered clinically acceptable. Conclusion: The clinical performance of the universal adhesive associated to ormocer-based or methacrylate-based flowable composite were found to be promising after 12-month of clinical evaluation (AU)

Objetivo: O objetivo deste estudo clínico duplo-cego randomizado foi comparar as taxas de retenção de um compósito fluido à base de Ormocer versus dois compósitos fluidos à base de metacrilato quando utilizados em lesões cervicais não cariosas (LCNCs) de pacientes adultos. Material e Métodos: 183 restaurações foram realizadas em LCNCs utilizando o sistema adesivo Futurabond U, aplicado no modo de condicionamento seletivo do esmalte em todas as cavidades. Após a aplicação do adesivo, as cavidades foram restauradas com um dos três compósitos fluidos avaliados (n = 61 por grupo): compósito fluido à base de ormocer (Admira Fusion Flow, ORM), compósito à base de metacrilato de baixa viscosidade (GrandioSO Flow, LV) e compósito à base de metacrilato de alta viscosidade (GrandioSO Heavy Flow, HV). Após 12 meses de desempenho clínico, essas restaurações foram avaliadas de acordo com os critérios FDI e USPHS nos seguintes itens: retenção / fratura, adaptação marginal, coloração marginal, sensibilidade pós-operatória e recorrência de cárie. Resultados: oito restaurações foram perdidas / fraturadas após 12 meses de avaliação clínica (1 no grupo ORM e 7 no grupo HV). As taxas de retenção por 12 meses (intervalo de confiança de 95%) foram 98,4% (91,3% -99,7%) para o grupo ORM, 100% (94,5% -100%) para o grupo LV e 88,5% (78,1% -94,3%) para o grupo HV, sem diferença estatística identificada entre nenhum par de grupos (p> 0,05). Cinco restaurações apresentaram pequenos defeitos de adaptação marginais no período de avaliação de 12 meses, e todas foram consideradas clinicamente aceitáveis. Conclusão: O desempenho clínico do adesivo universal associado ao compósito fluido à base de ormocer ou metacrilato mostrou-se promissor após 12 meses de avaliação clínica(AU)

Supervivencia de implantes dentales y complicaciones intra y posoperatorias en elevación de seno maxilar con ventana lateral e implante dental simultáneo en rebordes con reabsorción severa / Survival of dental implants and intra and post operative complications in elevation of the maxillary sinus with side window and simultaneous dental implant in sever resorbed RIMS

Objetivo: El posicionamiento de implantes dentales simultáneo a la elevación del seno maxilar en rebordes con reabsorción ósea severa (≤4 mm) es una técnica quirúrgica que disminuye los tiempos operatorios. Sin embargo, es considerada sensible por ser dependiente del operador y, en el caso que no se dé un manejo adecuado, puede presentar complicaciones. En este estudio se realiza una revisión de la literatura sobre la supervivencia de los implantes dentales y las complicaciones intra y posoperatorias en procedimientos de elevación del seno maxilar con la colocación simultánea de implante dental en rebordes con reabsorción ósea severa. Materiales y métodos: Se realizó una búsqueda bibliográfica de la literatura publicada en los últimos 10 años, durante el periodo de mayo y junio del 2019, en las bases de datos Medline­PubMed, EBSCOhost y Scopus. Esta se complementó con una búsqueda manual en revistas especializadas en periodoncia y cirugía oral Q1, posicionadas en el top 5 del 2018 en www.scimagojr.com. Se incluyeron ensayos clínicos y estudios prospectivos y retrospectivos. Se identificó 2562 artículos científicos. Tras el análisis de los títulos, la lectura de los resúmenes y los textos completos, se seleccionaron 6 artículos para el análisis de la técnica quirúrgica y 35 para complementar la información. Conclusiones: La colocación simultánea de implantes dentales a la elevación del seno maxilar es una de las técnicas utilizadas para restituir la función en el maxilar posterior. La complicación intraoperatoria más frecuente es la perforación de la membrana sinusal y la posoperatoria es la infección asociada con perforación de la membrana, o la migración del implante al seno maxilar. La supervivencia promedio del implante observada en los estudios es mayor al 94%. (AU)

Aim: The positioning of dental implants simultaneous to the elevation of the maxillary sinus in ridges with severe bone resorption (≤4mm) is a surgical technique that reduces operative times. However, it is considered sensitive, being dependent on the operator, and in the absence of appropriate handling, complications can occur. This study aimed to provide a review of the literature on the survival of dental implants and intra- and post-operative complications in maxillary sinus lift procedures with the simultaneous placement of a dental implant in ridges with severe bone resorption. Materials and methods: A bibliographic search of the literature published in the last 10 years in the Medline-Pubmed, EBSCO HOST and SCOPUS databases was carried out from May to June 2019. This was complemented with a manual search in journals specialized in Periodontology and Oral Surgery Q1, positioned in the Top 5 of the year 2018 at www.scimagojr.com. Prospective, retrospective and clinical trials were included 2562. A total of 2562 prospective, retrospective and clinical trials were included. After analyzing the titles and reading the abstracts and full texts, 6 articles were selected for analysis of the surgical technique and 35 to complement information. Conclusions: The placement of dental implants simultaneously with maxillary sinus elevation is one of the techniques used to restore function in the posterior maxilla. The most frequent intra-operative complication is perforation of the sinus membrane, and the most common post-operative complication is infection associated with perforation of the membrane, or migration of the implant to the maxillary sinus. The average implant survival reported is greater than 94%. (AU)

Evaluation of Internal bleaching with 35% hydrogen peroxide in dentin conditioned with 37% phosphoric acid and 17% EDTA / Evaluación del blanqueamiento interno con peróxido de hidrógeno al 35% en dentina acondicionada con ácido fosfórico al 37% y EDTA al 17%

Introduction: This study aimed to evaluate the effect of dentin surface treatment with 37% phosphoric acid or 17% ethylenedia-minetetraacetic acid (EDTA) before Internal Bleaching with 35% hydrogen peroxide using the walking bleach technique. Material and Methods: This experimental in vitro study used 66 human premolars extracted for orthodontic reasons, which were debrided, endodontically prepared, and pigmented with chromogens derived from blood decomposition. The samples were randomly divided into three groups (n=22). Group A: bleaching agent without dentin conditioning; group B: bleaching agent in dentin conditioned with phosphoric acid 37%; group C: bleaching agent in dentin conditioned with 17% EDTA. 4 applications of bleaching agent were used with a separation of 4 days between each session. The initial color (baseline) and after each application was determined by spectrophotometry, recording the CIE L*a*b* values and the total color variation between the initial parameters and the different evaluation times. Results: Data were statistically analyzed with the Wilcoxon test. This showed statistically significant differences for the total variation of the color between the study groups, with the control group in no case inferior to the rest. Conclusion: The application of 37% phosphoric acid increased the effectiveness of the bleaching agent when compared to 17% EDTA. However, these did not increase the effectiveness compared to the application of the bleaching agent without a previous dentin surface treatment.

Introducción: El objetivo de este estudio fue evaluar el efecto del tratamiento de superficie dentinaria con ácido fosfórico al 37% o EDTA al 17% previo al blanqueamiento Interno con peróxido de hidrógeno al 35% por medio de la técnica Walking Bleach. Material y Métodos:Para este estudio experimental in vitro, se utilizaron 66 premolares humanos extraídos por indicación ortodóncica, los cuales fueron desbridados, preparados endodónticamente, y pigmentados con cromógenos derivados de la descomposición sanguínea.

Resultados: Los datos fueron analizados estadísticamente con la prueba de Wilcoxon, arrojando diferencias estadísticamente significativas para la variación total del color entre los grupos de estudio, siendo en ningún caso el grupo control inferior al resto. Conclusión: La aplicación de ácido fosfórico al 37% aumenta la eficacia del agente blanqueador al compararlo con el EDTA 17%, sin embargo, no aumentan la eficacia respecto a la aplicación del agente blanqueador sin un tratamiento de superficie dentinaria previo.

Alternative of Lower-Cost Glass-Ionomer Sealant in the Prevention of Caries Lesions in Brazilian Children

Objective: To compare retention, preventive effectiveness and longevity of two different highviscosity glass-ionomer sealants Ketac Molar® and Maxxion R® in the sealing of erupting and out-of-occlusion first permanent molar in children aged 5-7 years. Material and Methods: Children with past caries experience with healthy erupting first permanent molar were included in the study. Teeth 16 and 46 were sealed with Ketac Molar® and teeth 26 and 36 were sealed with Maxxion R®. After 8 months, the retention of sealants was evaluated using the following criteria: total retention; presence of sealant in two thirds of the occlusal surface; presence of sealant in one third of the surface; and total absence of the sealant. Results: Statistical difference between materials was observed, and Ketac Molar® retention was superior to that of Maxxion R® (p<0.05). Regarding the development of caries in sealed first permanent molar, none of the teeth sealed with Ketac Molar® or Maxxion R® developed caries lesion. Conclusion: Ketac Molar® retention is significantly superior to that of Maxxion R®, but the preventive effectiveness in the development of carious lesions is similar for both, which is extremely interesting for the field of public health, since the cost of the material is significantly lower.

Resistencia compresiva de dientes con conductos amplios restaurados con dos técnicas / Compressive resistance of teeth with large conducts restored with two techniques

RESUMEN: Objetivo: Comparar la resistencia compresiva de dientes premolares uniradiculares, tratados endodónticamente restaurados mediante la técnica de monobloque y complementación. Materiales y métodos: Se seleccionaron 45 premolares inferiores unirradiculares, los cuales fueron distribuidos aleatoriamente en 3 grupos, según el diseño reconstructivo: monobloque y complementación; el tercer grupo restaurado bajo la técnica de núcleo colado fue utilizado como grupo control. Para determinar diferencias en la resistencia a la fractura, se realizó un análisis de Varianza (ANOVA a una Vía) y test post hoc de Bonferroni. Resultados: El promedio de la resistencia fue mayor en el grupo dientes rehabilitados con la técnica convencional, seguido de la técnica de monobloque, y en tercer lugar encontramos la técnica de complementación con el valor más bajo. Sin embargo, las técnicas de monobloque y complementación presentan resistencias similares. Conclusiones: La resistencia a la fractura de dientes restaurados con pernos colados es mayor a la de los restaurados con pernos prefabricados fibras de vidrio con técnicas de complementación y monobloque. Sin embargo, producen mayor cantidad de fallas no reparables o de mal pronóstico que los dientes restaurados con pernos prefabricados de fibras de vidrio por su módulo elástico.

ABSTRACT: Objective: To compare the compressive strength of single-rooted premolar teeth, treated endodontically and restored using the monoblock technique and complementation. Materials and methods: 45 single-rooted inferior premolars were selected, which were randomly distributed in 3 groups, 2 according to the reconstructive design: monoblock and complementation; the third group, restored under the cast core technique, was used as a control group. To determine differences in fracture resistance, we performed an analysis of Variance (One-way ANOVA) and post hoc Bonferroni test Results: The mean resistance was higher in the group rehabilitated with the conventional technique, followed by the monoblock technique, and thirdly the technique of complementation with the lowest value. However, the monoblock and complementation techniques exhibited similar strengths. Conclusions: Restored teeth with cast posts have a greater resistance to fracture than restorations with prefabricated posts, glass fibers with complementation and monoblock techniques. However, they produce more non-repairable or poor prognostic failures than restored teeth with prefabricated glass fiber posts for their elastic modulus.

Influence of Functional Clinical Temperature over Compressive Strength and Diametral Tensile Strength of Various Luting Cements

Objective: To estimate the effect of temperature over the physical properties of commonly used luting cements. Material and Methods: The two set of cylindrical shaped cement samples measuring 12mm X 6mm and 4mm X 8mm were fabricated from non-eugenol zinc oxide, glass ionomer, zinc phosphate, Zinc polycarboxylate, resin cements. These two sets of samples were utilized to test compressive and diametral tensile strength respectively. Forty cement samples from each mold were fabricated and distributed between 14, 22, 37 and 550C (N=10). The samples were tested under universal testing machine, and data subsequently analyzed using One-way ANOVA and Tukey multiple comparison's statistical methods at p > 0.05. Results: The higher temperature resulted in noticeable reduction in the compressive strength of non-eugenol -zinc oxide, Zinc-phosphate, Zinc poly carboxylate cements. The highest compressive strength was recorded for non-eugenol zinc oxide (8.08 Mpa) at 370C, Zinc phosphate (91.01Mpa) at 140C, and for zinc polycarboxylate (83.06 Mpa) at 370C. The comparative values for respective cements at 550C were 6.40Mpa, 59.80Mpa, and 52.88 Mpa. The higher temperature had insignificant effect on the compressive strength of glass ionomer cement, while composite resin cement indicated minor deterioration. Conclusion: The relative mouth temperature influences the physical properties of the luting cements.

Survival analysis of ART restorations in primary molars of preschool children: 1 year follow-up / Análise de sobrevivência de restaurações ART em molares decíduos de crianças com idade pré-escolar: acompanhamento de 1 ano

Among the minimally invasive approaches available today, the atraumatic restorative treatment (ART) has demonstrated promising results both in the primary and permanent dentition. Objective: To evaluate the survival of Class I ART restorations in preschoolers with two Brazilian brands of glass ionomer cements (GIC) in comparison with a reference GIC. Material and method: The cavities of 49 preschool children (three to five years) with carious lesions in the posterior teeth (N=81) were filled by two experienced pediatric dentists according to the ART technique. The Brazilian GICs Maxxion-R (MR) and Vitro-Fil LC (VF), and the reference GIC Ketac-Molar (KM) were placed in a randomly pre-established sequence. Restorations were evaluated after 6 and 12 months by another investigator. Scores 0 and 1 were considered successful, while scores 3-9 were classified as failures. Kaplan-Meier survival analysis and the log-rank test were performed (p<0.05). Result: No statistically significant differences in survival rates of the tested GIC were observed after 12 months. Conclusion: The clinical performance the low-cost Brazilian GICs MR and VF observed after 12 months suggests that they may be an alternative for Class I ART restorations to safeguard the natural exfoliation of primary teeth. However, until further studies involving a larger number of restorations and longer follow-up periods are conducted, reference GIC such as KM should continue to be the material of choice for ART restorations.

Dentre as abordagens minimamente invasivas atualmente disponíveis, o tratamento restaurador atraumático (ART) demonstra resultados promissores tanto na dentadura decídua quanto permanente. Objetivo: Avaliar a sobrevivência de restaurações ART Classe I, em pré-escolares, com duas marcas brasileiras de cimentos de ionômeros de vidro (CIV) em comparação com um CIV de referência. Material e método: Cavidades de 49 crianças pré-escolares (três a cinco anos de idade) com lesões cariosas nos dentes posteriores (N = 81) foram preenchidas por dois odontopediatras experientes, de acordo com a técnica ART. Os CIV brasileiros Maxxion-R (MR) e Vitro-Fil LC (VF) e o CIV de referência, Ketac-Molar (KM), foram inseridos em uma sequência pré-estabelecida aleatoriamente. As restaurações foram avaliadas após 6 e 12 meses por outro pesquisador. As pontuações 0 e 1 foram consideradas bem-sucedidas, enquanto as pontuações 3-9 foram classificadas como falhas. Foram aplicadas a análise de sobrevivência de Kaplan-Meier e o teste log-rank (p <0,05). Resultado: Não foram observadas diferenças estatisticamente significativas nas taxas de sobrevivência dos CIV testados após 12 meses. Conclusão: O desempenho clínico dos CIV brasileiros MR e VF, observado após 12 meses, sugere que estes podem ser uma alternativa para restaurações ART Classe I para proteger a esfoliação natural dos dentes decíduos. No entanto, até que sejam realizados estudos adicionais envolvendo um maior número de restaurações e períodos de acompanhamento mais longos, os CIV de referência, como o KM, devem continuar sendo o material de escolha para as restaurações ART.

Objetivo: Evaluar la longevidad de restauraciones de Tratamiento Restaurador Atraumático (TRA), utilizando dos mate-riales diferentes: un Cemento de Ionómero de Vidrio (CIV) de bajo costo y una Resina Compuesta de nanopartículas (RC), en cavidades ocluso-proximales de molares temporales. Materiales y métodos: Un total de 83 dientes fueron selecciona-dos en 43 niños de siete a diez años de edad, que presentaron al menos una lesión de caries ocluso proximal, en la ciudad de Cosmópolis / SP, Brasil. Los pacientes fueron asignados en dos grupos: CIV de bajo costo (Vitromolar - Nova DFL) y resina compuesta de nanopartículas (RC) (Filtek Z350 XT - 3M ESPE). Todos los procedimientos se realizaron de acuerdo con los principios del TRA. Las restauraciones fueron evaluadas después de 3, 6, 9 y 12 meses por un examinador entrena-do. Para verificar la tasa de sobrevida de las restauraciones utilizamos el análisis de sobrevida de Kaplan-Meier y la prueba de Log-Rank; y, para evaluar la asociación entre el resultado y las variables del paciente se aplicó la prueba de regresión de Cox. El nivel de significancia para todas las pruebas fue del 5%. Resultados: Después de 12 meses de seguimiento, la sobrevida global de las restauraciones fue de 75,3%. Las tasas de sobrevida del CIV y de la RC fueron 62.2% y 93.7%, respectivamente. El análisis estadístico mostró diferencias significativas entre los materiales, donde la RC tuvo un mejor desempeño (HR = 0.15, IC 0.03 a 0.68, p = 0.014) que el CIV de bajo costo. No se encontraron diferencias estadísticas para otras variables (p >0.05). Conclusión: La utilización de resina compuesta de nanopartículas en las restauraciones de TRA tuvo un mejor rendimiento en comparación con el cemento de ionómero de vidrio de bajo costo, después de una evaluación de 12 meses. Registro de prueba: REBEC (Registro Brasileño de Ensayos Clínicos) # RBR-8sw24r.

Objective: To evaluate the longevity of ART restorations using two different materials: a low-cost Glass Ionomer Cement (GIC) and nanoparticle Composite Resin (CR) in occlusal-proximal cavities of primary molars. Material and methods: A total of 83 teeth were selected among 43 children, aged seven to ten years old, which presented at least one multi-sur-face caries lesion, in the city of Cosmópolis/SP, Brazil. Patients were allocated into two groups: low cost GIC (Vitromo-lar ­ Nova DFL) and nanoparticle composite resin (CR) (Filtek Z350 XT ­ 3M ESPE). All procedures were performed according to ART guidelines. The restorations were evaluated after 3, 6, 9 and 12 months by a trained examiner. To verify the survival rate of the restorations we used Kaplan-Meier survival analysis and log-rank test. To evaluate the association between the outcome and patient variables was applied Cox regression test. The significance level for all tests was 5%. Results: After 12 months of follow-up, overall survival of the restorations was 75.3%. The GIC and CR survival rates were 62.2%, 93.7%, respectively. Statistical analysis showed significant differences between materials, where the CR performed better (HR = 0.15, CI 0.03 to 0.68; p = 0.014) than low cost GIC. No statistical differences were found for other variables (p >0.05). Conclusion: The use of nanoparticle composite resin in ART restorations performed better when compared to low cost glass ionomer cement after 12 months evaluation.

Effect of Sequential Use of 0. 2% Chlorhexidine Mouthwash and Listerine on Microbial Plaque Control

Objective: To evaluate the effects of combined and sequential consumption of chlorhexidine and listerine mouthwashes on plaque indices. Material and Methods: Sixteen dental students, both genders, were selected. After prophylaxis, four mouthwash regimens were used, such that in each period, mouthwash was used for 5 days and after each period there was 4 days of washing out. During the mouthwash period, the participants did not use any mechanical plaque control tool. The four regimens included: first regimen, first chlorhexidine then listerine; second regimen, listerine then chlorhexidine; third regimen, only listerine; fourth regimen, chlorhexidine alone. At the end of the period, individuals were evaluated for plaque indices and investigated for bleeding during probing using ANOVA variance analysis and post-hoc Tukey test. The level of significance was set at 5%. Results: Regimen 1 with a plaque mean of 0.55 ± 0.25 had significantly lower plaque than other regimens. The maximum rate of plaque was observed in regimen 3. Probing did not cause bleeding in any of the individuals who used the four mouthwash regimens. Conclusion: The use of 0.2% chlorhexidine and listerine has the highest effect on plaque reduction.
