ABSTRACT

Objective: This randomized controlled trial aimed to compare nanohydroxyapatite with fluoride on managing post ultrasonic scaling Dentine hypersensitivity (DH). Material and Methods: Thirty patients (aged 20-50 years) with post ultrasonic-scaling DH were included in this study. The sample was randomly divided into three equal groups of 60 teeth each: the first group received nanohydroxyapatite material, the second group received fluoride material and the third group received sterile water as a placebo (controls). The materials were applied once for each patient. All patients were instructed to rate the level of pain before treatment, and after 1 hour, 24 hours, 2 weeks and 1 month on the numerical rating scale (NRS). The Kruskal-Wallis test, Mann-Whitney tests, linear regression analysis were used for the statistical analysis. Significance level was set at 0.05. Results: Both nanohydroxyapatite and fluoride were successful in reducing pain associated with DH when compared with the placebo in subsequent follow-ups (p < 0.05). However, one-hour and one-day post application, nanohydroxyapatite could reduce hypersensitivity pain moreeffectively than fluoride (p < 0.05). Conclusion: Nanohydroxyapatite material was found to besignificantly more effective in reducing the DH that followed ultrasonic scaling one-hour and one-day post application as compared to fluoride and sterile water. Both fluoride and nanohydroxyapatite had similar effect on DH after two-weeks and one-month after application. (AU)


Objetivo: Este ensaio clínico randomizado teve como objetivo comparar a nano-hidroxiapatita com o flúor no manejo da hipersensibilidade dentinária (HD) pós-raspagem ultrassônica. Material e Métodos: Trinta pacientes (com idades entre 20-50 anos) com HD pós-raspagem ultrassônica foram incluídos neste estudo. A amostra foi dividida aleatoriamente em três grupos iguais com 60 dentes cada: o primeiro grupo recebeu material de nano-hidroxiapatita, o segundo grupo recebeu material de flúor e o terceiro grupo recebeu água esterilizada como placebo (controle). Os materiais foram aplicados uma vez para cada paciente. Todos os pacientes foram instruídos a avaliar o nível de dor antes do tratamento, e após 1 hora, 24 horas, 2 semanas e 1 mês na escala de avaliação numérica (NRS). Os testes de Kruskal-Wallis, Mann-Whitney e análise de regressão linear foram usados para a análise estatística. O nível de significância foi estabelecido em 0,05. Resultados: Tanto a nano- hidroxiapatita quanto o flúor foram bem-sucedidos na redução da dor associada à HD quando comparados ao placebo em acompanhamentos subsequentes (p <0,05). No entanto, 1 hora e 1 dia após a aplicação, a nano-hidroxiapatita pode reduzir a dor de hipersensibilidade de forma mais eficaz do que o flúor (p <0,05). Conclusão: O material da nano-hidroxiapatita foi significativamente mais eficaz na redução da HD que se seguiu à raspagem ultrassônica, 1 hora e 1 dia após a aplicação, em comparação com o flúor e a água estéril. Tanto o flúor, quanto a nano-hidroxiapatita apresentou efeito semelhante na HD após 2 semanas e 1 mês após a aplicação (AU)

ABSTRACT

Os lasers de diodo tornaram-se ferramentas clínicas populares devido ao seu tamanho compacto, acessibilidade, facilidade de uso e versatilidade. O objetivo deste artigo é apresentar as diversas aplicações de um laser de diodo na prática diária e destacar os aspectos técnicos do uso do laser de diodo para o mesmo. Esta série de casos relata o manejo de seis diferentes situações clínicas com laser de diodo: anquiloglossia, bolsa periodontal, zênites gengivais desiguais, mucocele, hipersensibilidade dentinária e gengiva hiperpigmentada. Os pacientes foram tratados com laser de diodo de 940 nm com potência de 0,5 W a 2 W dependendo do caso. A cicatrização pós-operatória transcorreu sem intercorrências na maioria dos casos e foram observados resultados favoráveis. O laser de diodo ofereceu vantagens cirúrgicas como ­ campo seco, desinfecção do sítio cirúrgico e cirurgia sem sutura. Além disso, os autores observaram melhor satisfação do paciente devido à mínima dor ou edema pós-operatório e alívio imediato em caso de hipersensibilidade dentinária. Este artigo apresenta as aplicações cirúrgicas e não cirúrgicas do laser de diodo juntamente com os aspectos técnicos. Embora a literatura disponível não forneça evidências substanciais para comparação direta do laser de diodo com as técnicas convencionais, é seguro concluir que o laser de diodo é uma ferramenta eficiente para uso rotineiro em odontologia.(AU)


The diode lasers have become popular clinical tools because of their compact size, affordability, ease of use and versatility. The aim of this paper is to put forth the various applications of a diode laser in day to day practice and highlight the technical aspects of diode laser use for the same. This case series reports management of six different clinical situations with diode laser namely ­ ankyloglossia, periodontal pocket, unequal gingival zeniths, mucocele, dentinal hypersensitivity and hyper-pigmented gingiva. The patients were treated with 940 nm diode laser with power settings from 0.5 W to 2 W depending on the case. The post-operative healing was uneventful in most cases and favourable outcomes were observed. The diode laser offered surgical advantages like ­ dry field, disinfection of surgical site and suture-less surgery. In addition, the authors observed better patient satisfaction owing to minimal post-operative pain or swelling and immediate relief in case of dentinal hypersensitivity. This paper presents both surgical and non-surgical applications of diode laser along with the technical aspects. Even though the available literature does not lend substantial evidence for direct comparison of diode laser with conventional techniques, it is safe to conclude that diode laser is an efficient tool for routine use in dentistry.(AU)

ABSTRACT

Abstract This clinical trial evaluated the effect of the coadministration of ibuprofen/caffeine on bleaching-induced tooth sensitivity (TS). A triple-blind, parallel-design, randomized clinical trial was conducted on 84 patients who received ibuprofen/caffeine or placebo capsules. The drugs were administered for 48 hours, starting 1 hour before the in-office bleaching. Two bleaching sessions were performed with 35% hydrogen peroxide gel with 1-week interval. TS was recorded up to 48 hours after dental bleaching with a 0-10 visual analogic scale (VAS) and a 5-point numeric rating scale (NRS). The color was evaluated with VITA Classical and VITA Bleachedguide scales (ΔSGU) and VITA Easyshade spectrophotometer (ΔE*ab and ΔE00). The absolute risk of TS in both groups was evaluated using Fischer's exact test. Comparisons of the TS intensity (NRS and VAS data) were performed by using the Mann-Whitney test and a two-way repeated measures ANOVA, respectively. The color alteration between the groups was compared with the Student's t test. The significance level was 5%. There was no statistically significant difference between the groups for the absolute risk of TS (p = 1.00) or for the intensity of TS (p > 0.05). A bleaching of approximately 7 shade guide units was observed on the Vita Classical and Vita Bleachedguide scales, with no statistical difference between the groups. It was concluded that coadministration of ibuprofen and caffeine did not reduce the absolute risk or intensity of TS and did not interfere with the efficacy of dental bleaching.


Resumo Este ensaio clínico avaliou o efeito da coadministração de ibuprofeno/cafeína na sensibilidade dental decorrente de clareamento (SD). Um estudo clínico randomizado, paralelo, triplo-cego, foi realizado em 84 pacientes que receberam cápsulas de ibuprofeno/cafeína ou placebo. Os fármacos foram administrados por 48 horas, começando 1 hora antes do clareamento em consultório. Duas sessões de clareamento foram realizadas com gel de peróxido de hidrogênio 35% com intervalo de 1 semana. A SD foi registrada até 48 horas após o clareamento dental com uma escala visual analógica (VAS) de 0-10 e uma escala de classificação numérica (NRS) de 5 pontos. A cor foi avaliada com as escalas Vita Classical e Vita Bleachedguide (ΔSGU) e com o espectrômetro Vita Easyshade (ΔE*ab e ΔE00). O risco absoluto de SD em ambos os grupos foi avaliado por meio do teste exato de Fischer. As comparações da intensidade da SD (NRS e VAS) foram realizadas utilizando-se o teste Mann-Whitney e uma ANOVA de dois fatores com medidas repetidas, respectivamente. A alteração de cor entre os grupos foi comparada com a o teste t de Student. O nível de significância foi de 5%. Não houve diferença estatisticamente significante entre os grupos para o risco absoluto de SD (p = 1,00) ou para a intensidade de SD (p > 0,05). Observou-se clareamento de aproximadamente 7 unidades nas escalas Vita Classical e Vita Bleachedguide, sem diferença estatística entre os grupos. Concluiu-se que a coadministração de ibuprofeno e cafeína não reduziu o risco absoluto ou intensidade da SD e não interferiu na eficácia do clareamento dental.

ABSTRACT

Introdução: A hipersensibilidade dentinária (HD) consiste em uma condição clínica caracterizada por dor localizada, curta e aguda, resultante de estímulos exógenos. Objetivo: Esse estudo objetivou realizar uma revisão da literatura sobre os aspectos relevantes vinculados à HD, como etiologia, diagnóstico, mecanismos biológicos, medidas preventivas e terapêuticas. Metodologia: Foi realizada a busca eletrônica de publicações nas bases de dados Scielo, PubMed, Periódicos Capes, Lilacs e Medline, utilizando os seguintes descritores: "dentin", "dentin sensitivy", "treatment". Os estudos foram publicados no período de 2010 a 2020. Resultados: Observou-se que a HD acomete cerca de 9-55% da população, principalmente indivíduos entre a terceira e quarta décadas de vida, apresentando maior prevalência no sexo feminino, afetando especialmente as regiões vestibulares dos caninos, pré-molares superiores e sequencialmente os incisivos e molares inferiores. O diagnóstico é determinado a partir de testes de sensibilidade, como o mecânico ou a desidratação. O tratamento dispõe de inúmeras propostas baseadas na obliteração dos túbulos dentinários como forma de impossibilitar a movimentação líquida intratubular ou restrição neural dos mecanorreceptores pulpares. Conclusão: Embora os aspectos clínicos sejam bem estabelecidos na literatura, a importância de um correto diagnóstico é essencial para um plano de tratamento adequado, por se tratar de uma condição de etiologia multifatorial...

Introduction: Dentin hypersensitivity (DH) consists of a clinical condition characterized by localized, hort and acute pain, resulting from exogenous stimulus. Objective: This study aimed to conduct a narrative literature review on the relevant aspects linked to DH, such as etiology, diagnosis, biological mechanisms, preventive and therapeutic approaches. Methodology: The electronic search for publications was carried out in the Scielo, PubMed, Capes, Lilacs and Medline databases, using the following descriptors: "dentin", "dentin sensitivy", "treatment". The studies were published in the period from 2010 to 2020. Results: It was observed that DH affects about 9-55% of the population, mainly belonging to the third and fourth decade of life, with higher prevalence in females, especially affecting the vestibular regions of the canines, upper premolars and sequentially the incisors and molars lower. The diagnosis is determined based on sensitivity tests, such as mechanical or dehydration. The treatment has numerous proposals based on the obliteration of the dentinal tubules as a way of preventing the intratubular liquid movement or neural restriction of the pulp mechanoreceptors. Conclusion: Although the clinical aspects are well established in the literature, the importance of a correct diagnosis is essential for an adequate treatment plan, as it is a multifactorial condition...

ABSTRACT

Os objetivos do estudo foram: 1. Avaliar, na dentina humana hipersensível, o efeito de enxaguatórios dessensibilizantes quanto à oclusão tubular dentinária; 2. Verificar a resistência da oclusão tubular promovida pelos tratamentos frente a desafios erosivos e abrasivos, realizados separadamente e em uma ciclagem erosiva-abrasiva; 3. Avaliar o efeito dos enxaguatórios no desgaste erosivo e abrasivo da dentina; 4. Avaliar a quantidade de fluoreto adsorvido no substrato dentinário após o tratamento com os enxaguatórios. Espécimes de 3 mm × 3 mm × 2 mm foram obtidos a partir da dentina radicular de 345 molares hígidos, e depois, polidos. Esses foram imersos em solução de EDTA 17% e, então, estratificadamente alocados em 10 grupos experimentais (n=10): Controle (água destilada); Enxaguatórios com ação dessensibilizante: Listerine Sensitive; Colgate Sensitive; Sensodyne Sensitive; Elmex Sensitive; enxaguatórios convencionais: Listerine; Colgate; Sensodyne; Elmex e ClinproTMXT Varnish (C+), como controle positivo. Na fase 1, espécimes foram tratados com os enxaguatórios e, depois, submetidos a um desafio erosivo ou a um desafio abrasivo. Na fase 2, os espécimes foram submetidos à um modelo de ciclagem de erosão-abrasão-remineralização (n=10) de 5 dias, onde o tratamento com os enxaguatórios foram aplicados 2 vezes ao dia. Após o EDTA, após os tratamentos (na fase 1 somente) e após os desafios ou ciclagem, os espécimes foram analisados por meio de Microscopia Eletrônica de Varredura Ambiental (MEV), e o programa de imagem Image J (NIH) foi utilizado para a contagem do número de túbulos dentinários abertos (TDA). A perda superficial (Surface Loss - SL) da dentina foi determinada com o uso de um perfilômetro óptico ao final dos desafios. Adicionalmente, a quantidade de fluoreto solúvel em KOH foi avaliada após uma aplicação dos enxaguatórios. Os dados foram analisados utilizando os testes Kruskal-Wallis, Dunn e Wilcoxon (=0,05). Na avaliação da oclusão tubular, após o tratamento, erosão e abrasão, C+ foi o único grupo que mostrou redução no número de TDA quando comparado ao Controle (p<0,05). Após a ciclagem, nenhum dos grupos exibiu uma redução significativa no número de TDA em relação ao Controle (p>0,05). Na análise de SL, para ambos os desafios isolados, não houve diferença significativa entre os grupos (p=0,372 e p=0,405). Para a ciclagem, o Listerine Sensitive apresentou significativamente o menor valor de SL e foi o único enxaguatório que diferiu significativamente do Controle (p<0,001). Nenhum enxáguatório foi capaz de promover oclusão significativa dos túbulos dentinários após o tratamento ou os desafios. C+ foi o único produto que efetivamente promoveu a oclusão tubular, mas esse efeito não suportou vários desafios erosivos e abrasivos. O único enxaguatório capaz de reduzir significativamente a SL dentinária comparada ao controle após desafios erosivos e abrasivos foi o Listerine Sensitive, que contém oxalato de potássio e fluoreto de sódio. Listerine e Sensodyne apresentaram a maior quantidade de fluoreto adsorvido.

ABSTRACT

Abstract Objective Our study aims to compare the efficacy and tooth sensitivity following in-office (35% hydrogen peroxide) or at-home (10% carbamide peroxide) bleaching treatments both preceded by 2% potassium nitrate (2%KF) desensitizing gel. Methodology 130 volunteers were randomly allocated to a) in-office bleaching and a placebo at-home protocol; or b) in-office placebo and at-home bleaching treatment. 2% KF was applied for 10 min before both treatments. Objective color evaluation was performed (spectrophotometer CIEL*a*b* system and CIEDE2000) to calculate the color change (ΔE00). Subjective evaluation was performed using the VITA classical shade guide followed by shade variation (ΔSGU) at the beginning and end of bleaching treatment and 2 weeks post-bleaching. Tooth sensitivity was daily recorded using a Likert scale varying from 1 (no sensitivity) to 5 (severe sensitivity). Analysis was carried out using non-parametric tests. Results Regarding the color change, at-home bleaching resulted in significant color improvement compared to in-office treatment for the parameters Δb* (p=0.003) and Δa* (p=0.014). Two weeks post-bleaching, the at-home treatment resulted in significant color improvement compared to in-office treatment for the parameters Δb* (p=0.037) and ΔE00 (p=0.033). No differences were observed in either ΔSGU parameters. Concerning sensitivity, patients treated with in-office bleaching reported more tooth sensitivity than the at-home group only on the first day after bleaching started, without significant differences in the other periods evaluated (p>0.05). Conclusions At-home and in-office bleaching, preceded by a desensitizing agent, were effective for vital teeth bleaching and 10% carbamide peroxide produced a higher whitening effect than 35% hydrogen peroxide in the short time evaluation. Tooth sensitivity rates were similar for the two techniques tested.

ABSTRACT

Introduction The non-carious cervical lesion (NCCL) is currently a common oral disease. Objective This observational and descriptive study aimed to assess risk factors associated with non-carious cervical lesions, cervical dentin hypersensitivity (CDH), gingival recession (GR) and the relationship between these conditions in students in the last years of undergraduate dentistry. Material and method One hundred eighty-five dentistry students from a private college in Ceará with an average of 22.7 ± 2.3 years participated by filling out a google docs form. Two calibrated examiners performed the exams to verify the presence of NCCL, CDH and RG. Result The presence of NCCL was 22.7%, GR was 48.1% and cervical dentin hypersensitivity 8.6%. The chi-square test with p < 0.05% verified a correlation between the presence of NCCL and the presence of GR and CDH. 25% of students had NCCL and 14% considered themselves stressed. There was no association between the variables bruxism and stress (p=0.529), bruxism and year of graduation course (p=0.716), as well as no association between stress and year of course (p = 0.397) was observed. There were no correlations between NCCL and bruxism, muscle symptoms, parafunctional habits and temporomandibular dysfunction. 10.8% of students who reported using legal and illegal drugs had NCCL. Conclusion The NCCL, GR and CDH were correlated in the group of students in the last two years of an undergraduate dentistry course in Ceará.

ABSTRACT

Objective: To evaluate fracture resistance and survival rate of IPS Empress CAD versus Polished Celtra Duo ceramic laminate veneers. Material and Methods:Thirty-six ceramic laminate veneers were fabricated for maxillary anterior teeth. The patients were divided into two groups according to the material Group 1(control group) fabricated from IPS Empress CAD laminate veneers and group 2 (intervention group) fabricated from Polished Celtra Duo laminate veneers. Standardized the same preparation with butt joint design and chamfer finish line located supra gingival were performed for all the teeth. The fabrication of the veneers was performed using Cad\Cam (Ceramill motion) machine, with software (Exocad). The veneers surfaces were treated and silanated according to the manufacture instruction of each ceramic and enamel surfaces were etched where total etch adhesive protocol was obeyed using BISCO. Follow up sessions were done every two months up to one year for each patient using dental probe and operator vision to evaluate the fracture, survival rate, marginal adaptation, sensitivity and caries. according to USPHS criteria (United States Public Health Service). This was performed by an experienced, blinded investigator. Results: Fracture resistance, marginal adaptation, retention, caries and sensitivity were evaluated according to the criteria of USPHS and we found there is no significant difference as both groups scaled zero score. Conclusion: Both IPS Empress Cad and Polished Celtra Duo laminate veneers revealed successful clinical performance in terms of fracture resistance, marginal adaptation, retention, and sensitivity after one year follow up period (AU)

ABSTRACT

OBJECTIVES@#This study was performed to evaluate the occlusion of monetite paste on dentine tubule and provide a new potential method for treating dentine hypersensitivity.@*METHODS@#Calcium oxide, strontium chloride, and polyethylene glycol phosphate were mixed in a certain proportion and ground in a planetary ball mill. The reaction was carried out by adjusting the pH to obtain monetite and hydroxyapatite paste. The morphological characteristics of the paste were observed through scanning electron microscope (SEM). The structure and composition were analyzed through X-ray diffraction (XRD) and Fourier transform infrared spectrometer (FTIR). The extracted third molar was selected to undergo demineralization to establish the @*RESULTS@#XRD and FTIR showed that the composition of the paste was mainly monetite, and the composition of hydroxyapatite paste was mainly composed of hydroxyapatite. SEM revealed that the size of the crystal particles of the synthesized paste was tens to hundreds of nanometers. Monetite and hydroxyapatite paste could produce a thicker mineralization layer on the dentin surface, and the mineralization of the dentin tubules of monetite was deeper than that of hydroxyapatite paste. The microhardness of the monetite paste group was significantly less than those of the hydroxyapatite paste groups (@*CONCLUSIONS@#Monetite paste could effectively block the exposed dentin tubules and be used for treating dentin hypersensitivity.

ABSTRACT

Acta Pediátrica Hondureña, Vol. 11 No.2/ Octubre 2020 a Marzo 2021 1186 El reflujo gastroesofágico (RGE) es el paso fisio- lógico del contenido gástrico hacia el esófago, presente en condiciones normales a cualquier edad y es uno de los problemas gastrointestinales más comunes en niños. El estado nutricional es adecuado y muchas veces por arriba de los per- centiles de peso y talla y es un niño "vomitador feliz". En cambio, la enfermedad por reflujo gas- troesofágico (ERGE) está asociada con síntomas molestos respiratorios, digestivos, trastornos durante el sueño, lesiones dentales las que en un gran número de casos pasan desapercibidas y son notadas hasta que han causado un daño signifi- cativo y pueden ir desde prurito, ardor de muco- sa, aumento de la sensibilidad dental y lingual, sabor amargo, erosiones hasta caries dental, estas cumplen un importante papel en la edad pediá- trica, sobre todo cuando el niño presenta trastor- nos en las funciones neurosensoriales, motoras, como daño neurológico secundario a encefalo- patía hipóxico isquémica, defectos del tubo neu- ral, atresia esofágica y enfermedades degene- rativas. Dentro de las complicaciones de ERGE cabe resaltar neumonía por broncoaspiración, otitis, faringoamigdalitis, crup y compromiso en el estado nutricional. La ERGE tiene gran impor- tancia médica y social debido al incremento en su incidencia y a los síntomas duraderos ya que reducen la calidad de vida. La habilidad de poder distinguir entre las mani- festaciones clínicas de RGE y ERGE en los dife- rentes grupos etarios nos permite identificar que pacientes deben ser extensamente evaluados y manejados con tratamiento conservador o si es- tos requieren ser derivados al odontólogo pedia- tra. Debido a que existe desconocimiento acerca de las lesiones dentales que se producen en la ERGE decidimos hacer la presente revisión ya que es muy importante que el personal de salud: estudiantes, médicos y odontólogos sean capaces de identificar, diagnosticar e implementar reco- mendaciones apropiadas, dar tratamiento espe- cífico tanto desde el punto de vista médico como dental dadas las repercusiones que esta conlleva y así derivar oportunamente...(AU)

ABSTRACT

RESUMEN: El principal motivo de consulta de los pacientes afectados con hipomineralización incisivo molar grado B 3 II, según la Academia Europea de Odontología Pediátrica (EAPO) es la estética y sensibilidad, provocando dolor a los cambios térmicos y a la hora de realizar el cepillado dental, esto puede conllevar a una rápida progresión de caries dental, por disminuir el cepillado. En el presente caso se describe la reconstrucción y sellado de fosas profundas de la pieza 46 afectada con hipomineralización incisivo molar, mejorando la calidad de vida relacionada a la salud bucal del paciente y eliminando la sensibilidad en una sola cita.


ABSTRACT: The main reason for consultation of patients affected by molar incisor hypomineralization level B 3 II (EAPO) is aesthetics and sensitivity, causing pain with thermal changes, when consuming cold drinks and when brushing the teeth. This can lead to a rapid progression of tooth decay, by decreasing the brushing. In the present case, the reconstruction and sealing of deep pits of the tooth 46 affected by molar incisor hypomineralization are described, improving the quality of life related to the patient's oral health and eliminating sensitivity in a single appointment.

ABSTRACT

As lesões cervicais não-cariosas (LCNCs) são problemas frequentes nos consultórios odontológicos. Possuem etiologia multifatorial e se caracterizam pela perda de esmalte na região cervical dos dentes, causando deficiência tanto funcional, quanto estética. Como consequência dessas lesões, existe a hipersensibilidade dentária, causada pela presença de fluídos no interior dos túbulos dentinários que atingem as terminações nervosas. Nesse sentido, o objetivo desta revisão de literatura foi realizar uma abordagem acerca das LCNCs, evidenciando os fatores etiológicos, suas consequências e a importância do correto diagnóstico e remoção do agente causador para a realização dos diferentes métodos de tratamentos. Diante dessa realidade, o tratamento varia de acordo com o diagnóstico do aparecimento dessas lesões, sejam elas causadas por fatores intrínsecos ou extrínsecos ou a união de ambos. Sendo de fundamental importância o controle dos mesmos para o sucesso do tratamento e uma maior longevidade das estruturas dentárias.


Non-Carious Cervical Injuries (NCCIs) are frequent problems in dental offices. They have a multifactorial etiology and are characterized by the loss of enamel in the cervical region of the teeth, causing both functional and aesthetic deficiencies. Because of these injuries, there is tooth hypersensitivity, caused by the presence of fluids inside the dentinal tubules that reach nerve endings. In this sense, the objective of this literature review was to conduct an approach about NCCI, highlighting the etiological factors, their consequences and the importance of the correct diagnosis and removal of the causative agent for the realization of the different treatment methods. In view of this reality, treatment varies according to the diagnosis of the appearance of these lesions, whether they are caused by intrinsic or extrinsic factors or the union of both. Being of fundamental importance the control of the same for the success of the treatment and a greater longevity of the dental structures.

ABSTRACT

Abstract Objective This study evaluated the clinical effect of violet LED light on in-office bleaching used alone or combined with 37% carbamide peroxide (CP) or 35% hydrogen peroxide (HP). Methodology A total of 100 patients were divided into five groups (n=20): LED, LED/CP, CP, LED/HP and HP. Colorimetric evaluation was performed using a spectrophotometer (ΔE, ΔL, Δa, Δb) and a visual shade guide (ΔSGU). Calcium (Ca)/phosphorous (P) ratio was quantified in the enamel microbiopsies. Measurements were performed at baseline (T 0 ), after bleaching (T B ) and in the 14-day follow-up (T 14 ). At each bleaching session, a visual scale determined the absolute risk (AR) and intensity of tooth sensitivity (TS). Data were evaluated by one-way (ΔE, Δa, ΔL, Δb), two-way repeated measures ANOVA (Ca/P ratio), and Tukey post-hoc tests. ΔSGU and TS were evaluated by Kruskal-Wallis and Mann-Whitney, and AR by Chi-Squared tests (a=5%). Results LED produced the lowest ΔE (p<0.05), but LED/HP promoted greater ΔE, ΔSGU and Δb (T 14 ) than HP (p<0.05). No differences were observed in ΔE and ΔSGU for LED/CP and HP groups (p>0.05). ΔL and Δa were not influenced by LED activation. After bleaching, LED/CP exhibited greater Δb than CP (p>0.05), but no differences were found between these groups at T 14 (p>0.05). LED treatment promoted the lowest risk of TS (16%), while HP promoted the highest (94.4%) (p<0.05). No statistical differences of risk of TS were found for CP (44%), LED/CP (61%) and LED/HP (88%) groups (p>0.05). No differences were found in enamel Ca/P ratio among treatments, regardless of evaluation times. Conclusions Violet LED alone produced the lowest bleaching effect, but enhanced HP bleaching results. Patients treated with LED/CP reached the same efficacy of HP, with reduced risk and intensity of tooth sensitivity and none of the bleaching protocols adversely affected enamel mineral content.

ABSTRACT

Abstract Objective To clinically assess the effect of desensitizing gels and dentifrices on the reduction in pain sensitivity and color variation during tooth bleaching. Methodology A total of 108 volunteers were randomly separated into the following groups of n=12: GT/S-glycerine and thickener/sucralose; NF/S-potassium nitrate and sodium fluoride/sucralose; NA/S-potassium nitrate and arginine/sucralose; GT/AC-glycerine and thickener/arginine and calcium carbonate; NF/AC-potassium nitrate and sodium fluoride/arginine and calcium carbonate; NA/AC-potassium nitrate and arginine/arginine and calcium carbonate; GT/PN-glycerine and thickener/potassium nitrate; NF/PN-potassium nitrate and sodium fluoride/potassium nitrate; and NA/PN-potassium nitrate and arginine/potassium nitrate. Sensitivity was assessed with the numerical analogue scale, and color variation (ΔE) was measured with a spectrophotometer. The sensitivity values obtained were subjected to a multivariate analysis of variance (MANOVA) and color variation values were subjected to a randomized analysis of variance (p<0.05). Results The NF/AC, NA/AC, NF/PN, and NA/PN groups presented lower sensitivity values and reduced sensitivity compared to those of the other groups throughout the clinical sessions. None of the groups showed sensitivity at the 24-week assessment. Statistically, no significant difference were observed in the color values among the groups four weeks after the beginning of bleaching (p=0.074). Additionally, the color assessment of all groups was statistically similar four weeks (p=0.084) and 24 weeks (p=0.118) after the beginning. Conclusion Our results indicate that adding NF/S, NA/S, NF/AC, and NA/AC desensitizers to tooth bleaching protocols reduces pain sensitivity without affecting its effectiveness.

ABSTRACT

Abstract Objectives This randomized, split-mouth, single-blinded trial assessed whether the use of reservoirs in at-home bleaching trays is equivalent to non-reservoir trays. Our choice of an equivalence trial was based on the expectation that a non-reservoir tray is sufficient to produce a color change. Secondary outcomes such as tooth sensitivity (TS) and gingival irritation (GI) were also assessed. Methodology Forty-six patients were selected with canines shade A2 or darker. In half of the patient's arch, bleaching trays were made with reservoirs and the other half, without reservoirs. At-home bleaching was performed with carbamide peroxide (CP) 10% (3 h daily; 21 days). Color change was evaluated with a digital spectrophotometer (ΔE, ΔE00, and Whiteness Index) and shade guide units (ΔSGU) at baseline, during and one-month post-bleaching. TS and GI were assessed with a numeric scale (NRS) and a visual analog scale (VAS). Results After one month, the equivalence of reservoir and non-reservoir groups were observed in all color instruments (p>0.05). Fifteen and sixteen patients presented pain (absolute risk: 33% and 35%, 95%, confidence interval (CI) 21-46% and 23-49%) in the reservoir and non-reservoir side, respectively. The odds ratio for pain was 0.8 (95%CI 0.2-3.0) and the p-value was non-significant (p=1.0). TS intensity was similar between both groups in any of the pain scales (p>0.05). No difference in the GI was observed (p>0.05). Conclusions The protocol with reservoirs is equivalent in color change to the non-reservoir, although no superiority of the latter was observed in terms of reduced TS and GI with at-home 10% carbamide peroxide bleaching. Clinical Relevance The presence of reservoirs in a bleaching tray did not improve color change or affect tooth sensitivity and gingival irritation.

ABSTRACT

Abstract Gingival conditions and tooth sensitivity of young patients with amelogenesis imperfecta lack in depth studies. This case-control study aimed to compare (1) the gingival inflammation, the presence of enamel defects, and tooth sensitivity in young patients with and without amelogenesis imperfecta and (2) to investigate if any difference exists between subtypes of amelogenesis imperfecta. Methodology We compared forty-two participants with amelogenesis imperfecta with forty-two controls matched for age, gender, and the number of examined sites. Based on interview, clinical examination, and intraoral photography, we collected data on periodontal conditions, enamel defects and the presence of tooth sensitivity. Comparison tests were performed to investigate if any difference existed between cases and controls; and among cases, between the different subtypes of amelogenesis imperfecta. We performed a post-hoc analysis for any significant difference observed. Results We observed more gingival inflammation, enamel defects and tooth sensitivity among cases (all p<0.05). Participants with hypocalcified amelogenesis imperfecta had more gingival inflammation, enamel defects, and tooth sensitivity than patients with the hypoplastic and hypomature subtypes (all p<0.05). After adjustment for dental plaque, gingival inflammation was associated with the presence of amelogenesis imperfecta (OR (95%CI) = 1.14 (1.05; 1.24). p<0.01). Conclusion Gingival inflammation, enamel defect and tooth sensitivity are more frequently observed among young patients with amelogenesis imperfecta, and more specifically among children with the hypocalcified subtype.

ABSTRACT

Aim: Evaluate the effect of adhesives systems combined with desensitizer agents on the microtensile bond strength (µTBS) of a composite resin to dentin. Methods: Cervical dentin of thirty-two human molars were used to simulate hypersensitivity areas. The teeth were divided into four groups (n=8), according to the type of adhesive system and desensitizer agents. No desensitizer was used in the control (Clearfil SE Bond ­ CS). Two experimental groups were pretreated with either MS Coat Bond (MS) or Biofluorid 12 (BF) immediately prior to bonding with CS. The last group corresponded to Gluma Comfort Bond + Desensitizer (GC) application. After dentin treatments, a composite block was built-up on dentin surface and after 24 hours teeth were serially sectioned to obtain bonded bean specimens. Beams were stored in water for 24 hours or one year. Subsequently, the specimens were submitted to the µTBS test. Data were analyzed by two-way mixed ANOVA and Bonferroni's test (α = 0.05). Results: At 24 hours, there was no significant difference in µTBS among groups. However, at one year, dentin treated with MS or BF demonstrated significantly lower µTBS of CS to dentin compared to control and GC, which kept their µTBS stable. Conclusion: The effect of MS and BF desensitizer agents on the µTBS of CS to dentin did not reduce the µTBS at 24 hours, but it decreases significantly after one year

ABSTRACT

Objective: To evaluate the post operative sensitivity in posterior restorations with different resin composites and adhesive systems as well as the influence of the depth and extent of the dental cavity. Material and Methods: A double-blind clinical trial was carried out with 80 class I restorations of 16 patients. The participants were divided into 4 groups according to the adhesive system + composite: F + P (Filtek P90™ + P90™); R + S (Rok™ + Stae™); P + A (P60™ + Adper SE PLUS™); E + X (Evolux™ + XPBond™ Adhesive). After 7, 15 and 30 days, the presence of postoperative sensitivity was evaluated and classified according to type and intensity. The data were submitted to Pearson'schi-square test, Fisher's exact teste, Student'st-test and ANOVA. A significance level of 5%was used for all tests. Results: The presence of post operative sensitivity was approximately 6% of the total sample. The sensitivity decreased with the evaluation time, with the smallest reduction occurring from the 7-day evaluation compared to the other evaluations. Conclusion: There was found no evidence of influence of the resin composite and adhesive type, depth and extension of the cavities for the presence of postoperative sensitivity. (AU)

ABSTRACT

Abstract The aim of the present study was to compare the sensitivity and specificity of pain scales used to assess dentin hypersensitivity (DH). The preferred scale, and toothbrushing habits of participants were also investigated. This cross-sectional study was conducted with students and employees of a Brazilian Federal University who presented DH. The participants answered a questionnaire about their toothbrushing and drinking habits. Hypersensitive and non-sensitive teeth were submitted to tactile and ice stick stimuli. Then, the subjects marked their pain level in the visual analogue (VAS), numeric scale (NS), faces pain scale (FPS) and verbal evaluation scale (VES). DH was also assessed by Schiff scale (SS). The data were analyzed by Wilcoxon and Chi-Square tests, as well as by ROC curve. The mean age of the sample (56 women, 16 men) was 27.8 years. The most prevalent acidic beverage was coffee (36.0%) and the most preferred scale was the NS (47.2%). The pain level was statistically higher in teeth with DH compared to teeth without DH (p < 0.05). The accuracy ranged from 0.729 (SS) to 0.750 (NS). The highest sensitivity value was 81.9% for NS. The SS presented the highest specificity (91%). The visual analog, numerical, verbal evaluation, faces pain, and Schiff scales were accurate for DH diagnosis. The Schiff scale was the preferred scale for DH assessment.
