The purposes of this study were to evaluate in vitro the influence of different frequencies of Er:YAG laser on the human dentin caries removal capacity. Thirty fragments obtained from third molars were randomly assigned into three groups (n = 10) according to the laser frequency used: 4, 6, and 10 Hz. The caries lesion (+/-1 mm deep) was induced before the irradiation by S. mutans cultures for 6 weeks. The specimens of all groups were irradiated with 200 mJ of energy in noncontact and focused mode under constant refrigeration (water flow: 2.5 mL/min). Quantitative analysis of the caries removal was performed by DIAGNOdent (TM) and the Axion Vision (TM) software. Qualitative analysis was performed by Scanning electron microscope (SEM) and light microscope (LM). Data were analyzed by ANOVA and Fishers` tests. The DIAGNOdent (TM) revealed that the caries removal was similar with 4 and 6 Hz and was superior with 10 Hz (P < 0.05). The analysis with Axion Vision (TM) software revealed that the caries removal was similar with 6 and 10 Hz and the 4 Hz group promoted the lowest caries removal. Through SEM morphologic analysis, some specimens irradiated with 4 Hz presented, under the demineralized dentin, a disorganized collagenous matrix. The LM images revealed that all frequencies used promoted irregular caries removal...

This study evaluated the influence of the dental substrates obtained after the use of different caries removal techniques on bonding of a self-etching system. Forty, extracted, carious, human molars were ground to expose flat surfaces containing caries-infected dentine surrounded by sound dentine. The caries lesions of the specimens were removed or not (control-G1) either by round steel burs and water-cooled, low speed, handpiece (G2), or by irradiation with an erbium, chromium:yttrium scandium gallium garnet (Er,Cr:YSGG) laser (2W, 20 Hz, 35.38 J/cm(2), fiber G4 handpiece with 0.2826 mm(2), non-contact mode at a 2 mm distance, 70% air/20% water-G3) or using a chemo-mechanical method (Carisolv-G4). Caries-infected, caries-affected and sound dentines were submitted to a bonding system followed by construction of a resin-based composite crown. Hour-glass shaped samples were obtained and submitted to a micro-tensile bond test. The bond strength data were compared by analysis of variance (ANOVA), complemented by Tukey`s test (P <= 0.05). The samples of sound dentine presented higher bond strengths than did samples of caries-affected dentine, except for the groups treated with the Er,Cr:YSGG laser. The highest bond strengths were observed with the sound dentine treated with burs and Carisolv. The bond strengths to caries-affected dentine were similar in all groups. Additionally...

O objetivo do trabalho foi avaliar as alterações comportamentais e fisiológicas durante a remoção de tecido cariado através dos métodos mecânico e químico-mecânico (CARISOLV TM ), sob anestesia local com lidocaína a 2% sem vasoconstritor, em crianças com Síndrome de Down. O estudo foi realizado em 20 crianças ASA I, sendo 10 crianças com Síndrome de Down (grupo experimental) e 10 crianças “normais” (grupo controle), de 5 a 12 anos de idade. Foram realizadas avaliações comportamentais, através do índice de Venham modificado e mensurações automáticas (Criticaire System® - Scholar II) dos seguintes parâmetros fisiológicos: freqüência cardíaca, pressão arterial sistólica, pressão arterial diastólica e saturação de oxigênio, e comparados aos valores basais. A avaliação dos parâmetros comportamentais e fisiológicos ocorreram em 5 fases: (1) 5 minutos antes da anestesia local; (2) durante a anestesia local; (3) durante a remoção do tecido cariado; (4) imediatamente após a restauração e (5) 5 minutos após o término do procedimento. A fase de remoção do tecido cariado apresentou a maior alteração comportamental e fisiológica para todas as variáveis analisadas, exceto para a saturação de oxigênio. Em relação à alteração comportamental não foram observadas diferenças estatisticamente significantes (significantes a 5 %)entre os tipos de tratamento para a remoção do tecido cariado em ambos os grupos. Em relação à freqüência cardíaca...

Este trabalho in vitro teve objetivo de avaliar a superfície dentinária remanescente após remoção de tecido dentinário cariado, com instrumento cortante rotatório em baixa rotação e dois métodos químico-mecânicos (Papacárie® e Carisolv®) através da fluorescência laser (DIAGNOdent), microdureza e microscopia eletrônica de varredura. Na primeira fase do estudo, trinta incisivos decíduos com lesão de cárie em uma das faces proximais provenientes do Banco de Dentes Humanos da FOUSP foram avaliados antes e após a remoção do tecido cariado, pela fluorescência laser, sendo posteriormente preparados avaliação da microdureza . O teste de microdureza foi realizado em diferentes distâncias abaixo da dentina tratada após remoção do tecido cariado (50, 100, 150, 200, 300, 400 e 500µm) e do lado hígido (100, 150, 200, 300, 400, 500, 1000 e 1500 µm). Posteriormente, mais 30 dentes decíduos cariados foram divididos em três grupos de acordo com os diferentes tipos de tratamento para análise em MEV, sendo 15 dentes para análise do substrato e 15 dentes para observação de réplicas. Para obtenção destas, os dentes foram restaurados com o adesivo Single Bond (3M) e resina Filtek Z100 (3M) para avaliação de tags (15). Concluiu-se que houve diferença estatisticamente significante nos valores de fluorescência laser da dentina cariada e da dentina após a remoção do tecido cariado...

Com o objetivo de testar a qualidade das restaurações realizadas após a remoção de cárie de raiz com laser de alta potência, realizamos esse trabalho. Lesões de cárie radicular foram induzidas em fragmentos dentais humanos (n=154) através de contaminação com o S. mutans. Obtidas as lesões, essas foram removidas com instrumento cortante rotatório (ICR) em baixa rotação (grupo controle) ou com o laser de Er,Cr:YSGG, (?=2,78 µm, taxa de repetição= 20 Hz, duração de pulso na ordem de 140 a 150 µs, energia por pulso de 0 a 300 mJ) em 13 potências diferentes entre 1 e 4 W, em intervalos de 0,25 W entre cada grupo (n=11 por grupo). Para a remoção de cárie, foi utilizada a peça de mão 2415 e a fibra de safira modelo ?G? (Ø= 600 µm) posicionada a 1 mm das amostras (modo não contato). Após a remoção das lesões de cárie e mensuração do tempo necessário para este passo operatório, uma amostra de cada grupo foi preparada para microscopia eletrônica de varredura (MEV). Em seguida, as demais foram condicionadas com Clearfil SE Bond, restauradas com resina composta de baixa viscosidade e submetidas à termociclagem (1.000 ciclos de 5°C e 55°C) e então imersas em solução de azul de metileno a 2 % para teste de microinfiltração. Depois desta etapa...

O objetivo deste estudo foi avaliar a alteração de temperatura durante preparo cavitário em dentina cariada e hígida e a eficiência na remoção de tecido cariado com Er:YAG. Foram utilizados 30 terceiros molares humanos hígidos, doados pelo Banco de Dentes da FORP-USP, os quais tiveram suas raízes removidas e as coroas seccionadas, obtendo-se 60 fragmentos de 2,5mm de espessura. Os espécimes foram divididos em 2 grupos (n=30): dentina cariada e dentina hígida (controle) e em 3 subgrupos (n=10), de acordo com as freqüências de laser aplicadas (4, 6 e 10Hz). Foi empregada energia constante de 200mJ no modo não-contato, focado e sob refrigeração. A indução das lesões artificiais de cárie foi realizada pelo modelo bacteriano, no qual foram utilizadas cepas de Streptococcus mutans. O registro da temperatura foi realizado antes do inicio da irradiação, após 10 segundos e ao final do preparo. Após este procedimento, os fragmentos foram analisados por DIAGNOdent® e microscopia óptica de luz, utilizando-se o software Axio Vision 4.3 LE, para quantificar a remoção de dentina cariada. Para a análise morfológica, 5 espécimes de cada grupo foram aleatoriamente selecionados e preparados para microscopia eletrônica de varredura. Os dados foram submetidos à Análise de Variância α=5% e...

Este é um estudo de acompanhamento de cinco anos de um ensaio clínico randomizado controlado multicêntrico, que teve como objetivo avaliar a efetividade de uma abordagem alternativa no tratamento de lesões de cárie profundas em comparação ao tratamento expectante (TE). O tratamento alternativo consistiu na remoção parcial de tecido cariado (RPTC) e restauração em sessão única. A amostra incluiu molares com lesões chegando até metade interna de dentina e sem lesão periapical ao exame radiográfico, resposta positiva ao teste frio, negativa ao teste de percussão e ausência de dor espontânea. Estes foram randomicamente atribuídos ao grupo teste (RPTC) ou controle (TE). Os pacientes do grupo teste receberam remoção incompleta de tecido cariado e restauração em amálgama ou resina composta em uma sessão. Os pacientes do grupo controle, após remoção incompleta do tecido cariado, receberam capeamento pulpar indireto com cimento de hidróxido de cálcio e restauração temporária com cimento de óxido de zinco e eugenol modificado na primeira sessão. Após mediana de tempo de 90 dias, a cavidade era reaberta para remoção da dentina cariada remanescente e restauração em resina composta ou amálgama. O desfecho avaliado no estudo foi a vitalidade pulpar...

O conhecimento atual sobre a etiopatogenia da doença cárie permite tratamentos mais conservadores. A técnica da remoção parcial de tecido cariado (RPTC) é um exemplo dessa nova abordagem, pois permite uma maior preservação da estrutura dentária e evita exposições pulpares. No entanto, pouco se conhece sobre as restaurações de resina composta após esse tratamento. O objetivo deste estudo foi avaliar o desempenho das restaurações de resina composta após a técnica de RPTC em comparação à RTTC após 36 meses de acompanhamento. O estudo envolveu 48 crianças de 3 a 8 anos, portadoras de lesões cariosas agudas profundas na superfície oclusal ou ocluso-proximal(is). No total, 120 dentes (65 RPTC e 55 RTTC) foram analisados. A randomização foi realizada através de sorteio. Um único avaliador treinado e calibrado avaliou a presença da perda total ou parcial das restaurações. As variáveis explicativas foram relacionadas ao desfecho através dos testes estatísticos de Regressão de Cox uni e multivariados (α=5%). A taxa total de sobrevida das restaurações foi de 69,5% após 36 meses. Para os grupos da RTTC e RPTC o sucesso foi de 81% e 57%, respectivamente (p=0,004). Observou-se uma menor taxa de sobrevida de restaurações em dentes com cavidades ocluso proximais (58%) comparadas às oclusais (87%)...

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Processo FAPESP: 04/00677-1; The aims of this study were to evaluate clinically and microbiologically the effects of two resin-modified glass-ionomer cements (RMGICs) used as liners after incomplete dentine caries removal and to identify Streptococcus mutans and Streptococcus sobrinus strains isolated from dentine samples, before and after indirect pulp treatment. Twenty-seven primary molars with deep carious lesions, but without signs and symptoms of irreversible pulpitis, were submitted to indirect pulp treatment. Treatment consisted of incomplete excavation of the carious dentine, application of one of the RMGICs (Vitrebond or Fuji Lining LC) or calcium hydroxide cement (Dycal), and sealing for 3 months. Clinical evaluation (consistency, color, and wetness of dentine) and carious dentine collects were performed before temporary sealing and after the experimental period. Microbiological samples were cultivated in specific media for subsequent counting of mutans streptococci (MS) and lactobacilli (LB). MS colonies were selected for identification of S. mutans and S. sobrinus by polymerase chain reaction. After 3 months...

Aim: Despite the antibacterial properties of dental materials, the survival of residual bacteria under restorations has been demonstrated after incomplete caries removal. The aim of this study was to evaluate the genetic polymorphism of Streptococcus mutans strains isolated from deep dentinal lesions before and three months after incomplete caries removal. Methods: Samples of carious dentin were collected from 33 primary and/or permanent molars before and after indirect pulp treatment and processed for microbiological isolation of mutans streptococci (MS). After three months of the dental treatment, positive cultures for MS were detected in only ten of these teeth. DNA of MS isolates were obtained and subjected to polymerase chain reaction (PCR) for identification of S mutans. The arbitrary primed-PCR method (primer OPA-13) was used to detect the genetic polymorphism of S. mutans strains. Results: Identical or highly related S. mutans genotypes were observed in each tooth, regardless of the collect. Considering each tooth separately, a maximum of nine genotypic patterns were found in each tooth from all the collects. In addition, at least one genotypic pattern was repeated in the three collects. Genetic diversity was observed among the S. mutans isolates...

The methods of caries removal have been the subject of many studies over the last years. At present, methods involving the least tissue invasion have been outstanding in the field of surgical-restorative treatment. In this context, the Carisolv™ system has appeared as a less traumatic and less invasive approach, particularly in pedodontics. Thus, the objective of the present study was to carry out a comparative analysis of the dentinal structure of primary molars before and after the removal of carious tissue by mechanical (low speed drills and conventional dentinal curettes) and chemomechanical (Carisolv™ kit) procedures based on quantitative culture for cariogenic bacteria to determine the number of bacteria present in the carious dentine after both treatments. Sixty primary molars from children ranging in age from 4 to 8 years, with active occlusal caries in dentine, were divided into two groups (A and B) of 30 teeth each, with group A having been treated by the chemomechanical technique and group B by the mechanical technique. Dentin samples were placed in glass vials containing 1 mL thioglycolate broth and submitted to culture to determine the number of S. mutans and Lactobacillus per mg of decayed dentine. The results did not reveal significant differences between the two methods of caries removal; however...

Objectives: Compare the effectiveness of PapacarieTM gel for the chemo-mechanical removal of carious lesions on primary teeth to conventional caries removal with a low-speed bur with regard to execution time, clinical aspects and radiographic findings. Material and Methods: A randomized controlled clinical trial with a split-mouth design was carried out. The sample was composed of 20 children aged four to seven years, in whom 40 deciduous teeth were randomly divided into two groups: chemo-mechanical caries removal with PapacarieTM and removal of carious dentin with a low-speed bur. Each child underwent both procedures and served as his/her own control. Restorations were performed with glass ionomer cement. The time required to perform the procedure was also analyzed. The patients underwent longitudinal clinical and radiographic follow-up of the restorations. Results: No statistically significant difference between groups was found regarding the time required to perform the procedures and the radiographic follow up. Statistically significant differences between groups were found in the clinical evaluation at 6 and 18 months after treatment. Conclusion: PapacarieTM is as effective as the traditional method for the removal of carious dentin on deciduous teeth...

The aim of this study was to compare the efficacy of chemochemical methods (Carisolv™ and Papacárie®) versus the manual method (excavators) in reducing the cariogenic microbiota in dentine caries of primary teeth. Forty-six healthy children (5 to 9 years old) having at least one primary tooth with a cavitated dentine carious lesion were included in the study. The teeth presented no clinical or radiographic signs of pulpal involvement. The sample of 74 teeth was randomly divided into three different groups: Papacárie® (n = 25), Carisolv™ (n = 27) and Manual (n = 22). Samples of carious and sound dentine were collected with sterile excavators before and after caries removal in the three groups. The dentine samples were transferred to glass tubes containing a 1mL thioglycollate medium used as a carrier and enriched for microbiological detection of mutans streptococci and Lactobacillus spp, after incubation for 6h at room temperature. The minimum detection value for colony forming units (CFU) was 3.3 x 102 CFU/ml, and the results were converted into scores from 0 to 4. A significant difference was observed in relation to the microbiological scores before and after caries removal for all methods (Wilcoxon test; p < 0.001). The use of chemomechanical methods for caries removal did not improve the reduction of cariogenic microorganisms in dentine caries lesions...

This study investigated the influence of a papain-based gel(Papac??rie) for chemo-mechanical caries removal on bond strength to dentin. Human molars were assigned to the following groups: Group 1: sound teeth were flattened to expose dentin; Group 2: after flattening of surfaces, the papain-based gel was applied on the sound dentin; Group 3: overlying enamel from carious teeth was removed and mechanical excavation of dentin was conducted; Group 4: chemo-mechanical excavation of carious dentin was conducted using the papain-based gel. The Prime&Bond NT or Clearfil SE Bond adhesive systems were used for restorative procedures. A microtensile bond strength test was performed,and the modes of failure were determined under SEM. The data were submitted to two-way ANOVA and Tukey???s test (p ??? 0.05). No significant differences were observed between the sound dentin groups. For both excavation methods, Clearfil presented a significantly higher bond strength than Prime&Bond NT.Also, for Clearfil, the mechanically excavated samples disclosed a significantly higher bond strength than the chemo-mechanically ones. For Prime&Bond NT, no significant differences were detected between the excavation methods. Predominance of mixed failures for the sound substrate and of adhesive failures for the carious dentin one was detected. The bond strength to carious dentin of the self-etching system was negatively affected by chemo-mechanical excavation using the papain-based gel.

This paper assesses clinical/radiographic changes after incomplete carious dentine removal and tooth sealing. 32 teeth with deep caries lesions were studied. The treatment consisted of incomplete excavation, application of Ca (OH)2 layer, sealing for a 6-7 month period, and then restored. Standardized bitewing radiographs were taken after the temporary sealing, and at 6-7, 14-18, and 36-45 month intervals. The digitized images were analyzed: qualitatively in regard to the radiolucent zone (RZ) depth and tertiary dentine (6-7 and 36-45 months) and quantitatively in regard toradiographic density by image subtraction (6-7, 14-18, and 36-45 months). The subtractions were performed in the RZ beneath the restoration and in two control areas (CA). During the 6-7 month period, there was 1 pulp necroses and 1 pulpexposure, and at the 36-45 month interval, 3 fractures and 3 withdrawals. Nine cases showed a decrease in RZ depth in the 6-7 month period and 3 more cases, at the 36- 45 month period. Four cases displayed tertiary dentine.

This investigation aims to discuss the methodologies applied in clinical trials published about CarisolvTM, in order to assess the best scientific evidence concerning chemo-mechanical caries removal. Papers concerning the use of CarisolvTM were sought using a search strategy. The titles and abstracts of all the reports identified through the search were analyzed by a single reviewer. The inclusion criterion involved: clinical trials having CarisolvTM in one of the study groups. Then, those that fulfilled the inclusion criterion underwent methodology assessment and data extraction. Only 12 papers met the inclusion criterion. It was observed that none of these studies complied with all the evaluated research methodological principles required in order to have power of evidence generation. CarisolvTM proved to be effective in caries removal. Appointment mean time was greater, but the perceived time was shorter than that using conventional techniques due to patients' perception of more comfort and a reduction of anesthesia needs. There were no adverse effect in long-term assessments. In studies with microbiological evaluation of the remaining dentine, it was observed that both the conventional and chemo-mechanical methods produced statistically significant reduction on counts of viable microorganisms.

Os métodos de remoção de cárie têm sido objeto de muitos estudos nos últimos anos. Atualmente, aqueles que determinam mínima invasão tecidual têm se sobressaído no campo do tratamento cirúrgico-restaurador. Neste contexto, surgiu o sistema Carisolv™ como uma abordagem menos traumática, com destaque na odontopediatria e menos invasiva. Desta forma, este estudo teve como objetivo analisar comparativamente a estrutura dentinária de molares decíduos antes e após a remoção do tecido cariado pelos métodos mecânico (brocas de baixa rotação e curetas dentinárias convencionais) e químico-mecânico (Kit Carisolv™), através de exame microbiológico quantitativo, verificando-se o número de bactérias/mg presentes na dentina cariada após cada tratamento. Foram utilizados 60 molares decíduos de crianças na faixa etária de 4 a 8 anos de idade que apresentavam cárie oclusal ativa em dentina, os quais foram divididos em dois grupos (A e B) de 30 dentes cada, onde o grupo A foi tratado com a técnica químico-mecânica e o grupo B foi tratado com a técnica mecânica. As amostras de dentina foram coletadas e depositadas em frascos de vidro contendo 1mL de caldo Tioglicolato e pérolas de vidro. Em seguida, foram imediatamente encaminhadas para análise microbiológica para que fossem determinadas as concentrações de S. mutans e Lactobacillus por mg de dentina cariada. Os resultados não revelaram diferenças significantes na comparação dos dois métodos de remoção de cárie; contudo...

The use of minimally invasive procedures and attention to patient comfort are of great importance, especially for dental treatment in young children. This has led to the development of chemomechanical methods for caries removal. Aim: To evaluate and compare the antimicrobial efficacy, efficacy in terms of time consumption and pain perception of chemomechanical caries removal agent Papacarie® and conventional method of caries removal. Methods: Subjects for this study were chosen from children admitted to dental clinic for restorative procedures. Forty children (age 4-8 years) with early childhood caries were included in this study. Two primary teeth with comparable degrees of carious destruction were chosen in each child for caries removal with either Papacarie® or rotary instruments. The time taken for caries removal was measured using stopwatch. Pain response during caries removal was evaluated using the Wong Baker Face Pain Scale. Dentin samples of both groups were taken prior to, and after caries removal for microbiological analysis. Results The time taken for caries removal in chemomechanical caries removal method was three times longer than the conventional method. Pain score during chemomechanical method of caries removal was 1.525 as compared with 6.65 when conventional method was used. The antimicrobial efficacy of chemomechanical caries removal was significantly similar to conventional method. Conclusions: Papacarie® can be an effective clinical alternative treatment for the removal of occlusal dentinal caries in cavitated primary molars.

Aim: This study evaluated the influence of different chemomechanical caries removal techniques on the bond strength of an adhesive system to caries-affected and healthy dentin. Methods: Thirty healthy teeth were randomly divided into three groups: Group 1 (control): no caries removal technique was applied; Group 2: chemomechanical technique using Carisolv®; and Group 3: chemomechanical technique using Papacárie®. Twenty caries-affected teeth were divided into two groups: Group 4: chemomechanical technique using Carisolv; and Group 5: chemomechanical technique using Papacárie. The teeth received the application of an etch-andrinse adhesive system, were restored with composite resin, and then sectioned to obtain 4 hourglassshaped slabs from each specimen, which were subjected to a microtensile bond strength test. Data were analyzed statistically by ANOVA and Tukey’s test (a=0.05). Results: G1 (13.387 ± 6.1074), G2 (18.123 ± 3.2611) and G3 (12.781 ± 4.5652) presented statistically significant higher mean bond strength values than the other groups (p<0.05), but did not differ significantly from each other (p>0.05). G4 (6.228 ± 5.3435) and G5 (6.482 ± 3.2076) presented the lowest mean bond strength values and were statistically similar to each other (p>0.05). Conclusions: Neither of the chemomechanical caries removal methods interfered in the resin-dentin bond strength. However...
