ABSTRACT

OBJECTIVE@#To compare the clinical effects of pulpotomy with two kinds of calcium silicate materials, and to evaluate the formation of dentin bridge and pulp calcification after pulpotomy of adult permanent teeth.@*METHODS@#Patients who visited the General Department of Peking University School and Hospital of Stomatology from November 2017 to September 2019 and planned for pulpotomy on permanent premolars and molars with carious exposed pulp were selected. They were randomly divided into two groups. Bioceramic putty material iRoot BP (iRoot group, n=22) and mineral trioxide aggregate MTA (MTA group, n=21) were used as pulp capping agents, respectively. The patients were recalled after one year and two years. The clinical efficacy, dentin bridge index (DBI) and pulp calcification index (PCI) were recorded. Blinding method was used for the patients and evaluators.@*RESULTS@#There was no significant difference in gender, mean age, dentition and tooth position between the two groups (P>0.05). Seven cases were lost during the first year (4 cases in iRoot group and 3 cases in MTA group). In the iRoot group, 1 case had transient sensitivity at the time of 1-year follow-up. The cure rate of the two groups was 100% at the time of 2-year follow-up. The proportion of dentin bridge formation was 38.9% one year after operation, 55.6% two years after operation. The proportion of partial or even complete disappearance of root canal image was 5.6% before operation, 38.9% and 55.6% one and two years after operation, respectively. The difference was statistically significant by rank sum test (P < 0.05). There was no significant difference in dentin bridge formation and pulp calcification between the two groups (P < 0.05). DBI and PCI after operation was as the same as those before operation (44.4% cases of DBI and 25% cases of PCI) or gradually increased (55.6% cases of DBI and 75% cases of PCI). Spearman's nonparametric correlation analysis showed that age was positively correlated with preoperative pulp calcification index (PCI0, P < 0.05), but not with the dentin bridge index (DBI1, DBI2), pulp calcification index (PCI1, PCI2) and the degree of change (DBI2 vs. DBI1, PCI1 vs. PCI0, PCI2 vs. PCI0) 1-year and 2-year after operation (P>0.05).@*CONCLUSION@#According to this study, good clinical effects were obtained within 2-year after pulpotomy of adult permanent teeth with MTA and iRoot. In some cases, the root canal system had a tendency of calcification aggravation, and there was no statistical difference in the development of this trend between the two groups.

ABSTRACT

ABSTRACT Objective: To verify, through clinical and radiographic evaluations, the in vivo response of the dentin-pulpal complex of human primary teeth after pulpotomy with MTA and Biodentine™ in a follow-up period of 3, 6, and 12 months. Material and Methods: Thirty teeth were divided into MTA pulpotomy (n = 15) and Biodentine™ pulpotomy (n = 15) from children between 5 and 9 years of age, a randomized clinical trial with simple random sampling. The materials were inserted into the cavity after opening and removing the coronary pulp tissue. The cavity base consisted of glass ionomer cement and light-cured composite resin restoration. Clinical and radiographic analyses were performed after 3, 6, and 12 months. Statistical analysis by Fisher's exact test for dichotomous data at a 5% significance level was utilized. Results: Both materials caused color change after 12 months. However, MTA showed a higher percentage than Biodentine™ (p<0.0001). Pain was detected only with Biodentine™ at six months and mobility at 12 months (p=0.0013). Radiographically, after 12 months, periapical lesions, interradicular lesions, and internal resorption were evidenced in 13% of the cases for Biodentine™-treated teeth (p<0.0013). MTA induced pulp calcification in 13% of cases, unlike Biodentine™ (p<0.0013). Conclusion: BiodentineTM and MTA are suitable for clinical use in pulpotomy treatment, yet both materials lead to tooth discoloration.

ABSTRACT

ABSTRACT Objective: To compare the clinical and radiographic success rates of formocresol, BiodentineTM, and Endo Repair agents in primary molars after 12 months. Material and Methods: This randomized double-blind clinical trial was conducted on healthy children referred to the Department of Pediatric Dentistry, Kerman, Iran, in 2018. One hundred twenty children (human primary molar teeth) aged 3-9 years were selected and randomly divided into three interventions (with pulpotomy medicament agents), including formocresol, BiodentineTM, and Endo Repair. All pulpotomized teeth were restored using stainless steel crowns and evaluated clinically and radiographically during a 12-month follow-up. Fisher exact test was used to determine the association of categorical variables and the data were analysed with SPSS 25. Results: All the available teeth in formocresol and BiodentineTM groups obtained clinical success, whereas 62.5% of the Endo Repair group was successful in this regard. Radiographic success rates of the formocresol, BiodentineTM, and Endo Repair groups were 94.7%, 70%, and 28.1% after a 12-month follow-up, respectively. Moreover, pulp canal obliteration was observed in 26.3%, 25%, and 12.5% of the formocresol, BiodentineTM, and Endo Repair groups. Conclusion: This study reported a high rate of clinical success using both BiodentineTM and formocresol pulpotomy techniques. However, the radiographic success rate of formocresol was higher than that of BiodentineTM, and Endo Repair was not considered a suitable pulpotomy medicament agent.

ABSTRACT

Las altas tasas de lesiones cariosas en niños y adolescentes pueden resultar en la exposición pulpar o incluso en la pérdida temprana del diente primario, situación que requiere una acción mínimamente invasiva por parte del odontólogo, para preservar el diente en la cavidad bucal. La pulpotomía, un tipo de terapia pulpar vital destinada a tratar de forma reversible las lesiones relacionadas con la cámara pulpar, utiliza diferentes técnicas para mantener el diente vital en la cavidad oral hasta la exfoliación. Objetivo: demostrar la efectividad de la técnica de Terapia Láser de Baja Intensidad (LBI) en comparación con el Hidróxido de Calcio en el procedimiento de pulpotomía de dientes primarios. Materiales y Métodos: La investigación fue un ensayo clínico longitudinal con nueve molares primarios de niños de 5 a 12 años. Las evaluaciones clínicas y radiográficas se realizaron después de períodos de 1, 2, 3 y 6 meses. Resultados: Hubo un índice de éxito clínico en cuanto a ausencia de dolor, sensibilidad a la percusión, inflamación y, radiográficamente, ausencia de resorción interna o externa o lesiones de furca en el 100% de los casos. Conclusión: El LBI demuestra beneficios como la ausencia de dolor, el efecto antiinflamatorio y la ausencia de efectos adversos. Por tanto, se sugiere que la LBI puede considerarse una técnica alternativa para la pulpotomía en la práctica clínica. Sin embargo, se recomiendan más estudios clínicos sobre el tema


: Os índices elevados de lesões cariosas em crianças e adolescentes podem resultar em exposição da polpa ou até mesmo na perda precoce do dente decíduo, situação que exige atuação minimamente invasiva do cirurgião-dentista, visando preservar o dente na cavidade bucal. A pulpotomia, um tipo de terapia pulpar vital que visa tratar de forma reversível as injúrias relacionadas à câmara pulpar, utiliza diferentes técnicas com a finalidade de manter o dente vital na cavidade bucal até a sua esfoliação. Objetivo: evidenciar a eficácia da técnica de Laser terapia de Baixa Intensidade (LBI) comparada com o Hidróxido de Cálcio no procedimento de pulpotomia de dentes decíduos. Materiais e método: A pesquisa foi um ensaio clínico longitudinal com nove molares decíduos de crianças com idade entre 5 e 12 anos. Foram realizadas avaliações clínicas e radiográficas após os períodos de 1, 2, 3 e 6 meses. Resultados: Observou-se índice de sucesso clínico quanto à ausência de dor, de sensibilidade à percussão, de inchaço anormal e, radiograficamente, de ausência de reabsorção interna ou de externa ou lesão de furca em 100% dos casos. Conclusão: O LBI demonstra benefícios como a ausência de dor, o efeito anti-inflamatório e a ausência de efeitos adversos. Desta forma, sugere-se que o LBI possa ser considerado uma técnica alternativa para pulpotomia na prática clínica. Porém recomenda-se mais estudos clínicos sobre o assunt


The high rates of carious lesions in children and adolescents can result in pulp exposure or even early loss of the primary tooth, a situation that requires minimally invasive action by the dentist, in order to preserve the tooth in the oral cavity. Pulpotomy, a type of vital pulp therapy aimed at reversibly treating injuries related to the pulp chamber, uses different techniques in order to keep the vital tooth in the oral cavity until exfoliation. Aim: to demonstrate the effectiveness of the Low Intensity Laser Therapy (LBI) technique compared to Calcium Hydroxide in the pulpotomy procedure of primary teeth. Materials and methods: The research was a longitudinal clinical trial with nine primary molars of children aged 5 to 12 years. Clinical and radiographic evaluations were performed after periods of 1, 2, 3 and 6 months. Results: There was an index of clinical success regarding the absence of pain, sensitivity to percussion, abnormal swelling and, radiographically, the absence of internal or external resorption or furcation lesions in 100% of the cases. Conclusion: The LBI demonstrates benefits such as the absence of pain, the anti-inflammatory effect and the absence of adverse effects. Thus, it is suggested that LBI can be considered an alternative technique for pulpotomy in clinical practice. However, further clinical studies on the subject are recommended

ABSTRACT

OBJECTIVE@#To evaluate the clinical characteristics and effectiveness of pulpotomy in mature permanent teeth with bioceramic putty repairmen iRoot and mineral trioxide aggregate (MTA).@*METHODS@#Pulpotomy was performed on mature permanent premolars and molars with carious exposures at the Department of General Dentistry of Peking University School and Hospital of Stomatology, from November 2017 to September 2019. The patients were randomly divided into 2 groups, Group iRoot (n=22) and Group MTA (n=21). In Group iRoot, bioceramic putty repairmen iRoot was used as pulp capping agent, while in Group MTA, mineral trioxide aggregate was used as pulp capping agent. All the patients had signed informed consent forms. The clinical efficacy was evaluated by clinical examinations (temperature and electrical activity test) and imaging examinations 3, 6, and 12 months after surgery. Blinding was used for the patients and evaluators, but due to the obvious differences in the properties of the two pulp capping agents, the blinding method was not used for the treatment provider (the attending physician).@*RESULTS@#There was no significant difference in gender, average age, dentition and tooth position distribution between the two groups (P>0.05). In the study, 7 cases were lost to follow-up 12 months after operation (4 cases in Group iRoot, and 3 cases in Group MTA). One case in each of the two groups had transient sensitivity at the end of the 3-month follow-up, and the pulp vitality was normal at the end of the 6-month follow-up. One case in Group iRoot showed sensitivity at the end of the 12-month follow-up. The success rates of the two groups at the end of 12-month follow-up were 100%, and the cure rates were 94.4% (Group iRoot) and 100% (Group MTA), respectively, and the difference was not statistically significant (P>0.05). No cases in Group iRoot had obvious crown discoloration, while 3 cases in Group MTA had.@*CONCLUSION@#The clinical characteristics and effectiveness of pulpotomy in mature permanent teeth with bioceramic putty repairmen iRoot were similar with MTA. Bioceramic putty repairmen iRoot is an acceptable material when used in pulpotomy of mature permanent teeth. Because it is not easy to cause tooth discoloration after treatment and is convenient to operate, bioceramic putty repairmen iRoot has a better clinical application prospect.

ABSTRACT

Internal root resorption is a pathologic phenomenon with a characterization of the intraradicular dentin destruction due to the abnormal activities of odontoclasts. With its insidious pathology, internal root resorption can progress to a great extent before its clinical detection. The etiology and natural history of internal root resorption are uncertain and the associated key molecular pathogenesis have not been understood completely. The resorption is usually initiated by a stimulus with the loss of the protective predentin and progressed by the continuous stimuli of pulp infection. Various factors including trauma, chronic inflammation of the pulp, pulpotomy and tooth transplantation have been proposed for the occurrence of internal root resorption. The present paper reviews the etiology and pathogenesis of internal root resorption and provides guidance for the early intervention in the clinical practice.

ABSTRACT

In recent years, great progress has been made in research on the treatment of pulpitis, mainly due to the rapid development of basic and clinical researches in this field, and some achievement from basic research has been applied in clinical practice. Advances in the diagnostic methods for pulpitis can help the clinicians to recognize the true state of pulpitis more accurately and to adopt the corresponding treatment methods including indirect/direct pulp capping, pulpotomy, pulp regeneration and root canal therapy. The new theory of pulpitis diagnosis and the studies on immune defense, repair function of dental pulp and new pulp capping materials have significantly improved the success rate of vital pulp therapy. For diffuse coronary pulpitis or radicular pulpitis, which is difficult to achieve vital pulp therapy successfully, methods of pulp revascularization, cell homing and pulp stem cells-mediated pulp regeneration can also be used as treatment options in addition to root canal therapy. The present article focuses on the research progress on pulpitis treatments and related clinical transformation practices, in order to provide reference on vital pulp therapy and pulp regeneration for clinicians.

ABSTRACT

Introdução: O derivado da matriz do esmalte (Emdogain®) é um extrato de proteína usado para cicatrização periodontal. Objetivo: O objetivo desse estudo foi avaliar radiograficamente a resposta pulpar e periapical de dentes de cães após pulpotomia e uso do gel derivado da matriz do esmalte (Emdogain®). Métodos: A pulpotomia foi realizada em 30 dentes (60 raízes) de 3 cães, e o tecido pulpar remanescente foi recoberto com os seguintes materiais: Grupos 1 e 4: gel derivado da matriz do esmalte (Emdogain®); Grupos 2 e 5: hidróxido de cálcio; Grupos 3 e 6: óxido de zinco e cimento de eugenol. Após 10 dias (Grupos 1-3) e 75 dias (Grupos 4-6) foram obtidas radiografias periapicais e a avaliação radiográfica foi realizada considerando-se: a integridade da lâmina dura, presença de áreas de rarefação óssea periapical, reabsorção radicular (interna e externa) e formação de ponte de dentina. Resultados: No período de 10 dias, todos os espécimes dos Grupos 1-3 apresentaram ausência de rarefação óssea periapical, reabsorção radicular (interna e externa) e formação de ponte dentinária. No período de 75 dias, os Grupos 4-6 não apresentaram formação de ponte dentinária em nenhum espécime. Áreas de rarefação óssea periapical foram observadas em 100% das raízes no Grupo 4, 62,5% das raízes no Grupo 6 e em 25% das raízes nos Grupos 5. Conclusão: O uso do gel derivado da matriz do esmalte (Emdogain®) como material para capeamento após a pulpotomia levou à formação de lesões periapicais e não induziu a deposição de tecido mineralizado (AU).


Introduction: The enamel matrix derivative (Emdogain®) is a protein extract used for periodontal healing. The objective of this study was to evaluate radiographically the pulpal and periapical response of dogs teeth after pulpotomy and use of enamel matrix derivative gel (Emdogain®). Methods: Pulpotomy was performed in 30 teeth (60 roots) from 3 dogs and the remaining pulp tissue was capped with the following materials: Groups 1 and 4: enamel matrix derivative gel (Emdogain®); Groups 2 and 5: calcium hydroxide; Groups 3 and 6: zinc oxide and eugenol cement. After 10 days (Groups 1-3) and 75 days (Groups 4-6) periapical radiographs were obtained and the radiographic evaluation was performed considering the integrity of the lamina dura, presence of areas of periapical bone rarefaction, root resorption (internal and external) and dentin bridge formation. Results: In the 10- day period, all specimens in Groups 1-3 presented absence of periapical bone rarefaction, absence of root resorption (internal and external) and absence of dentin bridge formation. In the 75-day period, Groups 4-6 did not present dentin bridge formation in any specimen. Periapical bone rarefaction areas were observed in 100% of the roots in Group 4, 62,5% of the roots in Group 6 and in 25% of the roots in Groups 5. Conclusion: The use of enamel matrix derivative gel (Emdogain®) as a capping material after pulpotomy lead to formation of periapical lesions and did not induce deposition of mineralized tissue(AU).

ABSTRACT

Objetivo: Analizar la eficacia clínica del Agregado Trióxido Mineral (MTA) en pulpotomías a través de estudios comparativos con el formocresol, sulfato férrico e hidróxido de calcio; en pacientes pediátricos con edad de tres a nueve años. Materiales y Métodos: El artículo se basa en una revisión sistemática de la literatura, por ello, se utilizaron como fuentes de información las bases de datos: PubMed, Scielo, y Biblioteca Virtual de Salud. Asimismo, como criterios de inclusión se establecieron publicaciones del año 2008 al 2019, cuya procedencia se derivó de journalsy revistas académicas arbitradas; los cuales permitieron obtener dieciséis ensayos que evaluaban la eficacia clínica a través de los signos y síntomas de las patologías pulpares más comunes: absceso, inflamación gingival, movilidad patológica, dolor a la percusión y dolor espontáneo. Resultados: El MTA obtuvo una eficacia de 97,9% en contraposición al 86,9% del Sulfato Férrico. En relación al Formocresol, el MTA logró el 99% contra un 98,3% de eficacia. Además, en la comparación del MTA con el Hidróxido de Calcio el primero logró un 98,2% y el segundo 74,5%. Conclusiones: El MTA obtuvo una mayor eficacia clínica debido a su biocompatibilidad, pH básico y su elevada facultad al sellar la cámara pulpar. Por lo tanto, puede emplearse como un material seguro para las pulpotomías de pacientes pediátricos.


Objetivo: Analisar a eficácia clínica do Agregado de Trióxido Mineral (MTA) em pulpotomias através de estudos comparativos com formocresol, sulfato férrico e hidróxido de cálcio; em pacientes pediátricos de três a nove anos de idade. Materiais e Métodos: O artigo é baseado em uma revisão sistemática da literatura, portanto, bases de dados foram utilizadas como fontes de informação: PubMed, Scielo, e Biblioteca Virtual. Da mesma forma, como critério de inclusão, foram estabelecidas publicações de 2008 a 2019, cuja origem foi derivada de periódicos e revistas acadêmicas de referência; o que nos permitiu obter dezesseis ensaios que avaliaram a eficácia clínica através dos sinais e sintomas das doenças mais comuns da polpa: abscesso, inflamação gengival, mobilidade patológica, dor na percussão e dor espontânea. Resultados: A MTA obteve uma eficácia de 97,9% contra 86,9% para o sulfato férrico. Em relação ao Formocresol, o MTA alcançou 99% contra 98,3% de eficácia. Além disso, na comparação do MTA com o hidróxido de cálcio, o primeiro atingiu 98,2% e o segundo 74,5%. Conclusões: A MTA obteve uma maior eficácia clínica devido a sua biocompatibilidade, pH básico e sua alta faculdade ao selar a câmara de celulose. Portanto, pode ser usado como material segura para pulpotomias de pacientes pediátricos.


Objective: To analyze the clinical efficacy of the Mineral Trioxide Aggregate (MTA) in pulpotomies through comparative studies with formocresol, ferric sulfate and calcium hydroxide; in pediatric patients aged three to nine years. Materials and Methods: The article is based on a systematic review of the literature, therefore, databases were used as sources of information: PubMed, Scielo, and Virtual Health Library. Likewise, as inclusion criteria, publications from 2008 to 2019 were established, whose origin was derived from journals and refereed academic journals; which allowed us to obtain sixteen trials that evaluated clinical efficacy through the signs and symptoms of the most common pulp diseases: abscess, gingival inflammation, pathological mobility, pain on percussion and spontaneous pain. Results: MTA obtained an efficacy of 97.9% as opposed to 86.9% for ferric sulfate. Concerning to Formocresol, MTA achieved 99% versus 98.3% efficacy. Also, in the comparison of MTA with Calcium Hydroxide, the former achieved 98.2% and the latter 74.5%. Conclusions: MTA obtained a higher clinical efficacy due to its biocompatibility, basic pH and its high faculty when sealing the pulp chamber. Therefore, it can be used as a safe material for pediatric patient pulpotomies.

ABSTRACT

Abstract Caries management at the lesion level is dependent on the lesion activity, the presence of a cavitation (either cleanable or non-cleanable), and lesion depth as evaluated via radiographic examination. A variety of non-invasive, micro-invasive, and minimally invasive treatment (with or without restoration) options are available for primary and permanent teeth. Non-invasive strategies include oral hygiene instructions, dietary counseling, and personal as well as professional use of fluoridated products that reduce demineralization and increase re-mineralization. Micro-invasive procedures include the use of occlusal resin sealants and resin infiltrants, while minimally invasive strategies comprise those related to selective removal of caries tissues and placement of restorations. Deep caries management includes indirect pulp capping, while exposed pulp may be treated using direct pulp capping and partial or complete pulpotomy. The aim of the present study was to review available evidence on recommended preventive and restorative strategies for caries lesions in Latin American/Caribbean countries, and subsequently develop evidence-based recommendations for treatment options that take into consideration material availability, emphasize ways to adapt available treatments to the local context, and suggest ways in which dentists and health systems can adopt these treatments.

ABSTRACT

ABSTRACT Objective: To evaluate the postoperative pain and clinical and radiographic success of pulpotomized primary molars using two materials, Ferric Sulfate (FS) and Calcium-Enriched Mixture (CEM) cement, over a period of 3 and 6 months. Material and Methods: This randomized clinical trial was conducted on a total of 38 teeth selected from 19 patients aged 3-9 years. FS 15.5% and CEM cement were used as pulpotomy agents. Permanent restorations were Stainless Steel Crowns (SSCs) in both groups. Patients were recalled for follow-up at 3 and 6 months intervals for clinical and radiographic assessment. Postoperative pain was recorded by using Visual Analogue Scale up to ten days following the treatment. The data were statistically analyzed using chi-square test and repeated measures ANOVA. Results: At 6 months, a 100% clinical success rate was observed in the FS and CEM cement groups. The radiographic success rate in the FS group was 94.7%, whereas 100% in the CEM cement group at 6 months. No statistically significant difference was found between the two groups (p>0.05). There was no significant difference in postoperative pain between the teeth that received either FS or CEM cement as pulpotomy agents following the procedure (p>0.05). Conclusion: There were favorable outcomes of FS and CEM cement in pulpotomy of primary molar teeth.

ABSTRACT

ABSTRACT Objective: To evaluate the pulp tissue of rat molars after pulpotomies with mineral trioxide aggregate (MTA), BiodentineTM (BDT) and calcium hydroxide (CH) mixed with sterile saline solution (24 hours, 72 hours, 7 days and 15 days), through correlating MPO activity with active neutrophils and MMP8 activity with tissue remodeling. Material and Methods: Thirty-eight Wistar rats were randomly distributed into groups (control, I (MTA gray), II (BDT), and III (CH)) and subdivided according to the study period of 24 hours, 72 hours, 7 days or 15 days after pulpotomy. MMP8 activity was assessed through fluorescence technique, and MPO activity was determined using the MPO assay. Results: A gradual decrease of MPO and MM8 activity occurred in the group MTA over the experimental periods (p<0.05). Groups BDT and CH exhibited an increase in the activity at 7 and 15 days (p<0.05). Conclusion: MTA demonstrated a decrease in the values of MPO e MMP8. BDT and CH showed high neutrophilic and collagenase activity over the experimental periods.

ABSTRACT

RESUMEN: Introducción: La pulpotomía parcial se utiliza para el tratamiento de caries con exposición pulpar en dientes permanentes inmaduros. El agregado de trióxido mineral (MTA) ha sido propuesto como uno de los biomateriales de elección para el tratamiento, pero existe incertidumbre en relación a su efectividad comparado con la del hidróxido de calcio. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Encontramos cinco revisiones sistemáticas, que incluyeron tres estudios primarios, de los cuales todos corresponden a ensayos aleatorizados. Concluimos que la pulpotomía parcial con agregado de trióxido mineral (MTA) podría resultar en poca o nula diferencia en la tasa de éxito comparado a la pulpotomía parcial con hidróxido de calcio, pero la certeza de la evidencia es baja.


ABSTRACT: Introduction: Partial pulpotomy is the treatment of choice following carious pulp exposure in immature permanent teeth. Mineral trioxide aggregate (MTA) has been suggested as the biomaterial first option for treatment, but there is still uncertainty regarding its effectiveness compared to calcium hydroxide. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. Results and conclusions: We identified five systematic reviews including three studies overall, of which all were randomized trials. We conclude that partial pulpotomy with mineral trioxide aggregate (MTA) may make little or no difference to success rate compared to partial pulpotomy with calcium hydroxide, however, the certainty of the evidence has been assessed as low.

ABSTRACT

Loss of teeth vitality when root formation is incomplete, results in weaker structures leaving them prone to fractures and unfavourable long-term prognosis. Apexogenesis is currently the treatment of choice in immature teeth and is indicated in vital teeth without pulpal pathologies. The treatment aims to eliminate the causal agent of the damage, and provide the necessary conditions to preserve vitality in the tooth and induce apical root closure. A 6-year-old male patient was treated at the Endodontics Clinic, Universidad de La Frontera upon complaining of acute pain in tooth 30. The tooth presented incomplete root development due to dental caries with pulp exposure and a diagnosis of irreversible symptomatic pulpitis. Total pulpotomy was performed with the application of Mineral Trioxide Aggregate and controlled at 1, 4, 6, 7 and 12 months, achieving root development and apical closure in the permanent molar. The result was comparable with studies that support this therapy in teeth with irreversible pulpitis. This work seeks to contribute to the existing evidence on the management of immature permanent teeth with irreversible pulpitis to induce root development and apical closure, and maintain pulp vitality.


La pérdida de vitalidad en dientes con formación radicular incompleta trae como resultado el debilitamiento de estos, dejándolos propensos a fracturas con un desfavorable pronóstico a largo plazo. Las terapéuticas actuales de regeneración pulpar en dientes inmaduros estan principalmente indicadas en cuadros de pulpitis irreversible y buscan eliminar el agente causal de daño y brindarle al diente las condiciones y estímulos necesarios para preservar vitalidad e inducir el cierre apical radicular. Un paciente de 6 años de edad y de sexo masculino, acude a la Clínica de Especialidad de Endodoncia de la Universidad de la Frontera, consultando por un dolor agudo en diente 4.6 el cual presentaba un desarrollo radicular incompleto producto de una caries con exposición pulpar con diagnóstico de Pulpitis Irreversible Sintomática. Se realiza una pulpotomia total con aplicación de Mineral Trioxide Aggregate y se controla a los 1, 4, 6 y 7 meses obteniendo un interesante resultado comparable con estudios que avalan dicha terapeutica en dientes con pulpitis irreversible. Este trabajo busca contribuir a la evidencia existente sobre el manejo de dientes permanentes inmaduros con cuadros de pulpitis irreversible para inducir el desarrollo radicular, cierre apical y mantener vitalidad pulpar.

ABSTRACT

Abstract The aim of this study was to evaluate and compare the clinical and radiographic success rates of pulpotomies in primary molars using a new stain-free tricalcium silicate cement (Bio-C Pulpo) versus a conventional white MTA (MTA Angelus) as a pulpotomy medicament for primary teeth. Seventy primary teeth in 33 patients were randomly divided into two groups, MTA Angelus (n = 34) and Bio-C Pulpo (n = 36). Clinical and radiographic follow-up examinations were conducted at seven days (except radiographic follow-up), and at one, three, six and 12 months. At 12 months, the clinical success rate of the MTA Angelus group was 100 percent (28 out of 28), and the radiographic success rate was 100 percent (28 out of 28). In comparison, the clinical success rate for the Bio-C Pulpo group was 100 percent (29 out of 29), and the radiographic success rate was 100 percent (29 out of 29). No significant differences were found between the groups at any follow-up evaluation. According to Fisher´s exact test, a significant difference was observed between the pulpotomy agent and tooth discoloration (p < 0.001). The success rates were 100% for the Bio-C Pulpo group, with no case of discoloration, and 10.31% for the MTA Angelus group. Both MTA Angelus and Bio-C Pulp pulpotomy medicaments are appropriate options for pulpotomies in primary teeth, and enable high clinical and radiographic success rates. However, more long-term studies are required to test the new Bio-C Pulpo medicament.

ABSTRACT

Abstract Objective: To identify the clinical and radiographic conditions associated with failure of pulp therapy in primary teeth through a survival analysis. Material and Methods: A total of 1000 records of children assisted at the pediatric dentistry clinic of the Federal University of Parana, Brazil, from the years 2000 to 2010, were analyzed. The mean evaluation time was 10.61 months (minimum/maximum: 1/28) from the report of pulp therapy. The different types of treatments analyzed included indirect pulp treatment (IPT), direct pulp treatment (DPT), pulpotomy and pulpectomy. The Kaplan-Meyer method and log-rank test were used for the survival analysis. Exodontia was considered as the outcome variable and censors included: traumatic tooth loss, presence of the tooth in the oral cavity and physiologic tooth exfoliation. Results: A total of 122 records reporting pulp therapy in the primary teeth were selected. From this, 16 teeth (13.12%) were extracted. Survival analysis showed that pulpectomy presented lower survival rates when compared to conservative therapies (p=0.0297). Teeth with furcal lesions and pathological root resorption before pulp therapy had lower survival rates when compared to those that did not present these conditions (P=0.006). Presence of fistula and abscess after pulp therapy were also associated with lower survival rates (P=0.0062 and 0.0143, respectively). Conclusion: Signals of pulp necrosis were associated to lower survival rates in primary teeth submitted to pulp therapy.

ABSTRACT

Objective: To evaluate the pulpal and periapical response of dogs' teeth after pulpotomy and use of Enamel Matrix Derivative (EMD) as capping agent. Methods: Pulpotomy was performed in 40 teeth from 4 dogs and the remaining pulp tissue was recovered with the following materials: Groups I and IV: EMD (Emdogain®); Groups II and V: calcium hydroxide; Groups III and VI: zinc oxide and eugenol cement. After 7 days (Groups I, II, and III) and 70 days (Groups IV, V, and VI), the animals were euthanized and the teeth were removed and processed for histological analysis; were analyzed using Kruskal-Wallis test followed by Dunn test or Mann Whitney test ( =0.05). Results: 7-day period: in Group I, it was observed a mild to moderate inflammatory infiltrate and intense vascular proliferation while Group II presented a mild inflammatory infiltrate and an intact pulp tissue (p < 0.05). Group III presented a moderate to severe inflammatory infiltrate. 70- day period: Groups IV and VI showed no dentin bridge formation, the remaining pulp tissue presented necrotic areas with inflammatory cells in the periapical region and bone and cementum resorption (p > 0.05). In Group V, there was dentin bridge formation, absence of inflammation and absence of mineralized tissue resorption (p < 0.05). Conclusion: EMD as a capping material after pulpotomy did not show either satisfactory tissue response or capacity of inducing deposition of mineralized tissue in dental pulp.


Objetivo: Avaliar a resposta pulpar e periapical de dentes de cães após pulpotomia e uso de Derivados de Matriz de Esmalte (EMD) como agente de capeamento. Métodos: A pulpotomia foi realizada em 40 dentes de 4 cães e o tecido pulpar remanescente foi recuperado com os seguintes materiais: Grupos I e IV: EMD (Emdogain®); Grupos II e V: hidróxido de cálcio; Grupos III e VI: cimento de óxido de zinco e eugenol. Após 7 dias (Grupos I, II e III) e 70 dias (Grupos IV, V e VI), os animais foram eutanásiados e os dentes foram removidos e processados para análise histológica; foram analisados pelo teste de Kruskal-Wallis, seguido pelo teste de Dunn ou Mann Whitney ( = 0,05). Resultados: Período de 7 dias: no Grupo I, observou-se infiltrado inflamatório leve a moderado e intensa proliferação vascular, enquanto o Grupo II apresentou infiltrado inflamatório leve e tecido pulpar intacto (p <0,05). O grupo III apresentou infiltrado inflamatório moderado a grave. Período de 70 dias: os grupos IV e VI mostraram, na formação da ponte de dentina, que o tecido pulpar remanescente apresentava áreas necróticas com células inflamatórias na região periapical, reabsorção óssea e de cemento (p> 0,05). No Grupo V, houve formação de ponte de dentina, ausência de inflamação e ausência de reabsorção tecidual mineralizada (p <0,05). Conclusão: O EMD como material de cobertura após pulpotomia não mostrou resposta tecidual satisfatória ou capacidade de induzir deposição de tecido mineralizado na polpa dentária.
