Outcome of curcumin-based photodynamic therapy in endodontic microsurgery: A case report.

INTRODUCTION: Persistent apical periodontitis after root canal treatment may require surgical retreatment when non-surgical options are ineffective or impractical due to anatomical challenges or iatrogenic errors. Endodontic microsurgery (EMS) is a precise technique that aims to overcome extraradicular biofilm and root morphology issues. Photodynamic therapy (PDT) is an emerging supplementary disinfection approach that utilizes a photosensitizer agent and light to eliminate microorganisms through oxidative reactions. REPORT: A 60-year-old male with persistent apical periodontitis in a left maxillary first molar underwent non-surgical root canal retreatment followed by surgical reintervention due to anatomical complexities. During surgery, PDT was performed using a novel curcumin-based photosensitizer agent. After the procedure, the tooth was retrofilled with bioceramic cement, and photobiomodulation was applied to enhance tissue healing. One year post-surgery, the patient exhibited complete periradicular repair and remained asymptomatic. DISCUSSION: EMS is considered a last resort to salvage an endodontically treated tooth and has shown moderate success rates. PDT has demonstrated promise in improving periapical healing and reducing microorganisms. In this case, curcumin, diluted with 2 % chlorhexidine gel, served as an effective photosensitizer agent with antimicrobial properties. Moreover, performing photobiomodulation aided in cell recovery and reduced postoperative discomfort. CONCLUSION: The proposed EMS treatment protocol with PDT using curcumin yielded positive outcomes in this case report. Further randomized clinical trials are necessary to assess the efficacy of this approach in EMS. Additionally, further research on curcumin-based photosensitizer agents encapsulated in nanoparticles and enhanced antimicrobial agents is recommended to refine this treatment protocol for routine use.

Bioactivity Potential of Bioceramic-Based Root Canal Sealers: A Scoping Review.

INTRODUCTION: Bioceramic-based root canal sealers are novel materials with a bioactivity potential that stands out compared with conventional root canal sealers. However, the term bioactivity may be overused and is often misunderstood. Hence, the objective of this study was to synthesize and map key concepts related to the bioactivity analysis of bioceramic-based root canal sealers. METHODS: The present scoping review is reported in accordance with the PRISMA-ScR Statement and is registered in the Open Science Framework. Two blinded reviewers carried out a comprehensive search in six databases up to January 10th, 2022: MEDLINE, Scopus, Embase, Web of Science, Cochrane Library, and Lilacs/BBO. Eligibility was considered for in vitro and in vivo studies that evaluated the bioactivity potential of bioceramic-based root canal sealers. RESULTS: A total of 53 studies were included in the qualitative synthesis. In vitro bioactivity was evaluated through the mineralization potential, formation of carbonated apatite on the surface, and the gene expression related to proteins involved in the mineralization process. Meanwhile, for in vivo studies, staining techniques associated with immunohistochemical tests were mainly used to detect mineralization on the material-host tissue interface. CONCLUSIONS: According to the methodology used, the most prevalent methods to assess bioactivity in acellular form were the immersion of the material in Hank's balanced salt solution, followed by surface observation with scanning electron microscopy and energy dispersive X-ray. In cell cultures, the chosen method was usually Alizarin Red staining, followed by the evaluation of alkaline phosphatase enzymatic activity and the use of molecular biology tests.

Influência do tipo de cimento endodôntico na adesão de pinos de fibra de vidro: revisão de literatura / Influence of the type of endodontic sealer on glass fiber post adhesion: literature review

Introdução: Pinos de fibra de vidro são bastante utilizados quando dentes tratados endodonticamente apresentam grande perda estrutural e necessitam de suporte para a sua reconstrução coronária. A completa adesão do pino à parede do canal radicular é fundamental para o sucesso dessa restauração. Resíduos de cimento endodôntico que permanecem nas paredes dentinárias, mesmo após o preparo para a cimentação, podem interferir negativamente na sua adesão e contribuir para o seu deslocamento. Objetivo: O objetivo da presente revisão de literatura foi avaliar o efeito de diferentes cimentos endodônticos e o tempo decorrido entre a obturação e a cimentação do pino na resistência de união entre o pino e a parede do canal radicular. Métodos: Essa revisão de literatura incluiu 21 estudos que analisaram a influência de cimentos endodônticos na adesão de pinos de fibra de vidro, entre os quais 9 acrescentaram a variável tempo na sua análise, com pinos cimentados logo após a obturação do canal radicular e dias após a obturação. Resultados: Os dentes obturados com cimentos à base de resina demonstraram maior resistência ao deslocamento dos pinos durante os testes. Parece haver uma predominância de menores valores de adesão quando os pinos são cimentados imediatamente após a obturação com cimentos contendo eugenol. Conclusões: Os tipos de cimento endodôntico e o período entre a obturação e a cimentação do pino podem afetar a força de ligação entre a parede do canal radicular e o pino de fibra de vidro (AU).

ntroduction: Glass fiber posts are widely used when endodontically treated teeth present great structural loss and require support for coronal reconstruction. Complete adhesion of the post to the root canal wall is fundamental for the success of this restoration. Endodontic sealer residues that remain on the dentin walls, even after preparation for cementation, may negatively interfere with the adhesion and contribute for post displacement. This literature review evaluated the effect of different endodontic sealers and the time between obturation and post cementation on the bond strength. Methods: This literature review included 21 studies that analyzed the influence of endodontic sealers on the adhesion of glass fiber posts, among which 9 added the variable time in their analysis. Results: Teeth filled with resin-based sealers showed higher post push-out bond strength during testing. There seems to be predominance of lower adhesion values when the posts are cemented immediately after filling with eugenol-containing sealers. Conclusions: The type of endodontic sealer and period between obturation and post cementation can affect the bond strength between root canal wall and the glass fiber post(AU).

Postoperative pain after root canal filling with different endodontic sealers: a randomized clinical trial.

The aim of this randomized clinical trial was to compare the occurrence and intensity of postoperative pain and analgesic intake after root canal treatment, using different root canal sealers. Sixty single-rooted teeth diagnosed with asymptomatic necrosis and apical periodontitis were randomly assigned to 3 experimental groups (n=20), according to the root canal sealer: AH Plus, Endofill or MTA Fillapex. Endodontic treatment was performed in two sessions, and calcium hydroxide was used as the intracanal dressing. Patients were instructed to record pain intensity as none, slight, moderate and severe. Scores from 1 to 4 were attributed to each level of pain after 24 h, 48 h and 7 days. The need for analgesic intake was also recorded. Differences in the incidence of postoperative pain and the need for an analgesic were analyzed using the chi-square test. Differences in pain intensity after treatment were analyzed using the ordinal (linear) chi-square test. No significant differences were detected among the groups in terms of either incidence or intensity of postoperative pain, or need for analgesic intake, at any timepoint (p>0.05). No pain was reported after 7 days. AH Plus, Endofill and MTA Fillapex used for filling root canals resulted in the same rate of postoperative pain and need for analgesic medication.

Correlation Between Volume of Root Canal, Cultivable Bacteria, Bacterial Complexes and Endotoxins in Primary Infection.

This clinical study was conducted to correlate the levels of endotoxins and culturable bacteria found in primary endodontic infection (PEI) with the volume of root canal determined by using Cone Beam Computed Tomography (CBCT); and to evaluate the bacterial diversity correlating with clinical features. Twenty patients with PEI were selected and clinical features were recorded. The volume (mm3) of root canal was determined by CBCT analysis. Root canal samples were analyzed by using kinetic LAL-assay test to determine the levels of endotoxins and anaerobic technique to determine the bacterial count (CFU/mL). DNA was extracted from all samples to determine bacterial diversity and quantified by using Checkerboard-DNA-DNA- Hybridization. Culturable bacteria and endotoxins were detected in 100% of the root canal samples. Linear regression analysis revealed a correlation between root canal volume and presence of anaerobic bacteria (p<0.05). Positive correlations were found between bacteria species and presence of different clinical features (p<0.05). After grouping the bacteria species into bacterial complexes, positive associations were found between green, orange and red complexes with presence of sinus tract (p<0.05). This clinical study revealed that larger root canals hold higher levels of culturable bacteria in PEI. Thus, the interaction of different virulent bacteria species in complexes seems to play an important role in the development of clinical features.

Results: A significant reduction was found in the calcium levels in enamel after treatment with CP + SP and CP (p < 0.05). Carbon (organic part) was hardly altered in enamel. A significant reduction in the calcium levels was found in dentin in Groups HP+SP, CP and CP+SP. Phosphorus levels increased after SP+H20 (p < 0.05) and CP (p < 0.05). Carbon levels showed little variation and the largest amount was found in Groups CP and CP+SP (p < 0.05); in the other groups there was no alteration. A significant reduction in the calcium levels was found in the cementum in Group CP+SP (p < 0.05). Conclusion: Alterations in the enamel, dentin and cementum compositions occurred after bleaching and these alterations showed to be less significant with sodium perborate and water.

Evaluation of the bond strengths of 3 endodontic cements via push-out test.

In this study, the push-out method was used to evaluate the bond strengths of 3 types of endodontic cements according to their composite base: methacrylate, epoxy resin, and an experimental copaiba oil resin. The study hypothesis was that the methacrylate-based and experimental cements would have bond strengths equal to or greater than that of the epoxy resin-based cement. Thirty bovine tooth roots, 18 mm long, were divided into 3 groups (n = 10) based on the chosen cement treatment. After treatment, the specimens were sectioned and submitted to a push-out test. Results showed that there was no statistically significant difference (P < 0.05) between the cements used or between the middle and apical thirds of the roots. It could be concluded that the tested cements had satisfactory and similar bond strengths to dentin.

O objetivo deste estudo foi avaliar o conhecimento e comportamento dos pacientes em atendimento nas clínicas de Endodontia e Dentística da Faculdade de Odontologia de São José dos Campos sobre cárie, doença periodontal e higiene bucal, por meio de um questionário específico e, após avaliação, orientar os participantes da pesquisa. Foram avaliados 430 pacientes adultos com idade entre 18 e 80 anos e os dados obtidos submetidos à análise estatística descritiva. Os resultados mostraram que 72% dos pacientes eram do gênero feminino, sendo predominante a faixa etária entre 41 a 50 anos. Verificou-se que os participantes com maior nível de escolaridade apresentaram mais conhecimento sobre cárie e doença periodontal. Escova e dentifrício foram os recursos mais utilizados para higienização bucal por 56,05% dos entrevistados. A presença de dor (53,03%) foi o fator que motivou a procura pelo atendimento odontológico, enquanto 46,97% foram motivados por atitude preventiva (consulta de rotina). O fio dental é utilizado por 43,95% dos entrevistados, sendo que 46,05% não o utilizamalegando que o mesmo provoca sangramento gengival. Pôde-se concluir que os pacientes avaliadosapresentaram nível de conhecimento desigual sobre cárie, doença periodontal e higiene bucal. O nível de escolaridade teve influência direta sobre o conhecimento e o comportamento dos pacientes em relação às principais doenças da boca. Existe a necessidade contínua de orientação sobre as medidas preventivas para cárie e doença periodontal, ressaltando o papel da dieta e da utilização do fio dental nos programas educativos.

Precisão de métodos radiográficos digitais para odontometria / Accuracy of digital radiographic methods for odontometrics

O uso de radiografias digitais para a realização da odontometria tem ganhado espaço na endodontia, pois possui vantagens como menor tempo de exposição à radiação, manipulação e melhor visualização da imagem pelos softwares, armazenamento em computador, eliminação da película radiográfica e dos líquidos processadores. O objetivo deste estudo foi analisar a confiabilidade da odontometria realizada por diferentes métodos radiográficos digitais comparados à radiografia convencional. Para radiografia digital, foram utilizados os aparelhos RVG Trophy 2000 (Trophy Radiologie, Vincennes - França) e DSX600 (OWANDY Dental Imaging Systems & Software), analisados pelo software Quickvision (Mitutoyo, USA). Neste estudo, foram empregados 50 dentes incisivos inferiores com abertura coronária, da disciplina de Endodontia da Faculdade de Odontologia de São José dos Campos, UNESP. O comprimento dos dentes foi aferido com um paquímetro eletrônico (CD-15CX, Mitutoyo - Japão) e o comprimento do canal radicular com limas endodônticas, medidas tidas como controle. O comprimento de trabalho foi estabelecido com a lima 2mm aquém do ápice radicular. Os dentes com as limas no comprimento de trabalho foram radiografados para posteriormente serem medidos o comprimento do dente e o comprimento de recuo. Por meio dos testes estatísticos ANOVA (5%) e Tukey, foi possível verificar diferenças estatísticas nas medidas do recuo apical quando comparado o controle com o RVG; os demais não demonstraram diferenças significantes entre si. Pode-se concluir que os métodos radiográficos digitais utilizados, apesar de apresentarem diferenças estatísticas, são considerados bons recursos de diagnóstico para a realização de odontometria, podendo ser utilizados com segurança

The use of digital radiographs by odontometrics has been gaining ground in odontology because of its many advantages such as: shorter time of radiation exposure, manipulation and better image visualization by software, computer storage, no need of radiographic film nor processing liquids. The objective of the research was to analyze the reliability of odontometrics performed by different digital radiographic methods as compared to conventional radiography. RGV Trophy 2000 (Trophy Radiologie, Vincennes, France) and DSX 600 (OWANDY Dental Imaging Systems & Software) equipment were used – and analyzed by Quickvision (Mitutoyo,USA) software. Fifty lower jaw incisor teeth with crown opening (that belonged to the Edodontics Course of the São José dos Campos School of Odontology-UNESP) were used in the research. The length of the tooth was measured with an electronic caliper (CD-15CX, Mitutoyo,Japan) and the length of the root canal with edodontics files. These measures were held for experiment control reference. The “working length” was set with a 2mm file below the root tip or apex. Tooth with limes in the working length were radiographed and after that had their length and their “backing up” measured. By using statistical tests ANOVA(5%) and Tukey, it was possible to check statistical differences in the backing up measures when the control measures were compared with the RVG. The other groups did not show any significant differences among themselves. The conclusion is that the digital radiograph methods, in spite of presenting some statistical differences, may be considered a good help for odontometrics and may be safely used.
