Background: Lasers from the erbium family have been investigated to activate irrigation with sodium hypochlorite (NaOCl), improving the disinfection depth of the dentinal tubules of the root canal walls during root canal treatment. However, the possibility of laser-activated irrigation (LAI) in retro-cavity preparation has not been investigated to the date. The aim of our experimental study is to evaluate the efficacy of NaOCl gel penetration inside the dentinal tubules when activated during retro-cavity preparation, comparing passive ultrasonic activation (PUI) and Er,Cr:YSGG LAI. Materials and Methods: Fifty extracted mature single-root human teeth were divided into four groups (control, PUI, and two LAI groups with different NaOCl concentrations). After conventional endodontic treatment and root end resection, NaOCl gel (impregnated with rhodamine dye for confocal laser scanning microscopy (CLSM) analysis) was applied and activated according to the study group. The penetration index and mean penetration length were measured using computer software. Results: Both penetration index and mean penetration length were found to have increased in the PUI group compared to the control samples. However, LAI had a better penetration that was statistically significant compared to both the PUI and control groups. The difference in NaOCl concentration in the laser groups did not affect the penetration values. Conclusions: Within the limitations of our in vitro study using NaOCl gel activation in the retro-cavity after apicectomy, Er,Cr:YSGG LAI significantly enhanced NaOCl gel penetration capacity compared to PUI, regardless of its concentration. LAI can enhance its penetration in a safe way, avoiding its extrusion to the surrounding periapical tissues. [ABSTRACT FROM AUTHOR]

Internal bleaching is a conservative treatment applied to a darkened endodontically treated tooth to restore its original colour, either as a single treatment or as a treatment prior to a subsequent prosthetic phase. The aim of this study was to objectively measure and compare using an experimental model the expansive capacity of four bleaching groups: carbamide peroxide 37% (CP 37%), hydrogen peroxide 30% (HP 30%), HP 30% mixed with sodium perborate (SP) and SP mixed with distilled water. A total of 150 lower incisors (n = 30 in each group) were prepared for the Walking Bleach technique and a glass tube with oil was introduced into the coronal access cavity to measure the expansive capacity through oil displacement, due to the reaction that occurs when bleaching agents interact with dental tissues. The results after 10 days were analysed with the Games–Howell post hoc test to compare the samples. Significant higher expansion was observed with HP 30% (p < 0.05) and lower expansion with SP (p < 0.05) compared to the other groups. No significant differences were observed between CP 37% (p > 0.05) and HP 30% + SP (p > 0.05). This provides significant and observable information on the behaviour of each bleaching group and its evolution after 10 days.

Silver diamine fluoride (SDF) has demonstrated its clinical success for years in the arrest of caries lesions; however, the influence it could have on the success of restorations after its application still remains unknown. The purpose of this research was to study the relationship between the use of SDF and the adhesive strength of the materials used in restorations made with glass ionomers and composite resin, as well as with different adhesive systems. A sample consisting of 240 teeth divided into eight groups with 30 teeth in each of them (n = 30) was used. In these groups, the use of restoration with composite resin and glass ionomer was compared using different adhesive systems, with and without prior application of SDF. Notable differences in adherence were observed among the different groups depending on the filling material. There is also a significant effect of tooth type on adhesion. We can conclude that there is a relationship between the use of SDF and the adhesion between the tooth and the restorative materials analyzed.

Intra-coronal bleaching is a treatment that whitens non-vital teeth from within the pulp chamber, a procedure by which oxygen and free radicals are released. This in vitro study analyzed and compares the oxygen expansion produced when different bleaching agents encounter dental tissues during this type of bleaching. Here, 120 lower incisors were included and prepared to achieve conditions as close as practicable to internal bleaching with the walking bleach technique. The access cavity of the lingual surface was prepared to seal glass tubes with oil inside them by adhesive restoration once the bleach was placed inside the pulp chamber. The following bleaching groups were used: hydrogen peroxide (HP) 30% (n = 30), sodium Perborate (SP) with distilled water (n = 30), a mixture of HP 30% with SP (n = 30) and a control group (n = 30). After 10 days, the oil displacement that took place through the tube due to oxygen release was measured daily. Displacement of the oil was observed in all groups except the control group. The final mean expansion at 10 days was 335.24 ± 76.85 mm for the HP 30% group, 8.40 ± 1.74 mm for the SP group and 183.07 ± 49.93 mm for the HP30% + SP mixture. Significant statistical differences were observed between the three groups using the Games–Howell post hoc test, where HP30% caused the greatest expansion and SP the least expansion. These results suggest that the higher the amount of HP in the sample, the more oxygen expansion is observed, so that temporary restoration must be performed more carefully to avoid displacement.

Internal bleaching is a conservative, non-invasive, and simple treatment that is frequently performed in daily clinical practice. The present in vitro study analyzes the oxygen expansion of different bleaching agents resulting from the oxidation reaction when interacting with enamel and dentin. Enamel and dentin were crushed separately until obtaining a fine powder with particles of an approximate size between 0.06 and 0.2 mm. Each enamel and dentin sample were mixed with 37% carbamide peroxide (CP 37%), 30% hydrogen peroxide (HP 30%), sodium perborate (SP) combined with HP 30% (HP 30% + SP) and SP with distilled water (SP). A total of 280 1 mm diameter glass tubes were used with 70 for each bleaching agent (30 for powdered enamel evaluation, 30 for powdered dentin evaluation, and 10 controls). The bleaching agents were placed in the prepared tubes immediately after mixing the components. As expansion occurred, the oil inside the tube was displaced, through which the resulting expansion was evaluated and measured for 10 days. A significant expansion was observed that varied in magnitude according to the bleaching agent and the tooth structure used. Student’s t test and Welch’s ANOVA were used to analyze the data obtained. The highest mean expansion of both enamel and dentin was observed with 30% HP (66.6 mm for enamel, 94.5 mm for dentin) followed by HP 30% + SP (48.6 mm for enamel, 52.7 mm for dentin), CP 37% (38.4 mm for enamel, 52.6 mm for dentin) and finally SP with water (12.7 mm for enamel, 4.4 mm for dentin). It was observed that the expansion in the SP group with enamel was significantly lower than in the rest of the groups, while that registered for HP 30% was significantly higher. (p < 0.001). The results with dentin were similar, with a significantly lower expansion for SP and higher for HP 30% (p < 0.001). The oxygen expansion observed as a result of the interaction between bleaching agents and dental tissues could contribute to improving our understanding of bleaching and its results. These results suggest that bleaching agents react with the organic component of the tooth structure.

Edentulism produces resorption of alveolar bone processes, which can complicate placement of dental implants. Guided bone regeneration techniques aim to recover the volume of bone. These treatments are susceptible to the surgical technique employed, the design of the autologous block or the tension of the suture. These factors can relate to major complications as the lack of primary closure and dehiscence. The present study, using finite element analysis, aimed to determine differences in terms of displacement of the oral mucosa, transferred stress according to Von Mises and deformation of soft tissue when two block graft designs (right-angled and rounded) and two levels of suture tension (0.05 and 0.2 N) were combined. The results showed that all the variables analyzed were greater with 0.2 N. Regarding the design of the block, no difference was found in the transferred stress and deformation of the soft tissue. However, displacement was related to a tendency to dehiscence (25% greater in the right-angled/chamfer design). In conclusion different biomechanical behavior was observed in the block graft depending on the design and suture tension, so it is recommended to use low suture tension and rounded design. A novel finite element analysis model is presented for future investigations.

Internal medicine ,RC31-1245 - Abstract
Human dental pulp stem cells (HDPSCs) are of special relevance in future regenerative dental therapies. Characterizing cytotoxicity and genotoxicity produced by endodontic materials is required to evaluate the potential for regeneration of injured tissues in future strategies combining regenerative and root canal therapies. This study explores the cytotoxicity and genotoxicity mediated by oxidative stress of three endodontic materials that are widely used on HDPSCs: a mineral trioxide aggregate (MTA-Angelus white), an epoxy resin sealant (AH-Plus cement), and an MTA-based cement sealer (MTA-Fillapex). Cell viability and cell death rate were assessed by flow cytometry. Oxidative stress was measured by OxyBlot. Levels of antioxidant enzymes were evaluated by Western blot. Genotoxicity was studied by quantifying the expression levels of DNA damage sensors such as ATM and RAD53 genes and DNA damage repair sensors such as RAD51 and PARP-1. Results indicate that AH-Plus increased apoptosis, oxidative stress, and genotoxicity markers in HDPSCs. MTA-Fillapex was the most cytotoxic oxidative stress inductor and genotoxic material for HDPSCs at longer times in preincubated cell culture medium, and MTA-Angelus was less cytotoxic and genotoxic than AH-Plus and MTA-Fillapex at all times assayed.

The aim of this paper was to evaluate the intratubular penetration area of a bioceramic sealer, using continuous wave (CW), vertical condensation (VC) with two different types of gutta-percha (conventional (NG) and bioceramic-coated (BG)) and single cone (SC) technique with BG gutta-percha, in different root thirds.A total of 150 mature single-root human teeth (including incisors, canines and premolars) were prepared and randomly divided into five groups (n = 30). Teeth were filled using a bioceramic sealer (TotalFill BC Sealer HiFlow ®) and two different types of gutta-percha, with CW and VC techniques, the teeth in the control group were filled with SC technique and BG gutta-percha. The teeth were sectioned and evaluated as one-third portions in each case under a confocal laser microscope. The penetration area measurements were carried out with the Autocad ® programme. Data was analyzed using the one-factor ANOVA test (p0.05) and Post Hoc Test (p0.05).The ANOVA Test showed significant differences in the penetration areas of the five obturation techniques (P0.05). The Post Hoc Test exhibited significant differences in multiple comparisons (P0.05). There was more dentinal tubule penetration in the coronal third than in the apical third in all techniques.The intratubular penetration of the bioceramic sealer was influenced by the obturation techniques tested, but not by the different gutta-percha tested. There was more penetration of sealer in the warm obturation techniques than the SC, regardless of the type of gutta-percha used.

Although many studies have related smoking to peri-implantitis and marginal bone loss, little is known of its potential impact on dental implant osseointegration. The present clinical study explores the influence of smoking on secondary stabilization based in radiofrequency analysis. A total of 194 implants in 114 patients were included. Implant stability was evaluated on the day of surgery and at a minimum of 90 days after implantation, when osseointegration is considered to have been completed. The evolution of implant stability was compared between 2 groups: smokers and nonsmokers. The following variables were also analyzed: implant brand and model, length, diameter, insertion torque, bone density according to the Misch classification, location of the implant, and patient age and gender. The results showed that smoking did not affect the primary stability of the implant, although it was associated with a marked decrease in secondary stability. The nonsmokers showed a gain of 2.69 points (95% confidence interval [CI]: 1.529–3.865; P < .001) in the osseointegration process. However, in the smokers group, implant stability was seen to decrease 0.91 points (95% CI: −3.424 to 1.600; P < .004), generating a difference of 3.61 points between smokers and nonsmokers. Smoking is thus concluded to be an important factor that must be taken into account when seeking good implant osseointegration outcomes.

PURPOSE. The aim of this study was to compare the radiopacity of 6 modern resin cements with that of human enamel and dentine using the Digora digital radiography system, to verify whether they meet the requirements of ANSI/ADA specification no. 27/1993 and the ISO 4049/2000 standard and assess whether their radiopacity is influenced by the thickness of the cement employed. MATERIALS AND METHODS. Three 3-thickness samples (0.5, 1 and 1.5 mm) were fabricated for each material. The individual cement samples were radiographed on the CCD sensor next to the aluminium wedge and the tooth samples. Five radiographs were made of each sample and therefore five readings of radiographic density were taken for each thickness of the materials. The radiopacity was measured in pixels using Digora 2.6 software. The calibration curve obtained from the mean values of each step of the wedge made it possible to obtain the equivalent in mm of aluminium for each mm of the luting material. RESULTS. With the exception of Variolink Veneer Medium Value 0, all the cements studied were more radiopaque than enamel and dentin (P

Material y método: Se seleccionaron aleatoriamente conos de gutapercha y espaciadores de diferentes tamaños y fabricantes (Dentsply - DeTrey, Dentsply - Maillefer y Boston Dental Scientific). Se conformaron 26 grupos (n: 10). Cada una de las muestras se observó con un microscopio óptico (50-100X), y se midió D1y D2. Los resultados se sometieron a un análisis estadístico descriptivo. Resultados: De acuerdo con nuestros datos, existe variabilidad dimensional entre los conos de gutapercha de un mismo tamaño, los espaciadores y las puntas de gutapercha y los espaciadores entre sí, aunque las diferencias entre este último grupo son menores. Conclusiones: Existen discrepancias dimensionales entre los conos de gutapercha y los espaciadores, las cuales podrían causar inconvenientes durante la obturación tridimensional del sistema de conductos radiculares y propiciar un sellado apical incorrecto. Objective: This study evaluated the dimensional compatibility between guttapercha cones and spreaders. Material and method: Guttapercha cones and spreaders of different sizes and brands were randomly selected (Dentsply / DeTrey, Dentsply / Maillefer and Dental Boston Scientific). 26 groups were made (n: 10). Each sample was observed with an optical microscope (50-100X), and measured at D1 and D2. The results were sujected to a descriptive statistical analysis. Results: According to our data, there was dimensional variability among guttapercha cones of a same size, spreaders and guttapercha points and among spreders, although the differences in the last group were smaller. Conclusions: There are dimensional discrepancies between guttapercha cones and spreaders, which could cause disadvantages during the three dimensional root canal filling and leaf to an incorrect apical sealing.

La aleación utilizada en los diferentes sistemas rotatorios de los que actualmente disponemos condicionan su comportamiento por las propiedades que confiere a la lima. Es por ello, que en el presente estudio se investigan 10 de los sistemas endodóncicos más actuales, y también se agrupan dichos sistemas según la aleación por la cual están fabricados con el fin de valorar su rendimiento a la hora de realizar un tratamiento de conductos radiculares, lo cual realizando un análisis de la literatura científica no hay publicado ningún estudio en el que se comparen juntos los 10 sistemas que se han investigado en este estudio. Dicho rendimiento se valora según el área de corte, la capacidad de centrado/mantenimiento de anatomía, las zonas no instrumentadas, la resistencia a la fractura por fatiga cíclica y la longitud de los fragmentos rotos. El objetivo general fue comparar cuál o cuáles de los actuales sistemas rotatorios y reciprocantes estudiados (F360, iRace, Protaper Next, Reciproc, F6 SkyTaper, Hyflex EDM, Neoniti, Revo-S, One Shape y Wave One Gold), así como sus aleaciones (NiTi convencional, M-Wire, Gold-Wire y CM-Wire) son más eficientes y aportan mayor seguridad a la hora de realizar un tratamiento endodóncico. Los objetivos específicos fueron valorar qué sistema/s y aleación o aleaciones alcanzan el valor más alto de área de corte entre los sistemas de instrumentación endodóncicos F360, iRace, Protaper Next, Reciproc, F6 SkyTaper, Hyflex EDM, Neoniti, Revo-S, One Shape y Wave One Gold, así como de sus aleaciones (NiTi convencional, M-Wire, Gold- Wire y CM-Wire); examinar qué sistema/s y aleación o aleaciones consiguen el porcentaje de dientes más alto en la capacidad de centrado o mantenimiento de la anatomía de los conductos radiculares tanto de los sistemas F360, iRace, Protaper Next, Reciproc, F6 SkyTaper, Hyflex EDM, Neoniti, Revo-S, One Shape y Wave One Gold, como de sus aleaciones (NiTi convencional, M-Wire, Gold-Wire y CM-Wire); determinar qué sistema/s y aleación o aleaciones obtienen el porcentaje de dientes más bajo de zonas no instrumentadas entre los sistemas F360, iRace, Protaper Next, Reciproc, F6 SkyTaper, Hyflex EDM, Neoniti, Revo-S, One Shape y Wave One Gold, y de las aleaciones por las cuales están compuestos (NiTi convencional, M-Wire, Gold-Wire y CM-Wire); estudiar qué sistema/s y aleación o aleaciones consiguen la mayor resistencia a la fractura por fatiga cíclica tanto de los sistemas F360, iRace, Protaper Next, Reciproc, F6 SkyTaper, Hyflex EDM, Neoniti, Revo-S, One Shape y Wave One Gold, como de las aleaciones por las que se componen (NiTi convencional, M-Wire, Gold-Wire y CM-Wire); y valorar qué sistema/s y aleación o aleaciones obtienen el valor más alto en la longitud de los fragmentos rotos en la fatiga cíclica entre los sistemas F360, iRace, Protaper Next, Reciproc, F6 SkyTaper, Hyflex EDM, Neoniti, Revo-S, One Shape y Wave One Gold, así como de sus aleaciones (NiTi convencional, M-Wire, Gold-Wire y CM-Wire). Las conclusiones fueron que el diseño tuvo influencia en el área de corte, siendo F360 inferior en tercio coronal, F360 e iRace en tercio medio; F360, iRace y Protaper Next en tercio apical, y F360 e iRace globalmente. Por otra parte, la aleación también influyó, siendo M-Wire superior en tercio coronal, CM-Wire al NiTi convencional y M-Wire en tercio medio, Gold-Wire y CM-Wire en tercio apical, y M-Wire y CM-Wire al NiTi convencional globalmente; el diseño de los instrumentos no influyó en la capacidad de centrado/mantenimiento de la anatomía, pero sí tuvo influencia la aleación de los mismos, siendo CM-Wire superior en tercio coronal; las zonas no instrumentadas no fueron influidas por el diseño de los instrumentos en tercio coronal, pero sí en tercios medio y apical; siendo superiores en tercio medio Reciproc, Neoniti y Wave One Gold; y en tercio apical Protaper Next, Reciproc, Hyflex EDM, Neoniti y Wave One. La aleación de los instrumentos también influyó, siendo M-Wire y CM-Wire superiores al NiTi convencional en tercio coronal; y M-Wire, Gold-Wire y CM-Wire frente a NiTi convencional en tercios medio y apical; en cuanto a la fatiga cíclica, tanto el diseño como la aleación de los instrumentos sí incidieron, siendo los sistemas con control de memoria (CM-Wire) superiores; y la longitud de los fragmentos rotos sí fue influenciada tanto por el diseño como por la aleación de los instrumentos, obteniendo Reciproc los mayores valores por una parte, y por la otra la aleación M-Wire.

- Abstract
Background: The aim of this study was to assess and compare the push-out bond strength of AH Plus Bioceramic Sealer, TotalFill BC Sealer HiFlow and epoxy resin sealer AH Plus in root canals., Material and Methods: Ninety single rooted teeth with were prepared using rotatory files, 5,25 % sodium hypochlorite and 17% ethylenediaminetetraacetic acid. The teeth were divided into three groups (n=30) and obturated using the single-cone technique with TotalFill BC Sealer HiFlow in Group 1, AH Plus Bioceramic Sealer in Group 2, and AH Plus in Group 3. Three sections (coronal, middle and apical) were obtained for each root (n=270), and the push-out bond strength was evaluated for each section using an universal testing machine. The push-out bond strength among the groups was analysed using the Welch test, while the Mann-Whitney test was used to compare resistance among the coronal, middle and apical thirds of the root., Results: Significant differences were observed between the mean push-out bond strength of the two hydraulic calcium silicate sealers and the resin-based root canal sealer ( P > 0.05). Only Group 1 exhibited significant regional differences among the root thirds, with the apical third demonstrating significantly higher strength values compared to the middle and coronal thirds., Conclusions: Based on the present study, it can be concluded that there are differences in the push-out bond strengths between the two hydraulic calcium silicate sealers (HCSSs) and the resin-based sealer, while no significant difference was found between the two HCSSs. Key words: Push-out bond strength, root canal sealer, root canal obturation, hydraulic calcium silicate cements, bioceramic sealers., Competing Interests: Conflicts of interest The authors declare that they have no conflicts of interest in relation to this study., (Copyright: © 2023 Medicina Oral S.L.)
