The literature to date has not reported a clear consensus on the optimal length of fiberglass posts for efficient clinical performance when restoring endodontically treated maxillary incisors with severe crown destruction. This study aimed to determine the stress distribution of fiberglass posts at different lengths using finite element analysis. Five 3D finite element models (groups A-E) were created, each representing a restoration system for endodontically treated maxillary central incisors. The models included post-core crowns with crown-root ratios of 1/3, 1/2, 2/3, 4/5, and 1/1. A static load of 100N force was applied to the palatal surface at 45º to the long axis of the tooth. Von Mises values and | maximum stresses in the crown, dentin, resin cement, and post-core were evaluated separately. The maximum stress experienced was A < C < B < E < D. Von Mises stresses were located in the upper and middle buccal thirds and in the apical palatal third of post A, as well as the upper and middle buccal thirds in posts B, C, D, and E. The lowest distribution of maximum and Von Mises stresses was observed in model A.
迄今为止，关于在修复牙髓治疗后牙冠严重破坏的上颌切牙时，玻璃纤维桩的最佳长度应达到怎样的临床效果，还没有明确的共识。本研究旨在通过有限元分析确定不同长度玻璃纤维桩的应力分布。研究人员创建了五个三维有限元模型（A-E 组），每个模型代表一个牙髓治疗上颌中切牙的修复系统。这些模型包括冠根比分别为 1/3、1/2、2/3、4/5 和 1/1 的后核冠。在与牙齿长轴成 45º 角的腭面上施加 100N 的静态载荷。分别评估了牙冠、牙本质、树脂粘结剂和后牙髓的 Von Mises 值和最大应力。A 柱的 Von Mises 应力位于颊中上三分之一处和腭尖三分之一处，B、C、D 和 E 柱的 Von Mises 应力位于颊中上三分之一处和腭尖三分之一处。

Historically, in its beginnings, sodium hypochlorite was only related to the bleaching of garments, however, over the years its use was extended to the medical area thanks to its disinfectant qualities, and its application continued in the field of dentistry, especially in endodontics, so much so that it has come to be considered today the gold standard in endodontic irrigation. This article aims to briefly highlight its importance in endodontics and the qualities that allow its continued use.

The objective of this article was to carry out a systematic review of the literature to determine the different therapeutic uses of chitosan-based hydrogels and their uses in dental therapy, as well as the modification and improvement of dental materials to promote research related to chitosan and its incorporation into dentistry as an adjunct or replacement in some dental treatments. Chitosan is a natural polymer obtained from the deacetylation of chitin, a polysaccharide abundant in nature, which, due to its biocompatibility, high biodegradability, non-antigenicity, and its ease of acquisition, has attracted biomedical interest, including in dentistry. Recent studies have shown that chitosan can be integrated into dental materials to obtain remineralizing effects, such as for antimicrobial agents, osteogenic agents, and pulp regeneration treatment. A bibliographic search was carried out in PubMed from 2018 to 2023. The results showed a wide range of uses for chitosan in the dental field, particularly its use as a remineralizing agent for tooth enamel; It has also been used in tissue regeneration mainly because of its osteogenic activity, as an antimicrobial agent, and as a vehicle for the application of medications. The use of chitosan as a nanobiomaterial is an interesting topic, since chitosan shows potential for new dental materials, either as an active ingredient or as an adjuvant vehicle for other materials.

During the COVID-19 pandemic, pre-internship training of Health Sciences students took on an essential role. The shift to virtual practices and a project-based learning approach brought challenges, but also opened doors for adaptation and learning in a constantly evolving healthcare landscape. To determine the factors associated with the perception of Peruvian health sciences students during the period of isolation due to the COVID-19 pandemic regarding their training prior to hospital internship. A Cross-sectional analytical study was performed. Students from professional schools of health sciences who entered the hospital internship 2022 and students from the year prior to the internship from a Peruvian public university were evaluated. Data collection was performed with a 49-question questionnaire. Female participants were more prevalent with 384 (70.98%) students while the medical career had the highest participation with 152 respondents (28.1%) followed by the dental career with 134 (24.77%). In the adjusted logistic regression model no influence of associated factors on students' perception of their preparedness for hospital internship in the isolation period due to the COVID-19 pandemic was found. Peruvian Health Sciences students self-perceive themselves prepared for hospital internship in Comprehensive Care, Prevention, Collaboration and Self-Learning, but less so in Practical Skills, Understanding Science, Interpersonal Skills and Confidence.

This contemporary review delves into the intricate realm of temporomandibular joint (TMJ) function and dysfunction, shedding light on its multifaceted nature and offering insights into diagnostic and therapeutic strategies. The TMJ, a vital component of the craniofacial complex, plays a pivotal role in everyday activities such as chewing, speaking, and yawning. Understanding its anatomy and physiology is paramount in the treatment and management of TMJ dysfunction. The biomechanics of TMJ function, from the articular disc to the surrounding ligaments and muscles, have been explored comprehensively. A critical aspect of this review revolves around the diverse etiological factors contributing to TMJ dysfunction. Genetic predispositions, parafunctions, occlusal irregularities, and psychological stress are dissected to illuminate the roles of these factors in the development of TMJ disorders. These complexities prompted the need for a robust classification system elucidating the clinical manifestations and diagnostic criteria for various TMJ disorders. Modern diagnostic modalities, including clinical assessment, imaging techniques, and joint aspiration, are scrutinized for their indispensable roles in accurate diagnosis. The comprehensive overview included management strategies, from conservative measures to surgical interventions. In recognizing the pivotal influence of psychosocial factors, this review underscores the importance of patient-centered care and cognitive-behavioral interventions. Furthermore, regenerative therapies, minimally invasive techniques, and personalized medicine are emerging trends in TMJ research. This review provides a contemporary roadmap for comprehending, diagnosing, and managing TMJ-related conditions.

To evaluate the intratubular penetration depth of ultrasound-activated bioceramic sealant cements into root dentin, specifically at the dentin-cement interface. This in vitro experimental study was conducted with samples that were randomly divided based on the type of sealer used and whether ultrasound activation was applied prior to obturation. This resulted in four experimental groups (n=40). Groups A1 and B1 utilized the Eighteeth Ultra X ultrasonic activator with a blue tip #20 featuring a 2% taper at low power for activation, while groups A2 and B2 did not employ any form of activation. The symbol (+) denotes groups with ultrasonic activation, while (-) represents groups without ultrasonic activation. In the middle third, it was observed that BioC Sealer (+) had a mean sealing value of 0.66±0.17, while MTA Fillapex (+) showed a mean value of 0.38±0.07. It was found that BioC Sealer (-) had a mean sealing value of 0.24±0.04 in the middle third, while MTA Fillapex (-) showed a mean value of 0.16±0.04. These differences were not statistically significant (p=0.569). In the apical third, the BioC Sealer (-) presented a mean sealing value of 0.44±0.17, while the MTA Fillapex (-) obtained a mean value of 0.30±0.04. However, this difference did not reach statistical significance (p=0.0745), suggesting that both materials can provide a similar seal in the apical third. The results suggest that both BioC Sealer and MTA Fillapex provide a comparable seal in the middle and apical thirds of the root canal system, however, this was not statistically significant. This indicates their potential efficacy in both endodontic sealing procedures.
评估超声激活的生物陶瓷封闭剂在牙本质内的管内渗透深度，特别是在牙本质-水泥界面处的渗透深度。这项体外实验研究根据所使用封闭剂的类型以及是否在封闭前使用超声波激活来随机划分样本。这样就产生了四个实验组（n=40）。A1 组和 B1 组使用 Eighteeth Ultra X 超声波激活器，其蓝色 20 号针尖具有 2% 的锥度，以低功率激活，而 A2 组和 B2 组未使用任何形式的激活。符号（+）表示使用超声波激活的组别，（-）表示未使用超声波激活的组别。在中间三分之一处，观察到 BioC Sealer（+）的平均密封值为 0.66±0.17，而 MTA Fillapex（+）的平均密封值为 0.38±0.07。 研究发现，BioC Sealer (-) 在中间三分之一处的平均密封值为 0.24±0.04，而 MTA Fillapex (-) 的平均密封值为 0.16±0.04。这些差异没有统计学意义（P=0.569）。在根尖三分之一处，BioC Sealer (-) 的平均封闭值为 0.44±0.17，而 MTA Fillapex (-) 的平均值为 0.30±0.04。然而，这一差异并没有达到统计学意义（P=0.0745），这表明两种材料都能在根尖三分之一处提供相似的封闭效果。结果表明，BioC Sealer 和 MTA Fillapex 都能在根管系统的中间和根尖三分之一处提供相似的密封效果，但这并不具有统计学意义。这表明它们在两种根管封闭程序中都具有潜在的功效。

Ensuring optimal aesthetic outcomes in dental implant cases within the maxillary anterior area requires careful consideration of socket preservation and atraumatic tooth extraction. These factors play a crucial role in achieving successful and aesthetically pleasing treatments. The objective of this study is to present a series of clinical cases involving dental extractions of anterior maxillary teeth with a poor prognosis. This study highlights the importance of socket preservation and atraumatic tooth extraction in ensuring optimal aesthetic results in dental implant cases within the maxillary anterior area. In these cases, a two-armed lever technique was planned for atraumatic alveolar preservation during the extraction process.Following the tooth extraction, the fresh socket was reclassified, and dental implants were subsequently placed using a modified drilling technique in certain cases. The authors assessed the primary stability of the implants, while in other cases, bone regeneration procedures were performed. The presented clinical cases demonstrate the successful implementation of the two-armed lever technique for atraumatic alveolar preservation, leading to favorable outcomes in terms of primary implant stability and bone preservation. Techniques for bone preservation after tooth extraction aim to minimize post-extraction bone resorption. By implementing appropriate protocols, such as the concept of the dual zone and the two-armed lever technique, successful outcomes can be achieved in terms of both aesthetics and preservation of the alveolar bone.

The aim of this study was to find out if there was an association between TPM1 gene polymorphism (rs11071720) and non-syndromic cleft lip and palate in humans. Twenty five patients with non-syndromic cleft lip and palate (NSCL/P) and twenty five healthy patients as controls were enrolled in the study. Whole blood drawn from the participants was used to obtain genomic DNA. Sequence specific primers were used to amplify the region spanning the polymorphic site of the TPM1 gene using polymerase chain reaction (PCR). The genotype of the subjects was identified employing the RFLP technique. The genotype and allele frequency distributions in the non-syndromic cleft lip and cleft palate patients and control groups were compared using Chi-square test. In the NSCL/P, the genotype in the order from highest to lowest frequency was TC (48%), followed by CC (32%) and TT (20%). Although the genotype frequency of the case and the control groups were found to be in agreement with Hardy Weinberg Equilibrium, the genotype frequencies TC, CC and TT of the polymorphism (rs11071720) among the two groups were not statistically significant which was evident from the p-value 0.8472. No significant association was found between TPM1 gene (rs11071720) polymorphism and NSCL/P.

The purpose of this study was to evaluate peri-implant soft tissue response by assessing IL-6, IL-1b and MMP-8 levels in peri-implant crevicular fluid (PICF) around machined vs. laser-microgrooved implants/healing/prosthetic abutments during 1 year of function. Twenty-four patients each received 2 one-stage implants in a split mouth design on the same jaw. In each patient, one implant, one immediate healing, and one prosthetic abutment with a machined surface (M group), and one implant, one immediate healing abutment and one prosthetic abutment with a laser-microgrooved surface (LMS group) were used. PICF sampling, pocket probing depths (PPD) and bleeding on probing (BOP) were assessed at 1, 3, and 12 months. IL-6, IL-1b and MMP-8 levels were determined by specific enzyme-linked immunosorbent assay systems (ELISA). Repeated measure ANOVA was used to run comparisons with groups and between groups months at 1, 3, and 12 months. At 3 and 12 months, the LMS group showed significantly lower PD, BOP and IL-6, IL-1β and MMP-8 levels than the M group (P<.05). This study suggests the presence of more remodeling and/or inflammatory phenomena around implants/abutments with a machined surface than around implants/abutments with a laser-microgrooved surface.

The aim of this case study is to report a successful clinical case of an endo-perio lesion in a tooth with an initially unfavorable prognosis, followed up for 18 months. A male patient, public servant, non-smoker, without a history of diabetes, and married sought dental treatment in 1995 due to periodontal problems. He was then 40 years old and diagnosed with moderate to advanced periodontal disease. The initial treatment consisted of supra and subgingival scaling, followed by the extraction of teeth indicated for removal. After discharge, the patient adhered to a preventive periodic maintenance (PPM) program to control periodontal disease recurrence. In 2021, tooth 43 showed an unfavorable endo-perio lesion during a routine check-up. Despite treatment options, the patient opted for conservative treatment with endodontic and periodontal procedures. Simultaneously, PPM sessions were performed. The patient was monitored every six months, showing regression of periodontal pockets and significant improvement after 18 months. This case highlights the importance of patient adherence to PPM, demonstrating that a conservative approach and proper maintenance can lead to positive clinical outcomes even in cases with an initially unfavorable prognosis.
