Aim: The objective of this bibliometric analysis was to identify and analyze the key characteristics of the 100 most-cited articles related to the use of propolis in dentistry. Methods: The search was conducted in the Web of Science Core Collection, and two independent reviewers selected the articles, excluding meeting articles. The number of citations for each article was compared across the Scopus and Google Scholar databases. The extracted data included the number and density of citations, year of publication, journal and impact factor, study design and theme, country and continent, institution, keywords, and authors. VOSviewer software was employed to generate collaborative network maps. Spearman correlation and Poisson regression analyses were performed on the data. Results: The number of citations ranged from 26 to 247, with a citation density varying between 1.08 and 20.00. Articles were published between 1991 and 2021, with laboratory studies (70%) and antimicrobial activity (39%) being the most prevalent study design and theme, respectively. The most discussed dental specialty was microbiology (49%). Rosalen PL (27%) emerged as the author with the highest number of articles, and the University of Campinas (Brazil) was the most prolific institution. Poisson regression indicated a declining trend in citations over the years, though literature reviews exhibited higher citation performance. Brazil contributed the highest percentage of articles (41%). Conclusion: In conclusion, the 100 most-cited articles predominantly comprised laboratory studies investigating the antimicrobial activity of propolis, primarily originating from Brazil, with notable emphasis on the University of Campinas.

Aim: Calcium-enriched mixture (CEM) cement is an endodontic biomaterial; however, enhancing its physical/mechanical properties remains a challenge. This in vitro study investigates the influence of zirconium oxide (ZrO2) and zinc oxide (ZnO) nanoparticles on the setting time, microhardness, and compressive strength of CEM cement. Methods: Four different groups of CEM cement were prepared: a control group without nanoparticles, two groups with ZrO2 or ZnO, and a group with a combination of nanoparticles. The nanoparticles were added to the powder in predetermined concentrations. The setting time was evaluated using the Gilmore needle method, while microhardness and compressive strength were determined using Vickers hardness and a universal testing machine, respectively. Results: The incorporation of ZnO slightly reduced the setting time, while the addition of ZrO2 significantly prolonged it compared to the control group. Interestingly, the combination of both nanoparticles exhibited a setting time comparable to that of the control group. Regarding the microhardness and compressive strength, both ZrO2 and ZnO significantly improved these properties compared to the control group. The combination of both nanoparticles showed the highest microhardness and compressive strength values among all groups. Conclusions: The addition of nanoparticles to CEM cement effectively modifies its physical and mechanical properties. The optimal combination of these nanoparticles can potentially achieve an improved balance between setting time and enhanced mechanical performance.
目的：富钙混合物（CEM）水门汀是一种牙髓生物材料；然而，提高其物理/机械性能仍然是一项挑战。本体外研究探讨了氧化锆（ZrO2）和氧化锌（ZnO）纳米颗粒对 CEM 骨水泥的凝固时间、微硬度和抗压强度的影响。方法：制备了四组不同的 CEM 水泥：一组为不含纳米颗粒的对照组，两组为含 ZrO2 或 ZnO 的对照组，一组为含纳米颗粒组合的对照组。纳米颗粒按预定浓度添加到粉末中。凝固时间采用 Gilmore 针法进行评估，显微硬度和抗压强度则分别采用维氏硬度计和万能试验机进行测定。结果表明与对照组相比，ZnO 的加入略微缩短了凝固时间，而 ZrO2 的加入则显著延长了凝固时间。有趣的是，两种纳米粒子的组合显示出与对照组相当的凝固时间。在显微硬度和抗压强度方面，与对照组相比，ZrO2 和 ZnO 都明显改善了这些性能。在所有组别中，两种纳米粒子的组合显示出最高的显微硬度和抗压强度值。结论在 CEM 水泥中添加纳米粒子可有效改变其物理和机械性能。这些纳米颗粒的最佳组合有可能在凝结时间和增强的机械性能之间实现更好的平衡。

Aim: To compare performance differences among dental surgeons in the public sector of the state of Minas Gerais regarding prenatal dental care before and after the establishment of Previne Brasil. Methods: A cross-sectional study was conducted, gathering data through a structured questionnaire. The sample consisted of dental surgeons working in the public sector of municipalities in MG and utilizing the snowball effect. Data analysis was performed using the IBM-SPSS® version 29.0, employing Pearson’s Chi-square statistical test (P<0.05). Results: Out of the 28 State Health System (SRS) present in MG. A total of 1696 responses were collected, but after applying the exclusion criteria, 1001 responses remained, specifically related to dental surgeons working in MG public sector. 78.6% comprised professionals who graduated before 2019, while 20.1% graduated after that year. The morning and the second or other gestational trimesters were the most common periods considered optimal for caring for pregnant women. A significant portion of the professionals had not undergone any specific courses or training on this topic, reporting an average satisfaction level of 5.52 regarding the accessibility of information during their education aimed at this audience. Conclusion: Variances were observed in the care provided to pregnant women by dental surgeons working in the public sector of Minas Gerais, distinguishing those trained before and after the implementation of Previne Brasil. The debunking of myths and taboos stands as crucial for enhancing the acceptance of prenatal dentistry.

Music therapy has been used with promising results to reduce pain and anxiety in surgical specialties. It is suggested to reduce anxiety and pain perception during dental surgeries and thereby improving clinical outcomes. Aim: The aim of this study is to determine whether listening to music during trans-alveolar mandibular third molar extraction reduces pain perception and anxiety. Methods: One hundred and forty-six adult participants were randomized into music and non-music groups, with each group comprising seventy-three participants. Each participant had trans-alveolar third molar extraction with or without music intervention depending on the group randomly assigned. Pain scores of participants were measured at one minute after consent, during and after administration of local anaesthetic, during osteotomy, after tooth delivery, and one minute after flap closure. Postoperative pain scores were recorded at one-hour, 3-hour, 6-hour, 24-hour and 48-hour after the last stitch. Pre- and post-operative anxiety scores were also recorded. Descriptive statistics was used to describe sociodemographic data. Student t-test was used to compare the mean of quantitative variables between the groups while chi-square test was used to compare proportions and to investigate association between categorical variables. The statistical significance was defined at p<0.05. Results: The study showed similar sociodemographic characteristics, baseline clinical features and duration of surgery between groups. Pain score peaked during local anaesthetic administration (p = 0.254) and at 3 hours after surgery (p = 0.170) but no statistically significant difference was observed in the mean pain score. The mean anxiety scores also revealed no statistically significant differences. Conclusion: Music was found to add no significant anxiolytic and adjunctive analgesic benefit to participants who underwent third molar surgeries in this study.

Aim: This study aimed to evaluate how different study designs influences the presence and characteristics of diagnosis of oral manifestations in patients with COVID-19. Methods: This study is a meta-search conducted with studies evaluating the relationship between patients with oral manifestations and COVID-19. A search was conducted in three databases (PubMed, Web of Science, and Scopus), using terms specific to COVID-19 and oral lesions, including only primary studies. Study selection was undertaken by two reviewers independently. A descriptive analysis was performed. Results: The results included 55 studies in the data synthesis analysis. Most of the studies were case reports and case series. Some of the studies did not relate a biological test to confirm COVID-19. The ulcer lesion and that clinical examination by specialists were the most reported lesion in case reports and case series studies, while taste alterations and patient self-report were more reported in observational studies. Conclusions: This review concluded that the oral lesions in patients with COVID-19 differ according to the study design. The lack of high-quality scientific evidence in the dental literature on COVID-19 makes the findings inconsistent by the lack of sample selection criteria, diagnostic criteria and classification of oral lesions.

Aim: To report a case of non-neural granular cell tumor (NN-GCT), an uncommon neoplasm, with only six studies worldwide describing cases involving the oral cavity. Methods: A 26-year-old male patient with an erythematous, firm, polypoid nodule in the floor of the mouth that exhibited areas of ulceration and mild bleeding to the touch. A biopsy was performed to aid in the diagnosis. Results: Based on the histopathological and immunohistochemical results (vimentin +, CD68 +, S100 -), the diagnosis was compatible with S100-negative (primitive polypoid non-neural) granular cell tumor. No recurrence was observed over two years of follow-up. Conclusion: The diagnosis of NN-GCT is extremely challenging because this tumor shares histological and immunophenotypic features with many benign and malignant tumors. Although oral NN-GCT may exhibit unusual and atypical histological features, it has an indolent behavior. Thus, until more cases of oral involvement are reported, complete resection and close follow-up are recommended.

Aim: This study aimed to perform an in vitro comparative analysis of the antifungal activity of different calcium silicate-based endodontic sealers against three fungal species. Methods: The antifungal properties of three calcium silicate-based sealers were tested: Bio-C Sealer, Cambiar a Sealer Plus BC, and MTA-Fillapex. Two commonly used sealers were used as controls: AH Plus and Endomethasone. An agar diffusion test was performed to analyze the antifungal activity of the sealers against Candida albicans, Candida glabrata, Candida tropicalis, and a mixed microbial culture medium. The results were analyzed using ANOVA (p <0.05). Results: Endomethasone exhibited the highest inhibition against all strains examined, maintaining a consistent level of inhibition throughout 7 days. MTA-Fillapex demonstrated the best performance among the calcium silicate-based sealers for the three fungal species (p < 0.05), maintaining stable values over the 7 days, surpassing that of Endomethasone. Nevertheless, MTA-Fillapex only exhibited antimicrobial effect against the mixed culture for the first 24 hours, and no antimicrobial activity was observed at 48 hours, being surpassed by all tested sealers (p < 0.05). Conclusion: Of all silicate-based sealers tested, only MTA-Fillapex exhibited promising antifungal activity. Nevertheless, care must be taken when extrapolating these results, as MTA-Fillapex exhibited poor antimicrobial activity when tested in mixed microbial cultures.
目的：本研究旨在对不同的硅酸钙牙髓封闭剂对三种真菌的抗真菌活性进行体外比较分析。方法测试了三种硅酸钙封闭剂的抗真菌特性：Bio-C 封闭剂、Cambiar a Sealer Plus BC 和 MTA-Fillapex。两种常用封闭剂作为对照：AH Plus 和 Endomethasone。琼脂扩散试验分析了封闭剂对白色念珠菌、光滑念珠菌、热带念珠菌和混合微生物培养基的抗真菌活性。结果采用方差分析（P <0.05）。结果显示内美他松对所有受检菌株的抑制率最高，并在 7 天内保持稳定的抑制水平。在硅酸钙封闭剂中，MTA-Fillapex 对三种真菌的抑制效果最好（p < 0.05），在 7 天内保持稳定，超过了 Endomethasone。然而，MTA-Fillapex 只在最初的 24 小时内对混合培养物表现出抗菌效果，48 小时内未观察到抗菌活性，超过了所有测试的封闭剂（p < 0.05）。结论在所有测试的硅酸盐类封闭剂中，只有 MTA-Fillapex 表现出良好的抗真菌活性。不过，在推断这些结果时必须谨慎，因为在混合微生物培养物中进行测试时，MTA-Fillapex 的抗菌活性较差。

Aims: This study aimed to examine the biological response of synthetic nanocomposite material on canine mandibular bone. Methods: Nine healthy adult male local breed dogs aged 12 to 18 months and weighing 10.2 to 15.2 kg were used in the study. Based on healing intervals of 1 and 2 months, the dogs were divided into 2 groups. Each group had 3 subgroups with 3 dogs each. The division was based on the grafting material used to fill the created defect: an empty defect (Control-ve), Beta-Tricalcium Phosphate, and nanocomposite (Beta-Tricalcium Phosphate and nanosilver 1%) . Surgery started after the dogs were anaesthetized. The surgical procedure began with a 5 cm parallel incision along the mandible’s lower posterior border. After exposing the periosteum, a three 5mm-diameter, 5-mmdeep critical-size holes were made, 5mm between each one. Each group’s grafting material had independent 3 holes. The defects were covered with resorbable collagen membranes followed by suturing of the mucoperiosteal flap. Results: Total densitometric analysis showed no significant differences between groups at 1-month intervals, with the nanocomposite group having a higher mean rank (165.66± 31.21) in comparison to other groups while at 2 months intervals that there was a highly significant difference between three groups as the P-value was (0.000) with the nanocomposite group having a higher mean rank (460.66± 26.40). Conclusions: In the current study, the use of nanocomposites improved osteoconductivity by accelerating new bone formation. Moreover, the encorporation of nanosilver enhanced growth factor activity. These attributes make nanocomposites a promising material for enhancing the bone healing process.

Methods: Nine healthy adult male local breed dogs aged 12 to 18 months and weighing 10.2 to 15.2 kg were used in the study. Based on healing intervals of 1 and 2 months, the dogs were divided into 2 groups. Each group had 3 subgroups with 3 dogs each. The division was based on the grafting material used to fill the created defect: an empty defect (Control-ve), Beta-Tricalcium Phosphate, and nanocomposite (Beta-Tricalcium Phosphate and nanosilver 1%) . Surgery started after the dogs were anaesthetized. The surgical procedure began with a 5 cm parallel incision along the mandible’s lower posterior border. After exposing the periosteum, a three 5mm-diameter, 5-mmdeep critical-size holes were made, 5mm between each one. Each group’s grafting material had independent 3 holes.

Aim: This study aimed to review the scientific literature to describe the main care and hygiene protocols for different types of maxillofacial prostheses (MFP). Methods: A bibliographic search on the PubMed / Medline database using the following keywords: [“maxillofacial prosthesis” OR “ocular prostheses” OR “palatal obturators”] AND [“Cleaning” OR “disinfection”] AND [“care”] AND [“color stability”] OR [“denture cleansers” OR “cleansing agents”]. Articles addressing materials, cleaning and disinfection protocols, and care related to MFP were included. The following exclusion criteria were applied: no adequate methodology, incompatibility with the area of interest, and unavailability for reading in full. Results: The papers were grouped into the following topics: facial prostheses, ocular prostheses, maxillofacial intraoral prostheses, and retention systems. Conclusion: Despite the MFP changes over time, its degradation decreases upon following the recommendations and post-adaptation care. The guidelines for cleaning and disinfection must be individualized to guarantee the longevity of the prosthesis and the patient health.

Aim: To evaluate the influence of notebook computers screens and undergraduate level of dental students in the radiographic detection of carious lesions. Methods: Bitewing digital radiographs were presented to 3rd and 5th year dental students in three different notebooks computers: Notebook 1 with anti-glare screen (1366×768 pixels), Notebook 2 without anti-glare screen (1366×768 pixels), and Notebook 3 with anti-glare screen (1920×1080 pixels). A reference standard based on a consensus analysis was set by three senior professors of Oral Radiology and Cariology. Sensitivity, specificity and accuracy values were measured and submitted to two-way ANOVA at a significance level of 5%. Results: Notebook 2 provided significantly lower sensitivity values (Mean 56.5% ± 2.94) than notebook 3 (71.1% ± 2.82) (p = 0.002). We found no statistically significant differences between the two undergraduate years (p > 0.05). Conclusion: The anti-glare screen of notebook computers screens can influence the radiographic detection of carious lesions, but the undergraduate level of dental students does not influence this diagnostic task.
