Background: This scoping review aims to analyze the impact of rapid high-intensity light-curing on a new bulk-fill resin-based composites (RBCs) designed for this type of polymerization.

Material and methods: This scoping review was reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) and Joanna Briggs Institute Manual of Evidence Synthesis. The methods were registered on the Open Science Framework (). The literature search was conducted in PubMed/MEDLINE, Embase, Web of Science, Scopus and Cochrane Library databases. Eligibility was considered for in vitro and clinical studies evaluating the effects of ultra-fast high-intensity light-curing on a new system of bulk-fill RBCs.

Results: Of 1.688 articles identified, 27 were included in the qualitative synthesis. All studies were conducted in vitro. A total of 2.432 specimens were evaluated. The studies have shown that shortness light-curing may result in similar properties (stress generated by polymerization shrinkage, marginal integrity, and bond strength to dental interface) for the new bulk-fill RBCs.

Conclusions: Therefore, the new bulk-fill RBCs can be light-cured with a short exposure time and high intensity, providing a time-saving benefit in clinical practice, with similar results to standard light-curing in conventional composites, although, its use should be approached with caution in the flowable composite.

Background: Pharmacological therapy has been used as an alternative or complementary approach to surgery in central giant cell granuloma (CGCG) of the jaws. This systematic review examined the effectiveness of pharmacological therapy for CGCG of the jaws, focusing on clinical outcomes.

Material and methods: Electronic searches were performed in six databases. Case reports and/or cases series were included. The Kaplan-Meier survival analysis method was used to evaluate outcomes related to clinical resolution and recurrence. The risk of bias was assessed using the Joanna Briggs Institute tool.

Results: A total of 74 studies comprising 205 cases of CGCG were included. About 65.4% of cases occurred in individuals under 20 years of age. Most of the treated patients were women (61%) and the mandible (72.2%) was the most reported site. Curettage and enucleation before or after pharmacological therapy were reported in 28.3% and 19% of cases, respectively. The main pharmacological agent used was triamcinolone (37.5%). Complete resolution of CGCG was reported at a rate of 77.1%, while side effects were experienced by 9.8% of individuals. The recurrence rate was 6.8%.

Conclusions: Pharmacological therapy may be an effective and safe option for managing CGCG, especially in the young population. Although the overall success rate in achieving complete resolution is encouraging, further controlled studies are needed to refine drug selection and protocols.

Background: This study aimed to evaluate the effect of incorporating date seeds (DS) microparticles on the compressive strength and microhardness of conventional glass ionomer cement properties following aging in artificial saliva.

Material and methods: Date seeds powder was prepared and added to the conventional glass ionomer cement at concentrations of 3% and 5% by weight. To prepare the samples, a silicon mold was utilized, with dimensions of 6 mm in height and 4 mm in diameter. These samples were then divided into three main groups: group I; unmodified GICs serving as the control, group II; GICs with a 3% weight of DS, and group III; GICs with a 5% weight of DS. The compressive strength and microhardness of the samples were subsequently measured and compared across the three groups, after being stored in artificial saliva for two different time intervals: one day and 30 days. Fourier transform infrared (FTIR) analysis was conducted to determine the nature of the DS and the GIC-DS composite. At the same time, a scanning electron microscope (SEM) was employed to investigate the surface characteristics of the samples.

Results: The measurement values after 24 hours showed that the DS addition had significantly increased the compressive strength but had no effect on the microhardness. However, after aging there was a significant increase in the microhardness and a significant decrease in the compressive strength of the DS groups compared to the control group.

Conclusions: The addition of date seeds powder showed an enhancing effect on the microhardness over time but adversely affected the compressive strength of the material. Key words:Artificial saliva, natural resources, waste materials, dental restoration, mechanical properties.

Background: Noncarious cervical lesions (NCCLs) is the dental structure loss unrelated to caries. The aim was to investigate the possible relationship between bruxism, age, gender, daily routine and dietary habits and NCCL, and correlate with sensitivity and position in the dental arch.

Material and methods: 245 patients aged between 18 and 40 participated in the survey, in which a questionnaire focused on parafunctional habits, erosion, abrasion, dental abfraction and acidic diet was conducted. Facial symmetry analysis, masseter hypertrophy, occlusion evaluation, and presence of wear facets and NCCL. Data were expressed as absolute and percentage frequency and were analyzed using the Fisher's Exact/Chi-square tests and a multinomial logistic regression model.

Results: NCCLs was observed in 46.6 % in the participants. Bruxism was observed in 64% of the individuals, and stress in 33%. Wear facets and acidic diets were reported in 75% and 60% of the sample, respectively. There was no significant relationship between NCCL and gender (p = 0.74), bruxism (p = 0.33), stress (p = 0.52), wear facets (p = 0.73), and acidic diets (p = 0.39). Age over 30 years was more strongly associated with NCCL (p< 0.001).

Conclusions: Age showed a direct correlation with noncarious cervical lesions. Factors including gender and dietary and parafunctional habits, such as bruxism, were not differential regarding the presence of NCCL. Key words:Tooth wear, non-carious cervical lesions, bruxism.

Background: Currently, social media emerges as a swift and efficient channel for disseminating knowledge in dentistry; however, it is imperative to assess whether this information aligns with scientific evidence. This study aims to evaluate the quality of information found on public Instagram profiles in São Paulo State, Brazil, regarding the utilization of botulinum toxin (BTx) for bruxism treatment.

Material and methods: The data were categorized into three qualitative groups: information pertaining to bruxism diagnosis, treatment options for bruxism, and the application of BTx for bruxism. Following the selection of pertinent publications, 50 public profiles were included in the analysis. The publications were assessed utilizing the Global Quality Scale (GQS).

Results: A total of 20,546 posts were tallied across the 50 profiles, with 230 relating to bruxism diagnosis, 166 discussing bruxism treatment options, and 78 mentioning the use of BTx for bruxism. Of these 78 posts addressing BTx for bruxism, 61% did not align with current scientific references, while 39% did. GQS analysis disclosed predominantly "poor quality" content (GQS = 2).

Conclusions: It is concluded that the themes of bruxism and BTx are frequently broached on public Instagram profiles, yet the quality of the available information is generally subpar and often lacks scientific substantiation.

Background: Modern management of carious lesions has been targeted upon using remineralizing agents. This study investigated the remineralization potential of apacider gel (AG) and casein phosphopeptide-amorphous calcium fluoride phosphate (CA) on enamel and cementum around the cavosurface area of the ceramic margin.

Material and methods: Seventy-five extracted human mandibular molars were sectioned at 0.8 mm above and below the cemento-enamel junction (CEJ) to remove the CEJ portions and replaced them with glass ceramic disks by bonding them to the crown and root portions with resin cement. The enamel and cementum area of 4x4 mm2 surrounding ceramic was demineralized with Carbopol-907. The demineralized surfaces were treated with either AG or CA, while one group was left with no treatment (NT) and served as control. Vickers microhardness was determined before-, after demineralization, and after remineralization. The percentage of hardness recovery (%HR), and remineralization potential (%RP) were analyzed with ANOVA and Bonferroni's test (α=0.05). Polarized light microscopy (PLM) was assessed for lesion depth. Scanning electron microscopy (SEM) was investigated for surface alterations.

Results: Significant differences in remineralization were found upon various remineralizing agents compared to NT for both enamel and cementum (p<0.05). No significant difference in %HR and %RP was observed between AG and CA (p>0.05). However, AG signified greater decrease in lesion depth and better improvement in surface characteristics for both enamel and cementum than CA.

Conclusions: AG possesses comparable remineralization ability to CA. However, decreasing in carious lesion depth was evinced with using AG more than CA. AG was recommended as a potential remineralization material for handling initial caries for both enamel and cementum.

Background: Orthodontic appliances contain Bisphenol A and are controversial due to its potential risks for human health. Thus, the aim of the present research was to identify the presence of Bisphenol A in the saliva of patients wearing orthodontic appliances.

Material and methods: A systematic search of the literature was conducted in four electronic databases (PubMed, Embase, Scopus, and Web of Science) and a manual search of grey literature. Research was done up to March 2023, without language restrictions. Based on inclusion/exclusion criteria, data were extracted by two independent reviewers.

Results: A total of 2293 potentially eligible articles were identified, of which 8 were finally included. The studies included a total of 238 patients and showed a moderate quality in the PEDro scale. All the devices studied released Bisphenol A into the saliva, with the polycarbonate brackets being the ones that released it for a longer time. The most significant increase occurred in the first 30 minutes after bonding with composites, reaching 697 µg/g. with polycarbonate brackets.

Conclusions: Although a statistically significant increase of Bisphenol A levels in the saliva of orthodontic patients were found, this increase does not exceed the maximum allowable daily intake. Thus, the use of these materials can be considered safe for human health. Key words:BPA, Bisphenol-A, cytotoxicity, Orthodontic materials, Composite resins.

Background: We first reported that intraoral imaging with a color-imaging intraoral scanner could evaluate stained plaques and contribute to oral hygiene instructions. In this study, we aimed to evaluate the effects of red and blue staining on dental hygiene assessment with an intraoral scanner using plaque control record values and plaque-stained areas.

Material and methods: Fifteen patients (six males and nine females, aged 25-85 years) were included in this study. The patients' teeth were stained with a two-tone (blue and red) dental plaque staining solution, and images of their teeth were recorded with an intraoral scanner and a digital camera. The plaque control record was measured by direct viewing, as usual, and on a monitor using intraoral scanner image. In addition, the plaque deposition area was measured using images obtained using an intraoral scanner and images taken by a digital camera.

Results: Most parts were stained red and blue dental plaque staining was also observed. Plaque control record values tended to be higher in the intraoral scanner evaluation than in the direct evaluation. The plaque-stained area was larger in intraoral scanner images than in camera images.

Conclusions: It is possible to use a two-tone plaque-staining solution for oral health evaluation using an intraoral scanner. In the future, we need to investigate cases of blue-stained plaques. Key words:Intraoral scanner, oral hygiene, dental plaque, preventive dentistry.

Background: The present study aimed to identify and analyze the 100 top-cited articles published in oral radiology.

Material and methods: Web of Science was used to conduct a comprehensive search from inception until 22 November 2023 in dental radiology. Basic information of the 100 top-cited articles was recorded. Biblioshiny and VOSviewer tools were employed for conducting thematic map and author keyword, title, and abstract terms analysis to elucidate the research trends and hotspots. Elsevier Scopus database was also used for citation comparisons.

Results: The citation count for the 101 most-cited articles ranged from 105-587. Most of them were original research studies with observational design conducted in diagnosis, dose, geometric measurements, and image analysis topics. Cone beam computed tomography was the most studied radiologic technique as author keyword co-occurrence analysis revealed and appeared as a basic theme for the transdisciplinary research field's development. While making infant steps, artificial intelligence was adequately represented in top cited list, as it received increasing citation numbers in very few years, concentrating the highest citation densities.

Conclusions: Bibliometric analysis of the most affecting publications in oral radiology depicts the science's evolution and enhances the understanding of scientific research progress. Key words:Bibliometrics, citation analysis, oral radiology, top-cited.

Background: Silver diamine fluoride (SDF) application without removing necrotic tissue is an applicable non-invasive measure to primary care practice and may reduce the burden of untreated root caries. This study aims to examine clinical feature change, root caries-related bacteria, and silver penetration of SDF in arresting root caries.

Material and methods: Ten study participants with 16 root carious teeth were included in this study. The clinical characteristics of root caries lesions (plaque deposit, color, hardness, and sensitivity symptom) were recorded. Then root caries samples were collected using a spoon excavator before and 2 weeks after treated with 38% SDF. The amounts of Streptococcus mutans (S.mutans), Actinomyces naeslundii (A. naeslundii), and Lactobacillus casei (L. casei) were determined using real-time PCR. Any tooth sample scheduled for extraction was further analyzed using micro-CT, stereoscopic microscope, and FE-SEM/ EDX to determine the silver penetration.

Results: Most treated samples were darker in color, predominantly turning black (n =15, 93.8%), had increased surface hardness (n =11, 68.8%), were non-sensitive teeth (n=14, 87.5%), and were negative to air blowing (n =12, 75%). Only S.mutans had a significantly lower number of bacteria after 2 weeks (p-value = 0.041). The micro-CT analysis revealed that the silver increased the root carious lesion's density in proportion to its depth. According to a stereoscopic microscope study, silver penetration caused dark bands, appearing along the dentinal tubule toward the dental pulp. An FE-SEM analysis showed that silver was found to be densely deposited on the surface of the lesions and penetrated through the dentinal tubule into the dental pulp direction. EDX mapping confirmed that the increased density was related to silver.

Conclusions: Based on clinical and microbiological profiles, this investigation indicated that SDF is beneficial for controlling root caries, particularly S.mutans reduction. Silver can also penetrate deep into the lesion. Key words:Microbiology, Root caries, Silver diamine fluoride, Silver ion, Streptococcus mutans, Actinomyces naeslundii, Lactobacillus casei.
