One of the problems that dental bone defects commonly face is less biocompatibility. Therefore, it is important to find effective natural dental materials to increase the rate of cell viability. In the present work, a blend of mineralized collagen fiber (MCF)/silica nanoparticles (Si-NPs) is used to develop a dental implant (DI), for their possible application in dental bone repair. This research study was to develop a technique for the fabrication of DI using natural materials. Accordingly, the present work provides DI, essentially by PVA (6g): MCF (1.5g): Si-NPs (0.8g): CaCO3 (1.0g) slurry into DI with other conventional implants. The DI was characterized by its mechanical, physicochemical, and biocompatibility study. The mechanical analysis was statistically different in all three time periods ( p < .05). Surface characterization of DI was carried out before and after immersion in the SBF. The DI was excellent mechanical properties like compressive strength (24.22 ± 0.32 MPa) and elongation at break (16.51% ± 0.71%). The morphology of the DI showed a good pore size observed. Bioactivity test was observed on the Calcium/Phosphate of the DI. The biocompatibility of the study MTT (3-(4,5-dimethyl) thiazol-2-yl-2,5-dimethyl tetrazolium bromide) assay using the MG63 (human osteoblast cell line) has proven to more viable cell on the DI. The study has devised a process for using fish waste in the preparation of DI. The DI with the required strength, biocompatibility, and bone mineralization properties may be tried as a DI in large animals after obtaining the necessary approval.
牙槽骨缺损通常面临的问题之一是生物相容性较差。因此，寻找有效的天然牙科材料来提高细胞存活率非常重要。本研究利用矿化胶原纤维（MCF）/二氧化硅纳米颗粒（Si-NPs）的混合物来开发一种牙科植入物（DI），以便将其应用于牙科骨骼修复。这项研究旨在开发一种使用天然材料制造 DI 的技术。因此，目前的工作主要通过 PVA（6 克）提供 DI：MCF（1.5 克）：Si-NPs（0.8 克）：CaCO3（1.0 克）浆料与其他传统植入物一起制成 DI。对 DI 进行了机械、物理化学和生物相容性研究。所有三个时间段的机械分析均存在统计学差异（P < .05）。在 SBF 中浸泡前后，对 DI 进行了表面表征。DI 具有优异的机械性能，如抗压强度（24.22 ± 0.32 兆帕）和断裂伸长率（16.51% ± 0.71%）。DI 的形态显示出良好的孔径。对 DI 的钙/磷酸盐进行了生物活性测试。使用 MG63（人类成骨细胞系）进行的 MTT（3-(4,5-二甲基)噻唑-2-基-2,5-二甲基四唑溴化物）检测证明，DI 上的细胞存活率更高。这项研究设计了一种利用鱼类废弃物制备 DI 的工艺。具有所需强度、生物相容性和骨矿化特性的 DI 可在获得必要批准后作为 DI 在大型动物中试用。

Aim: This in vitro study evaluated the effect of polishing methods on the color stainability of 3D-printed permanent restorations while immersed in colorant beverages (distilled water, tea, coffee, and red wine) for 30 days. Materials and Methods: A total of 120-disc-shaped samples (10 mm × 1.5 mm) were fabricated using a stereolithography printer (Formlabs 3B, Formlabs, Massachusetts) with a three-dimensional (3D)-printable permanent resin (Permanent Crown, Formlabs, Massachusetts). The samples were polished with mechanical polishing, Optiglaze (GC Dental Products Corp, Aichi, Japan), or Vita Akzent LC (VITA Zahnfabrik, Bad Säckingen, Germany) ( n = 40). Initial color measurements were performed using a spectrophotometer (VITA Easyshade V; Vita Zahnfabrik). Then the samples were divided into four different subgroups depending on beverages immersed in distilled water, coffee, tea, and red wine ( n = 10). After immersion in beverages for 30 days, color measurements were repeated. Color changes were calculated using the CIEDE2000 color change (Δ E 00 ) formula. Δ E 00 was evaluated according to 50:50% color perceptibility (PT 00 = 0.81) and acceptability (AT 00 = 1.81) thresholds. A two-way analysis of variance (ANOVA), Tukey HSD test with Bonferroni adjustment, and paired-sample t-tests were used for statistical evaluation. Results: The highest ΔE 00 was noted in mechanical polishing groups ( p < .001). Red wine caused the most significant discoloration in the mechanical polishing group ( p < .05). ΔE 00 of mechanical polish groups showed a significantly higher color change than the perceptibility and acceptability thresholds ( p < .001). Optiglaze can reduce 3D-printed permanent restoration discoloration caused by all beverages, Vita Akzent LC can reduce discoloration caused by tea and red wine. Conclusion: Glaze materials can reduce the restoration discoloration caused by colorant beverages.

Initially defined by Robinow et al. in 1969, Robinow syndrome is an exceptionally uncommon (1:500,000) hereditary disorder showing five distinct phenotypes. Although skeletal system symptoms are intense in all phenotypes, maxillofacial indications and genital organ hypoplasia are also present. Maxillofacial appearances can be listed as follows: hypertelorism, midface hypoplasia, wide and flat nose, low nasal bridge, downturned oral commissures, low-set ears, and micrognathia. In oral manifestations, gingival hyperplasia, tongue, and dental abnormalities are frequently encountered. The detection of intraoral and extraoral findings by the dentist plays a significant role in the diagnosis of this disease. Additionally, every new case documented will help dentists plan treatment approaches. Therefore, in this case report we aimed to describe the manifestations of a patient with Robinow syndrome who was referred to us by a pediatric cardiologist for her dental treatments and also the treatment approach under general anesthesia.

Aim: Bleaching is reported to have a deleterious effect on the physical properties of composite material. There is a lack of studies evaluating the effect of bleaching on ACTIVA BioACTIVE – RESTORATIVE. The aim of this study was to evaluate the effects of bleaching on the microhardness and modulus of elasticity of ACTIVA BioACTIVE – RESTORATIVE. Materials and methods: In this in vitro study, the effect of bleaching on two restorative materials was tested. The two restorative materials ACTIVA BioACTIVE – RESTORATIVE and 3M Filtek Z350 Xt were subjected to bleaching with two concentrations of carbamide peroxide (15% and 35%). Measurements of Microhardness and Modulus of elasticity were recorded before and after the bleaching procedure. Data were checked for normality using the Shapiro–Wilk test. Unpaired t test was applied to compare mean of different variables across groups ( p < .0001). Results: The microhardness and modulus of elasticity was higher among the 3M Filtek Z350 Xt group when compared to ACTIVA BioACTIVE – RESTORATIVE. Approximately 35% carbamide peroxide showed the least values when compared to 15% carbamide peroxide. Conclusion: Within the limitation of this study it can be concluded that 15% and 35% carbamide peroxide significantly decreased the Microhardness and Modulus of Elasticity of ACTIVA BioACTIVE – RESTORATIVE and 3M Filtek Z350 Xt. The deleterious effect was concentration dependent as more effect was noted with 35% Carbamide Peroxide. Therefore, patients have to be advised that the existing composite restoration might become softer after bleaching.

Aim: To evaluate the palatal donor site after harvesting connective tissue graft with or without platelet-rich fibrin (PRF). Material and Methods: Forty-two patients requiring connective tissue grafting were randomly divided into two groups: the experimental palatal donor site ( n = 21) received PRF before suturing, and the control palatal donor site ( n = 21) was sutured without any PRF. Results: Among 42 enrolled patients requiring connective tissue grafting, 34 patients completed the study. After 10 days, there was an increase in the average thickness of the palatal surgical test site in PRF-treated patients, whereas it decreased in non-PRF-treated patients. Patients’ response and acceptance for the surgical treatment modality in terms of Patient Comfort Score (PCS) and Patient Appearance Score (PAS) showed less discomfort and better/pleasing appearance in the experimental group after treatment as compared with the control group. “Absolute contour match” of the healing lesion to adjacent mucosa was observed in 76.5% of experimental sites, and no “absolute contour match” was observed with the adjacent non-surgical tissue in the control group, whereas, at 3 and 12 weeks, a 100% “absolute match” with the adjacent tissue was observed for all esthetic parameters in both groups. Conclusion: PRF usage at the donor site seems to be a simple less-invasive approach of high significance resulting in more accelerated physiological healing phenomenon and better early healing response.

Background: Patients with Beckwith-Wiedemann syndrome (BWS) often present with macroglossia and aberrant dentoskeletal features, which may increase the prevalence of malocclusion and complicate conventional orthodontic management (OM). The aim was to comprehensively review the available literature regarding the OM of patients with BWS. Materials and Methods: Indexed databases were searched until February 2023. Clinical studies that addressed the dentoskeletal manifestations and OM of patients with BWS were included. A literature search was performed in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. Results: Notably, 8 out of 2,664 initially-identified studies were included. Six of the studies were case reports/case series and two were retrospective clinical studies. A total of 35 patients with BWS who received orthodontic treatment (OT) were included. Common dentoskeletal and soft tissue traits included the presence of macroglossia, obtuse gonial angle, and anterior open bite. Some form of maxillary transverse discrepancy was found in nine patients. The OT modalities that were utilized included extraoral appliances, functional appliances, removable appliances, interarch elastics, and fixed appliances. The outcome of the OT was reported as successful in five studies. The follow-up, as reported by three studies, ranged from 8 months to 6 years, and the results of the OT were maintained. Adjunct interdisciplinary therapeutic procedures included glossectomy, oral physiotherapy, and orthognathic surgery. Conclusions: Based upon limited available evidence, OT in conjunction with tongue reduction surgery and/or myofunctional therapy can be successfully performed in children with BWS to manage various dentoskeletal discrepancies.

Background: Deviated nasal septum (DNS) is an influential variant of the sinonasal region due to its possible association with varied sinonasal pathologies, mid-facial (skeletal or occlusal) disharmonies and orofacial pain disorders. The aim of the study is to document the prevalence of DNS and to observe and assess the radiographic attributes of its types in adults. Materials and Methods: It is a descriptive cross-sectional study in which, after getting ethical approval, computed tomography paranasal sinus volumes of 100 adult subjects are collected from the medical college on the basis of convenience sampling. Paediatric subjects and patients with a previous history of mid-facial trauma, malignancy or surgery are excluded from the study. DICOM data thus collected are retrospectively analysed by RadiAnt DICOM viewer to determine the prevalence of DNS to study its association across gender and with increased (>1 mm) mucosal thickening of the maxillary sinus. DNS is recorded by Mladina’s classification and by septal deviation angle, and association is studied by the Chi-square test and Mann–Whitney U test. Results: The overall prevalence of DNS is 82%. Association of deviated septum with gender and mucosal thickening of the sinus lining is not statistically significant. Overall type V (spur) deviation is most common; however, in subjects with thickened mucosal lining type III (“C” or reverse “C”), deviation is found to be most prevalent. All the cases of type VI deviation have a tilted nasal floor, a finding of dental surgeon’s interest. “Bridging Spur,” an uncommon form of spur deformity, is also recorded in one case. Conclusions: Deviated septum is far more common than straight septum in the adult population. Types III, II and IV are more frequent in subjects with increased mucosal thickening. Association of type VI with tilted floor and rare variants like “Bridging spur” is also reported.

Objectives: The study’s objective is to assess the capacity of 17% EDTA (ethylene diamine tetraacetic acid) and 17% EDTA-S (sodium lauryl sulphate) on periodontally infected root surfaces as well as their capacity to remove the smear layer. Methods: Groups A (EDTA) and B (EDTA-S) were randomly selected from among 40 single-rooted teeth that had to be extracted due to the mobility. Sections of these teeth were subjected to a 3-minute “Active Burnishing Technique” treatment with 17% EDTA and 17% EDTA-S, followed by a 2-minute saline washing, and then investigated by using an electron microscope. The teeth’s root surface changes were evaluated using Sampaio’s Index, surface morphology, smear layer presence, dentinal tubule patency, and other factors. The results of this study were statistically examined using the paired “t” test. The significance threshold was established at P-value = .05. Results: The outcomes demonstrated that Group B benefited statistically from the elimination of the smear layer and the patency of the dentinal tubules ( P < .01). In the EDTA and EDTA-S groups, there were 85.508.75 and 91.706.20 patent dentinal tubules revealed, respectively. The total surface area exposed by EDTA was 163.88 ± 24.68 and EDTA-S was 182.91 ± 28.16 with a P-value <.01. Conclusion: According to the study’s findings, as compared to EDTA, EDTA-S is more successful at exposing dentinal tubules and removing the smear layer, making it a useful root conditioning agent.

Aim: The aim of this study was to evaluate trauma from occlusion in patients undergoing orthodontic treatment through assessment of fremitus, pocket depth, gingival biotype, and occlusal contacts pre-orthodontic treatment (T0) and post-orthodontic treatment (T1). Materials and Methods: This prospective randomized trial included 40 participants selected based on a simple random sampling method, of which 27 were women and 13 were men with ages ranging from 25 to 40 years. All the participants were clinically checked for gingival recession, fremitus, pocket depth, gingival biotype, and occlusal contacts obtained via digital intraoral scans and fed to 3Shape software to perform the occlusal mapping analysis for pre-orthodontic treatment (T0) and post-orthodontic treatment (T1). T-Scan occlusal analysis was performed to check the force levels pertaining to each tooth. A paired t-test was done to find out the changes in fremitus, pocket depth, gingival biotype, and number of occlusal contacts between T0 and T1. Results: Results of paired t-tests showed a statistically significant difference for fremitus between T0 and T1 ( p < .05). Gingival biotype and pocket depth did not show any improvement post-orthodontic treatment (T1) ( p > .05). Number of traumatic occlusal contacts reduced at T1 for incisors and canines showing a statistically significant difference between T0 and T1 ( p < .05). Conclusion: Orthodontic treatment helps in relieving the traumatic occlusal contacts, especially in the incisors and canine regions. As the teeth are relieved from traumatic occlusal contacts, fremitus also has shown to have drastically improved at the end of orthodontic treatment. Gingival biotype and pocket depth might take a longer time to regenerate and improve, which requires long-term observation.

Aim: Factors such as the low pH of acidic foods and beverages can affect long-term clinical success of restorative materials in the oral cavity. The aim of this study was to compare the solubility of Bulk-fill and Conventional Nano-Hybrid Resin Based Composites (RBCs) in different solutions. Material and Methods: A total of 60 cylindrical specimens were prepared from two RBCs (Tetric N-Ceram, Tetric N-Ceram Bulk-fill) and their constant weight was measured. The specimens were divided into six groups ( N = 10) in accordance with RBC type and pH solution (solution 1, 2, 3 with pH = 2.5, 5, 7, respectively), and were immersed in desired solutions for 30 days. Then they were weighed again and solubility levels of the specimens were calculated according to ISO 4049. Data were analysed by two-way ANOVA. The test power was considered at 80%. Results: The type of RBC had no significant effect on solubility; while the effect of PH was significant. Solution 1 caused significantly the highest solubility. No statistically significant differences were found among other groups. Conclusions: Considering the limitations of the laboratory investigations, it was concluded that solubility rate of Bulk-fill and Conventional RBCs was higher in solutions with lower pH. There was no difference among the RBCs. However, the solubility rates of all groups are within the clinically normal range.
