				<abstract><![CDATA[Dear readersThe Editorial Board of the Journal of Dental Materials and Techniques (J Dent Mater Tech) is pleased to share an important achievement. The journal has received its first Journal Impact Factor of 0.3 according to Clarivate Journal Citation Reports 2025. This marks an important step in the journal&#039;s development and reflects our ongoing efforts to publish high-quality research in dental materials and clinical techniques.This achievement has been made possible through the dedication of many people. We sincerely thank our authors for choosing our journal, our reviewers for their careful evaluations, our Editorial Board members for their guidance, our readers for their continued interest, and our editorial staff for their hard work. We also appreciate the support of Mashhad University of Medical Sciences throughout this journey.Receiving our first Impact Factor is an encouraging milestone, but it is only the beginning. Our goal is to continue improving the quality of the journal, expand collaboration with researchers around the world, and increase our contribution to evidence-based dentistry. We remain committed to maintaining high editorial standards while supporting the publication of valuable scientific research.As the journal has grown, we have continued to improve our editorial and peer-review processes. Over the past five years, the manuscript rejection rate has increased from about 45% to approximately 80%. This reflects our commitment to selecting studies that are scientifically strong, clinically relevant, and in accordance with the journal&#039;s scope. The most common reasons for rejection are that manuscripts do not meet the required scientific standards or fall outside the scope of the journal. Every submission undergoes careful editorial evaluation and independent peer review to ensure that accepted articles meet our scientific and ethical standards.We warmly invite researchers, clinicians, and academic institutions from all countries to submit their best work to the Journal of Dental Materials and Techniques. We believe that international collaboration and the exchange of scientific knowledge will help improve the quality, diversity, and global reach of the journal.We also encourage researchers to read and use the research published in our journal. When articles published in the Journal of Dental Materials and Techniques are relevant to their work, we encourage authors to cite them appropriately. Responsible citation of relevant research helps share scientific knowledge, increases the visibility of valuable scientific findings, and supports the continued growth of the journal.Thank you once again to everyone who has contributed to the success of the Journal of Dental Materials and Techniques. We look forward to working with the international dental research community to advance research and improve patient care through high-quality scientific publications.Sincerely Farzaneh AhrariEditor-in-ChiefJournal of Dental Materials and Technique]]></abstract>

				<abstract><![CDATA[Objective: This study assessed the short-term pulp tissue response to carbonated hydroxyapatite (CHA) when used for direct pulp capping, in comparison with mineral trioxide aggregate (MTA).Methods: In this animal study, class V cavities were prepared on the labial surfaces of 30 maxillary incisors from 30 Sprague–Dawley rats. The animals were randomly assigned into three groups (n=10) based on the pulp‑protective material applied: Group 1: CHA, Group 2: MTA, and Group 3: No capping material (negative control). Following material placement, the cavities were restored with reinforced zinc oxide-eugenol cement. The animals were euthanized at 7 and 14 days postoperatively (n=5), and histological evaluation was conducted to assess the degree of pulpal inflammation and the integrity of the odontoblastic layer.Results: At both 7 and 14 days postoperatively, the control group showed histological features consistent with chronic inflammation, whereas the CHA and MTA groups exhibited preserved pulp tissue architecture and an intact odontoblastic layer. Significant differences in inflammatory scores and odontoblastic layer integrity were observed among the groups at both time points (P&lt;0.05). The control group demonstrated significantly higher inflammation and a damaged odontoblastic layer compared with the CHA and MTA groups (P&lt;0.05).Conclusions: CHA elicited pulpal responses comparable to those of MTA at both 7 and 14 days postoperatively. Both materials demonstrated similar levels of inflammation and comparable preservation of odontoblastic layer integrity. These findings suggest that CHA may be a suitable alternative to MTA for early pulp preservation in vital pulp therapy.]]></abstract>

				<abstract><![CDATA[Objective: The present study compared the fracture resistance of mandibular premolars instrumented using ProTaper NEXT, TruNatomy, and Neohybrid nickel-titanium (NiTi) file systems.Methods: In this in vitro study, 56 extracted mandibular premolars were decoronated to obtain standardized root lengths of 16 mm. The samples were divided into four groups (n=14): Group I, no instrumentation (control); Group II, instrumentation with ProTaper NEXT files (Dentsply Maillefer); Group III, instrumentation with TruNatomy files (Dentsply Sirona); and Group IV, instrumentation with Neohybrid files (Orikam Healthcare). Following instrumentation, the samples were obturated using the cold lateral compaction technique with gutta-percha and AH Plus sealer. After one week, a vertical load was applied using a universal testing machine. The maximum load required to cause a root fracture was recorded in Newtons (N). Data were analyzed using one-way ANOVA and Tukey’s post-hoc test at the significance level of P&lt;0.05.Results: The control group exhibited the highest mean fracture resistance (774.31 ± 140.82 N), followed by TruNatomy (732.78 ± 128.24 N), Neohybrid (679.65 ± 185.78 N), and ProTaper NEXT (606.77 ± 144.85 N) groups. ANOVA revealed a statistically significant difference among the groups (P=0.031). ProTaper NEXT showed significantly lower fracture resistance than the control group (P&lt;0.05). The TruNatomy and Neohybrid groups showed no statistically significant differences compared with either the control group or the ProTaper NEXT group (P&gt;0.05).Conclusions: Within the limitations of this in vitro study, all file systems reduced root fracture resistance; however, only ProTaper NEXT caused a significant reduction compared with the control group.]]></abstract>

				<abstract><![CDATA[Objective: This study compared the ability of composite resin and feldspathic porcelain to mask tooth discoloration at different thicknesses, with and without opaquer application.Methods: In this in vitro study, composite resin (VOCO Grandio) and feldspathic porcelain (Noritake Super Porcelain EX-3) specimens (n=20 per material) were prepared in shade A2 at thicknesses of 0.5 and 1.0 mm (n=10 per thickness) and placed over a C4-shade porcelain substrate that simulated a severely discolored tooth. Each specimen was evaluated with and without opaquer application (composite resin opaquer or opaque resin cement, depending on the material). Color was measured according to the CIE Lab* system, and the color difference (ΔE) was calculated between each specimen under the test condition and the intrinsic reference color of the material. Data were analyzed using three-way ANOVA, with the significance set at P&lt;0.05.Results: The porcelain group showed lower ΔE values than the composite resin group at both thicknesses, with and without opaquer application. The three-way ANOVA revealed that thickness, opaquer application, and material type each had a significant effect on ΔE (P&lt;0.001). The thickness–opaquer interaction was also significant (P=0.04). At 0.5 mm thickness, both opaquer application and material type significantly influenced ΔE (P&lt;0.001), whereas at 1.0 mm, the effect of neither factor was significant (P=0.78 and P=0.83, respectively). Conclusions: At a conservative restoration thickness of 0.5 mm, enhanced masking performance was achieved by using feldspathic porcelain instead of composite resin and by applying an opaquer. However, clinically acceptable masking of severe discoloration was not achieved.]]></abstract>

				<abstract><![CDATA[Objective: This study evaluated the push-out bond strength of an epoxy resin-based sealer (AH Plus®) modified with nano-hydroxyapatite (n-HA) and β-tricalcium phosphate (β-TCP), compared with an unmodified control group.Methods: In this in vitro study, β-tricalcium phosphate and nano-hydroxyapatite were synthesized by wet chemical precipitation, sintered, and then combined to obtain biphasic calcium phosphate. The prepared biphasic calcium phosphate was subsequently incorporated into AH Plus sealer at a concentration of 2.5 wt%. Forty-six maxillary anterior teeth were instrumented and randomly assigned to two groups: unmodified AH Plus sealer (control group) and AH Plus sealer modified with 2.5 wt% biphasic calcium phosphate (experimental group). Obturation was performed using the single-cone technique. After storage at 37°C and 100% humidity for 48 hours, 1-mm-thick root slices were prepared from the coronal, middle, and apical thirds and subjected to push-out bond strength testing using a universal testing machine. Failure modes were evaluated under a stereomicroscope.Results: The experimental group showed significantly higher push-out bond strength than the control group (138.74 ± 19.44 N vs. 120.65 ± 19.52 N; P=0.003). Cohesive failure was the most frequent failure mode in the experimental group (39.1%), whereas adhesive failure was the most frequent in the control group (43.5%). However, the difference in failure modes was not statistically significant between the groups (P&gt;0.05).Conclusions: The incorporation of β-TCP and n-HA as biphasic calcium phosphate into AH Plus sealer was associated with significantly higher push-out bond strength compared with the unmodified control, indicating improved resistance to dislodgement from radicular dentin.]]></abstract>

				<abstract><![CDATA[Objective: This study aimed to develop and evaluate a two-stage deep learning framework for automated localization and severity classification of proximal caries on bitewing radiographs according to the radiographic criteria of the International Caries Classification and Management System (ICCMS). Methods: In this retrospective single-center model-development study, 400 bitewing radiographs were retrieved from the picture archiving and communication system of Mashhad University of Medical Sciences, Mashhad, Iran. After quality screening, 350 radiographs were included. Interproximal lesions were labeled by two restorative dentistry specialists, with disagreements resolved by an oral and maxillofacial radiologist. Lesion localization was performed using Faster R-CNN, and severity classification was performed using ResNet-50 V1 and V2. The dataset was divided into training, validation, and test sets containing 278, 36, and 36 radiographs, respectively. Models were evaluated in six-class ICCMS-based severity grading and three-class grouped severity classification. Performance was assessed using accuracy, precision, recall, specificity, F1-score, and mean average precision (mAP).Results: In the three-class task, ResNet-50 V1 achieved the highest accuracy (0.92), while both models showed comparable F1-scores and mAP values. In the six-class task, ResNet-50 V2 outperformed V1, achieving accuracy, precision, recall, specificity, F1-score, and mAP values of 0.84, 0.60, 0.55, 0.93, 0.57, and 0.44, respectively. Performance was strongest for early lesions and lower for advanced classes with fewer annotated examples.Conclusions: The Faster R-CNN and ResNet-50 framework showed preliminary feasibility for automated caries localization and ICCMS-based severity classification on bitewing radiographs. Larger, balanced, multi-center datasets with external validation are required before clinical implementation.]]></abstract>
