1. Comparative assessment of CBCT and digital radiography in quantifying periapical pathology (in vitro study).
PMID:日期:2026-09-25To compare the diagnostic accuracy of phosphor plate-based digital periapical radiography (DPR) and CBCT in quantifying periapical lesions compared to the reference standard. This in vitro study included 45 premolar teeth with simulated periapical lesions created in dry human mandibles. The lesions were categorized into three groups according to size. All specimens were imaged using DPR with the paralleling technique (70-80kVp, 8mA, 0.16-0.32s). CBCT imaging was performed using the i-CAT Next Generation system (120kVp, 5mA, 26.9s, 0.25mm voxel size). Lesion lengths obtained from both imaging modalities were compared with the actual lesion dimensions (reference standard) to assess diagnostic accuracy. Intra-examiner reliability was evaluated. Group I's mean lesion length was 1.2mm, Group II's was 1.5mm, and Group III's was 1.8mm. In comparison to the reference standard, PR frequently overestimated the length of lesions. CBCT, on the other hand, showed better accuracy, and greater consistency. A propensity to underestimate minor lesions was indicated by the mean CBCT measurement of 1.07 ± 0.20mm at 1.2 mm group (p = 0.020). At 1.5mm, CBCT assessed 1.72 ± 0.19mm (p = 0.001) while no significant difference observed at 1.8mm (p = 0.065). While CBCT is more reliable than PR, its precision is influenced by lesion size, performing most accurately with larger periapical pathologies. Periapical radiography should be interpreted with caution when assessing periapical pathology, as it may lead to overestimation of lesion size. In contrast, CBCT can be regarded as the reference standard, especially for lesions larger than 1.5mm.

2. From dental adhesives to injectable hemostats: a scoping review of antimicrobial biomaterials for oral soft-tissue bleeding.
PMID:日期:2026-09-23The management of acute oral hemorrhage in emergency settings is frequently complicated by saliva, high vascularity, and microbial presence. This scoping review maps the emerging field of multifunctional, dental-inspired biomaterials. The objective is to synthesize evidence on injectable materials providing rapid hemostasis and antimicrobial protection, while acknowledging the current transition from laboratory models to clinical applications. Following PRISMA-ScR guidelines and the Population-Concept-Context (PCC) model, we searched Scopus, PubMed, and Web of Science (updated search date: July 10, 2026). No language restrictions were applied. Two authors independently performed screening and data extraction (Cohen's Kappa = 0.88). Review articles provided thematic context, while 13 primary research studies provided data for performance benchmarking. No formal protocol was registered. Analysis of 13 primary studies reveals a shift toward chitosan and gelatin-methacryloyl (GelMA) matrices. Quantitative synthesis showed a 32%-42% reduction in hemostasis time compared with commercial controls [1, 2], primarily in low-pressure models. Antimicrobial zones of inhibition ranged from 10 to 18 mm. Antimicrobial action was primarily validated against planktonic, single-species cultures, with effectiveness against complex oral biofilms yet to be proven. Current evidence supports the application of these materials for minor-to-moderate hemorrhage. Broad application for major arterial trauma remains a future objective requiring longitudinal safety studies on nanoparticle bioaccumulation and dynamic mechanical validation under arterial pressure.

3. Cuspal displacement, marginal adaptation, and nanoleakage in maxillary premolars restored with a novel auto-cured bulk-fill composite versus a light-cured bulk-fill composite: an in-vitro study.
PMID:日期:2026-09-21STELA is a newly introduced auto-cured bulk-fill composite proposed as an alternative to amalgam. It does not require light activation and provides an unlimited depth of cure, in addition to acceptable esthetic and mechanical properties. To evaluate cuspal displacement, marginal adaptation, and nanoleakage in mesio-occluso-distal (MOD) Class II preparations of maxillary premolars restored with an auto-cured bulk-fill composite compared with a light-cured bulk-fill composite. Sixty maxillary human premolars extracted for orthodontic purposes were randomly assigned to two groups (n = 30) according to the bulk-fill composite used. Standardized MOD Class II preparations were made and restored using either Group 1: STELA Capsule (SDI, Australia) or Group 2: Tetric N-Ceram Bulk Fill (Ivoclar Vivadent, Liechtenstein). Each group was subdivided into three subgroups (n = 10) based on the test performed. In Subgroup 1, cuspal displacement was recorded after post-cavity preparation and at (5 min, 24 h) post-restoration using a digital microscope. The remaining restored specimens underwent thermocycling and mechanical loading. Subsequently, marginal adaptation (Subgroup 2) was examined using scanning electron microscopy. Nanoleakage (Subgroup 3) was evaluated using silver nitrate tracing. Statistical analysis was performed using the independent-samples t-test and Fisher's exact test (P ≤ 0.05). STELA Capsule demonstrated significantly lower cuspal displacement at both 5 min and 24 h post-restoration compared with Tetric N-Ceram Bulk Fill (P < 0.001). Following thermocycling and mechanical loading, STELA Capsule also exhibited better marginal adaptation (P = 0.033) and reduced nanoleakage (P < 0.001) compared with the Tetric N-Ceram Bulk Fill. The STELA composite with its dedicated primer showed favorable laboratory outcomes compared with Tetric N-Ceram Bulk Fill used with Tetric N-Bond. This restorative protocol can serve as a viable clinical alternative to light-cured bulk-fill composites, particularly for restoring MOD Class II preparations in maxillary premolars. The novel auto-cured bulk-fill composite with its dedicated primer demonstrated excellent performance in reinforcing weakened premolars. It exhibited superior results in reducing cuspal displacement, improving marginal adaptation, and minimizing nanoleakage compared to a light-cured bulk-fill composite, indicating its potential for clinical use.

4. Effect of β-tricalcium phosphate grafting on implant stability and peri-implant radiodensity following immediate implant placement in sites with jumping gaps exceeding 2 mm: a randomized controlled trial.
PMID:日期:2026-09-21Whether grafting peri-implant jumping gaps exceeding 2 mm during immediate implant placement improves outcomes remains uncertain. This trial evaluated the effect of β-tricalcium phosphate (β-TCP) grafting on implant stability and peri-implant radiodensity in such sites. In this prospective, parallel-group randomized controlled trial, 16 patients (8 per group) receiving 39 immediate maxillary anterior/premolar implants at sites with a jumping gap exceeding 2 mm were randomized 1:1 to no grafting (control) or injectable β-TCP (test); the patient was the unit of analysis. The pre-specified primary comparison was implant stability quotient (ISQ) at 6 months. Peri-implant radiodensity was monitored on standardized periapical radiographs (grayscale value) at baseline, 3, and 6 months, and quantified by cone-beam CT (CBCT) at 6 months only (ALARA principle); CBCT values are relative, arbitrary gray-value radiodensity, not true Hounsfield units. Between-group differences were analyzed with independent-samples t tests, within-group changes with repeated-measures ANOVA, and group×time interactions with mixed-design ANOVA (α = 0.05). No statistically significant between-group differences were detected in baseline age or jumping-gap width. No significant between-group difference in ISQ was detected at any time point, and the ISQ group×time interaction was not significant (p = 0.49); ISQ increased significantly over time in both groups. Periapical grayscale value increased significantly faster in the test group on unadjusted analysis (group×time interaction, p = 0.009), but this was no longer significant after adjusting for a small baseline difference (ANCOVA, p = 0.39). On 6-month CBCT, radiodensity was significantly higher in the test group (1224.0 ± 237.0) than control (931.9 ± 100.4 arbitrary units; mean difference 292.1; 95% CI 87.7 to 496.5; p = 0.010), a secondary outcome not included in the a priori sample-size calculation. β-TCP grafting of jumping gaps exceeding 2 mm did not significantly affect ISQ or baseline-adjusted periapical grayscale value. The test group showed significantly higher 6-month CBCT-derived radiodensity, but this was not prospectively powered and may partly reflect residual graft material, so it should be interpreted cautiously. Larger, adequately powered equivalence trials are needed before conclusions about grafting necessity can be drawn. ClinicalTrials.gov, NCT07709676. Registered 2026-07-12. Retrospectively registered.

5. Effect of dentin conditioners on biomarker release and microhardness of radicular dentin: an in vitro study.
PMID:日期:2026-09-21This study investigated the effects of various radicular dentin conditioning agents, maleic acid, citric acid, phosphoric acid, and EDTA, on dentin-derived biomarker release and radicular dentin microhardness for regenerative endodontic applications. Sixty single-rooted teeth were processed into dentin cylinders and discs and randomly assigned to five groups (n = 12): 7% maleic acid, 10% citric acid, 37% phosphoric acid, 17% EDTA, and phosphate-buffered saline (PBS) as a negative control. Growth factor release (TGF-β, VEGF, BMP-2) was quantified using ELISA after 24 h incubation. Microhardness changes were evaluated in corresponding dentin cylinders sectioned longitudinally. Maleic acid produced the highest release of TGF-β, VEGF, and BMP-2 (p < 0.001), followed by EDTA, citric acid, and phosphoric acid in a biomarker-dependent hierarchy. Microhardness was significantly affected by the conditioning agent (p = 0.004), with EDTA and maleic acid reducing dentin hardness compared with the control, while citric acid and phosphoric acid showed no significant effect. No significant differences were observed among root thirds (p = 0.169). Dentin conditioning in regenerative endodontics involves a trade-off between biological activation and preservation of structural integrity. Stronger conditioning agents enhance growth factor release but may compromise dentin hardness. Among the tested agents, citric acid demonstrated the most balanced performance, combining effective biomarker release with minimal effects on dentin microhardness. In contrast, phosphoric acid preserved dentin structure but showed limited biological activity, making it less suitable when regenerative signaling is the primary objective. The selection of dentin conditioning agents should not be based solely on their biological signaling potential, as it directly influences the mechanical properties of radicular dentin and may impact regenerative outcomes.

6. Algorithm-based approach to the management of rhino-maxillary mucormycosis: part II of a two-part study.
PMID:日期:2026-09-20Rhino-maxillary mucormycosis (RMM) is an aggressive, life-threatening fungal infection associated with substantial morbidity and mortality. While early diagnosis is universally advocated, robust quantitative evidence delineating how defined diagnostic delays influence objective clinical outcomes remains scarce. This study aimed to quantify the relationship between diagnostic timing and treatment outcomes in RMM and to develop a protocol-driven multidisciplinary algorithm to standardize management. This retrospective case series analyzed patients diagnosed and treated for RMM at the Otolaryngology and Oral and Maxillofacial Surgery clinics of Beni-Suef University between November 2019 and December 2021. Data extraction and statistical analysis were conducted from June 2022 to January 2024. Diagnostic timing was categorized as early (4-7 days), late (8-10 days), or delayed (> 10 days). Primary outcomes included disease prognosis (regression, stabilization, progression, or death) and resolution pattern (favorable or unfavorable). Associations were evaluated using chi-square tests and Cramer's V, with statistical significance set at p < 0.05. Thirty patients were included (mean age 56.53 ± 11.52 years; 60% male). Early diagnosis occurred in 40% of cases, late in 26.67%, and delayed in 33.33%. The overall survival rate was 83.33%. At final follow-up, disease regression was observed in 60% of patients, stabilization in 16.67%, and progression in 6.67%. A statistically significant association was identified between diagnostic timing and disease regression across follow-up intervals, most pronounced at the third postoperative month (χ = 17.47, Cramer's V = 0.56, p = 0.008). Diagnostic timing was also significantly associated with a favorable resolution pattern at the third month (χ = 15.77, Cramer's V = 0.75, p = 0.0004). This association was not statistically significant at six months (p = 0.87). Diagnostic timing demonstrates a significant association with clinical outcomes in RMM. Earlier diagnosis correlates with higher rates of regression and favorable resolution patterns. Adoption of a structured diagnostic and management algorithm may facilitate early triage and coordinated multidisciplinary intervention, contributing to improved outcome standardization in oral and maxillofacial practice. Prospective validation in larger cohorts is warranted.

7. Analysis of the efficacy of AngelAligner A6 mandibular advancer and Twin Block in the treatment of class II malocclusion in growing patients: a prospective clinical study.
PMID:日期:2026-09-19Although the twin block is the most commonly used appliance for the treatment of Class II malocclusion, the clear aligner industry has developed systems with integrated mandibular advancement. The purpose of this study was to evaluate and compare the effects of Twin block appliances, standard AngelAligner clear aligners and AngelAligner A6 mandibular advancement clear aligners as early orthodontic interventions for patients who develop Class II division 1 malocclusion. The study sample comprised 60 patients with a mean age of 12.4 ± 1.3 years, who were divided into three homogeneous groups of 20 patients each and received different treatments: Twin Block (GTB), AngelAligner aligners (GAA) and AngelAligner A6 for mandibular advancement (GA6). Clinical and radiographic assessments were performed at baseline (T0), immediately prior to appliance placement, and repeated after the completion of treatment objectives (T1). Class II malocclusion was corrected with all three appliances. The GA6 and GTB groups showed similar mandibular advancement, with an increase in the SNB angle of 2.1° and 2.3° respectively, and correction to Class I in 85-90% of cases, outperforming the GAA group, which showed an increase in the SNB angle of 1.2° and correction to Class I in 70% of cases. The duration of treatment was shorter in the GA6 group (15.2 months). These findings suggest that the AngelAligner A6 MA and Twin Block are superior for skeletal correction, whereas the standard AngelAligner is effective for milder cases with aesthetic priorities.

8. Improbable healing in endodontics: a case series of favorable outcomes despite adverse prognostic conditions.
PMID:日期:2026-09-18Endodontic prognosis is based on clinical and radiographic factors that estimate the likelihood of treatment success. Because periapical healing reflects complex interactions among microbial, host, anatomical, and treatment-related factors, individual outcomes may occasionally differ from conventional prognostic expectations. This paper aimed to describe and critically analyze favorable outcomes in teeth presenting conditions traditionally associated with reduced probabilities of treatment success. Three clinical cases were described in accordance with the Preferred Reporting Items for Case Reports in Endodontics (PRICE) 2020 guidelines. The cases presented adverse prognostic conditions, including substantial root resorption, inability to achieve apical patency or complete canal instrumentation, overextension of root filling material, absence of a definitive coronal restoration, and lack of recommended periodontal treatment. Despite these conditions, the teeth remained functional and asymptomatic and demonstrated favorable radiographic outcomes during longitudinal follow-up. These cases illustrate that unfavorable prognostic conditions do not invariably result in treatment failure. The reported outcomes neither diminish the importance of established prognostic factors nor validate the treatment limitations encountered. Rather, they emphasize that prognosis is probabilistic and that unusual favorable outcomes should be interpreted cautiously as individual observations.

9. Comparative in vitro evaluation of sonic, passive ultrasonic, and Er: YAG laser-activated irrigation on Enterococcus faecalis reduction and smear layer/debris removal in root canals.
PMID:日期:2026-09-18Persistent intraradicular infection remains a major cause of endodontic treatment failure because conventional syringe irrigation may not adequately reach the apical third, dentinal tubules, and canal irregularities. The aim of this in vitro study was to compare the antimicrobial efficacy and smear layer/debris removal ability of sonic activation, passive ultrasonic irrigation, and Er: YAG laser-activated irrigation using photon-induced photoacoustic streaming (PIPS), relative to conventional syringe irrigation, in prepared root canals infected with a mono-species Enterococcus faecalis biofilm. Sixty extracted single-rooted mandibular second premolars were prepared, sterilized, inoculated with E. faecalis, and randomly allocated to conventional syringe irrigation, sonic activation, passive ultrasonic irrigation, or Er: YAG/PIPS activation (n = 15). All groups received 2.5% sodium hypochlorite. Post-irrigation bacterial load was quantified as log10 CFU/mL, and smear layer/debris removal in the apical, middle, and coronal thirds was assessed by scanning electron microscopy using a five-point score. CFU values were analysed by one-way ANOVA with Tukey's post hoc test, and SEM scores by the Kruskal-Wallis test with Dunn's multiple-comparison test. Inter-examiner agreement was assessed using Cohen's kappa. Statistical significance was set at p < 0.05. Bacterial load differed significantly among groups (F(3, 56) = 85.11, p < 0.001). Mean log10 CFU/mL values were 6.41 ± 0.30 for conventional irrigation, 5.37 ± 0.26 for sonic activation, 4.12 ± 0.24 for passive ultrasonic irrigation, and 4.28 ± 0.27 for Er: YAG/PIPS activation. Passive ultrasonic and Er: YAG/PIPS activation produced significantly lower bacterial loads than sonic activation and conventional irrigation, with no significant difference between the ultrasonic and laser groups (p = 0.452). SEM scores also differed significantly (H = 38.9, p < 0.001). Overall median scores were 4.5 (IQR 4-5), 3 (IQR 3-4), and 2 (IQR 2-3) for conventional, sonic, and both ultrasonic and laser activation, respectively. All tested activation methods improved root canal disinfection and smear layer/debris removal compared with conventional syringe irrigation. Passive ultrasonic irrigation and Er: YAG/PIPS activation were more effective than sonic activation and showed comparable performance. These methods may be useful adjuncts to sodium hypochlorite irrigation, although clinical studies are needed to confirm their clinical effectiveness.

10. Automated measurement of Little's Irregularity Index on intraoral photographs using a convolutional neural network.
10. 使用卷积神经网络在口内照片上自动测量 Little 不规则指数PMID:日期:2026-09-16Quantification of dental irregularities is essential for assessing case severity, evaluating treatment outcomes, and aiding early detection of fixed retainer failure. Measurements are typically performed on casts or digital scans, although manual measurement on intraoral photographs has been explored to enable remote monitoring. This study evaluated automated measurement of mandibular anterior irregularity on intraoral photographs using a deep learning model. A dataset of intraoral occlusal photographs annotated with contact points of mandibular anterior teeth was created to train a neural network model. Individual tooth displacements and Little's Irregularity Index (LII) were computed from these contact points. Annotation reliability was assessed using intraclass correlation coefficients, and agreement between model-derived and reference LII measurements was evaluated using Bland-Altman analysis on an independent test set. A supplementary, exploratory Bland-Altman analysis was performed at the tooth level. An a priori power analysis determined the required size of the test set, based on a predefined equivalence threshold of 2 mm for LII. The model demonstrated precise localisation of contact points, with a mean radial error of 0.55 ± 0.22 mm. Tooth displacement and LII were predicted with mean absolute errors of 0.42 ± 0.32 mm and 1.37 ± 0.89 mm, respectively. For LII, Bland-Altman analysis revealed a significant bias of 1.07 mm, with limits of agreement ranging from -1.36 mm to 3.50 mm. The exploratory tooth-level analysis yielded a bias of 0.21 mm and descriptive limits of agreement ranging from -0.74 mm to 1.17 mm. The neural network enables automated detection of mandibular anterior landmarks and estimation of LII from intraoral photographs. Since the limits of agreement were wider than the predefined equivalence threshold, the proposed model can currently only be recommended as a complementary tool.
