Objectives: This study assessed the awareness of dental students and practicing dentists in Turkey regarding forensic odontology and the recognition and reporting of child abuse. Methods: A questionnaire-based cross-sectional study included 406 participants. The 31- item questionnaire covered forensic odontology, child abuse recognition, legal responsibilities, and reporting procedures. A certainty score was calculated from the objectively structured True/False/”I don’t know” items (Q18–Q28), while the remaining items were analyzed descriptively. Descriptive and subgroup analyses evaluated associations between participant characteristics and certainty scores. Internal consistency was assessed using Cronbach’s alpha. Results: The mean certainty score was 5.08 ± 2.74 (range: 0–11), with no significant gender differences (p > 0.05). Cronbach’s alpha indicated acceptable internal consistency (α = 0.74). Many participants were uncertain about medico-legal aspects and reporting procedures. Reporting preferences varied across workplace settings, suggesting inconsistent knowledge of reporting pathways. Conclusions: Although participants demonstrated a general awareness of forensic odontology and child abuse recognition, important uncertainties remained regarding medico-legal responsibilities and reporting procedures. These findings highlight the need to strengthen undergraduate and postgraduate education in forensic odontology and child abuse reporting within dental curricula. However, the findings should be interpreted in light of the study’s exploratory nature and methodological limitations
Objectives: This in vitro study aimed to compare the accuracy of intraoral scanning and photogrammetry-based acquisition methods for full-arch implant-supported rehabilitations involving four and six implants. Methods: An acrylic edentulous mandible was used to simulate the clinical setting. Implant positions were acquired 20 times per condition using five intraoral scanners with polyetheretherketone (PEEK) and titanium scan bodies, one photogrammetry-capable intraoral scanner, and three dedicated photogrammetry systems. Implant replicas were generated and analyzed using reverse-engineering software. Linear (µm) and angular (°) discrepancies were calculated to assess trueness and precision. Linear mixed-effects models were applied separately for linear and angular discrepancies, with impression method, implant configuration, and their interaction as fixed effects. Results: Mean linear trueness discrepancies ranged from 35.76 to 403.51 µm. Impression method significantly influenced linear and angular discrepancies (p < 0.001). Implant configuration had a significant effect, with higher discrepancies observed with six implants. No significant interaction was detected between impression method and implant configuration. Most photogrammetry-based systems showed lower discrepancies than the intraoral scanners, although substantial device-specific variability was observed. No consistent trend favoring PEEK or titanium scan bodies was observed. Conclusions: Impression method and implant configuration significantly influenced impression accuracy. Photogrammetry-based systems generally showed lower discrepancies, although device-specific performance should be considered when interpreting accuracy. Six-implant configurations, which involved a greater scanning span, were associated with lower accuracy. Further clinical studies are needed to determine whether these differences are clinically relevant.
Paradental cysts are inflammatory lesions that typically occur associated with the mandibular third molar, posing a challenge in the differential diagnosis with other odontogenic cysts. This paper describes the diagnostic and therapeutic management of a paradental cyst that was initially considered a dentigerous cyst based on its pericoronal location and radiological appearance as a well-defined unilocular radiolucency associated with an impacted tooth. A 64-year-old male patient presented with pain in the right mandibular region. Panoramic radiography and cone-beam computed tomography revealed a well-defined unilocular lesion associated with an impacted mandibular third molar, extending towards the mandibular second molar. Surgical treatment included complete enucleation of the lesion and extraction of both teeth. Histopathological analysis showed a non-keratinized stratified epithelial lining with chronic inflammatory cell infiltrate; together with the clinical and radiological findings, this allowed the definitive diagnosis of a paradental cyst. The postoperative course was uneventful, and a follow-up radiograph obtained at nine months showed early signs of ossification of the residual cavity.
Objectives: This systematic review compares the clinical efficacy and radiographic outcomes of membrane-based regeneration, bone grafting, and platelet concentrates in cavities resulting from apicoectomy, assessing healing rates and the quality of newly formed bone. Methods: Following PRISMA 2020 guidelines, a literature search was performed in PubMed, Cochrane Library, ScienceDirect, Wiley, and Scopus databases for articles published between January 2000 and December 2025. Eligibility criteria were defined using the PICOS framework, and included studies were evaluated based on clinical and radiographic parameters with a minimum follow-up of six months. Results: Eighteen clinical studies were included. Findings were heterogeneous and predominantly of low to very low certainty. Although some studies suggested potential benefits of regenerative adjuncts in complex defects, such as through-and-through and apicomarginal lesions, a substantial proportion found no statistically significant advantage over conventional apical surgery. Smaller lesions (<3 mm) generally responded favorably to conventional surgery, whereas larger defects may benefit from adjunctive regenerative approaches in selected clinical situations. Conclusions: Overall, the available evidence suggests a potential benefit of combining physical support (biomaterials) and biological stimulation (platelet-rich fibrin) in regenerative apical surgery. However, findings remain heterogeneous and should be interpreted cautiously. Technique selection should consider defect morphology, lesion characteristics, and available resources. Further standardized and methodologically robust studies are required to strengthen the current evidence base.
Objectives: To evaluate the within-session repeatability of surface electromyographic func- tional indices obtained with the Teethan® wireless system and to determine the influence of body posture during maximum voluntary clenching. Methods: Thirty-one healthy dentate participants with no self-reported temporomandibular pain or dysfunction were enrolled in a repeated-measures study. Bilateral electromyographic recordings of the masseter and anterior temporalis muscles were obtained with the Teethan® system in sitting, standing, and supine postures. For each posture, three consecutive clenching trials were recorded without removing the electrodes. Descriptive statistics, intraclass correla- tion coefficients, repeated-measures analysis of variance, Bonferroni-adjusted comparisons, and Pearson correlation coefficients were calculated as supplementary association analyses. Results: No significant differences among body postures were observed for most indices, except for the masseter symmetry index, which showed higher values in sitting than in supine posture. Because postures were assessed in a fixed order, this difference should be interpreted cautiously. Most pairwise correlations between repeated trials were moderate to strong. Overall intraclass correlation coefficient values for average measures ranged from 92.2% to 96.8%, indicating excellent reliability. Single-measure reliability ranged from 79.8% to 91.0%, the within-subject coefficient of variation from 9.3% to 23.1%, and Bland– Altman analysis showed negligible systematic bias. Conclusions: Within the limitations of this study, the evaluated indices demonstrated high within-session repeatability and were minimally influenced by body posture during maximum voluntary clenching in healthy adults.
