In the axial section, the widest diameter of the NPC was measured and categorized based on imaging; normal NPC: (≤6 mm), enlarged NPC (>6 mm and ≤10 mm) and pathology-suspected group, (>10 mm), radiographically suggestive of nasopalatine canal cysts (NPCC). This grouping was purely based on imaging findings and does not equate to a confirmed diagnosis of NPCC, as no histopathological verification was performed.Results: 70 patients were included in the normal NPC group, 70 patients in the enlarged NPC group, and 20 patients in the pathology-suspected NPC group. No statistically significant relationship was found between age, sex, and dentition status across the normal, enlarged, and pathology-suspected groups. The vertical diameter of the IOF was significantly higher in the enlarged and pathology-suspected groups. For the FPM, although an increasing tendency was observed bilaterally, statistically significant increases in A-P and M-L diameters were found only on the right side. (p < 0.001).Conclusion: The results indicated that NPC enlargement is associated with increased dimensions of the IOF and FPM. Based on these findings, it can be suggested that individuals with a wider NPC, especially when accompanied by enlarged IOF and FPM, may have a higher radiographic risk profile for NPCC development.","PeriodicalId":56038,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":" ","pages":"102492"},"PeriodicalIF":2.2,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photobiomodulation (PBM) has emerged as a potential intervention to mitigate radiation-induced tissue damage. This study aimed to evaluate the effects of PBM on the parotid glands of Wistar rats subjected to ionizing radiation.Methods: Forty-two male Wistar rats (7-8 weeks old) were randomly assigned to seven groups (n = 6). G1: control; G2: radiotherapy only (20 Gy); G3: PBM only; G4-G7: PBM combined with radiotherapy. PBM was applied using the Laser Duo (MMOptics®) with 660 nm and/or 808 nm wavelengths, varying in dose and number of application points. The histological analysis focused on preserving the acinar area. Receiver operating characteristic (ROC) curve analysis was used to determine the threshold for preserved acinar architecture.Results: The group receiving combined PBM (660 nm + 808 nm, 54 J per gland; G5) demonstrated the highest preservation of acinar morphology, closely resembling the control. Groups receiving isolated red or infrared wavelengths (G4, G6) showed moderate protection. The lowest dose group (G7, 1.8 J) was ineffective.Conclusion: PBM significantly reduced RT-induced damage to the parotid glands in a dose-dependent manner. The red laser protocol at 27 J per gland showed the highest level of tissue preservation. These findings support the potential of PBM as a protective adjunct during radiation therapy (RT) and justify further studies to standardize optimal clinical parameters.","PeriodicalId":56038,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":" ","pages":"102485"},"PeriodicalIF":2.2,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144565469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate GPC anatomy in cleft lip and palate (CLP) patients using cone-beam computed tomography (CBCT) to support safer clinical interventions.Methods: Anatomical comparisons were performed between CLP patients and non-cleft controls using CBCT scans. Evaluated parameters included greater palatine foramen (GPF) width, linear distances from the GPF to surrounding anatomical landmarks (such as the pterygoid canal (PC), infraorbital foramen (IOF), occlusal plane, and midsagittal plane), angular measurements of the GPC (transverse and vertical angles, and the angle toward the pterygopalatine fossa), the number of lesser palatine foramina, and the position of the GPF relative to maxillary molars. Subgroup analyses were conducted within the CLP group based on cleft type (unilateral cleft side, non-cleft side, bilateral), age (≤16 vs. >16 years), and sex.Results: The study included 118 patients with CLP and 118 healthy controls. CLP patients demonstrated significantly longer PC-IOF distances and significantly shorter GPF-PC distances compared to controls (P < 0.001 for both). In addition, both transverse and vertical GPC angles were significantly greater in the CLP group (P < 0.001). Subgroup analysis revealed that bilateral CLP patients had lower PC-IOF distances and smaller vertical GPC angles compared to those with unilateral clefts (p = 0.018, p = 0.011).Conclusions: CLP patients demonstrate anatomical variations in GPC morphology that may affect anesthetic access and surgical safety. These findings highlight the value of individualized CBCT-based planning in maxillary procedures.","PeriodicalId":56038,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":" ","pages":"102487"},"PeriodicalIF":2.2,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144568139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The predictor variables were categorized as preoperative, operative, or postoperative variables. The outcomes of interest were oral competence, wound dehiscence, flap necrosis, reoperation, and tumour recurrence. Appropriate statistics were computed using a cut-off value of 0.05.Results: The study included six patients with a mean age of 62.5 ± 10.3 years and a mean body mass index (BMI) of 29.93 ± 1.7 kg/m2. The average tumour size was 4.7 ± 0.8 cm. All patients were male smokers who smoked more than twenty cigarettes per day. Two operations were complicated with partial flap necrosis (33.3 %), and three patients (50 %) experienced minimal drooling, which improved over time. Only BMI and tumor grade showed a significant relationship with the incidence of postoperative complications (P = 0.009, 0.006, respectively). A good aesthetic outcome was observed in all cases.Conclusion: Based on this small cohort, the bilateral inferiorly based nasolabial flap technique is a safe and easily harvested option that provides acceptable functional and cosmetic outcomes, with minimal donor site morbidity, for the reconstruction of large lower lip defects following tumour resection. It could be an alternative to other longer or more aggressive treatment methods, such as microsurgery, for elderly patients or those with medical comorbidities.","PeriodicalId":56038,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":" ","pages":"102488"},"PeriodicalIF":2.2,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144568138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three-dimensional finite element analysis was used to evaluate the amount and distribution of stress around implants under different vertical and oblique loading conditions.Results: The maximum stress distribution in the implant abutment contact area in the IFC was 565.44 MPa and screw peak stress values were determined to be 518.96 MPa in the transition zone for MTC. MTC caused the lowest bone stress, although there was no significant difference between the connection systems in terms of material type.

The biomaterials are available in particles, gel, blocks, and cement pastes. The aim of this study is to evaluate the influence of hyaluronic acid gel enriched with amino acids on bone healing in a rabbit artificial bone defect.Methods: Six rabbits were used in this study, for each tibia, a 3 mm bilateral non critical-size circular defect was produced. The drilling was performed on cortical bone with no invasion of the medullary component. The bone defect was filled with Hyaluronic acid enriched with amino acid while the second defect was used as empty control. The HA filling enriched with amino acid was positioned into the bone defect with no pushing into the medullary space. No covering membranes were applied on top of the bone defect. The rabbits were euthanized by an intravenous pentobarbital overdose after 4 weeks and a total of 36 biopsies (6 for each group) were retrieved. The samples were processed to obtain histological sections.Results: In the control sites, newly formed tissues in the defects were characterized by 25 ± 3 % of lamellar bone, 25 ± 1 % of woven bone and 50 ± 3 % of medullary spaces. The osteoblast count in the bone defect was 15±3 and 1 ± 2 vessel. In the test sites the morphometry findings were characterized by 28 ± 3 % of lamellar bone, 73 ± 1 % of woven bone and 0 % of marrow spaces. The osteoblast and vessel count was 87±3 and 6 ± 2 vessels per field. Statistical differences were found for the number of osteoblasts, vessels and new bone.

This study presents a 69-year-old male with left mandibular GSCC, treated with segmental mandibulectomy and selective neck dissection, followed by reconstruction using a deep circumflex iliac artery (DCIA) vascularized iliac crest flap with double musculocutaneous skin islands. Preoperative virtual surgical planning and 3D-printed surgical guides facilitated precise osteotomy and optimal flap design. The harvested iliac flap provided robust vascularization, adequate bone volume for mandibular continuity, and dual skin paddles for intraoral and extraoral soft tissue coverage. Postoperative evaluation demonstrated excellent functional and aesthetic outcomes, with stable osseous integration, viable soft tissue reconstruction, and no recurrence. This case underscores the versatility of the DCIA iliac crest flap in restoring both mandibular structure and oral function, highlighting advancements in microvascular surgery, 3D planning, and patient-specific reconstruction strategies. This case highlights the potential of the DCIA flap in addressing complex maxillofacial defects.
