The aim of this study was to determine the prognosis and factors influencing the survival of these patients.Material and methods: Using the SEER database, we retrieved clinical data of patients with malignant tumors of dental origin between 1975 and 2020. They include 3 histological groups: metastatic ameloblastoma (METAM), malignant odontogenic tumors (MOT, including odontogenic carcinoma, odontogenic sarcoma, primary intraosseous carcinoma, and ameloblastic carcinoma) and ameloblastic fibrosarcoma (AFS).Results: On 251 patients, we observed no significant difference in disease-specific survival (DSS) between the three histological groups, with 5-year DSS of 77.4 % (59.9 - 100), 84.0 % (78.7 - 89.7) and 71.1 % (50.7 - 99.7) for METAM, MOT and AFS respectively (p = 0.460). In the MOT group, using a multivariate analysis, surgical treatment appeared to be a protective factor for DSS (HR = 0.483 [0.243 - 0.960], p = 0.038) after taking into account the potential confounding factors mentioned above. No variable significantly influenced DSS in the METAM and AFS group in univariate analysis.Discussion: We found no difference in specific survival between the three histological groups. Although metastatic ameloblastoma was reclassified as a benign tumor by the WHO in 2017, the vital risk for patients remains consequent, and statistically similar to malignant odontogenic tumors.","PeriodicalId":56038,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":" ","pages":"102179"},"PeriodicalIF":2.2,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142775122","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 evaluates stress distribution on bone, implants, abutments, gingiva, and prostheses based on posterior implant angulation, using both standard and angled neck implants. Additionally, angled neck implants were used alongside standard implants.Methods: To evaluate the biomechanical stress and displacement behavior of implants placed at 15°, 30°, 45°, and 30° neck-angled in the interforaminal region of using the All-on-four technique, under a 200 N masticatory force on bone, implant, abutment, and prosthesis, using the FEA method with a nonlinear solver.Results: The stress values measured in the neck region of the angled implant and abutment placed in the distal region were highest in model IV (305 and 420 MPa), followed model III (282 and 359 MPa), model II (192 and 337 MPa) and lowest in model I (177 and 225 MPa), respectively. The mean elemental von Mises stress in the mandibular bone region where the implant was placed was highest in model I (56 MPa) and lowest in model III (40.4 MPa).Conclusion: As the angle of insertion of the implant into the bone increases, the biomechanical stress value on the implant and abutment also increases. Among the models, the lowest von Mises stress values on the implant and abutment were measured in model I and model II. Models with low stress values can be recommended for patients with clinical conditions and biomechanical risk factors.","PeriodicalId":56038,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":" ","pages":"102157"},"PeriodicalIF":2.2,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756022","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}

A multivariate Cox proportional hazards model analysis was performed to evaluate factors affecting survival outcomes.Results: Males were slightly predominant (58.1 %). The most common subsite was an oral tongue (48.5 %), followed by an alveolar ridge (18.5 %). Advanced stages (III-IV) presented most at 88.5 %. The majority of the patients (52.3 %) received surgery and chemoradiotherapy, followed by surgery and radiotherapy (36.9 %), and surgery alone (10.8 %). The five-year overall survival (OS), disease-specific survival, and disease-free survival were 28.8 %, 44.0 %, and 46.3 %, respectively. Age > 45, ECOG performance status 2, and positive surgical margin status were found to be independent predictors for decreased OS (aHR 1.74, 95 % CI 1.01-3.00, aHR 2.64, 95 % CI 1.22-5.68, and aHR 1.76, 95 % CI 1.18-2.63, respectively).Conclusions: Survival outcomes of OSCC in the study remain poor compared to other studies. The high prevalence of locally advanced stage presentation and inadequate surgical margin are the main problems. Public awareness, cancer screening programs, and intraoperative specimen-driven evaluation might help obtain adequate surgical margins and improve survival outcomes.","PeriodicalId":56038,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":" ","pages":"102166"},"PeriodicalIF":2.2,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142741540","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}

Epidemiological, radiological, and pathological data, risk factors, details of surgical treatment, and surgical/oncological outcomes were analyzed.Results: 35 patients with recurrent pleomorphic adenoma were recruited, 19 were women (54.3 %) with the parotid gland being the most affected site in 74.3 % followed by the submandibular gland in 20 %. Only 11 patients (31.4 %) underwent surgery for the primary tumor in our center, and of interest that 48.6 % of the total cohort underwent simple enucleation for their primary tumors. The interval between resection and recurrence was shortened with frequent recurrences. Again, 71.4 % of facial nerve injuries had a history of simple enucleation for their primaries. 3 cases of Carcinoma ex pleomorphic adenoma were reported, representing 1.4 % of the patients with parotid pleomorphic adenoma in the study period, and was associated with young age and long-standing recurrence.Conclusions: Surgery is the cornerstone treatment for both primary and recurrent pleomorphic adenoma. Inadequate primary surgery, long-standing lesions, multiplicity, and fragmentation may be associated with facial nerve injury. Reconstructive flaps may be needed to cover the large resultant defects. Surgery for pleomorphic adenoma should be done by adequately trained surgeons. Radiation as an adjuvant treatment needs to be used frequently, especially through a multidisciplinary approach. Carcinoma ex pleomorphic adenoma, being rare, is demanding in its management with a poor prognosis.","PeriodicalId":56038,"journal":{"name":"Journal of Stomatology Oral and Maxillofacial Surgery","volume":" ","pages":"102164"},"PeriodicalIF":2.2,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142717852","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}

Their symptoms were well controlled and the inflammatory indicators were decreased. During the mandible remolding, the osteolytic destruction in one patient migrated from the left mandible to the right, while DSO lesion migrated from the left mandibular body to the ramus and condyle in the other.Conclusion: DSO presented as migratory lesions in mandible after biological inhibitors therapy, while the periosteal reaction wasn't conformed to the osteolytic focus.

This situation generates concern for both the clinician and the patient. The purpose of this article is to identify ocular complications related to lower dental nerve block, analyzing signs, symptoms, gender, age, type of procedure, and duration of complications.Methods: In September 2023, we conducted a systematic review using various databases, such as PubMed, ScienceDirect, and Google Scholar, using relevant search terms. There were no restrictions on the date or language of the articles.Results: We identified 39 articles that met the selection criteria, covering an analysis of 45 cases. Complications showed a higher incidence in women, with 65.11 %, compared to 34.8 % in men. The most frequent ocular complications reported were diplopia (44 %), amaurosis (28 %) and eyelid ptosis (17.77 %).Conclusions: Ocular complications related to lower tooth nerve block are rare, but they can occur. A higher incidence is observed in women than in men, and there is no specific age that predominates in its appearance. Diplopia is the most common ocular complication, followed by amaurosis, eyelid ptosis, and blurred vision.
