The aim of our study was to assess the nutritional and quality of life of patient-reported outcomes among patients who have undergone laser resection of tongue cancer.Materials and methods: A cross-sectional study was undertaken of patients treated with KTP laser resection of T1/T2 tongue squamous cell carcinoma (SCC) between 2011-2019. University of Washington Quality of life 4 questionnaire (UW-QOL) and the abridged scored patient-generated subjective global assessment (AB PG-SGA) were used. Scores were correlated to analyse the QOL and nutritional status.Results: 20 patients participated and were categorised into three groups based on AB PG-SGA score. The physical and social-emotional QOL scores were higher for patients who had a better nutritional status. There was a linear negative correlation between the AB PG-SGA score, physical and social-emotional domains of the QOL. No association was found between histopathological differentiation, neck dissection surgeries and the AB PG-SGA score.Conclusions: The use of the KTP laser to excise tongue T1 and T2 SCC yields acceptable results in terms of QOL and patient-reported nutritional outcomes. There is a significant trend identifying that as a patient's nutritional status improves quality of life is enhanced and vice versa. The QOL and the nutritional status of patients were not affected by the different histopathological grades of SCC or whether they had undergone a neck dissection or not.","PeriodicalId":47251,"journal":{"name":"Oral and Maxillofacial Surgery-Heidelberg","volume":"29 1","pages":"41"},"PeriodicalIF":1.7,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143025311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is still unclear which form provides better bone formation and is the best to use clinically. This network meta-analysis aimed to thoroughly evaluate the available literature on the ability of different forms of the autogenous tooth graft to promote bone regeneration, in order to explore if any specific type or method of processing would result in better overall outcomes.Methods: MEDLINE/PubMed, Cochrane library, and Scopus databases were searched, to find randomized clinical trials, published up to November 29, 2023, which compared two forms of autogenous tooth graft or any form of this material with other bone grafts or with empty sockets and reported the percentage of bone formation in the grafted sites.Results: Of 1129 articles found, nine were included. The outcomes of this meta-analysis indicated that demineralized dentin, demineralized root with BMP-2 and undemineralized tooth all showed significantly higher bone formation, compared to xenograft; Mean difference (MD) = 23.25, 95% Confidence interval (CI) = 7.42 to 39.08, MD = 17.09, 95% CI = 4.03 to 30.15, and MD = 12.40, 95% CI = 5.64 to 19.16, respectively. Following the GRADE system, the level of evidence was judged to be low/very low.Conclusion: Choosing the undemineralized tooth could be a better option than other forms of this material, considering the complexity, time, and cost of the other forms of autogenous tooth graft. Nevertheless, future investigations with more direct comparisons are highly needed, considering the small number of included studies and the low level of evidence obtained from this meta-analysis.","PeriodicalId":47251,"journal":{"name":"Oral and Maxillofacial Surgery-Heidelberg","volume":"29 1","pages":"40"},"PeriodicalIF":1.7,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143013983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concerning the lower lip, exposure to UV radiation is the main etiological factor associated with the development of epidermoid carcinomas and actinic cheilitis. According to the hierarchical model theory, cancer development is driven by populations of cancer stem cells. In this context, this study aimed to compare the expression of octamer-binding transcription factor 4 (OCT4) and CD44 in 40 lower lip epidermoid carcinoma (LLEC) and 40 actinic cheilitis (AC) cases.Methods: OCT4 and CD44 expressions were assessed semi-quantitatively according to the percentage of positive epithelial cells (PP) and intensity of expression (IE), resulting in a total immunolabeling score (PIT).Results: No statistically significant differences were detected between OCT4 and CD44 immunoexpression and clinicopathological parameters, except for lymph node metastasis, in which a decrease in CD44 expression in the core tumor of cases with lymph node metastasis was observed. Furthermore, decreased CD44 expression was observed in LLEC cases when compared to AC cases.Conclusions: The findings reported herein suggest a higher participation of CD44 in early carcinogenesis stages. In addition, the imbalance between OCT4 and CD44 immunoexpressions suggests the presence of different neoplastic cell subpopulations.","PeriodicalId":47251,"journal":{"name":"Oral and Maxillofacial Surgery-Heidelberg","volume":"29 1","pages":"36"},"PeriodicalIF":1.7,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143013992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study defines the impact of BMMSCs and their derived exosomes on proliferation, apoptosis and oxidative stress (OS) levels of CP-induced parotid salivary gland damage.Methods: BMMSCs were isolated from the tibia of four white albino rats and further characterized by flowcytometric analysis. BMMSCs-derived exosomes were harvested and underwent characterization using transmission electron microscopy (TEM), western blot analysis and BCA assay. Fifty-six healthy white albino male rats weighting from 200 to 250 g were allocated into 4 groups (n = 14); Group I, rats received phosphate buffered saline (PBS), group II, rats were intraperitoneally injected with CP, group III& IV received CP and after 3 days they were intravenously injected with either BMMSCs (group III) or BMMSCs-exosomes (group IV). Histological, and immunohistochemical studies using proliferating cell nuclear antigen (PCNA) were done after 7 and 14 days. The OS was measured using malondialdehyde (MDA) and apoptosis was measured by annexin V-FITC/PI.Results: BMMSCs and exosomes treated groups showed better histological features approximating the normal architecture of the control group. The percentage of PCNA positively stained cells were significantly higher in the exosomes treated group in comparison to all other groups. MDA assay test revealed that the exosomes were able to reduce the OS when compared to the cell-based therapy using BMMSCs. Annexin V revealed that BMMSCs-exosomes significantly reduced the percentage of apoptotic cells compared to other treated groups.Conclusions: BMMSCs-exosomes could improve the CP-induced cytotoxicity in rats' parotid salivary gland.","PeriodicalId":47251,"journal":{"name":"Oral and Maxillofacial Surgery-Heidelberg","volume":"29 1","pages":"39"},"PeriodicalIF":1.7,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11742274/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143013971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smartphone technology and AR application (app)-based intraoral tracking were used for dCAIS. The app allowed real-time visualization of implant planning, superimposition of three-dimensional models, and alignment of surgical instruments. Forty dental students performed four pilot drillings each; two were performed freehand, whereas two were performed using the app. The angulation and position of the prepared implant bed preparation were statistically analyzed.Results: Implant angulation was significantly better in the AR-guided group than in the unguided group; however, no significant difference was observed in the implant position.Conclusions: Smartphone-based AR techniques for dCAIS are easily accessible in dental implantology.

Some centres have reported that non-smoking non-drinking (NSND) patients represent a significant and increasing proportion of OSCC cases with reports of poorer outcomes. Demographic characteristics are variably reported for this group and carcinogenesis is not fully understood. We present the largest cohort study to date in this subject area and sought to better understand demographics and survival.Methods: We interrogated 541 OSCC patients by retrospective analysis to assess risk factor status, disease characteristics and survival. Patients were categorised according to smoking and alcohol exposure with non-smoker (NS) status defined as less than five cigarettes per week with no history of use greater than this. Non-drinker (ND) status was defined as less than three standard drinks per week with no history of alcohol consumption greater than this. Those both NS and ND were categorised as NSND. Subsite, tumour stage and treatment were recorded along with evidence of cervical nodal and distant metastasis.Results: These patients were more likely to be female, older and present with early-stage disease. Tumour site was tongue, maxillary alveolus and buccal mucosa, at variance with the smoker drinker groups.Conclusion: NSNDs comprise a significant proportion our OSCC population. These patients were more likely to be female, older and present with early-stage disease. Tumour site was tongue, maxillary alveolus and buccal mucosa, at variance with the smoker drinker groups. Thus, NSNDs are a clinically distinct and significant group in oral cavity cancer management.","PeriodicalId":47251,"journal":{"name":"Oral and Maxillofacial Surgery-Heidelberg","volume":"29 1","pages":"35"},"PeriodicalIF":1.7,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143013973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
