Abstract
Since its introduction in 1968, the TNM (tumor, node, metastasis) classification established by the International Union Against Cancer has provided a consistent framework for staging of oral squamous cell carcinoma (OSCC). The introduction of the 8th edition in 2017 brought about significant modifications, encompassing the integration of depth of invasion (DOI) and extranodal extension (ENE) into the T and N classifications. Further, the UICC the criteria for the T3 and T4a categories were amended in 2020. This study aimed to evaluate the impact of reclassification on staging and, subsequently, the survival of patients with OSCC. Primary OSCCs from 391 patients were classified according to the 7th and revised 8th UICC editions (2020). Stage migration was assessed, and stage-specific progression-free survival (PFS) and overall survival (OS) were evaluated using the Kaplan-Meier method. The log-rank test was used to compare the different stages. Cox-proportional hazard modeling was used to compare the two editions. Incorporating the DOI into the T classification resulted in an upstaging of 77 patients, constituting 19.69% of the cohort. In addition, 49 (12.53%) patients experienced an upstaging when considering ENE in the N classification. Consequently, 103 patients underwent upstaging in UICC staging, accounting for 21.74% of cases. Upstaging mainly occurred from stage III to IVA (26.92%) and from stage IVA to IVB (31.78%). Upon comparing the categories in survival analysis, significant differences in OS and PFS were especially observed between stage IVB and lower stages. When examining the hazard ratios, it became evident that UICC 8 stage IVB is burdened by a 5.59-fold greater risk of disease progression than stage I. Furthermore, UICC 8 stage IVB exhibits a 3.83 times higher likelihood of death than stage I disease. We demonstrated significant stage migration from the 7th to the revised 8th UICC edition. Overall, incorporating DOI and ENE into the T and N classifications represents a substantial clinical advancement, leading to a more accurate staging of OSCC patients. Both staging systems exhibited statistically significant discrimination between stages; however, the 8th UICC edition allowed for a more precise categorization of patients based on their prognosis and led to enhanced hazard discrimination, particularly within higher stages.

Abstract
Background To evaluate the prospects for dental implants in people with diabetes. Materials and Methods Thirty patients in all were enrolled. The age range was from 40 to 60. Out of 30, 8 men and 22 women were present. HbA1c values were calculated. HbA1c levels and the ratio of problems to implant numbers were shown to be correlated. Data were gathered. Software called SPSS was used to analyses the results. Results Thirty patients in all were enrolled. In follow-up cases, the stratification levels of HbA1c were investigated. The implant failure rate in 8.0-8.9 was 90.91%, with 2 implants failing. The survival rate in 11.0-11.9 was 75%. Others had a 100% success rate. Conclusion Patients with diabetes have higher implant survival rates and fewer problems.

Abstract
Background One of the most common types of malignancies affecting the head and neck region is oral squamous cell carcinoma (OSCC). Little less is known about the role of myofibroblasts in the pathogenetic process of OSCC. Hence, we assessed the involvement of myofibroblasts in the invasive process of OSCC using α-SMA (α-smooth muscle actin) antibody. Materials and Methods Four study groups in total were organized as follows: 40 cases each of well-differentiated OSCC (WDOSCC), moderately differentiated OSCC (MDOSCC), poorly differentiated OSCC (PDOSCC), and controls make up Group 1, Group 2, Group 3, and Group 4, respectively. The percentage of α-SMA immunopositive cells and staining intensity (A) multiplied together to determine the final staining score (B). The final staining index was produced by multiplying staining intensity (A) by the proportion of immunopositive cells that were stained with α-SMA (B) (FSI). Score Zero was graded as Index Zero by FSI while scores One and Two received an Index Low rating, scores Three and Four an Index Moderate rating, and scores Six and Nine an Index High rating. Results Significantly higher expression of myofibroblast was observed in OSCC group in comparison with the control group. However; no significant difference in myofibroblast expression was observed while comparing different grades of OSCC. Conclusion We recommend using myofibroblasts as a stromal marker to track the severity and development of OSCC.
