Background and Objectives: Dental restorations can be composed of various materials, including amalgams and methacrylate-based resins. The health risks associated with the components of the restorative materials have always been a concern, even more so with the ageing of the restorations. As the micronucleus (MN) test is a standard, accessible, and minimally invasive technique for studying the genotoxic effect of clastogenic chemicals on oral mucosal cells, the current study was conducted to determine the frequency and morphological properties of MN in the exfoliated oral mucosal cells. Materials and Methods: A total of 115 aged composite and amalgam restorations were included in this study. Epithelial cells were collected from the gingival tissue adjacent to the restorations of each patient and stained with a hematoxylin–eosin (HE) stain. After evaluation of the slides, the results were subjected to statistical analysis using Chi-square tests. The level of significance was set at 0.05. Results: The mean number of MN was significantly lower for composite restorations compared to amalgam restorations. There were no statistically significant differences between composite restorations aged 1–5 years, 5–10 years, over 10 years, and amalgam restorations aged over 10 years in the location (p = 0.11), staining (p = 0.11), or morphological characteristics (p = 0.18) of the MN. Conclusions: Despite the main limitation of this study, the lack of a control group, our results suggest that long-term exposure to restorative fillings and the ageing of these materials can cause DNA damage locally in the adjacent sites of oral cavity.

Cervical necrotizing fasciitis is a very rare complication of a bacterial infection that can have a dental cause. This type of infection typically affects fascial plane, which has a poor blood supply and can affect soft tissue and cervical fascia and can spread quickly causing infection of mediastinum. Initially, in the first stage, the overlying tissues are unaffected, and this can delay diagnosis and surgical intervention. Incidence in children is extremely rare and can be frequently associated with various other general pathologies that decrease the immune system response. We present a case of a young 12-year-old boy diagnosed with this type of infection in the head and neck as a complication of a second inferior molar pericoronitis. The treatment and the management of the case was difficult not only due to the presence of the infection but also because of the prolonged intubation.

Background: Head and neck cutaneous squamous cell carcinoma (HNcSCC) presents intersecting oncologic, functional, and reconstructive challenges. Although numerous clinicopathologic factors have been associated with recurrence, metastasis, and survival, their relationship with reconstructive complexity and patient-centered outcomes remains insufficiently studied. This review aimed to examine how established oncologic risk factors might inform reconstructive planning while distinguishing measured reconstructive evidence from hypothesis-generating clinical inferences. Methods: A structured PubMed/MEDLINE search conducted through 15 July 2026 was used to identify the literature addressing clinicopathologic prognostic factors in HNcSCC. Twenty-nine prognostic publications were retained for structured charting. Additional reconstructive, functional, aesthetic, and patient-reported outcome sources were identified through reference-list screening and were used solely for narrative contextualization. Because no dedicated multi-database systematic search of reconstructive outcomes was performed, the article is presented as a structured narrative review and hypothesis-generating research framework rather than a systematic review of reconstructive evidence. Results: The prognostic literature reported associations between adverse oncologic outcomes and factors including tumor size and depth, perineural invasion, lymphovascular invasion, poor differentiation, immunosuppression, recurrent disease, positive margins, nodal involvement, and extranodal extension. However, most of these studies did not measure post-excision defect characteristics, reconstructive technique, wound complications, functional recovery, scar quality, aesthetic outcomes, or patient-reported outcomes. Direct reconstructive evidence was limited and predominantly derived from site-specific, mixed-histology, technical, or methodological publications. Consequently, clinicopathologic factors should be regarded as potential upstream variables for future investigation rather than validated predictors of reconstructive outcomes. Conclusions: Current evidence supports oncologic risk stratification more strongly than prediction of reconstructive difficulty or patient-centered outcomes in HNcSCC. Prospective studies should jointly measure patient, tumor, treatment-field, defect, reconstructive, functional, aesthetic, and patient-reported variables. The proposed framework is intended to guide such research and is not a validated clinical prediction model.
