Understanding the Interaction of Röntgen Radiation Employed in Computed Tomography/Cone Beam Computed Tomography Investigations of the Oral Cavity by Means of Surface-Enhanced Raman Spectroscopy Analysis of Saliva.

The use of Raman spectroscopy, particularly surface-enhanced Raman spectroscopy (SERS), offers a powerful tool for analyzing biochemical changes in biofluids. This study aims to assess the modifications occurring in saliva collected from patients before and after exposure to cone beam computed tomography (CBCT) and computed tomography (CT) imaging. SERS analysis revealed significantly amplified spectra in post-imaging samples compared to pre-imaging samples, with pronounced intensification of thiocyanate and opiorphin bands, which, together with proteins, dominated the spectra.

Developing New Diagnostic Tools Based on SERS Analysis of Filtered Salivary Samples for Oral Cancer Detection.

Cancer still represents one of the biggest challenges in current medical practice. Among different types of cancer, oral cancer has a huge impact on patients due to its great visibility, which is more likely to create social stigma and increased anxiety. New early diagnose methods are still needed to improve treatment efficiency and patients' life quality.

High-Frequency Ultrasound Assessment of Skin and Oral Mucosa in Metabolic Syndrome Patients-A Cross-Sectional Study.

Background: Exogenous factors (such as sun exposure, smoking habits, and diet) and endogenous (inflammatory status, general diseases) have a direct influence on skin and soft tissue characteristics. The study's objective was to assess the impact of metabolic syndrome (MS) on characteristics of skin layers in sun-exposed and non-exposed maxillofacial tissues evaluated by high-frequency ultrasound (HFU), as a potential diagnosis and monitoring tool for the aging process.

Material And Methods: The present study included 102 subjects (24 with MS; 78 without MS).

The value of ultrasound diagnosis in the multidisciplinary approach of cutaneous tumours. Case report.

We report the case of a senior patient, presenting with two cutaneous tumours in which the clinical and dermoscopic examination pointed towards a basal cell carcinoma. Ultrasound revealed highly vascularised tumours and elastography showed increased rigidity. Histological examination of both lesions following complete resection was consistent with squamous cell carcinomas.

Application of Fuzzy Logic in Oral Cancer Risk Assessment.

Background: The mapping of the malignization mechanism is still incomplete, but oxidative stress is strongly correlated to carcinogenesis. In our research, using fuzzy logic, we aimed to estimate the oxidative stress related-cancerization risk of the oral potentially malignant disorders.

Methods: Serum from 16 patients diagnosed (clinical and histopathological) with oral potentially malignant disorders (Dept.

Subantral bone grafts, a comparative study of the degree of resorption of alloplastic versus autologous grafts.

The placement of dental implants in the posterior region of the maxillary may pose some difficulties caused by the quality and particularly, the quantity of the subantral bone reserve, which are overcome by subantral bone augmentation. The current study performs a comparative evaluation of the quality and especially, of the stability of alloplastic and autologous materials used for subantral bone augmentation. This study included 21 patients who underwent subantral bone augmentation with alloplastic and autologous material.

Subantral Augmentation with a 1/1 Alloplastic and Autologous Material Mixture. Histological Characteristics and Dimensional Stability of the Newly Formed Bone.

Background And Aim: The maxillary sinus augmentation procedure is the most frequent method used to prepare the posterior maxillary area, with bone deficit, for the placement of dental implants. For this purpose, several types of materials have been used as bone grafts, each of these materials having a number of advantages and disadvantages. The present study is aimed at evaluating the histological and volumetric properties of an alloplastic and autologous material mixture.

Efficiency of Empirically Administered Antibiotics in Patients with Cervical Infections of Odontogenic Origin.

Background And Aims: Odontogenic infections are among the main types of disorders located in the cephalic extremity. The aim of this study was to determine the efficiency of empirically administered antibiotics on the bacterial strains identified at the infection sites.

Patients And Method: The study included 10 randomly selected patients with odontogenic cervical soft tissue infections, who received antibiotic treatment prescribed by the family doctor or the dentist.
