Imaging Retrospective Study Regarding the Variability of the Osseous Landmarks for IAN Block.

: The aim of this study is to identify the most accurate and consistent landmarks for determining the precise location of the mandibular foramen (MF) and the mandibular ramus, suggesting appropriate adjustments to anesthesia techniques based on these variations in order to improve the success rate of the inferior alveolar nerve (IAN) block. : CT scans of the mandibles from 100 patients were analyzed to measure the distance between the MF and various landmarks, including the sigmoid notch, gonion, posterior and anterior margins of the ramus, temporal crest, and the mandibular ramus height from the condyle to the gonion. The width of the mandibular ramus was also assessed, with correlations made to age and gender.

Systemic Immune-Inflammatory Index and Other Inflammatory Marker Variations in Oral Squamous Cell Carcinoma Management.

: With the greatest rate of morbidity and death, OSCC is one of the world's most critical public health problems. Being a complex pathology, the management process that includes diagnostic, surgical, and adjuvant treatments must as well take into account the involvement of the immune system. This study aims to evaluate various biomarkers such as neutrophils, lymphocytes, platelets, SII, and NLR in the different stages of OSCC treatment and in correlation with TNM stages, in order to observe the inflammatory response of the host.

CD34 and Ki-67 Immunoexpression in Periapical Granulomas: Implications for Angiogenesis and Cellular Proliferation.

Background/objectives: The main mechanism of the formation of granulation tissue is the progression of an infection from the tooth to the periapical bone. At this level, the immune system tries to localize and annihilate the microorganism's injury. Ki-67 is a protein directly associated with the cell proliferation rate, while CD34 is a biomarker involved in angiogenesis, and studies suggest that they both have a positive correlation with the intensity of the local inflammatory infiltrate.

Associated Bacterial Coinfections in COVID-19-Positive Patients.

: The aim of this study was to identify specific rhino- and oropharyngeal microbiological pathogens as well as associated comorbidities that favor SARS-CoV-2 infection and corelate them. : This prospective clinical study enrolled 61 patients (28 COVID-19-positive and 33 controls) who were tested for other comorbidities and co-existence of associated oral pathogenic microbiota. : A total of 247 bacterial isolates were identified in the bacterial cultures in both groups.
