Salivary miR-31-5p, miR-345-3p, and miR-424-3p Are Reliable Biomarkers in Patients with Oral Squamous Cell Carcinoma.

If not detected early, oral squamous cell carcinoma (OSCC) has very poor prognosis, emphasizing the need for reliable early diagnostics. Saliva is considered a promising surrogate biosample for OSCC detection, because it comes into contact with many cells of the tumor mass, providing a comprehensive sampling of tumor-specific biomolecules. Although several protein- and RNA-based salivary biomarkers have been proposed for the detection of OSCC, the results of the studies show large differences.

Salivary IL-6 mRNA is a Robust Biomarker in Oral Squamous Cell Carcinoma.

Salivary IL-6 mRNA was previously identified as a promising biomarker of oral squamous cell carcinoma (OSCC). We performed a multi-center investigation covering all geographic areas of Hungary. Saliva from 95 patients with OSCC and 80 controls, all Caucasian, were collected together with demographic and clinicopathological data.

Oral health-related quality of life after prosthetic rehabilitation: a longitudinal study with the OHIP questionnaire.

Background: Aspects of oral health related quality of life (OHRQoL) attracted an increased attention recently.

Objective: The aim of the study was to assess self-reported oral health related quality of life (OHRQoL) among patients requiring prosthetic rehabilitation and to determine the rate of improvement 1 month and 6-12 months after therapy. In addition, effect of age, gender, oral health indicators and denture types before treatment were assessed on OHRQoL as evaluated and reported by the patients.

Overlapping protective and destructive regulatory pathways in apical periodontitis.

Introduction: Protective and destructive immunoreactions take place simultaneously in apical periodontitis. However, the same reactions defending the periapical area from infection-derived damage may also result in host tissue injury.

Methods: The inflammatory reaction of the periapical tissues is self-limited.

Elevated tumor necrosis factor-alpha expression in periapical lesions infected by Epstein-Barr virus.

Introduction: In apical periodontitis, there is an intense inflammatory response to endodontopathogenic bacteria, an essential component of the pathogenic microbiota. The inflammation can be aggravated by herpesviruses acting as nonessential pathogens in periapical lesions. This study aimed to determine the levels of tumor necrosis factor-alpha (TNF-α) and transforming growth factor-beta (TGF-β) in periapical lesions in relation to local occurrence of Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), human herpesvirus 6 (HHV-6), and human herpesvirus 8 (HHV-8).

Oral cancer report from Northeastern Hungary.

In Hungary oral and pharyngeal cancers have been reported the fourth most common malignancy in males and the sixth for both sexes. The aim of the present study was to characterize oral squamous cell carcinoma (OSCC) patients in Northeastern Hungary. 119 randomly selected patients with OSCC were included in the study.

The influence of chronic apical periodontitis on oral and general health.

In healthy condition, the periodontal space between the root surface and the alveolar bone is relatively poor in cells. In case of root canal infection however, large number of immune-inflammatory cells infiltrate the periapical region of the affected teeth. A major issue is if and to what extent microbial and host cells contribute to lesion formation and whether the local inflammation may impair general health.

Oral and dental conditions of children with selective IgA deficiency.

Oral conditions in selective IgA deficiency in children have rarely been published. Our aims were to investigate their mucosal, periodontal, and cariological conditions in IgA deficient children matched with healthy controls and to draw data on their oral health in the North-East Region of Hungary. Thirty four patients and 111 healthy controls, matched by age and sex, were studied for oral mucosal disorders, periodontal disease, and caries.

Significance of oral Candida infections in children with cancer.

Candidiasis is common in children with cancer, particularly during periods of severe immunosuppression and neutropenia. Our aim was to study the microbiological changes in the oral cavity of children with newly diagnosed cancer. The study group consisted of 30 consecutive children and adolescents, 16 with acute lymphoblastic leukemia and 14 with solid tumors.

Expression of p16(INK4A), p53, and Rb proteins are independent from the presence of human papillomavirus genes in oral squamous cell carcinoma.

Background: The overexpression of p16(INK4A) and suppression of p53 and Rb proteins are key features of oncogenic transformation by human papillomaviruses (HPV) in anogenital cancers. HPV genomes are often detected in cancers of the oral cavity, but it is unclear whether HPV has a specific oncogenic role there.

Objectives: The objectives of the study were to investigate the expression of p53, Rb, and p16(INK4A) proteins and identify HPV infection and viral integration into the host genome.

p21WAF1/CIP1 expression is a marker of poor prognosis in oral squamous cell carcinoma.

Background: Previous research on the prognostic relevance of p21(WAF1/CIP1) in oral squamous cell carcinomas (OSCC) yielded inconclusive and contradictory data.

Objectives: To investigate the prognostic significance of p21(WAF1/CIP1) expression, its relationship to p53 accumulation, proliferation-associated proteins Ki-67 and cyclin D1 in relation to survival and clinicopathological features in OSCC.

Methods: Surgical specimens taken from 106 randomly selected patients were studied by immunohistochemistry.
