Impact of and gene polymorphisms on prognosis and survival of patients with oral squamous cell carcinoma.

Despite significant efforts in developing new diagnostic and therapeutic modalities, oral squamous cell carcinomas (OSCCs) still exhibit a high recurrence rate, a low five-year survival rate, and an increasing prevalence. Toll-like receptors (TLRs), which initiate and perpetuate immune mechanisms upon activation, have been linked to immune surveillance and the antitumor immune response. The aim of this study was to investigate the association between the polymorphisms of the TLR7 rs3853839 and TLR9 rs187084 genes and OSCC risk, clinicopathological features, and survival.

Effects of apical periodontitis treatment on hyperglycaemia in diabetes: A prospective cohort study.

Aim: This prospective cohort study was undertaken to evaluate the success rate of root canal treatment (RCT) in type 2 diabetes mellitus (T2DM) patients with targeted level and unachieved targeted level of glycaemic control as well as the impact of RCT on the glucose blood level in T2DM patients.

Methodology: Patients needing RCT were divided into three groups: these without T2DM, that is, the control group (CG), those with targeted level of glycated haemoglobin HbA1c < 7% (TL A1c) and the third ones with unachieved targeted level (UTL A1c), that is, with HbA1c ≥ 7%. Before RCT, HbA1c and the periapical index (PAI) score were assessed, as well as 1 year later.

Vesicular Messages from Dental Biofilms for Neutrophils.

The encounter between dental biofilm and neutrophils in periodontitis remains elusive, although it apparently plays a crucial role in the periodontal pathology and constitutes a key topic of periodontology. Dental biofilm and neutrophils were isolated from orally healthy persons and patients with periodontitis. We investigated biofilm and its particle-shedding phenomenon with electron microscopy and nanoparticle tracking analysis (NTA); biofilm shedding-neutrophil interactions were examined ex vivo with epi-fluorescence microscopy.

Changes in pulp sensitivity across the menstrual cycle in healthy women and women with temporomandibular disorders.

Background: Menstrual cycle may contribute to experimental pain measures in healthy women and women with chronic pain.

Objectives: The present study aimed to investigate variation in pulp sensitivity across the menstrual cycle in healthy women and women with temporomandibular disorders (TMD) and to explore the effect of TMD pain and psychosocial variables on the pulp response.

Methods: This longitudinal study involved 47 regularly menstruating women aged 20-45, 24 healthy and 23 with diagnosed painful TMD.

Apolipoprotein ɛ4 Allele and Dental Occlusion Deficiency as Risk Factors for Alzheimer's Disease.

Compromised dentition has been suggested to pose a significant risk factor for dementia. It was mainly investigated through insufficient tooth number, disregarding contact between opposing teeth (dental occlusion). The ɛ4 allele of apolipoprotein (APOE4) is the primary genetic marker for the late onset of Alzheimer's disease (AD).

Pulp Sensitivity: Influence of Sex, Psychosocial Variables, COMT Gene, and Chronic Facial Pain.

Introduction: The purpose of this study was to evaluate the associations of variability in pulp sensitivity with sex, psychosocial variables, the gene that encodes for the enzyme catechol-O-methyltransferase (COMT), and chronic painful conditions (temporomandibular disorders [TMDs]).

Methods: The study was composed of 97 subjects (68 women and 29 men aged 20-44 years). The electric (electric pulp tester) and cold (refrigerant spray) stimuli were performed on mandibular lateral incisors.

Limited Jaw Movements and Somatization (But Not Pain) May Play a Role in Salivary Flow in Female Patients with Temporomandibular Disorders.

Aims: To explore the unstimulated salivary flow rate and subjective feeling of oral dryness in young adult women with temporomandibular disorders (TMD) and their relation to the presence of chronic pain, depression, somatization, and limited mandibular mobility.

Methods: Unstimulated whole saliva flow rate and presence of oral dryness were determined in 45 women with TMD and 30 healthy controls. The Research Diagnostic Criteria for TMD (RDC/TMD) were used for assessment of TMD, chronic pain, depression, somatization, and mandibular mobility.

Genetic Polymorphisms of Catechol-O-Methyltransferase: Association with Temporomandibular Disorders and Postoperative Pain.

Aims: To evaluate the association between catechol-O-methyltransferase (COMT) gene polymorphisms and temporomandibular disorders (TMD), TMD pain, psychosocial impairment related to TMD, and postoperative pain.

Methods: A total of 90 patients with a diagnosis of painful TMD and 92 matched controls were investigated for the presence of TMD, TMD pain, and psychosocial variables by the Research Diagnostic Criteria for TMD. In a prospective cohort study of 40 subjects who underwent extraction of at least one fully impacted mandibular third molar, subjects had 6 months post-surgery follow-up of postoperative pain.

Cephalometric analysis of the middle part of the face in patients with mandibular prognathism.

Background/aim: The middle part of the face, that is the maxilla, has always been mentioned as a possible etiologic factor of skeletal Class III. However, the importance of the relationship of maxillary retroposition towards the cranial base is still unclear, although it has been examined many times. The aim of this study was to conduct cephalometric analysis of the morphology of maxilla, including the whole middle part of the face in patients with divergent and convergent facial types of mandibular prognathism, as well as to determine differences betweeen them.

A cephalometric analysis of the cranial base and frontal part of the face in patients with mandibular prognathism.

Background/aim: The literature suggests different views on the correlation between the cranial base morphology and size and saggital intermaxillary relationships. The aim of this study was to investigate the cranial base morphology, including the frontal facial part in patients with mandibular prognathism, to clarify a certain ambiguities, in opposing viewspoints in the literature.

Methods: Cephalometric radiographies of 60 patients were analyzed at the Dental Clinic of the Military Medical Academy, Belgrade, Serbia.

TMD in class III patients referred for orthognathic surgery: psychological and dentition-related aspects.

Objective: To investigate temporomandibular disorders (TMD), psychosocial, and occlusal variables in class III orthognathic surgery patients with respect to the control subjects, and to compare psychosocial and occlusal features in class III patients with different Research Diagnostic Criteria for TMD (RDC/TMD) diagnoses.

Materials And Methods: The study enrolled 44 class III patients referred for orthognathic surgery and 44 individuals without a malocclusion. TMD, depression and somatization were assessed by RDC/TMD.

Temporomandibular disorders after orthognathic surgery in patients with mandibular prognathism with depression as a risk factor.

Objective: To examine the prevalence of temporomandibular disorders (TMD) after orthodontic-surgical treatment in patients with mandibular prognathism and analyze psychosocial variables related to TMD.

Materials And Methods: The case-control study comprised 40 patients with mandibular prognathism who underwent combined orthodontic-surgical treatment (orthognathic surgery group). Forty-two patients with untreated mandibular prognathism served as a control group.
