Much progress has been made in understanding the genetic contributions to isolated forms of cleft lip and palate, however this effort is yet to be translated to enhanced genetic counseling or prevention strategies. Interest in the topic was renewed with the ability to perform genome-wide genotyping and after a few of those relatively larger scale studies, many are considering more targeted efforts and to focus on specific genes and/or loci. Here we discuss this crossroad and suggest targeted approaches and rethought clinical descriptions are a better way to move the field forward...

OBJECTIVE: Although the "mouthwatering" to sight, smell, or thought of food is commonly accepted in food and nutrition research, the concept of mouthwatering and human salivary flow conditioning is not well accepted in salivary research. The objective of this study was to revisit whether human salivary flow could be classically conditioned to a previously neutral stimulus. DESIGN: Sour candy or a non-food control in opaque containers were presented to healthy participants (n = 8)...

OBJECTIVE: To determine the effect of different nonsteroidal anti-inflammatory drugs (NSAIDs) on vascular endothelial growth factor (VEGF) gene expression in two osteoblast cell populations. DESIGN: Osteoblasts obtained by primary culture (HOp) and human osteosarcoma cell line MG63 (MG-63), which were treated with 10 μM doses of acetaminophen, indomethacin, ketoprofen, diclofenac, ibuprofen, ketorolac, naproxen or piroxicam. At 24 h of treatment, their gene expression of VEGF was evaluated by real-time polymerase chain reaction (RT-PCR) and compared with the expression in untreated cells (control group)...

OBJECTIVE: To investigate the mesial cervical concavity of maxillary first premolars and its relationship with root and canal configuration using cone-beam computed tomography (CBCT). DESIGN: Images of maxillary first premolars (n = 1056) were collected from patients (n = 601) who had undergonein vivo CBCT scanning. The root and canal number and morphology were evaluated. The following measurements of the mesial cervical concavity of the maxillary first premolars were evaluated in section images: dentine thickness (in concavity at the cemento-enamel junction), concavity angle, depression depth (distance from mesial dentinal surface at concavity to mesial proximity), concavity position (distance from mesial dentinal wall at invagination to the top of the mesial marginal ridge)...

OBJECTIVE: To investigate the change of Th1/Th2/Th17 cytokines and human beta defensin 2 (HBD-2) in HIV-infected patients with oral candidiasis (OC) and gather information about OC-specific immunity. DESIGN: During the 1st year of highly active anti-retroviral therapy (HAART), 25 HIV-infected patients were followed up at the baseline, 3rd, 6th, 12th month. At each visit, oral manifestations were examined; oral rinses were collected and cultured for Candida; peripheral venous blood was taken to determine CD4 + T cell counts and HIV RNA viral load (VL); both unstimulated whole saliva and peripheral venous blood were taken to determine cytokine (IL-4, IL-17(A/F), IFN-γ) and HBD-2 levels...

OBJECTIVE: The aim of this study was to evaluate the epigenetic changes in the process of oral carcinogenesis by screening the methylation of repair genes in chronic smokers. DESIGN: Two groups were formed: Group 1: 16 smokers with consumption of 20 cigarettes/day for at least 10 years; and Group 2: 10 non-smoking. Exfoliative cytology of the tongue was performed, and the extracted DNA was treated by enzymes. The PCR Array System performed methylation screening to evaluate 22 DNA repair genes, and the results were validated by RT-qPCR for each gene with methylation levels ≥10%...

OBJECTIVE: Polymorphonuclear neutrophils (PMNs) are the most abundant innate immune cells and are also important effectors in the maintenance of oral health. However, little is known about the effects of saliva on the PMN. We therefore aimed to investigate the effect of saliva on the PMNs' morphology and functioning. DESIGN: Effect of saliva on the membrane integrity of PMNs isolated from blood was evaluated with FACS using Annexin V (apoptosis marker) and propidum iodide (membrane integrity marker)...

OBJECTIVE: An oral cavity is a place especially susceptible to oxidative damage. It is subjected to many environmental pro-oxidative factors or factors that have the ability to generate reactive oxygen species (ROS). The aim of this article is to present the main sources of ROS and oxidative stress in the oral environment. DESIGN: A literature search was performed using the PubMed and Google Scholar databases. RESULTS: One of the most important ROS sources in the oral cavity is periodontal inflammation...

PURPOSE: This study evaluated the role of anti-tumor immune response of curcumin on tongue squamous cell carcinama (TSCC). EXPERIMENTAL DESIGN: Cell lines (Cal 27, FaDu) and animal model (4NQO mice model) were uesd in this study. The MTT assay was used to detecte cell proliferation. The Western blotting, immunohistochemistry and immunofluorescence were used to examine the protein expression. The flow cytometry was performed to determine the number of Treg and MDSC...

In previous research, to combine the immunogenicity of Fusobacterium nucleatum (F. nucleatum) and the probiotic properties of Lactobacillus acidophilus (L. acidophilus), we constructed a FomA-expressing L. acidophilus strain and assessed its immunogenicity. Our findings indicated that oral administration of the recombinant L. acidophilus strain reduced the risk of periodontal infection by Porphyromonas gingivalis (P. gingivalis) and F. nucleatum. However, because the exogenous FomA is an heterologous protein for the original bacterium, in this study, we assessed whether the biochemical characteristics of the recombinant L...

OBJECTIVE: To assess changes in orofacial tactile sensitivity and gnawing related to capsaicin-mediated cutaneous, myogenic, and arthrogenic nociception in the rat. DESIGN: After recovery from anesthesia, orofacial tactile sensitivity and gnawing were assessed using operant testing methods following capsaicin application. Twenty female CD-Hairless rats were tested with bilateral capsaicin cream application to the cheek or with isoflurane anesthesia alone. Following several weeks of recovery, animals (n = 20) received either 10 μL unilateral masseter injections of vehicle, or phosphate buffered saline (PBS) to assess injection sensitization...

OBJECTIVE: Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is a birth defect for which several genes susceptibility genes been proposed. Consequently, it has been suggested that many of these genes belong to common inter-related pathways during craniofacial development gene-gene interaction. We evaluated the presence of gene-gene interaction for single nucleotide polymorphisms within interferon regulatory factor 6 (IRF6), muscle segment homeobox 1 (MSX1), bone morphogenetic protein 4 (BMP4) and transforming growth factor 3 (TGFB3) genes in NSCL/P risk in Chilean case-parent trios...

OBJECTIVES: Following chewing a solid food, the median particle size, X50 , is determined after N chewing cycles, by curve-fitting of the particle size distribution. Reduction of X50 with N is traditionally followed from N ≥ 15-20 cycles when using the artificial test food Optosil® , because of initially unreliable values of X50 . The aims of the study were (i) to enable testing at small N-values by using initial particles of appropriate size, shape and amount, and (ii) to compare measures of chewing ability, i...
