The human host defense peptide, LL-37, is an important player in the first line of defense against invading microorganisms. LL-37 and its precursor, hCAP18, have been detected in unstimulated whole saliva but no reports showing hCAP18/LL-37 in isolated, parotid, and/or submandibular/sublingual saliva have been presented. Here, we measured the levels of hCAP18/LL-37 in human parotid and submandibular/sublingual saliva and investigated the expression of hCAP18/LL-37 in parotid and submandibular gland tissue. Parotid and submandibular/sublingual saliva was collected from healthy volunteers, and the levels of hCAP18/LL-37 in saliva were analyzed by dot blot, ELISA, and western blotting...

Interleukin 12 (IL-12) is an inflammatory cytokine that promotes the response of the immune system. This cytokine has been implicated as a potent stimulator of several diseases characterized by inflammatory-induced bone destruction, such as rheumatoid arthritis and periodontitis. Yet, the exact role of IL-12 in the development and progress of periodontitis has not been clarified. Several studies have demonstrated a positive correlation between the level of IL-12 and the severity of periodontal destruction. Deletion of IL-12 in mice with periodontitis significantly suppressed the level of bone destruction...

The aims of the study were to determine the severity of halitosis and the association between oral hygiene practices and the severity of malodor in patients with dental and laryngological etiologies of genuine halitosis. Thirty-five laryngological and 40 dental patients with halitosis completed a structured interview and underwent laryngological and dental examinations. Halitosis was assessed using organoleptic and halimeter tests. Greater halitosis severity in laryngological patients was associated with worse clinical status of the palatine tonsils, less frequent toothbrushing, less frequent use of tongue cleaners, fewer daily meals, and increased use of mouthrinses...

Oral squamous cell carcinoma (OSCC) affects approximately 30,000 people and is associated with tobacco use. Little is known about the mechanistic effects of second-hand smoke in the development of OSSC. The receptor for advanced glycation end-products (RAGE) is a surface receptor that is upregulated by second-hand smoke and inhibited by semi-synthetic glycosaminoglycan ethers (SAGEs). Our objective was to determine the role of RAGE during cigarette smoke extract-induced cellular responses and to use SAGEs as a modulating factor of Ca9-22 OSCC cell invasion...

Dentistry is a science-based profession that has a close interaction with people and society. However, despite this close interaction, perceptions of the dental profession by both patients and dental professionals have received little research attention. The purpose of this study was to compare the perceptions of dentists, dental students, and patients toward the dental profession through the development and testing of the Dental Profession Perceptions Scale (DPPS). The DPPS contains a total of 17 items measured on a 5-point Likert response scale...

Human dental pulp stem cells (DPSCs) are oral mesenchymal stem cells with potential to differentiate into various cell types. Recent studies of DPSCs have focused on microRNAs (miRNAs), a class of small noncoding RNAs that play crucial roles in regulating DPSC phenotypes. In the current study, the expression of miR-140-5p was significantly decreased during lipopolysaccharide (LPS)-mediated differentiation of DPSCs in vitro. Overexpression of miR-140-5p enhanced proliferation of DPSCs and inhibited DPSC differentiation, whereas suppression of miR-140-5p produced the opposite effect...

Suboptimal adaptation of fixed dental prostheses (FDPs) can lead to technical and biological complications. It is unclear if the computer-aided design/computer-aided manufacturing (CAD/CAM) technique improves adaptation of FDPs compared with FDPs made using the lost-wax and metal casting technique. Three-unit FDPs were manufactured by CAD/CAM based on digital impression of a typodont model. The FDPs were made from one of five materials: pre-sintered zirconium dioxide; hot isostatic pressed zirconium dioxide; lithium disilicate glass-ceramic; milled cobalt-chromium; and laser-sintered cobalt-chromium...

Bone sialoprotein (BSP) is a glycoprotein associated with mineralized tissues. In this study, we investigated the regulation of Bsp transcription by calcium hydroxide [Ca(OH)2 ] in rat osteosarcoma-derived osteoblast-like ROS 17/2.8 cells and stromal bone marrow cells. Application of Ca(OH)2 (0.4 mM) increased the levels of runt-related transcription factor 2 (Runx2) and BspmRNAs at 3 and 6 h and the level of BSP protein at 12 h. Transient transfection analyses were performed using chimeric constructs encompassing different regions of the rat Bsp gene promoter ligated to a luciferase reporter gene...

Homeobox protein MSX-1 (hereafter referred to as MSX-1) is essential for early tooth-germ development. Tooth-germ development is arrested at bud stage in Msx1 knockout mice, which prompted us to study the functions of MSX-1 beyond this stage. Here, we investigated the roles of MSX-1 during late bell stage. Mesenchymal cells of the mandibular first molar were isolated from mice at embryonic day (E)17.5 and cultured in vitro. We determined the expression levels of β-catenin, bone morphogenetic protein 2 (Bmp2), Bmp4, and lymphoid enhancer-binding factor 1 (Lef1) after knockdown or overexpression of Msx1...

Oral health-related quality of life (OHRQoL) is an important patient-reported outcome measure in dental research. This study was conducted to analyse the association between OHRQoL, as measured using the five-item version of the Oral Health Impact Profile (OHIP-5), and different socio-economic indices. A national survey of randomly selected adult individuals in Sweden (n = 3,500) was performed using telephone interviews. The questions asked for the purpose of this study were defined by the items of the OHIP-5, just as questions were asked regarding socio-economic variables, including education, income, and economic resources...
