Where to Catch a Lie

This study in-progress explores the relationship between social awareness, deception detection, and eye movement patterns exhibited during deception detection. Specifically, we are searching for patterns in visual attention to facial/body areas during the evaluation of honesty that correspond to correct detection of lies. During this experiment, participants will complete a questionnaire to gauge their social awareness (i.e., cognizance of the indications of others’ needs and motivations in social situations). Subsequently, they will be fit with an eye-movement tracking device and watch a video of a college-aged actor pretending to be a student. In this role, the actor will be responding to questions about his personal experiences and behaviors while in college. We will instruct the actor to lie on half of his responses. While watching the video, participants will decide whether they perceive the actor’s responses to be honest or dishonest. In the results, we expect to find a positive correlation between level of social awareness and detection of deception. That is, participants who are more socially aware will be more likely to detect accurately when the actor is lying. Further, we expect to find patterns of participants’ eye movements, eye fixations, and gaze paths that correspond with the ability to detect deception. That is, these patterns will indicate consistent attention to those areas of face (e.g., eyes and mouth) and body (e.g., body language and hand-to-face movements) that have been shown to produce reliable cues for detecting deception (e.g., Bond, 2008).https://ecommons.udayton.edu/stander_posters/1980/thumbnail.jp

Changes in PGE2 signaling after submandibulectomy alter post–tooth extraction socket healing

Saliva is very important to oral health, and a salivary deficit has been shown to bring serious problems to oral health. There is scant information about the mechanisms through which salivary glands participate in post–tooth extraction socket healing. Therefore, the aim of the present study was to investigate the effect of submandibulectomy (SMx), consisting of the ablation of submandibular and sublingual glands (SMG and SLG, respectively), on PGE2 signaling and other bone regulatory molecules, such as OPG and RANKL, involved in tooth extraction socket healing. Male Wistar rats, 70 g body weight, were assigned to an experimental (subjected to SMx) or a control group (sham operated). One week later, the animals in both groups underwent bilateral extraction of the first mandibular molars. The effect of SMx on different stages of socket healing after tooth extraction (7, 14, and 30 days) was studied by evaluating some parameters of inflammation, including PGE2 and its receptors, and of bone metabolism, as well as by performing bone biomechanical studies. SMx increased TNFα and PGE2 content as well as cyclooxygenase-II (COX-II) expression in tooth socket tissue at almost all the studied time points. SMx also had an effect on mRNA expression of PGE2 receptors at the different time points, but did not significantly alter osteoprotegerin (OPG) and RANKL mRNA expression at any of the studied time points. In addition, an increase in bone mass density was observed in SMx rats compared with matched controls, and the structural and mechanical bone properties of the mandibular socket bone were also affected by SMx. Our results suggest that the SMG/SLG complex regulates cellular activation and differentiation by modulating the production of molecules intervening in tooth extraction socket repair, including the PGE2 signaling system, which would therefore account for the higher density and resistance of the newly formed bone in SMx rat.Fil: Mohn, Claudia Ester.

Parameters of oxidative stress in saliva from patients with aggressive and chronic periodontitis

Objectives: Free radicals play an important role in the onset and progression of many diseases. The aim ofthis study was to investigate the contribution of oxidative stress in the pathology of aggressive (AgP) andchronic (CP) periodontitis and its relation with the clinical periodontal status.Methods: Eighty subjects were divided into two groups: 20 patients with AgP and 20 patients with CP withtheir 20 corresponding matched controls, based on clinical attachment loss (CAL), probing pocket depth(PPD), and bleeding on probing (BOP). Saliva reactive oxygen species (ROS), lipid peroxidation, and nonenzymaticantioxidant defences were measured by luminol-dependent chemiluminescence assay, asthiobarbituric acid-reactive substances (TBARs) and total radical-trapping antioxidant potential (TRAP),respectively. Pearson?s correlation and multivariate analysis were used to determine the relationshipbetween ROS and TBARs and the clinical parameters.Results: ROS and TBARs were increased in AgP while TRAP was decreased, comparing with CP. In AgP, astrong and positive correlation was observed between ROS and TBARs and they were closely associatedwith CAL and PPD.Discussion: In AgP, but not in CP, oxidative stress is a high contributor to periodontal pathology and it isclosely associated with the clinical periodontal status.Fil: Acquier, Andrea Beatriz.

Esthetic rehabilitation with ultra-thin ceramic veneers and direct mock-up in the treatment of dental erosion – Case report

Indexación: Scopus.Dental erosion is a high prevalence condition characterized by the loss of dental substance due to chemical agents. It can also be associated with �physical wear, affecting function and aesthetics. Ceramic veneers can provide effective solutions to patients affected by erosive disorders, by means of an indirect approach and minimal intervention. Recent advances in cementation techniques and ceramic materials have allowed their use in reduced thicknesses, known as "dental contact lenses" or "ultra-thin veneers". They contribute significantly to the preservation of the dental structures, having excellent models or mock ups in order to preview the final outcome. Case: The aim of this report is to communicate the use of this technique for the treatment and successful 12-months follow-up of a patient affected by dental erosion of the maxillary central incisors. Special interest was placed on direct mock-up, which is a simple technique not requiring laboratory steps. Luting of the lithium disilicate veneers was carried out with a light-curing resin cement and try-in pastes, yielding a very satisfactory result. Conclusion: Diagnosis and early treatment of this disorder allows the application of conservative techniques, such as ultra-thin veneers, which are seen as a promising alternative treatment to full coverage restorations and traditional ceramic veneers. © 2018, Universidad de Concepcion.

Helicobacter Pylori Infection of Lingual Dorsum: Risk of Gastric Infection Helicobacter Pylori

The role of Helicobacter pylori in the oral cavity has been researched/studied by our study group for the last 28 years. At that time, there wasn’t a clinical entity that included Burning, Lingual Papillary Hypertrophy and Halitosis (BHH) together. However, the patients who presented this condition did not find an effective response to their demand. In some cases, a therapeutic diagnosis of Chronic Candidiasis was made in relation to Lingual Papillary Hypertrophy and they were referred to Periodontics Services for their Chronic Halitosis for evaluation and treatment. Many of these patients did not resolve their clinical symptoms, in their subsequent check-ups. The burning of the mouth was usually diagnosed as Burning Mouth Syndrome. A considerable percentage (60%) of these patients reported suffering from chronic gastric discomfort without receiving treatment, because when they consulted with the physician or with the gastroenterologist, their symptoms were associated with stress.Fil: Muiños, Antonio Luis.

Incisivo lateral superior con dos raíces y dos conductos. Caso Clínico.

Las anomalías en la morfología del incisivo lateral superior son de muy baja frecuencia. Las anomalías de desarrollo radicular pueden presentarse como alteraciones tanto en el número de conductos, como en el número de raíces, así como en ambas regiones a la vez. En el presente trabajo, se reporta el caso de un paciente que se presenta a la consulta con malestar en el incisivo lateral superior izquierdo. En la radiografía preoperatoria se detectó la presencia de dos conductos y dos raíces, sin anomalía morfológica de su corona clínica, con requerimiento de tratamiento endodóntico. Concluimos que una correcta interpretación de las imágenes radiográficas preoperatorias es esencial, para poder detectar estas variantes y tomar las consideraciones necesarias para el adecuado tratamiento endodóntico.Fil: Martinez, P..
