Filter by:Despite extensive research on periodontitis, little attention has been given to the symptoms and perception of peri-implant diseases and their impact on oral health-related quality of life. The study aims to assess patient perception of these diseases and their impact on quality of life through a cross-sectional observational study. Patients will be recruited from the Unit of Periodontics at "Le Scotte" University Hospital and will undergo diagnosis followed by questionnaire assessments. No follow-up visits are planned, and validated questionnaires will be administered to evaluate perception and impact on quality of life. Study procedures will include recording biometric peri-implant parameters and administering questionnaires such as the Brief Illness Perception Questionnaire (BIPQ) and Oral Health Impact Profile-14 (OHIP-14).
The goal of this observational study is to examine the effect of designs using different aesthetic dental proportions made with the digital smile design program on the aesthetic perception of individuals of different ages, gender, and educational status. The main questions it aims to answer are: 1. The golden ratio is the most aesthetic ratio known and accepted in dentofacial structures. 2. There is no significant difference between the aesthetic perception of dental students, dentists, specialist dentists and laypeople. Participants will answer: - The first 5 questions related that demographic data such as age, gender, and educational status. - The smile designs of a woman and a man, prepared according to 8 different principles, will be evaluated by the participants according to the Likert scale. Researchers will compare the 4th and 5th-grade students of a dentistry faculty, dentists, specialist dentists and laypeople to see the effect of smile design on facial aesthetic perception.
The investigators plan to examine the relation of perceptual variables-basic vision, unusual perceptual experiences(including but not limited to visual hallucinations)-to relevant functional variables such as cognition, mood, and alertness/sleepiness in an online sample of persons with Parkinson's disease (PwPD). It is hypothesized that unusual perceptual experiences will relate significantly to the selected variables. Participants do not need to experience visual hallucinations to be able to participate in this study. This is an observational study only, and not an interventional study.
During the exploration of surfaces with the bare finger, vibratory signals arise and propagate through the finger and hand. While research into mechanical and neural response characteristics has demonstrated that these signals carry rich information about touched objects and their properties, only little is known about the role these propagation waves play in human perception and to which extent the somatosensory system is able to collect information from afferents at more proximal locations than the skin-object surface. Using ring-block anaesthesia (lidocaine) we will temporarily inhibit haptic feedback sensations of healthy participants' index finger during interactions with 3D-printed surface probes that are systematically varied in two important material dimensions, namely their roughness and hardness (elasticity), while the participants carry out a well-established psychophysical discrimination task. The results will then be compared to a control condition without anaesthesia. An accelerometer sensor, placed on the dorsal side of the hand, will serve to simultaneously record the propagating tactile waves. Given their role in material perception, thermal cues will be monitored during the experiment with a thermometer and the hydration level of the fingertip skin will be measured regularly using a corneometer. This research will allow us to understand the role of propagation waves in material perception. It seeks to uncover some of the perceptual mechanisms that remain intact during surface discrimination of textured, compliant surfaces, while local information is temporarily inhibited. The results will have implications for how we provide feedback about material properties for sensorimotor control to this living with prosthetic limbs. It is hypothesised that propagation waves that arise during these haptic interactions contain behaviourally relevant information used for the discrimination of surface properties.
The satisfactory recovery of the patient after a surgery with an anesthetic request is very important for a quality and excellence assistance. The quality of recovery questionnaire QoR-15 was validated by their authors in 2013 with the study titled development and psychometric evaluation of a postoperative quality of recovery score: the QoR-15. This questionnaire allows a comprehensive assessment by associating the physiological parameters until then assessed with the subjective personal perception of the patient of his state of health. With the consent of its original author, this study is carried out to validate the questionnaire in Spanish and adapted to our environment.
Effective communication is a critical component of managing pandemic outbreaks like COVID-19. This study explores COVID-19 related public knowledge, perceptions, belief in public health recommendations, intent to comply with public health recommendations, trust in information sources and preferred information sources. Participants are invited to include detailed free-text answers to make sure their COVID-19 experiences are heard.
Using eye-tracking technology, the aim of this observational study is to compare the visual interests between attending physicians and residents watching a Cannot Intubate/Cannot Oxygenate (CICO) scripted and simulated scenario
The aim of this observational study is to compare the visual interests between residents in high-fidelity simulation practice
The long-term goal of this research is to advance our knowledge of how the brain combines the information of multiple sensory systems coding for spatial orientation and how adaptation to vestibular imbalance influences spatial orientation. In healthy human subjects verticality perception is accurate while upright. After prolonged roll-tilt, humans show a systematic bias in perceived direction towards the previous roll-tilted position (so-called "post-tilt bias"). Here we evaluate different potential explanations for this bias using both vision-dependent and vision-independent paradigms of verticality perception.
The purpose of this study is to explore emerging physical therapy practice in palliative care, and the perceptions of physical therapists regarding their care of the functionally dependent elderly, including: (1) the role and utilization of palliative care intervention in current practice, (2) current and potential goal-setting practices which may relate to palliative care, and (3) therapists' awareness of cultural and psychosocial issues in patient care.
