ABSTRACT
@#The continuous sequence of bone healing phases starts off with osteoconduction to the implant surface, depending on the migration of osteogenic cells. Osteoneogenesis ensues resulting in a mineralised interfacial matrix and is followed by bone remodelling to the implant interface at discrete sites. Dental implant drilling procedure and placement produce osseous defect which is filled by blood. Within seconds, blood proteins are adsorbed onto the implant surface and platelets are activated resulting in the release of cytokines and growth factors. Further platelet aggregation initiates osteoconduction to the surface, followed by osteoneogenesis, forming an extracellular matrix. Subsequently, remodelling creates a bone to implant interface which can be explained through distance and contact osteogenesis. The dental implant surface has been shown to influence osteoconduction by modifying protein properties and adsorption around the implant. Salivary biomarkers may be considered as a specific and sensitive diagnostic tool to detect these changes in protein expressions after implant placement. Thus, the purpose of this narrative review is to provide a detailed account of the bone healing mechanism associated with dental implant placement, as well as how the implant surface architecture and protein release play a role in bone healing, and the potential use of saliva to detect these biomarkers.
ABSTRACT
Objective:To explore the risk factors of oral fungal infection in patients with severe hepatitis, and the prevention role of nystatin oral care combined with precision health education on oral fungal infection.Methods:A total of 150 patients with severe hepatitis who were hospitalized for diagnosis and treatment in the First Affiliated Hospital of Zhengzhou University from February 2018 to February 2020 were selected as the research objects. According to the random number table method, they were divided into the observation group (given nystatin oral care combined with precision health education intervention) and the control group (given routine oral care combined with precision health education intervention), 75 cases in each group. The incidence of oral fungal infections in the two groups after the intervention were compared.Results:The fungal infection rate in the observation group at 1 week, 2 weeks and 4 weeks after intervention were 2.67% (2/75), 4.00% (3/75), 8.00% (6/75), which were significantly lower than 12.00% (9/75), 18.67% (14/75), 25.33% (19/75) in the control group ( χ2=4.81, 8.03, 8.11, all P<0.05). Four weeks after the intervention, among the 6 patients with fungal infection in the observation group, there were 5 cases of oral leukoplakia and foreign body sensation in the pharynx, and 1 patient with oral leukoplakia; among the 19 patients with fungal infection in the control group, all had oral mucosal leukoplakia. There were 17 cases of leukoplakia and pharyngeal foreign body sensation, and 2 cases of oral leukoplakia. Conclusions:Nystatin oral care combined with precision health education is of great significance in patients with severe hepatitis, and can effectively reduce the incidence of oral fungal infections.
ABSTRACT
BACKGROUND@#The physical environment can facilitate or hinder physical activity. A challenge in promoting physical activity is ensuring that the physical environment is supportive and that these supports are appropriately tailored to the individual or group in question. Ideally, aspects of the environment that impact physical activity would be enhanced, but environmental changes take time, and identifying ways to provide more precision to physical activity recommendations might be helpful for specific individuals or groups. Therefore, moving beyond a "one size fits all" to a precision-based approach is critical.@*MAIN BODY@#To this end, we considered 4 critical aspects of the physical environment that influence physical activity (walkability, green space, traffic-related air pollution, and heat) and how these aspects could enhance our ability to precisely guide physical activity. Strategies to increase physical activity could include optimizing design of the built environment or mitigating of some of the environmental impediments to activity through personalized or population-wide interventions.@*CONCLUSIONS@#Although at present non-personalized approaches may be more widespread than those tailored to one person's physical environment, targeting intrinsic personal elements (e.g., medical conditions, sex, age, socioeconomic status) has interesting potential to enhance the likelihood and ability of individuals to participate in physical activity.
