Synthesis of wrinkled mesoporous silica and its reinforcing effect for dental resin composites

Dental resin-based composites have been widely used as hard tissue substitutes to restore dental caries and other defects since the early 1960s, thanks to their superior aesthetics and biocompatibility over dental amalgams [1 –4]. These composites are primarily comprised of inorganic filler particles dispersed in a resin matrix which can be polymerized under a blue light irradiation. Despite recent advances in the optimization of monomer structures and filler compositions, the fracture of resin composite restorations i s still one of the main causes for failure in clinical applications, which prevents their applications in high-load and large area restorations [5–8].

Abstract Khat or qat (Catha edulis) is a plant that grows in East Africa and southern Arabia. The leaves and twigs of this small tree are chewed by several millions of people worldwide for their stimulating amphetamine‐like effects. The reported prevalence of khat chewing in Europe and the USA is on the rise, especially with global migration. Long‐term khat chewing has several detrimental general and oral health effects. The aim of the present study was to review the current literature regarding khat use and its association with oral and dental diseases, with particular emphasis on its link with oral keratotic white le...

Dental caries is a ubiquitous infectious disease with a nearly 100% lifetime prevalence. Rodent caries models are widely used to investigate the etiology, progression and potential prevention or treatment of the disease. To explore the suitability of these models for deeper investigations of intact surface zones during enamel caries, the structures of early-stage carious lesions in rats were characterized and compared with previous reports on white spot enamel lesions in humans. Synchrotron X-ray microcomputed tomography non-destructively mapped demineralization in carious rat molar specimens across a range of caries sever...

CONCLUSIONS: We demonstrated periodontal deterioration in JGSDF personnel after a 7-day training. Behavioral changes, especially discontinuation of regular toothbrushing, fostered dental plaque maturation, resulting in inflammatory changes in participants' periodontal condition. The results indicate the importance of performing toothbrushing at least once over a 7-day training period for prevention of periodontal deterioration. The regimen could be applicable to evacuees from disasters because they are under conditions of stress that may limit oral hygiene activity. PMID: 28810984 [PubMed - in process]

ConclusionsThe lack of scientific knowledge on hereditary sensory and autonomic neuropathy due to the rarity of the disease often results in a delay in diagnosis, which is of substantial importance for the prevention of many complications and symptoms. Interdisciplinary work of specialized medical and dental teams and development of a standardized treatment protocols are essential for the management of the disease. There are many knowledge gaps concerning the management of patients with hereditary sensory and autonomic neuropathy-VIII, therefore more research on an international basis is needed.

Dental caries caused 63,000 children to be admitted to hospital for surgery in 2014. In that year, approximately one-quarter of British five-year-olds suffered with tooth decay and more than one-third of children did not see a dentist

This article reviewed smoking related systemic diseases and oral diseases. Smoking is related to lung cancer, cardiovascular diseases and many other systemic diseases. Cigarette smoke affects the oral cavity first, so it is evident that smoking has many negative influences on oral cavity, for example, staining of teeth and dental restorations, wound healing, reduction of the ability to smell and taste, and development of oral diseases such as oral cancer, periodontitis, smoker's palate, smoker's melanosis, hairy tongue, leukoplakia, oral candidiasis and implant survival rate. The article also discusses the relationship bet...

The research community has for some years now seemed on the verge of making real progress in the elimination of tooth decay and periodontal disease. That final leap from understanding and promising research to earnest clinical development always takes longer than we'd like it to, however. The most pressing and widespread dental issues are largely bacterial in origin, but not quite as straightforward as simply identifying one unwanted type of microbe and getting rid of it. This is a story of interactions between the behavior of different species, and the need to eliminate harmful behavior without disrupting the activities o...

tin Hoeft In lower middle-income economies (LMIE), the nutrition transition from traditional diets to sugary foods and beverages has contributed to widespread early childhood dental caries. This qualitative study explores perceived risk and protective factors, and overall experiences of early childhood nutrition and oral health in indigenous Ecuadorian families participating in a community-based oral health and nutrition intervention. Dental exams of 698 children age 6 months through 6 years determined each child’s caries burden. A convenience sample of 18 “outlier” families was identified: low-caries...
