Lasers used to regenerate damaged teeth
Conclusion This laboratory study has shown that low-power laser therapy can direct dental stem cells to grow into one type of dental tissue, dentin. A strength of the study is that it used the dental pulp from molar teeth in rats, which are similar to humans, rather than their incisors, which are open-rooted and continue to grow for life to replace loss from gnawing. Limitations highlighted by the authors include: the small sample size as a result of the limited availability of these particular rodents technical difficulties of growing minute rodent teeth widespread growth of dental tissue, which the authors think is because of the large area that was exposed to laser – they are hopeful that this can be improved with better technique and in larger animals and humans Other factors that will need to be taken into account are that although the authors wanted to create a way to stimulate the cells without the toxic effects of chemicals or transplant, there is still the potential for side effects from the laser therapy. It is not yet known if the laser therapy stimulates other unwanted cell production or whether it might damage other cells. Further research is required before this technique could progress to human trials, but it is a promising start. There is also the possibility that laser therapy could be used to stimulate the production of other specialised cells. Even if the research progresses well, it would probably be at least a decade bef...
Mona Randolph, 82, of Missouri, is only one of three polio survivors left in the US that uses an iron lung machine, which is no longer made and leaves her with responsibility of repair and maintenance.
Publication date: Available online 20 August 2018Source: NeurocomputingAuthor(s): Junjie Zhang, Yong Xia, Haoyue Zeng, Yanning ZhangAbstractDetection of pulmonary nodules on chest CT is an essential step in the early diagnosis of lung cancer, which is critical for best patient care. In this paper, we propose an automated pulmonary nodule detection algorithm, denoted by NODULe, which jointly uses a conventional method for nodule detection and a deep learning model for genuine nodule identification. Specifically, we first use multi-scale Laplacian of Gaussian (LoG) filters and prior shape and size constraints to detect nodul...
ConclusionLow PNI predicts poor survival in LC patients.
CONCLUSIONS: This study shows that IHC with the tested antiserum increases the sensitivity of the diagnosis and may be recommended for routine use in EMB analyses of cardiac transplant patients with Chagas disease.
This study demonstrates that small peptide domains derived from native protein amelogenin can be utilized to construct a mineral layer on damaged human enamel in vitro. Six groups were prepared to carry out remineralization on artificially created lesions on enamel: (1) no treatment, (2) Ca2+ and PO43- only, (3) 1100 ppm fluoride (F), (4) 20 000 ppm F, (5) 1100 ppm F and peptide, and (6) peptide alone. While the 1100 ppm F sample (indicative of common F content of toothpaste for homecare) did not deliver F to the thinly deposited mineral layer, high F test sample (indicative of clinical varnish treatment) formed mainly C...
Conclusions: Oral health promotion and disease prevention is an emergent need for older adult populations residing in urban and rural communities of the state of Texas. Analysis revealed that the majority of the older adult populations in both settings to have financial and socioeconomic barriers to access preventative and restorative dental care services.

The objective of this project was to integrate preventive oral care into pediatric oncology care. . METHODS: This project consisted of an educational program for pediatric oncology providers who completed pre- and postprogram surveys assessing oral health knowledge, attitudes, and practice; attended an oral health education session; and performed oral assessment and fluoride varnish application on children during cancer treatment. . FINDINGS: Three major outcomes resulted from this project. PMID: 28945720 [PubMed - in process]
Poor oral health afflicts many low-income and other vulnerable populations. Poor oral health can lead to unnecessary tooth decay, periodontal disease, plaque buildup, pain, and even the quiet and deadly advancement of oral cancer. It also leads to unnecessary and expensive visits to the emergency department to treat pain of tooth decay and periodontal disease but not the causal conditions. Finding ways to improve oral health in low-income communities is essential to good health and helping individuals move from poverty to middle class status.
A dentist is simply a doctor in charge of your oral hygiene. So, let me ask you a question: How many times have you visited a dentist this year? Alright, you don't have to tell me your answer. Most people don't visit a dentist until they have severe problems in their oral area. I am also part of this group even if I don't want to admit it. This is because most people are unaware of the importance and usefulness of a dentist. It is recommended that you visit a dentist at least twice in a year to keep your gums and teeth healthy. Dental visits are supposed to start at the age of 8 years when the permanent teeth are repl...
