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...

AbstractTo validate a Spanish language translation of the ASAS Heath-Index (ASAS-HI) testing, its reliability, construct validity, and responsiveness in Colombian patients with spondyloarthritis. Translation was done following a forward-backward procedure. Patients fulfilling the Assessment of Spondyloarthritis international Society (ASAS) criteria for either axial or peripheral spondyloarthritis (SpA) participated. Test-retest reliability was assessed by intra-class correlation coefficient (ICC) in patients without treatment changes. In patients who required a therapeutic intervention, responsiveness was assessed using th...

The objective of the study was to compare the effects of shockwave therapy and laser therapy on pain, neck functionality, and quality of life in patients with myofascial pain syndrome of the trapezius. 61 patients (>  18 years) were randomly allocated to two treatment groups: (1) 31 patients received soft laser therapy once daily in a 3-week period for a total of 15 sessions, (2) 30 patients received shockwave therapy once in a week for 3 weeks, totalling 3 treatments. Resting pain and pain tolerance were as sessed by a 100 mm visual analogue scale; functional status and quality of life were measur...

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...

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...
