There is no vibration as there is with a normal dental drill. A suitable dental laser can be used like a scalpel to reshape or remove gum tissue, and the concentrated heat produced can effectively kill bacteria in pockets of diseased gum tissue. This technology can also be useful for biopsy where a small amount of tissue is removed for examination under a microscope to identify early cancer. The higher energy forms of lasers can be used to eradicate bacteria in dental decay lesions of teeth and even to remove hard tooth tissue avoiding the need to drill in some cases.

Despite the quickness with which our society has become accustomed to having everything, all at once, educational reform and progression is still a slow-turning gear in the great machine of time. The truth is that the face of K education is in a constant state of change. Educators that have been in the field for several decades may notice that the speed at which changes in methodology and student population are taking place is on a high-speed course compared to the past.
Many factors play into this but none as strongly as technological advancements. The Internet, wireless devices and improvements in communication all heighten the immediacy of information both within and without the classroom. This is both a blessing and a curse, of course.
It is really too soon to tell if the first Internet-raised generations will fare better or worse in life and succeed on a global scale. The assumption is that technology equals improvement and I would argue that overall, it is a true statement.
More access to information and a shrinking world can only lead to beneficial results for K students. The children graduating from high school in the next decade will have a broader view of the world than ever before and that is thanks to traditional geographic boundaries becoming non-issues in communication, workforce and learning.
I take no issue with the actual technology. Where I see existing and potential problems is in the indirect effects of technology on the comprehension habits of our youngest learners. You have to look at the overall influence of rapidly advancing technology to realize how it is also an obstacle to K classrooms.
In its broadest sense, technology has totally transformed the way that our children view life. A recent study by Common Sense Media for children age eight or younger found that 72 percent have computer access at home.
Television use is almost universal, with 98 percent of children in this age group having at least one at home and 10 percent reporting that theirs is kept on all the time.
While television consumption by children is nothing new, programs targeted toward toddlers and even infants are on the rise. Consider cable and satellite television staple Baby First TV. The channel plays continuous programming aimed at infants and toddlers that is commercial free.
I bring this up not to spark a debate about whether this type of television viewing is helpful or hurtful to developing youngsters; I mention it as an example of just how ingrained screen culture has become in the lives of our kids.
The journal Pediatrics found that between the ages of birth and six, kids watch an hour-and-a-half television per day.
These measurements do not even address indirect exposure, which puts the amount of time a television plays in the background at four hours per day for kids under the age of two.
Love it or hate it, screen culture is a foundational element of the contemporary American childhood. As a result, our kids arrive at Kindergarten with an advanced idea of instant gratification. They know that any game, program or form of communication is available at the touch of a button.
This easy access to everything translates to the way that these children are programmed for learning, especially when moments of frustration arise.
It has always been very difficult to keep the attention of students, particularly in the elementary set, but advancements like smartphones, tablets and Web sites directed at young learners have complicated this truth even more. Teachers and administrators today must find ways to keep students interested but not completely abandon tried-and-true methodology.
Thus the great problem with technology takes its toll on K classrooms across the nation. An electronic book has a lot of appeal: Since students are so comfortable with touchscreen methods, it stands to reason that reading may actually come more easily when learned through an electronic device.
The problem again is not that the technology harms the actual learning mechanics, but it leads to another issue altogether.With so many models out there, finding the perfect inversion table can be very tricky. It’s easy to get confused between hundreds of models out there, and invest in an inversion table that will waste your time in the best case, and pose a risk to your health in the worst case.
