Laser and Dentistry
Although LASER is not a “Magic wand’’, each and every field of medicine utilizes the benefits of it and dentistry is not an exception.
Research on application of laser in dentistry began when Ralph H Stern & Reider F Sognnaes1(1963) of Los Angeles School of Dentistry, University of California studied thermal effect of ruby laser on dental hard tissues & restorative materials. Since then there had been attempts to utilize the benefits of laser in each and every field of dentistry. Laser may be used in dentistry effectively for their ability to incise, cut and ablate soft and hard tissues. In 1965, Leon Goldman first reported the case of laser exposure to a vital human tooth2.

Laser tissue interaction mainly contributes to absorption. The dental laser wavelength lies in the near, mid and far infrared region. The basic properties such as selective absorption, coagulation, sterilization and stimulatory effects are the most important parameters for selecting lasers for dentistry. The following lasers and their corresponding wavelength are commonly used for soft tissue interactions. In short dental lasers are relatively easy to use if the dentists have been trained properly. The lasers function with an end cutting action while other dental instruments are side cutting. Each wavelength has its own unique interactive qualities and laser operators’ skill plays a major role in making laser as a success tool in dentistry. Erbium lasers are also used for hard tissue treatment in dental surgery. Erbium lasers are unique in that they are the only lasers that can cut both hard and soft tissues. Oral and Maxillofacial surgery was the forerunner in using laser. There were attempts to replace surgical scalpel with electrocautery and later with laser. Some of the added advantages of Laser are
• Better haemostasis,
• Controlled depth of penetration,
• Reduced pain

Ankyloglossia (attachment of heavy lingual frenum prevents normal functioning of tongue) and they are introverted due to the difficulty in normal speech.
We see ankyloglossia in many adolescent patients (attachment of heavy lingual frenum prevents normal functioning) and they are introverted due to the difficulty in normal speech. Micropulsed CO2lasers(for ablation of soft tissues) with char-free settings(30 Hz, 300mJ) was used to achieve minimal collateral thermal damage in ankylogossia. There was a little or no bleeding during surgery and suturing was contraindicated as healing takes place in advance (10). It was reported that the speech improved dramatically after surgery.
CO2 lasers have been popular in oral surgery due to their precise incisions and excellent hemostasis. It is commonly used laser for incisional & excisional biopsies.(PecaroBC,GarchumeWJ.The CO2 laser in Oral and maxillofacial surgery. J.OralMaxillofacSurg 1983.41:725-728ii.clinical application of the CO2Laser in Laser in dentistry …Ch.10 p145.
One of the advantages of CO2 in removing malignant lesion from oral cavity is being minimal bleeding, less postoperative pain ,precise cancer diodes surgery and minimal metastasis. Indicated power setting rangesfrom 4-10
As mentioned beforehand flaccid dysarthria occurs when there is damage to the lower motor neurons, specifically the region affected is the pons and the medulla located in the lower brainstem. An injury at this site is going to cause any number of the following characteristics to manifest: breathiness, hypernasality, short phrases, monopitch, imprecise consonants, diplophonia, poor intelligibility, impairment in elevating the tongue, drooling and or poor lip seal. Basically any of the subsystems of our speech system can be affected such as resonance, articulation, phonation, respiration and/or prosody. The damage that is caused to the lower motor neurons can be attributed ...
From the time Caroline began preschool she had a severe speech sound disorder. She had a lisp along with difficulty producing what she referred to as harsh sounds, such as the sound /r/. The lisp caused difficulty in producing /th/ which was produced in the form of /s/. The sounds that gave her the most trouble were the lingua-dental. There was extreme difficulty in the articulation of her tongue to produce the sounds, and in order to compensate for not being able to say the words properly she began to omit the sounds she could not produce. Her speech language pathologist explained to her that she had a lazy tongue. It was described to her that she did not know how to properly move her tongue in the specific ways to produce the specific sounds. When Caroline was asked what she thought had caused her speech disorder, she thought it was because she had a delay in her verbal abilities and poor mouth structure as her mouth was narrow, and teeth were very crooked. However, the underlying cause was not known.
Jajou, I questioned the maintenance of his career. What I acquired was that dental practices all vary and this question does not have one general answer. Dr. Jajou currently owns his own practice, which means he his in charge of his office and pays his employees making his salary higher than common dentists. Professional organizations and conferences are not important in the overall outlook of dentistry. On the other hand, Dr. Jajou had plenty to say about the technology used in dentists’ offices. Digital dentistry, or the use of dental technologies, involves lasers, digital scanners, and x-ray machines. However, only dental laboratory technicians use this expert machinery. Dentists use drills, mouth mirrors, probes, forceps, brushes, and scalpels on patients. Later, I asked why he is excessively passionate about oral health from seeing how captivated he is to answer my questions. In the same manner he responds describing how oral health is a huge part of overall health because plaque can affect can cause heart problems and other major health issues beyond your
The natural methods are less likely to cause a scar. But laser treatments have many side effects depending on a number of factors. First and foremost are you prone to keloid scars? Also if a laser is too powered, it causes skin damage. It also depends on how treatments one will undergo. Avoiding scars is usually expensive because you have to for an expert with a good reputation. To remove scars you may have to consult a scar removal specialist and this comes at a cost and it’s time consuming.
First of all I’d like to start with an overview of radiography. Radiography is the process of an image being created on a film or digital receiver by way of radiation exposure. This radiograph allows the dental team to view and diagnose the images in hopes of providing the patient with the appropriate oral health care. The x-ray was discovered by Wilhelm Conrad Roentgen and he received the Nobel Prize in physics in 1901 for his discovery. Professor Roentgen’s breakthrough allowed others to build upon his work and further its usefulness in fields such as dentistry, specifically oral radiography in dental offices.
Pediatric Dentistry is a fantastic job for me considering how much I adore children, the median annual wage is excellent, and dental hygiene is greatly preeminent to me. I cannot envision a better career path for myself. I have always been a person who can interact easily with children. In addition, I also enjoy the idea of being able to help children feel great about their teeth and smile. Being a dentist is much more to me than just cleaning a child's teeth. It is also about boosting the child's self-confidence by encouraging them to brush their teeth and take care of their smile

The laser procedure is much faster than the surgical operations. Moreover, regular visits are also not required to derive benefit of the treatment.
Steel blades are not the only form that a scalpel takes. Scalpels are now in the form of lasers. The use of lasers began with a laser knife. The CO2 laser was used to remove cancerous tissue. Later the Nd:Yag laser was used.
Erbium or YAG laser which is of precise wave length penetrates into the skin. As the scattering of the YAG lasers are less, the normal skin is left unaffected.
Laser therapy has been accepted widely by the general public and the medical professionals for its extensive benefits. This therapy precisely targets the affected area, minimizes the use of general anesthesia, encourages shorter hospital stay and improves the patient outcomes. These benefits have lead to its increased use and importance worldwide.
Dentistry is an industry that is constantly evolving. Every day new techniques, instruments, procedures and discoveries are made. One thing becoming more and more popular in dentistry are dental lasers. Dental laser use in dental offices is rapidly growing because all of the advantages they provide to both the dentist and the patient. With the different types and strengths of the different lasers like hard tissue, soft-tissue, carbon dioxide, argon lasers and more almost any dental treatment can be benefited by using one. Lasers are allowing procedures to be performed quicker, more effectively and more comfortably.
Nowadays the practice of dentistry is becoming more challenging and complex because of the information explosion regarding dental materials and equipment, increasing need for continuous professional development and an increasingly litigious society. Hence there has been a paradigm shift towards evidence-based healthcare .
Abstract: A laser is a electron device that produces a very narrow, powerful beam of light. The essential components of a laser include an active medium, an energy source, and an optical cavity. The optical cavity itself is enclosed by the resonator which has a mirror at each end. The energy that is put into the laser causes the atoms of the active medium to be excited to a higher energy level. When these atoms relax back down to their ground level they emit photons, which is part of a chain reaction that may cause other atoms to go through the same energy transitions resulting in light that becomes so intense that part of it exits through one of the mirrors as a very strong beam, known as a laser.
As you can see lasers are a very useful and important tool which is why I have
