The laser made its first steps in the field of dentistry more than 20 years ago. Over time, techniques have evolved and have been perfected for use in dentistry and to become an essential use in our clinics today.
Using laser dentistry is not at the reach of everyone, and requires a keen knowledge in the field, as well as expertise.
The use of medical laser contributes to considerable progress in the field of dentistry. It is practiced in many procedures.
Each procedure requires the use of a given type of laser, respecting a protocol and a program of specific wavelength of the electromagnetic spectrum in order to achieve optimal results while working safely.
Using laser in restorative dentistry allows us to selectively remove dental caries and old composite fillings and requires minimal preparation. Waterlaser MD does not heat, does not create pressure and does not make the stressful noise we often have with the high speed dental drill. Also, anesthesia is not always required, which makes the session more comfortable for the patient. Compared to the classical drill, the laser does not create smear layer as it cuts, reducing the chance of a bacterial contamination and providing a better surface for bonding of the reparative preparation.
In addition to that, our clinics are equipped with a breakthrough innovation that will improve dramatically the precision of our preparation. Kavo DiagnoCam is a video camera that captures the tooth structures, allowing us to detect accurately tooth caries that are not visible to the professional eye and to target directly the caries without removing unnecessary tooth structure. This method allows us to be more precise in our diagnosis and treatments, aims to be minimally invasive and avoids it to evolve towards a more severe state.
Treatment of gummy smile has gone from the use of a conventional technique that was a traumatic experience to a pleasant treatment much more comfortable for the patient.
The use of the new waterlase technique in cosmetic gum surgery minimizes operative time and post-operative complications, promotes a faster healing and offers an immediate result.
The dentist removes the excessive gum tissue and re-shapes the bone in order to conserve the biological width of the teeth.
Due to the bactericidal effect and the haemostatic action of the laser, gum tissue heals within a few days without requiring any sutures and drug prescription.
3-Laser Pocket cleaning:
Deep gingival pocket cleaning is a very painful procedure that requires local anesthesia and can cause significant gum bleeding.
In our clinics, deep pocket cleaning is done by combining the use of laser diode and Emundo, a biocompatible colorant. Emundo will be stimulated through the diode laser irradiation killing effectively all the germs in deep pockets.
Compared to the classical treatment, laser deep pocket cleaning is painless to the degree of not requiring local anesthesia, has minimal gum bleeding, less operative time, and has faster post interventional healing time. The reduction in gum bleeding also minimizes bacterial translocation from the oral cavity to the blood stream reducing transient bacteremia which ultimately decreases cardiovascular incidents.
Dark spots and gingival hyper pigmentation can be treated by waterlase radiation in a defocused mode with a wavelength of 2780 nm.
It’s a safe, comfortable and effective procedure that is painless for the patient and provides an excellent aesthetic result.
5- Gum Grafting:
When a tooth root surface is exposed, a gum graft is needed to reduce consequently the tooth sensitivity.
Gum grafting can be a very simple procedure while it is performed with the waterlase technology: the operative time, the bleeding and the post-operative discomfort are all reduced making this procedure more acceptable for the patient. The gum will heal within a few days.
The laser teeth whitening system is a diode laser manufactured by biolase technology. It works on a specific wavelength of 810 nm that will efficiently photo-activate the whitener applied on the teeth.
The specific emission of the light at a certain wavelength, the exposure time, and the choice of the whitening gel impact together the whitening efficiency. It is safe and reduces the duration of treatment. It also avoids to heat excessively which affects the sensitivity and it will ultimately improve patient comfort and offer a great visible result.
Endodontic treatments aim to completely decontaminate the root canal system before adding to it a filling material which is called gutta-percha.
Current techniques which use manual instrumentation or rotary technology and that are combined with the use of antibacterial irrigating solutions, although traditionally used, offers some unpleasant drawbacks. In fact, they do reduce significantly the bacterial load in the canal; however, they leave a significant amount of smear layer that can increase the risk of treatment failures.
In addition, irrigating solution commonly known as sodium hypochlorite and chlorhexidine, despite their significant antimicrobial actions cannot, by themselves, be effective on all infecting microorganisms.
Waterlaser and diode lasers have shown great results in root canal disinfection and smear layer removal.
Waterlase is used in a photon-induced photoacoustic streaming method (PIPS). Its high peak power and its use of water induce a non-thermal photoacoustic wave when radial emitting laser tips and irrigating solutions are present in the canal. The root canal system, even secondary and accessory canals are completely cleaned and dentinal tubules are free of smear layer.
Diode laser is used to deeply decontaminate the dentinal walls through a high peak-pulse power that will kill effectively all bacteria.
The combined use of waterlase and diode laser in endodontic treatments optimize the decontamination of the canals before filling, which will guarantee the treatment success, and decrease the risk of treatment failure.
Laser dentistry can also be found within the pediatric department. It changes completely the general frightening perception of the dentist and it makes the dental session more pleasant for the child.
Using waterlase MD for cavity preparation, pulpotomy, root canal treatment or frenectomy is less traumatizing and painful than the classical drill and it reduces greatly fear and anxiety that children usually experience at the dentist’s.
Lasers have simplified and improved oral surgery procedures. Their great advantages rely on the precision of the incision of gum and bone in a less traumatic way than the conventional techniques. Also, their bactericidal and haemostatic actions improve the surgery quality and promote patient comfort as there will be less bleeding and pain in a shorter operative time. These techniques can be very interesting for patients under anticoagulant medications, as they don’t have to stop them to benefit from an oral surgery.
Waterlaser and diode laser promote a faster bone healing and improve osteogenesis due to their biostimulative properties. It can be very beneficial for extraction because it induces a better blood coagulation, as well as for: peri-implantitis treatments, for surgical incision and drainage due to dental infection, vestibuloplasty, frenectomies and many other oral surgeries.
Sometimes a lesion can be found on the lips, the tongue, the gum or the jaw. A biopsy must be performed in order to diagnose the presence or not of a disease.
If the dentist considers that the abnormal tissue is benign such as an aphthous ulcers or a mucocele (if the swelling is not persistent) he will remove the entire lesion (excisional biopsy). On the other hand, if the lesion seems large and malignant he will remove a sample and send it to an oral pathologist who will establish a diagnosis (incisional biopsy).
In our clinics, these procedures are performed with the waterlaser MD. Laser biopsies are more precise and many small lesions can be removed through a topical anesthetic. They lower inflammatory reactions, as the bleeding due to effective hemostasis, and accelerate the healing process, with less postoperative discomfort and the need of sutures.
