Lasers are finding their way into dentistry in a big way based on the benefits that they can fetch one. They work to be a good way to ensure that you get the best of surgical tool that can be used effectively on soft or hard tissue.
Laser Peridontal Surgery is a non-invasive and an extremely gentle way of avoiding scalpel and sutures. There are mild or severe gum diseases and in such cases the best form of treatment for them is the use of laser treatment. The use of the Laser Peridontal Surgery goes on to eliminate bacteria in the mouth by as much as 90% and this can be a great way to keep gum disease at bay. The other merit of the Laser Peridontal Surgery is that you won’t have to deal with loss of gum tissue. There is no pain or bleeding involved when you use Laser Peridontal Surgery as no cutting or invasive methods are needed.
There are several different kinds of applications in which the laser can be used in the field of:
There are different kinds of lasers used in periodontics:
Nd: YAG Laser Diode Laser
The thing about diode lasers is that they have great soft tissue ablation and haemostatic characteristics. On the other hand, when they are applied to the root surface or alveolar bone, carbonisation and thermal injury may occur. Consequently, these lasers are used in the treatment of gingivectomy, frenectomy and other soft tissue procedures. Lately Er:YAG and Erbium chromium doped: Yittrium selenium-gallium garnet laser scaling has been seen as an adjunct to conventional scaling and root debridement. These lasers efficiently and successfully ablate iological tissues that contain water molecules.
The use of lasers during periodontal therapy can be extremely beneficial as there is hardly any bleeding, swelling and discomfort to the patient during the dental surgery. Nevertheless, each laser has different wavelengths and power levels that allow it to be used at different frequencies and gives the most safety during different kinds of periodontal procedures. There may be injury caused to periodontal tissues in case of an inappropriate wavelength and/or power level is used during a periodontal procedure.
The key to successful treatment of chronic periodontitis is the gain of clinical attachment level. Various dental laser wavelengths have been used by clinicians in treatment of periodontitis. Most commonly used lasers by dentists are diode lasers, Nd:YAG , Er:YAG and Er, Cr:YSGG and CO2. Lasers can also be used for pocket decontamination procedures.
Laser technology to treat gum problems and soft tissue concerns
Healthy gums after pockets elimination and disinfection using dental lasers
Laser mediated periodontal therapy is used to decrease the sub gingival bacterial loads. Laser assisted new attachment procedure is done with them to remove the unhealthy tissue. Lasers such as Erbium lasers work effectively in being able to remove the calculus build up on teeth and reducing progressive periodontal diseases. They demonstrate safe and effective root substance removal without any kind of negative thermal effects. Diode lasers result in a remarkable amount of reduction in subgingival microbial populations with it. The carbon dioxide wave length is effective in removing the soft tissue and the inflamed pocket tissues while achieving good hemostasis.
Lasers can address the concern of soft tissue problems:
Lasers are used in soft tissue surgery. The advantages of lasers in soft tissue surgery are:
This makes certain that lasers have a shorter operative time and faster postoperative recuperation period.
The uses of soft tissue lasers in dental practice broadly fall into these categories:
1. Improving gingival shape and contour,
2. Lengthening crowns,
3. Idealizing tooth proportionality, and
4. Resolving crown/height asymmetries
5. Frenectomy procedure.
Final aesthetic outcome of dental treatment are gingival shape and gingival contour. Gingival shape is all about the curvature of the gingival margin of the tooth. Gingival contour is different from gingival shape and refers to a more 3-dimensional description of gingival topography.
The best gingival contour has sharp interdental papillae and equally tapered gingival margins at the cervical margin of the teeth. Re-contouring is possible with the help of a diode laser. As there is no bleeding, the wound is sealed during the procedure, and contouring can be extremely accurate. Three weeks after gingival shaping and contouring, the tooth has a much more aesthetic look to it on the whole.
Contouring of the Gums
Excess gum Tissue Reshaped Using Lasers
There are specific lasers that can be used for frenectomy and they are called Diode lasers. The diode light and the mechanics used for it have changed the field of dentistry completely. The entire process is completely pain free and could be used with infiltrated local anesthesia. Topical anesthesia is given and then the procedure is performed. The duration of treatment with lasers is very slow as there is no pain induced. The procedure need not have stitches and therefore the healing is fast and free of all complications.
Lasers are also used to treat another form of gum disease which is drug induced gingival overgrowth. Medicines like phenytoin, calcium channel blockers such as nifedipine, procardia etc, antihypertensive tablets, and immunosuppressant causes gingival inflammation. To control gingival swelling by drugs, good oral hygiene is a must and no one can do away with it. If the condition is relentless, then lasers can be used for the removal of excessive gum tissue and contouring of the soft tissues to produce functional and aesthetic results.
Denture hyperplasia is a smooth tumor like mass which forms in the space that exists between the cheeks and the gums. This is the result of a constant irritation caused by dentures that don’t fit one well. If this is noticed then the best thing is realignment or replacement of the existing denture. Lasers can be used to reduce tumor like mass.
Lasers can also be used for gum bleaching and the method used is called the water lease system. Erbium:YAG lasers is a secure and well-organized treatment. It causes alteration in the melanin pigment in gingival tissues and produces a great pink-looking gum. It is a method that is fast, painless and ensures that one gets good results. Dark gums look ugly and they can be changed into pink and healthy looking ones in a single one sitting with a dentist. The good thing is that the results are not temporary and will last you a lifetime. The way melanin pigment worked on by the laser, it does allow the dark gums to return.
Depigmentation of Gums by Lasers
The patient needs to find out the cause of the discoloration. Healthy gums with no gum disease in them such as swelling or inflammation are perfect for gum bleaching. However, if the gums are not healthy then first the infection needs to be treated. Gum bleaching can only be done on healthy gums. A smoker needs to quit smoking before opting for the gum bleaching.
Lasers as an addition to scaling and root planning (SRP)
Diode lasers are used as an addition to scaling and root planning. Lasers are far better in their efficiency when you compare them with more conventional treatment options. They are good enough to be able to control the bleeding. Scaling and root planning along with the use of laser go on to produce reasonable clinical improvement when compared to conventional scaling and root planing.
The healing of lasers is usually very predictable as the cell is vaporized as it was cut. Many dentists opt to use a combination of the blade and laser for hemostasis and refining the tissue margin. In incising and draining of the abscess, the laser is used for hemostasis and tissue vaporization. This ensures that there is less of an open wound that could result in an infection due to the nearness of pus and bacterial drainage. Before the use of lasers, the dentists used epinephrine injection for hemostasis.
Now, laser is used for hemostatic and makes it a simple and uncomplicated procedure. This ensures that the use of laser is the best instrument for a advanced, exact, hemostatic cut.
