Laser in dental clinic
What types of treatments can laser be used in the dental clinic?
- Oral surgery treatments (including dental implantology) with no side effects such as bleeding, pain and edema (swelling). Explanation: Laser sections but at the same time coagulates (closes) blood vessels, having also an anti-inflammatory effect over the tissues. Compared with the drill or surgical saw, when sectioning, laser does not reach bone tissue so therefore does not determine vibrations and overheating, namely tissue necrosis. When excising soft tissue growths, we perform frenectomies or gingivectomies, incisions are precise, bleeding is minimal or nonexistent and healing is sensational. Most of the times we don’t even use local anesthetic and eliminate scalpel and suture wires.
- ER YAG laser used for gingival retraction cases, endodontics (root canal treatments) and oral surgery. Usually, these types of treatments don’t require anesthesia. Extremely useful in periodontal pocket treatment, when the dentist will place the beam between the root and bone, in pocket’s depth, for sterilizing and healing stimulation of damaged tissues, so that the gums can again adhere to the dental cervix (neck).
- Gingival smile: with dental lasers excess gingival tissues that cover the crown can be reshaped, leading in healthy bone and dental structure exposure, considerably improving smiles in which excess gums are exposed.
- Teeth whitening: laser units with low intensity for soft tissues can be used to accelerate the chemical process of whitening products performed within the dental practice.
- Far superior psychological comfort for anxious (frightened) patients. Explanation: dental turbines emit a characteristic and unmistakable sound, of high intensity, which some patients can feel “up to the brain”. Laser is based on a totally different principle so these unpleasant high intensity sounds are replaced by low intensity and low volume sounds, much easier to tolerate.
- Lack of sensitivity and pain. Explanation: Laser beam, at certain intensity, acts directly on the nerve endings from dentin tubules, assuring automatic anesthesia of the nerve ending. Therefore, sensitive teeth, with gum retraction, dental cervix or dental root decay can be perfectly treated with laser. In addition, in most cases there is no sensitivity associated with profoundly decayed teeth, with a recent filling, mechanically traumatized by the dental drill and chemically by the filling material.
- Advantages of cavity cleaning with lasers: superior preservation of structures unaffected by decay. Explanation: Structures affected by decay are more sensible to the laser’s action than the healthy ones, so when the laser fascicle passes above the decayed tissue, it will be removed without damaging the healthy tissue.
What are the advantages of laser therapy?
- Minimally invasive due to the precisely controlled beam, laser produces a minimum tissue sacrifice, considerably reducing treatment duration and post-operatory recovery. When cleaning enamel and dentin, laser sections with precision, and with the lack of vibration, prevents enamel fractures, as dental drills would have caused.
- Anesthetic reduction For many patients, the best part of surgical laser therapy is not using needles for treatment or surgery, anesthesia being reduced or even removed.
- Reduction of bleeding – bleeding is reduced to minimum and suture necessity can be eliminated. Laser also provides sterilization of treated area. Dental laser attenuates bleeding because the high energy light beam helps exposed blood vessels clotting (coagulation), thus preventing blood loss, an extremely important aspect for patients with diabetes, heart conditions and hemophilia.
- High-risk patients due to maximum control over bleeding, there is no hemorrhage or post-operatory infection risk. Bacterial infections are reduced to minimum due to the high energy light beam which sterilizes tissues where procedures are performed.
Dental lasers for soft and hard tissuesA large range of lasers can be used to diagnose, assist and perform different dental procedures. However, two large laser categories can be discussed:
- Hard tissue lasers: Basic use of hard tissue lasers is to perform sections within bone and teeth. Hard tissue lasers are often used with the purpose of cleaning the tooth of decay, preparing surfaces for filling, removing dental structures for crown covering, to cut and model maxillary bones.
- Soft tissue lasers: We can section, cut and remove gum, mucous, tumors and frenulums from the oral cavity. Canal nerves can be removed through vaporization, we can sterilize periodontal pockets and infected canals. Soft tissue lasers penetrate the soft tissue closing blood vessels and nerve endings. This is the main reason for which people never experiment any post-operatory pain after laser use. Also, soft tissue lasers allow faster tissue regeneration.
Laser in Pediatric DentistryPediatric laser dentistry is a promising field in modern minimally invasive dentistry, and it can be “child friendly” approach.
Dental lasers offer many advantages like avoiding needles and high-speed hand pieces, which makes less traumatic experience and improves behavioral management of the child. Recent advances in laser technology and research have set the stage of revolution in pediatric dental practice to provide optimal, preventive, interceptive and restorative dental care in a stress free environment.
Lasers can be successfully and safely used on a wide range of the dental treatments. such as children and pregnant women, unlike some prescribed and/or sulcularly delivered drugs. Unlike with those medications, the patient will not experience allergic reactions, bacterial resistance, or untoward side effects when the laser is used.
